SLM-170 LED Standoff Equivalent & Substitute Parts

Part Overview

The SLM-170 is an active LED standoff component manufactured by Bivar Inc., designed for T1 and T1 3/4 LED applications. This vertical mount standoff features black nylon construction with a 0.170" (4.32mm) length specification. The component is ROHS3 compliant and carries Moisture Sensitivity Level 1 (unlimited). Substitute parts are identified when equivalent electrical and mechanical parameters align with the original specification, enabling component procurement flexibility while maintaining functional compatibility in circuit applications.

Substitute Part Grouping Explanation

Substitute part identification for the SLM-170 is based on strict alignment of the following parameters:

Primary Matching Criteria:

• LED Type: T1, T1 3/4 compatibility
• Material: Nylon construction
• Color: Black
• RoHS Compliance: ROHS3 Compliant status

Mechanical Tolerance Consideration: The substitute part 705820045 (Würth Elektronik) specifies a length of 0.177" (4.50mm) compared to the SLM-170 specification of 0.170" (4.32mm). This 0.007" (0.18mm) dimensional variance falls within acceptable mechanical tolerance ranges for LED standoff applications where vertical clearance margins typically accommodate minor height variations.

Regulatory Alignment: Both the main part and substitute maintain ROHS3 compliance and carry identical ECCN classification (EAR99), confirming regulatory equivalence for export and procurement purposes.

Parameter Comparison

Engineering Selection Recommendations

SLM-170 (Bivar Inc.) remains the primary specification when:

• Original design validation has been completed with this specific part number
• Exact 0.170" (4.32mm) length is a critical design constraint
• Existing inventory and supply chain are established

705820045 (Würth Elektronik) is an acceptable substitute when:

• The 0.007" (4.50mm) length increase does not conflict with PCB layout or component clearance requirements
• ROHS3 compliance and EAR99 classification requirements are met
• Supply continuity for the primary part is unavailable
• Both parts maintain active product status with established manufacturing support

Both parts carry identical regulatory classifications and compliance certifications, confirming functional equivalence for standard LED standoff applications.

Frequently Asked Questions (FAQ)

Q: What is the primary difference between SLM-170 and 705820045?

A: The substitute part 705820045 has a length specification of 0.177" (4.50mm) versus the SLM-170 specification of 0.170" (4.32mm). This 0.007" dimensional difference is the only variance between otherwise equivalent components.

Q: Are both parts ROHS3 compliant?

A: Yes. Both SLM-170 and 705820045 carry ROHS3 compliance certification, confirming regulatory equivalence for applications requiring restricted substance compliance.

Q: Can the 0.177" length of part 705820045 be used in place of the 0.170" specification?

A: The dimensional variance of 0.007" (0.18mm) is within standard mechanical tolerances for LED standoff applications. Substitution is valid provided PCB layout and component clearance margins accommodate the increased height. Design verification is required for applications with tight vertical spacing constraints.

Q: What is the packaging format for both parts?

A: Both SLM-170 and 705820045 are supplied in Bag packaging format, suitable for standard component handling and storage procedures.

Q: Are there any differences in moisture sensitivity between these parts?

A: SLM-170 specifies Moisture Sensitivity Level 1 (Unlimited). Part 705820045 lists Moisture Sensitivity as Not Applicable. Both specifications indicate minimal moisture-related handling restrictions for standard storage and assembly environments.

Q: What material specifications apply to the substitute part?

A: Part 705820045 specifies Nylon 66 with UL94 V-2 flame rating, providing enhanced material certification compared to the general nylon specification of SLM-170. This represents an equivalent or superior material specification.

Q: Are export classifications identical for both parts?

A: Yes. Both SLM-170 and 705820045 carry ECCN classification EAR99, confirming identical export control status and regulatory treatment.
