Key Parameters

Substitute Part Grouping Explanation

Substitution of the ACT90WD19SN is determined by strict adherence to the following parameters:

Critical Matching Parameters:

• Connector type: Receptacle with female sockets
• Position count: 19 positions
• Shell size insert designation: 15-19
• Mounting configuration: Panel mount with flange
• Termination method: Crimp
• Fastening mechanism: Threaded
• Shielding requirement: Shielded construction
• Contact finish: Gold plating on mating surfaces
• Specification compliance: MIL-DTL-38999 Series III

Allowable Variations:

• Shell finish material (Olive Drab Cadmium or Electroless Nickel)
• Contact finish thickness (50.0µin to 100.0µin)
• Operating temperature upper limit (175°C to 200°C)
• Current rating specification (when provided)
• RoHS compliance status
• Manufacturer (TE Connectivity, Amphenol Aerospace Operations)

Two substitute parts meet these criteria and are identified as direct equivalents for the ACT90WD19SN.

Parameter Comparison

Engineering Selection Recommendations

CTVP00RW-15-19JN Selection Criteria:

This substitute maintains identical operating temperature range (-65°C to 175°C) and shell finish (Olive Drab Cadmium) as the original ACT90WD19SN. The part is currently active in production and available in higher inventory quantities (1021 pieces). The contact finish thickness is increased to 100.0µin (2.54µm), providing enhanced durability compared to the original 50.0µin specification. This part is RoHS non-compliant, matching the compliance status of the original component. Selection of this substitute is appropriate for applications requiring direct functional equivalence with identical environmental specifications.

CTVPS00RF-15-19JN Selection Criteria:

This substitute offers an extended operating temperature range (-65°C to 200°C), providing additional thermal margin for high-temperature applications. The part features Electroless Nickel shell finish instead of Olive Drab Cadmium, offering alternative corrosion resistance characteristics. Critically, this part is RoHS3 compliant, making it suitable for applications subject to RoHS regulatory requirements. The contact finish thickness is 100.0µin (2.54µm), matching the enhanced durability of the first substitute. This part is available in the highest inventory quantity (1224 pieces) and is actively produced. Selection of this substitute is appropriate for applications requiring RoHS compliance or extended thermal operating range.

Both substitutes are qualified to MIL-DTL-38999 Series III specification and maintain all critical mechanical and electrical parameters required for direct replacement in aerospace and military applications.

Frequently Asked Questions (FAQ)

Q: Can CTVP00RW-15-19JN and CTVPS00RF-15-19JN be used interchangeably with ACT90WD19SN?

A: Both substitutes are mechanically and electrically compatible with the ACT90WD19SN. They share identical connector type, position count, shell size, mounting configuration, termination method, and MIL-DTL-38999 Series III qualification. Selection between them depends on specific application requirements regarding RoHS compliance and operating temperature range.

Q: What is the difference in shell finish between the substitutes?

A: The ACT90WD19SN and CTVP00RW-15-19JN feature Olive Drab Cadmium shell finish. The CTVPS00RF-15-19JN features Electroless Nickel shell finish. Both finishes provide environment-resistant protection; selection depends on application-specific corrosion resistance requirements and compatibility with existing connector populations.

Q: Does the increased contact finish thickness affect compatibility?

A: The increased contact finish thickness (100.0µin versus 50.0µin on the original) does not affect mechanical or electrical compatibility. The thicker gold plating on the mating surfaces of both substitutes provides enhanced durability and contact reliability without altering connector dimensions or mating characteristics.

Q: Which substitute should be selected for RoHS-regulated applications?

A: The CTVPS00RF-15-19JN is RoHS3 compliant and is the appropriate selection for applications subject to RoHS regulatory requirements. The ACT90WD19SN and CTVP00RW-15-19JN are both RoHS non-compliant.

Q: Are there temperature limitations when selecting a substitute?

A: The ACT90WD19SN and CTVP00RW-15-19JN are rated for -65°C to 175°C operation. The CTVPS00RF-15-19JN is rated for -65°C to 200°C operation. For applications requiring operation above 175°C, the CTVPS00RF-15-19JN is the appropriate selection.

Q: What is the packaging difference between substitutes?

A: The CTVP00RW-15-19JN packaging is not specified in available data. The CTVPS00RF-15-19JN is supplied in bulk packaging. Packaging differences do not affect connector functionality or compatibility.

Q: Is current rating a factor in substitute selection?

A: The ACT90WD19SN specifies a 7.5A current rating. Current ratings are not specified for either substitute in available data. For applications with specific current requirements, contact the manufacturer for current rating specifications of the substitute parts.

Q: Can these connectors be used in aviation and marine applications?

A: Yes. Both substitutes are qualified for aviation, marine, and military applications. The original ACT90WD19SN is qualified for aerospace and military applications. All three parts meet MIL-DTL-38999 Series III specification requirements for these application environments.
