ELM 3-255 LED Standoff Equivalent & Substitute Parts

Part Overview

The ELM 3-255 is a T1 3/4 LED standoff manufactured by Bivar Inc., designed for vertical mounting applications with a 0.255" (6.48mm) length specification. This component is constructed from black PVC material and features a self-retaining design suitable for 5mm LED configurations with 3-lead support.

The ELM 3-255 maintains Active product status and is ROHS3 compliant with unlimited moisture sensitivity rating (MSL 1). Substitute parts are identified when dimensional, material, or functional specifications align within acceptable tolerances for the intended application, or when inventory availability requires alternative sourcing from the same manufacturer's product line.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ELM 3-255 are identified based on the following criteria:

Primary Substitution Parameters:

• LED Type: T1 3/4 (must match)
• Material: Black PVC (must match)
• Mounting Style: Vertical Self-Retaining (must match)
• Lead Configuration: 3-Lead (must match)
• Manufacturer: Bivar Inc. (same manufacturer line)
• RoHS Compliance: ROHS3 Compliant (must match)
• MSL Rating: 1 (Unlimited) (must match)

Secondary Consideration:

• Length Tolerance: Dimensional variation within 0.005" (0.127mm) of primary specification

The ELM 3-255 (0.255" length) has two identified substitutes within the Bivar Inc. product portfolio that maintain identical functional and material specifications while varying only in length dimension. Both substitute parts maintain the same LED type, material composition, mounting configuration, and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

ELM 3-250 Substitution: The ELM 3-250 is a direct series equivalent within the ELM 3 product line. It maintains identical specifications to the ELM 3-255 across all functional, material, and compliance parameters. The sole difference is a 0.005" (0.127mm) reduction in length. This part is suitable for applications where the reduced standoff height is compatible with PCB layout and component clearance requirements. ELM 3-250 carries Active product status with ROHS3 compliance and unlimited MSL rating.

ELM 1-250 Substitution: The ELM 1-250 represents a cross-series alternative from the ELM 1 product line. It maintains identical LED type, material, mounting style, lead configuration, and compliance certifications as the ELM 3-255. The ELM 1-250 operates at the same 0.250" length as the ELM 3-250. This part is suitable for applications where series designation is not a critical design parameter and dimensional compatibility is the primary requirement. ELM 1-250 carries Active product status with ROHS3 compliance and unlimited MSL rating.

Both substitute parts are manufactured by Bivar Inc. and maintain full compliance with ROHS3 standards and environmental specifications identical to the primary part.

Frequently Asked Questions (FAQ)

Q: What is the primary difference between ELM 3-255 and its substitutes?

A: The ELM 3-255 has a length of 0.255" (6.48mm), while both substitute parts (ELM 3-250 and ELM 1-250) have a length of 0.250" (6.35mm). All other specifications including LED type, material, mounting style, lead configuration, and compliance certifications are identical.

Q: Can ELM 3-250 be used as a direct replacement for ELM 3-255?

A: ELM 3-250 can be used as a substitute when the 0.005" (0.127mm) reduction in standoff height is compatible with the application's PCB layout, component spacing, and clearance requirements. Both parts are from the same ELM 3 series and maintain identical functional specifications.

Q: What is the difference between ELM 3-250 and ELM 1-250?

A: Both parts have identical length (0.250"), LED type (T1 3/4), material (Black PVC), and compliance specifications. The primary difference is the product series designation: ELM 3-250 belongs to the ELM 3 series while ELM 1-250 belongs to the ELM 1 series. Series designation may be relevant for design documentation or supplier consistency requirements.

Q: Are all three parts ROHS3 compliant?

A: Yes. The ELM 3-255, ELM 3-250, and ELM 1-250 are all ROHS3 compliant with MSL rating of 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.

Q: What packaging format is used for these parts?

A: All three parts are supplied in Bag packaging format suitable for component distribution and assembly operations.

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

A: Interchangeability depends on the specific application's dimensional requirements. The 0.005" length difference between ELM 3-255 and the substitute parts must be evaluated against PCB design constraints, component clearance specifications, and mechanical assembly requirements. Functional performance across all three parts is equivalent when dimensional compatibility is confirmed.
