SLM-280 Equivalent & Substitute Parts

Part Overview

The SLM-280 is an LED standoff manufactured by Bivar Inc., designed for T1 and T1 3/4 LED applications. This component is a vertical mount nylon standoff with a 0.280" (7.11mm) length and black color finish. The part maintains Active product status and is RoHS3 compliant with MSL Level 1 rating, indicating unlimited moisture tolerance. Substitute parts are identified when equivalent electrical and mechanical parameters align with the original specification, enabling direct component replacement in assembly applications.

Key Parameters

Substitute Part Grouping Explanation

Substitute part 705820070 (Würth Elektronik) qualifies as a parametric equivalent based on the following alignment criteria:

Matching Parameters:

• LED Type: T1, T1 3/4 (identical)
• Material: Nylon (identical)
• Color: Black (identical)
• RoHS Status: ROHS3 Compliant (identical)
• Product Status: Active (identical)

Tolerance Consideration:

• Length: 0.276" (7.00mm) versus 0.280" (7.11mm) represents a 0.004" (0.11mm) dimensional variance within typical mechanical tolerance ranges for nylon standoff components

The substitute maintains functional equivalence for LED standoff applications where the specified dimensional tolerance accommodates the 0.11mm length difference.

Parameter Comparison

Engineering Selection Recommendations

Both SLM-280 and 705820070 maintain Active product status with full RoHS3 compliance, ensuring regulatory alignment for current and future applications. The Würth Elektronik part 705820070 specifies UL94 V-2 flame rating for the nylon material, providing documented flammability performance. Selection between these parts should be based on:

• Availability and lead time requirements
• Inventory management and supply chain strategy
• Dimensional tolerance acceptance for the 0.004" length variance
• Supplier qualification and quality system requirements

Both parts are suitable for direct substitution in T1 and T1 3/4 LED standoff applications where the specified mechanical and compliance parameters are required.

Frequently Asked Questions (FAQ)

Q: Can 705820070 directly replace SLM-280 in production?

A: Yes, 705820070 qualifies as a parametric equivalent for T1 and T1 3/4 LED standoff applications. The 0.004" (0.11mm) length difference falls within acceptable mechanical tolerances for nylon standoff components. Verification of dimensional fit within your specific PCB assembly design is required.

Q: What is the significance of the UL94 V-2 rating on the Würth part?

A: UL94 V-2 is a flammability classification for nylon materials indicating flame resistance performance. This specification is provided by Würth Elektronik for material documentation. The SLM-280 specification does not include this detail in the provided data.

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

A: SLM-280 carries MSL Level 1 (Unlimited), indicating no moisture sensitivity restrictions. The Würth part lists MSL as Not Applicable, which is consistent with nylon standoff components that do not require moisture-controlled storage.

Q: Do both parts have identical ECCN and HTSUS classifications?

A: Both parts share ECCN EAR99 classification. HTSUS codes differ (8547.20.0000 for Bivar versus 3926.90.9985 for Würth), reflecting different tariff classifications based on product categorization methodology.

Q: What packaging format is used for both parts?

A: Both SLM-280 and 705820070 are supplied in Bag packaging format suitable for component handling and assembly operations.
