ELM 1-320 LED Standoff: Equivalent & Substitute Parts

Part Overview

The ELM 1-320 is a T1 3/4 LED standoff manufactured by Bivar Inc., designed for vertical mounting applications. This component features a black PVC construction with a 0.320" (8.13mm) length specification. 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 flexibility necessitate alternative components that maintain functional and mechanical compatibility within the ELM series standoff family.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ELM 1-320 is determined by the following critical parameters:

Mandatory Matching Criteria:

• LED Type: T1 3/4 (physical form factor compatibility)
• Material: Black PVC (mechanical and environmental properties)
• Mounting Style: Vertical (application orientation)
• Manufacturer: Bivar Inc. (series consistency)
• RoHS Status: ROHS3 Compliant (regulatory requirement)
• Moisture Sensitivity Level: 1 (Unlimited) (storage and handling compatibility)

Allowable Variation:

• Length: Tolerance within mechanical design constraints of the application

The ELM 3-335 qualifies as a parametric equivalent because it maintains all mandatory matching criteria while varying only in length specification (0.335" versus 0.320"). This length difference of 0.015" (0.38mm) represents a dimensional variation within the same product family and material composition.

Engineering Selection Recommendations

Primary Selection: ELM 1-320 Use the ELM 1-320 when the 0.320" (8.13mm) length specification is required by the mechanical design. This part is Active and maintains full RoHS3 compliance with unlimited moisture sensitivity rating.

Alternative Selection: ELM 3-335 The ELM 3-335 serves as a substitute when the 0.335" (8.51mm) length variation is mechanically acceptable within the application design envelope. Both parts share identical material composition, LED type, mounting orientation, and regulatory compliance status. The ELM 3-335 carries significantly higher inventory availability (14,653 pcs versus 675 pcs), making it suitable for applications where the additional 0.015" length does not create mechanical interference or functional constraints.

Both parts maintain Active product status and ROHS3 compliance, ensuring continued manufacturability and regulatory alignment.

Frequently Asked Questions (FAQ)

Q: Can the ELM 3-335 be used in place of the ELM 1-320?

A: The ELM 3-335 is a parametric equivalent substitute provided the mechanical design accommodates the 0.335" length. The additional 0.015" (0.38mm) must not create interference with adjacent components or violate PCB layout constraints. All other functional and material properties are identical.

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

A: The length difference of 0.015" (0.38mm) represents the primary dimensional variation between these two standoff models. This variation must be evaluated against the specific application's mechanical clearance requirements and mounting surface geometry.

Q: Are both parts RoHS3 compliant?

A: Yes. Both the ELM 1-320 and ELM 3-335 are RoHS3 compliant and carry Moisture Sensitivity Level 1 (Unlimited), indicating no special storage or handling requirements.

Q: Why would I choose the ELM 3-335 over the ELM 1-320?

A: The ELM 3-335 should be selected when inventory availability is a priority and the mechanical design permits the 0.335" length specification. The ELM 3-335 maintains 14,653 units in stock compared to 675 units for the ELM 1-320, reducing lead time risk.

Q: Are these parts from the same manufacturer?

A: Yes. Both parts are manufactured by Bivar Inc. and belong to the same ELM series standoff family, ensuring design consistency and material compatibility.

Q: What packaging format is used for both parts?

A: Both the ELM 1-320 and ELM 3-335 are supplied in Bag packaging, maintaining consistent handling and storage protocols.
