SLM-440 Equivalent & Substitute Parts

Part Overview

The SLM-440 is a T1/T1 3/4 LED standoff manufactured by Bivar Inc., designed for vertical mounting applications. This black nylon component measures 0.440" (11.18mm) in length and is classified as an active product with ROHS3 compliance. LED standoffs serve as mechanical and electrical positioning elements in circuit assemblies, requiring substitutes when original inventory is unavailable, when supply chain optimization is necessary, or when alternative sourcing is mandated by procurement specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SLM-440 are qualified based on strict parametric equivalence across the following criteria:

Critical Matching Parameters:

• LED Type: T1 and T1 3/4 compatibility
• Material Composition: Nylon construction
• Color: Black finish
• Length Tolerance: Within acceptable mechanical fit range for vertical mounting applications
• Regulatory Compliance: ROHS3 certification required

Qualifying Substitutes: The parts 705820110 and 705820115, both manufactured by Würth Elektronik, meet the core functional requirements of the SLM-440. Both substitutes maintain T1/T1 3/4 LED compatibility, black nylon construction, and ROHS3 compliance. Length variations (0.433" and 0.453" respectively) represent minor dimensional differences within acceptable tolerances for mechanical standoff applications. Both substitutes are active products with confirmed inventory availability.

Parameter Comparison

Engineering Selection Recommendations

SLM-440 (Primary Part): The SLM-440 remains the specified component for applications requiring the exact 0.440" (11.18mm) length specification. This part maintains active product status with confirmed inventory of 720 pieces. ROHS3 compliance and MSL Level 1 rating support deployment in standard manufacturing environments without moisture-related constraints.

705820110 (Würth Elektronik Substitute): This substitute is suitable for applications where a 0.433" (11.00mm) length is mechanically acceptable. The 0.007" (0.18mm) reduction from the original specification represents a minor dimensional variance. Würth Elektronik's Nylon 66 material with UL94 V-2 rating provides equivalent mechanical performance. ROHS3 compliance and REACH Unaffected status support regulatory requirements. Inventory availability of 5318 pieces provides supply security.

705820115 (Würth Elektronik Substitute): This substitute is suitable for applications where a 0.453" (11.50mm) length is mechanically acceptable. The 0.013" (0.32mm) increase from the original specification represents a minor dimensional variance. Würth Elektronik's Nylon 66 material with UL94 V-2 rating provides equivalent mechanical performance. ROHS3 compliance and REACH Unaffected status support regulatory requirements. Inventory availability of 2240 pieces provides supply security.

Selection between substitutes depends on mechanical tolerance requirements of the specific application. Both substitutes maintain full compliance with the regulatory and material specifications of the original part.

Frequently Asked Questions (FAQ)

Q: What makes 705820110 and 705820115 acceptable substitutes for the SLM-440?

A: Both substitutes maintain identical LED type compatibility (T1/T1 3/4), material composition (nylon), color (black), and regulatory compliance (ROHS3). Length variations of ±0.007" to ±0.013" from the original 0.440" specification fall within acceptable mechanical tolerances for LED standoff applications. Both parts are active products with confirmed inventory.

Q: How do the length differences between SLM-440 and its substitutes affect mechanical fit?

A: The SLM-440 measures 0.440" (11.18mm). The 705820110 measures 0.433" (11.00mm), representing a 0.007" reduction. The 705820115 measures 0.453" (11.50mm), representing a 0.013" increase. These dimensional variations are typical within the LED standoff product category and do not affect functional compatibility with T1/T1 3/4 LED packages. Application-specific mechanical tolerance requirements determine which substitute is appropriate.

Q: Are all three parts packaged identically?

A: Yes. The SLM-440, 705820110, and 705820115 are all supplied in bag packaging, supporting identical receiving, storage, and handling procedures.

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

A: The SLM-440 specifies nylon material. The Würth Elektronik substitutes specify Nylon 66 with UL94 V-2 rating. Nylon 66 is a specific engineering-grade nylon formulation that provides defined mechanical and thermal properties with documented flame-retardant characteristics. Both materials are functionally equivalent for LED standoff applications.

Q: Do the substitutes have different moisture sensitivity requirements?

A: The SLM-440 carries MSL Level 1 (Unlimited), indicating no moisture sensitivity constraints. The Würth Elektronik substitutes list MSL as Not Applicable, indicating equivalent or superior moisture performance. Both conditions support standard manufacturing and storage environments without special moisture control measures.

Q: Are there any regulatory or compliance differences between the three parts?

A: All three parts are ROHS3 compliant and carry EAR99 ECCN classification. The Würth Elektronik substitutes additionally carry REACH Unaffected status. These certifications confirm equivalent regulatory compliance across all three parts for standard industrial applications.

Q: Can 705820110 and 705820115 be used interchangeably with each other?

A: Both parts are Würth Elektronik substitutes for the SLM-440 and share identical LED type, material, and color specifications. The 0.020" (0.50mm) length difference between them (0.433" versus 0.453") determines their interchangeability. Application-specific mechanical tolerance requirements dictate which part is appropriate for a given design.
