ELM 3-355 LED Standoff Equivalent and Substitute Parts

Part Overview

The ELM 3-355 is a T1 3/4 LED standoff manufactured by Bivar Inc., designed for vertical mounting applications with a 0.355" (9.02mm) height. This active product is constructed from black PVC material and is ROHS3 compliant. Finding equivalent or substitute parts may be necessary for design optimization, supply chain considerations, or application-specific mounting height requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ELM 3-355 is determined by the following key parameters:

Critical Parameters for Substitution:

• LED Type: T1 3/4 (must remain constant)
• Material: Black PVC (must remain constant)
• Color: Black (must remain constant)
• Mounting Configuration: Vertical mounting (SR VERT)

Variable Parameter:

• Length (Height): Allowable variance from 0.350" to 0.370"

The identified substitute parts maintain identical LED type, material, color, and mounting orientation specifications. Substitution is permissible when length variations fall within the specified range of 0.350" (8.89mm) to 0.370" (9.40mm), accommodating minor PCB mounting height differences and design tolerance requirements.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts—ELM 1-350 and ELM 3-370—maintain active product status with full ROHS3 compliance and unlimited moisture sensitivity level rating, confirming suitability for equivalent applications.

ELM 1-350: Provides the minimum allowable mounting height of 0.350" (8.89mm). Selection is appropriate where reduced standoff height is compatible with board layout and component clearance requirements.

ELM 3-370: Provides the maximum allowable mounting height of 0.370" (9.40mm). Selection is appropriate where increased standoff height accommodates design requirements or compensates for PCB variations.

Both substitute parts share identical LED type, material composition, color specification, and regulatory compliance with the ELM 3-355, enabling direct substitution within the specified height tolerance range.

Frequently Asked Questions (FAQ)

Q: Can the ELM 3-355 be substituted with the ELM 1-350 or ELM 3-370? A: Yes. Both parts maintain identical LED type (T1 3/4), material (black PVC), color (black), and mounting configuration (vertical). Substitution is permissible when the height variance of ±0.015" from the nominal 0.355" specification is acceptable for the application.

Q: What is the difference between the ELM 3-355 and ELM 1-350? A: The primary difference is mounting height. The ELM 1-350 has a nominal length of 0.350" (8.89mm), which is 0.005" shorter than the ELM 3-355. Both parts are otherwise identical in LED type, material, color, and compliance specifications.

Q: What is the difference between the ELM 3-355 and ELM 3-370? A: The primary difference is mounting height. The ELM 3-370 has a nominal length of 0.370" (9.40mm), which is 0.015" taller than the ELM 3-355. Both parts remain identical in LED type, material, color, mounting configuration, and regulatory compliance.

Q: Does the packaging differ between substitute parts? A: No. All parts—ELM 3-355, ELM 1-350, and ELM 3-370—are supplied in bag packaging.

Q: Are all substitute parts ROHS3 compliant? A: Yes. The ELM 3-355, ELM 1-350, and ELM 3-370 are all ROHS3 compliant with MSL 1 (Unlimited) ratings, confirming equivalent regulatory and environmental compliance.

Q: How do I select the correct substitute part based on my application? A: Selection depends on the available mounting height required by your board layout. The ELM 1-350 accommodates designs requiring reduced height. The ELM 3-370 accommodates designs requiring increased height. The ELM 3-355 represents the midpoint specification. All three parts are mechanically and electrically equivalent within their specified dimension tolerances.
