ELM 4-240 LED Standoff Equivalent & Substitute Parts

Part Overview

The ELM 4-240 is a T1 LED standoff manufactured by Bivar Inc., featuring a black PVC construction with a 0.240" (6.10mm) length. This component is classified as an active product and serves as a mechanical mounting solution for T1 LED assemblies in vertical orientation. Substitute parts may be required due to inventory constraints, design revisions, or application-specific dimensional requirements while maintaining functional compatibility within the T1 LED standoff category.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ELM 4-240 is determined by the following critical parameters:

Primary Compatibility Criteria:

• LED Type: T1 (all substitutes must accommodate T1 LED form factor)
• Color: Black (visual and material consistency)
• Material: PVC or equivalent polymer (mechanical and thermal properties)
• RoHS Compliance: ROHS3 Compliant (regulatory requirement)
• Moisture Sensitivity Level: 1 (Unlimited) (environmental tolerance)

Secondary Dimensional Tolerance:

• Length: 0.240" ± tolerance range (mechanical fit in PCB or assembly)

The substitute parts ELM 4-6MM, ELM 5-235, and H-131C-1-120 meet the primary criteria. Dimensional variations in length (0.235" to 0.250") fall within acceptable mechanical substitution ranges for T1 LED standoff applications. The H-131C-1-120 substitutes nylon material for PVC while maintaining all other critical parameters.

Parameter Comparison

Engineering Selection Recommendations

ELM 4-6MM: Direct parametric equivalent with identical length (0.240" / 6.10mm) and material composition (PVC). Recommended as primary substitute when ELM 4-240 inventory is unavailable. All compliance certifications and environmental ratings are equivalent.

ELM 5-235: Functionally compatible substitute with minimal length variance (0.235" vs. 0.240", -0.005" difference). Suitable for applications where dimensional tolerance permits. Higher inventory availability (20,398 pcs) supports supply chain continuity. Material and compliance specifications remain equivalent.

H-131C-1-120: Material alternative utilizing nylon instead of PVC with length of 0.250" (+0.010" variance). Acceptable for applications requiring enhanced mechanical properties or thermal resistance. All regulatory compliance and MSL ratings maintained. Select when PVC material constraints exist or when nylon properties provide design advantages.

All three substitute parts maintain active product status and ROHS3 compliance, ensuring regulatory and supply chain viability.

Frequently Asked Questions (FAQ)

Q: Can ELM 4-6MM be used as a direct replacement for ELM 4-240?

A: Yes. ELM 4-6MM is a parametric equivalent with identical length (0.240" / 6.10mm), material (PVC), color (black), and all compliance ratings. It functions as a direct substitute without design modification.

Q: What is the maximum acceptable length variation for T1 LED standoff substitution?

A: Based on the provided substitute parts, length variations of ±0.010" (0.235" to 0.250") are within acceptable mechanical substitution range for T1 LED standoff applications. Verify specific PCB or assembly design tolerances for your application.

Q: Is H-131C-1-120 suitable as a substitute despite nylon material instead of PVC?

A: Yes. H-131C-1-120 maintains all critical parameters: T1 LED compatibility, black color, 0.250" length, ROHS3 compliance, and MSL 1 rating. Nylon material provides equivalent mechanical performance for standard T1 LED mounting applications. Material selection depends on specific thermal or mechanical requirements of your design.

Q: Do all substitute parts have the same moisture sensitivity rating?

A: Yes. All substitute parts (ELM 4-6MM, ELM 5-235, H-131C-1-120) carry MSL 1 (Unlimited) rating, identical to the ELM 4-240. No additional moisture control measures are required during handling or storage.

Q: Are there packaging differences between the main part and substitutes?

A: All parts are supplied in bag packaging. Verify quantity requirements and lead times with your supplier, as inventory levels vary (ELM 4-240: 701 pcs; ELM 4-6MM: 1,737 pcs; ELM 5-235: 20,398 pcs; H-131C-1-120: 1,950 pcs).

Q: Which substitute offers the best supply chain availability?

A: ELM 5-235 provides the highest inventory level at 20,398 pcs, supporting extended supply continuity. Length variance of -0.005" is minimal and acceptable for most applications.
