Key Parameters

Substitute Part Grouping Explanation

Substitution of the ACT90WG35PN is determined by strict equivalence across the following critical parameters:

Primary Matching Criteria:

• Connector type: Receptacle with male pins
• Position count: 79 positions
• Shell size: 21-35 insert designation
• Series compliance: MIL-DTL-38999 Series III
• Mounting configuration: Panel mount with flange
• Termination method: Crimp
• Fastening: Threaded
• Contact finish: Gold plating on mating surfaces
• Shielding: Shielded configuration
• Environmental rating: Environment resistant

Secondary Compatibility Factors:

• Operating temperature range: -65°C minimum to 175°C minimum
• Ingress protection classification
• Contact material: Copper alloy base
• Orientation designation (Normal or equivalent)

Substitute parts must satisfy all primary matching criteria. Variations in shell material composition, contact finish thickness, or manufacturer-specific design features do not preclude substitution when all primary parameters align.

Parameter Comparison

Engineering Selection Recommendations

CTVP00RW-21-35HN (Amphenol Aerospace Operations)

This substitute provides the closest functional equivalence to the ACT90WG35PN. The CTVP00RW-21-35HN matches all primary parameters including 79-position configuration, 21-35 shell size, MIL-DTL-38999 Series III compliance, panel mount flange, crimp termination, and normal orientation. Operating temperature range (-65°C ~ 175°C) is identical. The part is currently active in production with 1024 units in stock. Contact finish thickness is increased to 100.0µin (2.54µm), providing enhanced durability compared to the original 50.0µin specification.

CTVP00RW-21-35HA (Amphenol Aerospace Operations)

This alternative meets all primary substitution criteria with identical electrical and mechanical specifications to the CTVP00RW-21-35HN. The primary distinction is orientation designation (A versus N). This part is active with 818 units available. Selection between CTVP00RW-21-35HA and CTVP00RW-21-35HN depends on specific orientation requirements for the application.

D38999/20FG35PN (Conesys)

This substitute satisfies all primary matching criteria and is ROHS3 compliant, addressing environmental regulatory requirements not met by the original ACT90WG35PN. The D38999/20FG35PN features an extended operating temperature range (-65°C ~ 200°C), providing additional thermal margin. Shell material differs (aluminum with electroless nickel finish versus composite), and contact finish thickness matches the original specification at 50.0µin (1.27µm). The part is active with 969 units in stock.

CTVP00RW-21-35P (Amphenol Aerospace Operations)

Limited technical data is provided for this part number. Documented parameters confirm 79-position configuration, 21-35 shell size, panel mount flange, crimp termination, and MIL-DTL-38999 Series III compliance. This part is active with 922 units available. Complete specification verification is required before selection.

Frequently Asked Questions (FAQ)

Q: Can the CTVP00RW-21-35HN directly replace the ACT90WG35PN in existing assemblies?

A: The CTVP00RW-21-35HN meets all primary electrical and mechanical parameters required for substitution. Both connectors are 79-position receptacles with male pins, 21-35 shell size, MIL-DTL-38999 Series III compliance, panel mount flange configuration, crimp termination, and threaded fastening. Operating temperature ranges are identical. Physical compatibility with existing panel cutouts and mating plugs is confirmed by specification alignment.

Q: What is the significance of the contact finish thickness difference between the ACT90WG35PN (50.0µin) and CTVP00RW-21-35HN (100.0µin)?

A: Contact finish thickness affects durability and wear resistance during mating cycles. The increased thickness of 100.0µin (2.54µm) on the Amphenol substitute provides extended service life and enhanced protection against contact degradation. This represents an improvement over the original specification and does not compromise electrical performance or mechanical compatibility.

Q: Why is the D38999/20FG35PN listed as ROHS3 compliant while the original ACT90WG35PN is not?

A: RoHS compliance status reflects the materials and manufacturing processes used in connector construction. The D38999/20FG35PN meets ROHS3 environmental standards, making it suitable for applications with regulatory requirements restricting hazardous substances. The original ACT90WG35PN does not meet these standards. Selection between compliant and non-compliant alternatives depends on application regulatory requirements.

Q: What is the difference between orientation designations N (Normal) and A in the substitute parts?

A: Orientation designation indicates the rotational position of the connector insert relative to the shell. N (Normal) and A represent different angular alignments. The ACT90WG35PN specifies N orientation. The CTVP00RW-21-35HN also specifies N orientation, providing direct compatibility. The CTVP00RW-21-35HA specifies A orientation and is suitable only if the application permits this alternative alignment.

Q: Are all substitute parts available in the same packaging as the original ACT90WG35PN?

A: Packaging specifications vary among substitutes. The ACT90WG35PN packaging is not specified in available data. The D38999/20FG35PN is supplied in box packaging, while the CTVP00RW-21-35P is supplied in bulk packaging. Packaging differences do not affect connector functionality but may impact receiving, storage, and handling procedures. Verify packaging requirements with procurement specifications.

Q: Can the ACT90WG35PN be used interchangeably with the CTVP00RW-21-35P without additional verification?

A: The CTVP00RW-21-35P meets primary substitution criteria for 79-position configuration, 21-35 shell size, panel mount flange, crimp termination, and MIL-DTL-38999 Series III compliance. However, limited technical documentation is available for this part number. Complete specification verification including operating temperature range, current rating, and contact finish specifications is required before confirming interchangeability.

Q: What inventory considerations should guide substitute part selection?

A: All substitute parts are currently in stock with comparable availability: CTVP00RW-21-35HN (1024 units), D38999/20FG35PN (969 units), CTVP00RW-21-35P (922 units), and CTVP00RW-21-35HA (818 units). Inventory levels support production requirements for most applications. Selection should prioritize functional equivalence and compliance requirements over inventory quantity, as all alternatives demonstrate adequate stock levels.
