Repeat Reliability: Supporting Legacy IR Designs with the SFH 9500

The Challenge: Finding a Trusted Source for a Legacy Infrared Component, twice

A Germany-based electronics manufacturer had a familiar challenge: they needed to restock a component their production relied on, OSRAM's SFH 9500, a compact infrared-emitting diode used in industrial sensors, proximity detectors, and medical devices.

Although still listed on paper, the part had become increasingly difficult to find in the real world, especially in the quantity and quality they needed.

They first reached out to Maketronics months ago. We delivered quickly and reliably, with full traceability. So when the same need came up again, they returned to us with confidence.

Why the SFH 9500 Wasn’t Just Another Part

The OSRAM SFH 9500 plays a key role in many legacy designs thanks to its:

• Narrow emission angle

• Compact form factor

• Peak wavelength of 935 nm

It is a go-to component for:

• Proximity and gesture sensing

• Industrial automation systems

• Wearables and medical monitoring equipment

Replacing it with a newer part would have meant mechanical redesigns, optical recalibration, and weeks of testing, not to mention additional costs. Sourcing the exact part wasn’t just a preference; it was a necessity.

Our Role: Consistency That Earns Confidence

When the second requirement came in, we handled it just like the first:

✅ Sourced authentic SFH 9500 stock from trusted suppliers

✅ Ran quality checks to ensure consistency with the previous batch

✅ Delivered to Germany on schedule

✅ Maintained a competitive price, even in a tight market

What That Meant for the Customer

• A second successful delivery, based on earned trust

• Consistent quality and packaging

• No delays, no redesigns, and no risk

• Strengthened relationships in the EU market

When Trust Turns into Momentum

At Maketronics, we don’t just supply components, we build reliability into your supply chain. This repeat order proves that when the stakes are high and the parts are rare, manufacturers need more than just a quote. They need someone who delivers, every time.
