SLM-290 Equivalent & Substitute Parts

Part Overview

The SLM-290 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, and substitute parts may be required due to supply chain constraints, design revisions, or manufacturing discontinuation of original components.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SLM-290 are identified based on strict parametric equivalence within the following criteria:

Primary Matching Parameters:

• LED form factor compatibility (T1, T1 3/4)
• Material composition (Nylon)
• Color specification (Black)
• RoHS3 compliance status
• Mechanical length tolerance within acceptable assembly limits

Tolerance Consideration: Length variation between the main part (0.290" / 7.37mm) and substitute parts is evaluated within standard mechanical tolerances for standoff applications. A substitute with length 0.295" (7.50mm) represents a 0.005" (0.13mm) difference, which falls within typical PCB assembly tolerances for non-critical standoff positioning.

The substitute part 705820075 from Würth Elektronik meets all primary matching parameters and maintains regulatory compliance through ROHS3 certification.

Parameter Comparison

Engineering Selection Recommendations

SLM-290 (Bivar Inc.): Select this part for applications requiring the original specification with 0.290" (7.37mm) standoff height. Product is active with full inventory availability and ROHS3 compliance.

705820075 (Würth Elektronik): This substitute part is suitable for applications where the 0.005" (0.13mm) length increase is acceptable within assembly tolerances. The part features UL94 V-2 flame rating certification in addition to ROHS3 compliance, providing enhanced material specification documentation. Higher inventory availability (2608 pcs vs. 805 pcs) may support supply chain continuity.

Both parts are active products with equivalent regulatory compliance. Selection between them should be based on:

• Specific PCB assembly height requirements
• Preferred supplier relationship
• Inventory availability at time of procurement
• Material certification requirements (UL94 rating)

Frequently Asked Questions (FAQ)

Q: Can 705820075 be used as a direct replacement for SLM-290 in existing designs?

A: The 705820075 is mechanically and electrically compatible with SLM-290 for most applications. The 0.005" (0.13mm) length difference must be evaluated against your specific PCB assembly clearance requirements. If the design has tight vertical spacing constraints, physical validation is necessary before production implementation.

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

A: UL94 V-2 is a flame retardancy classification for polymeric materials. This indicates the Würth Elektronik part has documented flammability performance. The SLM-290 specification does not include this certification detail in the provided data. Both parts are nylon-based and ROHS3 compliant.

Q: Are there any electrical performance differences between these parts?

A: Both parts are passive mechanical standoffs with identical electrical function. No electrical performance variation exists between the two parts.

Q: What is the moisture sensitivity difference between the parts?

A: The SLM-290 specifies MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. The 705820075 lists MSL as Not Applicable, which is consistent with nylon material properties. Both parts have equivalent moisture handling characteristics.

Q: Which part should I select for new designs?

A: For new designs, either part is acceptable based on the parametric equivalence established above. Consider supplier availability, lead time, and any specific material certifications required by your application or customer specifications.
