Key Parameters

Substitute Part Grouping Explanation

Substitution of the MS3116F12-8S is determined by the following critical parameters:

• Connector Type & Position Count: Must be plug configuration with 8 female sockets
• Shell Size: Must maintain 12-8 shell size and insert compatibility for mechanical fit
• Fastening Mechanism: Bayonet lock fastening required for proper mating interface
• Termination Method: Solder or solder cup termination acceptable for electrical connection
• Operating Temperature: Must support -55°C ~ 125°C range
• Environmental Rating: Environment resistant classification required
• Mounting Configuration: Free hanging (in-line) mounting type

The MSW06E12-8S-SR qualifies as a substitute based on matching all critical parameters within the allowed electrical and mechanical specifications for this product category.

Parameter Comparison

Engineering Selection Recommendations

The MSW06E12-8S-SR serves as a direct substitute for the discontinued MS3116F12-8S based on mechanical and electrical parameter alignment. Both connectors maintain identical shell size (12-8), position count (8), fastening mechanism (bayonet lock), and operating temperature range (-55°C ~ 125°C).

The MSW06E12-8S-SR is currently in active production status with 1180 pieces available in inventory, providing supply continuity for applications previously using the MS3116F12-8S. Both parts are classified as RoHS non-compliant and carry EAR99 ECCN designation, maintaining equivalent regulatory compliance profiles.

The substitute part includes strain relief features and specifies current and voltage ratings (7.5A at 800V), providing additional electrical performance documentation compared to the main part specification.

Frequently Asked Questions (FAQ)

Q: Can the MSW06E12-8S-SR directly replace the MS3116F12-8S in existing assemblies?

A: Yes. Both connectors share identical shell size (12-8), position count (8), bayonet lock fastening, and operating temperature range (-55°C ~ 125°C). Mechanical and electrical compatibility is maintained for direct substitution in free hanging (in-line) mounting applications.

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

A: Both termination methods provide solder-based electrical connections. Solder cup termination features a cup-shaped contact receptacle, while solder termination uses standard solder connection points. Both are compatible for this connector category.

Q: Are there any compliance differences between the two parts?

A: Both parts are RoHS non-compliant and carry EAR99 ECCN classification. Regulatory compliance profiles are equivalent for military and industrial applications.

Q: What inventory status should be considered for procurement?

A: The MS3116F12-8S is discontinued at DiGi Electronics. The MSW06E12-8S-SR is active production with 1180 pieces currently in stock, ensuring supply availability for new orders and system maintenance.

Q: Are the contact finish specifications compatible?

A: The MS3116F12-8S specifies gold contact finish for mating surfaces. The MSW06E12-8S-SR specifies cadmium contact finish. Both finishes are acceptable for the MIL-DTL-26482 Series I connector category and maintain electrical performance within specified operating parameters.
