Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the KB-G100SRW is determined by the following critical parameters:

Primary Compatibility Criteria:

• Configuration: Bar - 2 Wide, DIP (dual-segment LED bar format)
• Color: Red (x 2) (dual red LED segments)
• Mounting Type: Through Hole (PCB insertion compatibility)
• Lens Type: Diffused optics (light distribution characteristics)

Secondary Electrical Parameters:

• Voltage Rating: 1.85V nominal (acceptable range: 1.85V to 2.0V for direct substitution)
• Current: 30mA nominal (acceptable range: 20mA to 185mA with circuit design consideration)
• Wavelength - Peak: 660nm nominal (acceptable range: 635nm to 660nm for red LED spectrum)
• Millicandela Rating: 120mcd nominal (brightness variation acceptable within application tolerance)

Compliance Requirements:

• RoHS3 Compliant
• REACH Unaffected
• ECCN: EAR99

Substitute parts must maintain identical configuration and mounting characteristics while operating within specified electrical parameter ranges.

Engineering Selection Recommendations

KB-G100SURKW (Kingbright - MFR Recommended Substitute)

The KB-G100SURKW is the manufacturer-recommended substitute for the obsolete KB-G100SRW. Both components share identical base product number (KB-G100) and configuration (Bar - 2 Wide, DIP). The KB-G100SURKW maintains ROHS3 compliance and REACH unaffected status. Electrical parameters fall within acceptable substitution ranges: voltage rating of 1.95V versus 1.85V, and wavelength peak of 645nm versus 660nm remain within red LED spectrum tolerance. The higher current rating (185mA versus 30mA) and lower millicandela rating (56mcd versus 120mcd) require circuit design verification for brightness and power dissipation compatibility. Active product status ensures ongoing availability.

HLMP-2670 (Broadcom Limited - Similar Alternative)

The HLMP-2670 provides an alternative substitute option from Broadcom Limited. This component maintains the required Bar - 2 Wide, DIP configuration with dual red LEDs and through-hole mounting. ROHS3 compliance and REACH unaffected status are confirmed. Electrical parameters are compatible: 2V voltage rating and 20mA current are within acceptable ranges for red LED bar indicators. Wavelength peak of 635nm falls within red spectrum tolerance. The lower millicandela rating (45mcd versus 120mcd) indicates reduced brightness output. Lens type specifications are not provided for this component. Active product status supports long-term supply availability.

Frequently Asked Questions (FAQ)

Q: Can KB-G100SURKW directly replace KB-G100SRW without circuit modification?

A: The KB-G100SURKW shares identical configuration and mounting type. However, the higher current rating (185mA versus 30mA) and lower brightness (56mcd versus 120mcd) require circuit design review. Existing current-limiting resistor values must be recalculated for the new voltage rating (1.95V versus 1.85V) to ensure proper operation.

Q: What is the brightness difference between KB-G100SRW and its substitutes?

A: KB-G100SRW delivers 120mcd. KB-G100SURKW provides 56mcd (47% of original). HLMP-2670 provides 45mcd (38% of original). Application brightness requirements must be evaluated against these reduced output levels.

Q: Are wavelength differences between 660nm, 645nm, and 635nm significant?

A: All three wavelengths fall within the red LED spectrum. The 660nm (KB-G100SRW) represents deep red, while 645nm (KB-G100SURKW) and 635nm (HLMP-2670) represent standard red. Visual color perception differences are minimal in typical indicator applications.

Q: What are the voltage and current implications for circuit design?

A: KB-G100SRW operates at 1.85V/30mA. KB-G100SURKW requires 1.95V/185mA (6.2x higher current). HLMP-2670 requires 2V/20mA. Existing current-limiting resistor networks must be recalculated for each substitute to maintain proper LED operation and prevent overcurrent conditions.

Q: Are all substitutes through-hole mounted?

A: Yes. KB-G100SRW, KB-G100SURKW, and HLMP-2670 all feature through-hole mounting for DIP package insertion into PCB headers or sockets.

Q: Do all substitutes meet compliance requirements?

A: Yes. All three components are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards.

Q: What is the product status difference between the main part and substitutes?

A: KB-G100SRW is classified as Obsolete. Both KB-G100SURKW and HLMP-2670 are Active products, ensuring continued manufacturing and supply availability for new designs and production runs.
