ELM 3-445 Equivalent & Substitute Parts

Part Overview

The ELM 3-445 is a T1 3/4 LED standoff manufactured by Bivar Inc., constructed from black PVC material with a length of 0.445" (11.30mm). This component functions as a vertical mounting standoff for LED applications requiring precise height specifications. The part maintains Active product status and is RoHS3 compliant with MSL 1 rating, indicating unlimited moisture sensitivity tolerance. Substitute parts are necessary when specific length requirements vary within acceptable tolerances, when inventory availability differs, or when alternative series options provide equivalent functional performance for the application.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ELM 3-445 is determined by the following critical parameters: LED type (T1 3/4), material composition (black PVC), mounting orientation (vertical), product status (Active), and compliance certifications (RoHS3, MSL 1). Length variations within the ELM series are permissible substitutes when the dimensional difference accommodates the application's mechanical tolerance stack. The ELM 3-445 substitutes with three qualified alternatives: ELM 3-450 (0.450" length), ELM 3-440 (0.440" length), and ELM 1-11MM (0.430" length). All substitute parts share identical LED type, material, color, and compliance ratings. Length differences range from -0.015" to +0.005" relative to the main part specification, representing acceptable mechanical variation for LED standoff applications.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts maintain Active product status and full RoHS3 compliance with MSL 1 rating, ensuring regulatory and environmental compatibility with the ELM 3-445. Selection between substitutes depends on mechanical length requirements specific to the application's PCB layout and LED positioning constraints.

ELM 3-450 provides the longest standoff height at 0.450" (11.43mm), representing a +0.005" increase from the main part. This option is suitable for applications requiring maximum vertical clearance.

ELM 3-440 offers a -0.005" reduction to 0.440" (11.18mm), providing minimal height reduction while maintaining ELM 3 series consistency. This part carries the highest inventory availability at 22,638 pieces.

ELM 1-11MM delivers the shortest option at 0.430" (10.92mm), representing a -0.015" reduction. This part transitions to the ELM 1 series while maintaining all functional and compliance parameters. Inventory availability is 1,475 pieces.

The ELM 3-445 main part carries 720 pieces in stock. Selection should prioritize application-specific length requirements as the primary criterion, with inventory availability as a secondary consideration.

Frequently Asked Questions (FAQ)

Q: What determines if a part can substitute for the ELM 3-445?

A: Substitute parts must maintain identical LED type (T1 3/4), material (black PVC), color (black), mounting orientation (vertical), and compliance certifications (RoHS3, MSL 1). Length variations are permissible within the mechanical tolerance range of the application.

Q: Are all substitute parts from the same manufacturer?

A: Yes. All substitute parts are manufactured by Bivar Inc., ensuring consistent quality and design standards.

Q: What is the maximum length variation between the ELM 3-445 and its substitutes?

A: Length variations range from -0.015" (ELM 1-11MM at 0.430") to +0.005" (ELM 3-450 at 0.450"), representing a total span of 0.020" across all qualified substitutes.

Q: Do all substitute parts have the same RoHS and MSL ratings?

A: Yes. All substitute parts are RoHS3 compliant with MSL 1 (Unlimited) rating, matching the ELM 3-445 specifications.

Q: Can I use ELM 1-11MM as a direct replacement for ELM 3-445?

A: ELM 1-11MM is a qualified substitute provided the application tolerates a -0.015" length reduction. The part maintains identical LED type, material, color, and compliance ratings. Series transition from ELM 3 to ELM 1 does not affect functional compatibility for LED standoff applications.

Q: What packaging format do all these parts use?

A: All parts are supplied in Bag packaging format.

Q: Which substitute has the best inventory availability?

A: ELM 3-440 carries the highest inventory at 22,638 pieces, compared to 8,972 pieces for ELM 3-450 and 1,475 pieces for ELM 1-11MM.
