ELM 1-485 LED Standoff: Equivalent & Substitute Parts

Part Overview

The ELM 1-485 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 0.485" (12.32mm) length and is classified as Active product status. LED standoffs serve as mechanical and electrical positioning devices for light-emitting diodes in circuit assemblies. Substitute parts become necessary when the primary component experiences supply constraints, extended lead times, or when design specifications permit dimensional or material variations within defined tolerances.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ELM 1-485 is determined by the following critical parameters:

Primary Compatibility Criteria:

• LED Type: T1 3/4 (must match exactly)
• Color: Black (must match exactly)
• Material: PVC or equivalent polymer (Nylon acceptable as alternative)
• Length: 0.485" nominal with tolerance allowance up to 0.500" (12.70mm)
• Mounting Orientation: Vertical (SR VERT designation)
• RoHS Compliance: ROHS3 Compliant (required)

The substitute parts ELM 3-500 and H-278C-2 satisfy these criteria through matching LED type, color specification, and compliance certifications. Length variation between 0.485" and 0.500" represents a 0.015" (0.38mm) difference, which falls within acceptable mechanical tolerance for standoff applications. Material substitution from PVC to Nylon (H-278C-2) is permissible where thermal and chemical resistance requirements do not exceed Nylon specifications.

Parameter Comparison

Engineering Selection Recommendations

ELM 3-500 Selection Criteria: The ELM 3-500 maintains identical material composition (PVC) and LED type specification as the primary part. The 0.015" length increase is mechanically compatible with standard PCB mounting tolerances. Both parts carry Active product status and ROHS3 compliance. Current inventory for ELM 3-500 (32,418 pcs) significantly exceeds ELM 1-485 availability (880 pcs), making this substitute appropriate for applications where the marginal length difference does not create mechanical interference or aesthetic constraints.

H-278C-2 Selection Criteria: The H-278C-2 provides an alternative material option (Nylon vs. PVC) while maintaining T1 3/4 LED compatibility and black color specification. Nylon construction offers different thermal and chemical resistance characteristics compared to PVC. This substitute is suitable for applications where Nylon material properties align with environmental exposure conditions. The H-278C-2 carries ROHS3 compliance and REACH Unaffected status. Moisture Sensitivity Level classification differs (Not Applicable vs. Level 1), indicating different handling requirements during storage and assembly.

Frequently Asked Questions (FAQ)

Q: Can ELM 3-500 be used as a direct replacement for ELM 1-485?

A: ELM 3-500 is mechanically and electrically compatible with ELM 1-485 for T1 3/4 LED standoff applications. The 0.015" length difference (0.500" vs. 0.485") must be evaluated against specific PCB layout and mechanical assembly constraints. Both parts share identical LED type, color, material (PVC), and RoHS compliance status.

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

A: The primary difference is material composition. ELM 3-500 uses PVC, while H-278C-2 uses Nylon. Both maintain T1 3/4 LED compatibility and 0.500" length. Material selection depends on thermal exposure, chemical resistance requirements, and environmental conditions of the application.

Q: Are all three parts RoHS3 compliant?

A: Yes. ELM 1-485, ELM 3-500, and H-278C-2 all carry ROHS3 Compliant certification, meeting regulatory requirements for restricted substance elimination.

Q: Does the Moisture Sensitivity Level difference between parts affect substitution?

A: Moisture Sensitivity Level 1 (Unlimited) for ELM 1-485 and ELM 3-500 indicates minimal moisture sensitivity during storage and handling. H-278C-2 lists MSL as Not Applicable, reflecting Nylon material characteristics. This difference does not prevent substitution but indicates different storage condition requirements may apply.

Q: What packaging format is used for all substitute parts?

A: All three parts (ELM 1-485, ELM 3-500, and H-278C-2) are supplied in Bag packaging format.
