Key Parameters

Substitute Part Grouping Explanation

Substitution for the MS3116F16-26S is determined by the following critical parameters:

• Connector Type & Gender: Plug with female sockets (receptacle contacts)
• Position Count: 26 positions
• Shell Size: 16-26 insert designation
• Fastening Mechanism: Bayonet lock coupling
• Termination Method: Solder connection (solder cup or equivalent solder termination)
• Mounting Configuration: Free hanging, in-line orientation
• Environmental Rating: Environment resistant classification
• Operating Temperature: -55°C to 125°C capability
• Shell Material: Aluminum construction

The substitute part MSW06E16-26S-SR meets these core substitution criteria and is classified as a 26482 Style Connector, maintaining mechanical and electrical compatibility within the MIL-DTL-26482 specification family.

Parameter Comparison

Engineering Selection Recommendations

The MSW06E16-26S-SR is a suitable substitute for the MS3116F16-26S based on the following factors:

Mechanical Compatibility: Both connectors share identical shell size (16-26), position count (26), fastening mechanism (bayonet lock), and mounting configuration (free hanging, in-line). Physical mating and installation compatibility is maintained.

Electrical Compatibility: Both connectors operate across the same temperature range (-55°C to 125°C) and provide environment resistant ingress protection. The substitute part specifies current and voltage ratings (7.5A, 800V), whereas the main part does not provide these specifications in the available data.

Series Alignment: The substitute is classified as a 26482 Style Connector, maintaining alignment with the MIL-DTL-26482 specification family to which the main part conforms.

Product Availability: The MS3116F16-26S is discontinued at DiGi Electronics. The MSW06E16-26S-SR is currently active with 1064 pieces in stock, providing immediate availability for procurement.

Compliance Status: Both parts are RoHS non-compliant and carry the same ECCN classification (EAR99), maintaining regulatory consistency in applications where the original part was specified.

Frequently Asked Questions (FAQ)

Q: Can the MSW06E16-26S-SR directly replace the MS3116F16-26S in existing assemblies?

A: Yes, within the constraints of the provided specifications. Both connectors share identical shell size, position count, fastening type, and mounting configuration. Physical and mechanical compatibility is maintained. Electrical compatibility is supported by matching operating temperature ranges and environment resistant ratings. Verification of application-specific requirements (current, voltage, and signal integrity) is the responsibility of the design engineer.

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

A: The primary differences are manufacturer (Amphenol vs. Milspecwest), shell finish (Olive Drab Chromate over Cadmium vs. Cadmium), contact finish (Gold vs. Cadmium), and documented electrical ratings. The substitute part includes specified current (7.5A) and voltage (800V) ratings, whereas the main part does not provide these values in the available data. Both maintain the same mechanical form factor and environmental specifications.

Q: Are there any compatibility concerns with the different shell finishes?

A: Both connectors use aluminum shells with cadmium-based finishes. The main part specifies Olive Drab Chromate over Cadmium, while the substitute specifies Cadmium finish. Both finishes provide corrosion resistance and environmental protection. Finish differences do not affect mechanical mating or electrical performance.

Q: What is the significance of the "26482 Style" classification for the substitute part?

A: The 26482 Style designation indicates conformance to the MIL-DTL-26482 specification family. This classification ensures that the substitute part meets the same dimensional, mechanical, and performance standards as the original MS3116F16-26S, which is specified as MIL-DTL-26482 Series I.

Q: How do the contact finishes differ, and does this affect substitution?

A: The main part specifies gold contact finish for mating surfaces, while the substitute specifies cadmium contact finish. Both finishes provide electrical conductivity and corrosion resistance. Contact finish selection depends on application-specific requirements for signal integrity, wear resistance, and environmental exposure. This difference should be evaluated within the context of the specific application.

Q: Is the strain relief feature on the substitute part a significant difference?

A: The substitute part includes a strain relief feature, while the main part lists a cable clamp as a feature. Strain relief provides mechanical protection to the cable at the connector interface. This feature enhances durability in applications subject to cable flexing or vibration. The presence of strain relief on the substitute part does not prevent substitution and may provide additional mechanical protection.
