Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ACT90MB99SN are identified based on strict equivalence across the following critical parameters:

Core Compatibility Criteria:

• Connector type: Receptacle, Female Sockets
• Number of positions: 7
• Shell size - insert: 11-99
• Mounting type: Panel Mount with Flange
• Termination method: Crimp
• Fastening type: Threaded
• Orientation: N (Normal)
• Shell material: Composite
• Contact finish - mating: Gold
• Shielding: Shielded
• Contact material: Copper Alloy
• Insert material: Thermoplastic
• Ingress protection: Environment Resistant
• MIL-DTL-38999 Series III qualification

The substitute parts CTVP00RW-11-99JN and CTVPS00RF-11-99JN satisfy all core compatibility criteria. Variations in shell finish, operating temperature upper limits, contact finish thickness, and RoHS compliance status are secondary parameters that do not affect mechanical or electrical interchangeability for the specified connector interface.

Parameter Comparison

Engineering Selection Recommendations

CTVPS00RF-11-99JN is the primary substitute for ACT90MB99SN. This part maintains full mechanical and electrical compatibility across all critical parameters, including the operating temperature range of -65°C to 200°C. CTVPS00RF-11-99JN is currently active in production and carries ROHS3 compliance, providing regulatory advantage for new designs and long-term procurement stability. The contact finish thickness of 100.0µin (2.54µm) exceeds the original specification of 50.0µin (1.27µm), providing enhanced durability and contact reliability.

CTVP00RW-11-99JN is an alternative substitute that maintains full mechanical and electrical compatibility. This part is active in production and available in inventory. The operating temperature upper limit is 175°C, which is 25°C lower than the original ACT90MB99SN specification. Selection of CTVP00RW-11-99JN is appropriate for applications where the maximum operating temperature does not exceed 175°C. The olive drab cadmium shell finish and higher contact finish thickness (100.0µin) are secondary characteristics that do not affect connector interface compatibility.

Both substitute parts are qualified to MIL-DTL-38999 Series III and maintain the same mechanical interface, pin configuration, and electrical characteristics required for direct replacement in aerospace and military applications.

Frequently Asked Questions (FAQ)

Q: Can CTVPS00RF-11-99JN or CTVP00RW-11-99JN be used as direct replacements for ACT90MB99SN?

A: Yes. Both substitute parts maintain identical mechanical interfaces, pin configurations, and electrical characteristics across all critical parameters including connector type, number of positions, shell size, mounting configuration, termination method, and shielding. Both are qualified to MIL-DTL-38999 Series III.

Q: What is the difference between the two substitute parts?

A: The primary differences are operating temperature range and RoHS compliance. CTVPS00RF-11-99JN operates from -65°C to 200°C and is ROHS3 compliant. CTVP00RW-11-99JN operates from -65°C to 175°C and is RoHS non-compliant. Both have identical mechanical interfaces and are electrically interchangeable.

Q: Which substitute should I select for a new design?

A: CTVPS00RF-11-99JN is recommended for new designs. It provides the full operating temperature range matching the original part, carries ROHS3 compliance for regulatory alignment, and is actively produced by Amphenol Aerospace Operations.

Q: Does the shell finish difference affect compatibility?

A: No. Shell finish variations (nickel, olive drab cadmium, or electroless nickel) are cosmetic and environmental protection characteristics that do not affect the mechanical interface or electrical performance of the connector.

Q: Why is the contact finish thickness different on the substitute parts?

A: The substitute parts feature 100.0µin (2.54µm) contact finish thickness compared to the original 50.0µin (1.27µm). This increased thickness provides enhanced durability and contact reliability while maintaining full electrical compatibility.

Q: Are there any temperature limitations when substituting CTVP00RW-11-99JN?

A: CTVP00RW-11-99JN has a maximum operating temperature of 175°C, which is 25°C lower than the original ACT90MB99SN. This part is suitable for applications where the maximum operating temperature does not exceed 175°C. For applications requiring the full -65°C to 200°C range, CTVPS00RF-11-99JN is the appropriate selection.

Q: What is the inventory status of the substitute parts?

A: CTVPS00RF-11-99JN has 960 pieces in stock. CTVP00RW-11-99JN has 839 pieces in stock. Both are actively produced and available for procurement.

Q: Do the substitute parts maintain MIL-DTL-38999 Series III qualification?

A: Yes. Both CTVPS00RF-11-99JN and CTVP00RW-11-99JN are qualified to MIL-DTL-38999 Series III, ensuring compliance with military connector standards and specifications.
