Key Parameters

Substitute Part Grouping Explanation

Substitution of the ACT90MD18SN-3025 is based on strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Connector type: Receptacle with female sockets
• Position count: 18 positions
• Shell size classification: 15-18 insert size, MIL size D
• Mounting configuration: Panel mount with flange
• Termination method: Crimp
• Fastening mechanism: Threaded
• Shielding requirement: Shielded
• Contact finish: Gold plating on mating surfaces
• Operating temperature range: -65°C to 200°C
• Series compliance: MIL-DTL-38999 Series III

The CTVPS00RF-15-18JN from Amphenol Aerospace Operations satisfies all mandatory parameters and qualifies as a direct functional equivalent.

Parameter Comparison

Engineering Selection Recommendations

The CTVPS00RF-15-18JN is a direct functional equivalent to the ACT90MD18SN-3025 across all critical electrical and mechanical parameters. Both connectors comply with MIL-DTL-38999 Series III specifications and maintain identical performance characteristics for aerospace and military applications.

Product Status Consideration: The ACT90MD18SN-3025 is discontinued at DiGi Electronics, while the CTVPS00RF-15-18JN maintains active product status with current inventory availability (778 pieces in stock).

Compliance Advantage: The CTVPS00RF-15-18JN achieves ROHS3 compliance, whereas the ACT90MD18SN-3025 is RoHS non-compliant. This distinction is relevant for procurement policies requiring RoHS-compliant components in new designs or applications subject to environmental regulations.

Contact Finish Specification: The CTVPS00RF-15-18JN provides documented contact finish thickness of 100.0µin (2.54µm) on mating surfaces, offering explicit specification data for quality assurance and traceability purposes.

Both connectors share identical moisture sensitivity levels (MSL 1), export classifications (EAR99), and tariff codes (8536.69.4020), ensuring compatibility with existing supply chain and regulatory documentation.

Frequently Asked Questions (FAQ)

Q: Can the CTVPS00RF-15-18JN directly replace the ACT90MD18SN-3025 in existing assemblies?

A: Yes. Both connectors are MIL-DTL-38999 Series III compliant receptacles with 18 positions, identical shell sizes (15-18 insert, MIL size D), matching termination methods (crimp), and equivalent operating temperature ranges (-65°C to 200°C). The mechanical and electrical interfaces are functionally identical.

Q: What is the primary difference between these two connectors?

A: The primary differences are manufacturer (TE Connectivity Deutsch Connectors versus Amphenol Aerospace Operations), product status (discontinued versus active), and RoHS compliance (non-compliant versus ROHS3 compliant). All functional parameters remain equivalent.

Q: Are there any compatibility concerns with mating connectors?

A: No compatibility concerns exist. Both receptacles conform to MIL-DTL-38999 Series III specifications and accept standard mating plugs designed for this series. The 18-position, size D configuration ensures mechanical and electrical compatibility with corresponding plug connectors.

Q: Does the CTVPS00RF-15-18JN support the same current rating?

A: The CTVPS00RF-15-18JN does not specify a current rating in the provided data. The ACT90MD18SN-3025 carries a 7.5A rating. For applications requiring explicit current rating confirmation, contact the manufacturer directly.

Q: What is the significance of the contact finish thickness specification on the CTVPS00RF-15-18JN?

A: The documented contact finish thickness of 100.0µin (2.54µm) provides measurable quality assurance data for gold plating on mating surfaces. This specification supports traceability and compliance verification in aerospace and military procurement environments.

Q: Are both connectors suitable for aerospace and military applications?

A: Yes. Both connectors are specified for aerospace and military applications. The CTVPS00RF-15-18JN additionally lists aviation and marine applications. Both maintain identical operating temperature ranges and environmental resistance ratings required for these demanding environments.

Q: What packaging format is available for the CTVPS00RF-15-18JN?

A: The CTVPS00RF-15-18JN is supplied in bulk packaging, with 778 pieces currently in stock.
