ELM 1-20MM LED Standoff Equivalent & Substitute Parts

Part Overview

The ELM 1-20MM 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 0.790" (20.07mm) length specification. The part maintains Active product status and is ROHS3 compliant, making it suitable for current production environments. Substitute parts are identified when inventory constraints, lead time requirements, or specific application needs necessitate alternative components that maintain functional equivalence within defined mechanical and electrical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts within the ELM 1 series are determined by the following critical parameters:

Series Consistency: All substitute parts must belong to the ELM 1 series to ensure mechanical and electrical compatibility.

LED Type Specification: The T1 3/4 LED type must remain constant across all substitutes to maintain functional equivalence in mounting and light output characteristics.

Material and Color: Black PVC construction is maintained across all substitutes to ensure consistent thermal and mechanical properties.

Mounting Orientation: Vertical (SR VERT) mounting configuration remains unchanged.

Compliance Standards: ROHS3 compliance and MSL 1 rating must be preserved to meet regulatory and environmental requirements.

Length Tolerance: Substitute parts may vary in length specification within the ELM 1 series design envelope. The ELM 1-820 represents a parametric equivalent with a length of 0.820" (20.83mm), providing a 0.030" (0.76mm) dimensional variation that remains within acceptable mechanical tolerances for vertical standoff applications.

Parameter Comparison

Engineering Selection Recommendations

Both ELM 1-20MM and ELM 1-820 maintain Active product status with ROHS3 compliance and MSL 1 rating, confirming suitability for current production applications. The dimensional difference of 0.030" (0.76mm) in length represents the primary distinction between these components. Selection between these parts should be based on specific application height requirements and PCB layout constraints. Both parts are manufactured by Bivar Inc. within the same ELM 1 series, ensuring consistent mechanical interface and electrical performance characteristics. Inventory availability may influence component selection, with ELM 1-820 currently maintaining higher stock levels (1983 Pcs) compared to ELM 1-20MM (931 Pcs).

Frequently Asked Questions (FAQ)

Q: Can ELM 1-820 be used as a direct replacement for ELM 1-20MM?

A: ELM 1-820 is a parametric equivalent within the ELM 1 series. Both components share identical LED type (T1 3/4), material (PVC), color (Black), mounting style (Vertical), and compliance ratings (ROHS3, MSL 1). The length difference of 0.030" (0.76mm) must be evaluated against specific application requirements. If the application accommodates the increased standoff height, substitution is permissible.

Q: What determines compatibility between ELM 1-20MM and ELM 1-820?

A: Compatibility is established through matching series designation (ELM 1), LED type specification (T1 3/4), material composition (PVC), color (Black), and mounting configuration (Vertical). These parameters ensure mechanical and electrical equivalence. The length variation is the only dimensional difference and must be assessed within the context of individual application constraints.

Q: Are there any compliance or regulatory differences between these parts?

A: Both ELM 1-20MM and ELM 1-820 maintain identical ROHS3 compliance status and Moisture Sensitivity Level 1 (Unlimited) rating. No regulatory or compliance distinctions exist between these components.

Q: How does packaging affect the selection between these substitute parts?

A: Both components are supplied in Bag packaging format. Packaging type does not differentiate these parts and does not affect substitution eligibility.

Q: What is the significance of the 0.030" length difference in practical applications?

A: The length difference between ELM 1-20MM (0.790") and ELM 1-820 (0.820") affects the vertical standoff height on PCB assemblies. Applications with tight vertical clearance constraints or specific height requirements must account for this dimensional variation during component selection and PCB layout design.
