KB-H100SRW LED Indicator Bar Equivalent & Substitute Parts

Part Overview

The KB-H100SRW is an LED Circuit Board Indicator Bar manufactured by Kingbright, classified as a single DIP red diffused indicator with through-hole mounting. This component is designed for circuit board applications requiring visual status indication. The part maintains Active product status with full RoHS3 compliance and unlimited moisture sensitivity rating (MSL 1).

Substitute parts are identified when equivalent electrical performance and mechanical compatibility can be maintained across the same functional category. Alternative sources become necessary due to inventory availability, supply chain optimization, or design flexibility requirements while preserving circuit performance.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict alignment with the following critical parameters:

Primary Compatibility Criteria:

• Configuration: Bar - Single, DIP (identical form factor required)
• Mounting Type: Through Hole (identical PCB assembly method)
• Lens Style: Rectangle with Flat Top (identical physical profile)
• Current Rating: 30mA (identical operating current)
• Color: Red (identical visual output category)

Secondary Compatibility Parameters:

• Voltage Rating: Tolerance range 1.7V to 2.0V (acceptable forward voltage variation for series resistor adjustment)
• Wavelength - Peak: Range 634nm to 660nm (red spectrum compliance)
• Millicandela Rating: Minimum 80mcd (acceptable luminous intensity variation)

Compliance Requirements:

• RoHS3 Compliant (mandatory)
• MSL 1 (Unlimited) (mandatory)
• REACH Unaffected (mandatory)
• Active product status (mandatory)

Both identified substitute parts meet all primary and secondary compatibility criteria.

Parameter Comparison

Engineering Selection Recommendations

HLMP-2685 (Broadcom Limited):

This substitute maintains full electrical and mechanical compatibility with the KB-H100SRW. The forward voltage rating of 2.0V represents a 0.15V increase from the main part, which is accommodated through standard series resistor adjustment in typical LED circuit designs. The wavelength peak of 634nm remains within the red spectrum classification. The millicandela rating of 80mcd is 27% lower than the main part; this reduction in luminous intensity must be evaluated against application brightness requirements. All compliance certifications (RoHS3, MSL 1, REACH Unaffected) are maintained. Tube packaging is suitable for automated assembly processes.

SSB-LXH100SRW (Lumex Opto/Components Inc.):

This substitute provides superior luminous intensity at 150mcd, representing a 36% increase over the main part. The forward voltage of 1.7V is 0.15V lower than the main part, requiring minimal circuit adjustment. The wavelength peak of 660nm matches the main part exactly. The viewing angle specification of 160° is provided for this substitute, offering additional optical performance data. All compliance certifications are maintained. Bulk packaging accommodates high-volume production requirements. This substitute offers enhanced brightness performance with reduced forward voltage characteristics.

Compliance Verification:

All three parts maintain Active product status, RoHS3 compliance, MSL 1 (Unlimited) rating, and REACH Unaffected status. No additional regulatory or environmental considerations differentiate the substitutes from the main part.

Frequently Asked Questions (FAQ)

Q: Can HLMP-2685 be used as a direct replacement for KB-H100SRW without circuit modification?

A: HLMP-2685 can be used as a direct replacement in most applications. The 0.15V forward voltage increase requires evaluation of the series resistor value in the LED circuit. If the original circuit was designed with adequate voltage margin, no modification is necessary. If circuit voltage is constrained, the series resistor should be recalculated using Ohm's law: R = (V_supply - V_forward) / I_forward.

Q: What is the brightness difference between KB-H100SRW and SSB-LXH100SRW?

A: SSB-LXH100SRW provides 150mcd compared to KB-H100SRW at 110mcd, representing a 36% increase in luminous intensity. This increased brightness may be advantageous in high-ambient-light environments or when enhanced visibility is required. The lower forward voltage (1.7V vs 1.85V) also reduces power consumption.

Q: Are there viewing angle differences between these parts?

A: KB-H100SRW and HLMP-2685 do not have specified viewing angle parameters in the provided data. SSB-LXH100SRW specifies a 160° viewing angle. All three parts share identical lens style (Rectangle with Flat Top), which determines the primary optical characteristics.

Q: What packaging considerations apply to each substitute?

A: KB-H100SRW is supplied with unspecified packaging. HLMP-2685 is supplied in Tube packaging, suitable for pick-and-place assembly equipment. SSB-LXH100SRW is supplied in Bulk packaging, suitable for high-volume manual or semi-automated assembly. Packaging selection should align with production assembly methods.

Q: Do all three parts meet the same regulatory requirements?

A: Yes. All three parts are RoHS3 Compliant, carry MSL 1 (Unlimited) rating, and are REACH Unaffected. No regulatory differentiation exists between the main part and substitutes.

Q: What wavelength differences exist, and do they affect color perception?

A: KB-H100SRW and SSB-LXH100SRW both operate at 660nm peak wavelength. HLMP-2685 operates at 634nm peak wavelength. Both wavelengths fall within the red spectrum classification. The 26nm difference may produce a slightly different red hue under direct observation, though both are classified as red indicators. Application-specific color matching requirements should be evaluated if critical.

Q: Can SSB-LXH100SRW replace KB-H100SRW in a current-limited circuit?

A: Yes. SSB-LXH100SRW operates at the same 30mA current rating as KB-H100SRW. The lower forward voltage (1.7V vs 1.85V) actually reduces power dissipation in the series resistor, improving circuit efficiency. No current limiting modifications are required.
