ELM 3-14MM LED Standoff Equivalent & Substitute Parts

Part Overview

The ELM 3-14MM is a T1 3/4 LED standoff manufactured by Bivar Inc., designed for vertical mounting applications with a 0.550" (13.97mm) length. This component is constructed from black PVC material and is currently in active production status. The part is ROHS3 compliant with MSL 1 rating, indicating unlimited moisture sensitivity protection.

Identification of equivalent and substitute parts is necessary to support supply chain continuity, manage inventory optimization, and provide design flexibility when the primary part number becomes unavailable or when alternative sourcing is required.

Substitute Part Grouping Explanation

Substitution eligibility for the ELM 3-14MM is determined by the following critical parameters:

Primary Substitution Criteria:

• LED Type: T1 3/4 form factor
• Material: Black PVC construction
• Mounting Style: Vertical orientation
• Color: Black
• RoHS Compliance: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Dimensional Tolerance: The length parameter allows for minor dimensional variation within acceptable mechanical tolerances. The ELM 3-14MM operates at 0.550" (13.97mm), and substitute parts with lengths within the standard tolerance range of this product category are considered functionally equivalent.

The ELM 1-545 meets all primary substitution criteria with a length of 0.545" (13.84mm), representing a dimensional difference of 0.005" (0.13mm), which falls within acceptable mechanical tolerances for LED standoff applications.

Parameter Comparison

Engineering Selection Recommendations

Both the ELM 3-14MM and ELM 1-545 are active production parts manufactured by Bivar Inc. with identical RoHS3 compliance and MSL 1 ratings. Both components are suitable for applications requiring T1 3/4 LED standoffs with vertical mounting orientation in black PVC construction.

The ELM 1-545 is available in significantly higher inventory (20,121 pieces) compared to the ELM 3-14MM (759 pieces), making it the preferred selection for high-volume production requirements or extended supply chain planning.

The dimensional difference of 0.005" (0.13mm) between the two parts is within standard mechanical tolerances for LED standoff applications and does not affect functional performance or electrical characteristics.

Frequently Asked Questions (FAQ)

Q: What determines if ELM 1-545 can substitute for ELM 3-14MM?

A: Substitution is valid when the following parameters match: LED type (T1 3/4), material (black PVC), mounting style (vertical), color (black), RoHS compliance (ROHS3), and MSL rating (1). The ELM 1-545 meets all these criteria.

Q: Is the 0.005" length difference between ELM 3-14MM and ELM 1-545 significant?

A: No. This dimensional difference of 0.13mm falls within standard mechanical tolerances for LED standoff components and does not impact functional performance or mechanical fit in standard applications.

Q: Are both parts currently available for production use?

A: Yes. Both ELM 3-14MM and ELM 1-545 are active production parts with current inventory in stock.

Q: Do both parts meet the same compliance requirements?

A: Yes. Both parts are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating, meeting identical environmental and regulatory standards.

Q: What is the primary advantage of selecting ELM 1-545 over ELM 3-14MM?

A: The ELM 1-545 offers significantly higher inventory availability (20,121 pieces versus 759 pieces), providing better supply chain security for production planning and high-volume applications.

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

A: Yes. The parts are mechanically and functionally equivalent within standard design tolerances for LED standoff applications.
