ELM 4-420 LED Standoff Equivalent & Substitute Parts

Part Overview

The ELM 4-420 is a T1 LED standoff manufactured by Bivar Inc., designed for vertical mounting applications with a 0.420" (10.67mm) height. 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 may be required due to inventory constraints, application-specific height requirements, or supply chain considerations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ELM 4-420 is determined by the following critical parameters:

Fixed Parameters (Non-Substitutable):

• Manufacturer: Bivar Inc.
• Series: ELM 4
• LED Type: T1
• Color: Black
• Material: PVC
• Lead Configuration: 2LD
• RoHS Compliance: ROHS3
• MSL Rating: 1

Variable Parameter (Allows Substitution):

• Height: The ELM 4-420 operates at 0.420" (10.67mm). Substitute parts within the ELM 4 series may vary in height specification while maintaining all other electrical and mechanical characteristics.

The ELM 4-440 qualifies as a parametric equivalent because it maintains identical specifications across all fixed parameters while offering an alternative height dimension of 0.440" (11.18mm).

Parameter Comparison

Engineering Selection Recommendations

Both the ELM 4-420 and ELM 4-440 maintain Active product status with full ROHS3 compliance and unlimited moisture sensitivity ratings. Selection between these parts is determined by application-specific height requirements:

• ELM 4-420 is specified for applications requiring a 0.420" (10.67mm) standoff height.
• ELM 4-440 is specified for applications requiring a 0.440" (11.18mm) standoff height.

Both parts are manufactured by Bivar Inc. within the same ELM 4 series and share identical electrical and mechanical characteristics except for height dimension. Component selection must align with PCB layout specifications and mechanical clearance requirements of the target application.

Frequently Asked Questions (FAQ)

Q: Can ELM 4-440 be used as a direct replacement for ELM 4-420?

A: ELM 4-440 is a parametric equivalent with identical specifications except for height. Substitution is valid only if the application PCB layout and mechanical design accommodate the 0.020" (0.51mm) height difference.

Q: What parameters must remain constant for substitution eligibility?

A: Manufacturer (Bivar Inc.), Series (ELM 4), LED Type (T1), Color (Black), Material (PVC), Lead Configuration (2LD), RoHS compliance level, and MSL rating must all remain unchanged. Only height dimension varies between qualified substitutes.

Q: Are both parts ROHS3 compliant?

A: Yes. Both ELM 4-420 and ELM 4-440 are ROHS3 compliant with MSL Rating 1 (Unlimited), meeting current environmental and regulatory requirements.

Q: What is the packaging format for these parts?

A: Both parts are supplied in Bag packaging format.

Q: How does the height difference affect component selection?

A: The 0.020" (0.51mm) height differential between ELM 4-420 and ELM 4-440 must be evaluated against PCB layout constraints, LED lens clearance requirements, and mechanical assembly specifications. Height selection is application-dependent and must be verified against design documentation.
