ELM 1-845 LED Standoff Equivalent & Substitute Parts

Part Overview

The ELM 1-845 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 length of 0.845" (21.46mm) and is classified as an active product with full RoHS3 compliance. The need to identify equivalent substitute parts arises from inventory availability, lead time considerations, or specific application requirements where dimensional or performance variations are acceptable within defined parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ELM 1-845 is determined by strict adherence to the following parameters:

Critical Parameters (Must Match):

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

Variable Parameter (Allowable Tolerance):

• Length: The substitute part ELM 1-820 has a length of 0.820" (20.83mm), representing a 0.025" (0.63mm) reduction from the main part specification.

The ELM 1-820 qualifies as a parametric equivalent because it maintains all critical specifications while operating within acceptable dimensional variance for this product category.

Parameter Comparison

Engineering Selection Recommendations

Both the ELM 1-845 and ELM 1-820 are active products manufactured by Bivar Inc. within the ELM 1 series. Both components carry ROHS3 compliance certification and identical Moisture Sensitivity Level ratings, confirming equivalent environmental and regulatory standing.

The primary distinction between these parts is the length specification. The ELM 1-820 operates at a reduced length of 0.820" compared to the 0.845" specification of the main part. This dimensional difference of 0.025" (0.63mm) must be evaluated against specific application requirements, including PCB layout constraints, LED alignment tolerances, and mechanical clearance specifications.

Selection between these parts should be based on whether the application can accommodate the shorter standoff height of the ELM 1-820 without compromising functional performance or mechanical fit.

Frequently Asked Questions (FAQ)

Q: Can the ELM 1-820 be used as a direct replacement for the ELM 1-845?

A: The ELM 1-820 is a parametric equivalent within the ELM 1 series. Both parts share identical LED type, material, color, mounting style, and compliance certifications. The ELM 1-820 features a 0.025" shorter length. Compatibility depends on whether your application can function with this reduced standoff height.

Q: What is the significance of the length difference between these parts?

A: The ELM 1-845 has a length of 0.845" (21.46mm), while the ELM 1-820 measures 0.820" (20.83mm). This 0.025" (0.63mm) reduction affects the vertical spacing of the LED component. Applications with tight vertical clearance or specific LED positioning requirements must account for this dimensional variance.

Q: Are both parts RoHS compliant?

A: Yes. Both the ELM 1-845 and ELM 1-820 carry ROHS3 compliance certification, confirming equivalent environmental and regulatory status.

Q: Do these parts have the same moisture sensitivity rating?

A: Yes. Both components are rated at Moisture Sensitivity Level 1 (Unlimited), indicating identical moisture handling and storage requirements.

Q: What packaging format is used for these parts?

A: Both the ELM 1-845 and ELM 1-820 are supplied in bag packaging.

Q: Are there any other substitute options for the ELM 1-845?

A: Based on the provided data, the ELM 1-820 is the identified parametric equivalent. No additional substitute parts are specified in the reference documentation.
