ELM 1-500 LED Standoff Equivalent & Substitute Parts

Part Overview

The ELM 1-500 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 0.500" (12.70mm) length and is classified as an active product with ROHS3 compliance. Substitute parts are identified when equivalent electrical and mechanical parameters align with the main part specifications, enabling direct replacement in compatible applications.

Substitute Part Grouping Explanation

Substitute parts for the ELM 1-500 are identified based on the following critical parameters:

Primary Matching Criteria:

• LED Type: T1 3/4 (all substitutes match)
• Length: 0.500" (12.70mm) (primary dimension for mechanical fit)
• Color: Black (visual and application consistency)
• Product Status: Active (availability and support continuity)
• RoHS Compliance: ROHS3 Compliant (regulatory alignment)

Substitution Logic: The ELM 1-500 accepts three equivalent parts. Two substitutes (ELM 3-500 and H-278C-2) maintain identical length and LED specifications. One substitute (ELM 1-13MM) shares the same series and specifications but with a length variance of 0.010" (0.25mm), representing a minor dimensional tolerance within mechanical compatibility ranges for standoff applications.

Material variations exist among substitutes: ELM 1-13MM and ELM 3-500 use PVC (matching the main part), while H-278C-2 uses Nylon. Both materials are black and maintain equivalent mechanical function for LED mounting.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts maintain active product status and ROHS3 compliance, ensuring regulatory alignment and continued manufacturer support. Selection between substitutes depends on material and dimensional requirements:

ELM 1-13MM: Identical series (ELM 1) with 0.010" length variance. Suitable for applications where ELM 1 series consistency is required and minor dimensional tolerance is acceptable.

ELM 3-500: Exact length match (0.500") with PVC material. Represents a series upgrade within the Bivar standoff portfolio while maintaining identical mechanical dimensions.

H-278C-2: Exact length match (0.500") with Nylon material substitution. Nylon construction provides alternative material properties while preserving LED type and mounting dimensions. MSL rating is not applicable for this part.

All three substitutes are currently in active production with substantial inventory availability.

Frequently Asked Questions (FAQ)

Q: Can ELM 1-13MM replace ELM 1-500 in all applications?

A: ELM 1-13MM shares the same series and specifications as ELM 1-500 but has a length of 0.510" (12.95mm) compared to 0.500" (12.70mm). The 0.010" difference is within mechanical tolerance for most standoff applications. Verify dimensional clearance in your specific PCB layout before substitution.

Q: What is the material difference between ELM 3-500 and H-278C-2?

A: ELM 3-500 uses PVC material, matching the ELM 1-500 main part. H-278C-2 uses Nylon material. Both materials are black and support T1 3/4 LED mounting at 0.500" length. Material selection depends on environmental exposure, temperature range, and mechanical stress requirements in your application.

Q: Are all substitutes ROHS3 compliant?

A: Yes. ELM 1-13MM, ELM 3-500, and H-278C-2 are all ROHS3 compliant and REACH unaffected, matching the regulatory status of ELM 1-500.

Q: What does MSL rating mean for these parts?

A: Moisture Sensitivity Level (MSL) indicates moisture absorption characteristics during storage and handling. ELM 1-500, ELM 1-13MM, and ELM 3-500 have MSL 1 (Unlimited), meaning no moisture precautions are required. H-278C-2 has MSL Not Applicable, indicating Nylon material does not require moisture sensitivity classification.

Q: Can I use H-278C-2 as a direct replacement for ELM 1-500?

A: H-278C-2 matches the length (0.500") and LED type (T1 3/4) of ELM 1-500. The primary difference is material: Nylon instead of PVC. Both materials support identical mechanical function. Substitution is valid when Nylon material properties are compatible with your application environment.

Q: Which substitute has the highest inventory availability?

A: ELM 3-500 has 32,418 pieces in stock, followed by ELM 1-13MM with 20,735 pieces, and H-278C-2 with 1,446 pieces. ELM 1-500 has 893 pieces available.
