Substitute Part Grouping Explanation

The UB204KW036B-3JB and UB204KW036B-2B are parametric equivalents within the UB2 series. Substitution is valid based on the following criteria:

• Identical electrical ratings: 3.3V forward voltage and 20mA maximum current
• Identical optical characteristics: white lamp color, white diffused lens
• Identical mechanical specifications: square panel cutout (0.69" x 0.69"), 15.00mm lens size, square flat-top lens style
• Identical compliance certifications: ROHS3 compliant, REACH unaffected
• Identical moisture sensitivity level: MSL 1 (unlimited)

Both parts share the same base product number (UB204) and series designation (UB2), confirming their functional equivalence. The suffix variation (-3JB vs -2B) reflects packaging or internal configuration differences that do not affect electrical or mechanical performance in standard applications.

Parameter Comparison

Engineering Selection Recommendations

Both UB204KW036B-3JB and UB204KW036B-2B are Active status components with identical ROHS3 and REACH compliance certifications. Selection between these parts should be based on inventory availability and packaging requirements specific to procurement workflows. The UB204KW036B-3JB currently maintains 1031 units in stock, while UB204KW036B-2B maintains 914 units. Both parts meet all regulatory and environmental compliance requirements for applications requiring white diffused LED panel indicators at 3.3V operation.

Frequently Asked Questions (FAQ)

Q: Can UB204KW036B-2B be used as a direct replacement for UB204KW036B-3JB?

A: Yes. Both parts are parametric equivalents with identical electrical ratings (3.3V, 20mA), optical characteristics (white diffused lens), and mechanical dimensions (0.69" x 0.69" panel cutout, 15.00mm lens size). No circuit modifications or PCB layout changes are required.

Q: What determines substitution eligibility between these two parts?

A: Substitution is valid when the following parameters match: forward voltage, maximum current, lamp color, lens color, lens transparency, panel cutout dimensions, lens size, lens style, and compliance certifications. Both parts satisfy all these criteria.

Q: Are there any packaging differences between UB204KW036B-3JB and UB204KW036B-2B?

A: Both parts are supplied in Bulk packaging. The suffix variation (-3JB vs -2B) does not affect electrical performance or mechanical compatibility in standard applications.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both UB204KW036B-3JB and UB204KW036B-2B are ROHS3 compliant and REACH unaffected, with identical Moisture Sensitivity Level 1 (unlimited) ratings.

Q: Which part should be selected based on availability?

A: Selection should prioritize current inventory levels and procurement lead times. UB204KW036B-3JB has 1031 units available, while UB204KW036B-2B has 914 units available. Both are functionally interchangeable.
