ELM 4-425 Equivalent & Substitute Parts Reference

Part Overview

The ELM 4-425 is a T1 LED standoff manufactured by Bivar Inc., consisting of a black PVC vertical mount with a 0.425" (10.80mm) length and 3mm 2-lead configuration. This component is currently in active product status and ROHS3 compliant. Alternative models may be required when specific length specifications differ from the standard 0.425" dimension or when inventory availability necessitates substitution with compatible variants within the same product series.

Key Parameters

Substitute Part Grouping Explanation

The ELM 4-440 qualifies as a parametric equivalent to the ELM 4-425 based on the following matching parameters:

Matching Parameters:

• Manufacturer: Bivar Inc.
• Series: ELM 4
• Base Product Number: ELM4-4
• LED Configuration: T1, 3MM 2-Lead
• Color: Black
• Material: PVC
• Product Status: Active
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)
• Packaging: Bag

Variable Parameter:

• Length: 0.440" (11.18mm) versus 0.425" (10.80mm)

The ELM 4-440 differs only in the vertical mount length specification. When dimensional tolerance allows for the additional 0.015" (0.38mm) vertical height, the ELM 4-440 serves as a direct functional substitute while maintaining identical electrical and mechanical characteristics across all other parameters.

Parameter Comparison

Engineering Selection Recommendations

Both the ELM 4-425 and ELM 4-440 are active products from Bivar Inc. with identical ROHS3 compliance and MSL ratings. Selection between these parts is determined exclusively by mounting height requirements. The ELM 4-425 accommodates applications requiring a 0.425" (10.80mm) vertical standoff height. The ELM 4-440 accommodates applications requiring a 0.440" (11.18mm) vertical standoff height. Both parts maintain full compliance with applicable regulatory standards and certifications. Component selection should be based solely on dimensional fit within the target assembly.

Frequently Asked Questions (FAQ)

Q: Can ELM 4-440 be used as a direct replacement for ELM 4-425? A: The ELM 4-440 is compatible with ELM 4-425 applications only when the 0.015" (0.38mm) additional vertical height does not interfere with circuit board layout, component clearance, or enclosure constraints. Both parts share identical electrical and mechanical specifications for all other parameters.

Q: What is the critical difference between these parts? A: The only variable parameter is the vertical mount length. ELM 4-425 provides 0.425" (10.80mm) height, while ELM 4-440 provides 0.440" (11.18mm) height. All other specifications, including LED configuration, material, color, and compliance certifications, are identical.

Q: Are there supply or availability advantages to selecting ELM 4-440 over ELM 4-425? A: Both parts are active products with current inventory availability. Supply chain considerations should be evaluated independently based on project timeline and procurement requirements.

Q: Do both parts meet RoHS and regulatory requirements? A: Both ELM 4-425 and ELM 4-440 are ROHS3 compliant and carry identical regulatory classifications. Moisture sensitivity levels are equivalent at MSL 1 (Unlimited), indicating no special handling requirements during storage, transport, or assembly.

Q: What packaging format is used for these components? A: Both parts are supplied in bag packaging, suitable for automated placement or manual assembly workflows.
