ELM 5-310 LED Standoff Equivalent & Substitute Parts

Part Overview

The ELM 5-310 is a T1 LED standoff manufactured by Bivar Inc., featuring a black PVC construction with a 0.310" (7.87mm) length. This component is designed for vertical mounting applications requiring precise standoff height specifications. The part maintains Active product status and is RoHS3 compliant with MSL Level 1 rating, indicating unlimited moisture sensitivity tolerance.

Substitute parts become necessary when the primary part experiences inventory constraints, supply chain disruptions, or when design specifications allow for minor dimensional variations within acceptable tolerances. The ELM 5-310 has three qualified substitute options within the Bivar Inc. product family, all maintaining identical material composition, LED type, and compliance certifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ELM 5-310 is determined by strict adherence to the following parameters:

Critical Parameters (Must Match):

• LED Type: T1 (physical form factor compatibility)
• Material: Black PVC (chemical and thermal properties)
• Color: Black (visual consistency)
• RoHS Status: ROHS3 Compliant (regulatory requirement)
• MSL Rating: 1 (Unlimited) (environmental tolerance)

Allowable Variation Parameter:

• Length: 0.310" ± tolerance range (0.315" and 0.320" variants permitted within mechanical design flexibility)

All three substitute parts (ELM 2-315, ELM 2-320, ELM 4-315) satisfy the critical parameter requirements. Length variations of 0.005" to 0.010" from the primary specification fall within standard mechanical tolerances for LED standoff applications and do not compromise functional performance or mounting compatibility.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection Criteria:

All substitute parts maintain Active product status and full RoHS3 compliance, qualifying them as valid alternatives to the ELM 5-310. Selection between the main part and substitutes should be based on:

1. Dimensional Tolerance Acceptance: Design specifications must accommodate length variations of ±0.005" to ±0.010" from the nominal 0.310" specification. ELM 2-315 and ELM 4-315 introduce 0.005" additional height; ELM 2-320 introduces 0.010" additional height.

2. Inventory Availability: ELM 2-320 offers the highest stock level (26,182 pcs), followed by ELM 2-315 (7,562 pcs) and ELM 4-315 (4,972 pcs). The primary ELM 5-310 maintains 824 pcs in inventory.

3. Series Consistency: ELM 2-series parts (ELM 2-315, ELM 2-320) belong to the ELM 2 product line; ELM 4-315 belongs to the ELM 4 product line. Series selection may be driven by existing design documentation or procurement standardization.

4. Compliance Verification: All parts satisfy ROHS3 and MSL Level 1 requirements. No additional compliance testing is required for substitution.

Frequently Asked Questions (FAQ)

Q: Can ELM 2-320 be used as a direct replacement for ELM 5-310?

A: ELM 2-320 is a qualified substitute provided the design specification permits a 0.010" (0.25mm) increase in standoff height. All other parameters—LED type, material, color, and compliance certifications—are identical. Mechanical design review is required to confirm dimensional tolerance acceptance.

Q: What is the maximum allowable length variation between the main part and substitutes?

A: The substitute parts range from 0.315" to 0.320", representing a maximum variation of 0.010" from the primary ELM 5-310 specification of 0.310". This variation falls within standard mechanical tolerances for LED standoff applications.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. ELM 2-315, ELM 2-320, and ELM 4-315 all carry ROHS3 Compliant certification, matching the primary part's environmental compliance status.

Q: Does MSL rating differ between the main part and substitutes?

A: No. All parts, including the main ELM 5-310 and all three substitutes, maintain MSL Level 1 (Unlimited) rating, indicating identical moisture sensitivity tolerance.

Q: Which substitute offers the best inventory availability?

A: ELM 2-320 maintains the highest stock level at 26,182 pcs, providing maximum supply chain flexibility. ELM 2-315 and ELM 4-315 offer secondary availability at 7,562 pcs and 4,972 pcs respectively.

Q: Can substitutes from different series (ELM 2 vs. ELM 4) be used interchangeably?

A: Yes, provided dimensional and compliance requirements are satisfied. ELM 2-315 and ELM 4-315 both specify 0.315" length and are functionally equivalent. Series designation reflects product line organization but does not restrict substitution eligibility.

Q: What packaging format is used for all parts?

A: All parts—ELM 5-310, ELM 2-315, ELM 2-320, and ELM 4-315—are supplied in Bag packaging format, ensuring consistent handling and storage procedures.
