Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SL405F is determined by strict equivalence across the following critical parameters:

• Connector type (Plug, Female Sockets)
• Number of positions (5)
• Shell size designation (SL-5F)
• Termination method (Solder Eyelet)
• Fastening mechanism (Threaded)
• Orientation (D)
• Shell material and finish (Copper Alloy, Nickel)
• Contact finish (Silver)
• Shielding configuration (Shielded)
• Current rating (5A)
• Cable opening dimension (0.280" / 7.10mm)
• Integrated features (Cable Clamp, Coupling Nut, Strain Relief)

The SL405FX meets all these criteria and qualifies as a direct substitute. The primary distinction between the main part and its substitute is product status and compliance certification.

Parameter Comparison

Engineering Selection Recommendations

The SL405FX is the direct substitute for the SL405F. Both connectors are electrically and mechanically identical across all functional parameters. The SL405FX is preferred for new designs and ongoing production due to its active product status and ROHS3 compliance certification. The SL405F, classified as obsolete, presents supply chain risk and does not meet current RoHS3 regulatory requirements.

For applications currently specified with SL405F, transition to SL405FX provides equivalent performance while ensuring regulatory compliance and supply availability. No design modifications are required for this substitution.

Frequently Asked Questions (FAQ)

Q: Are SL405F and SL405FX mechanically interchangeable? A: Yes. Both connectors share identical shell size (SL-5F), position count (5), termination method (solder eyelet), fastening type (threaded), and all mechanical dimensions including cable opening (0.280" / 7.10mm).

Q: Are SL405F and SL405FX electrically interchangeable? A: Yes. Both connectors have identical current rating (5A), contact material (copper alloy), contact finish (silver), and shielding configuration. They are electrically equivalent.

Q: What is the primary reason to substitute SL405F with SL405FX? A: The SL405F is obsolete, creating supply chain discontinuity. The SL405FX is an active product with identical electrical and mechanical specifications, ensuring long-term availability and regulatory compliance (ROHS3).

Q: Does the packaging difference affect compatibility? A: No. Packaging format (bulk for SL405FX versus unspecified for SL405F) does not affect connector form, fit, or function. It reflects only the distribution method.

Q: Are there any compliance differences between these connectors? A: The SL405FX meets ROHS3 compliance, while the SL405F does not. Both maintain UL94 V-0 flammability rating and REACH unaffected status. For applications subject to RoHS regulations, SL405FX is required.
