Key Parameters

Substitute Part Grouping Explanation

Substitution of the MS3111E16-23P is determined by strict alignment of the following parameters:

• Connector Configuration: Receptacle type with male pins, 23-position arrangement
• Shell Size: Insert size 16-23 with bayonet lock fastening mechanism
• Termination Method: Solder-based connection (solder cup or equivalent solder termination)
• Environmental Rating: Environment resistant classification
• Operating Temperature: -55°C to 125°C range
• Mechanical Compatibility: Free hanging, in-line mounting orientation

The MSW01E16-23P meets these substitution criteria as a 23-position circular connector receptacle with male pins, matching shell size 16-23, bayonet lock fastening, and identical operating temperature range. Both connectors are specified for military applications and maintain environmental resistance ratings.

Parameter Comparison

Engineering Selection Recommendations

The MSW01E16-23P from Milspecwest, LLC serves as a functional equivalent for the discontinued MS3111E16-23P. Selection between these components should be based on the following factors:

Product Availability: The MS3111E16-23P is discontinued at DiGi Electronics. The MSW01E16-23P is currently active with 942 pieces in stock, providing immediate procurement availability.

Compliance Status: The MS3111E16-23P carries REACH Affected status with EAR99 ECCN classification. The MSW01E16-23P is RoHS non-compliant with Vendor Undefined REACH status. Systems requiring specific compliance certifications must evaluate regulatory requirements against substitute part documentation.

Electrical Specifications: The MSW01E16-23P provides documented voltage (800V) and current ratings (7.5A, 13A), whereas the original part does not specify these parameters. Applications requiring explicit electrical performance verification should reference the MSW01E16-23P datasheet.

Mechanical Compatibility: Both connectors maintain identical shell size, position count, fastening mechanism, and mounting configuration, ensuring direct mechanical interchangeability in existing installations.

Frequently Asked Questions (FAQ)

Q: Can the MSW01E16-23P directly replace the MS3111E16-23P in existing assemblies?

A: Yes, from a mechanical and functional standpoint. Both connectors share identical shell size (16-23), position count (23), fastening type (bayonet lock), termination method (solder-based), and operating temperature range (-55°C to 125°C). However, compliance and regulatory requirements must be evaluated for your specific application.

Q: What are the key differences between these two connectors?

A: The primary differences are manufacturer (Amphenol vs. Milspecwest), product status (discontinued vs. active), shell finish (olive drab chromate over cadmium vs. cadmium), contact finish (gold vs. cadmium), and documented electrical ratings. The MSW01E16-23P provides explicit voltage and current specifications absent from the original part.

Q: Are there packaging differences between these connectors?

A: Yes. The MS3111E16-23P packaging is not specified in available documentation. The MSW01E16-23P is supplied in bag packaging. Verify packaging requirements for your assembly and storage procedures.

Q: Which connector should I select for new designs?

A: The MSW01E16-23P is the appropriate choice for new designs, as it is currently active and available. The MS3111E16-23P is discontinued and should not be specified for new development.

Q: Do these connectors meet military specifications?

A: Both connectors are specified for military applications. The MS3111E16-23P is explicitly designated as MIL-DTL-26482 Series I. The MSW01E16-23P is classified as a 26482 Style Connector. Verify specific military standard compliance requirements for your application.

Q: What is the difference between solder cup and solder termination?

A: Both termination methods use solder for electrical connection. Solder cup termination features a cup-shaped contact designed to accept wire leads. Both connectors in this comparison use solder-based termination suitable for wire attachment.
