Engineering Selection Recommendations

Primary Substitute: CTVS06RF-11-98S-506

The CTVS06RF-11-98S-506 manufactured by Amphenol Aerospace Operations is the preferred substitute for the ACT96WB98SN. This part maintains all mandatory mechanical and electrical parameters including 6-position configuration, 11-98 shell sizing, crimp termination, threaded fastening, and gold-plated copper alloy contacts with 50.0µin finish thickness. The connector qualifies to MIL-DTL-38999 Series III specifications and operates across the extended temperature range of -65°C to 200°C, exceeding the original part's -65°C to 175°C specification. The part is currently active in production with 2254 units in stock. ROHS3 compliance provides environmental regulatory advantage over the discontinued original part.

Secondary Substitute: D38999/26FB98SN

The D38999/26FB98SN manufactured by Amphenol Aerospace Operations provides an alternative with aluminum shell construction versus the composite shell of the original part. This connector maintains all critical electrical and mechanical parameters, including 6-position female socket configuration, 11-98 shell sizing, crimp termination, and gold contact finish at 50.0µin thickness. Operating temperature extends to 200°C, and the part qualifies to MIL-DTL-38999 Series III. The aluminum shell construction offers enhanced durability in certain environmental conditions. The part is active with 872 units in stock and carries ROHS3 compliance.

Tertiary Substitute: D38999/26MB98SN

The D38999/26MB98SN manufactured by Souriau-Sunbank by Eaton maintains composite shell construction identical to the original part. This connector provides 6-position female socket configuration, 11-98 shell sizing, crimp termination, and 7.5A current rating matching the original specification. Operating temperature extends to 200°C, and ingress protection is rated IP67 for enhanced environmental sealing. The part qualifies to MIL-DTL-38999 Series III and is currently active with 867 units in stock. RoHS non-compliance status matches the original part.

Compliance Considerations:

CTVS06RF-11-98S-506 and D38999/26FB98SN provide ROHS3 compliance, offering regulatory advantage for new designs and applications subject to environmental directives. D38999/26MB98SN maintains RoHS non-compliant status consistent with the original part, suitable for legacy system replacements where compliance status must remain unchanged.

Frequently Asked Questions (FAQ)

Q: Can the CTVS06RF-11-98S-506 directly replace the ACT96WB98SN in existing assemblies?

A: Yes. The CTVS06RF-11-98S-506 maintains identical mechanical and electrical parameters including 6-position configuration, 11-98 shell sizing, crimp termination, threaded fastening, and gold contact specifications. The connector is mechanically and electrically interchangeable. The extended operating temperature range (-65°C to 200°C versus -65°C to 175°C) provides additional thermal margin without affecting compatibility.

Q: What is the difference between composite and aluminum shell construction?

A: The ACT96WB98SN and D38999/26MB98SN feature composite shells, while the D38999/26FB98SN uses aluminum construction. Both materials meet MIL-DTL-38999 Series III specifications. Aluminum shells provide enhanced mechanical strength and thermal conductivity, while composite shells offer weight reduction and corrosion resistance. Selection depends on application-specific environmental and structural requirements.

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

A: CTVS06RF-11-98S-506, D38999/26FB98SN, and D38999/26MB98SN all qualify to MIL-DTL-38999 Series III specifications. D38999/26SB98SN does not provide explicit military qualification documentation in the available parameters.

Q: What is the significance of the 50.0µin (1.27µm) contact finish thickness?

A: The 50.0µin gold plating thickness on copper alloy contacts ensures consistent mating surface conductivity, corrosion resistance, and contact reliability across the connector's operational life. All primary substitute parts maintain this specification, ensuring equivalent electrical performance and durability.

Q: Does RoHS compliance affect functional compatibility?

A: RoHS compliance status does not affect electrical or mechanical compatibility. ROHS3-compliant parts (CTVS06RF-11-98S-506 and D38999/26FB98SN) are suitable for applications requiring environmental regulatory compliance. RoHS non-compliant parts (D38999/26MB98SN) are appropriate for legacy system replacements where compliance status must remain unchanged.

Q: What is the current rating specification, and why does it matter?

A: The ACT96WB98SN and D38999/26MB98SN are rated for 7.5A continuous current. CTVS06RF-11-98S-506 and D38999/26FB98SN do not provide explicit current rating specifications in available documentation. For applications requiring confirmed 7.5A rating, D38999/26MB98SN provides direct specification match. Verify current requirements against application load specifications before final selection.

Q: What is the difference between Environment Resistant and IP67 ingress protection ratings?

A: Environment Resistant indicates general protection against environmental contamination. IP67 (Dust Tight, Waterproof) provides quantified protection against dust ingress and temporary immersion in water to 1 meter depth. D38999/26MB98SN with IP67 rating offers enhanced environmental sealing for applications requiring submersion or high-moisture exposure.

Q: Are there inventory considerations for substitute selection?

A: CTVS06RF-11-98S-506 has 2254 units in stock, D38999/26FB98SN has 872 units, and D38999/26MB98SN has 867 units available. Inventory levels support immediate procurement for all primary substitute options.
