ELM 4-940 LED Standoff Equivalent & Substitute Parts

Part Overview

The ELM 4-940 is a T1 LED standoff manufactured by Bivar Inc., designed for vertical mounting applications with a 0.940" (23.90mm) length. This component is constructed from black PVC material and accommodates 3MM LED configurations with 2-lead connections. The part maintains Active product status and is ROHS3 compliant, making it suitable for current production environments. Substitute parts are identified when inventory constraints, lead time requirements, or design flexibility necessitate alternative components that maintain functional and mechanical compatibility within specified parameter tolerances.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ELM 4-940 is determined by the following critical parameters:

Primary Compatibility Criteria:

• LED Type: T1 (fixed requirement)
• Material: Black PVC (fixed requirement)
• LED Configuration: 3MM 2LD (fixed requirement)
• Manufacturer: Bivar Inc. (fixed requirement)
• RoHS Status: ROHS3 Compliant (fixed requirement)
• Moisture Sensitivity Level: 1 (Unlimited) (fixed requirement)

Allowable Variation:

• Length tolerance: Mechanical length variation within 0.030" (0.76mm) is permissible for vertical standoff applications where mounting height flexibility exists within the design envelope.

The substitute part ELM 5-23MM meets all primary compatibility criteria and falls within the allowable length tolerance range (0.910" vs. 0.940", representing a 0.030" difference).

Parameter Comparison

Engineering Selection Recommendations

Both the ELM 4-940 and ELM 5-23MM are Active products manufactured by Bivar Inc. with identical ROHS3 compliance and Moisture Sensitivity Level ratings. Selection between these parts is based on the following engineering factors:

ELM 4-940 Selection Criteria:

• Primary design specification calls for 0.940" (23.90mm) standoff height
• Inventory availability: 678 Pcs New Original In Stock

ELM 5-23MM Selection Criteria:

• Design allows for 0.910" (23.11mm) standoff height with 0.030" mechanical tolerance
• Higher inventory availability: 7087 Pcs New Original In Stock
• Reduced lead time risk due to larger stock position

Both parts satisfy identical electrical, mechanical, and compliance requirements. The 0.030" length difference does not affect functional performance in applications where vertical mounting height tolerance is engineered into the design.

Frequently Asked Questions (FAQ)

Q: Can ELM 5-23MM be used as a direct replacement for ELM 4-940?

A: Yes, within design specifications that accommodate the 0.030" (0.76mm) length difference. Both parts are T1 LED standoffs with identical material composition, LED configuration, and compliance ratings. Verify that your PCB layout and mechanical assembly design allow for the shorter standoff height of 0.910" (23.11mm).

Q: What is the maximum allowable length variation between these parts?

A: The ELM 5-23MM is 0.030" shorter than the ELM 4-940. This variation is acceptable for vertical standoff applications where the design envelope permits mechanical height flexibility. Confirm that component clearance and mounting requirements are satisfied with the reduced height.

Q: Are the packaging specifications identical?

A: Yes. Both parts are supplied in Bag packaging, maintaining consistent handling and storage requirements.

Q: Do both parts meet the same compliance standards?

A: Yes. Both ELM 4-940 and ELM 5-23MM are ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited), meeting identical environmental and regulatory requirements.

Q: Which part should be selected for new designs?

A: Selection depends on mechanical design constraints. If the design accommodates 0.910" (23.11mm) standoff height, ELM 5-23MM offers superior inventory availability and reduced procurement risk. If the design specifically requires 0.940" (23.90mm) height, use ELM 4-940.
