ELM 4-350 Equivalent & Substitute Parts

Part Overview

The ELM 4-350 is a T1 LED standoff manufactured by Bivar Inc., designed for vertical mounting applications. This component features a black PVC construction with a 0.350" (8.89mm) length and accommodates T1 LED packages with 2-lead configuration. The part is Active in product status and maintains full RoHS3 compliance. Substitute parts are identified to address inventory availability, supply chain continuity, or specific application requirements while maintaining functional equivalence within defined electrical and mechanical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ELM 4-350 is determined by the following critical parameters:

Primary Equivalence Criteria:

• LED Type: T1 (fixed requirement)
• Material: Black PVC (fixed requirement)
• Lead Configuration: 2-Lead (fixed requirement)
• Mounting Orientation: Vertical (fixed requirement)
• RoHS Compliance: ROHS3 Compliant (fixed requirement)
• Moisture Sensitivity Level: 1 (Unlimited) (fixed requirement)

Variable Parameters Allowing Substitution:

• Length: 0.350" (8.89mm) or 0.365" (9.27mm)
• Series: ELM 4 or ELM 2

The identified substitute parts (ELM 2-350 and ELM 2-365) maintain all primary equivalence criteria while varying in series designation and, in one case, length specification. Both substitutes are manufactured by Bivar Inc. and retain Active product status with full RoHS3 compliance.

Parameter Comparison

Engineering Selection Recommendations

ELM 2-350 Selection Criteria: The ELM 2-350 provides direct dimensional equivalence to the ELM 4-350, maintaining identical 0.350" (8.89mm) length specification. Both parts share identical electrical and mechanical characteristics, including T1 LED accommodation, black PVC construction, and 2-lead vertical mounting configuration. Both maintain Active product status and full ROHS3 compliance. This substitute is suitable for applications where the ELM 4-350 is unavailable and dimensional precision at 0.350" is required.

ELM 2-365 Selection Criteria: The ELM 2-365 differs from the ELM 4-350 in length specification, measuring 0.365" (9.27mm) compared to 0.350" (8.89mm). This 0.015" (0.38mm) dimensional variance must be evaluated against specific application mounting clearances and PCB layout constraints. The ELM 2-365 maintains all other electrical and mechanical equivalence parameters, including T1 LED type, black PVC material, 2-lead configuration, vertical orientation, and ROHS3 compliance. This substitute is applicable only when the increased length does not conflict with design specifications.

Both substitutes are manufactured by Bivar Inc. and carry Active product status with unlimited moisture sensitivity rating (MSL 1).

Frequently Asked Questions (FAQ)

Q: Can ELM 2-350 directly replace ELM 4-350 without design modification?

A: Yes. The ELM 2-350 maintains identical length (0.350" / 8.89mm), LED type (T1), material (black PVC), lead configuration (2-lead), mounting orientation (vertical), and compliance status (ROHS3). No design modification is required for dimensional or electrical compatibility.

Q: What is the key difference between ELM 2-365 and ELM 4-350?

A: The primary difference is length. ELM 2-365 measures 0.365" (9.27mm) versus ELM 4-350 at 0.350" (8.89mm), a 0.015" (0.38mm) increase. All other parameters—LED type, material, lead configuration, mounting orientation, and compliance—remain equivalent.

Q: Is ELM 2-365 suitable for applications requiring exact 0.350" length?

A: No. The ELM 2-365 length specification of 0.365" (9.27mm) exceeds the 0.350" (8.89mm) requirement. Use of this substitute requires confirmation that the additional 0.015" (0.38mm) does not violate PCB clearance, mounting height, or assembly constraints.

Q: Are all three parts (ELM 4-350, ELM 2-350, ELM 2-365) RoHS compliant?

A: Yes. All three parts maintain ROHS3 compliance and carry Moisture Sensitivity Level 1 (Unlimited), indicating no moisture-related handling restrictions.

Q: What is the inventory status of substitute parts?

A: ELM 2-350 has 3,507 pieces in stock. ELM 2-365 has 16,125 pieces in stock. Both are available as new original components.

Q: Can ELM 4-350 and ELM 2-series parts be used interchangeably in the same assembly?

A: ELM 2-350 and ELM 4-350 are interchangeable without modification. ELM 2-365 is interchangeable only if the 0.365" length does not conflict with design specifications. All three maintain identical electrical characteristics and compliance requirements.
