ELM 3-495 LED Standoff Equivalent & Substitute Parts

Part Overview

The ELM 3-495 is a T1 3/4 LED standoff manufactured by Bivar Inc., designed for vertical mounting applications with a 0.495" (12.57mm) length. This component features a black PVC construction and accommodates standard T1 3/4 LED packages. The part maintains Active product status and is ROHS3 compliant, making it suitable for current production environments. Substitute parts are identified when equivalent functional performance can be achieved through alternative designs that maintain critical electrical and mechanical parameters while offering different material compositions, length tolerances, or series designations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ELM 3-495 is determined by the following critical parameters:

LED Type Compatibility: All substitute parts must accommodate T1 3/4 LED packages, ensuring mechanical fit within the standoff cavity.

Mounting Configuration: All substitutes maintain vertical mounting orientation, preserving PCB assembly compatibility.

Color Specification: All substitutes are black, maintaining visual consistency in assembled products.

Length Tolerance: Substitute parts fall within a 0.495" to 0.510" length range (12.57mm to 12.95mm), representing acceptable dimensional variation for standoff applications.

Material Composition: Substitutes utilize either PVC or Nylon construction, both providing equivalent mechanical support and electrical isolation properties.

Regulatory Compliance: All substitutes maintain ROHS3 compliance and are manufactured by Bivar Inc., ensuring consistent quality and certification status.

The three identified substitutes—ELM 3-500, ELM 1-13MM, and H-278C-2—meet these criteria while offering variations in series designation, material composition, and exact length specifications.

Parameter Comparison

Engineering Selection Recommendations

ELM 3-500: This substitute shares the ELM 3 series designation with the primary part and maintains identical PVC material composition. The length difference of 0.005" (0.13mm) represents a minimal dimensional variance within acceptable standoff tolerances. This part is recommended for applications where series consistency is preferred and inventory availability is a consideration, with 32,418 units in stock.

ELM 1-13MM: This substitute belongs to the ELM 1 series and represents the maximum length variant at 0.510" (12.95mm), a 0.015" (0.38mm) increase from the primary part. PVC material composition remains consistent. This option is suitable for applications requiring extended standoff height and is available in high inventory quantity (20,735 units).

H-278C-2: This substitute utilizes Nylon material instead of PVC while maintaining the 0.500" (12.70mm) length specification. Nylon construction provides alternative mechanical properties and is classified as Not Applicable for Moisture Sensitivity Level. This part is appropriate for applications where material substitution is acceptable and is available in limited inventory (1,446 units).

All substitutes maintain Active product status and ROHS3 compliance, ensuring compatibility with current manufacturing and regulatory requirements.

Frequently Asked Questions (FAQ)

Q: What is the primary difference between ELM 3-495 and ELM 3-500?

A: The primary difference is length specification. ELM 3-495 measures 0.495" (12.57mm), while ELM 3-500 measures 0.500" (12.70mm). Both utilize PVC material and belong to the ELM 3 series. The 0.005" difference is within acceptable tolerance for most standoff applications.

Q: Can ELM 1-13MM be used as a direct replacement for ELM 3-495?

A: ELM 1-13MM is functionally equivalent for T1 3/4 LED mounting but features a longer standoff height of 0.510" (12.95mm) compared to 0.495" (12.57mm). Series designation differs (ELM 1 versus ELM 3). Substitution is valid when the increased height does not conflict with PCB assembly constraints.

Q: What are the implications of using H-278C-2 with Nylon material instead of PVC?

A: H-278C-2 provides equivalent mechanical support and electrical isolation through Nylon construction. Nylon offers different material properties compared to PVC, including alternative thermal and chemical resistance characteristics. The Moisture Sensitivity Level classification differs (Not Applicable versus 1 Unlimited). Substitution is appropriate when material composition change is acceptable for the application environment.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. ELM 3-495, ELM 3-500, ELM 1-13MM, and H-278C-2 are all ROHS3 compliant, ensuring compatibility with regulatory requirements for current production environments.

Q: What inventory considerations should influence substitute selection?

A: ELM 3-500 offers 32,418 units in stock, ELM 1-13MM provides 20,735 units, and H-278C-2 has 1,446 units available. Inventory levels may influence selection when supply chain continuity is a consideration.

Q: Do all substitutes accommodate the same LED package type?

A: Yes. All substitute parts are designed for T1 3/4 LED packages, ensuring mechanical compatibility with standard LED components.
