ELM 4-515 LED Standoff Equivalent & Substitute Parts

Part Overview

The ELM 4-515 is a T1 LED standoff manufactured by Bivar Inc., featuring a black PVC construction with a 0.515" (13.08mm) vertical mounting height. This component is classified as Active product status and is ROHS3 compliant. LED standoffs serve as mechanical spacers and alignment fixtures for T1 LED assemblies in electronic equipment, providing precise height control and vertical orientation during PCB assembly and integration. Substitute parts become necessary when the primary part experiences supply constraints, extended lead times, or when design flexibility permits minor dimensional variations within acceptable tolerances.

Substitute Part Grouping Explanation

Substitution eligibility for the ELM 4-515 is determined by the following critical parameters:

Primary Substitution Criteria:

• LED Type: T1 (fixed requirement)
• Material: Black PVC (fixed requirement)
• Manufacturer: Bivar Inc. (fixed requirement)
• Color: Black (fixed requirement)
• RoHS Status: ROHS3 Compliant (fixed requirement)
• Moisture Sensitivity Level: 1 (Unlimited) (fixed requirement)

Variable Parameter Allowing Substitution:

• Length: 0.515" (13.08mm) nominal, with acceptable variance to 0.510" (12.95mm) and 0.500" (12.70mm)

The ELM 2-510 and ELM 2-500 are classified as parametric equivalents because they maintain identical LED type, material composition, color, and compliance certifications while varying only in standoff length. These dimensional variations fall within the mechanical tolerance envelope for T1 LED standoff applications where precise height control permits minor deviations.

Engineering Selection Recommendations

ELM 4-515 Primary Selection: The ELM 4-515 remains the preferred component when design specifications require the 0.515" (13.08mm) standoff height. All three parts maintain Active product status with continuous manufacturing support from Bivar Inc.

ELM 2-510 Substitution: The ELM 2-510 provides a 0.005" (0.13mm) reduction in standoff height compared to the ELM 4-515. This substitute is suitable for applications where the LED vertical position tolerance permits a 0.13mm downward shift. Both parts share identical material, LED type, and compliance certifications.

ELM 2-500 Substitution: The ELM 2-500 provides a 0.015" (0.38mm) reduction in standoff height compared to the ELM 4-515. This substitute is suitable for applications where the LED vertical position tolerance permits a 0.38mm downward shift. Both parts share identical material, LED type, and compliance certifications.

All three parts are ROHS3 compliant with MSL 1 rating, indicating compatibility with standard storage and handling procedures without moisture sensitivity constraints.

Frequently Asked Questions (FAQ)

Q: What is the primary difference between ELM 4-515 and its substitutes?

A: The primary difference is standoff length. The ELM 4-515 measures 0.515" (13.08mm), while the ELM 2-510 measures 0.510" (12.95mm) and the ELM 2-500 measures 0.500" (12.70mm). All other parameters—LED type, material, color, and compliance—remain identical.

Q: Can ELM 2-510 and ELM 2-500 be used interchangeably with ELM 4-515?

A: Interchangeability depends on the application's tolerance for LED vertical position variation. If the design permits a 0.13mm or 0.38mm reduction in standoff height respectively, substitution is valid. If precise height control is critical, only the ELM 4-515 should be used.

Q: Are all three parts manufactured by the same company?

A: Yes, all three parts are manufactured by Bivar Inc. and share the same base product series designation (ELM 4 and ELM 2 series).

Q: Do these parts have different RoHS compliance levels?

A: No, all three parts are ROHS3 compliant with identical Moisture Sensitivity Level 1 (Unlimited) ratings.

Q: What is the inventory status of each part?

A: ELM 4-515 has 1034 pieces in stock, ELM 2-510 has 1846 pieces in stock, and ELM 2-500 has 4519 pieces in stock. All are listed as New Original In Stock.

Q: Are there any export or tariff considerations when selecting substitutes?

A: All three parts share ECCN classification EAR99. The ELM 4-515 and ELM 2-510/2-500 have different HTSUS codes (8547.20.0000 versus 3926.90.9985), which may affect tariff classification depending on import jurisdiction.
