Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 1445058-3 is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Connector Type: Header
• Contact Type: Male Pin
• Pitch - Mating: 0.118" (3.00mm)
• Number of Positions: 3
• Number of Rows: 1
• Mounting Type: Surface Mount, Right Angle
• Shrouding: Shrouded - 4 Wall
• Termination: Solder
• Fastening Type: Locking Ramp
• Contact Material: Brass
• Flammability Rating: UL94 V-0

All four Molex substitute parts (0436500305, 0436500309, 0436500310, 0436500311) satisfy these mandatory parameters. The Molex Micro-Fit 3.0 43650 series provides functional equivalence through identical mating pitch, position count, shrouding configuration, and fastening mechanism. Variations in contact finish composition and thickness do not affect core electrical or mechanical compatibility for general-purpose applications.

Parameter Comparison

Engineering Selection Recommendations

For Surface Mount Applications:

Molex 0436500309, 0436500310, and 0436500311 are direct functional equivalents for surface mount board assembly. All three parts are active products with ROHS3 compliance and REACH unaffected status, providing regulatory advantage over the obsolete TE Connectivity part. Selection among these three surface mount variants depends on contact finish requirements:

• Molex 0436500309: Tin mating finish, 60.0µin thickness
• Molex 0436500310: Gold mating finish, 15.0µin thickness
• Molex 0436500311: Gold mating finish, 30.0µin thickness

For Through Hole Applications:

Molex 0436500305 provides equivalent functionality for through-hole mounting applications. This part maintains all critical electrical and mechanical parameters while offering active product status and full regulatory compliance.

All substitute parts maintain the 3.00mm mating pitch, 3-position configuration, shrouded 4-wall construction, and locking ramp fastening mechanism required for direct replacement in existing connector systems.

Frequently Asked Questions (FAQ)

Q: Can Molex 0436500305 replace the TE Connectivity 1445058-3 in a surface mount application?

A: No. Molex 0436500305 is configured for through-hole mounting, while the TE Connectivity 1445058-3 is surface mount. For surface mount applications, use Molex 0436500309, 0436500310, or 0436500311.

Q: What is the difference between Molex 0436500309, 0436500310, and 0436500311?

A: All three parts are surface mount headers with identical mechanical and electrical specifications. The differences are in contact finish composition and thickness: 0436500309 has tin finish at 60.0µin, while 0436500310 and 0436500311 have gold finish at 15.0µin and 30.0µin respectively. These variations do not affect core connector functionality for general-purpose applications.

Q: Are the Molex substitutes compatible with existing TE Connectivity mating connectors?

A: Compatibility depends on the mating connector design. Both the TE Connectivity Micro MATE-N-LOK series and Molex Micro-Fit 3.0 series share the same 3.00mm mating pitch, 3-position configuration, and shrouded 4-wall construction. Verify mating connector specifications to confirm compatibility.

Q: What is the advantage of the Molex parts over the TE Connectivity 1445058-3?

A: The Molex substitute parts are active products with ROHS3 compliance and REACH unaffected status, whereas the TE Connectivity 1445058-3 is obsolete and RoHS non-compliant. Active product status ensures continued availability and manufacturing support.

Q: Does the insulation material difference affect performance?

A: The TE Connectivity 1445058-3 uses Polyamide (PA) nylon insulation, while Molex substitutes use Liquid Crystal Polymer (LCP) glass-filled insulation. Both materials meet UL94 V-0 flammability requirements and maintain equivalent electrical performance for general-purpose applications.

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

A: Molex 0436500305 is supplied in Tray packaging. Molex 0436500309, 0436500310, and 0436500311 are supplied in Tape & Reel (TR) packaging, suitable for automated assembly processes.
