ELM 3-525 LED Standoff Equivalent & Substitute Parts

Part Overview

The ELM 3-525 is a T1 3/4 LED standoff manufactured by Bivar Inc., featuring a black PVC construction with a 0.525" (13.34mm) vertical height. This component is designed for vertical LED mounting applications and maintains Active product status. Substitute parts are identified when equivalent electrical and mechanical parameters align with the original specification, enabling direct replacement in compatible applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ELM 3-525 is determined by the following parameters:

Primary Compatibility Criteria:

• LED Type: T1 3/4 (all substitutes match)
• Mounting Orientation: Vertical (all substitutes match)
• Color: Black (all substitutes match)
• RoHS Compliance: ROHS3 Compliant (all substitutes match)

Secondary Consideration:

• Length Tolerance: Substitutes range from 0.500" (12.70mm) to 0.545" (13.84mm), with the main part at 0.525" (13.34mm). Length variations of ±0.025" are within the substitute group.
• Material Variation: PVC and Nylon materials are both represented in the substitute group.

All four substitute parts meet the core electrical and mechanical requirements for T1 3/4 LED standoff applications.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts maintain Active product status and ROHS3 compliance, ensuring regulatory alignment with the original ELM 3-525 specification.

ELM 3-500: Identical series (ELM 3), PVC material, and RoHS compliance. Length difference of 0.025" (0.64mm) shorter than the main part.

ELM 1-13MM: PVC material and RoHS compliance maintained. Series change from ELM 3 to ELM 1. Length of 0.510" (12.95mm) represents 0.015" (0.38mm) shorter than the main part.

ELM 1-545: PVC material and RoHS compliance maintained. Series change from ELM 3 to ELM 1. Length of 0.545" (13.84mm) represents 0.020" (0.51mm) longer than the main part.

H-278C-2: Material differs (Nylon vs. PVC). Length of 0.500" (12.70mm) matches ELM 3-500. RoHS3 compliance and T1 3/4 LED type maintained. MSL classification differs (Not Applicable vs. 1).

Selection among substitutes depends on application-specific length requirements and material compatibility constraints.

Frequently Asked Questions (FAQ)

Q: Can ELM 3-500 directly replace ELM 3-525?

A: ELM 3-500 is a parametric equivalent with identical series designation, material (PVC), and RoHS compliance. The length difference is 0.025" (0.64mm). Direct replacement is determined by application tolerance for vertical standoff height.

Q: What is the difference between ELM 3 and ELM 1 series substitutes?

A: Both series contain T1 3/4 LED standoffs in black PVC with ROHS3 compliance. The series designation reflects different product lines within Bivar Inc.'s portfolio. ELM 1-13MM and ELM 1-545 are functionally equivalent to ELM 3-525 for T1 3/4 LED mounting applications.

Q: Why is H-278C-2 listed as a substitute if the material differs?

A: H-278C-2 maintains all critical parameters: T1 3/4 LED type, vertical mounting, black color, and ROHS3 compliance. Material composition (Nylon vs. PVC) is a secondary parameter. Substitution validity depends on application requirements for material properties and environmental exposure.

Q: What length tolerance exists within the substitute group?

A: Substitute parts range from 0.500" (12.70mm) to 0.545" (13.84mm), spanning 0.045" (1.14mm) total. The main part ELM 3-525 at 0.525" (13.34mm) is positioned centrally within this range. Application-specific PCB layout and component clearance requirements determine acceptable length variation.

Q: Are all substitutes in stock?

A: Inventory status is provided for reference. ELM 3-500 maintains the highest inventory level at 32,418 pieces. Availability should be verified at the time of procurement.

Q: Do all substitutes maintain the same moisture sensitivity classification?

A: ELM 3-525, ELM 3-500, ELM 1-13MM, and ELM 1-545 all carry MSL 1 (Unlimited). H-278C-2 carries MSL classification as Not Applicable due to its Nylon material composition. This distinction does not affect substitution eligibility for standard applications.
