Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MS3116E8-3P is determined by the following critical parameters:

• Connector Configuration: Plug with male pins, 3-position arrangement
• Shell Size Compatibility: 8-3 insert size for mechanical fit with mating receptacles
• Termination Method: Solder cup or solder termination for wire attachment
• Fastening Mechanism: Bayonet lock coupling for secure mating
• Environmental Rating: Environment resistant classification for operational reliability
• Operating Temperature: -55°C to 125°C range for thermal compatibility
• Mounting Style: Free hanging in-line configuration

The MSW06E8-3P meets all critical substitution criteria, maintaining identical connector type, position count, shell size, fastening method, and operating temperature range. Both parts comply with MIL-DTL-26482 series specifications and support equivalent military and aerospace applications.

Parameter Comparison

Engineering Selection Recommendations

The MSW06E8-3P is a direct functional equivalent for the MS3116E8-3P based on matching mechanical and electrical specifications. Selection between these parts should consider:

Product Availability: The MS3116E8-3P is discontinued at DiGi Electronics, while the MSW06E8-3P maintains active production status with 1162 units in stock, ensuring supply chain continuity.

Compliance Alignment: Both parts share identical RoHS non-compliant and EAR99 ECCN classifications, maintaining regulatory consistency in applications requiring these designations.

Electrical Performance: The MSW06E8-3P provides specified current (7.5A) and voltage (800V) ratings, whereas the main part does not list these values. For applications where electrical specifications are critical, the MSW06E8-3P offers documented performance parameters.

Termination Compatibility: Both parts utilize solder termination methods suitable for wire attachment in aerospace, military, and industrial systems. The solder cup and solder termination approaches are functionally equivalent for this connector class.

Frequently Asked Questions (FAQ)

Q: Can the MSW06E8-3P directly replace the MS3116E8-3P in existing assemblies?

A: Yes. Both connectors share identical shell size (8-3), position count (3), fastening type (bayonet lock), and operating temperature range (-55°C to 125°C). The mechanical and electrical interfaces are compatible with mating receptacles designed for MIL-DTL-26482 series connectors.

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 refers to the general solder-based wire attachment method. Both approaches provide equivalent electrical and mechanical connections for this connector category.

Q: Are there compliance differences between these parts?

A: Both parts are RoHS non-compliant and classified as EAR99 for export control purposes. No compliance advantage exists between the two options for regulated applications.

Q: Why is the MS3116E8-3P discontinued?

A: Discontinuation at DiGi Electronics reflects supplier inventory decisions and does not indicate technical obsolescence. The MSW06E8-3P remains available as an active equivalent for ongoing procurement needs.

Q: What packaging format is the MSW06E8-3P supplied in?

A: The MSW06E8-3P is supplied in bag packaging, suitable for standard component handling and storage in military and aerospace supply chains.
