Key Parameters

Substitute Part Grouping Explanation

Substitution of the ACT90MF32PA is determined by strict adherence to the following critical parameters:

Mandatory Matching Parameters:

• Number of Positions: 32
• Shell Size - Insert: 19-32
• Connector Type: Receptacle with Male Pins
• Mounting Type: Panel Mount with Flange
• Fastening Type: Threaded
• Orientation: A
• Termination: Crimp
• Shielding: Shielded
• Series Compliance: MIL-DTL-38999 Series III
• Ingress Protection: Environment Resistant

Operational Parameters:

• Operating Temperature Range: Must accommodate -65°C minimum and 200°C maximum
• Current Rating: 7.5A minimum
• Contact Finish: Gold mating surface
• Environmental Classification: Aerospace and Military applications

The substitute part CTVP00RW-19-32AA from Amphenol Aerospace Operations meets these mandatory parameters within the MIL-DTL-38999 Series III specification family, though with specific operational and material variations noted in the parameter comparison table.

Parameter Comparison

Engineering Selection Recommendations

Primary Consideration: Product Availability

The ACT90MF32PA is discontinued at DiGi Electronics. The CTVP00RW-19-32AA is currently active in inventory with 1010 pieces available, providing supply continuity for new designs and replacement applications.

Compliance and Certification

Both parts comply with MIL-DTL-38999 Series III specifications and maintain identical RoHS non-compliant status and Moisture Sensitivity Level 1 ratings. Both are classified under ECCN EAR99 for export control purposes.

Operating Temperature Limitation

The substitute part CTVP00RW-19-32AA operates to a maximum of 175°C, compared to the main part's 200°C rating. Applications requiring sustained operation above 175°C cannot use this substitute without thermal performance verification.

Material and Finish Differences

The substitute features cadmium shell finish and olive drab housing color, compared to the main part's nickel finish and silver color. These differences do not affect electrical performance but may impact corrosion resistance profiles and visual identification in system integration.

Contact Finish Specification

The main part specifies gold mating contact finish with 50.0µin thickness. The substitute part does not provide explicit contact finish specification, requiring clarification from the manufacturer for applications with specific contact resistance or corrosion requirements.

Frequently Asked Questions (FAQ)

Q: Can CTVP00RW-19-32AA directly replace ACT90MF32PA in all applications?

A: The CTVP00RW-19-32AA is functionally equivalent for applications operating at or below 175°C. Applications requiring operation above 175°C require alternative solutions. Both parts maintain MIL-DTL-38999 Series III compliance and identical position count, mounting configuration, and termination method.

Q: What is the significance of the different shell finishes (Nickel vs. Cadmium)?

A: Shell finish affects corrosion resistance and environmental durability. Nickel provides different corrosion characteristics than cadmium. System designers must evaluate environmental exposure conditions to determine if the cadmium finish of the substitute meets application requirements.

Q: Are the contact finishes equivalent between the two parts?

A: The main part specifies gold mating contact finish at 50.0µin thickness. The substitute part does not provide explicit contact finish specification. For applications with specific contact resistance, signal integrity, or corrosion requirements, contact finish compatibility must be confirmed with the manufacturer.

Q: Does the housing color difference affect electrical performance?

A: Housing color is a visual identification feature and does not affect electrical performance. The olive drab color of the substitute versus the silver color of the main part is a cosmetic difference relevant only to system integration and identification protocols.

Q: What is the impact of the 25°C maximum temperature reduction?

A: The substitute part's 175°C maximum operating temperature is 25°C lower than the main part's 200°C rating. Applications with sustained thermal loads approaching or exceeding 175°C must either select alternative parts or conduct thermal analysis to confirm the substitute's suitability.

Q: Are both parts suitable for aerospace and military applications?

A: Both parts are specified for aerospace and military applications and maintain MIL-DTL-38999 Series III compliance. However, specific program requirements, qualification status, and procurement specifications must be verified with the end-use authority.

Q: What does "Contacts Not Included" mean for the substitute part?

A: The CTVP00RW-19-32AA is a receptacle housing assembly without pre-installed contacts. Crimp contacts must be sourced separately and installed according to MIL-DTL-38999 specifications. The main part ACT90MF32PA specification does not explicitly state contact inclusion status.
