Price remains an important part of electronic component sourcing. If two suitable parts are available from dependable suppliers, the lower price may be the sensible choice. But the unit price tells only part of the story. A component must also be available when it is needed, meet the required standards and continue to support the product throughout its intended life.

Purchasing teams need to consider supply and risk alongside price. That wider view is particularly valuable when sourcing components for products that must remain in production or service for many years.

Availability can outweigh a small saving

A low quotation is of little use if the supplier cannot deliver enough parts to meet a production schedule. Stock levels can change quickly, and an attractive price may apply only to a limited quantity. Delivery dates also need scrutiny: an estimated lead time offers less reassurance if it frequently changes.

Buyers therefore need to ask how much stock is actually available, where it is held and whether the supplier can meet future requirements. Paying slightly more for a dependable supply may cost far less than delaying production while a missing component is found.

A component costing only a few pence can hold up an entire assembly. In that situation, the saving on the purchase order is insignificant compared with the cost of interrupted production.

Consider the component’s remaining life

A part may be easy to buy today but unsuitable for a product expected to remain in use for years. Manufacturers regularly update product ranges and discontinue older components. A part approaching the end of its manufacturing life could become difficult to source before the finished product reaches the end of its own life.

Lifecycle status is therefore an important consideration during design and purchasing. If a component is no longer recommended for new designs, the engineering team may need to assess an alternative. If changing the design is impractical, the business may need to plan how it will secure enough genuine stock to meet future production, maintenance and repair needs.

These decisions can have a much greater financial effect than a modest difference in the original unit price. Redesigning a board, qualifying a replacement or delaying deliveries can all add substantial cost.

Check quality and traceability

Scarce components can attract offers from unfamiliar sources. Although a low price or a promise of immediate delivery may be tempting, buyers need confidence that the parts are genuine, correctly identified and suitable for their application.

Counterfeit or nonconforming components can cause failures during manufacture or after a product has reached the customer. Even when a problem is discovered before use, investigating the parts, replacing stock and recovering lost production time can be expensive.

A supplier’s quality procedures, documentation and approach to testing should therefore form part of the buying decision, particularly for obsolete and hard-to-find components. The level of checking required will depend on the application and the information available about the stock.

Look beyond the immediate supplier

Supply risk can also arise further back in the chain. A part made at one factory, or by only one manufacturer, may be vulnerable to disruption even when several distributors list it for sale. Restrictions on trade, transport problems or changes at the manufacturing site can affect future availability.

Understanding whether genuine alternatives exist helps businesses make better decisions. In some cases, a second source can be qualified. In others, the original component may be essential, making advance planning more important.

Compliance needs attention too. A favourable price cannot make up for a component that fails to meet the requirements of the intended product or market. Buyers may need documentation relating to RoHS, REACH or other applicable requirements, depending on where and how the finished product will be used.

Finding the best overall value

The best purchasing decision is rarely based on one number. Price should be weighed against the quantity available, realistic delivery times, lifecycle status, quality assurance and the consequences of a supply failure. This is especially true when an obsolete component is needed to keep an established product in production.

Auckland International helps businesses source obsolete and hard-to-find electronic components through its worldwide network of contacts. We can investigate availability against a specific part number and your requirements, while our quality processes help you make informed purchasing decisions. If a component is proving difficult to find, contact us with the part number and quantity you need, or simply search our component database, which will give you current stock levels.
