Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ACT90MJ29PN are identified based on strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Connector type: Receptacle with male pins
• Number of positions: 29
• Shell size insert range: 25-29
• Series compliance: MIL-DTL-38999 Series III
• Mounting configuration: Panel mount with flange
• Termination method: Crimp
• Fastening mechanism: Threaded
• Shielding: Shielded construction
• Contact finish: Gold plating on mating surfaces
• Primary material: Composite shell and thermoplastic insert
• Contact material: Copper alloy

Allowable Variations:

• Shell finish (Nickel, Olive Drab Cadmium, or Electroless Nickel)
• Contact finish thickness (50.0µin to 100.0µin)
• Operating temperature upper limit (175°C to 200°C)
• RoHS compliance status
• Manufacturer identity within aerospace connector industry

Substitute parts must maintain compatibility with existing mating connectors and cable assemblies designed for the ACT90MJ29PN interface.

Engineering Selection Recommendations

CTVPS00RF-25-29HN (Primary Substitute)

The CTVPS00RF-25-29HN from Amphenol Aerospace Operations is the primary equivalent substitute for the ACT90MJ29PN. 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-25-29HN is currently in active production status with 1,064 units in stock. The part achieves ROHS3 compliance, providing regulatory advantage for new system designs and procurement cycles. The electroless nickel shell finish and increased contact finish thickness (100.0µin versus 50.0µin) provide enhanced durability and corrosion resistance compared to the original part.

CTVP00RW-25-29HN (Secondary Substitute)

The CTVP00RW-25-29HN from Amphenol Aerospace Operations is a functional equivalent with one operational constraint. This part is fully compatible across mechanical and electrical parameters but operates to a maximum temperature of 175°C, compared to the 200°C upper limit of the ACT90MJ29PN. The CTVP00RW-25-29HN is suitable for applications where the operating temperature does not exceed 175°C. This part is currently in active production with 694 units in stock. The olive drab cadmium shell finish provides distinct visual identification and enhanced environmental protection for military and aerospace applications.

Compliance Considerations

For new system designs subject to RoHS3 requirements, the CTVPS00RF-25-29HN is the appropriate selection. For legacy system support and retrofit applications where RoHS compliance is not mandated, both Amphenol substitutes provide equivalent functionality to the discontinued ACT90MJ29PN.

Frequently Asked Questions (FAQ)

Q: Can the CTVPS00RF-25-29HN be used as a direct replacement for the ACT90MJ29PN in existing assemblies?

A: Yes. The CTVPS00RF-25-29HN maintains full mechanical and electrical compatibility with the ACT90MJ29PN. The connector interfaces, pin configurations, mounting dimensions, and termination methods are identical. The electroless nickel finish and increased contact plating thickness provide equivalent or superior performance characteristics.

Q: What is the difference between the CTVP00RW-25-29HN and CTVPS00RF-25-29HN?

A: Both parts are functionally equivalent with two primary differences. The CTVP00RW-25-29HN operates to a maximum temperature of 175°C, while the CTVPS00RF-25-29HN operates to 200°C. The CTVP00RW-25-29HN features an olive drab cadmium shell finish, while the CTVPS00RF-25-29HN features electroless nickel. The CTVPS00RF-25-29HN is ROHS3 compliant, while the CTVP00RW-25-29HN is not.

Q: Are there any packaging differences between the substitute parts and the original ACT90MJ29PN?

A: The CTVPS00RF-25-29HN is supplied in bulk packaging. The original ACT90MJ29PN packaging specification was not provided in the technical data. Confirm packaging requirements with procurement specifications for your application.

Q: Which substitute part should be selected for new aerospace system designs?

A: The CTVPS00RF-25-29HN is the recommended selection for new designs. This part is in active production, ROHS3 compliant, and maintains the full -65°C to 200°C operating temperature range of the original part. The increased contact finish thickness provides enhanced reliability for long-term aerospace applications.

Q: Can the CTVP00RW-25-29HN be used in applications requiring operation at 200°C?

A: No. The CTVP00RW-25-29HN is rated to a maximum operating temperature of 175°C. Applications requiring operation at temperatures between 175°C and 200°C must use the CTVPS00RF-25-29HN.

Q: Are all three connectors (ACT90MJ29PN, CTVP00RW-25-29HN, and CTVPS00RF-25-29HN) compatible with the same mating plugs?

A: Yes. All three connectors comply with MIL-DTL-38999 Series III specifications for 29-position circular connectors. They are mechanically and electrically compatible with standard MIL-DTL-38999 Series III mating plugs designed for 29-position receptacles.

Q: What is the significance of the contact finish thickness difference between the parts?

A: The ACT90MJ29PN features 50.0µin (1.27µm) gold plating on mating contacts, while both Amphenol substitutes feature 100.0µin (2.54µm) plating. The increased thickness provides enhanced wear resistance and extended service life in high-cycle mating applications.
