Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SL175F is determined by strict equivalence across the following critical parameters:

• Connector type and gender (Receptacle, Female Sockets)
• Position count (5 positions)
• Shell size designation (SL-5F)
• Mounting configuration (Panel Mount, Bulkhead - Front Side Nut)
• Termination method (Solder Eyelet)
• Fastening mechanism (Threaded)
• Orientation (D)
• Material specifications (Zinc Alloy shell, Nickel finish, Silver contact finish, Copper Alloy contacts)
• Current rating (5A)
• Flammability compliance (UL94 V-0)

The SL175FX meets all these criteria and qualifies as a direct substitute. The primary distinction is product status: SL175F is obsolete while SL175FX is active, with improved regulatory compliance.

Parameter Comparison

Engineering Selection Recommendations

The SL175FX is the direct equivalent for the obsolete SL175F. Both components share identical mechanical, electrical, and material specifications across all critical parameters. The SL175FX is the preferred selection for new designs and ongoing procurement due to its active product status and ROHS3 compliance, which aligns with current regulatory requirements. The SL175F remains suitable for legacy system maintenance where existing inventory is available, though long-term availability is limited due to obsolescence.

Frequently Asked Questions (FAQ)

Q: Can SL175FX be used as a direct replacement for SL175F in existing assemblies?

A: Yes. Both parts are identical in connector type, position count, shell size, mounting configuration, termination method, and electrical ratings. Physical and functional compatibility is complete.

Q: What is the primary difference between SL175F and SL175FX?

A: Product status and regulatory compliance. SL175F is obsolete with RoHS non-compliance, while SL175FX is active with ROHS3 compliance. All electrical and mechanical specifications are equivalent.

Q: Are there packaging differences between these parts?

A: SL175F packaging is not specified in available data. SL175FX is supplied in bulk packaging. Confirm packaging requirements with your procurement specification.

Q: What applications are supported by these connectors?

A: Both parts are suitable for audio, industrial, marine, and medical applications.

Q: Is the 5A current rating sufficient for my application?

A: Current rating is a fixed specification. Verify that 5A meets your circuit requirements before component selection.
