ELM 1-445 LED Standoff Equivalent & Substitute Parts

Part Overview

The ELM 1-445 is a T1 3/4 LED standoff manufactured by Bivar Inc., featuring a black PVC construction with a 0.445" (11.30mm) length. This component is classified as an active product and is ROHS3 compliant. LED standoffs serve as mechanical mounting and alignment components for T1 3/4 LED packages in vertical surface-mount applications. Substitute parts are identified when equivalent electrical and mechanical parameters are maintained across the product line, enabling design flexibility and supply chain optimization.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ELM 1-445 are qualified based on the following criteria:

Primary Substitution Parameters:

• LED Type: T1 3/4 (maintained across all substitutes)
• Material: Black PVC (maintained across all substitutes)
• Mounting Style: Surface Mount Vertical (maintained across all substitutes)
• Color: Black (maintained across all substitutes)
• RoHS Status: ROHS3 Compliant (maintained across all substitutes)
• Moisture Sensitivity Level: 1 (Unlimited) (maintained across all substitutes)

Secondary Variation Parameter:

• Length: Tolerance range 0.430" to 0.450" (10.92mm to 11.43mm)

The ELM 1-445, ELM 1-11MM, ELM 3-440, and ELM 3-450 form a substitution group where length variations fall within acceptable mechanical tolerances for T1 3/4 LED standoff applications. All parts maintain identical electrical and material specifications, differing only in nominal length dimensions.

Parameter Comparison

Engineering Selection Recommendations

All four parts—ELM 1-445, ELM 1-11MM, ELM 3-440, and ELM 3-450—are active products with ROHS3 compliance and MSL 1 rating. Selection among these substitutes is determined by:

1. Length Requirement: Choose the part whose nominal length matches the PCB standoff height specification. Length variations range from 0.430" to 0.450" (10.92mm to 11.43mm).

2. Series Compatibility: ELM 1 series (ELM 1-445, ELM 1-11MM) and ELM 3 series (ELM 3-440, ELM 3-450) are functionally equivalent. Series selection does not affect electrical or mechanical performance for T1 3/4 LED mounting.

3. Inventory Availability: ELM 3-440 maintains the highest inventory level (22638 Pcs), followed by ELM 3-450 (8972 Pcs), ELM 1-11MM (1475 Pcs), and ELM 1-445 (759 Pcs).

4. Compliance Status: All parts meet ROHS3 requirements and carry unlimited moisture sensitivity classification, suitable for standard manufacturing and storage environments.

Frequently Asked Questions (FAQ)

Q: Can ELM 1-445 be directly replaced with ELM 3-440?

A: Yes. Both parts maintain identical LED type (T1 3/4), material (Black PVC), color, RoHS compliance, and MSL rating. The primary difference is length: ELM 1-445 is 0.445" (11.30mm) while ELM 3-440 is 0.440" (11.18mm), a 0.005" (0.12mm) variation. Series designation (ELM 1 vs. ELM 3) does not affect functional equivalence.

Q: What is the acceptable length tolerance range for substitution?

A: Substitute parts within this group range from 0.430" to 0.450" (10.92mm to 11.43mm). The maximum variation is 0.020" (0.51mm). Selection must align with the specific PCB standoff height requirement.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. ELM 1-445, ELM 1-11MM, ELM 3-440, and ELM 3-450 are all ROHS3 compliant with MSL 1 (Unlimited) rating.

Q: Does packaging affect substitution eligibility?

A: All parts are supplied in bag packaging. Packaging format does not affect electrical or mechanical substitution criteria.

Q: Which substitute part has the best availability?

A: ELM 3-440 has the highest inventory at 22638 Pcs, followed by ELM 3-450 at 8972 Pcs.

Q: Can these parts be used interchangeably in existing designs?

A: Interchangeability depends on the PCB design tolerance for standoff height. If the design specifies a nominal length of 0.445" (11.30mm), substitute parts must be selected to match or fall within the design's mechanical tolerance window. Length variations of ±0.010" (0.25mm) are typical in PCB standoff applications.
