Key Parameters

Substitute Part Grouping Explanation

The MSW00E8-4P-SR qualifies as a functional equivalent based on the following critical parameters:

• Connector Configuration: Both parts are 4-position circular connector receptacles with male pins
• Shell Size: Identical 8-4 shell size and insert configuration
• Mounting Architecture: Both feature panel mount with flange mounting and bayonet lock fastening
• Shell Material: Aluminum construction in both parts
• Temperature Rating: Matching -55°C ~ 125°C operating range
• Series Compliance: MSW00E8-4P-SR is a 26482 Style Connector, maintaining MIL-DTL-26482 series compatibility
• Military Application: Both parts are designated for military use

The primary difference lies in termination method: MS3110F8-4P uses solder cup termination, while MSW00E8-4P-SR uses solder termination. Both are solder-based connection methods suitable for equivalent circuit integration.

Parameter Comparison

Engineering Selection Recommendations

The MSW00E8-4P-SR serves as a direct functional substitute for the discontinued MS3110F8-4P based on matching mechanical and electrical interface parameters. Both connectors maintain MIL-DTL-26482 series compliance and identical shell size, position count, and mounting configuration. The MSW00E8-4P-SR is currently active in production, providing supply continuity for applications requiring 4-position circular connectors with bayonet lock fastening and panel mount configuration.

Both parts carry non-compliant RoHS status, consistent with military-grade connector specifications. The MSW00E8-4P-SR provides specified current and voltage ratings (7.5A, 800V), whereas the original part does not list these parameters. Selection should be based on application requirements and existing system integration specifications.

Frequently Asked Questions (FAQ)

Q: Can MSW00E8-4P-SR directly replace MS3110F8-4P in existing assemblies?

A: Yes. Both connectors share identical shell size (8-4), position count (4), mounting configuration (panel mount with flange), and fastening method (bayonet lock). The mechanical and electrical interfaces are equivalent.

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 connection. Solder termination uses a flat or formed contact surface for solder connection. Both are solder-based methods suitable for equivalent circuit integration.

Q: Are both connectors suitable for military applications?

A: Yes. Both MS3110F8-4P and MSW00E8-4P-SR are designated for military applications and comply with MIL-DTL-26482 series specifications.

Q: What is the operating temperature range for these connectors?

A: Both connectors operate across -55°C to 125°C, meeting military environmental specifications.

Q: Why is the original MS3110F8-4P discontinued?

A: The MS3110F8-4P is discontinued at DiGi Electronics. The MSW00E8-4P-SR remains in active production and provides equivalent functionality for ongoing system support.

Q: Are there RoHS compliance considerations?

A: Both connectors are RoHS non-compliant, consistent with military-grade connector standards. Applications requiring RoHS compliance should evaluate alternative connector families.
