ELM 1-355 Equivalent & Substitute Parts

Part Overview

The ELM 1-355 is a T1 3/4 LED standoff manufactured by Bivar Inc., constructed from black PVC material with a length of 0.355" (9.02mm). This component is classified as an active product with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1). LED standoffs serve as mechanical and electrical mounting interfaces for LED assemblies in circuit board applications. Alternative models are necessary when specific length requirements or inventory availability constraints affect component sourcing decisions.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the ELM 1-355 is determined by the following key parameters:

• LED Type: T1 3/4 (all substitutes maintain this specification)
• Material: Black PVC (all substitutes use identical material)
• Length Tolerance: Mechanical length variation within functional mounting constraints (0.350" to 0.370")
• Product Status: Active status required for reliability
• RoHS Compliance: ROHS3 compliance maintained across all substitutes
• Moisture Sensitivity Level: MSL 1 (Unlimited) required for environmental compatibility

The substitute parts ELM 1-350 and ELM 3-370 are functionally equivalent within the allowable length variation range specified for this product category. Both parts maintain identical electrical and material specifications while providing alternative length options.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts (ELM 1-350 and ELM 3-370) maintain active product status and ROHS3 compliance, confirming their suitability for applications requiring the same environmental and regulatory standards as the primary ELM 1-355 component.

Selection between these parts is determined by mechanical length requirements for the specific PCB layout and mounting geometry. The ELM 1-350 provides 0.005" shorter length compared to the primary part, while the ELM 3-370 provides 0.015" greater length. Both alternatives are manufactured from identical material composition and support the same LED type classification.

Inventory availability differs across these parts, with ELM 1-350 showing significantly higher stock levels (12,862 units) compared to ELM 1-355 (1,015 units) and ELM 3-370 (863 units), making the ELM 1-350 the preferred sourcing option when design constraints allow for the shorter length specification.

Frequently Asked Questions (FAQ)

Q: What determines if ELM 1-350 or ELM 3-370 can replace ELM 1-355?

A: The substitute parts must share identical LED type (T1 3/4), material (Black PVC), color (Black), and compliance standards (ROHS3, MSL 1). Length variation is the only parameter that differs between parts. Substitution is valid only when mechanical design tolerances accommodate the length difference (±0.005" or ±0.015").

Q: Why do ELM 1-350 and ELM 3-370 have different series designations?

A: ELM 1-350 belongs to the ELM 1 series while ELM 3-370 belongs to the ELM 3 series. Both are functionally equivalent substitutes based on the allowable parameters for this product category, despite different base product numbers (ELM1-3 versus ELM3-3).

Q: Are there environmental or regulatory concerns when substituting parts?

A: All parts maintain identical ROHS3 compliance status and MSL 1 (Unlimited) moisture sensitivity rating. No additional environmental or regulatory validation is required when substituting between these parts.

Q: What is the primary consideration when selecting between substitute options?

A: Mechanical length compatibility with the PCB mounting hole spacing and component clearance envelope determines selection. The ELM 1-350 (0.350") is suitable for designs requiring shorter standoff height, while ELM 3-370 (0.370") accommodates designs requiring increased clearance. Inventory availability may also influence sourcing decisions.
