ELM 4-955 LED Standoff Equivalent & Substitute Parts

Part Overview

The ELM 4-955 is a T1 LED standoff manufactured by Bivar Inc., designed to mount 3MM LEDs in vertical orientation. This component is constructed from black PVC material with a length of 0.955" (24.26mm). The part maintains Active product status and carries ROHS3 compliance certification. Substitute parts are identified when equivalent electrical and mechanical parameters are maintained across the product series, ensuring functional interchangeability in applications where dimensional tolerance permits.

Substitute Part Grouping Explanation

Substitution for the ELM 4-955 is determined by equivalence in the following critical parameters: manufacturer (Bivar Inc.), LED type (T1), material composition (black PVC), mounting orientation (vertical), LED cavity size (3MM), RoHS compliance status, and MSL rating. The ELM 5-23MM qualifies as a parametric equivalent based on matching all these criteria. Length variation between the main part (0.955"/24.26mm) and the substitute (0.910"/23.11mm) represents a 0.045" (1.15mm) reduction. This dimensional difference is within tolerance for applications where LED standoff height does not drive form-factor requirements. Both parts share identical material, color, compliance certifications, and electrical characteristics for LED accommodation.

Parameter Comparison

Engineering Selection Recommendations

Both ELM 4-955 and ELM 5-23MM maintain Active product status with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Selection between these parts depends on the application's height tolerance. The ELM 4-955 provides the specified 0.955" dimension, while ELM 5-23MM offers a 0.910" alternative. For designs with strict vertical height constraints, the original part number should be maintained. For applications accommodating the reduced 0.045" height difference, ELM 5-23MM provides equivalent functionality with higher inventory availability (7087 units versus 1141 units).

Frequently Asked Questions (FAQ)

Q: Can ELM 5-23MM be used as a direct replacement for ELM 4-955? A: ELM 5-23MM qualifies as a parametric equivalent when application height tolerance permits a 0.045" (1.15mm) reduction in standoff length. Both parts accommodate T1 LEDs in 3MM cavities with identical material composition and compliance certifications.

Q: What are the critical parameters determining substitutability? A: Substitution eligibility is based on matching LED type (T1), cavity size (3MM), material (black PVC), mounting orientation (vertical), manufacturer (Bivar Inc.), and compliance status (ROHS3, MSL 1). Length variation is acceptable within the application's design tolerance.

Q: Are there compliance differences between the main part and substitute? A: No. Both ELM 4-955 and ELM 5-23MM maintain identical ROHS3 compliance status, MSL rating, ECCN classification (EAR99), and HTSUS code (3926.90.9985).

Q: What inventory considerations apply to part selection? A: ELM 5-23MM maintains higher inventory availability at 7087 pieces compared to 1141 pieces for ELM 4-955. Lead time and availability may influence part selection when height tolerance permits substitution.

Q: Do these parts share the same base product platform? A: ELM 4-955 and ELM 5-23MM belong to different product series (ELM 4 and ELM 5 respectively) with different base product numbers (ELM4-9 and ELM5-2). Functional equivalence exists within the specified parameter constraints, though they represent distinct SKUs in the manufacturer's product line.
