ELM 1-275 LED Standoff Equivalent & Substitute Parts

Part Overview

The ELM 1-275 is a T1 3/4 LED standoff manufactured by Bivar Inc., designed for vertical mounting applications. This component features a black PVC construction with a 0.275" (6.99mm) length specification. The part maintains Active product status and is ROHS3 compliant, making it suitable for current production environments. Identification of equivalent substitute parts becomes necessary when managing inventory constraints, addressing supply chain disruptions, or accommodating design tolerance requirements within the allowed mechanical and electrical parameter ranges.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ELM 1-275 is determined by the following critical parameters:

Primary Compatibility Criteria:

• LED Type: T1 3/4 (must match exactly)
• Material: Black PVC (must match exactly)
• Mounting Style: Vertical (must match exactly)
• Color: Black (must match exactly)
• RoHS Compliance: ROHS3 Compliant (must match or exceed)
• Moisture Sensitivity Level: 1 (Unlimited) (must match or be less restrictive)

Secondary Tolerance Parameter:

• Length: 0.275" (6.99mm) nominal, with allowable variance to 0.285" (7.24mm)

The ELM 3-285 qualifies as a parametric equivalent because it maintains identical specifications across all primary criteria while operating within the acceptable length tolerance range for this product category.

Parameter Comparison

Engineering Selection Recommendations

Both the ELM 1-275 and ELM 3-285 maintain Active product status with ROHS3 compliance and identical Moisture Sensitivity Level ratings. Selection between these parts should be based on:

Inventory Availability: The ELM 3-285 currently maintains higher stock levels (4749 pcs) compared to the ELM 1-275 (1027 pcs), making it suitable for high-volume production requirements.

Length Specification Tolerance: The 0.010" (0.25mm) length differential between parts falls within standard mechanical tolerance ranges for LED standoff applications. Design verification should confirm that PCB mounting hole spacing and component clearance accommodate the ELM 3-285 length specification.

Regulatory Compliance: Both parts satisfy identical compliance requirements, including ROHS3 certification and EAR99 export classification, enabling direct substitution from a regulatory standpoint.

Frequently Asked Questions (FAQ)

Q: Can the ELM 3-285 be used as a direct replacement for the ELM 1-275 in existing designs?

A: The ELM 3-285 qualifies as a parametric equivalent based on matching LED type, material, color, mounting style, and compliance certifications. The 0.010" length difference must be evaluated against specific PCB layout requirements and component clearance specifications. No design changes are required if the additional length does not conflict with board-level constraints.

Q: What is the significance of the length tolerance between these parts?

A: The ELM 1-275 specifies 0.275" (6.99mm) length while the ELM 3-285 specifies 0.285" (7.24mm) length. This 0.25mm variance is within acceptable mechanical tolerance for LED standoff applications. Verification of PCB mounting hole depth and adjacent component spacing is necessary before implementation.

Q: Are there any compliance or certification differences between these parts?

A: Both parts maintain identical RoHS3 compliance status, Moisture Sensitivity Level 1 (Unlimited) rating, and EAR99 export classification. No compliance barriers exist for substitution.

Q: What packaging format is used for both parts?

A: Both the ELM 1-275 and ELM 3-285 are supplied in Bag packaging, maintaining consistent handling and storage requirements.

Q: Which part should be selected for new production designs?

A: Selection should prioritize current inventory availability and design tolerance requirements. The ELM 3-285 offers higher stock availability. Confirm that the 0.285" length specification accommodates your specific PCB design before implementation.
