• Number of Positions: 11
• Number of Rows: 1
• Mounting Type: Surface Mount
• Shrouding: Shrouded - 4 Wall
• Termination: Solder
• Fastening Type: Locking Ramp
• Contact Material: Brass
• Contact Shape: Square
• Material Flammability Rating: UL94 V-0

All four Molex Micro-Fit 3.0 43650 series parts (0436501121, 0436501122, 0436501123, 0436501126) satisfy these mandatory parameters. Variations in contact finish specifications and insulation material composition do not preclude functional substitution, as these represent design enhancements in the active product line.

Parameter Comparison

Engineering Selection Recommendations

All four Molex Micro-Fit 3.0 43650 series substitute parts are functionally equivalent to the TE Connectivity 1-1445095-1 based on critical connector parameters. The following factors support selection:

Product Status: The TE Connectivity 1-1445095-1 is obsolete. All substitute parts maintain active product status, ensuring long-term availability and supply chain continuity.

Regulatory Compliance: All substitute parts are ROHS3 compliant and REACH unaffected, representing compliance improvements over the original non-compliant part. This is advantageous for new designs and ongoing production requiring regulatory adherence.

Connector Geometry: All substitutes maintain identical pitch (3.00mm), position count (11), row configuration (1), and shrouding (4-wall) specifications, ensuring mechanical and electrical compatibility with existing mating connectors and PCB layouts.

Contact Finish Variations: The substitute parts offer three contact finish options for mating surfaces: tin (0436501121), gold at 15.0µin (0436501122), and gold at 30.0µin (0436501123, 0436501126). The original part specifies gold at 30.0µin, making 0436501123 and 0436501126 the closest electrical equivalents.

Insulation Material: Molex substitutes employ Liquid Crystal Polymer (LCP) glass-filled insulation, which provides enhanced thermal and mechanical properties compared to the original polyamide/nylon composition. This represents a design improvement without compromising compatibility.

Packaging Considerations: Molex 0436501121 and 0436501126 are supplied in Tape & Reel (TR) packaging, suitable for automated assembly. Molex 0436501122 and 0436501123 are supplied in standard packaging. Selection depends on production methodology requirements.

Frequently Asked Questions (FAQ)

Q: Can Molex 0436501121 directly replace the TE Connectivity 1-1445095-1?

A: Yes. The Molex 0436501121 satisfies all mandatory connector parameters including pitch, position count, mounting type, shrouding, termination, and fastening specifications. The tin contact finish on the mating surface differs from the original gold specification but does not preclude functional substitution in applications where contact resistance and corrosion resistance requirements are within acceptable limits.

Q: What is the difference between Molex 0436501122, 0436501123, and 0436501126?

A: All three parts are functionally equivalent with identical connector geometry and electrical specifications. The differences are: (1) Contact finish thickness on the mating surface: 0436501122 specifies 15.0µin gold, while 0436501123 and 0436501126 specify 30.0µin gold, matching the original part specification; (2) Packaging: 0436501126 is supplied in Tape & Reel format, while 0436501122 and 0436501123 use standard packaging; (3) Features: 0436501126 includes solder retention, while 0436501122 and 0436501123 include board lock.

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

A: The insulation height difference of 0.026" (0.66mm) reflects design improvements in the Molex Micro-Fit 3.0 series. This dimension does not affect mating compatibility with standard cable connectors. PCB layout and clearance considerations should be evaluated for specific applications, particularly in space-constrained designs.

Q: Are the Molex substitutes compatible with existing TE Connectivity MATE-N-LOK cable connectors?

A: Compatibility depends on the specific cable connector model. The substitute parts maintain the 3.00mm pitch and 11-position configuration, which are the primary mechanical parameters for mating. However, connector series-specific design features may affect compatibility. Verification with the cable connector manufacturer or technical documentation is necessary for applications requiring confirmed interchangeability.

Q: What is the advantage of ROHS3 compliance in the substitute parts?

A: ROHS3 compliance indicates conformance to Restriction of Hazardous Substances regulations, restricting lead, cadmium, mercury, and other hazardous materials. The original TE Connectivity part is non-compliant. For new product designs, regulatory requirements, or supply to regulated markets, the ROHS3-compliant Molex substitutes eliminate compliance barriers and reduce environmental impact.

Q: Which substitute part should be selected for automated pick-and-place assembly?

A: Molex 0436501121 and 0436501126 are supplied in Tape & Reel (TR) packaging, which is standard for automated surface mount assembly processes. These parts are optimized for high-volume production environments using pick-and-place equipment.

Q: Does the change from tin-lead to tin-only post finish affect solderability?

A: The original part specifies tin-lead post finish (100.0µin), while all substitutes specify tin-only post finish (100.0µin). Modern lead-free solder processes are compatible with tin-only finishes. For applications using legacy lead-containing solder, compatibility should be confirmed with soldering process specifications and the connector manufacturer.
