HLMP2685 LED Circuit Board Indicator Bar Equivalent & Substitute Parts

Part Overview

The HLMP2685 is a red LED circuit board indicator bar manufactured by onsemi, featuring a single DIP configuration with a 19.05mm x 8.89mm rectangular flat-top lens. This through-hole mounted component operates at 2V with 90mA current and delivers 80mcd brightness. The part is currently obsolete, making equivalent and substitute parts necessary for ongoing design requirements and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the HLMP2685 is determined by the following critical parameters:

• Configuration: Bar - Single, DIP (single LED element in DIP package)
• Lens Size: 19.05mm x 8.89mm (physical footprint and mounting compatibility)
• Lens Style: Rectangle with Flat Top (optical and mechanical form factor)
• Mounting Type: Through Hole (PCB assembly method)
• Color: Red (wavelength range 625nm–645nm acceptable)
• Voltage Rating: 2V nominal operation
• Current: Operating current range 20mA–100mA
• Millicandela Rating: 16mcd–80mcd brightness range

Substitute parts must maintain identical lens dimensions, mounting type, and DIP configuration to ensure direct PCB footprint compatibility. Voltage and current parameters may vary within acceptable operating ranges for the application circuit. Wavelength variations within the red spectrum (625nm–645nm) are acceptable for general indicator applications.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent (Highest Compatibility): The HLMP-2685 manufactured by Broadcom Limited is the primary direct equivalent. It maintains identical lens dimensions (19.05mm x 8.89mm), configuration (Bar - Single, DIP), voltage rating (2V), and millicandela rating (80mcd). The part is currently active with ROHS3 compliance and REACH unaffected status, ensuring regulatory compliance and supply continuity.

Compatible Substitutes (Same Footprint, Parameter Variations): KB2685EW (Kingbright) and LTL-2685HR (Lite-On) maintain identical lens dimensions and mounting configuration. Both are active products with ROHS3 compliance. KB2685EW operates at 30mA with 40mcd brightness and features a diffused white lens. LTL-2685HR operates at 100mA with 16mcd brightness and diffused lens. These parts require circuit design verification due to current and brightness variations.

Not Recommended: HLCP-H100 (Broadcom) features different lens dimensions (0.8" x 0.4") and lower voltage rating (1.8V), making it incompatible with the original HLMP2685 footprint and circuit requirements.

Frequently Asked Questions (FAQ)

Q: Can HLMP-2685 (Broadcom) directly replace HLMP2685 (onsemi)? A: Yes. Both parts share identical lens dimensions (19.05mm x 8.89mm), DIP configuration, 2V voltage rating, and 80mcd brightness. The Broadcom part is currently active and ROHS3 compliant, providing direct PCB compatibility and electrical equivalence.

Q: What are the key differences between KB2685EW and the original HLMP2685? A: KB2685EW maintains the same lens size and mounting type but operates at 30mA (versus 90mA) with 40mcd brightness (versus 80mcd). The lens features diffused white coating. Circuit design must accommodate the lower current draw and reduced brightness output.

Q: Is LTL-2685HR a suitable replacement? A: LTL-2685HR maintains identical lens dimensions and mounting configuration. However, it operates at 100mA with only 16mcd brightness and features a diffused lens. This part is suitable only if the application tolerates significantly reduced brightness and higher current consumption. REACH status is affected, requiring compliance verification.

Q: Why is HLCP-H100 not recommended as a substitute? A: HLCP-H100 features different lens dimensions (0.8" x 0.4" versus 19.05mm x 8.89mm) and lower voltage rating (1.8V versus 2V). These differences prevent direct PCB footprint compatibility and require circuit redesign.

Q: What compliance certifications should I verify for production use? A: All recommended substitutes maintain MSL 1 (Unlimited) moisture sensitivity and REACH unaffected status, except LTL-2685HR which is REACH affected. All active substitutes are ROHS3 compliant. Verify REACH compliance requirements for your specific application and target markets.

Q: Can I use multiple substitute parts interchangeably in the same design? A: No. HLMP-2685 (Broadcom) is the only direct equivalent. KB2685EW and LTL-2685HR require individual circuit design verification due to current and brightness variations. Select one substitute part and validate circuit performance before production implementation.
