Key Parameters

Substitute Part Grouping Explanation

Substitution for the MS3116F18-32P is determined by the following critical parameters:

• Connector type and gender (Plug, Male Pins)
• Position count (32 positions)
• Shell size designation (18-32)
• Fastening mechanism (Bayonet Lock)
• Termination method (Solder or Solder Cup)
• Operating temperature range (-55°C ~ 125°C)
• Environmental resistance capability
• Mechanical compatibility with MIL-DTL-26482 style connectors

The MSW06E18-32P-SR qualifies as a substitute based on matching these core parameters while maintaining functional equivalence for the intended applications.

Parameter Comparison

Engineering Selection Recommendations

The MSW06E18-32P-SR is a direct functional equivalent for the discontinued MS3116F18-32P. Both connectors maintain identical mechanical interfaces, position counts, and operating temperature specifications required for military and aerospace applications.

The substitute part offers the advantage of active product status, ensuring ongoing availability for procurement and system support. Both parts maintain RoHS non-compliant status, consistent with military specification requirements. The MSW06E18-32P-SR provides specified electrical ratings (7.5A at 800V), which may be beneficial for applications requiring documented electrical performance parameters.

The termination difference (Solder Cup versus Solder) represents a minor variation in the connection method to the cable assembly. Both termination types are compatible with standard wire attachment procedures for this connector class.

Frequently Asked Questions (FAQ)

Q: Can the MSW06E18-32P-SR directly replace the MS3116F18-32P in existing assemblies?

A: Yes. Both connectors share identical shell sizes (18-32), position counts (32), fastening mechanisms (Bayonet Lock), and operating temperature ranges (-55°C ~ 125°C). The mechanical interface is compatible for direct substitution in free-hanging, in-line mounting configurations.

Q: What is the difference between Solder Cup and Solder termination?

A: Solder Cup termination features a cup-shaped contact designed for wire insertion and solder attachment. Solder termination uses a standard solder connection point. Both methods achieve equivalent electrical and mechanical connections for circular connector applications.

Q: Are both parts suitable for military and aerospace applications?

A: Yes. Both the MS3116F18-32P and MSW06E18-32P-SR conform to MIL-DTL-26482 style specifications and are rated for military applications. Both maintain RoHS non-compliant status, which is standard for military-grade connectors.

Q: What is the inventory status for the substitute part?

A: The MSW06E18-32P-SR is currently active with 767 pieces in stock, providing reliable availability compared to the discontinued MS3116F18-32P.

Q: Do the electrical ratings differ between these parts?

A: The MSW06E18-32P-SR specifies 7.5A current rating and 800V voltage rating. The MS3116F18-32P does not provide specified electrical ratings in the available documentation. For applications requiring documented electrical performance, the substitute part provides explicit rating parameters.
