ELM 4-405 LED Standoff Equivalent & Substitute Parts

Part Overview

The ELM 4-405 is a T1 LED standoff manufactured by Bivar Inc., designed for vertical mounting applications with a 0.405" (10.29mm) 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 equivalence within the allowed parameter specifications for this product category.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ELM 4-405 is determined by strict adherence to the following parameters:

Critical Matching Parameters:

• LED Type: T1 (physical package size)
• Material: PVC (mechanical and thermal properties)
• Color: Black (visual consistency)
• Lead Configuration: 2LD (electrical interface)
• Mounting Orientation: Vertical (PCB assembly compatibility)
• RoHS Status: ROHS3 Compliant (regulatory requirement)
• MSL Rating: 1 or equivalent (moisture handling)

Allowable Variance:

• Length: Tolerance within mechanical design constraints of the application

The ELM 5-390 qualifies as a parametric equivalent because it maintains all critical matching parameters while presenting a length variation of 0.015" (0.38mm). Both components are manufactured by Bivar Inc., share identical material composition, color specification, lead configuration, and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

ELM 4-405 Selection Criteria:

• Primary choice when 0.405" (10.29mm) mounting height is specified in design documentation
• Recommended for applications with strict vertical clearance requirements
• Suitable for production environments with established supply chain for this part number

ELM 5-390 Selection Criteria:

• Acceptable substitute when design allows 0.015" (0.38mm) reduction in standoff height
• Applicable when ELM 4-405 inventory is unavailable or lead times exceed project requirements
• Maintains full compliance with ROHS3 and MSL specifications
• Both parts share identical electrical and mechanical interfaces for T1 LED packages

Both components are Active products manufactured by Bivar Inc. with ROHS3 compliance and unlimited moisture sensitivity rating. Selection between these parts depends solely on the mechanical height tolerance of the target application.

Frequently Asked Questions (FAQ)

Q: Can ELM 5-390 be used as a direct replacement for ELM 4-405?

A: ELM 5-390 is a parametric equivalent substitute provided the application design permits a 0.015" (0.38mm) reduction in standoff height. All electrical, material, and compliance specifications are identical. Verification of mechanical clearance in the PCB assembly is required.

Q: What is the primary difference between these two parts?

A: The only variance is the standoff length. ELM 4-405 provides 0.405" (10.29mm) height, while ELM 5-390 provides 0.390" (9.91mm) height. All other parameters—LED type, material, color, lead configuration, and compliance ratings—are identical.

Q: Are both parts ROHS3 compliant?

A: Yes. Both ELM 4-405 and ELM 5-390 are ROHS3 compliant with MSL rating of 1 (Unlimited moisture sensitivity level).

Q: What does the "2LD" designation mean?

A: 2LD indicates a 2-lead configuration, standard for T1 LED packages. Both parts support this lead arrangement for vertical PCB mounting.

Q: Can these parts be used interchangeably in all applications?

A: Interchangeability depends on the mechanical design tolerance of the specific application. The 0.015" height difference must be evaluated against PCB layout, component clearance, and assembly requirements. Electrical and material specifications are fully interchangeable.

Q: What is the packaging format for both parts?

A: Both ELM 4-405 and ELM 5-390 are supplied in Bag packaging format.
