ELM 3-855 LED Standoff Equivalent & Substitute Parts

Part Overview

The ELM 3-855 is a T1 3/4 LED standoff manufactured by Bivar Inc., designed for vertical mounting applications with a 0.855" (21.72mm) length. This component is constructed from black PVC material and is classified as Active product status. Substitute parts are identified when inventory constraints, lead time requirements, or design flexibility necessitate alternative components that maintain functional compatibility within the allowed electrical and mechanical parameter ranges.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ELM 3-855 are qualified based on the following criteria:

Matching Parameters (Required for Substitution):

• LED Type: T1 3/4
• Material: PVC
• Color: Black
• Mounting Style: Vertical
• Manufacturer: Bivar Inc.
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)
• Packaging: Bag

Variable Parameter (Allows Substitution):

• Length: Tolerance range permits variation within mechanical design constraints

The ELM 1-820 qualifies as a parametric equivalent because it maintains all critical matching parameters while offering a length of 0.820" (20.83mm), representing a 0.035" (0.89mm) reduction from the main part. This dimensional variation falls within acceptable mechanical tolerance for standoff applications where precise height adjustment or space constraints require alternative lengths.

Parameter Comparison

Engineering Selection Recommendations

Both the ELM 3-855 and ELM 1-820 are Active product status components manufactured by Bivar Inc. with ROHS3 compliance and MSL 1 rating. Selection between these parts is determined by mechanical length requirements specific to the application:

ELM 3-855 Selection Criteria:

• Applications requiring 0.855" (21.72mm) standoff height
• Design specifications with fixed vertical spacing constraints
• Current inventory availability: 1101 pieces

ELM 1-820 Selection Criteria:

• Applications requiring 0.820" (20.83mm) standoff height
• Design flexibility permitting 0.035" (0.89mm) height reduction
• Higher inventory availability: 1983 pieces
• Suitable for space-constrained applications

Both parts maintain identical electrical and environmental compliance characteristics. The choice between them is purely mechanical and application-dependent.

Frequently Asked Questions (FAQ)

Q: Can ELM 1-820 be used in place of ELM 3-855?

A: Yes, provided the application design permits a 0.035" (0.89mm) reduction in standoff height. Both parts share identical LED type (T1 3/4), material (PVC), color (Black), mounting style (Vertical), and compliance ratings (ROHS3, MSL 1).

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

A: The ELM 1-820 has a shorter length of 0.820" compared to the ELM 3-855 at 0.855". All other electrical, mechanical, and environmental parameters are identical.

Q: Are both parts from the same manufacturer?

A: Yes, both ELM 3-855 and ELM 1-820 are manufactured by Bivar Inc.

Q: Do these parts have different RoHS compliance levels?

A: No, both parts are ROHS3 Compliant with identical Moisture Sensitivity Level 1 (Unlimited) ratings.

Q: What packaging format is used for both parts?

A: Both parts are supplied in Bag packaging format.

Q: Can I use ELM 3-855 in place of ELM 1-820?

A: Yes, if the application design accommodates a 0.035" (0.89mm) increase in standoff height. All other parameters remain compatible.

Q: Are there any electrical differences between these parts?

A: No electrical differences exist. Both parts are mechanical standoffs for T1 3/4 LED components with identical material composition and environmental ratings.
