ELM 4-10MM LED Standoff Equivalent & Substitute Parts

Part Overview

The ELM 4-10MM is an active T1 LED standoff manufactured by Bivar Inc., constructed from black PVC material with a 0.390" (9.91mm) length. This component functions as a vertical mounting standoff for T1 LED assemblies in 3MM and 2-lead configurations. The part is ROHS3 compliant and maintains unlimited moisture sensitivity rating (MSL 1). Substitute parts are identified when equivalent electrical and mechanical parameters align with the original specification, enabling direct functional replacement in applications where the primary part becomes unavailable or inventory constraints require alternative sourcing.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ELM 4-10MM is determined by strict alignment of the following parameters:

Primary Matching Criteria:

• LED Type: T1 (form factor compatibility)
• Lead Configuration: 2-Lead (electrical connection)
• Color: Black (visual specification)
• RoHS Status: ROHS3 Compliant (regulatory requirement)
• MSL Rating: 1 (Unlimited) (environmental tolerance)

Secondary Consideration:

• Length: 0.390" (9.91mm) nominal, with tolerance of ±0.010" (0.254mm) acceptable for mechanical fit

Two substitute parts meet these criteria: ELM 5-390 and H-201C. Both maintain identical LED type, lead configuration, color specification, and compliance certifications. ELM 5-390 matches the exact length specification. H-201C operates within acceptable length tolerance (0.380" vs. 0.390") while substituting nylon material for PVC, which does not affect functional compatibility in standard LED mounting applications.

Parameter Comparison

Engineering Selection Recommendations

ELM 5-390 Selection Criteria: ELM 5-390 is the primary parametric equivalent to ELM 4-10MM. Both parts share identical specifications across all critical parameters: T1 LED type, 0.390" length, PVC material composition, black color, 2-lead configuration, and ROHS3 compliance. Selection of ELM 5-390 introduces no dimensional or material variance and maintains full functional equivalence. This part is suitable for direct substitution in all applications where ELM 4-10MM is specified.

H-201C Selection Criteria: H-201C functions as a compatible substitute with a single material variance (nylon vs. PVC) and a minor length differential (0.380" vs. 0.390"). The 0.010" (0.254mm) length reduction falls within standard mechanical tolerance ranges for LED standoff applications. Nylon material maintains equivalent mechanical strength and environmental resistance for standard mounting conditions. H-201C is suitable for substitution when material flexibility is acceptable and the reduced standoff height does not conflict with PCB layout constraints.

Both substitute parts maintain active product status and full regulatory compliance (ROHS3, REACH Unaffected, EAR99 ECCN classification).

Frequently Asked Questions (FAQ)

Q: Can ELM 5-390 be used as a direct replacement for ELM 4-10MM?

A: Yes. ELM 5-390 matches all critical parameters of ELM 4-10MM, including LED type (T1), length (0.390"), material (PVC), color (black), lead configuration (2-lead), and regulatory compliance (ROHS3). Direct substitution is supported without design modification.

Q: What is the functional difference between ELM 4-10MM and H-201C?

A: The primary difference is material composition: ELM 4-10MM uses PVC while H-201C uses nylon. Additionally, H-201C has a length of 0.380" compared to ELM 4-10MM's 0.390", a 0.010" reduction. Both materials provide equivalent mechanical and environmental performance for standard LED mounting applications. The length difference must be evaluated against specific PCB clearance requirements.

Q: Are all three parts (ELM 4-10MM, ELM 5-390, H-201C) ROHS3 compliant?

A: Yes. All three parts carry ROHS3 compliance certification and REACH Unaffected status, meeting current regulatory requirements for electronic component manufacturing and distribution.

Q: What does MSL 1 (Unlimited) mean for these parts?

A: MSL 1 (Unlimited) indicates that these components have no moisture sensitivity restrictions. They can be stored and handled under standard environmental conditions without requiring specialized moisture-controlled packaging or shelf-life limitations.

Q: Can H-201C be substituted in applications where exact height is critical?

A: H-201C's 0.010" shorter length may affect applications with strict vertical clearance specifications. Verify that the reduced standoff height (0.380" vs. 0.390") does not conflict with PCB layout, component spacing, or assembly constraints before substitution.

Q: Are ELM 4-10MM and ELM 5-390 from the same manufacturer?

A: Yes. Both parts are manufactured by Bivar Inc. and belong to the same product family (ELM series), with ELM 5-390 representing an alternative series designation within the same manufacturer's portfolio.
