HLMP2500 LED Indicator Bar - Equivalent & Substitute Parts

Part Overview

The HLMP2500 is a green LED circuit board indicator bar manufactured by onsemi, featuring a single SIP configuration with an 8.89mm x 3.81mm rectangular flat-top lens. This component is classified as obsolete, making identification of suitable substitute parts essential for ongoing design support and production continuity. The part operates at 2.2V with a 90mA current rating and delivers 25mcd luminous intensity at a peak wavelength of 565nm. Due to its obsolete status, equivalent alternatives from active manufacturers are necessary for new designs and component replenishment.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HLMP2500 is determined by the following critical parameters:

Primary Compatibility Criteria:

• Color: Green (565nm peak wavelength)
• Lens Size: 8.89mm x 3.81mm
• Lens Style: Rectangle with Flat Top
• Mounting Type: Through Hole
• Voltage Rating: 2.2V nominal (±0.1V tolerance acceptable)

Secondary Considerations:

• Configuration: Bar - Single format (SIP or DIP acceptable)
• Current Rating: Substitute parts must operate within the design's current-limiting circuit
• Millicandela Rating: Luminous intensity must meet or exceed application requirements

The identified substitute parts HLMP-2500 (Broadcom Limited) and LTL-2500G (Lite-On Inc.) satisfy the primary compatibility criteria. Both maintain identical lens dimensions, mounting configuration, and optical wavelength specifications. Variations in current rating and millicandela output reflect different LED die designs but do not preclude functional substitution when circuit design accommodates the electrical differences.

Parameter Comparison

Engineering Selection Recommendations

HLMP-2500 (Broadcom Limited) is the primary substitute for the HLMP2500. This part maintains identical SIP configuration, lens geometry, and optical specifications. The reduced current rating of 30mA versus the original 90mA requires circuit verification to ensure the current-limiting resistor accommodates the lower operating point. The part is active in production with ROHS3 compliance, providing long-term availability and regulatory alignment.

LTL-2500G (Lite-On Inc.) serves as an alternative substitute with the following considerations: The DIP configuration differs from the original SIP format, requiring PCB layout modification. The millicandela rating of 4.2mcd is significantly lower than the original 25mcd specification, making this option suitable only for applications where reduced brightness is acceptable. The voltage rating of 2.1V is within acceptable tolerance of the 2.2V specification. This part is active in production with ROHS3 compliance.

Both substitute parts carry MSL 1 (Unlimited) moisture sensitivity ratings, matching the original component's environmental specifications. Selection between HLMP-2500 and LTL-2500G depends on circuit design flexibility regarding current draw and brightness requirements, as well as PCB layout constraints related to SIP versus DIP mounting.

Frequently Asked Questions (FAQ)

Q: Can the HLMP-2500 (Broadcom) be used as a direct replacement for the HLMP2500 (onsemi)?

A: The HLMP-2500 maintains identical physical dimensions, lens configuration, and optical wavelength. The primary difference is the reduced current rating (30mA versus 90mA). Direct substitution is possible if the circuit's current-limiting resistor is verified to operate correctly at the lower current level. No PCB layout changes are required.

Q: What are the key differences between the HLMP-2500 and LTL-2500G?

A: The HLMP-2500 uses SIP configuration while the LTL-2500G uses DIP configuration, requiring different PCB footprints. The LTL-2500G has a significantly lower millicandela rating (4.2mcd versus 25mcd), resulting in reduced brightness. The voltage ratings differ slightly (2.2V versus 2.1V), which is within acceptable tolerance. Current ratings also differ (30mA versus 100mA).

Q: Is the LTL-2500G suitable for applications requiring high brightness?

A: No. The LTL-2500G's millicandela rating of 4.2mcd is substantially lower than the original HLMP2500 specification of 25mcd. This part is suitable only for applications where reduced luminous intensity is acceptable or where the design can accommodate increased current draw to compensate for lower efficiency.

Q: Are both substitute parts RoHS compliant?

A: Yes. Both the HLMP-2500 (Broadcom) and LTL-2500G (Lite-On) are ROHS3 compliant, meeting current environmental and regulatory requirements.

Q: What is the moisture sensitivity level for these parts?

A: All three parts—the original HLMP2500 and both substitutes—carry MSL 1 (Unlimited) ratings, indicating no moisture sensitivity restrictions for storage or handling.

Q: Can I use the LTL-2500G without modifying my PCB?

A: No. The LTL-2500G uses DIP configuration while the original HLMP2500 uses SIP configuration. These configurations have different pin arrangements and footprints, requiring PCB layout modification.
