ELM 2-280 LED Standoff Equivalent & Substitute Parts

Part Overview

The ELM 2-280 is a T1 LED standoff manufactured by Bivar Inc., featuring a black PVC construction with a 0.280" (7.11mm) length and 3MM 2-lead configuration. This component is classified as Active product status and is fully ROHS3 compliant. LED standoffs serve as mechanical mounting and alignment fixtures for through-hole LED assemblies in electronic equipment. Substitute parts may be required due to inventory availability, design specification updates, or manufacturing discontinuation of specific length variants.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ELM 2-280 is determined by the following critical parameters:

Primary Compatibility Criteria:

• LED Type: T1 (fixed requirement)
• Lead Configuration: 2LD (fixed requirement)
• Color: Black (fixed requirement)
• RoHS Compliance: ROHS3 Compliant (fixed requirement)
• Moisture Sensitivity Level: 1 (fixed requirement)

Variable Parameters Allowing Substitution:

• Length: 0.280" (7.11mm) primary specification; variants within the ELM 2 series with different lengths are parametrically equivalent
• Material: PVC (primary) or Nylon (alternative material with equivalent mechanical function)

The substitute parts ELM 2-285, H-101C, and H-101C-1 maintain all fixed parameters while varying in length and material composition. These variations remain functionally equivalent for LED standoff applications where the specific length tolerance and material type do not create design conflicts.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed maintain Active product status and full ROHS3 compliance, ensuring regulatory and supply chain continuity. Selection between ELM 2-280 and its substitutes should be based on the following engineering considerations:

ELM 2-280 (PVC, 0.280" length): Primary specification for applications requiring the exact 0.280" standoff height with PVC material properties.

ELM 2-285 (PVC, 0.285" length): Functionally equivalent PVC standoff with 0.005" additional length. Suitable for applications where the marginal length increase does not conflict with PCB layout or component clearance requirements.

H-101C and H-101C-1 (Nylon, 0.285" length): Functionally equivalent standoffs with nylon material substitution. Nylon offers alternative mechanical and thermal properties compared to PVC. Both H-101C and H-101C-1 are identical in specification and represent inventory variants of the same design.

All parts carry MSL 1 rating, indicating no moisture sensitivity restrictions during storage or handling.

Frequently Asked Questions (FAQ)

Q: Can ELM 2-280 be directly replaced with ELM 2-285?

A: ELM 2-285 is a parametric equivalent with identical specifications except for a 0.005" (0.13mm) length increase. Direct replacement is possible if the application design accommodates the additional standoff height without creating component interference or clearance violations.

Q: What is the material difference between ELM 2-280 and H-101C?

A: ELM 2-280 uses PVC material, while H-101C uses Nylon. Both materials are black and maintain identical LED type (T1), lead configuration (2LD), and compliance certifications. Material selection depends on application requirements for mechanical rigidity, thermal stability, and chemical resistance.

Q: Are H-101C and H-101C-1 interchangeable?

A: Yes. H-101C and H-101C-1 are identical in all electrical and mechanical parameters. The designation difference reflects inventory management or manufacturing batch tracking only.

Q: Do all substitute parts meet the same RoHS and MSL requirements?

A: Yes. All listed substitute parts are ROHS3 compliant and carry MSL 1 (Unlimited) rating, ensuring equivalent environmental and regulatory compliance.

Q: What determines whether a part can substitute for ELM 2-280?

A: Substitution requires matching the following fixed parameters: T1 LED type, 2-lead configuration, black color, ROHS3 compliance, and MSL 1 rating. Length and material may vary within the ELM 2 series and H-101 series while maintaining functional equivalence.
