ELM 4-445 LED Standoff Equivalent & Substitute Parts

Part Overview

The ELM 4-445 is a T1 LED standoff manufactured by Bivar Inc., designed for vertical mounting applications with a 0.445" (11.30mm) 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 inventory constraints, lead time requirements, or design tolerance flexibility necessitate alternative components within the same functional category.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ELM 4-445 is determined by the following critical parameters:

Mandatory Matching Criteria:

• Manufacturer: Bivar Inc.
• Series: ELM 4
• LED Type: T1
• Material: Black PVC
• Configuration: Vertical Mount, 3MM, 2-Lead
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Allowable Variation:

• Length tolerance: Components within the ELM 4 series with length specifications of 0.440" to 0.445" are functionally equivalent for applications where standoff height permits minor dimensional variation.

The ELM 4-440 qualifies as a parametric equivalent based on identical material composition, LED type, mounting configuration, compliance certifications, and series designation. The 0.005" (0.12mm) length difference represents a negligible dimensional variance within standard mechanical tolerances for LED standoff applications.

Parameter Comparison

Engineering Selection Recommendations

Both the ELM 4-445 and ELM 4-440 maintain Active product status within the Bivar Inc. portfolio, ensuring continued manufacturing support and supply chain stability. Both components satisfy ROHS3 compliance requirements and carry MSL 1 (Unlimited) moisture sensitivity ratings, indicating no special storage or handling constraints for either part.

Selection between these components should be based on:

1. Mechanical Fit Requirements: The 0.005" length differential must be evaluated against PCB layout constraints and mechanical clearance specifications in the target application.

2. Inventory Availability: ELM 4-440 maintains 991 pieces in stock compared to 733 pieces for ELM 4-445, providing supply flexibility for high-volume procurement scenarios.

3. Compliance Continuity: Both parts maintain identical regulatory certifications (ROHS3, ECCN EAR99, HTSUS 3926.90.9985), ensuring no compliance impact from substitution.

Frequently Asked Questions (FAQ)

Q: Can ELM 4-440 be used as a direct replacement for ELM 4-445?

A: The ELM 4-440 is a parametric equivalent within the ELM 4 series. Substitution is valid when the 0.005" (0.12mm) length reduction does not conflict with mechanical clearance or standoff height requirements in the specific application. Design verification is required to confirm dimensional compatibility.

Q: Are there any compliance differences between these parts?

A: No. Both components carry identical RoHS3 compliance status, MSL 1 ratings, ECCN classifications, and HTSUS codes. Substitution introduces no regulatory or certification changes.

Q: What is the basis for considering these parts equivalent?

A: Equivalence is established through matching manufacturer, series, LED type, material composition, mounting configuration, lead count, and compliance certifications. The length specification represents the only dimensional variance and falls within acceptable tolerance ranges for this component category.

Q: Does packaging differ between these parts?

A: Both parts are supplied in Bag packaging format. No packaging configuration changes occur with substitution.

Q: Are there inventory or lead time advantages to selecting ELM 4-440?

A: ELM 4-440 maintains higher current stock levels (991 pieces versus 733 pieces), which may provide supply chain advantages for time-sensitive procurement requirements.
