Key Parameters

Substitute Part Grouping Explanation

Substitution of the ACT96MD18PN-3025 is determined by strict alignment of the following parameters:

Critical Matching Parameters:

• Connector type: Plug with male pins
• Position count: 18 positions
• Shell size classification: 15-18 insert size
• Termination method: Crimp
• Fastening mechanism: Threaded
• Shielding requirement: Shielded
• Contact finish: Gold plating on mating surfaces
• Operating temperature range: -65°C to 200°C minimum
• Series compliance: MIL-DTL-38999 Series III

Acceptable Variations:

• Shell material composition (composite or stainless steel)
• Shell finish type (nickel or electroless nickel or passivated)
• Contact finish thickness (50.0µin to 100.0µin)
• Orientation designation (Normal or Alternate)
• Ingress protection rating (Environment Resistant or IP67)
• RoHS compliance status
• Manufacturer identity

Substitute parts must satisfy all critical matching parameters while allowing variation in the acceptable categories. Parts that deviate from critical parameters are not electrically or mechanically compatible.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Full Specification Alignment):

CTVS06RF-15-18P and CTVS06RF-15-18HA (Amphenol Aerospace Operations) satisfy all critical matching parameters with complete specification documentation. Both parts are actively produced, feature MIL-DTL-38999 Series III compliance, and maintain the required 18-position configuration with crimp termination and threaded fastening. The CTVS06RF-15-18P variant matches the Normal orientation of the original part. Both Amphenol alternatives achieve ROHS3 compliance, providing environmental regulatory advantage over the discontinued ACT96MD18PN-3025.

D38999/26KD18PN (Souriau-Sunbank by Eaton) provides full electrical and mechanical compatibility with documented 7.5A current rating matching the original specification. This part maintains MIL-DTL-38999 Series III compliance and operates across the identical temperature range. The stainless steel shell with passivated finish and IP67 ingress protection rating offer enhanced environmental durability compared to the composite shell of the original part. Product status is active with established supply availability.

Secondary Substitute (Limited Specification Data):

D38999/26WD18PN (Glenair) is listed as an equivalent alternative based on part number designation and active product status. However, complete electrical and mechanical specifications are not provided in available documentation. This part should be cross-referenced against detailed manufacturer datasheets prior to final selection to confirm alignment with all critical parameters.

Compliance Considerations:

Selection between RoHS-compliant alternatives (Amphenol CTVS06RF series) and non-compliant options (Souriau-Sunbank D38999/26KD18PN) depends on end-application regulatory requirements. Aerospace and military applications may impose specific compliance mandates that override general RoHS considerations.

Frequently Asked Questions (FAQ)

Q: Can CTVS06RF-15-18HA and CTVS06RF-15-18P be used interchangeably with ACT96MD18PN-3025?

A: Both Amphenol parts satisfy the critical substitution parameters: 18-position plug configuration, crimp termination, threaded fastening, shielded design, gold-plated contacts, and -65°C to 200°C operating range. The CTVS06RF-15-18P matches the Normal orientation of the original part. Physical and electrical compatibility is established through MIL-DTL-38999 Series III compliance. Mechanical fit and mating interface alignment should be verified against specific application requirements.

Q: What is the difference between CTVS06RF-15-18HA and CTVS06RF-15-18P?

A: The primary difference is connector orientation: CTVS06RF-15-18HA features Alternate orientation, while CTVS06RF-15-18P features Normal orientation. The CTVS06RF-15-18P directly matches the orientation designation of the ACT96MD18PN-3025. Contact finish thickness also differs: CTVS06RF-15-18HA specifies 100.0µin (2.54µm) while CTVS06RF-15-18P specifies 50.0µin (1.27µm). Both thicknesses fall within acceptable gold plating ranges for MIL-DTL-38999 Series III connectors.

Q: Is D38999/26KD18PN a direct replacement for ACT96MD18PN-3025?

A: D38999/26KD18PN meets all critical electrical and mechanical parameters: 18-position male plug, crimp termination, threaded fastening, shielded configuration, gold contacts, 7.5A current rating, and -65°C to 200°C temperature range. The primary difference is shell material composition: stainless steel with passivated finish versus composite with nickel finish. The D38999/26KD18PN provides IP67 ingress protection compared to Environment Resistant rating of the original. Compatibility depends on application-specific environmental and material requirements.

Q: Why is D38999/26WD18PN listed as a substitute if specifications are incomplete?

A: D38999/26WD18PN is identified as an equivalent based on the part number designation system and active product status. The part number structure indicates 18-position configuration and MIL-DTL-38999 compliance. However, complete technical specifications are not available in the provided documentation. Detailed manufacturer datasheets must be consulted to confirm all critical parameters before final selection.

Q: What are the key parameters that determine substitution compatibility?

A: Substitution compatibility is determined by: connector type (plug with male pins), position count (18), shell size classification (15-18), termination method (crimp), fastening type (threaded), shielding (shielded), contact finish (gold), operating temperature range (-65°C to 200°C minimum), and MIL-DTL-38999 Series III compliance. Variations in shell material, shell finish, contact finish thickness, orientation, and ingress protection rating are acceptable provided all critical parameters align.

Q: Are there inventory considerations when selecting a substitute?

A: Current inventory levels are: ACT96MD18PN-3025 (631 units), CTVS06RF-15-18HA (796 units), CTVS06RF-15-18P (1034 units), D38999/26KD18PN (892 units), and D38999/26WD18PN (858 units). All substitute options maintain active stock availability. Selection should account for lead time requirements and long-term supply chain stability, particularly given the discontinued status of the original part.

Q: Does RoHS compliance affect functional compatibility?

A: RoHS compliance status does not affect electrical or mechanical compatibility. CTVS06RF-15-18HA and CTVS06RF-15-18P are ROHS3 compliant, while ACT96MD18PN-3025 and D38999/26KD18PN are RoHS non-compliant. Selection between compliant and non-compliant alternatives depends on end-application regulatory requirements and customer specifications, not on connector functionality.
