ELM 5-425 LED Standoff Equivalent & Substitute Parts

Part Overview

The ELM 5-425 is a T1 LED standoff manufactured by Bivar Inc., designed for vertical mounting applications with a 0.425" (10.80mm) length. This component features a black PVC construction and accommodates 3MM LED configurations with 2-lead connections. The part maintains Active product status and is ROHS3 compliant with unlimited moisture sensitivity rating (MSL 1).

Substitute parts are identified when design requirements permit variations in specific mechanical dimensions while maintaining functional compatibility within the T1 LED standoff category and material specifications.

Key Parameters

Substitute Part Grouping Explanation

The ELM 5-425 has one identified parametric equivalent: ELM 4-440. Substitution eligibility is determined by the following criteria:

Substitution-Determining Parameters:

• LED Type: T1 (must match)
• Material: Black PVC (must match)
• Configuration: Vertical Mount, 3MM, 2-Lead (must match)
• Manufacturer: Bivar Inc. (must match)
• Product Status: Active (must match)
• RoHS Compliance: ROHS3 Compliant (must match)
• Moisture Sensitivity Level: 1 (Unlimited) (must match)

Variable Parameter:

• Length: 0.425" (10.80mm) for ELM 5-425 versus 0.440" (11.18mm) for ELM 4-440

The ELM 4-440 substitute differs only in standoff length by 0.015" (0.38mm). This dimensional variation permits substitution in applications where the increased standoff height is mechanically compatible with the circuit board layout and component clearance requirements.

Parameter Comparison

Engineering Selection Recommendations

Both the ELM 5-425 and ELM 4-440 maintain Active product status with identical ROHS3 compliance and unlimited moisture sensitivity ratings. Selection between these parts is determined by mechanical fit requirements within the target application.

The ELM 5-425 provides a 0.425" standoff height suitable for standard PCB clearance applications. The ELM 4-440 substitute offers a 0.015" greater standoff height (0.440"), accommodating applications requiring additional vertical clearance between the LED and circuit board surface.

Both parts are manufactured by Bivar Inc. using identical material composition (Black PVC) and support the same T1 LED configuration with 2-lead vertical mounting. Compliance certifications and export classifications (ECCN EAR99, HTSUS 3926.90.9985) are equivalent across both parts.

Frequently Asked Questions (FAQ)

Q: Can the ELM 4-440 directly replace the ELM 5-425 in all applications?

A: The ELM 4-440 substitute differs in standoff length by 0.015" (0.38mm). Direct replacement is possible only in applications where this increased height does not conflict with PCB layout, component clearance, or mechanical assembly constraints. Verify dimensional compatibility within your specific circuit board design before substitution.

Q: Are there material or electrical differences between these parts?

A: No. Both parts use identical Black PVC material composition and support the same T1 LED configuration with 2-lead vertical mounting. Electrical and material specifications are equivalent.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the ELM 5-425 and ELM 4-440 are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating. Export classification (ECCN EAR99) and tariff codes (HTSUS 3926.90.9985) are identical.

Q: What is the primary substitution criterion between these parts?

A: Standoff length is the only variable parameter. The ELM 4-440 provides 0.440" height compared to the ELM 5-425 at 0.425". All other specifications—LED type, material, configuration, manufacturer, and compliance certifications—are identical.

Q: Are both parts currently available?

A: Yes. Both parts maintain Active product status. Current inventory includes 885 pieces of ELM 5-425 and 991 pieces of ELM 4-440 in new original condition.
