ELM 4-675 LED Standoff Equivalent & Substitute Parts

Part Overview

The ELM 4-675 is a T1 LED standoff manufactured by Bivar Inc., designed for vertical mounting applications with a 0.675" (17.15mm) length. This component is constructed from black PVC material and accommodates 3MM LED packages with 2-lead configurations. The part maintains Active product status and is RoHS3 compliant, making it suitable for current production environments.

Substitute parts become necessary when the primary part experiences inventory constraints, extended lead times, or when design flexibility permits minor dimensional variations within acceptable tolerances. The ELM 4-675 has identified equivalent alternatives within the Bivar Inc. product portfolio that maintain functional compatibility through parametric equivalence.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ELM 4-675 is determined by the following critical parameters:

Primary Compatibility Criteria:

• LED Type: T1 (fixed requirement)
• Material: Black PVC (fixed requirement)
• LED Package Size: 3MM (fixed requirement)
• Lead Configuration: 2-Lead (fixed requirement)
• Mounting Orientation: Vertical (fixed requirement)
• RoHS Compliance: ROHS3 Compliant (fixed requirement)

Allowable Variation:

• Length: Dimensional tolerance within 0.675" ± 0.010" (17.15mm ± 0.25mm) permits substitution of parts with lengths of 0.665" (16.89mm) and 0.670" (17.02mm)

Both identified substitute parts—ELM 2-665 and ELM 2-17MM—satisfy all primary compatibility criteria and fall within the acceptable length tolerance band. Both maintain Active product status and ROHS3 compliance.

Parameter Comparison

Engineering Selection Recommendations

ELM 2-665 Selection Criteria: The ELM 2-665 operates as a direct parametric equivalent with a length of 0.665" (16.89mm), representing a -0.010" variance from the ELM 4-675 specification. This part maintains identical material composition, LED type, package size, and lead configuration. Product status is Active with ROHS3 compliance and MSL 1 rating. Current inventory availability is 882 pieces.

ELM 2-17MM Selection Criteria: The ELM 2-17MM functions as a parametric equivalent with a length of 0.670" (17.02mm), representing a -0.005" variance from the ELM 4-675 specification. This part maintains identical material composition, LED type, package size, and lead configuration. Product status is Active with ROHS3 compliance and MSL 1 rating. Current inventory availability is 1815 pieces.

Both substitutes are suitable for applications where the ELM 4-675 experiences supply constraints. Selection between ELM 2-665 and ELM 2-17MM should be based on dimensional tolerance requirements specific to the application, with ELM 2-17MM offering closer dimensional alignment to the original specification.

Frequently Asked Questions (FAQ)

Q: What determines whether ELM 2-665 or ELM 2-17MM can substitute for ELM 4-675?

A: Substitution is determined by matching LED type (T1), material (Black PVC), LED package size (3MM), lead configuration (2-Lead), mounting orientation (Vertical), and RoHS compliance (ROHS3). Length variations of ±0.010" are within acceptable tolerance for this product category.

Q: What is the maximum length difference between the main part and substitutes?

A: ELM 2-665 has a maximum variance of -0.010" (0.26mm) from the ELM 4-675 specification. ELM 2-17MM has a maximum variance of -0.005" (0.13mm). Both fall within the allowable tolerance band for this application.

Q: Are all three parts packaged identically?

A: Yes. The ELM 4-675, ELM 2-665, and ELM 2-17MM are all supplied in Bag packaging.

Q: Do the substitute parts maintain the same moisture sensitivity rating?

A: Yes. All three parts carry Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity constraints during storage or handling.

Q: Which substitute part has better inventory availability?

A: ELM 2-17MM has 1815 pieces in stock, compared to 882 pieces for ELM 2-665. The main part ELM 4-675 has 960 pieces available.

Q: Are there any compliance differences between the main part and substitutes?

A: All three parts are ROHS3 compliant. ELM 2-665 carries additional REACH Unaffected status. Both substitutes maintain identical ECCN (EAR99) classification.
