Substitute Part Grouping Explanation

The SL172FX qualifies as a direct substitute for the SL172F based on identical electrical and mechanical parameters. Substitution is valid when the following criteria are met:

• Identical connector type: Receptacle, Female Sockets
• Identical number of positions: 2
• Identical shell size and insert designation: SL-2F
• Identical mounting configuration: Panel Mount with Bulkhead Front Side Nut
• Identical termination method: Solder Eyelet(s)
• Identical fastening type: Threaded
• Identical orientation: A
• Identical shell material and finish: Zinc Alloy with Nickel finish
• Identical contact material and finish: Copper Alloy with Silver mating finish
• Identical current rating: 5A
• Identical flammability rating: UL94 V-0
• Identical shielding configuration: Unshielded
• Identical insert material: Thermoplastic
• Identical application scope: Audio, Industrial, Marine, Medical

The primary distinction between SL172F and SL172FX is product status and regulatory compliance. SL172FX is active production and ROHS3 compliant, whereas SL172F is obsolete and RoHS non-compliant.

Parameter Comparison

Engineering Selection Recommendations

The SL172FX is the direct equivalent for the obsolete SL172F. Selection of SL172FX is appropriate for new designs and procurement activities due to active product status and ROHS3 compliance. For legacy systems currently using SL172F, the SL172FX provides identical electrical and mechanical performance with improved regulatory standing.

The transition from SL172F to SL172FX does not require circuit redesign or mechanical modification. Both parts maintain identical connector geometry, pin configuration, current handling capacity, and material specifications. The SL172FX is available in bulk packaging with confirmed inventory of 678 pieces.

Frequently Asked Questions (FAQ)

Q: Can SL172FX directly replace SL172F in existing assemblies?

A: Yes. The SL172FX is mechanically and electrically identical to SL172F. No modifications to PCB layout, panel cutouts, or wiring are required. Both parts use identical solder eyelet termination and panel mount configuration.

Q: What is the primary reason to transition from SL172F to SL172FX?

A: SL172F is obsolete and RoHS non-compliant. SL172FX is active production and ROHS3 compliant, ensuring long-term availability and regulatory alignment for new designs and system updates.

Q: Are there any electrical performance differences between SL172F and SL172FX?

A: No. Both parts maintain identical current rating (5A), contact material (Copper Alloy with Silver finish), and flammability rating (UL94 V-0). Electrical performance is equivalent.

Q: What packaging is available for SL172FX?

A: SL172FX is supplied in bulk packaging with current inventory of 678 pieces.

Q: Are both parts suitable for the same applications?

A: Yes. Both SL172F and SL172FX are specified for Audio, Industrial, Marine, and Medical applications with identical mechanical and environmental specifications.
