ELM 2-945 LED Standoff Equivalent & Substitute Parts

Part Overview

The ELM 2-945 is a T1 LED standoff manufactured by Bivar Inc., designed for vertical mounting applications with a 0.945" (24.00mm) length. This component is constructed from black PVC material and accommodates 3MM LED configurations with 2-lead connections. The part maintains Active product status and is ROHS3 compliant, making it suitable for current production environments.

Substitute parts are identified when equivalent electrical and mechanical parameters align within the allowed specifications for T1 LED standoff applications, enabling component interchangeability in compatible circuit designs.

Substitute Part Grouping Explanation

Substitute parts for the ELM 2-945 are identified based on the following critical parameters that determine functional equivalence:

Primary Substitution Criteria:

• LED Type: T1 configuration
• Material: Black PVC construction
• LED Configuration: 3MM 2-Lead mounting
• Color: Black
• RoHS Compliance: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)
• Manufacturer: Bivar Inc.

The ELM 5-23MM qualifies as a parametric equivalent because it maintains identical specifications across all critical electrical and mechanical parameters. The length differential (0.945" versus 0.910") falls within the tolerance range for T1 LED standoff applications where vertical mounting height variations of this magnitude do not affect functional compatibility in standard circuit board layouts.

Parameter Comparison

Engineering Selection Recommendations

Both the ELM 2-945 and ELM 5-23MM maintain Active product status with full ROHS3 compliance and unlimited moisture sensitivity ratings. Selection between these parts should be based on:

Inventory Availability: ELM 2-945 has 1,056 pieces in stock; ELM 5-23MM has 7,087 pieces in stock.

Length Specification: The 0.035" (0.89mm) length difference between parts must be evaluated against specific circuit board layout requirements and vertical clearance constraints in the target application.

Series Designation: ELM 2-945 belongs to the ELM 2 series (base product ELM2-9); ELM 5-23MM belongs to the ELM 5 series (base product ELM5-2). Series selection may be driven by design documentation or procurement specifications.

Both parts carry identical regulatory classifications (ECCN: EAR99; HTSUS: 3926.90.9985) and are suitable for direct substitution where mechanical height tolerances permit.

Frequently Asked Questions (FAQ)

Q: Can ELM 5-23MM be used as a direct replacement for ELM 2-945?

A: Yes, ELM 5-23MM qualifies as a parametric equivalent. Both parts share identical LED type (T1), material (Black PVC), LED configuration (3MM 2-Lead), color, and compliance ratings. The 0.035" length difference must be evaluated against specific circuit board layout requirements.

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

A: The ELM 2-945 measures 0.945" (24.00mm) while ELM 5-23MM measures 0.910" (23.11mm). This 0.89mm difference affects vertical standoff height. Applications with tight vertical clearance constraints or specific height requirements must account for this variation.

Q: Are both parts ROHS3 compliant?

A: Yes. Both ELM 2-945 and ELM 5-23MM carry ROHS3 Compliant status and are suitable for applications requiring RoHS compliance.

Q: What is the moisture sensitivity level for these parts?

A: Both parts have Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.

Q: Do these parts come in different packaging options?

A: Both parts are supplied in Bag packaging. No alternative packaging formats are specified for these part numbers.

Q: Which part should be selected based on availability?

A: ELM 5-23MM has significantly higher inventory (7,087 pieces) compared to ELM 2-945 (1,056 pieces). If length tolerance permits, ELM 5-23MM may offer better supply chain continuity.

Q: Are there any electrical differences between these parts?

A: No. Both parts are mechanical standoffs for T1 LED mounting and carry identical electrical specifications. Differences are limited to physical dimensions and series designation.
