Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MS3110E8-4P is determined by strict alignment with the following critical parameters:

Mandatory Matching Parameters:

• Number of Positions: 4
• Shell Size - Insert: 8-4
• Connector Type: Receptacle, Male Pins
• Mounting Type: Panel Mount
• Mounting Feature: Flange
• Fastening Type: Bayonet Lock
• Operating Temperature Range: -55°C ~ 125°C
• Series Compliance: MIL-DTL-26482 or equivalent military standard

Acceptable Variations:

• Shell Finish: Cadmium or Olive Drab Chromate over Cadmium
• Contact Finish - Mating: Gold or Cadmium
• Termination Type: Solder Cup or Solder (without cup specification)

The MSW00E8-4P from Milspecwest, LLC qualifies as a substitute based on matching all mandatory parameters and operating within acceptable finish variations.

Parameter Comparison

Engineering Selection Recommendations

The MSW00E8-4P is a qualified substitute for the MS3110E8-4P based on functional and mechanical compatibility. Both connectors comply with MIL-DTL-26482 military standards, maintain identical shell size, position count, mounting configuration, and operating temperature specifications.

The primary differences are:

Contact Finish: The MS3110E8-4P features gold mating contact finish, while the MSW00E8-4P uses cadmium. Both finishes provide corrosion resistance suitable for military and aerospace environments.

Termination Detail: The MS3110E8-4P specifies solder cup termination; the MSW00E8-4P specifies solder termination. Both are compatible with standard PCB assembly processes.

Product Availability: The MS3110E8-4P is discontinued at DiGi Electronics. The MSW00E8-4P is currently active with 781 pieces in stock, providing immediate procurement availability.

Both parts carry identical RoHS non-compliant and EAR99 export control classifications, maintaining regulatory consistency for military and aerospace applications.

Frequently Asked Questions (FAQ)

Q: Can the MSW00E8-4P directly replace the MS3110E8-4P in existing designs?

A: Yes. Both connectors share identical shell size (8-4), position count (4), mounting configuration (panel mount flange), fastening method (bayonet lock), and operating temperature range (-55°C to 125°C). The connectors are mechanically and functionally interchangeable.

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

A: Solder cup termination includes a cup-shaped contact receptacle for wire insertion before soldering. Solder termination refers to direct solder connection points. Both methods achieve equivalent electrical and mechanical connections in PCB assembly.

Q: Does the cadmium contact finish on the MSW00E8-4P affect performance compared to the gold finish on the MS3110E8-4P?

A: Both cadmium and gold finishes provide corrosion resistance and electrical conductivity suitable for military and aerospace applications. Contact finish selection depends on specific environmental exposure and signal integrity requirements of the application.

Q: Are both parts compliant with the same military standards?

A: Yes. The MS3110E8-4P is specified as MIL-DTL-26482 Series I. The MSW00E8-4P is specified as 26482 Style Connectors, indicating compliance with the same military standard family.

Q: What is the inventory status for each part?

A: The MS3110E8-4P is discontinued at DiGi Electronics with 744 pieces listed as new original in stock. The MSW00E8-4P is active with 781 pieces in stock, providing ongoing procurement availability.

Q: Are there any export control restrictions on these parts?

A: Both parts carry ECCN classification EAR99, indicating they are subject to the same export control regulations. No additional restrictions apply to the substitute part.
