SLM-450 Equivalent & Substitute Parts

Part Overview

The SLM-450 is a T1/T1 3/4 LED standoff manufactured by Bivar Inc., constructed from black nylon with a 0.450" (11.43mm) length. This component functions as a mechanical support and alignment structure for LED assemblies in vertical mounting configurations. The part maintains Active product status and is RoHS3 compliant with MSL 1 rating, indicating unlimited moisture tolerance.

Substitute parts become necessary when primary inventory is unavailable, when supply chain disruptions occur, or when design flexibility permits dimensional tolerance within specified parameters. Alternative sources from qualified manufacturers ensure production continuity while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SLM-450 is determined by strict adherence to the following parameters:

Critical Matching Parameters:

• LED Type: T1 and T1 3/4 compatibility required
• Material: Nylon construction mandatory
• Color: Black finish required
• Length: Tolerance range 0.433" to 0.472" (11.00mm to 12.00mm)

Compliance Parameters:

• RoHS3 compliance required
• ECCN EAR99 classification maintained
• Active product status

The three Würth Elektronik parts (705820110, 705820115, 705820120) qualify as parametric equivalents because they satisfy all critical matching parameters while maintaining regulatory compliance. Length variations within the specified tolerance range accommodate standard mechanical assembly tolerances in LED standoff applications.

Parameter Comparison

Engineering Selection Recommendations

All three Würth Elektronik substitute parts maintain Active product status and full RoHS3 compliance, ensuring regulatory alignment with the SLM-450. Selection among the three alternatives depends on mechanical assembly requirements:

705820110 (0.433" / 11.00mm): Shortest available option, suitable for applications requiring minimal standoff height.

705820115 (0.453" / 11.50mm): Closest dimensional match to the SLM-450 at 0.450" (11.43mm), providing maximum compatibility with existing mechanical designs.

705820120 (0.472" / 12.00mm): Longest available option, appropriate for applications requiring increased standoff height or additional clearance.

All substitute parts utilize Nylon 66 material with UL94 V-2 flame rating, maintaining mechanical and thermal properties consistent with the original SLM-450 specification. Inventory availability across all three alternatives ensures supply chain flexibility.

Frequently Asked Questions (FAQ)

Q: Can the SLM-450 be directly replaced with any of the Würth Elektronik parts?

A: Yes, all three Würth Elektronik parts (705820110, 705820115, 705820120) are parametric equivalents. Selection depends on the specific length requirement for your mechanical assembly. The 705820115 provides the closest dimensional match at 0.453" (11.50mm) versus the original 0.450" (11.43mm).

Q: What is the acceptable length tolerance range for substitution?

A: The substitute parts span from 0.433" (11.00mm) to 0.472" (12.00mm). This range accommodates standard mechanical assembly tolerances in LED standoff applications. Verify your specific design requirements before selection.

Q: Are all substitute parts RoHS3 compliant?

A: Yes, all three Würth Elektronik substitute parts maintain full RoHS3 compliance, matching the regulatory status of the SLM-450.

Q: Do the substitute parts use the same material as the SLM-450?

A: The SLM-450 uses nylon material, while the Würth Elektronik substitutes specify Nylon 66 with UL94 V-2 flame rating. Nylon 66 is a standard engineering-grade nylon variant that maintains mechanical and thermal properties suitable for LED standoff applications.

Q: What is the difference between the three Würth Elektronik options?

A: The three parts differ only in length: 705820110 at 0.433" (11.00mm), 705820115 at 0.453" (11.50mm), and 705820120 at 0.472" (12.00mm). All other parameters including LED type, material, color, compliance status, and packaging are identical.

Q: Are there any moisture sensitivity concerns with these substitutes?

A: The SLM-450 carries MSL 1 rating (unlimited moisture tolerance). The Würth Elektronik substitutes list MSL as Not Applicable, indicating they are not moisture-sensitive components. Both approaches are suitable for standard industrial and commercial applications.

Q: Can I use these parts interchangeably in existing designs?

A: Interchangeability depends on mechanical tolerance in your specific design. The length variation of ±0.022" (±0.57mm) from the nominal SLM-450 dimension may be acceptable depending on your assembly clearances and mechanical constraints. Verify dimensional compatibility with your mechanical design before implementation.
