Equivalent & Substitute Parts for Molex 0934456621

Part Overview

The Molex 0934456621 is a 12-position rectangular connector housing from the XT series, designed for applications requiring sealed, latch-lock plug assemblies with crimp termination. This part is classified as obsolete, making identification of active equivalent and substitute components essential for ongoing system support and new design implementations. Substitute parts must maintain compatibility across connector type, position count, mounting configuration, and sealing characteristics to ensure proper system integration.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts are active products with current manufacturing status, providing long-term availability and supply chain stability compared to the obsolete Molex 0934456621.

AT06-12SB (Amphenol Sine Systems Corp): This part meets all compatibility requirements with thermoplastic insulation and Female Socket contact type. ROHS3 compliance and REACH unaffected status support regulatory requirements. Highest inventory availability (2,402 units) ensures supply continuity.

DT06-12SB-E008 (TE Connectivity Deutsch Connectors): This part meets all compatibility requirements with polyamide (PA66) glass-filled insulation and Male Pin contact type. ROHS3 compliance and REACH unaffected status support regulatory requirements. Specified pitch of 0.359" (9.12mm) provides dimensional clarity. Inventory of 1,305 units supports production needs.

AT06-12SB-SRBK (Amphenol Sine Systems Corp): This manufacturer-recommended substitute includes integrated Cap (Cover) and Strain Relief features beyond base sealing. Thermoplastic insulation and Female Socket contact type align with AT06-12SB. ROHS3 compliance and REACH unaffected status support regulatory requirements. Inventory of 1,207 units supports production requirements. Enhanced feature set may provide additional system protection.

Selection between these three parts depends on specific contact type requirements (Female Socket vs. Male Pin), insulation material specifications, and whether integrated strain relief and cap features are required for the application.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0934456621 be directly replaced with any of these substitute parts?

A: Yes. All three substitute parts (AT06-12SB, DT06-12SB-E008, and AT06-12SB-SRBK) meet the critical compatibility parameters: 12-position count, plug connector type, latch-lock fastening, sealed design, crimp termination, free-hanging mounting, and -55°C to 125°C operating range. The primary difference is contact type (Female Socket vs. Male Pin) and insulation material composition.

Q: What is the difference between AT06-12SB and AT06-12SB-SRBK?

A: Both parts are from Amphenol Sine Systems Corp with identical base specifications. AT06-12SB-SRBK includes additional integrated features: Cap (Cover) and Strain Relief. Both use thermoplastic insulation and Female Socket contacts. Selection depends on whether these additional protective features are required for the application.

Q: How do contact types affect substitution?

A: The Molex 0934456621 specifications do not explicitly define contact type. AT06-12SB and AT06-12SB-SRBK provide Female Socket contacts, while DT06-12SB-E008 provides Male Pin contacts. Contact type must be verified against mating connector requirements in the system design to ensure proper electrical connection.

Q: Are all substitute parts RoHS and REACH compliant?

A: Yes. All three substitute parts are ROHS3 compliant and REACH unaffected. The original Molex 0934456621 compliance status is not specified in available documentation.

Q: What is the significance of the pitch specification in DT06-12SB-E008?

A: The DT06-12SB-E008 specifies a pitch of 0.359" (9.12mm), which defines the center-to-center distance between contact positions. This specification provides dimensional clarity for mechanical integration. The other substitute parts do not specify pitch in available documentation.

Q: Which substitute part has the highest inventory availability?

A: AT06-12SB has the highest inventory with 2,402 units in stock, followed by DT06-12SB-E008 with 1,305 units and AT06-12SB-SRBK with 1,207 units.
