ELM 1-400 Equivalent & Substitute Parts

Part Overview

The ELM 1-400 is a T1 3/4 LED standoff manufactured by Bivar Inc., featuring a black PVC construction with a 0.400" (10.16mm) length. This component is classified as an active product and maintains ROHS3 compliance with unlimited moisture sensitivity rating. Alternative part numbers become necessary when original inventory is unavailable or when specific mechanical dimensions must be accommodated within application constraints.

Substitute Part Grouping Explanation

Substitution for the ELM 1-400 is determined by the following critical parameters: LED type (T1 3/4), material composition (black PVC), color (black), series classification (ELM 1), RoHS compliance status (ROHS3), and moisture sensitivity level (MSL 1). These parameters define the functional and mechanical compatibility envelope for direct substitution.

The identified substitute parts—ELM 1-10MM and ELM 1-385—maintain identical LED type, material, color, series, and compliance specifications. The primary distinction among these parts is the length dimension, which varies within a narrow range: 0.390" (9.91mm) for ELM 1-10MM and 0.385" (9.78mm) for ELM 1-385, compared to the 0.400" (10.16mm) of the main part. These length variations fall within mechanical tolerance ranges typical for LED standoff applications.

Parameter Comparison

Engineering Selection Recommendations

The ELM 1-400, ELM 1-10MM, and ELM 1-385 are all classified as active products with ROHS3 compliance and MSL 1 ratings, establishing functional equivalence across all regulatory and environmental parameters. Selection among these parts should be based on application-specific mechanical requirements and component availability.

For applications where the exact 0.400" (10.16mm) length is specified, the ELM 1-400 remains the primary choice. When the primary part is unavailable, the ELM 1-10MM and ELM 1-385 represent valid alternatives, provided that the reduced length of 0.390" (9.91mm) and 0.385" (9.78mm) respectively accommodates the mechanical design envelope of the application.

Frequently Asked Questions (FAQ)

Q: Can ELM 1-10MM and ELM 1-385 be used as direct replacements for ELM 1-400?

A: Both parts share identical electrical and material specifications (T1 3/4 LED type, black PVC construction, ROHS3 compliance, MSL 1). The primary difference is mechanical length. Substitution is valid when the reduced length fits the application's mechanical constraints.

Q: What is the length difference between these parts?

A: ELM 1-400 measures 0.400" (10.16mm), ELM 1-10MM measures 0.390" (9.91mm), and ELM 1-385 measures 0.385" (9.78mm). The cumulative variation between longest and shortest is 0.015" (0.38mm).

Q: Are all three parts manufactured by the same company?

A: Yes. All three parts are manufactured by Bivar Inc. and belong to the ELM 1 series, ensuring design consistency and compatibility within the product family.

Q: Do compliance and safety ratings differ between these parts?

A: No. All three parts carry identical RoHS3 compliance status and MSL 1 (unlimited moisture sensitivity) ratings. Environmental and regulatory characteristics are equivalent.

Q: Which part should be selected when inventory status is a consideration?

A: The ELM 1-400 has the highest inventory level at 1075 pieces. The ELM 1-10MM has 947 pieces in stock, and the ELM 1-385 has 750 pieces available. Selection should prioritize the primary part number when adequate stock exists.
