• Contact finish (mating surface): Gold
• Voltage rating: 250V minimum

Mechanical Compatibility:

• Connector style: Board to Cable/Wire
• Mounting configuration: Through hole, right angle
• Shrouding: Shrouded - 4 wall
• Termination method: Solder
• Fastening mechanism: Locking ramp
• Flammability rating: UL94 V-0

Regulatory & Environmental:

• RoHS3 compliance
• Moisture sensitivity level: 1 (Unlimited)
• Operating temperature range: -40°C to 105°C minimum

The substitute parts identified (Molex 0436501202 and 0436501205) satisfy all critical electrical and mechanical parameters. Both are active products from an established connector manufacturer, providing continuity for applications requiring the TE Connectivity 3-1445089-2 specification.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The TE Connectivity 3-1445089-2 is classified as obsolete. Both Molex substitute parts (0436501202 and 0436501205) maintain active product status, ensuring ongoing availability, technical support, and manufacturing continuity.

Compliance & Certification: All three connectors achieve UL94 V-0 flammability rating and ROHS3 compliance. The Molex alternatives carry REACH Unaffected status, providing additional regulatory clarity for international applications. The TE Connectivity original part lists REACH status as Vendor Undefined.

Electrical & Mechanical Equivalence: The Molex 0436501202 and 0436501205 satisfy all critical electrical parameters: 12-position, 3.00mm pitch, male pin contacts with gold-plated mating surfaces, 250V minimum voltage rating, and brass contact material. Mechanical compatibility is confirmed through identical mounting configuration (through-hole, right-angle), shrouding design (4-wall), termination method (solder), and fastening mechanism (locking ramp).

Insulation Material Difference: The TE Connectivity original employs Polyamide (PA) Nylon insulation, while both Molex substitutes utilize Liquid Crystal Polymer (LCP) Glass Filled insulation. Both materials achieve UL94 V-0 rating and support the specified operating temperature range and moisture sensitivity level.

Physical Dimension Variance: Contact post length differs between the original (0.138" / 3.50mm) and substitutes (0.125" / 3.18mm). Insulation height also varies: original at 0.152" (3.85mm) versus substitutes at 0.172" (4.37mm). These dimensional differences require verification against specific board layout and mating connector specifications.

Frequently Asked Questions (FAQ)

Q: Are the Molex 0436501202 and 0436501205 fully interchangeable with the TE Connectivity 3-1445089-2?

A: Both Molex parts satisfy the critical electrical and mechanical parameters: 12-position, 3.00mm pitch, male pin headers with gold-plated contacts, through-hole right-angle mounting, shrouded 4-wall construction, and solder termination. However, physical dimensions differ in contact post length and insulation height. Compatibility depends on specific board layout and mating connector design. Direct mechanical fit must be confirmed against your application's physical constraints.

Q: What is the difference between Molex 0436501202 and 0436501205?

A: Both parts are identical in electrical and mechanical specifications. They are both Molex Micro-Fit 3.0 43650 series connectors with 12 positions at 3.00mm pitch. The part numbers represent the same connector design with equivalent performance characteristics.

Q: Why does the TE Connectivity part show as obsolete?

A: The TE Connectivity 3-1445089-2 is designated obsolete, indicating it is no longer in active production. The Molex alternatives (0436501202 and 0436501205) are active products, providing continuity for new designs and replacement applications.

Q: Are there temperature or voltage limitations with the Molex substitutes?

A: The Molex 0436501202 and 0436501205 do not specify operating temperature range or voltage rating in their technical data. The TE Connectivity original specifies -40°C to 105°C operating temperature and 250V voltage rating. For applications requiring these specifications, confirmation of Molex part performance under these conditions is necessary.

Q: What is the significance of the insulation material change from Nylon to LCP?

A: Both Polyamide (PA) Nylon and Liquid Crystal Polymer (LCP) Glass Filled achieve UL94 V-0 flammability rating. LCP offers enhanced dimensional stability and chemical resistance. Both materials support the MSL 1 (Unlimited) moisture sensitivity level. The material change does not affect electrical performance or regulatory compliance for standard applications.

Q: How do the physical dimension differences affect compatibility?

A: The contact post length reduction from 0.138" to 0.125" and insulation height increase from 0.152" to 0.172" may impact board layout and mating connector alignment. These dimensions must be verified against your specific PCB design and mating connector specifications to ensure proper fit and electrical contact.

Q: Are both Molex parts available in the same packaging?

A: Both Molex 0436501202 and 0436501205 are supplied in Tray packaging. The TE Connectivity original does not specify packaging type in the provided data.

Q: Do the substitutes support the same applications as the original?

A: The Molex substitutes list applications as General Purpose, Medical, Military, and Telecommunications. The TE Connectivity original specifies General Purpose applications. The expanded application scope of the Molex parts indicates broader suitability for specialized environments.
