Key Parameters

Substitute Part Grouping Explanation

Substitution of the ACT90WH55SB is determined by strict equivalence across the following critical parameters:

Primary Substitution Criteria:

• Connector type: Receptacle with female sockets
• Position count: 55 positions
• Shell size designation: 23-55
• Series compliance: MIL-DTL-38999 Series III
• Mounting configuration: Panel mount with flange
• Termination method: Crimp
• Fastening mechanism: Threaded
• Orientation code: B
• Shell material and finish: Composite with Olive Drab Cadmium
• Contact finish: Gold-plated
• Shielding: Shielded configuration
• Operating temperature range: -65°C ~ 175°C
• Contact material: Copper alloy
• Insert material: Thermoplastic

The substitute parts listed maintain these core parameters, ensuring mechanical and electrical compatibility with systems designed for the ACT90WH55SB. Variations in contact finish thickness and current rating specifications do not preclude substitution where the primary parameters align.

Parameter Comparison

Engineering Selection Recommendations

CTVP00RW-23-55SB (Amphenol Aerospace Operations)

This part is the primary substitute for the ACT90WH55SB. Both connectors maintain identical specifications across all critical parameters: 55-position configuration, MIL-DTL-38999 Series III compliance, panel mount flange design, crimp termination, threaded fastening, composite shell with Olive Drab Cadmium finish, gold-plated copper alloy contacts, and identical operating temperature range. The CTVP00RW-23-55SB is currently active in production, ensuring availability and supply chain continuity. Contact finish thickness matches the original specification at 50.0µin (1.27µm). This part is suitable for direct replacement in aerospace and military applications.

CTVP00RW-23-55JB (Amphenol Aerospace Operations)

This part maintains all core mechanical and electrical parameters equivalent to the ACT90WH55SB with one specification variance: contact finish thickness is 100.0µin (2.54µm) compared to the original 50.0µin (1.27µm). This increased gold plating thickness provides enhanced contact durability and corrosion resistance. The part is currently active in production and complies with MIL-DTL-38999 Series III. This connector is suitable for applications where extended contact life and enhanced environmental resistance are beneficial.

CTVP00RW-23-55JB-LC (Amphenol Aerospace Operations)

This part is a receptacle housing assembly without integrated contacts. It is supplied as a housing shell only and is not a direct functional substitute for the complete ACT90WH55SB connector. This part is applicable only in scenarios where housing replacement is required separately from contact assembly, or where custom contact configurations are specified. The housing maintains identical mechanical parameters and MIL-DTL-38999 Series III compliance.

All substitute parts are RoHS non-compliant and carry MSL rating of 1 (Unlimited), matching the original part's compliance profile.

Frequently Asked Questions (FAQ)

Q: Can CTVP00RW-23-55SB be used as a direct replacement for ACT90WH55SB?

A: Yes. The CTVP00RW-23-55SB maintains identical specifications across all critical parameters including connector type, position count, shell size, series compliance, mounting configuration, termination method, fastening type, shell material and finish, contact finish, shielding, operating temperature range, and contact material. This part is suitable for direct substitution in existing applications.

Q: What is the difference between CTVP00RW-23-55SB and CTVP00RW-23-55JB?

A: Both parts are functionally equivalent 55-position receptacles with female sockets. The primary difference is contact finish thickness: CTVP00RW-23-55SB has 50.0µin (1.27µm) gold plating, matching the original ACT90WH55SB specification, while CTVP00RW-23-55JB has 100.0µin (2.54µm) gold plating. The thicker plating on the CTVP00RW-23-55JB provides increased contact durability.

Q: Is CTVP00RW-23-55JB-LC a suitable replacement for ACT90WH55SB?

A: No. The CTVP00RW-23-55JB-LC is a housing assembly only and does not include integrated contacts. It is not a complete connector and cannot function as a direct replacement. This part is applicable only when housing replacement is required as a separate component.

Q: Are all substitute parts MIL-DTL-38999 Series III compliant?

A: Yes. All listed substitute parts comply with MIL-DTL-38999 Series III specification, ensuring compatibility with military and aerospace system requirements.

Q: What is the current availability status of substitute parts?

A: CTVP00RW-23-55SB, CTVP00RW-23-55JB, and CTVP00RW-23-55JB-LC are all currently active products from Amphenol Aerospace Operations. The original ACT90WH55SB is discontinued at DiGi Electronics.

Q: Do the substitute parts maintain the same operating temperature range?

A: Yes. All substitute parts operate across the identical temperature range of -65°C to 175°C, matching the ACT90WH55SB specification.

Q: Are there differences in RoHS compliance between the main part and substitutes?

A: No. The ACT90WH55SB and all listed substitute parts are RoHS non-compliant with identical MSL rating of 1 (Unlimited).

Q: What packaging options are available for substitute parts?

A: CTVP00RW-23-55SB and CTVP00RW-23-55JB-LC are supplied in bulk packaging. CTVP00RW-23-55JB packaging information is not specified in the provided data.

Q: Can the substitute parts be used in aviation and marine applications?

A: Yes. The Amphenol substitute parts are rated for aviation, marine, and military applications, expanding the application scope beyond the original ACT90WH55SB which is specified for aerospace and military use only.
