SLM-250 LED Standoff Equivalent & Substitute Parts

Part Overview

The SLM-250 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 0.250" (6.35mm) 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 interchangeability in production and maintenance applications.

Substitute Part Grouping Explanation

Substitute parts for the SLM-250 are qualified based on the following critical parameters:

LED Type Compatibility: Both the main part and substitute must support T1 and T1 3/4 LED form factors.

Material Specification: Black nylon construction is required for mechanical and thermal consistency.

Mechanical Dimensions: Length tolerance is evaluated within acceptable manufacturing variance. The SLM-250 specifies 0.250" (6.35mm); substitute parts with 0.256" (6.50mm) length fall within acceptable mechanical tolerance for vertical standoff applications.

Regulatory Compliance: ROHS3 compliance is mandatory. ECCN classification EAR99 ensures export control consistency.

Packaging Format: Bag packaging maintains handling and inventory compatibility.

The substitute part 705820065 (Würth Elektronik) meets all substitution criteria through alignment on LED type, material, color, regulatory status, and dimensional tolerance.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection: SLM-250 (Bivar Inc.) is the specified component and should be used when available. Active product status and full inventory availability support standard procurement.

Substitute Selection: 705820065 (Würth Elektronik) is qualified as a direct substitute when SLM-250 availability is constrained. Both components carry Active product status, ensuring continued manufacturing support and supply chain stability. ROHS3 compliance and EAR99 classification are identical, eliminating regulatory substitution barriers. The 0.006" (0.15mm) length differential between parts is within acceptable mechanical tolerance for vertical LED standoff applications and does not affect functional performance in T1 and T1 3/4 LED mounting configurations.

Frequently Asked Questions (FAQ)

Q: Can 705820065 be used as a direct replacement for SLM-250 in production?

A: Yes. Both parts support T1 and T1 3/4 LED types, feature black nylon construction, carry ROHS3 compliance, and are packaged in bags. The 0.006" length difference is within acceptable tolerance for vertical standoff applications.

Q: What is the significance of the length difference between SLM-250 (0.250") and 705820065 (0.256")?

A: The 0.006" (0.15mm) difference represents standard manufacturing tolerance in nylon standoff production. This variance does not affect LED seating, electrical performance, or mechanical function in vertical mount configurations.

Q: Are there any regulatory differences between these parts?

A: No. Both parts are ROHS3 compliant, classified as EAR99 for export control, and carry identical regulatory status. Substitution does not introduce compliance risk.

Q: Does the Würth Elektronik part include UL94 V-2 rating while the Bivar part does not specify this?

A: The Würth Elektronik 705820065 explicitly lists UL94 V-2 flame rating in its detailed description. This represents an additional material certification that does not conflict with SLM-250 specifications and may provide enhanced documentation for applications requiring flame-rated materials.

Q: What inventory considerations apply to these substitutes?

A: SLM-250 maintains 613 pieces in stock. 705820065 maintains 4,385 pieces in stock. When SLM-250 availability is limited, the higher inventory level of 705820065 may support extended production schedules.
