Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MSW06A22-55P is determined by the following critical parameters:

Mandatory Matching Parameters:

• Connector Type: Plug, Male Pins
• Number of Positions: 55
• Shell Size - Insert: 22-55
• Mounting Type: Free Hanging (In-Line)
• Fastening Type: Bayonet Lock
• Shell Material: Aluminum
• Operating Temperature Range: -55°C ~ 125°C
• Series Compliance: MIL-DTL-26482 or equivalent

The PT06A-22-55P from Amphenol Industrial Operations satisfies all mandatory matching parameters and is classified as a direct substitute. Both connectors conform to the same military specification series, maintain identical mechanical interfaces, and support the same operational environment.

Parameter Comparison

Engineering Selection Recommendations

Both the MSW06A22-55P and PT06A-22-55P are active products with identical mechanical and electrical compatibility. Selection between these parts should be based on the following factors:

Availability and Lead Time: The PT06A-22-55P maintains higher inventory levels (1133 pcs) compared to the MSW06A22-55P (1046 pcs), which may influence procurement timelines.

Compliance Status: Both connectors are RoHS non-compliant and carry the same ECCN classification (EAR99), indicating equivalent regulatory treatment for export and military applications.

Termination Method: The MSW06A22-55P utilizes direct solder termination, while the PT06A-22-55P employs solder cup termination. This difference requires evaluation based on assembly process requirements and cable preparation specifications.

Contact Finish: The MSW06A22-55P features cadmium contact finish, while the PT06A-22-55P provides gold contact finish. Gold plating offers enhanced corrosion resistance and is suitable for applications requiring extended shelf life or exposure to corrosive environments.

Shell Finish: The MSW06A22-55P has cadmium shell finish, whereas the PT06A-22-55P features olive drab chromate over cadmium. The PT06A-22-55P configuration provides additional corrosion protection suitable for aerospace and military applications.

Frequently Asked Questions (FAQ)

Q: Can the PT06A-22-55P directly replace the MSW06A22-55P in existing assemblies?

A: Yes. Both connectors share identical mechanical interfaces, including shell size (22-55), bayonet lock fastening, and free-hanging mounting configuration. The connectors are physically and electrically interchangeable at the mating interface.

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

A: Solder termination involves direct soldering of wire to the connector pin. Solder cup termination features a cup-shaped receptacle on the pin designed to accept and retain solder. Solder cup termination provides improved solder joint reliability and is preferred in high-vibration or thermal cycling applications.

Q: Are there differences in electrical performance between these connectors?

A: The MSW06A22-55P specifies a current rating of 7.5A and voltage rating of 800V. The PT06A-22-55P does not provide explicit current and voltage ratings in the available documentation. For applications requiring specific electrical performance verification, the manufacturer's detailed specifications should be consulted.

Q: How do the contact finishes affect connector performance?

A: Cadmium contact finish (MSW06A22-55P) provides baseline electrical conductivity and corrosion resistance. Gold contact finish (PT06A-22-55P) offers superior corrosion resistance, lower contact resistance, and extended operational life in harsh environments. Gold plating is preferred for applications with extended storage periods or exposure to moisture and salt spray.

Q: What is the significance of the shell finish difference?

A: The MSW06A22-55P features cadmium shell finish, while the PT06A-22-55P provides olive drab chromate over cadmium. Chromate conversion coating enhances corrosion resistance and is standard for aerospace and military applications. This difference does not affect electrical performance but improves environmental durability.

Q: Are both connectors suitable for military applications?

A: Yes. Both connectors are designed for military applications and comply with MIL-DTL-26482 specifications. The PT06A-22-55P additionally supports aerospace, industrial, instrumentation, and mass transit applications.

Q: What is the moisture sensitivity level (MSL) consideration?

A: The MSW06A22-55P lists MSL as Not Applicable. The PT06A-22-55P specifies MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling. This difference does not affect field performance but may influence procurement and storage procedures.
