ELM 1-490 LED Standoff Equivalent & Substitute Parts

Part Overview

The ELM 1-490 is a T1 3/4 LED standoff manufactured by Bivar Inc., featuring a black PVC construction with a 0.490" (12.45mm) length. This component is classified as an active product and is RoHS3 compliant. LED standoffs serve as mechanical mounting and alignment solutions for T1 3/4 LED packages in electronic assemblies. Substitute parts are identified when equivalent functional performance can be achieved through alternative part numbers that maintain compatibility with the same LED package type and core mechanical specifications.

Substitute Part Grouping Explanation

Substitute parts for the ELM 1-490 are qualified based on the following criteria:

Primary Compatibility Parameters:

• LED package type: T1 3/4 (all substitutes maintain this specification)
• Color: Black (all substitutes maintain this specification)
• RoHS3 compliance (all substitutes maintain this certification)
• Moisture Sensitivity Level: 1 or Not Applicable (all substitutes meet or exceed this requirement)

Allowable Variation Parameters:

• Length: 0.490" to 0.510" (12.45mm to 12.95mm range)
• Material: PVC or Nylon (both are acceptable base materials for this application)
• Series: ELM 1 or ELM 3 or H-278C (different product lines within the same manufacturer)

All three substitute parts maintain the core functional requirements of the ELM 1-490 while operating within the specified parameter tolerances.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts maintain active product status and RoHS3 compliance, ensuring continued availability and regulatory conformance. The ELM 1-490, ELM 1-13MM, and ELM 3-500 are constructed from PVC and operate within a 0.020" (0.50mm) length tolerance band. The H-278C-2 provides an alternative using nylon material while maintaining the same 0.500" (12.70mm) length as the ELM 3-500.

Selection between PVC-based substitutes (ELM 1-13MM, ELM 3-500) and the nylon-based alternative (H-278C-2) depends on material compatibility requirements within the target assembly. All parts are classified as Moisture Sensitivity Level 1 or Not Applicable, indicating no special moisture handling precautions are required during storage or assembly.

Frequently Asked Questions (FAQ)

Q: Can ELM 1-13MM be used as a direct replacement for ELM 1-490?

A: ELM 1-13MM is a parametric equivalent with a 0.020" (0.50mm) length difference (0.510" versus 0.490"). Both maintain identical LED type (T1 3/4), material (PVC), color (Black), and compliance certifications. Substitution is valid when the 0.020" length variation is acceptable within the mechanical design constraints.

Q: What is the difference between ELM 3-500 and ELM 1-13MM?

A: Both parts share identical length (0.500"), LED type (T1 3/4), material (PVC), and color (Black). The primary difference is the product series designation (ELM 3 versus ELM 1). Both are active products with equivalent compliance status.

Q: Why is H-278C-2 listed as a substitute if it uses nylon instead of PVC?

A: H-278C-2 maintains all critical functional parameters: T1 3/4 LED compatibility, black color, 0.500" length, and RoHS3 compliance. Nylon is an acceptable alternative material for this application. The Moisture Sensitivity Level classification differs (Not Applicable versus 1), but this does not restrict substitution eligibility.

Q: Are there inventory considerations when selecting a substitute?

A: Inventory levels are provided for reference: ELM 1-490 (1,002 pcs), ELM 1-13MM (20,735 pcs), ELM 3-500 (32,418 pcs), and H-278C-2 (1,446 pcs). Availability should be evaluated based on project lead time requirements.

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

A: All parts in this equivalency group are supplied in bag packaging, consistent with the main part specification.
