ELM 5-3MM LED Standoff Equivalent & Substitute Parts

Part Overview

The ELM 5-3MM is a T1 LED standoff manufactured by Bivar Inc., designed for vertical mounting applications with a 0.120" (3.05mm) length. This component is an active product with ROHS3 compliance and MSL Level 1 rating. Substitute parts may be required due to inventory constraints, design revisions, or application-specific mechanical tolerances that fall within acceptable parametric ranges.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ELM 5-3MM is determined by the following critical parameters:

Primary Matching Criteria:

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

Secondary Tolerance Parameter:

• Length: 0.120" ± 0.005" (3.05mm ± 0.127mm) mechanical tolerance allowance

The substitute parts ELM 2-120 and ELM 4-115 meet all primary criteria. ELM 2-120 matches the exact length specification. ELM 4-115 operates within acceptable mechanical tolerance for applications where 0.115" (2.92mm) length is functionally equivalent to the nominal 0.120" specification.

Parameter Comparison

Engineering Selection Recommendations

ELM 2-120 Selection Criteria:

• Identical length specification (0.120" / 3.05mm)
• All primary parameters match exactly
• Active product status with ROHS3 compliance
• Highest inventory availability (86,435 pcs)
• Suitable for direct replacement in applications requiring exact dimensional match

ELM 4-115 Selection Criteria:

• Length variance of 0.005" (0.13mm) below nominal specification
• All primary parameters match exactly
• Active product status with ROHS3 compliance
• Moderate inventory availability (1,684 pcs)
• Suitable for applications where 0.115" mounting height is functionally acceptable within design tolerance

Both substitute parts maintain identical electrical and environmental compliance characteristics as the main part.

Frequently Asked Questions (FAQ)

Q: Can ELM 2-120 be used as a direct replacement for ELM 5-3MM?

A: Yes. ELM 2-120 matches all critical parameters including LED type (T1), material (PVC), color (Black), mounting style (Vertical), and length (0.120" / 3.05mm). Both parts are ROHS3 compliant with MSL Level 1 rating.

Q: What is the length difference between ELM 4-115 and ELM 5-3MM?

A: ELM 4-115 is 0.005" (0.127mm) shorter than ELM 5-3MM. The main part measures 0.120" (3.05mm) while the substitute measures 0.115" (2.92mm). This difference falls within standard mechanical tolerances for T1 LED standoff applications.

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

A: Yes. ELM 5-3MM, ELM 2-120, and ELM 4-115 are all manufactured by Bivar Inc.

Q: Do the substitute parts have the same RoHS and MSL ratings?

A: Yes. All three parts are ROHS3 compliant and carry MSL Level 1 (Unlimited) ratings, indicating identical environmental compliance and moisture sensitivity characteristics.

Q: Which substitute part should be selected for space-constrained applications?

A: ELM 4-115 provides a 0.005" reduction in mounting height. Selection depends on whether the application design tolerance accommodates the shorter length specification.

Q: What is the packaging format for these parts?

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