ELM 4-135 LED Standoff Equivalent & Substitute Parts

Part Overview

The ELM 4-135 is a T1 LED standoff manufactured by Bivar Inc., designed for vertical mounting applications with a 0.135" (3.43mm) height. This component is constructed from black PVC material and accommodates 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 electrical and mechanical parameters align within the allowed specifications for this product category, enabling component interchangeability in applications where dimensional and material tolerances permit.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ELM 4-135 is determined by the following critical parameters:

Primary Compatibility Criteria:

• LED Type: T1 (fixed requirement)
• Material: PVC (fixed requirement)
• Color: Black (fixed requirement)
• Lead Configuration: 2LD (fixed requirement)
• RoHS Status: ROHS3 Compliant (fixed requirement)
• Moisture Sensitivity Level: 1 (fixed requirement)

Variable Parameter:

• Length: Tolerance range permits variation within mechanical assembly constraints

The ELM 5-130 qualifies as a parametric equivalent because it maintains identical specifications across all primary compatibility criteria. The length differential of 0.005" (0.13mm) falls within acceptable mechanical tolerances for vertical standoff applications where minor height variations do not compromise circuit board assembly or component clearance requirements.

Engineering Selection Recommendations

ELM 4-135 Primary Selection: The ELM 4-135 is the specified component for applications requiring the 0.135" (3.43mm) standoff height. Active product status ensures ongoing manufacturing support and supply chain availability. ROHS3 compliance and MSL 1 rating confirm suitability for standard production and storage conditions without special handling requirements.

ELM 5-130 Substitute Selection: The ELM 5-130 serves as an equivalent substitute when the 0.130" (3.30mm) height accommodates circuit board design constraints. Both parts share identical material composition, lead configuration, and compliance certifications. Selection between these parts depends solely on mechanical height requirements within the assembly design.

Both parts maintain Active product status and equivalent compliance profiles, supporting interchangeability decisions based on dimensional fit within the target application.

Frequently Asked Questions (FAQ)

Q: What determines whether ELM 5-130 can substitute for ELM 4-135?

A: Substitution is valid when the 0.005" (0.13mm) height difference between the parts does not violate circuit board clearance specifications, component spacing requirements, or mechanical assembly constraints. Both parts are identical in all other functional and compliance parameters.

Q: Are there electrical performance differences between these parts?

A: No. Both the ELM 4-135 and ELM 5-130 are mechanical standoff components with identical T1 LED accommodation, lead configuration, and material properties. Electrical performance is determined by the LED component mounted on the standoff, not the standoff itself.

Q: Do both parts require identical storage and handling procedures?

A: Yes. Both parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions. Standard component storage in controlled environments is sufficient for both the ELM 4-135 and ELM 5-130.

Q: Can these parts be used interchangeably in existing production?

A: Interchangeability depends on mechanical design tolerance. If the circuit board assembly design specifies a height range that accommodates both 0.135" and 0.130" standoffs, substitution is permissible. Design documentation must confirm dimensional compatibility before implementation.

Q: What is the inventory status for each part?

A: ELM 4-135 maintains 1070 pieces in stock. ELM 5-130 maintains 1461 pieces in stock. Both are available as new original components.
