ELM 4-155 LED Standoff Equivalent & Substitute Parts

Part Overview

The ELM 4-155 is a T1 LED standoff manufactured by Bivar Inc., designed for vertical mounting applications with a 0.155" (3.94mm) length specification. This component is constructed from black PVC material and accommodates 2-lead configurations. The part maintains Active product status and is ROHS3 compliant with MSL 1 rating, indicating unlimited moisture sensitivity protection.

Substitute parts are identified when equivalent electrical and mechanical parameters align with the main part specifications, allowing for direct functional replacement in applications where dimensional or series variations are acceptable within design tolerances.

Substitute Part Grouping Explanation

Substitution eligibility for the ELM 4-155 is determined by the following critical parameters:

Primary Substitution Criteria:

• LED Type: T1 (fixed requirement)
• Material: Black PVC (fixed requirement)
• Lead Configuration: 2LD (fixed requirement)
• Mounting Style: Vertical Surface Mount (fixed requirement)
• RoHS Compliance: ROHS3 Compliant (fixed requirement)
• MSL Rating: 1 (Unlimited) (fixed requirement)
• Manufacturer: Bivar Inc. (fixed requirement)

Variable Parameters Allowing Substitution:

• Length: 0.155" (3.94mm) primary specification; 0.150" (3.81mm) acceptable as parametric equivalent
• Series: ELM 4 primary series; ELM 5 acceptable as parametric equivalent

The identified substitutes (ELM 4-150 and ELM 5-150) maintain all fixed parameters while varying in length and series designation. These variations remain within the parametric equivalency scope for T1 LED standoff applications.

Parameter Comparison

Engineering Selection Recommendations

ELM 4-150 Selection Criteria: The ELM 4-150 maintains identical series designation (ELM 4) with the main part while reducing length by 0.005" (0.13mm). This substitute is appropriate for applications where the reduced standoff height accommodates design specifications. All compliance certifications, including ROHS3 and MSL 1 ratings, remain equivalent. Active product status ensures continued availability and supply chain stability.

ELM 5-150 Selection Criteria: The ELM 5-150 represents a series variant (ELM 5 versus ELM 4) with matching length reduction of 0.005" (0.13mm). This substitute applies to designs where series interchangeability is permitted. Compliance profile, including ROHS3 certification and MSL 1 rating, is identical to the main part. Active product status confirms ongoing manufacturability.

Compliance Considerations: All parts maintain ROHS3 compliance and EAR99 export classification. REACH status is unaffected for substitute parts. MSL 1 rating across all variants ensures unlimited moisture sensitivity protection without special handling requirements.

Frequently Asked Questions (FAQ)

Q: What is the primary difference between ELM 4-155 and ELM 4-150? A: The ELM 4-150 has a reduced length of 0.150" (3.81mm) compared to the ELM 4-155 at 0.155" (3.94mm). Both maintain identical series designation, material composition, and all electrical/mechanical specifications. The 0.005" (0.13mm) length reduction is the sole parametric variation.

Q: Can ELM 5-150 replace ELM 4-155 in all applications? A: ELM 5-150 is a parametric equivalent with series designation change from ELM 4 to ELM 5 and length reduction to 0.150" (3.81mm). Substitution is valid where design specifications permit series interchangeability and the reduced standoff height is acceptable.

Q: Are all substitute parts ROHS3 compliant? A: Yes. ELM 4-150 and ELM 5-150 are both ROHS3 compliant with identical certification status to the ELM 4-155.

Q: What is the MSL rating for substitute parts? A: All substitute parts carry MSL 1 (Unlimited) rating, identical to the main part. No special moisture sensitivity precautions are required during storage or handling.

Q: Do substitute parts have the same lead configuration? A: Yes. Both ELM 4-150 and ELM 5-150 maintain 2-lead (2LD) configuration matching the ELM 4-155.

Q: Are there packaging differences between the main part and substitutes? A: All parts are supplied in Bag packaging format. Inventory quantities vary: ELM 4-155 (750 Pcs), ELM 4-150 (12,323 Pcs), and ELM 5-150 (1,125 Pcs).

Q: What export classification applies to these parts? A: All parts are classified under ECCN EAR99 with HTSUS code 3926.90.9985, maintaining identical export compliance across the substitution group.
