ELM 3-400 Equivalent & Substitute Parts

Part Overview

The ELM 3-400 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 designed for vertical mounting applications requiring precise height specifications. The part maintains active product status and full ROHS3 compliance, ensuring continued availability and regulatory conformance. Identifying equivalent and substitute parts is necessary when the primary part is unavailable, when procurement lead times require alternative sourcing, or when application flexibility permits minor dimensional variations within specified tolerances.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ELM 3-400 are qualified based on the following parameters:

Critical Compatibility Parameters:

• LED Type: T1 3/4 (must match)
• Material: Black PVC (must match)
• Manufacturer: Bivar Inc. (same manufacturer preferred for design consistency)
• RoHS Status: ROHS3 Compliant (regulatory requirement maintained)
• MSL Rating: 1 (Unlimited) (moisture sensitivity alignment)

Allowable Variation:

• Length: Dimensional tolerance permits substitution of parts within ±0.015" (0.38mm) of the primary 0.400" specification

The identified substitute parts (ELM 1-10MM and ELM 1-385) satisfy these criteria through matching LED type, material composition, and compliance ratings. Length variations fall within acceptable mechanical tolerances for vertical mounting standoff applications.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain active product status with ROHS3 compliance and identical MSL ratings. Selection among ELM 3-400, ELM 1-10MM, and ELM 1-385 should be based on:

1. Primary Selection: ELM 3-400 remains the specified component for applications requiring the 0.400" length specification.

2. First Substitute: ELM 1-10MM provides the closest dimensional match at 0.390" (9.91mm), representing a 0.010" reduction from the primary specification. This part is suitable for applications where the standoff height reduction of 0.010" is within acceptable mechanical tolerances.

3. Secondary Substitute: ELM 1-385 offers the next dimensional option at 0.385" (9.78mm), representing a 0.015" reduction from the primary specification. This part is suitable for applications that permit the maximum allowable height variation.

All substitute parts are sourced from the same manufacturer and carry identical regulatory compliance certifications as the primary part.

Frequently Asked Questions (FAQ)

Q: Can ELM 1-10MM be used as a direct substitute for ELM 3-400? A: ELM 1-10MM shares identical LED type (T1 3/4), material (black PVC), and compliance ratings with ELM 3-400. The length difference of 0.010" (0.25mm) falls within standard mechanical tolerances for vertical standoff applications. Substitution is valid when the application design permits this dimensional variation.

Q: What is the maximum allowable length variation for substitution? A: The substitute parts listed (ELM 1-10MM and ELM 1-385) represent length variations of 0.010" and 0.015" respectively from the primary specification. These variations are within acceptable tolerances for LED standoff mounting applications where precise height is not a critical design constraint.

Q: Are there packaging differences between the primary part and substitutes? A: All parts (ELM 3-400, ELM 1-10MM, and ELM 1-385) are supplied in bag packaging, ensuring consistent handling and inventory management across part selections.

Q: Do the substitute parts maintain the same regulatory compliance as ELM 3-400? A: Yes. ELM 1-10MM and ELM 1-385 both carry ROHS3 compliance and MSL Level 1 (Unlimited) ratings, matching the compliance profile of ELM 3-400.

Q: What should guide the selection between ELM 1-10MM and ELM 1-385 when both are available? A: Both parts are functionally compatible substitutes. ELM 1-10MM provides a smaller dimensional variance (0.010") from the primary specification, while ELM 1-385 permits a larger variance (0.015"). Selection should be based on the specific mechanical clearances and height tolerances of the application design.
