ELM 1-825 Equivalent & Substitute Parts

Part Overview

The ELM 1-825 is a T1 3/4 LED standoff manufactured by Bivar Inc., designed for vertical mounting applications. This component is a black PVC standoff with a nominal length of 0.825" (20.96mm) and is classified as an active product with ROHS3 compliance. The need for equivalent and substitute parts arises from inventory management, supply chain continuity, and application-specific dimensional tolerances in LED mounting solutions.

Key Parameters

Substitute Part Grouping Explanation

Substitution validity for the ELM 1-825 is determined by the following critical parameters:

• LED Type: T1 3/4 (form factor compatibility)
• Material and Color: Black PVC (mechanical and aesthetic consistency)
• Series Alignment: ELM 1 (design compatibility within product family)
• RoHS and Environmental Compliance: ROHS3 Compliant with MSL 1 (regulatory and reliability requirements)
• Length Tolerance: Nominal dimensions within 0.825" with allowable manufacturing variance

The substitute part ELM 1-820 qualifies as an equivalent because it maintains all critical parameters while offering a length specification of 0.820" (20.83mm). This 0.005" (0.13mm) dimensional difference falls within standard manufacturing tolerances for mechanical components of this category and does not compromise functional compatibility in typical LED standoff applications.

Parameter Comparison

Engineering Selection Recommendations

Both the ELM 1-825 and ELM 1-820 are active products manufactured by Bivar Inc. within the ELM 1 series. Both parts achieve ROHS3 compliance and carry identical MSL ratings, ensuring equivalent environmental and regulatory performance in applications requiring lead-free materials.

The ELM 1-820 provides increased inventory availability (1983 units versus 893 units) while maintaining full compliance with the core mechanical and electrical specifications. The 0.005" (0.13mm) length differential between parts is a standard manufacturing tolerance variance and does not introduce compatibility issues in typical LED standoff mounting applications where tolerance stack-up does not exceed specified limits.

Frequently Asked Questions (FAQ)

Q: What makes the ELM 1-820 a suitable substitute for the ELM 1-825?

A: Both parts are manufactured by Bivar Inc. within the ELM 1 series, feature identical LED type (T1 3/4), material composition (Black PVC), and regulatory compliance (ROHS3 Compliant, MSL 1). The length difference of 0.005" (0.13mm) represents standard manufacturing tolerance and does not affect mechanical fit or functional performance in applications where such dimensional variance is acceptable.

Q: Are there any compatibility concerns with the dimensional difference?

A: The dimensional difference of 0.005" (0.13mm) is within standard mechanical tolerances for PVC standoff components. End-use application requirements determine whether this variance is acceptable; applications with tight tolerance stacks may require verification against specific assembly drawings.

Q: Do both parts carry the same environmental compliance ratings?

A: Yes. Both the ELM 1-825 and ELM 1-820 are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity ratings, ensuring equivalent environmental performance and regulatory suitability.

Q: What is the packaging format for these components?

A: Both the ELM 1-825 and ELM 1-820 are supplied in bag packaging, consistent with standard standoff component distribution methods.

Q: Can these parts be used interchangeably?

A: Yes, within applications where the 0.005" (0.13mm) length tolerance is acceptable. Both parts maintain the same mechanical interface (T1 3/4 LED form factor), material properties, and compliance certifications.
