MS3111F16-26P Equivalent & Substitute Parts

Part Overview

The MS3111F16-26P is a 26-position circular connector receptacle with male pins, manufactured by Amphenol Industrial Operations to MIL-DTL-26482 Series I specifications. This connector features solder cup termination, bayonet lock fastening, and is designed for aerospace, military, communication, and industrial applications. The part is discontinued at DiGi Electronics, necessitating identification of equivalent substitute components that maintain functional and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MS3111F16-26P is determined by strict alignment of the following parameters:

• Connector type and pin configuration (Receptacle, Male Pins, 26 positions)
• Shell size and insert designation (16-26)
• Mounting configuration (Free Hanging, In-Line)
• Fastening mechanism (Bayonet Lock)
• Shell material (Aluminum)
• Operating temperature range (-55°C ~ 125°C)
• Series compliance (MIL-DTL-26482 style)

The substitute part MSW01E16-26P-SR meets these core requirements. While termination differs (solder vs. solder cup), both are solder-based termination methods compatible with the same contact interface. The substitute maintains electrical and mechanical interchangeability within the specified parameter set.

Parameter Comparison

Engineering Selection Recommendations

The MSW01E16-26P-SR serves as a functional equivalent to the discontinued MS3111F16-26P based on matching core mechanical and electrical interface parameters. The substitute maintains identical shell size, position count, mounting configuration, and operating temperature range.

Key considerations for selection:

Contact finish differs between the main part (gold) and substitute (cadmium). This distinction affects corrosion resistance and contact reliability in specific environmental conditions. The gold finish of the original part provides superior corrosion resistance; the cadmium finish of the substitute is suitable for standard military and industrial environments.

Shell finish also differs (Olive Drab Chromate over Cadmium vs. Cadmium). Both finishes provide environment-resistant protection appropriate for military applications.

The substitute is currently active in inventory, whereas the main part is discontinued. Both components are RoHS non-compliant, consistent with military specification requirements.

Termination method differs slightly (solder cup vs. solder), but both are solder-based termination compatible with the same contact interface and PCB assembly processes.

Frequently Asked Questions (FAQ)

Q: Can MSW01E16-26P-SR directly replace MS3111F16-26P in existing assemblies?

A: Yes, for mechanical and electrical interface compatibility. The 26-position shell size 16-26 receptacle with bayonet lock fastening is identical. Verify that the contact finish (cadmium vs. gold) and shell finish (cadmium vs. olive drab chromate) meet your specific environmental and corrosion resistance requirements.

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

A: Both are solder-based termination methods. Solder cup termination uses a cup-shaped contact designed for wire insertion and solder flow. Solder termination uses a flat or formed contact surface for solder attachment. Both are compatible with standard solder assembly processes for this connector series.

Q: Are there electrical rating differences between the main part and substitute?

A: The main part (MS3111F16-26P) does not specify current or voltage ratings in the provided data. The substitute (MSW01E16-26P-SR) is rated for 7.5A at 800V. Verify these ratings against your circuit requirements.

Q: Does the substitute maintain MIL-DTL-26482 compliance?

A: The substitute is designated as a 26482 Style Connector. Both the main part and substitute are RoHS non-compliant, consistent with military specification requirements. Confirm specific compliance requirements with your procurement or quality assurance department.

Q: What inventory status should influence my selection?

A: The main part is discontinued at DiGi Electronics with 984 pieces in stock. The substitute is active with 1056 pieces in stock. For long-term supply chain stability, the active substitute is preferable.
