SL413F Circular Connector Receptacle - Equivalent & Substitute Parts

Part Overview

The SL413F is a 3-position circular connector receptacle with female sockets, manufactured by Switchcraft Inc. as part of the Slim-Line® SL41 series. This component features solder eyelet termination, shielded construction, and is rated for 5A current with applications in audio, industrial, marine, and medical equipment.

The SL413F carries an obsolete product status. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production and field service requirements for systems utilizing this connector.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SL413F is determined by strict equivalence across the following critical parameters:

• Connector Type & Configuration: Receptacle with female sockets, 3-position
• Shell Size & Insert: SL-3F designation
• Termination Method: Solder eyelet(s)
• Fastening & Orientation: Threaded fastening, Orientation B
• Material & Finish Specifications: Copper alloy shell with nickel finish; silver contact finish
• Electrical Rating: 5A current capacity
• Mechanical Features: Cable clamp and strain relief
• Shielding: Shielded construction
• Flammability Compliance: UL94 V-0

The SL413FX qualifies as a direct substitute based on complete alignment with all these parameters. The primary distinction is product status and compliance certification, not functional or mechanical characteristics.

Parameter Comparison

Engineering Selection Recommendations

The SL413FX is the direct substitute for the obsolete SL413F. Both parts are functionally and mechanically identical across all specified parameters. The SL413FX offers the following advantages:

• Active Product Status: SL413FX is currently in active production, ensuring long-term availability and supply chain reliability.
• RoHS3 Compliance: SL413FX meets ROHS3 compliance requirements, whereas the SL413F is non-compliant. This distinction is critical for applications subject to environmental regulations and procurement standards.
• Moisture Sensitivity: SL413FX carries MSL 1 (Unlimited), indicating superior moisture handling characteristics compared to the SL413F.

For new designs and ongoing production, SL413FX is the appropriate selection. For legacy system maintenance where the original SL413F specification must be retained, SL413FX provides full electrical and mechanical compatibility with enhanced compliance posture.

Frequently Asked Questions (FAQ)

Q: Can SL413FX be used as a direct replacement for SL413F in existing assemblies?

A: Yes. SL413FX is mechanically and electrically identical to SL413F across all functional parameters, including connector type, pin count, shell size, termination method, current rating, and shielding. Physical fit and electrical performance are equivalent.

Q: What is the significance of the RoHS compliance difference?

A: SL413F is RoHS non-compliant, while SL413FX is ROHS3 compliant. For applications subject to environmental regulations, procurement policies, or customer requirements mandating RoHS compliance, SL413FX is the required selection. For legacy systems without such requirements, both parts are functionally interchangeable.

Q: Does packaging differ between SL413F and SL413FX?

A: SL413F packaging is listed as unspecified, while SL413FX is supplied in bulk packaging. Verify packaging requirements with your procurement specification before ordering.

Q: Are there any electrical or mechanical performance differences?

A: No. Both parts share identical electrical ratings (5A), mechanical specifications (shell size SL-3F, threaded fastening, Orientation B), material composition (copper alloy shell, nickel finish, silver contact finish), and features (cable clamp, strain relief, shielding, UL94 V-0 flammability rating).

Q: Why is SL413F marked as obsolete?

A: SL413F carries obsolete status, indicating it is no longer in active production. SL413FX represents the current production equivalent and should be specified for all new designs and ongoing procurement.
