ELM 4-615 LED Standoff Equivalent & Substitute Parts

Part Overview

The ELM 4-615 is a T1 LED standoff manufactured by Bivar Inc., designed for vertical mounting applications with a 0.615" (15.62mm) height. 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 are identified when equivalent functional performance can be achieved within the allowed mechanical and electrical parameter tolerances for T1 LED standoff applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ELM 4-615 is determined by strict adherence to the following parameters:

Critical Matching Parameters:

• Manufacturer: Bivar Inc. (same manufacturer ensures design consistency)
• LED Type: T1 (3mm package standard)
• Material: Black PVC (mechanical and thermal properties)
• Lead Configuration: 2LD (electrical connectivity requirement)
• Series: ELM 4 (product family compatibility)
• RoHS Status: ROHS3 Compliant (regulatory requirement)
• Moisture Sensitivity Level: MSL 1 (environmental tolerance)

Allowable Variation Parameter:

• Length: Mechanical height tolerance within the ELM 4 series design envelope

The ELM 4-600 qualifies as a parametric equivalent because it maintains all critical matching parameters while varying only in the length dimension (0.600" versus 0.615"). This length variation remains within the mechanical design tolerance of the ELM 4 series standoff family.

Engineering Selection Recommendations

Primary Selection Criteria:

The ELM 4-615 is the specified component and should be used when the 0.615" (15.62mm) standoff height is a design requirement. Both the main part and substitute maintain Active product status, ensuring availability and ongoing manufacturer support.

Substitute Selection Conditions:

The ELM 4-600 substitute part is electrically and mechanically compatible with the ELM 4-615 within the ELM 4 series design parameters. The 0.015" (0.38mm) height reduction represents a minor mechanical variation that does not affect the T1 LED package accommodation or two-lead electrical connectivity. Both parts carry identical ROHS3 compliance and MSL 1 ratings, confirming equivalent environmental performance.

Selection of the ELM 4-600 as a substitute is valid when the application design envelope permits the reduced standoff height, or when supply chain considerations necessitate alternative sourcing within the same manufacturer's product family.

Frequently Asked Questions (FAQ)

Q: Can the ELM 4-600 be used in place of the ELM 4-615?

A: The ELM 4-600 is a parametric equivalent within the Bivar Inc. ELM 4 series. Substitution is valid when the application design accommodates the 0.015" (0.38mm) reduction in standoff height. Both parts maintain identical electrical, material, and compliance specifications.

Q: What is the significance of the length difference between these parts?

A: The length parameter (0.615" versus 0.600") defines the vertical spacing between the PCB mounting surface and the LED package. This dimension affects board-level clearance and component positioning. The 0.015" variation must be evaluated against specific application layout requirements.

Q: Are both parts ROHS3 compliant?

A: Yes. Both the ELM 4-615 and ELM 4-600 carry ROHS3 compliance certification, confirming they meet current environmental and hazardous substance restrictions.

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

A: Moisture Sensitivity Level 1 indicates these PVC standoff components have no moisture sensitivity restrictions. They do not require special handling, storage, or baking procedures prior to assembly.

Q: Are both parts available in the same packaging format?

A: Yes. Both the ELM 4-615 and ELM 4-600 are supplied in Bag packaging, maintaining consistent handling and inventory management procedures.

Q: Can I mix ELM 4-615 and ELM 4-600 parts in the same production run?

A: Mixing is not recommended for applications where consistent standoff height is a design requirement. If height variation is acceptable within your application tolerance, both parts may be used; however, this should be explicitly documented in the design specification and assembly procedures.

Q: What is the base product number significance?

A: Both parts share the base product number ELM4-6, indicating they belong to the same fundamental product family within the ELM 4 series. The suffix digits (615 and 600) specify the length variant.
