SLM-270 Equivalent & Substitute Parts

Part Overview

The SLM-270 is an LED standoff manufactured by Bivar Inc., designed for vertical mounting applications with T1 and T1 3/4 LED form factors. This component is classified as an active product with full RoHS3 compliance and unlimited moisture sensitivity rating (MSL 1). LED standoffs serve as mechanical and electrical positioning elements in circuit assemblies, requiring substitute parts that maintain dimensional, material, and compliance specifications to ensure proper fit and performance in target applications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SLM-270 are identified based on the following critical parameters that determine functional and mechanical compatibility:

Primary Substitution Criteria:

• LED form factor compatibility (T1, T1 3/4)
• Material composition (Nylon)
• Color specification (Black)
• RoHS3 compliance status
• Length tolerance within acceptable mechanical assembly limits
• Packaging format (Bag)

The substitute part 705820070 from Würth Elektronik meets these criteria with a length specification of 0.276" (7.00mm), representing a 0.006" (0.14mm) dimensional variance from the main part. This variance falls within typical mechanical tolerance ranges for LED standoff applications where vertical positioning allows minor length adjustments through standard assembly practices.

Parameter Comparison

Engineering Selection Recommendations

SLM-270 (Bivar Inc.): Select this part for applications requiring the original specification with 0.270" (6.86mm) length and explicit MSL 1 rating documentation. This part maintains active product status with established supply chain availability of 746 units in stock.

705820070 (Würth Elektronik): This substitute part is suitable for applications where the 0.276" (7.00mm) length specification is mechanically acceptable within assembly tolerances. The part is manufactured from Nylon 66 with UL94 V-2 flame rating, providing enhanced material specification. Both parts maintain ROHS3 compliance and active product status. The substitute offers higher inventory availability at 5553 units in stock and includes REACH Unaffected status documentation.

Selection between these parts should be based on:

• Specific mechanical length requirements of the target assembly
• Inventory availability and lead time requirements
• Material specification preferences (standard Nylon vs. Nylon 66 with flame rating)
• Supply chain continuity and manufacturer preference

Frequently Asked Questions (FAQ)

Q: What is the primary difference between SLM-270 and 705820070?

A: The primary difference is the length specification. SLM-270 measures 0.270" (6.86mm), while 705820070 measures 0.276" (7.00mm). Both parts share identical LED form factor (T1, T1 3/4), material type (Nylon), color (Black), and RoHS3 compliance status.

Q: Can 705820070 be used as a direct replacement for SLM-270?

A: The 705820070 is a parametric equivalent based on form factor, material, and compliance specifications. The 0.006" (0.14mm) length difference must be evaluated against the specific mechanical requirements of the target assembly. Applications with rigid height constraints may require the original SLM-270 specification.

Q: Are both parts RoHS3 compliant?

A: Yes, both SLM-270 and 705820070 are ROHS3 compliant, meeting current environmental and hazardous substance restrictions for electronic components.

Q: What does the MSL 1 rating on SLM-270 indicate?

A: MSL 1 (Moisture Sensitivity Level 1) indicates unlimited shelf life with no special moisture control requirements during storage or handling. The 705820070 lists MSL as Not Applicable, indicating this parameter is not specified by the manufacturer for this component type.

Q: Which part has better availability?

A: The 705820070 from Würth Elektronik currently has higher inventory availability at 5553 units compared to 746 units for the SLM-270. Availability should be confirmed with current supplier inventory at time of procurement.

Q: Are both parts suitable for the same LED form factors?

A: Yes, both parts accommodate T1 and T1 3/4 LED form factors, ensuring mechanical compatibility with standard LED component packages.

Q: What is the significance of the Nylon 66 material specification in 705820070?

A: Nylon 66 is a specific polyamide formulation with enhanced thermal and mechanical properties compared to standard Nylon. The UL94 V-2 flame rating indicates compliance with flammability standards for electrical components. This specification may be relevant for applications with elevated temperature or flame-resistance requirements.
