ELM 4-895 LED Standoff Equivalent & Substitute Parts

Part Overview

The ELM 4-895 is a T1 LED standoff manufactured by Bivar Inc., designed for vertical mounting applications with a 0.895" (22.73mm) 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 4-895 is determined by the following critical parameters:

Primary Compatibility Criteria:

• LED Type: T1 (fixed requirement)
• Material: Black PVC (fixed requirement)
• Lead Configuration: 2LD (fixed requirement)
• Mounting Orientation: Vertical (fixed requirement)
• Color: Black (fixed requirement)
• Manufacturer: Bivar Inc. (same manufacturer ecosystem)

Allowable Variation:

• Height: Within mechanical tolerance range (0.895" nominal ±0.015")

The substitute part ELM 5-23MM shares identical LED type, material composition, lead configuration, mounting orientation, and color specification. The height differential of 0.015" (0.38mm) falls within standard mechanical tolerance for LED standoff applications where vertical spacing accommodates minor dimensional variation.

Engineering Selection Recommendations

ELM 4-895 Selection Criteria:

• Primary choice when exact 0.895" (22.73mm) height specification is required
• Preferred for applications with tight vertical clearance constraints
• Recommended when design documentation explicitly references ELM 4 series

ELM 5-23MM Selection Criteria:

• Acceptable alternative when 0.015" (0.38mm) height increase is accommodated by PCB layout
• Suitable for applications where inventory availability or lead time optimization is prioritized
• Compatible with designs permitting minor vertical spacing adjustment
• Both parts maintain identical ROHS3 compliance and MSL ratings, ensuring equivalent environmental performance

Both parts are Active status components manufactured by Bivar Inc., ensuring ongoing supply chain support and consistent quality standards.

Frequently Asked Questions (FAQ)

Q: Can ELM 5-23MM directly replace ELM 4-895 in existing designs?

A: ELM 5-23MM is mechanically compatible when the 0.015" (0.38mm) height difference does not violate PCB clearance or assembly constraints. Verify vertical spacing in your specific application before implementation.

Q: Are there electrical performance differences between these parts?

A: Both parts are passive mechanical standoffs for T1 LED packages. Electrical performance is determined by the LED component itself, not the standoff. No electrical differences exist.

Q: Do both parts meet the same compliance requirements?

A: Yes. Both ELM 4-895 and ELM 5-23MM are ROHS3 compliant with MSL rating of 1 (Unlimited), meeting identical environmental and regulatory standards.

Q: What is the significance of the height difference?

A: The 0.015" (0.38mm) difference represents a 1.7% variation from nominal. This is within standard mechanical tolerance for LED standoff applications but must be evaluated against specific PCB layout requirements.

Q: Are both parts available in the same packaging format?

A: Yes. Both parts are supplied in Bag packaging, maintaining consistent handling and storage requirements.

Q: Which part should be selected for new designs?

A: Selection depends on design specifications. If 0.895" height is explicitly required, use ELM 4-895. If design permits height variation within tolerance, either part is acceptable based on availability and lead time considerations.
