Key Parameters

Substitute Part Grouping Explanation

Substitution of the ACT90MG41PA is determined by strict adherence to the following parameters:

Critical Matching Parameters:

• Connector type (Receptacle, Male Pins)
• Number of positions (41)
• Shell size designation (21-41)
• MIL-DTL-38999 Series III compliance
• Mounting configuration (Panel Mount, Flange)
• Termination method (Crimp)
• Fastening type (Threaded)
• Shielding requirement (Shielded)
• Contact finish (Gold)
• Contact material (Copper Alloy)
• Orientation (A)

The CTVP00RW-21-41PA manufactured by Amphenol Aerospace Operations satisfies all critical matching parameters. Both connectors are MIL-DTL-38999 Series III compliant circular connectors with identical position counts, shell sizes, mounting configurations, and electrical contact specifications. The substitute part maintains the same crimp termination, threaded fastening, and shielded design required for aerospace and military applications.

Parameter Comparison

Engineering Selection Recommendations

The CTVP00RW-21-41PA is a direct functional equivalent for the discontinued ACT90MG41PA based on the following engineering criteria:

Compliance and Standardization: Both connectors comply with MIL-DTL-38999 Series III specifications, ensuring interchangeability within military and aerospace systems designed to this standard. Both maintain identical electrical contact specifications, including copper alloy material, gold plating at 50.0µin thickness, and shielded construction.

Mechanical Compatibility: The connectors share identical shell sizes (21-41), mounting configurations (panel mount with flange), fastening methods (threaded), and termination approaches (crimp). These parameters ensure mechanical fit and installation compatibility in existing applications.

Product Availability: The CTVP00RW-21-41PA is currently active in production with 925 units in stock, whereas the ACT90MG41PA is discontinued. This availability difference makes the Amphenol Aerospace part the practical selection for new procurement and system maintenance.

Temperature Consideration: The ACT90MG41PA operates to 200°C, while the CTVP00RW-21-41PA operates to 175°C. Applications requiring operation above 175°C require evaluation against specific system thermal requirements.

Regulatory Status: Both parts are RoHS non-compliant and carry identical MSL ratings (1 - Unlimited), maintaining equivalent handling and storage requirements.

Frequently Asked Questions (FAQ)

Q: Can the CTVP00RW-21-41PA directly replace the ACT90MG41PA in existing assemblies?

A: Yes, for applications operating at or below 175°C. Both connectors are MIL-DTL-38999 Series III compliant with identical 41-position configurations, shell sizes, mounting features, and crimp termination specifications. The connectors are mechanically and electrically interchangeable within these thermal limits.

Q: What is the significance of the operating temperature difference between the two parts?

A: The ACT90MG41PA is rated to 200°C, while the CTVP00RW-21-41PA is rated to 175°C. Systems designed to operate above 175°C must evaluate whether the substitute part meets thermal requirements. Systems operating at or below 175°C experience no functional limitation from this specification difference.

Q: Are the shell finishes compatible between the two connectors?

A: The shell finishes differ: the ACT90MG41PA features nickel finish with silver color, while the CTVP00RW-21-41PA features olive drab cadmium finish. Both finishes provide corrosion resistance suitable for aerospace and military applications. The finish difference does not affect electrical or mechanical compatibility but may impact visual identification and environmental specifications in specific applications.

Q: What is the current rating for the CTVP00RW-21-41PA?

A: The current rating for the CTVP00RW-21-41PA is not specified in the available technical data. The ACT90MG41PA carries a 7.5A rating. Applications requiring confirmation of current-carrying capacity for the substitute part should consult the manufacturer's detailed specifications.

Q: Are both connectors suitable for the same application categories?

A: Both connectors are designated for aerospace and military applications. The CTVP00RW-21-41PA additionally lists aviation and marine applications. Both parts maintain identical MIL-DTL-38999 Series III compliance and shielded construction required for these demanding environments.

Q: What is the packaging difference between the two parts?

A: The ACT90MG41PA packaging is not specified in the available data. The CTVP00RW-21-41PA is supplied in bulk packaging. Packaging differences do not affect connector functionality or compatibility.

Q: Do both connectors require the same crimp tool specifications?

A: Both connectors use crimp termination with copper alloy contacts. Crimp tool compatibility depends on the specific contact gauge and crimp specifications, which are not detailed in the provided parameters. Consult the respective manufacturer's termination documentation to confirm tool compatibility.
