Engineering Selection Recommendations

D38999/20JA35PN (Amphenol Aerospace Operations)

This substitute maintains full mechanical and electrical compatibility with the DTS20F9-35PN. The part is currently active in production, ensuring availability for procurement. The composite shell construction with olive drab cadmium finish provides enhanced environmental resistance compared to the aluminum shell of the original part. The operating temperature range of -65°C to 175°C covers the majority of applications, with the exception of systems requiring operation above 175°C. The addition of shielding provides electromagnetic interference protection. RoHS non-compliance status matches the original part. This substitute is suitable for aerospace, aviation, marine, and military applications.

D38999/20MA35PN (TE Connectivity Deutsch Connectors)

This substitute is manufactured by the same supplier as the original part, ensuring design consistency and manufacturing familiarity. The part maintains the full operating temperature range of -65°C to 200°C, matching the original specification. The composite shell with electroless nickel finish provides corrosion resistance. ROHS3 compliance status represents an improvement over the original part's RoHS non-compliance. The addition of shielding provides electromagnetic interference protection. Voltage rating specifications (400VAC, 550VDC) are provided for this variant. The part is classified as obsolete, which may impact long-term availability. This substitute is suitable for aviation, communication systems, industrial, and military applications.

Frequently Asked Questions (FAQ)

Q: Can D38999/20JA35PN be used as a direct replacement for DTS20F9-35PN?

A: Yes. Both connectors share identical specifications for connector type, number of positions, shell size, mounting configuration, termination method, fastening type, orientation, contact finish, contact material, contact finish thickness, and insert material. Both comply with MIL-DTL-38999 Series III. The D38999/20JA35PN is currently in active production status.

Q: What is the difference between the operating temperature ranges?

A: The DTS20F9-35PN operates from -65°C to 200°C. The D38999/20JA35PN operates from -65°C to 175°C. The D38999/20MA35PN operates from -65°C to 200°C. Applications requiring operation above 175°C must use either the original DTS20F9-35PN or the D38999/20MA35PN.

Q: Are there differences in shell material between the substitutes?

A: The original DTS20F9-35PN features an aluminum shell with nickel finish. Both substitutes use composite shell materials. D38999/20JA35PN has an olive drab cadmium finish, while D38999/20MA35PN has an electroless nickel finish. Composite shells provide enhanced environmental resistance compared to aluminum.

Q: Does the addition of shielding affect compatibility?

A: The D38999/20JA35PN and D38999/20MA35PN both include shielding, while the original DTS20F9-35PN does not specify shielding. Shielded variants provide electromagnetic interference protection and are compatible with unshielded mating components. The presence of shielding does not prevent mechanical or electrical mating.

Q: What is the difference in ingress protection?

A: The DTS20F9-35PN is specified as environment sealed. Both substitutes are specified as environment resistant. Environment sealed provides a higher level of protection against moisture and contaminant ingress than environment resistant.

Q: Which substitute has the best compliance status?

A: The D38999/20MA35PN is ROHS3 compliant, representing an improvement over the original part's RoHS non-compliance. The D38999/20JA35PN maintains RoHS non-compliance status matching the original part. Both substitutes are affected by REACH regulations.

Q: What is the current availability status of each substitute?

A: The D38999/20JA35PN is in active production status with 697 pieces in stock. The D38999/20MA35PN is classified as obsolete, which may impact future availability. The original DTS20F9-35PN is discontinued at DiGi Electronics with 775 pieces in stock.
