Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ACT90MH55SA are identified based on strict alignment with the following critical parameters:

Electrical Compatibility:

• 55-position configuration
• Crimp termination method
• Shielded design
• Operating temperature range: -65°C ~ 200°C
• Current rating: 7.5A

Mechanical Compatibility:

• Shell size insert: 23-55
• Panel mount configuration with flange
• Threaded fastening type
• Orientation: A
• Composite shell material
• Female socket receptacle type

Qualification & Standards:

• MIL-DTL-38999 Series III compliance

The substitute parts CTVPS00RF-23-55JA-LC and CTVPS00RF-23-55SA-LC, manufactured by Amphenol Aerospace Operations, satisfy all critical parameters. Both are receptacle housings for female sockets with 55 positions, panel mount configuration, threaded fastening, and identical operating temperature specifications. Both maintain MIL-DTL-38999 Series III qualification and shielded design. The primary distinction between substitutes is RoHS compliance status and active product availability.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute Selection:

Both CTVPS00RF-23-55JA-LC and CTVPS00RF-23-55SA-LC are functionally equivalent to the ACT90MH55SA for applications requiring 55-position circular connector receptacles with female sockets, crimp termination, and MIL-DTL-38999 Series III compliance.

Compliance Considerations:

The Amphenol Aerospace Operations substitutes (CTVPS00RF-23-55JA-LC and CTVPS00RF-23-55SA-LC) are ROHS3 compliant, whereas the original ACT90MH55SA is RoHS non-compliant. For programs with RoHS compliance mandates, the Amphenol substitutes satisfy regulatory requirements while maintaining electrical and mechanical compatibility.

Product Availability:

Both substitute parts are classified as active products with current inventory availability (820 Pcs and 740 Pcs respectively), compared to the discontinued status of the original part. This ensures long-term procurement viability for ongoing production and field support.

Mechanical Compatibility:

All three connectors share identical mechanical specifications: 55-position configuration, 23-55 shell size insert, panel mount with flange, threaded fastening, and orientation A. Physical interchangeability is confirmed for panel-mounted applications.

Electrical Compatibility:

Operating temperature range (-65°C ~ 200°C), shielded design, crimp termination, and current rating (7.5A) are consistent across all three parts, confirming electrical performance equivalence.

Frequently Asked Questions (FAQ)

Q: Can CTVPS00RF-23-55JA-LC or CTVPS00RF-23-55SA-LC be used as direct replacements for ACT90MH55SA?

A: Both Amphenol Aerospace Operations parts are mechanically and electrically compatible substitutes. They share identical position count (55), shell size (23-55), mounting configuration (panel mount with flange), termination method (crimp), fastening type (threaded), and operating temperature range (-65°C ~ 200°C). Both maintain MIL-DTL-38999 Series III qualification.

Q: What is the difference between CTVPS00RF-23-55JA-LC and CTVPS00RF-23-55SA-LC?

A: Both parts are functionally equivalent with identical electrical and mechanical specifications. The designation difference (JA versus SA) reflects manufacturer part numbering conventions. Both are active products with current inventory and ROHS3 compliance.

Q: Are the substitute parts RoHS compliant?

A: Yes. Both CTVPS00RF-23-55JA-LC and CTVPS00RF-23-55SA-LC are ROHS3 compliant. The original ACT90MH55SA is RoHS non-compliant. For applications requiring RoHS compliance, the Amphenol substitutes satisfy regulatory requirements.

Q: Do the substitute parts include contacts?

A: No. Both CTVPS00RF-23-55JA-LC and CTVPS00RF-23-55SA-LC are receptacle housings supplied without contacts. Contacts must be procured separately and crimped into the housing.

Q: Are the operating temperature ranges identical?

A: Yes. All three connectors operate across -65°C to 200°C, confirming thermal compatibility for aerospace and military applications.

Q: What is the current rating for these connectors?

A: The ACT90MH55SA is rated for 7.5A. The substitute parts maintain this current rating specification.

Q: Are these connectors shielded?

A: Yes. All three connectors feature shielded design for electromagnetic interference protection.

Q: What is the moisture sensitivity level?

A: All three connectors are classified as MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage and handling.
