ELM 1-525 Equivalent & Substitute Parts Reference

Part Overview

The ELM 1-525 is a T1 3/4 LED standoff manufactured by Bivar Inc., designed for vertical mounting applications. This component features a black PVC construction with a 0.525" (13.34mm) length specification. The part is actively produced and maintains ROHS3 compliance with MSL 1 (Unlimited) moisture sensitivity rating. Alternative models become necessary when specific application requirements demand different length specifications, material properties, or series availability to meet design constraints or supply chain considerations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ELM 1-525 is determined by the following critical parameters:

Primary Matching Criteria:

• LED type: T1 3/4 (all substitutes maintain this specification)
• Color: Black (all substitutes maintain this specification)
• Mounting orientation: Vertical (all substitutes maintain this specification)

Secondary Variation Parameters:

• Length specification: Range from 0.500" to 0.545" (±0.020" tolerance band relative to main part)
• Material: PVC or Nylon (both materials are acceptable alternatives)
• Series: ELM 1 or ELM 3 (both series maintain identical electrical and mechanical compatibility)

All four substitute parts maintain the core T1 3/4 LED form factor and black color specification. Substitution is valid when length variation does not exceed the application's mechanical envelope requirements. The inclusion of nylon material alternatives (H-278C-2) reflects equivalent functional performance with different material properties.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts maintain active product status and ROHS3 compliance, qualifying them for direct substitution where mechanical envelope constraints are satisfied. The ELM 1-13MM, ELM 1-545, and ELM 3-500 maintain identical PVC material construction with MSL 1 ratings. The H-278C-2 presents a nylon material alternative with equivalent electrical performance but different moisture sensitivity classification (Not Applicable due to material composition).

Length variation represents the primary selection criterion. ELM 3-500 and H-278C-2 both provide the shortest length specification at 0.500" (12.70mm), suitable for applications requiring minimal vertical extension. ELM 1-545 provides maximum length at 0.545" (13.84mm). ELM 1-13MM at 0.510" (12.95mm) offers intermediate length specification. Selection is determined by available mounting space and mechanical design requirements.

PVC material is standard across the ELM series, while nylon material (H-278C-2) offers alternative mechanical properties. Material selection depends on application-specific environmental exposure and mechanical stress considerations.

Frequently Asked Questions (FAQ)

What determines if a part can substitute for the ELM 1-525?

Substitution eligibility requires matching LED type (T1 3/4), color (black), and mounting orientation (vertical). Length variation within the provided length range is acceptable where application design permits.

How do the length differences affect compatibility?

The available substitutes span lengths from 0.500" to 0.545", creating a 0.045" variation band. Applications with fixed vertical mounting clearances must account for this difference. ELM 1-525 at 0.525" occupies the mid-range of available lengths.

What is the difference between PVC and nylon material options?

ELM series parts use PVC construction with MSL 1 (Unlimited) moisture sensitivity rating. The H-278C-2 nylon alternative maintains equivalent T1 3/4 LED compatibility with different material properties suitable for specific environmental requirements.

Are all substitutes from Bivar Inc.?

All listed substitutes are manufactured by Bivar Inc., maintaining consistent quality and compliance standards.

What compliance standards apply to all available options?

All main and substitute parts maintain ROHS3 compliance and EAR99 ECCN classification. MSL ratings apply to PVC-based options (ELM series) with rating of 1 (Unlimited).

Does the series designation (ELM 1 versus ELM 3) affect electrical performance?

Series designation reflects design iteration and manufacturing line differentiation. ELM 1 and ELM 3 series maintain compatible mechanical envelopes and T1 3/4 LED specifications.
