ELM 5-250 LED Standoff Equivalent & Substitute Parts

Part Overview

The ELM 5-250 is a T1 LED standoff manufactured by Bivar Inc., designed for vertical mounting applications. This component features a black PVC construction with a 0.250" (6.35mm) length specification. The part maintains Active product status and is RoHS3 compliant, making it suitable for current electronic assembly requirements.

Substitute parts become necessary when the primary component experiences supply constraints, extended lead times, or inventory depletion. Alternative equivalent parts provide functional compatibility while maintaining critical electrical and mechanical specifications required for proper LED mounting and alignment in circuit board assemblies.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ELM 5-250 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)
• Mounting Orientation: Vertical (SR VERT designation)
• RoHS Compliance: ROHS3 Compliant (regulatory requirement)
• Moisture Sensitivity Level: 1 (Unlimited)

Secondary Consideration:

• Length tolerance: Substitutes within 0.010" (0.25mm) variation of 0.250" (6.35mm) specification maintain functional compatibility for standard PCB mounting applications

Material variation between PVC and Nylon is permitted when all other parameters align, as both materials provide equivalent mechanical support and electrical isolation properties for T1 LED standoff applications.

Engineering Selection Recommendations

ELM 4-6MM Selection Criteria: The ELM 4-6MM provides direct substitution for the ELM 5-250 with identical material composition (PVC) and LED type (T1). The length differential of 0.010" (0.25mm) falls within acceptable tolerance for standard vertical LED mounting applications. This substitute maintains equivalent RoHS3 compliance and MSL rating. Higher inventory availability (1737 pcs) supports supply chain continuity.

H-131C-1-120 Selection Criteria: The H-131C-1-120 offers substitution with matching length specification (0.250") and LED type (T1), with material variation from PVC to Nylon. Both materials provide equivalent mechanical support and electrical isolation for T1 standoff applications. This substitute maintains full RoHS3 compliance and MSL rating. Highest inventory availability (1950 pcs) ensures supply reliability. Material change from PVC to Nylon does not affect functional performance in standard mounting configurations.

Both substitutes maintain Active product status and full regulatory compliance, supporting long-term design stability.

Frequently Asked Questions (FAQ)

Q: Can ELM 4-6MM replace ELM 5-250 in all applications?

A: Yes. The ELM 4-6MM provides functional equivalence for T1 LED vertical mounting. The 0.010" length difference is within standard PCB assembly tolerances. Both parts share identical material (PVC), color (Black), LED type (T1), and regulatory compliance (ROHS3).

Q: What is the difference between PVC and Nylon material options?

A: Both PVC (ELM 5-250, ELM 4-6MM) and Nylon (H-131C-1-120) provide equivalent mechanical support and electrical isolation for T1 LED standoff applications. Material selection does not affect electrical performance or mounting compatibility. Nylon offers slightly enhanced durability in high-temperature environments, though both materials operate identically under standard assembly conditions.

Q: Does the 0.010" length difference between ELM 5-250 and ELM 4-6MM affect PCB assembly?

A: No. The 0.010" (0.25mm) length variation is within standard PCB mounting tolerances for vertical LED standoff applications. Both parts accommodate T1 LED form factors identically and maintain equivalent vertical alignment on circuit boards.

Q: Are all three parts RoHS3 compliant?

A: Yes. ELM 5-250, ELM 4-6MM, and H-131C-1-120 are all ROHS3 compliant with MSL rating of 1 (Unlimited), meeting current regulatory requirements for electronic component manufacturing.

Q: Which substitute offers the best inventory availability?

A: H-131C-1-120 provides the highest inventory level at 1950 pcs, followed by ELM 4-6MM at 1737 pcs. Both substitutes exceed the main part inventory (794 pcs), supporting supply chain flexibility.

Q: Can I mix ELM 5-250 and H-131C-1-120 in the same assembly?

A: Yes. Both parts share identical length (0.250"), LED type (T1), color (Black), and regulatory compliance. Material variation (PVC vs. Nylon) does not affect functional compatibility or assembly performance.
