ACT90MD19PN Equivalent & Substitute Parts

Part Overview

The ACT90MD19PN is a 19-position circular connector receptacle with male pins manufactured by TE Connectivity Deutsch Connectors. This connector is designed for aerospace and military applications and conforms to MIL-DTL-38999 Series III specifications. The part is discontinued at DiGi Electronics, making equivalent substitute parts necessary for ongoing procurement and system maintenance. The connector features crimp termination, panel mount flange configuration, and shielded construction with gold-plated mating contacts.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ACT90MD19PN are qualified based on the following critical parameters that must align with the original specification:

Core Compatibility Parameters:

• Connector type (Receptacle, Male Pins)
• Number of positions (19)
• Shell size classification (15-19)
• Mounting configuration (Panel Mount with Flange)
• Termination method (Crimp)
• Fastening mechanism (Threaded)
• Shielding requirement (Shielded)
• Contact finish (Gold plating on mating surfaces)
• MIL-DTL-38999 Series III compliance

Allowable Variations:

• Shell finish (Nickel, Olive Drab Cadmium, or Electroless Nickel)
• Operating temperature range (provided the range encompasses or matches the application requirement)
• Contact finish thickness (50.0µin to 100.0µin)
• Manufacturer (TE Connectivity Deutsch Connectors or Amphenol Aerospace Operations)
• RoHS compliance status (non-compliant or ROHS3 compliant)

The two substitute parts listed below satisfy all core compatibility parameters and are functionally interchangeable with the ACT90MD19PN in MIL-DTL-38999 Series III applications.

Parameter Comparison

Engineering Selection Recommendations

CTVPS00RF-15-19HN (Amphenol Aerospace Operations) is the primary substitute for the ACT90MD19PN. This part maintains full electrical and mechanical compatibility with identical operating temperature range (-65°C ~ 200°C), matching the original specification. The CTVPS00RF-15-19HN is currently active in production and offers ROHS3 compliance, providing regulatory advantage for new designs and long-term procurement. The electroless nickel shell finish and increased contact finish thickness (100.0µin) provide enhanced corrosion resistance compared to the original part.

CTVP00RW-15-19HN (Amphenol Aerospace Operations) serves as a secondary substitute. This part is functionally equivalent in all core parameters but operates at a reduced maximum temperature of -65°C ~ 175°C. Selection of this part is appropriate only when the application environment does not exceed 175°C. The olive drab cadmium shell finish provides distinctive visual identification and enhanced environmental protection in specific military applications. This part is currently active in production.

Both substitute parts are manufactured by Amphenol Aerospace Operations under the MIL-DTL-38999 Series III specification and are available in active inventory, ensuring reliable procurement for replacement and new applications.

Frequently Asked Questions (FAQ)

Q: Can CTVP00RW-15-19HN replace ACT90MD19PN in all applications?

A: CTVP00RW-15-19HN is functionally equivalent for applications with maximum operating temperatures up to 175°C. If the application requires operation above 175°C up to 200°C, CTVPS00RF-15-19HN must be used instead.

Q: What is the difference between the two Amphenol substitute parts?

A: The primary differences are shell finish (Olive Drab Cadmium versus Electroless Nickel), maximum operating temperature (175°C versus 200°C), and RoHS compliance status (non-compliant versus ROHS3 compliant). Both parts are electrically and mechanically identical in all other parameters.

Q: Are the substitute parts pin-compatible with the original ACT90MD19PN?

A: Yes. Both substitute parts are 19-position receptacles with male pins, identical shell size classification (15-19), and matching crimp termination. They are directly compatible with existing mating connectors and cable assemblies designed for the ACT90MD19PN.

Q: Does the increased contact finish thickness affect performance?

A: The contact finish thickness increase from 50.0µin to 100.0µin on the substitute parts provides enhanced durability and corrosion resistance without affecting electrical performance. Both thicknesses meet MIL-DTL-38999 Series III requirements.

Q: Which substitute part should be selected for new designs?

A: CTVPS00RF-15-19HN is recommended for new designs due to ROHS3 compliance and full temperature range compatibility (-65°C ~ 200°C). This part ensures regulatory compliance and eliminates the need for future redesign if RoHS requirements become mandatory.

Q: Are there any packaging differences between the original and substitute parts?

A: The original ACT90MD19PN was packaged in standard format. Both substitute parts are supplied in bulk packaging. Verify packaging requirements with your procurement specification before ordering.

Q: Can these parts be used interchangeably in existing assemblies?

A: Yes, provided the application temperature range does not exceed the rated maximum of the selected substitute part. The mechanical interface, pin configuration, and electrical characteristics are identical across all three parts.
