ELM 4-920 LED Standoff Equivalent & Substitute Parts

Part Overview

The ELM 4-920 is a T1 LED standoff manufactured by Bivar Inc., designed for vertical mounting applications with a 0.920" (23.37mm) length. This component is constructed from black PVC material and accommodates 3MM LED packages with 2-lead configurations. 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 4-920 is determined by strict parameter alignment across the following critical dimensions:

Mechanical Compatibility Parameters:

• LED type classification (T1)
• LED package size (3MM)
• Lead configuration (2LD)
• Mounting orientation (Vertical)
• Material composition (Black PVC)
• Length tolerance (within 0.010" / 0.25mm variance)

Compliance & Environmental Parameters:

• RoHS3 compliance status
• Moisture Sensitivity Level (MSL 1)
• Packaging format (Bag)

Manufacturing Parameters:

• Manufacturer consistency (Bivar Inc.)
• Product status (Active)

The ELM 5-23MM qualifies as a parametric equivalent based on matching all mechanical, compliance, and environmental criteria. The length specification of 0.910" (23.11mm) falls within acceptable mechanical tolerance for vertical LED standoff applications, representing a 0.010" (0.26mm) variance from the primary part specification.

Parameter Comparison

Engineering Selection Recommendations

Both the ELM 4-920 and ELM 5-23MM are Active products manufactured by Bivar Inc. with identical RoHS3 compliance and MSL 1 ratings. Selection between these parts is based on availability and application-specific length requirements.

The ELM 4-920 provides the specified 0.920" (23.37mm) length for applications requiring this exact dimension. Current inventory of 912 pieces supports immediate procurement.

The ELM 5-23MM offers an alternative with 0.910" (23.11mm) length, representing a 0.010" (0.26mm) reduction. This substitute is appropriate for applications where this dimensional variance is acceptable within mechanical tolerance specifications. Inventory availability of 7087 pieces provides extended supply security.

Both parts maintain identical electrical, mechanical, and compliance characteristics across all other parameters. Selection should be based on specific application length requirements and inventory availability.

Frequently Asked Questions (FAQ)

Q: What determines if ELM 5-23MM can substitute for ELM 4-920?

A: Substitution is valid when the application tolerates the 0.010" (0.26mm) length difference. Both parts share identical LED type (T1), package size (3MM), lead configuration (2LD), material (Black PVC), mounting orientation (Vertical), and compliance ratings (ROHS3, MSL 1). The length variance is the only mechanical difference.

Q: Are there electrical differences between these parts?

A: No. Both parts are mechanical standoffs for LED mounting. Electrical characteristics are determined by the LED component inserted into the standoff, not by the standoff itself.

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

A: Yes. Both ELM 4-920 and ELM 5-23MM are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity level.

Q: What is the significance of the 0.010" length difference?

A: The 0.010" (0.26mm) difference represents a 0.11% variance from the primary part specification. Substitution is valid only if the application design accommodates this dimensional tolerance.

Q: Are the packaging formats identical?

A: Yes. Both parts are supplied in Bag packaging format.

Q: Can I use ELM 5-23MM in a design originally specified for ELM 4-920?

A: Substitution is valid only if the application mechanical design accepts the 0.910" length specification. Design documentation must be reviewed to confirm tolerance acceptance.

Q: What is the inventory status for each part?

A: ELM 4-920 has 912 pieces in stock. ELM 5-23MM has 7087 pieces in stock.
