ELM 7-155 LED Standoff Equivalent & Substitute Parts

Part Overview

The ELM 7-155 is a T1 LED standoff manufactured by Bivar Inc., designed for vertical mounting applications with a 0.155" (3.94mm) length. This component is constructed from black PVC material and accommodates 2-lead configurations. The part maintains Active product status and is ROHS3 compliant, making it suitable for current production environments.

Substitute parts become necessary when the primary component experiences supply constraints, extended lead times, or inventory depletion. The ELM 7-155 has identified equivalent alternatives within the ELM series that maintain functional compatibility through standardized electrical and mechanical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ELM 7-155 is determined by the following critical parameters:

Primary Compatibility Criteria:

• Manufacturer: Bivar Inc. (same manufacturer ensures design consistency)
• LED Type: T1 (standardized form factor)
• Material: Black PVC (mechanical and environmental compatibility)
• Lead Configuration: 2-Lead (electrical interface requirement)
• Mounting Style: Vertical (PCB layout compatibility)
• RoHS Status: ROHS3 Compliant (regulatory requirement)

Secondary Consideration:

• Length tolerance: Substitute parts with 0.150" (3.81mm) length represent a 0.005" (0.13mm) reduction from the primary part specification

The identified substitutes—ELM 4-150 and ELM 5-150—share all primary compatibility criteria with the ELM 7-155. Both alternatives differ only in series designation and length specification, representing minor dimensional variations within the T1 LED standoff product family.

Parameter Comparison

Engineering Selection Recommendations

ELM 4-150 Selection Criteria:

• Inventory availability: 12,323 pieces in stock (highest availability)
• Product status: Active
• Compliance: ROHS3 compliant, REACH unaffected
• Length differential: 0.005" shorter than primary part
• Series: ELM 4

ELM 5-150 Selection Criteria:

• Inventory availability: 1,125 pieces in stock
• Product status: Active
• Compliance: ROHS3 compliant, REACH unaffected
• Length differential: 0.005" shorter than primary part
• Series: ELM 5

Both substitute parts maintain identical electrical and mechanical compatibility with the ELM 7-155 across all critical parameters. Selection between ELM 4-150 and ELM 5-150 should be based on inventory availability and supply chain requirements. The ELM 4-150 offers superior stock availability for immediate procurement needs.

Frequently Asked Questions (FAQ)

Q: Can ELM 4-150 and ELM 5-150 be used interchangeably with ELM 7-155?

A: Both substitute parts share identical electrical and mechanical specifications with the ELM 7-155, including LED type (T1), material (black PVC), lead configuration (2-lead), mounting style (vertical), and compliance certifications (ROHS3). The 0.005" length difference represents a minor dimensional variation within the T1 standoff family.

Q: What is the significance of the length difference between ELM 7-155 (0.155") and the substitute parts (0.150")?

A: The 0.005" (0.13mm) length reduction in ELM 4-150 and ELM 5-150 represents a tolerance variation within the T1 LED standoff product line. This dimensional difference must be evaluated against specific PCB layout and component clearance requirements in the target application.

Q: Are all three parts packaged identically?

A: Yes. ELM 7-155, ELM 4-150, and ELM 5-150 are all supplied in bag packaging, ensuring consistent handling and storage requirements.

Q: Do the substitute parts carry the same regulatory certifications?

A: All three parts are ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited). ELM 4-150 and ELM 5-150 additionally carry REACH unaffected status.

Q: Which substitute part should be selected for immediate availability?

A: ELM 4-150 maintains the highest inventory level at 12,323 pieces, providing optimal availability for procurement timelines requiring rapid component sourcing.
