SLM-400 LED Standoff Equivalent & Substitute Parts

Part Overview

The SLM-400 is a T1/T1 3/4 LED standoff manufactured by Bivar Inc., designed for vertical mounting applications. This component is constructed from black nylon material with a 0.400" (10.16mm) length specification. The part maintains Active product status and is RoHS3 compliant, making it suitable for current electronic assembly requirements. Equivalent substitute parts are identified based on matching electrical and mechanical parameters, including LED form factor, material composition, color specification, and dimensional tolerances.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SLM-400 are identified through parametric equivalence based on the following criteria:

Primary Matching Parameters:

• LED form factor (T1, T1 3/4) compatibility
• Material composition (Nylon)
• Color specification (Black)
• RoHS3 compliance status
• Active product status

Secondary Consideration:

• Length tolerance within acceptable mechanical fit range for typical PCB mounting applications

The identified substitutes (705820100 and 705820105) from Würth Elektronik maintain identical LED form factor, material, and color specifications. Length variations of ±0.013" to ±0.050" from the nominal 0.400" specification fall within standard mechanical tolerances for LED standoff applications where vertical clearance requirements permit dimensional variation.

Parameter Comparison

Engineering Selection Recommendations

705820100 (Würth Elektronik) is a parametric equivalent with 0.006" (0.16mm) shorter length compared to the SLM-400. This part maintains identical LED form factor, nylon material, and black color specification. RoHS3 compliance and Active product status confirm regulatory alignment and supply continuity. The Nylon 66 material specification with UL94 V-2 rating provides equivalent mechanical and thermal performance.

705820105 (Würth Elektronik) is a parametric equivalent with 0.013" (0.34mm) longer length compared to the SLM-400. This part maintains identical LED form factor, nylon material, and black color specification. RoHS3 compliance and Active product status confirm regulatory alignment and supply continuity. The Nylon 66 material specification with UL94 V-2 rating provides equivalent mechanical and thermal performance.

Both substitutes are suitable for applications where the specified length tolerance accommodates the dimensional variation. Selection between 705820100 and 705820105 depends on PCB clearance requirements and mechanical fit specifications for the target assembly.

Frequently Asked Questions (FAQ)

Q: What determines if a part can substitute for the SLM-400?

A: Substitution eligibility is based on matching LED form factor (T1, T1 3/4), material (Nylon), color (Black), and RoHS3 compliance status. Length variation within standard mechanical tolerances is acceptable where assembly design permits.

Q: Are the Würth Elektronik parts (705820100 and 705820105) interchangeable with the SLM-400?

A: Both parts are parametric equivalents with matching LED form factor, material, and color. Length differences of 0.006" and 0.013" respectively require verification against specific PCB clearance and mounting requirements for your application.

Q: What is the difference between 705820100 and 705820105?

A: Both are Würth Elektronik T1/T1 3/4 black nylon LED standoffs with identical material and compliance specifications. The primary difference is length: 705820100 measures 0.394" (10.00mm) while 705820105 measures 0.413" (10.50mm).

Q: Do all substitute parts have the same RoHS compliance?

A: Yes. The SLM-400 and both substitute parts (705820100 and 705820105) are RoHS3 compliant, ensuring regulatory alignment for restricted substance requirements.

Q: What packaging format is used for these parts?

A: All parts are supplied in Bag packaging format, suitable for standard component handling and assembly processes.

Q: Are there inventory considerations when selecting a substitute?

A: Current inventory levels are: SLM-400 (1094 pcs), 705820100 (6138 pcs), and 705820105 (2331 pcs). Availability should be confirmed with your supplier for production requirements.
