Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HLMP-2735 is determined by the following critical parameters:

• Configuration match: Bar - 2 High, DIP format
• Color specification: Yellow (x 2) LEDs
• Voltage rating: 2.1V nominal operation
• Mounting type: Through Hole DIP package
• Lens style: Rectangle with Flat Top geometry
• Regulatory compliance: REACH Unaffected status

The KB2735YW from Kingbright qualifies as a substitute based on matching all critical parameters. Variations in current rating (30mA vs. 20mA), millicandela output (23mcd vs. 38mcd), wavelength (590nm vs. 583nm), and lens size specifications are within acceptable tolerance ranges for circuit board indicator applications where the primary function is visual status indication rather than precision illumination.

Parameter Comparison

Engineering Selection Recommendations

The KB2735YW represents the primary substitute for the obsolete HLMP-2735. Selection of this alternative is supported by:

• Active product status ensuring continued availability and supply chain reliability
• Full compliance with REACH regulations matching the original component
• Identical voltage rating and mounting configuration enabling direct PCB integration
• Matching MSL classification (1 - Unlimited) for standard storage and handling conditions
• RoHS3 compliance providing enhanced environmental and regulatory standing

The KB2735YW is suitable for applications where the HLMP-2735 is no longer procurable. Circuit designs utilizing the original component can transition to this substitute without PCB layout modifications due to identical through-hole DIP configuration and lens geometry.

Frequently Asked Questions (FAQ)

Q: Can the KB2735YW be used as a direct replacement for the HLMP-2735?

A: Yes. Both components share identical configuration (Bar - 2 High, DIP), color (Yellow x 2), voltage rating (2.1V), mounting type (Through Hole), and lens style (Rectangle with Flat Top). PCB footprints are compatible without modification.

Q: What are the differences in electrical performance?

A: The KB2735YW operates at 30mA maximum current versus 20mA for the HLMP-2735. The substitute produces 23mcd brightness compared to 38mcd for the original. Peak wavelength differs by 7nm (590nm vs. 583nm), remaining within the yellow LED spectrum. These variations are acceptable for indicator applications where visual status confirmation is the primary function.

Q: Are there compliance or regulatory differences?

A: Both components maintain REACH Unaffected status. The KB2735YW adds RoHS3 compliance, providing additional environmental certification. No regulatory barriers exist to substitution.

Q: What is the impact of the diffused white lens type on the KB2735YW?

A: The diffused white lens on the substitute provides light scattering characteristics that may alter perceived brightness distribution compared to the original component. This affects visual appearance but does not impact functional indicator operation in standard circuit board applications.

Q: Are there inventory considerations?

A: The HLMP-2735 is obsolete with limited remaining stock (1240 pcs). The KB2735YW is an active product with established supply (636 pcs in current inventory), ensuring long-term availability for new designs and production runs.
