SLM-330 LED Standoff Equivalent & Substitute Parts

Part Overview

The SLM-330 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 0.330" (8.38mm) length specification. The part maintains Active product status and is ROHS3 compliant with MSL Level 1 rating, indicating unlimited moisture sensitivity tolerance.

Substitute parts are identified when equivalent functional performance can be achieved through alternative manufacturers while maintaining compatibility with the specified LED form factor, material composition, and mechanical mounting requirements.

Key Parameters

Parameter	Value	Significance for Substitution
LED Form Factor	T1, T1 3/4	Determines physical compatibility with LED component
Material	Nylon	Defines mechanical and thermal properties
Color	Black	Optical and aesthetic specification
Length	0.330" (8.38mm)	Critical for mounting height and PCB clearance
RoHS Status	ROHS3 Compliant	Regulatory compliance requirement
Packaging	Bag	Handling and storage specification

Substitute Part Grouping Explanation

Substitute parts for the SLM-330 are qualified based on the following criteria:

Primary Compatibility Parameters:

LED form factor match (T1, T1 3/4)
Material composition (Nylon)
Color specification (Black)
RoHS3 compliance status
Packaging format (Bag)

Length Tolerance Consideration: Substitute parts are grouped by length deviation from the primary specification. The SLM-330 specifies 0.330" (8.38mm). Würth Elektronik part 705820085 provides 0.335" (8.50mm), representing a +0.005" (0.12mm) variance. Würth Elektronik part 705820080 provides 0.315" (8.00mm), representing a -0.015" (0.38mm) variance.

Both substitute parts maintain identical LED form factor, material, color, and regulatory compliance as the primary part. Substitution validity depends on application-specific mounting height requirements and PCB clearance specifications.

Engineering Selection Recommendations

SLM-330 (Bivar Inc.): Select this part when the exact 0.330" (8.38mm) length specification is required for PCB mounting height and component clearance. This part maintains Active status with established supply availability of 1015 pieces. ROHS3 compliance and MSL Level 1 rating support unrestricted moisture exposure applications.

705820085 (Würth Elektronik): This substitute provides a +0.005" (8.50mm) length variant. Select when the application tolerates increased standoff height. This part offers higher inventory availability (1971 pieces) and maintains identical LED form factor, material, color, and regulatory compliance. Nylon 66 material specification provides equivalent mechanical properties to the primary part.

705820080 (Würth Elektronik): This substitute provides a -0.015" (8.00mm) length variant. Select when reduced standoff height is acceptable for the application. This part offers the highest inventory availability (17403 pieces) and maintains identical LED form factor, material, color, and regulatory compliance. Nylon 66 material specification provides equivalent mechanical properties to the primary part.

All three parts maintain ROHS3 compliance and Active product status, supporting regulatory requirements for current production environments.

Frequently Asked Questions (FAQ)

Q: What determines if a part can substitute for the SLM-330?

A: Substitute parts must match the LED form factor (T1, T1 3/4), material composition (Nylon), color (Black), and RoHS3 compliance status. Length variance is application-dependent and must be evaluated against specific PCB mounting height and component clearance requirements.

Q: How significant is the length difference between substitute parts?

A: The SLM-330 specifies 0.330" (8.38mm). Part 705820085 varies by +0.005" (0.12mm), and part 705820080 varies by -0.015" (0.38mm). These differences affect PCB-to-component clearance and must be validated against application-specific mechanical constraints.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. The SLM-330, 705820085, and 705820080 all maintain ROHS3 compliance status, supporting regulatory requirements for restricted substance elimination.

Q: What is the difference between Nylon and Nylon 66?

A: Both materials are nylon-based polymers suitable for LED standoff applications. Nylon 66 is a specific polyamide formulation. The substitute parts specify Nylon 66, while the primary part specifies Nylon. Both provide equivalent mechanical and thermal properties for this application category.

Q: Which part offers the best inventory availability?

A: Part 705820080 (Würth Elektronik) provides the highest inventory availability at 17403 pieces, compared to 1971 pieces for 705820085 and 1015 pieces for the SLM-330.

Q: Can these parts be used interchangeably in all applications?

A: Interchangeability depends on application-specific mounting height tolerance. The length variance between parts (0.315" to 0.335") must be evaluated against PCB clearance, component spacing, and mechanical mounting requirements specific to each application.

Q: What is the MSL rating significance?

A: The SLM-330 carries MSL Level 1, indicating unlimited moisture sensitivity tolerance. Würth Elektronik substitutes list MSL as Not Applicable, indicating these parts do not require moisture sensitivity classification for this product category.
