ACT90WD18PN Equivalent & Substitute Parts

Part Overview

The ACT90WD18PN is an 18-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 contacts. The part is discontinued at DiGi Electronics, necessitating identification of functionally equivalent alternatives that maintain compliance with MIL-DTL-38999 Series III specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ACT90WD18PN is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Connector type: Receptacle with male pins
• Number of positions: 18
• Shell size insert range: 15-18
• Series compliance: MIL-DTL-38999 Series III
• Mounting configuration: Panel mount with flange
• Termination method: Crimp
• Fastening mechanism: Threaded
• Shielding requirement: Shielded
• Contact finish: Gold-plated mating surfaces
• Ingress protection: Environment resistant

Allowable Variations:

• Shell finish material (Olive Drab Cadmium vs. Electroless Nickel)
• Contact finish thickness (50.0µin vs. 100.0µin)
• Operating temperature upper limit (175°C vs. 200°C)
• RoHS compliance status
• Manufacturer identity (TE Connectivity vs. Amphenol Aerospace Operations)

The substitute parts CTVP00RW-15-18HN and CTVPS00RF-15-18HN satisfy all mandatory matching parameters and are therefore functionally equivalent for direct substitution.

Parameter Comparison

Engineering Selection Recommendations

CTVP00RW-15-18HN Selection Criteria:

This substitute maintains full functional equivalence to the ACT90WD18PN across all critical electrical and mechanical parameters. The part is currently active in production with 861 units in stock. The contact finish thickness of 100.0µin provides enhanced durability compared to the original 50.0µin specification. Shell finish remains Olive Drab Cadmium, preserving visual and environmental consistency with the original design. This option is suitable for applications where RoHS non-compliance is acceptable and existing design specifications do not mandate RoHS3 compliance.

CTVPS00RF-15-18HN Selection Criteria:

This substitute provides full functional equivalence with the additional advantage of ROHS3 compliance, addressing regulatory requirements for new designs or procurement mandates. The electroless nickel shell finish differs from the original Olive Drab Cadmium, resulting in a silver appearance. The operating temperature upper limit extends to 200°C, providing enhanced thermal margin beyond the original 175°C specification. Contact finish thickness of 100.0µin matches the CTVP00RW-15-18HN variant. This option is preferred for applications requiring RoHS3 compliance or extended temperature operation. Inventory availability is 1032 units.

Both substitute parts are manufactured by Amphenol Aerospace Operations under the MIL-DTL-38999 Series III Tri-Start™ TV series designation and maintain full compatibility with existing panel mount installations and crimp termination processes.

Frequently Asked Questions (FAQ)

Q: Can CTVP00RW-15-18HN or CTVPS00RF-15-18HN be used as direct replacements for ACT90WD18PN?

A: Yes. Both substitute parts maintain identical connector type, position count, shell size, series compliance, mounting configuration, termination method, and shielding characteristics. All three connectors are MIL-DTL-38999 Series III compliant 18-position receptacles with male pins, panel mount flanges, threaded fastening, and gold-plated contacts. Direct substitution is functionally valid.

Q: What is the difference between CTVP00RW-15-18HN and CTVPS00RF-15-18HN?

A: The primary differences are shell finish material, color, operating temperature range, and RoHS compliance status. CTVP00RW-15-18HN features Olive Drab Cadmium finish with -65°C to 175°C operating range and RoHS non-compliance. CTVPS00RF-15-18HN features Electroless Nickel finish with -65°C to 200°C operating range and ROHS3 compliance. Both have identical contact finish thickness of 100.0µin and equivalent electrical performance.

Q: Does the contact finish thickness difference affect compatibility?

A: No. The ACT90WD18PN specifies 50.0µin contact finish thickness, while both substitutes provide 100.0µin thickness. Increased gold plating thickness enhances contact durability and corrosion resistance without affecting electrical or mechanical compatibility. This represents an improvement over the original specification.

Q: Are there packaging differences between these parts?

A: The ACT90WD18PN packaging is listed as unspecified. Both substitute parts are supplied in bulk packaging. This does not affect functional compatibility or installation procedures.

Q: Which substitute should be selected for new designs?

A: CTVPS00RF-15-18HN is recommended for new designs due to ROHS3 compliance, which aligns with current regulatory requirements and procurement standards. The extended operating temperature range to 200°C provides additional design margin. CTVP00RW-15-18HN is suitable for legacy system maintenance or applications where RoHS compliance is not mandated.

Q: Are both substitutes available in adequate quantities?

A: Yes. CTVP00RW-15-18HN has 861 units in stock, and CTVPS00RF-15-18HN has 1032 units in stock, providing sufficient inventory for production and maintenance requirements.

Q: Do the shell finish differences affect environmental performance?

A: Both shell finishes provide environment-resistant protection suitable for aerospace and military applications. Olive Drab Cadmium and Electroless Nickel finishes are both qualified under MIL-DTL-38999 Series III specifications. Selection should be based on design requirements, regulatory compliance, and visual identification needs.
