ELM 4-665 LED Standoff Equivalent & Substitute Parts

Part Overview

The ELM 4-665 is a T1 LED standoff manufactured by Bivar Inc., designed for vertical mounting applications with a 0.665" (16.89mm) length. This component is an active product with full RoHS3 compliance and MSL Level 1 rating, indicating unlimited moisture tolerance. Substitute parts are identified when inventory constraints, series discontinuation, or specific application requirements necessitate alternative component selection while maintaining functional equivalence.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ELM 4-665 is determined by the following critical parameters:

Primary Substitution Criteria:

• LED Type: T1 (exact match required)
• Material: PVC (exact match required)
• Color: Black (exact match required)
• Mounting Style: Vertical (exact match required)
• Lead Count: 2 LD (exact match required)
• RoHS Compliance: ROHS3 Compliant (minimum requirement)
• MSL Rating: 1 (Unlimited) (minimum requirement)

Length Tolerance:

• Exact length match: 0.665" (16.89mm)
• Near-equivalent length: 0.670" (17.02mm) — acceptable for applications with ±0.005" tolerance

The ELM 2-665 provides direct parametric equivalence across all critical dimensions and certifications. The ELM 2-17MM offers functional substitution with a minor length variance of +0.005" (0.13mm), suitable for applications where this tolerance is acceptable.

Parameter Comparison

Engineering Selection Recommendations

ELM 2-665 Selection: The ELM 2-665 is the primary substitute for the ELM 4-665. Both parts maintain identical dimensional specifications (0.665" length), material composition (PVC), and all electrical/mechanical parameters. Both are active products with ROHS3 compliance and MSL Level 1 rating. Selection of ELM 2-665 is appropriate when ELM 4-665 inventory is unavailable and dimensional precision is critical.

ELM 2-17MM Selection: The ELM 2-17MM is a secondary substitute with a length of 0.670" (17.02mm), representing a +0.005" (0.13mm) increase from the main part specification. This substitute is suitable only for applications where the assembly design accommodates this length variance. Both parts share identical material, LED type, color, and compliance certifications. Selection of ELM 2-17MM requires confirmation that the additional 0.005" length does not impact PCB clearance, housing fit, or functional performance.

Frequently Asked Questions (FAQ)

Q: Can ELM 2-665 be used as a direct replacement for ELM 4-665?

A: Yes. The ELM 2-665 is a direct parametric equivalent. Both parts are identical in length (0.665"), material (PVC), LED type (T1), color (Black), and all compliance certifications (ROHS3, MSL 1). The only difference is the series designation (ELM 2 vs. ELM 4).

Q: What is the length difference between ELM 4-665 and ELM 2-17MM?

A: The ELM 2-17MM is 0.005" (0.13mm) longer than the ELM 4-665. The ELM 4-665 measures 0.665" (16.89mm), while the ELM 2-17MM measures 0.670" (17.02mm). This variance must be evaluated against specific application requirements.

Q: Are all three parts RoHS3 compliant?

A: Yes. The ELM 4-665, ELM 2-665, and ELM 2-17MM are all ROHS3 compliant with MSL Level 1 (Unlimited) moisture sensitivity rating.

Q: Which substitute should be selected if length tolerance is critical?

A: The ELM 2-665 should be selected for applications requiring exact length matching at 0.665" (16.89mm). The ELM 2-17MM introduces a +0.005" length variance and is suitable only when this tolerance is acceptable to the application design.

Q: Are packaging specifications identical across all three parts?

A: Yes. All three parts are supplied in Bag packaging format.

Q: Can ELM 2-17MM be used in applications designed for 0.665" standoff height?

A: The ELM 2-17MM can be used only if the application design accommodates the additional 0.005" (0.13mm) height. PCB clearance, housing fit, and mechanical constraints must be verified before substitution.
