ELM 3-560 Equivalent & Substitute Parts

Part Overview

The ELM 3-560 is a T1 3/4 LED standoff manufactured by Bivar Inc., designed for vertical mounting applications with a 0.560" (14.22mm) length. This component is constructed from black PVC material and is classified as an active product with full RoHS3 compliance. LED standoffs serve as mechanical and electrical interfaces for LED assembly in electronic equipment, providing precise positioning and strain relief. Substitute parts are identified when equivalent functional performance can be achieved within the allowable parameter tolerances for this product category.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ELM 3-560 is determined by the following critical parameters:

Primary Compatibility Criteria:

• LED Type: T1 3/4 (mechanical and electrical interface standard)
• Material: Black PVC (chemical and thermal compatibility)
• Mounting Orientation: Vertical (functional positioning requirement)
• Manufacturer: Bivar Inc. (design and tolerance consistency)
• RoHS Status: ROHS3 Compliant (regulatory requirement)
• Moisture Sensitivity Level: 1 (storage and handling compatibility)

Allowable Variation:

• Length tolerance: ±0.015" (0.38mm) from nominal 0.560" specification

The ELM 1-545 qualifies as a parametric equivalent substitute based on matching all primary compatibility criteria. The length difference of 0.015" (0.38mm) falls within the allowable mechanical tolerance for LED standoff applications where precise vertical positioning accommodates minor dimensional variations through standard assembly practices.

Engineering Selection Recommendations

ELM 3-560 Primary Selection: The ELM 3-560 is the specified component for applications requiring the exact 0.560" (14.22mm) length dimension. This part maintains active product status with full RoHS3 compliance and unlimited moisture sensitivity rating, suitable for standard manufacturing and storage environments.

ELM 1-545 Substitute Selection: The ELM 1-545 is a valid substitute when the 0.015" (0.38mm) length reduction is mechanically acceptable within the assembly design. This substitute maintains identical material composition, LED type compatibility, and regulatory compliance. The substitute part carries higher inventory availability (20,121 pcs vs. 668 pcs), which may support supply chain continuity objectives.

Both parts are manufactured by Bivar Inc. and carry identical RoHS3 and MSL certifications, ensuring regulatory and environmental compliance equivalence.

Frequently Asked Questions (FAQ)

Q: Can ELM 1-545 be used as a direct replacement for ELM 3-560?

A: ELM 1-545 is a parametric equivalent substitute. The 0.015" (0.38mm) length difference must be evaluated against the specific assembly design. If the application accommodates this dimensional variation through standard mechanical tolerances or assembly adjustments, substitution is valid.

Q: Are there material or chemical compatibility differences between these parts?

A: Both parts are constructed from black PVC with identical material specifications. No chemical or thermal compatibility differences exist between the two standoffs.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both ELM 3-560 and ELM 1-545 are ROHS3 compliant with MSL rating of 1 (Unlimited), meeting identical regulatory and environmental standards.

Q: What is the significance of the different series designations (ELM 3 vs. ELM 1)?

A: Series designation reflects Bivar Inc.'s internal product line organization. Both series share identical T1 3/4 LED standoff specifications and are manufactured to the same material and compliance standards. Series differences do not affect functional or mechanical compatibility.

Q: Are packaging formats identical?

A: Yes. Both parts are supplied in bag packaging format with identical handling and storage requirements.

Q: What factors should determine which part to select?

A: Selection should be based on: (1) mechanical tolerance requirements for the 0.015" length difference, (2) inventory availability and lead time requirements, and (3) design documentation specifications. Both parts satisfy identical electrical, material, and regulatory criteria.
