ACT90MD19SN Equivalent & Substitute Parts

Part Overview

The ACT90MD19SN is a 19-position circular connector receptacle manufactured by TE Connectivity Deutsch Connectors, designed for aerospace and military applications. This connector features female sockets with crimp termination, gold-plated mating contacts, and operates across a temperature range of -65°C to 200°C. The part is discontinued at DiGi Electronics, necessitating identification of equivalent substitute components that maintain functional and electrical compatibility for system integration and maintenance applications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ACT90MD19SN are qualified based on the following critical parameters that determine functional interchangeability:

Core Compatibility Criteria:

• Connector type: Receptacle with female sockets
• Position count: 19 positions
• Shell size classification: 15-19
• Mounting configuration: Panel mount with flange
• Termination method: Crimp
• Fastening mechanism: Threaded
• Orientation: Normal (N)
• Shell material: Composite construction
• Contact finish: Gold plating on mating surfaces
• Shielding: Shielded design
• Contact material: Copper alloy
• MIL-DTL-38999 Series III qualification

The substitute parts CTVP00RW-15-19JN and CTVPS00RF-15-19JN satisfy these core parameters, enabling direct substitution in applications requiring 19-position circular connector receptacles with the specified mechanical and electrical characteristics.

Parameter Comparison

Engineering Selection Recommendations

CTVPS00RF-15-19JN is the primary substitute for the ACT90MD19SN. This part maintains full mechanical and electrical compatibility across all critical parameters, including the complete operating temperature range of -65°C to 200°C. The CTVPS00RF-15-19JN is currently active in production, ensuring supply chain availability. Additionally, this part achieves ROHS3 compliance, providing environmental regulatory advantage for new system designs and long-term procurement strategies.

CTVP00RW-15-19JN serves as an alternative substitute with equivalent mechanical compatibility. This part is also active in production. The operating temperature range is limited to -65°C to 175°C, which restricts its application in systems requiring the full 200°C upper temperature capability of the original ACT90MD19SN. The shell finish differs, featuring Olive Drab Cadmium plating instead of nickel, and the connector exhibits non-compliant RoHS status.

For applications requiring the complete -65°C to 200°C operating range without environmental compliance constraints, either substitute is functionally equivalent. For new designs or systems with RoHS compliance requirements, CTVPS00RF-15-19JN is the appropriate selection.

Frequently Asked Questions (FAQ)

Q: Can CTVPS00RF-15-19JN directly replace ACT90MD19SN in existing assemblies?

A: Yes. Both connectors share identical mechanical mounting configurations, pin counts, shell sizes, and crimp termination specifications. The connectors are mechanically and electrically interchangeable for panel-mount applications requiring 19-position circular receptacles with female sockets.

Q: What is the significance of the operating temperature difference between CTVP00RW-15-19JN and the original part?

A: The ACT90MD19SN and CTVPS00RF-15-19JN both operate to 200°C. The CTVP00RW-15-19JN is rated to 175°C maximum. Applications requiring sustained operation above 175°C must use either the original part or CTVPS00RF-15-19JN.

Q: Does the contact finish thickness difference affect compatibility?

A: The substitute parts feature 100.0µin (2.54µm) gold plating compared to the original 50.0µin (1.27µm). Both thicknesses meet MIL-DTL-38999 Series III specifications and provide equivalent mating performance and durability.

Q: What is the advantage of CTVPS00RF-15-19JN regarding RoHS compliance?

A: CTVPS00RF-15-19JN achieves ROHS3 compliance, eliminating restricted substances in accordance with current environmental regulations. This qualification is beneficial for procurement in regulated markets and for systems designed to meet modern environmental standards.

Q: Are there inventory considerations when selecting a substitute?

A: CTVPS00RF-15-19JN is available in bulk packaging with 1224 pieces in stock. CTVP00RW-15-19JN is available with 1021 pieces in stock. Both substitutes offer superior availability compared to the discontinued ACT90MD19SN.

Q: Do the shell finish differences between substitutes affect electrical performance?

A: Shell finish variations (Nickel, Olive Drab Cadmium, Electroless Nickel) do not affect electrical performance or signal integrity. These differences are cosmetic and relate to environmental protection and corrosion resistance characteristics.

Q: Which substitute is recommended for new aerospace system designs?

A: CTVPS00RF-15-19JN is recommended for new designs. This part maintains full temperature range compatibility, achieves ROHS3 compliance, and is actively produced by Amphenol Aerospace Operations, ensuring long-term supply chain stability.
