ELM 3-485 Equivalent & Substitute Parts

Part Overview

The ELM 3-485 is a T1 3/4 LED standoff manufactured by Bivar Inc., designed for vertical mounting applications with a 0.485" (12.32mm) height. It is constructed from black PVC material and is ROHS3 compliant. The product is active in inventory with 895 pieces in stock. Equivalent and substitute parts become necessary when the primary part is unavailable, when application-specific material requirements demand alternatives, or when design specifications allow for minor dimensional variations within tolerance ranges.

Substitute Part Grouping Explanation

Substitute parts for the ELM 3-485 are qualified based on the following parameters: LED type compatibility (T1 3/4), material composition (PVC or equivalent polymeric material), color match (black), RoHS3 compliance, and mechanical fit within the dimensional tolerance range. The primary substitutes identified are:

ELM 3-500: Differs from the main part by 0.015" (0.38mm) in height, with identical LED type, material (PVC), color, and compliance ratings.

H-278C-2: Shares LED type and color specifications, with matching height to ELM 3-500, but differs in material composition (nylon instead of PVC) and has a different series designation.

All substitute parts maintain ROHS3 compliance and the same T1 3/4 LED footprint required for mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain active product status and ROHS3 compliance, qualifying them for equivalent substitution based on regulatory and compliance criteria. ELM 3-500 presents the closest parametric match to ELM 3-485, maintaining identical material composition and differing only in height by 0.015". H-278C-2 offers an alternative with nylon material substitution while maintaining the same final height as ELM 3-500. Selection among these parts should be based on specific mechanical clearance requirements and material preference for the target application.

Frequently Asked Questions (FAQ)

Q: What is the primary difference between ELM 3-485 and ELM 3-500? A: The parts differ in height specification: ELM 3-485 is 0.485" (12.32mm) while ELM 3-500 is 0.500" (12.70mm). Both use identical PVC material and accommodate T1 3/4 LEDs.

Q: Can H-278C-2 be used as a direct replacement for ELM 3-485? A: H-278C-2 matches the height of ELM 3-500 (0.500") and uses nylon instead of PVC material. It is compatible with T1 3/4 LEDs and is ROHS3 compliant. Material compatibility with your specific application must be verified before substitution.

Q: Are all substitute parts RoHS compliant? A: Yes, ELM 3-485, ELM 3-500, and H-278C-2 are all ROHS3 compliant, meeting current regulatory requirements for electronic component procurement.

Q: What are the inventory levels for these parts? A: ELM 3-485 has 895 pieces in stock, ELM 3-500 has 32,418 pieces in stock, and H-278C-2 has 1,446 pieces in stock.

Q: Does material composition affect substitution suitability? A: Material composition (PVC versus nylon) affects chemical resistance, thermal properties, and mechanical characteristics. ELM 3-500 maintains the PVC material of ELM 3-485, while H-278C-2 substitutes nylon material. Application-specific requirements determine whether material substitution is acceptable.
