Engineering Selection Recommendations

TE Connectivity DT06-12SB-CE04 and TE Connectivity DT06-12SB-CE13 are active-status alternatives manufactured by TE Connectivity Deutsch Connectors. Both maintain full electrical and mechanical compatibility with the Molex 0934456521 and carry ROHS3 compliance certification. The DT06-12SB-CE13 variant includes sealed features, providing enhanced environmental protection compared to the standard DT06-12SB-CE04 configuration.

Amphenol AT06-12SB-SR2BK is an active-status alternative from Amphenol Sine Systems Corp, offering equivalent 12-position plug functionality with additional integrated features including cap cover and strain relief. This part maintains ROHS3 compliance and MSL 1 rating consistent with the original Molex component. Note that contacts are not included with this housing and must be sourced separately.

All three substitute parts are currently in active production with substantial inventory availability, ensuring supply chain continuity for applications requiring the Molex 0934456521 specification.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity DT06-12SB-CE04 directly replace the Molex 0934456521?

A: Yes. Both connectors share identical 12-position plug configuration, 2-row arrangement, 0.359" pitch, crimp termination, and latch lock fastening. Operating temperature ranges and insulation materials are equivalent, ensuring functional compatibility.

Q: What is the difference between DT06-12SB-CE04 and DT06-12SB-CE13?

A: The DT06-12SB-CE13 includes sealed features and enhanced key configuration, providing additional environmental protection. Both maintain identical position count, pitch, and termination specifications.

Q: Does the Amphenol AT06-12SB-SR2BK require additional components?

A: Yes. The AT06-12SB-SR2BK is a housing-only component. Contacts must be sourced separately and are not included with this part.

Q: Are all substitute parts RoHS compliant?

A: Yes. All three substitute parts carry ROHS3 compliance certification, meeting current environmental and regulatory requirements.

Q: What is the significance of MSL rating for these connectors?

A: MSL 1 (Unlimited) indicates no moisture sensitivity restrictions during storage or handling. The Molex 0934456521 and Amphenol AT06-12SB-SR2BK both carry this rating. TE Connectivity parts are rated as Not Applicable, indicating no moisture sensitivity constraints.

Q: Can these connectors be used interchangeably in existing assemblies?

A: Mechanical and electrical compatibility is maintained across all listed parts. Physical form factor, pitch, and contact arrangement are equivalent. Verification of mating connector compatibility with existing harnesses is recommended prior to implementation.
