Key Parameters

Substitute Part Grouping Explanation

Substitution of the SL185F 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 - Rear Side Nut)
• Termination method (Solder Eyelet)
• Fastening mechanism (Threaded)
• Orientation (D)
• Electrical rating (5A current capacity)
• Material specifications (Zinc Die Cast shell, Nickel finish, Silver contact finish, Copper Alloy contacts)
• Flammability compliance (UL94 V-0)

The SL185FX meets all these criteria and is classified as an active product, making it a direct functional equivalent for the obsolete SL185F.

Parameter Comparison

Engineering Selection Recommendations

The SL185FX is the direct equivalent for the obsolete SL185F. Both connectors share identical mechanical, electrical, and material specifications within the Slim-Line® SL18 series. The primary distinction is product status and regulatory compliance:

The SL185F is obsolete and carries RoHS non-compliant status. The SL185FX is an active product with ROHS3 compliance, making it the appropriate selection for new designs and ongoing production requiring regulatory adherence. Both parts maintain identical form, fit, and function characteristics, ensuring direct interchangeability in applications requiring 5-position circular receptacle connectors with solder eyelet termination.

Frequently Asked Questions (FAQ)

Q: Can the SL185FX directly replace the SL185F in existing assemblies?

A: Yes. The SL185FX is mechanically and electrically identical to the SL185F. Both connectors feature the same 5-position configuration, SL-5F shell size, panel mount bulkhead installation, solder eyelet termination, and 5A current rating. Direct substitution is supported without design modification.

Q: What is the difference between SL185F and SL185FX?

A: The SL185F is classified as obsolete with RoHS non-compliant status. The SL185FX is an active product with ROHS3 compliance. All functional and mechanical parameters are identical.

Q: Are there packaging differences between these parts?

A: The SL185FX is supplied in bulk packaging. Packaging specifications for the SL185F are not provided in the technical data. Confirm packaging requirements with your procurement department.

Q: What applications are supported by these connectors?
