Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 1-1445052-1 is determined by strict equivalence across the following critical parameters:

Primary Matching Criteria:

• Connector type: Header
• Contact type: Male Pin
• Number of positions: 11
• Number of rows: 1
• Pitch - mating: 0.118" (3.00mm)
• Mounting type: Surface Mount
• Shrouding: Shrouded - 4 Wall
• Termination: Solder
• Fastening type: Locking Ramp
• Contact material: Brass
• Material flammability rating: UL94 V-0
• Style: Board to Cable/Wire

All identified substitute parts are manufactured by Molex under the Micro-Fit 3.0 43650 series. These parts maintain identical mechanical and electrical interface specifications with the original TE Connectivity component. Variations exist only in contact finish specifications and insulation material composition, which do not affect functional interchangeability for standard applications.

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: Molex 0436501121 or 0436501124

Both Molex 0436501121 and 0436501124 are functionally equivalent to the TE Connectivity 1-1445052-1. These parts are active products with ROHS3 compliance and REACH unaffected status, addressing the regulatory limitations of the obsolete original component. Molex 0436501124 is packaged in Tape & Reel format, suitable for automated assembly processes.

Alternative Options with Enhanced Contact Finish:

Molex 0436501122, 0436501123, and 0436501126 provide gold-plated mating contact finishes (15.0µin to 30.0µin thickness) as alternatives to the tin finish. These variants maintain identical mechanical and electrical interface specifications and are suitable for applications requiring enhanced corrosion resistance or improved contact reliability.

Compliance Advantage:

All Molex substitute parts are ROHS3 compliant and REACH unaffected, providing regulatory compliance superior to the RoHS non-compliant original TE Connectivity component. This compliance status is critical for new designs and manufacturing environments subject to environmental regulations.

Insulation Material Consideration:

Molex substitutes utilize Liquid Crystal Polymer (LCP) glass-filled insulation material, compared to the polyamide nylon insulation of the original part. LCP provides superior thermal and mechanical properties while maintaining UL94 V-0 flammability rating equivalence.

Frequently Asked Questions (FAQ)

Q: Are the Molex Micro-Fit 3.0 43650 series connectors mechanically compatible with the TE Connectivity Micro MATE-N-LOK 1-1445052-1?

A: Yes. Both connector families maintain identical mating pitch (0.118" / 3.00mm), 11-position single-row configuration, shrouded 4-wall construction, and locking ramp fastening. The mechanical interface is fully compatible for board-to-cable/wire applications.

Q: What is the difference between Molex 0436501121 and 0436501124?

A: Both parts are electrically and mechanically identical. The primary difference is packaging: 0436501121 is supplied in Tape & Reel format, while 0436501124 is also Tape & Reel packaged. Both feature tin mating contact finish at 100.0µin thickness. Selection depends on inventory management and assembly process requirements.

Q: Why do some substitute parts have gold-plated contacts while others have tin?

A: Molex 0436501122, 0436501123, and 0436501126 feature gold-plated mating contacts (15.0µin to 30.0µin thickness) for enhanced corrosion resistance and contact reliability in demanding environments. Molex 0436501121 and 0436501124 feature tin mating contacts (100.0µin thickness) for standard applications. Selection depends on environmental exposure and reliability requirements.

Q: Is the insulation height difference between the original part (0.364") and Molex substitutes (0.390") significant?

A: The 0.026" (0.66mm) insulation height difference reflects design evolution in the Micro-Fit 3.0 series. This difference does not affect functional compatibility for standard board-to-cable applications. Verify clearance in space-constrained designs.

Q: What is the advantage of ROHS3 compliance in the Molex substitutes?

A: ROHS3 compliance eliminates lead and other restricted substances, meeting environmental regulations required in most manufacturing jurisdictions. The original TE Connectivity part is RoHS non-compliant, making Molex substitutes mandatory for new designs and regulated manufacturing environments.

Q: Can I use these connectors interchangeably in existing designs?

A: Yes, for standard applications. The Molex Micro-Fit 3.0 43650 series maintains full mechanical and electrical interface compatibility with the TE Connectivity Micro MATE-N-LOK 1-1445052-1. Verify mating connector compatibility and environmental requirements for your specific application.

Q: What packaging options are available for these substitute parts?

A: Molex 0436501121, 0436501124, and 0436501126 are supplied in Tape & Reel (TR) packaging, suitable for automated pick-and-place assembly. Molex 0436501122 and 0436501123 are available in standard packaging. Confirm packaging requirements with your procurement process.

Q: Are all substitute parts rated for the same operating temperature range?

A: Operating temperature specifications are not provided for the Molex substitute parts in the available data. The original TE Connectivity part is rated -40°C to 105°C. Consult Molex technical documentation for specific operating temperature ratings of substitute parts if this parameter is critical for your application.
