Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 1-1445056-2 is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Pitch - Mating: 0.118" (3.00mm)
• Number of Positions: 12
• Number of Rows: 1
• Connector Type: Header
• Contact Type: Male Pin
• Mounting Type: Surface Mount, Right Angle
• Shrouding: Shrouded - 4 Wall
• Termination: Solder
• Fastening Type: Locking Ramp
• Contact Material: Brass
• Material Flammability Rating: UL94 V-0
• Style: Board to Cable/Wire
• Number of Positions Loaded: All

The three Molex Micro-Fit 3.0 43650 series connectors (0436501209, 0436501212, 0436501214) satisfy all mandatory matching parameters. Variations exist in insulation material composition, contact finish specifications, and product status, which are documented in the parameter comparison table below.

Parameter Comparison

Engineering Selection Recommendations

All three Molex Micro-Fit 3.0 43650 series connectors (0436501209, 0436501212, 0436501214) are active products with full regulatory compliance status. The TE Connectivity 1-1445056-2 is obsolete and non-compliant with current RoHS3 requirements.

Selection Criteria by Regulatory and Compliance Status:

Molex 0436501209 is available in Cut Tape (CT) and Tape & Reel (TR) packaging with 1570 units in stock. This part carries ROHS3 compliance and REACH Unaffected status, suitable for applications requiring modern regulatory alignment.

Molex 0436501212 is supplied in Tape & Reel (TR) packaging with 1416 units in stock. This part includes Solder Retention feature and carries ROHS3 compliance and REACH Unaffected status.

Molex 0436501214 is supplied in Tape & Reel (TR) packaging with 864 units in stock. This part features gold mating contact finish with 30.0µin (0.76µm) thickness and includes Solder Retention feature. It carries ROHS3 compliance and REACH Unaffected status.

All three substitute parts maintain electrical and mechanical compatibility with the original TE Connectivity 1-1445056-2 connector. Differences in insulation material (LCP glass-filled versus polyamide nylon), contact finish specifications, and feature sets (Board Lock versus Solder Retention) are documented in the parameter comparison table and do not affect functional interchangeability for standard board-to-cable/wire applications.

Frequently Asked Questions (FAQ)

Q: Can Molex 0436501209, 0436501212, and 0436501214 directly replace TE Connectivity 1-1445056-2?

A: Yes. All three Molex parts maintain identical pitch (0.118" / 3.00mm), position count (12), row configuration (1), mounting type (surface mount right angle), shrouding (4-wall), termination method (solder), and fastening mechanism (locking ramp). These parameters define functional interchangeability for rectangular connector headers.

Q: What are the differences between the three Molex substitute options?

A: The primary differences are contact finish specifications and packaging format. Molex 0436501209 offers tin mating contact finish and is available in both Cut Tape and Tape & Reel formats. Molex 0436501212 provides tin mating contact finish with Solder Retention feature in Tape & Reel format. Molex 0436501214 features gold mating contact finish (30.0µin thickness) with Solder Retention feature in Tape & Reel format.

Q: Why does the TE Connectivity 1-1445056-2 require substitution?

A: The TE Connectivity 1-1445056-2 is classified as obsolete and does not comply with current RoHS3 requirements. All three Molex alternatives are active products with full ROHS3 compliance and REACH Unaffected status, ensuring regulatory alignment for new designs and ongoing production.

Q: Are there differences in insulation material between the original and substitute parts?

A: Yes. The TE Connectivity 1-1445056-2 uses Polyamide (PA) Nylon insulation material, while all three Molex substitutes use Liquid Crystal Polymer (LCP) glass-filled insulation. Both materials achieve UL94 V-0 flammability rating. The LCP material in Molex parts provides enhanced thermal and mechanical properties.

Q: What is the difference in insulation height between the original and substitute parts?

A: The TE Connectivity 1-1445056-2 has an insulation height of 0.152" (3.85mm), while all three Molex substitutes have an insulation height of 0.172" (4.37mm). This 0.020" (0.52mm) difference must be evaluated for mechanical fit in existing board layouts and mating cavity designs.

Q: Which Molex substitute should be selected for medical or military applications?

A: All three Molex substitutes (0436501209, 0436501212, 0436501214) list medical, military, and telecommunications applications in their specifications. Selection between them depends on contact finish requirements and packaging format needs for your specific application.

Q: What packaging formats are available for the Molex substitutes?

A: Molex 0436501209 is available in both Cut Tape (CT) and Tape & Reel (TR) formats. Molex 0436501212 and 0436501214 are supplied in Tape & Reel (TR) format only.

Q: Are all substitute parts RoHS compliant?

A: Yes. All three Molex substitutes (0436501209, 0436501212, 0436501214) are ROHS3 compliant, whereas the original TE Connectivity 1-1445056-2 is RoHS non-compliant. This compliance status is a key factor in the substitution requirement.

Q: What is the difference in contact finish between the Molex options?

A: Molex 0436501209 and 0436501212 feature tin mating contact finish with 60.0µin (1.52µm) thickness. Molex 0436501214 features gold mating contact finish with 30.0µin (0.76µm) thickness. Gold finish provides enhanced corrosion resistance and is typically specified for high-reliability applications.
