SLM-320 LED Standoff Equivalent & Substitute Parts

Part Overview

The SLM-320 is a T1/T1 3/4 LED standoff manufactured by Bivar Inc., designed for vertical mounting applications. This component features a black nylon construction with a 0.320" (8.13mm) length and is classified as an active product with ROHS3 compliance. LED standoffs serve as mechanical and electrical positioning elements in circuit assemblies, and equivalent substitutes may be required due to inventory availability, supply chain considerations, or specific application requirements within the defined parameter tolerances.

Substitute Part Grouping Explanation

Substitute parts for the SLM-320 are qualified based on the following critical parameters that determine functional and mechanical compatibility:

Primary Compatibility Criteria:

• LED Type: T1, T1 3/4 (must match)
• Material: Nylon (must match)
• Color: Black (must match)
• Length Tolerance: 0.315" to 0.335" (8.00mm to 8.50mm) — within acceptable mechanical fit range for standard PCB mounting applications
• RoHS Compliance: ROHS3 Compliant (regulatory requirement)
• Packaging: Bag (standard format)

The two qualified substitutes (705820080 and 705820085, both manufactured by Würth Elektronik) meet all primary compatibility criteria. Length variations of ±0.015" (±0.38mm) from the nominal 0.320" specification remain within standard mechanical tolerances for LED standoff applications and do not affect electrical performance or mounting compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts (705820080 and 705820085) are qualified equivalents for the SLM-320 based on the following engineering criteria:

Regulatory Compliance: All three parts maintain ROHS3 compliance and EAR99 export classification, ensuring regulatory compatibility across manufacturing and distribution environments.

Product Status: The SLM-320 and both substitute parts are classified as active products, confirming ongoing manufacturer support and supply availability.

Mechanical Compatibility: The length variations between parts (0.315" to 0.335") fall within standard mechanical tolerances for T1/T1 3/4 LED standoff applications. These dimensional differences do not affect electrical performance, PCB mounting compatibility, or LED positioning accuracy in standard circuit assemblies.

Material Specification: Würth Elektronik substitutes specify Nylon 66 with UL94 V-2 rating, which represents a defined material grade within the nylon family and is functionally equivalent to the Bivar Inc. nylon specification for this application category.

Selection between the three parts should be based on inventory availability, lead time requirements, and specific PCB design tolerances. No technical performance differentiation exists between these parts within the defined parameter set.

Frequently Asked Questions (FAQ)

Q: Can 705820080 and 705820085 be used interchangeably with SLM-320 in the same circuit assembly?

A: Yes. Both Würth Elektronik parts meet all critical compatibility parameters: T1/T1 3/4 LED type, black nylon material, and ROHS3 compliance. Length variations (0.315" and 0.335" versus 0.320") are within standard mechanical tolerances for LED standoff applications and do not affect mounting or electrical function.

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

A: The length differences (±0.015" from nominal) represent standard manufacturing tolerances in the LED standoff category. These variations do not impact PCB mounting height, LED positioning accuracy, or electrical performance in standard applications. Design-specific height constraints should be verified against individual PCB requirements.

Q: Are there any compliance or certification differences between the main part and substitutes?

A: No. All three parts are ROHS3 compliant, carry EAR99 export classification, and maintain active product status. The Würth Elektronik parts include UL94 V-2 material certification, which is a defined specification within nylon material standards and does not create incompatibility.

Q: What packaging format is used for these parts?

A: All three parts are supplied in bag packaging, the standard format for LED standoff components. Bag packaging is suitable for automated assembly processes and manual placement applications.

Q: How should I select between the three available parts?

A: Selection should be based on inventory availability, supplier lead times, and cost considerations. From an engineering standpoint, no technical differentiation exists. Verify that the selected part's length (0.315", 0.320", or 0.335") is compatible with your specific PCB design height requirements.
