Is there a pin-compatible replacement for XL-304UBD?

Yes, parts like XL-304UBC and TZ-L2-03YYBB2WCJ30-001 are pin-compatible in their 3mm, 2-pin package. However, they are not functionally identical due to differences in lens type and brightness.

What risks should I check before replacing XL-304UBD?

Before replacing XL-304UBD, you must check the visual appearance. Key risks include changes in light distribution (diffused vs. focused beam) and brightness, which can affect the product's user interface.

XL-304UBD Alternatives, Datasheet & Cross Reference | XINGLIGHT

Finding a replacement for the XL-304UBD, a standard 3mm blue diffused LED, involves matching its package, color, and electrical characteristics. The main challenge is finding a part with an identical diffused blue lens and 600mcd brightness.

AI replacement insight

Electrical risklow

Candidates have compatible voltage and current ratings.

Package risklow

All viable candidates share the same 3mm through-hole package.

Application riskmedium

Lens type and brightness differences will change the visual output, which may not be acceptable for the user interface.

Can it be replaced directly?

No direct drop-in replacement has been identified; all strong candidates have visual differences in lens type or brightness that require engineering review.

Best replacement path

Review XL-304UBC for a brighter option from the same manufacturer, or TZ-L2-03YYBB2WCJ30-001 for a similar brightness with a different lens.

Main risk

The primary risk is a mismatch in visual appearance due to different lens types (diffused vs. transparent/white) or brightness levels.

Recommended alternatives

A 3mm blue LED from the same manufacturer with a different lens type and higher brightness.
