Is there a pin-compatible replacement for XL-3216SURC-FB?

XL-3216SURC is a likely pin-compatible alternative in the same 1206 package. As a 2-pin device, compatibility is high, but datasheet review is recommended to confirm polarity marking and land pattern.

What risks should I check before replacing XL-3216SURC-FB?

Key risks include differences in luminous intensity (brightness) and minor variations in dominant wavelength (color shade). Always verify the candidate's datasheet for these parameters and test in-circuit.

XL-3216SURC-FB Alternatives, Datasheet & Cross Reference | XINGLIGHT

Finding a replacement for the XL-3216SURC-FB red LED involves matching its 1206 package, forward voltage, and luminous intensity. Several alternatives exist, but careful review of optical characteristics is required.

AI replacement insight

Electrical risklow

Forward voltage is compatible.

Package risklow

Package is identical.

Firmware risklow

Not applicable for this component type.

Can it be replaced directly?

XL-3216SURC is a likely direct replacement, but its wider luminous intensity range (80-240 mcd vs. 80-120 mcd) means some units may be brighter than the original.

Best replacement path

The most promising path is XL-3216SURC, a variant from the same manufacturer, which minimizes electrical and mechanical risks.

Main risk

The primary risk is a potential variation in brightness, as the candidate part has a wider luminous intensity specification.

Recommended alternatives

A strong alternative from the same manufacturer with a matching 1206 package, red color, and compatible electricals.
