SLM-240 LED Standoff Equivalent & Substitute Parts

Part Overview

The SLM-240 is an active LED standoff manufactured by Bivar Inc., designed for T1 and T1 3/4 LED applications. This component functions as a mechanical and electrical support structure for vertical LED mounting, featuring black nylon construction with a 0.240" (6.10mm) length specification. The part maintains ROHS3 compliance and MSL Level 1 rating, indicating suitability for standard storage and handling conditions. Substitute parts are identified when equivalent functional performance can be achieved through components meeting the same electrical and mechanical parameter requirements while maintaining active product status and compliance certifications.

Key Parameters

Parameter	Value	Specification Basis
LED Type Compatibility	T1, T1 3/4	Physical form factor requirement
Material Composition	Nylon	Mechanical and thermal properties
Color	Black	Visual and optical specification
Length Tolerance	0.240" ± tolerance (6.10mm)	Mechanical fit and assembly clearance
Product Status	Active	Availability and manufacturer support
RoHS Compliance	ROHS3 Compliant	Environmental and regulatory requirement
Moisture Sensitivity Level	MSL 1 (Unlimited)	Storage and handling classification

Substitute Part Grouping Explanation

Substitution eligibility for the SLM-240 is determined by strict alignment with the following parameters:

Primary Compatibility Criteria:

LED form factor: T1 or T1 3/4 compatibility required
Material: Nylon construction mandatory
Color: Black specification required
Length: Mechanical dimension within functional tolerance range (0.236" to 0.240" represents acceptable variation for vertical standoff applications)
Product Status: Active status required for current availability
RoHS Compliance: ROHS3 Compliant status required

The substitute part 705820060 (Würth Elektronik) satisfies all primary criteria. The length specification of 0.236" (6.00mm) represents a 0.004" (0.10mm) dimensional variance from the main part, which falls within acceptable mechanical tolerance for LED standoff applications where vertical spacing is the functional requirement.

Parameter Comparison

Parameter	SLM-240 (Bivar Inc.)	705820060 (Würth Elektronik)	Compatibility Status
LED Type	T1, T1 3/4	T1, T1 3/4	Equivalent
Material	Nylon	Nylon 66 UL94 V-2	Equivalent
Color	Black	Black	Equivalent
Length	0.240" (6.10mm)	0.236" (6.00mm)	Within tolerance
Product Status	Active	Active	Equivalent
RoHS Compliance	ROHS3 Compliant	ROHS3 Compliant	Equivalent
Packaging	Bag	Bag	Equivalent

Engineering Selection Recommendations

SLM-240 (Bivar Inc.): Select this part for applications requiring the original specification with 0.240" (6.10mm) length. Active product status ensures current manufacturer support and consistent supply chain availability. ROHS3 compliance and MSL Level 1 rating confirm suitability for standard industrial and commercial applications.

705820060 (Würth Elektronik): This substitute part provides functional equivalence with a 0.004" (0.10mm) length reduction. The nylon 66 material with UL94 V-2 rating indicates enhanced flame resistance properties. Active product status and ROHS3 compliance maintain regulatory alignment. The 0.236" dimension accommodates applications where slightly reduced standoff height is acceptable within circuit board design tolerances.

Selection between these parts depends on specific assembly requirements regarding vertical spacing and flame resistance specifications. Both parts maintain active status and full compliance certifications.

Frequently Asked Questions (FAQ)

Q: What determines if a part can substitute for the SLM-240?

A: Substitute parts must match the following parameters: T1 or T1 3/4 LED compatibility, black nylon material, active product status, and ROHS3 compliance. Length specifications must fall within the functional tolerance range for vertical LED standoff applications (0.236" to 0.240" represents acceptable variation).

Q: Is the 0.004" length difference between SLM-240 and 705820060 functionally significant?

A: The 0.004" (0.10mm) difference represents a 1.7% dimensional variance. For vertical LED standoff applications, this variance falls within standard mechanical tolerances and does not affect functional performance in typical circuit board assembly designs. Verification against specific board layout requirements is necessary for critical spacing applications.

Q: Are both parts available in the same packaging format?

A: Yes. Both SLM-240 and 705820060 are supplied in bag packaging, enabling equivalent handling and storage procedures.

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

A: UL94 V-2 indicates flame resistance classification for the nylon 66 material. This specification provides enhanced fire safety properties compared to standard nylon. Applications requiring specific flame resistance certifications should reference this rating.

Q: Do both parts have the same moisture sensitivity requirements?

A: SLM-240 carries MSL Level 1 (Unlimited) rating. The Würth Elektronik part lists MSL as Not Applicable, indicating no moisture sensitivity restrictions. Both parts accommodate standard storage and handling without special moisture control measures.

Q: Can these parts be used interchangeably in existing designs?

A: Functional interchangeability is supported by equivalent LED type compatibility, material composition, color specification, and compliance certifications. The 0.004" length variance requires verification against specific circuit board assembly drawings to confirm acceptable vertical spacing.
