ELM 2-645 LED Standoff Equivalent & Substitute Parts

Part Overview

The ELM 2-645 is a T1 LED standoff manufactured by Bivar Inc., designed for vertical mounting applications with a 0.645" (16.38mm) length. This component is an active product with ROHS3 compliance and MSL Level 1 rating. Substitute parts are identified when equivalent electrical and mechanical parameters align with the original specification, enabling direct replacement in applications where dimensional tolerance and form factor compatibility are maintained.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ELM 2-645 is determined by the following parameters:

• Manufacturer: Bivar Inc. (same manufacturer ensures design consistency)
• Series: ELM 2 (same product family)
• LED Type: T1 (identical LED form factor)
• Material: PVC (same material composition)
• Color: Black (identical color specification)
• Mounting Style: Vertical (same orientation requirement)
• RoHS Status: ROHS3 Compliant (regulatory equivalence)
• Moisture Sensitivity Level: 1 (Unlimited) (same environmental rating)

Length variations within the ELM 2 series are permitted substitutes when the dimensional difference accommodates the application's mechanical tolerance. The ELM 2-645, ELM 2-665, and ELM 2-17MM all meet these core substitution criteria.

Parameter Comparison

Engineering Selection Recommendations

All three parts—ELM 2-645, ELM 2-665, and ELM 2-17MM—are active products with ROHS3 compliance and MSL Level 1 ratings. Selection between these parts is determined by mechanical fit requirements within the application's dimensional tolerance.

The ELM 2-645 (0.645" / 16.38mm) is the primary specification. The ELM 2-665 (0.665" / 16.89mm) and ELM 2-17MM (0.670" / 17.02mm) represent length variants within the same product family. Substitution is valid when the application's mechanical design accommodates the length differential of 0.020" (0.51mm) between ELM 2-645 and ELM 2-665, or 0.025" (0.64mm) between ELM 2-645 and ELM 2-17MM.

All parts maintain identical electrical and environmental specifications, ensuring functional equivalence in LED standoff applications.

Frequently Asked Questions (FAQ)

Q: Can ELM 2-665 directly replace ELM 2-645?

A: Yes, when the application's mechanical tolerance accommodates a 0.020" (0.51mm) length increase. Both parts share identical material, color, LED type, mounting style, and compliance ratings.

Q: What is the primary difference between these substitute parts?

A: Length is the only dimensional difference. ELM 2-645 measures 0.645" (16.38mm), ELM 2-665 measures 0.665" (16.89mm), and ELM 2-17MM measures 0.670" (17.02mm). All other parameters are equivalent.

Q: Are all three parts ROHS3 compliant?

A: Yes. ELM 2-645, ELM 2-665, and ELM 2-17MM are all ROHS3 compliant with MSL Level 1 ratings.

Q: Does packaging differ between these parts?

A: No. All three parts are supplied in Bag packaging.

Q: Can these parts be used interchangeably in all applications?

A: Interchangeability depends on the application's mechanical design tolerance. The length variants must fit within the available space and mounting constraints of the specific application.
