ELM 5-435 Equivalent & Substitute Parts

Part Overview

The ELM 5-435 is a T1 LED standoff in black PVC with a length of 0.435" (11.05mm) and 2-lead configuration, manufactured by Bivar Inc. This component is Active in product status and ROHS3 compliant. LED standoffs function as mechanical supports and alignment devices for LED components in electronic assemblies. Locating equivalent and substitute parts becomes necessary due to inventory constraints, supply chain considerations, or design optimization requirements.

Key Parameters

Substitute Part Grouping Explanation

The ELM 4-440 qualifies as a parametric equivalent to the ELM 5-435 based on the following critical substitution parameters:

• LED Type: Both parts use T1 LED configuration
• Material: Both utilize black PVC construction
• Lead Configuration: Both feature 2-lead design
• Manufacturer: Both are manufactured by Bivar Inc.
• RoHS Compliance: Both meet ROHS3 standards
• MSL Rating: Both are rated MSL 1 (Unlimited)

The primary dimensional difference is the length specification: ELM 5-435 measures 0.435" (11.05mm) while ELM 4-440 measures 0.440" (11.18mm), a variance of 0.005" (0.13mm). This minor dimensional tolerance difference is within acceptable mechanical substitution parameters for LED standoff applications where precise vertical alignment or PCB height constraints are not critical design factors.

Parameter Comparison

Engineering Selection Recommendations

Both the ELM 5-435 and ELM 4-440 maintain Active product status, ensuring continued manufacturer support and availability. Both parts satisfy ROHS3 compliance requirements and carry identical MSL ratings. The ELM 4-440 is functionally equivalent for applications where the 0.005" dimensional variance does not impose critical height or alignment constraints. Selection between these parts should be based on specific PCB layout requirements, available inventory, and design documentation specifications.

Frequently Asked Questions (FAQ)

Q: Can the ELM 4-440 directly replace the ELM 5-435 in all applications?

A: The ELM 4-440 is a parametric equivalent with a length difference of 0.005" (0.13mm). Direct substitution is appropriate for applications without strict height tolerance requirements. Designs with critical vertical spacing constraints should evaluate the dimensional variance against specific mechanical clearances.

Q: Are there any compliance differences between these parts?

A: Both parts are ROHS3 compliant and carry identical MSL ratings of 1 (Unlimited). Regulatory compliance is equivalent, allowing substitution from an environmental and reliability standpoint.

Q: Why would the ELM 4-440 be preferred over the ELM 5-435?

A: Preferred selection depends on inventory availability, lead time, and design requirements. Both parts maintain Active product status from Bivar Inc., ensuring equal long-term reliability from a manufacturing perspective.

Q: Do these parts share the same packaging format?

A: Both parts are supplied in Bag packaging, maintaining consistent handling and logistics procedures.

Q: What dimensions must be verified before substitution?

A: The critical dimension requiring verification is the standoff length. The ELM 5-435 specifies 0.435" (11.05mm) while the ELM 4-440 specifies 0.440" (11.18mm). Confirmation that the 0.005" difference accommodates PCB design constraints is necessary before substitution.
