ELM 5-140 Equivalent & Substitute Parts

Part Overview

The ELM 5-140 is a T1 LED standoff manufactured by Bivar Inc., designed for vertical mounting applications requiring a 0.140" (3.56mm) height profile. This component features black PVC construction and is classified as active product status with ROHS3 compliance. Alternative models become necessary when inventory constraints occur or when specific height requirements of connected assemblies demand slight dimensional variations within the T1 LED standoff category.

Key Parameters

Substitute Part Grouping Explanation

The ELM 4-145 qualifies as a parametric equivalent to the ELM 5-140 based on the following allowable substitution criteria:

Common Parameters:

• LED Type: T1 (identical form factor)
• Material: PVC (identical construction material)
• Color: Black (identical visual specification)
• Manufacturer: Bivar Inc. (same manufacturer platform)
• RoHS Compliance: ROHS3 Compliant (identical regulatory status)
• Moisture Sensitivity Level: 1 (Unlimited) (identical handling requirements)

Allowable Variation:

• Height: 0.145" (3.68mm) versus 0.140" (3.56mm) — a 0.005" (0.12mm) dimensional difference

This height variation falls within acceptable parameters for T1 LED standoff applications where minor vertical spacing adjustments do not compromise electrical or mechanical assembly integrity.

Parameter Comparison

Engineering Selection Recommendations

Both the ELM 5-140 and ELM 4-145 share identical active product status and ROHS3 compliance certifications, making them functionally equivalent from regulatory and lifecycle perspectives. The ELM 4-145 maintains the same moisture sensitivity rating (MSL 1 – Unlimited), indicating equivalent storage and handling requirements. Selection between these parts depends solely on dimensional tolerance requirements for specific PCB or assembly layouts. The 0.005" height difference should be evaluated against mechanical stack-up constraints in the target application.

Frequently Asked Questions (FAQ)

Q: Can the ELM 4-145 directly replace the ELM 5-140 in my assembly?

A: Yes, from an electrical and material perspective. Both parts are T1 LED standoffs manufactured from black PVC by Bivar Inc. with identical RoHS and MSL ratings. Mechanical fit depends on your application's tolerance for the 0.005" (0.12mm) height difference.

Q: What is the primary difference between these two parts?

A: The ELM 4-145 is 0.005" taller (0.145" vs. 0.140"). Both parts share identical LED type, material, color, and regulatory compliance specifications.

Q: Are there packaging differences between these parts?

A: Both parts are supplied in bag packaging. No alternative packaging configurations are specified in the current data.

Q: Do these parts have identical moisture sensitivity requirements?

A: Yes. Both the ELM 5-140 and ELM 4-145 carry MSL rating of 1 (Unlimited), requiring no special moisture control during storage or handling.

Q: Which part should I select if my PCB has strict height constraints?

A: The ELM 5-140 provides the smaller profile at 0.140" height. Select the ELM 4-145 only if the additional 0.005" clearance is acceptable within your assembly design.
