ELM 1-520 LED Standoff Equivalent & Substitute Parts

Part Overview

The ELM 1-520 is a T1 3/4 LED standoff manufactured by Bivar Inc., featuring a black PVC construction with a 0.520" (13.21mm) length. This component is classified as an active product and serves as a mechanical mounting solution for LED applications requiring vertical orientation. Substitute parts are identified based on matching electrical and mechanical parameters including LED type, material composition, color, and dimensional tolerances within the ELM series and compatible alternative series.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ELM 1-520 are qualified based on the following criteria:

Primary Substitution Parameters:

• LED Type: T1 3/4 (all substitutes match)
• Color: Black (all substitutes match)
• Manufacturer: Bivar Inc. (primary substitutes) or equivalent manufacturer (secondary substitutes)
• Material: PVC or Nylon (both acceptable for mechanical standoff function)
• RoHS Compliance: ROHS3 Compliant (all substitutes match)

Length Tolerance Consideration: Substitute parts are grouped by length variation from the main part specification. The ELM 1-520 operates at 0.520" (13.21mm). Acceptable substitutes include parts with lengths ranging from 0.500" to 0.545", representing dimensional variations within the ELM series design envelope.

Series Compatibility:

• ELM 1 Series: Direct series equivalents (ELM 1-13MM, ELM 1-545)
• ELM 3 Series: Alternative series with matching LED type and material (ELM 3-500)
• H-278C Series: Alternative series with material variation to Nylon (H-278C-2)

Parameter Comparison

Engineering Selection Recommendations

ELM 1 Series Substitutes (ELM 1-13MM, ELM 1-545): These parts maintain identical material composition (PVC), LED type, color, and RoHS compliance as the main part. Selection between these options depends on application-specific length requirements. ELM 1-13MM provides a 0.010" shorter profile (12.95mm), while ELM 1-545 provides a 0.025" longer profile (13.84mm). Both maintain active product status and ROHS3 compliance.

ELM 3-500 Substitute: This part matches all critical parameters (LED type, color, RoHS compliance, material) and represents an alternative series option. The 0.500" (12.70mm) length is 0.020" shorter than the main part. This substitute is suitable where series flexibility is acceptable and inventory availability is a consideration.

H-278C-2 Substitute: This part differs in material composition (Nylon instead of PVC) while maintaining T1 3/4 LED type, black color, and ROHS3 compliance. The 0.500" (12.70mm) length matches ELM 3-500. This substitute is applicable in applications where Nylon material properties are acceptable or preferred.

All substitute parts carry active product status and ROHS3 compliance certification, qualifying them for equivalent functional use within the specified parameter envelope.

Frequently Asked Questions (FAQ)

Q: What determines if a part can substitute for the ELM 1-520?

A: Substitution is determined by matching the following parameters: LED type (T1 3/4), color (Black), RoHS compliance (ROHS3), and manufacturer (Bivar Inc. or equivalent). Length variations within the 0.500" to 0.545" range are acceptable based on the design envelope of the ELM series.

Q: Can I use H-278C-2 as a direct replacement for ELM 1-520?

A: H-278C-2 is functionally equivalent for T1 3/4 LED standoff applications. The primary difference is material composition (Nylon vs. PVC). This substitute is applicable where Nylon material properties meet application requirements.

Q: What is the length difference between ELM 1-520 and its closest substitute?

A: ELM 1-13MM is the closest length match at 0.510" (12.95mm), representing a 0.010" (0.26mm) reduction from the main part's 0.520" (13.21mm) specification.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts carry ROHS3 compliance certification, matching the main part's regulatory status.

Q: What is the inventory availability difference between the main part and substitutes?

A: The main part ELM 1-520 has 959 units in stock. Substitute parts show higher availability: ELM 1-13MM (20735 units), ELM 1-545 (20121 units), ELM 3-500 (32418 units), and H-278C-2 (1446 units).

Q: Can I mix ELM 1 series and ELM 3 series parts in the same application?

A: Both series maintain identical LED type (T1 3/4), color (Black), and RoHS compliance. Series selection depends on application-specific requirements and design specifications.

Q: What is the Moisture Sensitivity Level for all parts?

A: ELM 1-520, ELM 1-13MM, ELM 1-545, and ELM 3-500 all carry MSL 1 (Unlimited). H-278C-2 carries MSL Not Applicable due to its Nylon material composition.
