ELM 4-870 LED Standoff Equivalent & Substitute Parts

Part Overview

The ELM 4-870 is a T1 LED standoff manufactured by Bivar Inc., designed for vertical mounting applications with a 0.870" (22.10mm) length. This component features a black PVC construction and accommodates 3MM LED configurations with 2-lead connections. The part maintains Active product status and is ROHS3 compliant with unlimited moisture sensitivity rating (MSL 1).

Substitute parts are identified when equivalent electrical and mechanical parameters align with the original specification, enabling direct replacement in applications where dimensional tolerance and performance characteristics remain within acceptable engineering limits.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ELM 4-870 is determined by the following critical parameters:

Mandatory Matching Parameters:

• Manufacturer: Bivar Inc.
• LED Type: T1
• Material: PVC
• Color: Black
• Lead Configuration: 2LD (3MM)
• Mounting Style: Vertical
• RoHS Compliance: ROHS3 Compliant
• Moisture Sensitivity Level: 1

Allowable Variation:

• Length tolerance within mechanical design constraints of the application

The ELM 5-23MM qualifies as a parametric equivalent based on identical electrical and mechanical specifications across all mandatory parameters. The length differential of 0.040" (1.01mm) between the ELM 4-870 (0.870") and ELM 5-23MM (0.910") represents a minor dimensional variation within standard engineering tolerances for standoff applications.

Parameter Comparison

Engineering Selection Recommendations

Both the ELM 4-870 and ELM 5-23MM maintain Active product status with full ROHS3 compliance and identical MSL ratings. Selection between these parts is determined by mechanical fit requirements within the target application.

The ELM 4-870 is specified for applications requiring a 0.870" standoff height. The ELM 5-23MM provides a 0.910" standoff height and serves as a substitute when the additional 0.040" clearance is compatible with circuit board layout and component spacing constraints.

Both parts are manufactured by Bivar Inc. using identical material composition, electrical configuration, and compliance certifications, ensuring functional equivalence within the specified dimensional parameters.

Frequently Asked Questions (FAQ)

Q: Can the ELM 5-23MM directly replace the ELM 4-870 in all applications?

A: The ELM 5-23MM functions as a parametric equivalent for the ELM 4-870 across all electrical and material specifications. Substitution is valid when the 0.040" (1.01mm) length increase does not conflict with mechanical constraints such as PCB clearance, enclosure height, or component spacing requirements.

Q: What are the critical parameters that must match for substitution?

A: Manufacturer (Bivar Inc.), LED type (T1), material (PVC), color (Black), lead configuration (2LD for 3MM), mounting style (Vertical), RoHS compliance (ROHS3), and moisture sensitivity level (MSL 1) must remain identical. Length variation is the only allowable parameter difference.

Q: Are both parts available in the same packaging format?

A: Both the ELM 4-870 and ELM 5-23MM are supplied in Bag packaging, ensuring consistent handling and storage requirements.

Q: Do both parts carry the same regulatory compliance certifications?

A: Yes. Both parts are ROHS3 compliant with ECCN classification EAR99 and HTSUS code 3926.90.9985, meeting identical regulatory requirements for export and use.

Q: What inventory levels are available for each part?

A: The ELM 4-870 has 973 pieces in stock. The ELM 5-23MM has 7087 pieces in stock, providing greater availability for high-volume applications.
