ACT90MG16PN Equivalent & Substitute Parts

Part Overview

The ACT90MG16PN is a 16-position circular connector receptacle with male pins, manufactured by TE Connectivity Deutsch Connectors. This component is designed for aerospace and military applications requiring shielded, crimp-terminated connections with gold-plated mating surfaces. The part is discontinued at DiGi Electronics, necessitating identification of functionally equivalent alternatives that maintain compliance with MIL-DTL-38999 Series III specifications and operational requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ACT90MG16PN is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Connector type: Receptacle with male pins
• Number of positions: 16
• Shell size - insert designation: 21-16
• Mounting configuration: Panel mount with flange
• Termination method: Crimp
• Fastening mechanism: Threaded
• Shielding requirement: Shielded
• Contact finish: Gold plating on mating surfaces
• Series compliance: MIL-DTL-38999 Series III

Allowable Variations:

• Shell finish color and plating composition
• Contact finish thickness (within gold plating specification)
• Operating temperature upper limit (provided minimum -65°C is maintained)
• Current rating (provided specification is met or exceeded)
• Manufacturer identity (alternative qualified suppliers)

The CTVP00RW-21-16HN from Amphenol Aerospace Operations satisfies all mandatory matching parameters and qualifies as a direct substitute.

Parameter Comparison

Engineering Selection Recommendations

The CTVP00RW-21-16HN is a qualified substitute for the ACT90MG16PN based on the following engineering criteria:

Functional Equivalence: Both connectors meet MIL-DTL-38999 Series III specifications with identical mechanical and electrical interface characteristics. The 16-position, 21-16 shell size configuration, crimp termination, threaded fastening, and shielded design are identical across both parts.

Availability and Product Status: The ACT90MG16PN is discontinued at DiGi Electronics. The CTVP00RW-21-16HN is currently active in production with 886 units in stock, providing immediate availability for new designs and replacement applications.

Compliance Considerations: Both parts carry identical RoHS non-compliant status and EAR99 ECCN classification. Both are rated MSL 1 (Unlimited moisture sensitivity level). No compliance advantage exists between the two options.

Operating Temperature Limitation: The CTVP00RW-21-16HN operates to 175°C maximum, compared to 200°C for the ACT90MG16PN. Applications requiring operation above 175°C cannot use the Amphenol substitute.

Contact Finish Enhancement: The CTVP00RW-21-16HN provides 100.0µin gold plating thickness versus 50.0µin on the original part, offering enhanced contact durability and wear resistance.

Shell Finish Difference: The Amphenol part features Olive Drab Cadmium finish versus Nickel finish on the TE Connectivity part. This cosmetic and corrosion-resistance difference does not affect electrical or mechanical function in sealed panel-mount applications.

Frequently Asked Questions (FAQ)

Q: Can the CTVP00RW-21-16HN directly replace the ACT90MG16PN in existing designs?

A: Yes, for applications operating at or below 175°C. Both connectors share identical mating interfaces, pin configurations, mounting geometry, and electrical characteristics. The substitute maintains full mechanical and electrical compatibility.

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

A: Shell finish affects corrosion resistance and environmental durability. Olive Drab Cadmium provides enhanced corrosion protection in harsh environments. For sealed panel-mount applications, both finishes provide adequate environmental resistance. Selection depends on specific environmental exposure requirements.

Q: Why does the Amphenol part have thicker gold plating?

A: The CTVP00RW-21-16HN specifies 100.0µin gold plating compared to 50.0µin on the ACT90MG16PN. Thicker plating extends contact life and improves wear resistance during mating cycles. This represents an enhancement over the original specification.

Q: Are there current rating differences between these parts?

A: The ACT90MG16PN is rated at 13A. The CTVP00RW-21-16HN current rating is not specified in available documentation. Both parts are designed for identical shell sizes and pin configurations, suggesting equivalent current-carrying capacity. Verify current requirements against application specifications.

Q: What is the maximum operating temperature difference, and does it matter?

A: The ACT90MG16PN operates to 200°C; the CTVP00RW-21-16HN to 175°C. This 25°C difference is significant only for high-temperature applications. If your design operates below 175°C, this difference is not a limiting factor.

Q: Are both parts compliant with MIL-DTL-38999 Series III?

A: Yes. The ACT90MG16PN is designated Series III, ACT. The CTVP00RW-21-16HN is Series III, Tri-Start™ TV. Both meet the same military specification standard for 16-position circular connectors.

Q: What is the inventory status for each part?

A: The ACT90MG16PN is discontinued with 1025 units in stock. The CTVP00RW-21-16HN is active production with 886 units in stock, providing ongoing availability.
