ELM 4-935 LED Standoff Equivalent & Substitute Parts

Part Overview

The ELM 4-935 is a T1 LED standoff manufactured by Bivar Inc., designed for vertical mounting applications requiring a 0.935" (23.75mm) height. 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 4-935 is determined by strict parameter matching across the following critical dimensions:

Mandatory Matching Parameters:

• LED Type: T1 (physical package compatibility)
• Material: Black PVC (mechanical and environmental properties)
• LED Configuration: 3MM 2LD (electrical and mechanical interface)
• Orientation: Vertical mounting (SR VERT)
• RoHS Status: ROHS3 Compliant (regulatory requirement)
• Moisture Sensitivity Level: 1 (Unlimited) (storage compatibility)

Allowable Variance:

• Length: Within 0.025" (0.635mm) tolerance of 0.935" (23.75mm) nominal dimension

The ELM 5-23MM meets all mandatory matching parameters and falls within the allowable length variance, qualifying as a parametric equivalent substitute.

Engineering Selection Recommendations

Primary Selection: ELM 4-935 Use the ELM 4-935 when the exact 0.935" (23.75mm) height is required by circuit board layout specifications or mechanical assembly constraints. This part is Active status with full inventory availability (685 Pcs).

Substitute Selection: ELM 5-23MM The ELM 5-23MM is a valid parametric equivalent when the 0.025" (0.635mm) length variance is acceptable within the application's mechanical tolerance stack. This substitute offers significantly higher inventory availability (7087 Pcs) and may provide supply chain advantages. Both parts maintain identical RoHS3 compliance, MSL rating, and electrical interface specifications.

Compliance Basis: Both parts are ROHS3 compliant with MSL 1 (Unlimited) rating, ensuring compatibility with standard storage, handling, and assembly processes. Selection between these parts should be based solely on mechanical height requirements and inventory availability.

Frequently Asked Questions (FAQ)

Q: Can ELM 5-23MM be used as a direct replacement for ELM 4-935? A: The ELM 5-23MM is a parametric equivalent with a 0.025" (0.635mm) shorter length (0.910" vs. 0.935"). It is a valid substitute when this height difference is within the application's mechanical tolerance. Both parts share identical LED type, material, configuration, orientation, and compliance ratings.

Q: What is the significance of the length difference between these parts? A: The ELM 4-935 provides 0.935" (23.75mm) mounting height, while the ELM 5-23MM provides 0.910" (23.11mm). The 0.025" variance must be evaluated against circuit board layout, component clearance requirements, and mechanical assembly specifications. If exact height is critical, use ELM 4-935.

Q: Are both parts RoHS3 compliant? A: Yes. Both ELM 4-935 and ELM 5-23MM are ROHS3 compliant with identical Moisture Sensitivity Level 1 (Unlimited) ratings, ensuring compatibility with standard manufacturing and storage environments.

Q: What packaging format is used for both parts? A: Both parts are supplied in Bag packaging format, suitable for standard component handling and assembly processes.

Q: Do these parts have different lead times or availability? A: Inventory levels differ: ELM 4-935 has 685 Pcs in stock, while ELM 5-23MM has 7087 Pcs in stock. Both maintain Active product status with Bivar Inc.

Q: Can I use ELM 5-23MM if my design specifies ELM 4-935? A: Substitution is permissible only when the 0.025" height difference does not violate mechanical design constraints, clearance requirements, or assembly specifications. Engineering review of the specific application is required to confirm compatibility.
