Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SL174F is determined by strict equivalence across the following critical parameters:

• Connector type and gender (Receptacle, Female Sockets)
• Position count (4 positions)
• Shell size designation (SL-4F)
• Mounting configuration (Panel Mount, Bulkhead - Front Side Nut)
• Termination method (Solder Eyelet(s))
• Fastening mechanism (Threaded)
• Orientation (C)
• Shell and contact materials (Zinc Alloy shell, Copper Alloy contacts)
• Surface finishes (Nickel shell, Silver contact mating)
• Current rating (5A)
• Shielding classification (Unshielded)
• Flammability compliance (UL94 V-0)

The SL174FX qualifies as a direct substitute based on complete alignment with all specified parameters. The primary distinction is product status and regulatory compliance.

Parameter Comparison

Engineering Selection Recommendations

The SL174FX is the direct equivalent substitute for the obsolete SL174F. Both parts maintain identical mechanical and electrical specifications across all functional parameters. The SL174FX is currently in active production status, ensuring availability for new procurement and system maintenance.

The SL174FX provides improved regulatory compliance through ROHS3 certification, whereas the SL174F is RoHS non-compliant. Both parts maintain equivalent REACH unaffected status and EAR99 export classification. Selection of the SL174FX eliminates obsolescence risk and aligns with current environmental compliance requirements.

Frequently Asked Questions (FAQ)

Q: Can SL174FX be used as a direct replacement for SL174F?

A: Yes. The SL174FX is a direct equivalent substitute. All mechanical dimensions, electrical ratings, termination methods, and mounting configurations are identical. The parts are interchangeable at the circuit board and panel mount level.

Q: What is the primary difference between SL174F and SL174FX?

A: The SL174F is obsolete and RoHS non-compliant. The SL174FX is in active production and ROHS3 compliant. Functionally and mechanically, the parts are equivalent.

Q: Are there any compatibility concerns when substituting SL174FX for SL174F?

A: No compatibility concerns exist. Both connectors share identical shell size (SL-4F), position count (4), mounting configuration (panel mount bulkhead), and termination method (solder eyelet). Existing cable assemblies and mating plugs designed for SL174F will function with SL174FX without modification.

Q: What is the packaging difference between these parts?

A: SL174F packaging is not specified in available documentation. SL174FX is supplied in bulk packaging. Packaging format does not affect functional or mechanical compatibility.

Q: Are both parts suitable for audio, industrial, marine, and medical applications?

A: Yes. Both SL174F and SL174FX are rated for audio, industrial, marine, and medical applications. The UL94 V-0 flammability rating and 5A current capacity support these application categories.
