ACT90WD18SN Equivalent & Substitute Parts

Part Overview

The ACT90WD18SN is an 18-position circular connector receptacle with female sockets manufactured by TE Connectivity Deutsch Connectors. This component is designed for panel mount applications requiring crimp termination in aerospace and military environments. The part is discontinued at DiGi Electronics, necessitating identification of functionally equivalent alternatives that maintain electrical and mechanical compatibility with existing system designs.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ACT90WD18SN is based on strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Connector type: Receptacle with female sockets
• Position count: 18 positions
• Shell size classification: 15-18
• 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

The CTVPS00RF-15-18JN from Amphenol Aerospace Operations satisfies all mandatory matching parameters and is therefore classified as a direct substitute. Both connectors share identical mechanical interfaces, electrical contact configurations, and environmental sealing characteristics required for aerospace and military applications.

Parameter Comparison

Engineering Selection Recommendations

ACT90WD18SN Status: Discontinued at DiGi Electronics. RoHS non-compliant. Current inventory: 924 pieces available.

CTVPS00RF-15-18JN Status: Active product line. ROHS3 compliant. Current inventory: 778 pieces available.

For new system designs and procurement activities, the CTVPS00RF-15-18JN is the appropriate selection. This substitute maintains full mechanical and electrical compatibility while offering extended operating temperature capability (-65°C to 200°C versus -175°C) and current RoHS3 compliance status. The substitute part is actively manufactured and supported by Amphenol Aerospace Operations.

For legacy system maintenance where the ACT90WD18SN is specified in original documentation, the CTVPS00RF-15-18JN provides direct functional equivalence. Both connectors conform to MIL-DTL-38999 Series III specifications and share identical mating interfaces, pin configurations, and environmental sealing characteristics.

Frequently Asked Questions (FAQ)

Q: Can the CTVPS00RF-15-18JN be used as a direct replacement for the ACT90WD18SN in existing assemblies?

A: Yes. Both connectors are 18-position receptacles with female sockets, identical shell sizes (15-18), panel mount flanges, threaded fastening, and gold-plated contacts. They conform to the same MIL-DTL-38999 Series III standard and share identical mating interfaces.

Q: What are the differences between these two connectors?

A: The primary differences are: (1) Shell finish—ACT90WD18SN uses Olive Drab Cadmium; CTVPS00RF-15-18JN uses Electroless Nickel. (2) Operating temperature upper limit—ACT90WD18SN rated to 175°C; CTVPS00RF-15-18JN rated to 200°C. (3) Contact finish thickness—ACT90WD18SN has 50.0µin plating; CTVPS00RF-15-18JN has 100.0µin plating. (4) RoHS compliance—ACT90WD18SN is non-compliant; CTVPS00RF-15-18JN is ROHS3 compliant. (5) Product status—ACT90WD18SN is discontinued; CTVPS00RF-15-18JN is active.

Q: Are there any compatibility concerns with the different shell finishes?

A: No. Both shell finishes (Olive Drab Cadmium and Electroless Nickel) provide equivalent environmental protection and corrosion resistance for aerospace and military applications. The finish difference does not affect electrical or mechanical interface compatibility.

Q: Does the thicker gold plating on the CTVPS00RF-15-18JN affect compatibility?

A: No. The increased contact finish thickness (100.0µin versus 50.0µin) on the CTVPS00RF-15-18JN provides enhanced durability and wear resistance without affecting mating interface dimensions or electrical performance.

Q: Can the ACT90WD18SN be used in new designs?

A: The ACT90WD18SN is discontinued and RoHS non-compliant. New designs should specify the CTVPS00RF-15-18JN, which is actively manufactured, RoHS3 compliant, and provides superior operating temperature range and contact durability.

Q: What is the current availability of these parts?

A: ACT90WD18SN: 924 pieces in stock (discontinued). CTVPS00RF-15-18JN: 778 pieces in stock (active product).

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

A: Yes. Both connectors are designed for aerospace and military environments. The CTVPS00RF-15-18JN additionally supports marine applications. Both conform to MIL-DTL-38999 Series III specifications and carry EAR99 export classification.
