SLM-670 LED Standoff Equivalent & Substitute Parts

Part Overview

The SLM-670 is a T1/T1 3/4 LED standoff manufactured by Bivar Inc., constructed from black nylon with a height of 0.670" (17.02mm). This component is used for vertical mounting and positioning of LED indicators in electronic assemblies. The part is classified as Active status and is ROHS3 compliant. Substitute parts are necessary when primary inventory is depleted, when regional sourcing requirements apply, or when supply chain considerations necessitate alternative component sources that maintain equivalent functional and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

The substitute part 705820170 (Würth Elektronik) is classified as a parametric equivalent based on the following critical parameters that determine mechanical and functional interchangeability:

• LED Type Compatibility: Both parts accommodate T1 and T1 3/4 LED packages
• Material Specification: Both utilize Nylon as the structural material
• Color Match: Both parts are Black
• Length Tolerance: SLM-670 at 0.670" (17.02mm) and 705820170 at 0.669" (17.00mm) represent a 0.02mm dimensional variance, which is within acceptable mechanical tolerance for vertical LED mounting applications
• Mounting Configuration: Both are designed for vertical (T1 SR VERT) LED mounting
• Environmental Compliance: Both parts are ROHS3 compliant, satisfying equivalent environmental and safety standards

Parameter Comparison

Engineering Selection Recommendations

Both the SLM-670 and substitute part 705820170 are Active status components meeting ROHS3 compliance requirements. The SLM-670 carries Moisture Sensitivity Level 1 (unlimited reflow capability), while the 705820170 is classified as Not Applicable for MSL, indicating no moisture-related constraints for either part. Selection between these parts should be based on lead time availability, inventory position, regional supplier preference, or cost considerations, as both parts satisfy equivalent functional and environmental compliance specifications. The negligible 0.02mm length difference does not impact mechanical interchangeability in standard vertical LED mounting applications.

Frequently Asked Questions (FAQ)

Q: Are the SLM-670 and 705820170 mechanically interchangeable?

A: Yes. Both parts accommodate T1 and T1 3/4 LED packages, share identical material composition (Nylon), color (Black), and differ by only 0.02mm in length (0.670" vs 0.669"). This dimensional variation is within acceptable tolerance for vertical standoff applications.

Q: What is the significance of the MSL ratings for these parts?

A: The SLM-670 carries MSL 1 (Unlimited), allowing unlimited reflow cycles without baking requirements. The 705820170 has MSL classified as Not Applicable, indicating no moisture absorption characteristics. Both configurations are suitable for standard assembly processes.

Q: Do both parts meet the same environmental compliance standards?

A: Yes. Both the SLM-670 and 705820170 are ROHS3 compliant and classified as Active products, meeting equivalent environmental and regulatory requirements.

Q: What should determine the choice between these two parts?

A: Since both parts are functionally and mechanically equivalent, selection criteria should be based on supply availability, lead time, cost, regional sourcing preferences, or inventory position. No technical differentiation exists that would favor one part over the other for standard applications.

Q: Are there any material specification differences between these parts?

A: The SLM-670 specifies Nylon material, while the 705820170 specifies Nylon 66 UL94 V-2. Nylon 66 UL94 V-2 represents a flame-rated variant of nylon material. Both are nylon-based and functionally equivalent for LED standoff applications where flame rating is not a primary design requirement. Verification of flame-rating requirements in your specific application is necessary to determine if the UL94 V-2 specification is required.
