ELM 4-525 Equivalent & Substitute Parts

Part Overview

The ELM 4-525 is a T1 LED Standoff manufactured by Bivar Inc., constructed from black PVC material with a height of 0.525" (13.34mm). This component is actively produced and RoHS3 compliant, with unlimited moisture sensitivity rating (MSL 1). Alternative models become necessary when specific height requirements differ due to PCB layout constraints, clearance limitations, or design modifications that require standoff lengths outside the 0.525" specification.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the ELM 4-525 is determined by three critical parameters: LED type (T1), material composition (black PVC), and physical length tolerance. The ELM 2-500 and ELM 2-510 qualify as parametric equivalents because they maintain identical LED specifications (T1) and material properties (black PVC), with length variations of ±0.015" (±0.38mm) from the primary part. These minor height differences remain within functional tolerances for most LED mounting applications where vertical clearance allows for this variation range. Both substitute parts share the same RoHS3 compliance and MSL rating as the primary part, ensuring compatibility in restricted substance environments.

Parameter Comparison

Engineering Selection Recommendations

All three parts (ELM 4-525, ELM 2-500, and ELM 2-510) maintain active production status with ROHS3 compliance and identical moisture sensitivity ratings. Selection between these parts depends solely on the height requirement of the specific application:

• ELM 4-525: Select when 0.525" (13.34mm) standoff height is required.
• ELM 2-510: Select when 0.510" (12.95mm) standoff height is required; offers closest dimensional match to ELM 4-525.
• ELM 2-500: Select when 0.500" (12.70mm) standoff height is required.

All parts are manufactured by Bivar Inc. and carry identical regulatory compliance certifications, ensuring interchangeability within the defined length parameters.

Frequently Asked Questions (FAQ)

Q: What determines if ELM 2-500 or ELM 2-510 can substitute for ELM 4-525?

A: Substitution is possible when the application's vertical clearance accommodates the reduced height of the substitute part. ELM 2-510 has a 0.015" (0.38mm) height reduction compared to ELM 4-525, while ELM 2-500 has a 0.025" (0.63mm) reduction. Both parts maintain identical LED type (T1), material (black PVC), and compliance specifications.

Q: Are there electrical differences between the three parts?

A: No electrical differences exist. All three parts are passive mechanical standoffs for T1 LEDs with identical functional characteristics.

Q: Do these parts share the same packaging?

A: Yes, all three parts are supplied in bag packaging.

Q: Can I mix these parts in the same assembly?

A: Part selection depends on mechanical requirements. If the application requires uniform standoff height across multiple LED positions, use a single part number. If height variation can be accommodated by the design, any of the three parts may be used.

Q: Are there supply or cost considerations between these substitutes?

A: The provided data indicates inventory availability (ELM 4-525: 1135 pcs, ELM 2-500: 4519 pcs, ELM 2-510: 1846 pcs), showing all parts are in active stock. Part selection should be based on mechanical compatibility rather than availability.
