ELM 2-520 LED Standoff Equivalent & Substitute Parts

Part Overview

The ELM 2-520 is a T1 LED standoff manufactured by Bivar Inc., featuring a black PVC construction with a 0.520" (13.21mm) vertical mounting height. This component is classified as an active product and is ROHS3 compliant. LED standoffs serve as mechanical spacers and alignment fixtures in electronic assemblies, positioning light-emitting diodes at precise heights above printed circuit boards. Substitute parts become necessary when the primary part experiences supply constraints, extended lead times, or when design specifications permit tolerance variations in standoff height.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ELM 2-520 is determined by the following parameters:

Primary Substitution Criteria:

• Manufacturer: Bivar Inc. (same manufacturer ensures design compatibility)
• Series: ELM 2 (same product family)
• LED Type: T1 (identical LED form factor)
• Material: Black PVC (identical material composition)
• Color: Black (identical color specification)
• RoHS Status: ROHS3 Compliant (regulatory compliance maintained)
• Moisture Sensitivity Level: 1 (Unlimited) (identical MSL rating)

Variable Parameter:

• Length (Height): Tolerance range permits substitution within the ELM 2 series standoff heights

The ELM 2-510 and ELM 2-500 are classified as parametric equivalents because they maintain all critical parameters except for standoff height, which varies by 0.010" and 0.020" respectively from the primary part specification.

Parameter Comparison

Engineering Selection Recommendations

All three parts—ELM 2-520, ELM 2-510, and ELM 2-500—maintain active product status and ROHS3 compliance, ensuring regulatory and supply chain continuity. Selection between these parts depends on mechanical height tolerance requirements within the assembly design.

ELM 2-520 is the primary specification when exact 0.520" (13.21mm) standoff height is required.

ELM 2-510 serves as a substitute when a 0.010" (0.25mm) height reduction is acceptable within design tolerances.

ELM 2-500 serves as a substitute when a 0.020" (0.51mm) height reduction is acceptable within design tolerances.

All substitute parts are manufactured by Bivar Inc. within the same ELM 2 series, ensuring mechanical and electrical compatibility with T1 LED form factors. Inventory availability varies across the three options, with ELM 2-500 showing the highest stock level at 4519 pieces.

Frequently Asked Questions (FAQ)

Q: What is the primary difference between ELM 2-520, ELM 2-510, and ELM 2-500?

A: The three parts are identical in all specifications except standoff height. ELM 2-520 measures 0.520" (13.21mm), ELM 2-510 measures 0.510" (12.95mm), and ELM 2-500 measures 0.500" (12.70mm). All other parameters—LED type, material, color, RoHS compliance, and MSL rating—are identical.

Q: Can ELM 2-510 or ELM 2-500 be used as direct replacements for ELM 2-520?

A: Substitution is possible only if the design specification permits height tolerance variations. The height differences are 0.010" and 0.020" respectively. Design documentation must confirm that these height reductions do not affect circuit board clearance, LED alignment, or optical performance.

Q: Are all three parts ROHS3 compliant?

A: Yes. ELM 2-520, ELM 2-510, and ELM 2-500 are all ROHS3 compliant with MSL rating of 1 (Unlimited), ensuring regulatory compliance and unlimited shelf life without moisture sensitivity concerns.

Q: What is the packaging format for these parts?

A: All three parts are supplied in bag packaging, suitable for bulk component handling and automated assembly processes.

Q: Which part has the best inventory availability?

A: ELM 2-500 has the highest inventory level at 4519 pieces in stock. ELM 2-510 has 1846 pieces, and ELM 2-520 has 617 pieces available.

Q: Are these parts from the same manufacturer?

A: Yes. All three parts are manufactured by Bivar Inc. and belong to the ELM 2 series, ensuring design consistency and supply chain reliability.
