ELM 4-1.5MM Equivalent & Substitute Parts

Part Overview

The ELM 4-1.5MM is a T1 LED standoff holder manufactured by Bivar Inc., constructed from black PVC material with a 0.059" (1.50mm) length specification. This component is classified as Active product status and is RoHS3 compliant. LED holders serve as mechanical mounting and positioning devices for T1 LED packages in electronic assemblies. Identifying equivalent and substitute parts is necessary when the primary part number becomes unavailable, when inventory optimization is required, or when design modifications necessitate alternative mechanical specifications within compatible parameter ranges.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ELM 4-1.5MM is determined by the following parameters:

Primary substitution criteria:

• LED Type: T1 (non-negotiable mechanical compatibility)
• Material: PVC (maintains chemical and thermal properties)
• Color: Black (aesthetic and functional consistency)
• RoHS Status: RoHS3 Compliant (regulatory requirement)
• Moisture Sensitivity Level: 1 (Unlimited) (environmental tolerance equivalence)

Secondary consideration:

• Length specification: The standoff length (0.059" to 0.060") represents a tolerance range of 0.001" (0.02mm), which falls within acceptable mechanical variation for typical LED mounting applications. Parts within this dimensional range maintain mechanical compatibility with designed PCB clearances and LED package positioning.

The ELM 4-1.5MM can be substituted with ELM 4-060 and ELM 5-060, both of which maintain identical LED type, material, color, and compliance specifications while operating within the specified length tolerance band.

Parameter Comparison

Engineering Selection Recommendations

All three parts—ELM 4-1.5MM, ELM 4-060, and ELM 5-060—carry Active product status with full RoHS3 compliance and equivalent MSL ratings. The primary distinction lies in the series designation (ELM 4 versus ELM 5) and length specification within a 0.001" tolerance band.

Selection among these parts should be based on:

1. Series compatibility: ELM 4 series parts (ELM 4-1.5MM and ELM 4-060) maintain identical series designation and are direct equivalents. ELM 5-060 represents a cross-series substitute suitable when ELM 4 parts are unavailable.

2. Availability: Current inventory indicates ELM 4-060 (5080 pcs) and ELM 5-060 (3235 pcs) have substantially higher availability than the primary part specification.

3. Compliance assurance: All parts satisfy RoHS3 and MSL requirements, ensuring regulatory and environmental compatibility across designs utilizing any of these alternatives.

Frequently Asked Questions (FAQ)

Q: Are ELM 4-060 and ELM 5-060 directly interchangeable with ELM 4-1.5MM?

A: Yes, both parts are functionally equivalent substitutes. All three maintain identical LED type (T1), material (PVC), color (Black), and compliance specifications. The length variation (0.059" versus 0.060") represents a 0.001" tolerance margin standard in mechanical LED mounting applications.

Q: What is the practical difference between ELM 4-060 and ELM 5-060?

A: The primary difference is the series designation (ELM 4 versus ELM 5). Both parts meet all electrical and mechanical substitution criteria. Series designation typically reflects manufacturing process or product line grouping and does not affect T1 LED mounting functionality.

Q: Can I use these parts interchangeably on the same PCB assembly?

A: Yes. The 0.001" length difference falls within standard mechanical tolerances for T1 LED standoff mounting. PCB design clearances and LED package positioning accommodate this dimensional variation.

Q: What considerations apply to bulk purchasing of substitutes?

A: ELM 4-060 and ELM 5-060 demonstrate significantly higher inventory levels (5080 and 3235 pcs respectively) compared to ELM 4-1.5MM, potentially offering cost and delivery advantages. Confirm compatibility with design specifications and procurement requirements before transitioning to alternate part numbers.

Q: Are there regulatory or environmental differences between these parts?

A: No. All three parts carry identical RoHS3 compliance status and MSL rating (1, Unlimited), confirming equivalent environmental and regulatory performance across applications.
