Substitute Part Grouping Explanation

Substitution of the ACT90MJ35SN is determined by strict equivalence across the following critical parameters:

Primary Compatibility Criteria:

Connector type: Receptacle, Female Sockets
Position count: 128 positions
Shell size: 25-35
Mounting configuration: Panel mount with flange
Termination method: Crimp
Fastening: Threaded
Orientation: Normal (N)
Contact finish: Gold plating on mating surfaces
Shielding: Shielded construction

Secondary Compatibility Criteria:

Engineering Selection Recommendations

Active Product Availability: All substitute parts listed are currently in active production status, ensuring long-term availability and supply chain continuity. The main part ACT90MJ35SN is discontinued, making substitution necessary for ongoing support.

RoHS Compliance Consideration: CTVPS00RF-25-35J and CTVPS00RF-25-35JN are ROHS3 compliant, providing environmental compliance advantages for new designs and applications subject to RoHS regulations. Remaining substitutes maintain RoHS non-compliant status consistent with the original part.

Operating Temperature Range: CTVP00RW-25-35JN and D38999/20WJ35SN operate to -65°C ~ 175°C, which is 25°C lower than the main part specification of -65°C ~ 200°C. Selection of these parts requires verification that system operating temperatures do not exceed 175°C. CTVPS00RF-25-35J, CTVPS00RF-25-35JN, and D38999/20FJ35SN maintain the full -65°C ~ 200°C operating range.

Ingress Protection: D38999/20FJ35SN provides IP67 rating (dust tight, waterproof), exceeding the environment resistant specification of the original part. This enhanced protection is suitable for applications requiring superior environmental sealing.

Inventory Availability: D38999/20WJ35SN offers the highest inventory level at 15,800 pieces, providing immediate availability for high-volume requirements. CTVPS00RF-25-35J provides 1,140 pieces with ROHS3 compliance.

Frequently Asked Questions (FAQ)

Q: Can CTVP00RW-25-35JN be used as a direct replacement for ACT90MJ35SN?

A: CTVP00RW-25-35JN meets all primary compatibility criteria including 128 positions, 25-35 shell size, crimp termination, and gold-plated contacts. However, its operating temperature range is -65°C ~ 175°C, which is 25°C lower than the original part. Selection requires confirmation that system operating temperatures remain within 175°C maximum.

Q: What is the difference between CTVPS00RF-25-35J and CTVPS00RF-25-35JN?

A: Both parts are functionally equivalent with identical electrical and mechanical specifications. The primary difference is shell finish: CTVPS00RF-25-35J features nickel finish, while CTVPS00RF-25-35JN features electroless nickel finish. Both maintain -65°C ~ 200°C operating temperature and ROHS3 compliance.

Q: Why does D38999/20FJ35SN have IP67 rating while others specify environment resistant?

A: D38999/20FJ35SN incorporates aluminum shell construction with specific sealing design that achieves IP67 dust-tight and waterproof performance. This represents enhanced environmental protection compared to environment resistant specification. Both ratings satisfy the ingress protection requirement; IP67 provides additional margin for harsh environments.

Q: Are there differences in shell material between substitute options?

A: Yes. ACT90MJ35SN uses composite shell material. Substitute parts vary: CTVP00RW-25-35JN, CTVPS00RF-25-35J, and CTVPS00RF-25-35JN use composite shells; D38999/20FJ35SN and D38999/20WJ35SN use aluminum shells. Shell material does not affect electrical compatibility when all contact and termination specifications match.

Q: Which substitute part offers the best compliance for new designs?

A: CTVPS00RF-25-35J and CTVPS00RF-25-35JN are ROHS3 compliant, meeting environmental regulations for new product designs. Both maintain full -65°C ~ 200°C operating temperature range and 128-position, 25-35 shell size specifications identical to the original part.

Q: What is the significance of contact finish thickness differences?

A: ACT90MJ35SN and D38999/20WJ35SN specify 50.0µin (1.27µm) gold contact finish thickness. CTVP00RW-25-35JN, CTVPS00RF-25-35J, CTVPS00RF-25-35JN, and D38999/20FJ35SN specify 100.0µin (2.54µm) thickness. Thicker plating provides extended contact life and improved corrosion resistance. Both thicknesses satisfy gold plating requirements for crimp contact applications.

Q: Can D38999/20WJ35SN be used in applications requiring 200°C operation?

A: No. D38999/20WJ35SN operates to -65°C ~ 175°C maximum. Applications requiring sustained operation at temperatures above 175°C require selection of CTVPS00RF-25-35J, CTVPS00RF-25-35JN, or D38999/20FJ35SN, which all support -65°C ~ 200°C range.

Q: Are all substitute parts suitable for aerospace and military applications?

A: Yes. All substitute parts are specified for aerospace, military, aviation, or marine applications. CTVP00RW-25-35JN, CTVPS00RF-25-35J, CTVPS00RF-25-35JN, and D38999/20FJ35SN explicitly list aviation and military applications. D38999/20WJ35SN lists aviation, communication systems, industrial, and military applications. All conform to MIL-DTL-38999 Series III specifications.
