Key Parameters

Substitute Part Grouping Explanation

Substitution of rectangular connectors is determined by strict alignment of electrical and mechanical parameters. The following criteria establish compatibility for the 1445056-4:

Primary Substitution Criteria:

• Connector type (Header)
• Contact type (Male Pin)
• Pitch - mating (0.118" / 3.00mm)
• Number of positions (4)
• Number of rows (1)
• Mounting type (Surface Mount, Right Angle)
• Shrouding configuration (Shrouded - 4 Wall)
• Termination method (Solder)
• Fastening type (Locking Ramp)
• Voltage rating (250V minimum)
• Operating temperature range (-40°C ~ 105°C minimum)
• Material flammability rating (UL94 V-0)

Secondary Considerations:

• Contact finish composition and thickness
• Insulation material and height
• Product status and compliance certifications
• Packaging format

Parts meeting all primary criteria are classified as direct equivalents. Parts meeting primary criteria with variations in secondary parameters are classified as functional substitutes.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent - TE Connectivity 2-1445056-4:

The 2-1445056-4 is the direct equivalent replacement for the obsolete 1445056-4. Both components share identical electrical and mechanical specifications across all primary substitution criteria. The 2-1445056-4 carries active product status and RoHS Compliant certification, providing superior compliance posture for new designs and ongoing production. The contact finish differs from Tin-Lead to Tin, reflecting modern manufacturing standards. This part is the preferred selection for direct replacement applications.

Functional Substitute - Molex 0436500409:

The Molex 0436500409 serves as a functional substitute when TE Connectivity parts are unavailable. This component meets all primary electrical and mechanical criteria, including connector type, pitch, position count, mounting configuration, and shrouding design. The 0436500409 features Liquid Crystal Polymer insulation material with increased insulation height (0.172" versus 0.152"), providing enhanced mechanical robustness. Contact finish thickness is reduced to 60.0µin. The part carries ROHS3 Compliant and REACH Unaffected certifications. Voltage and operating temperature ratings are not specified in available documentation. This substitute is suitable for applications where mechanical durability and advanced material properties are beneficial.

Frequently Asked Questions (FAQ)

Q: Can the 2-1445056-4 be used as a direct replacement for the 1445056-4?

A: Yes. The 2-1445056-4 is a direct equivalent with identical electrical and mechanical specifications. The primary difference is product status (Active versus Obsolete) and compliance certifications (RoHS Compliant). The contact finish composition has been updated from Tin-Lead to Tin, reflecting current manufacturing standards.

Q: What are the key differences between the TE Connectivity 2-1445056-4 and the Molex 0436500409?

A: Both parts share identical pitch (3.00mm), position count (4), mounting type (Surface Mount, Right Angle), and shrouding configuration. The Molex part features Liquid Crystal Polymer insulation with increased height (0.172" versus 0.152"), reduced contact finish thickness (60.0µin versus 100.0µin), and belongs to the Micro-Fit 3.0 series rather than Micro MATE-N-LOK. Voltage and operating temperature specifications are not provided for the Molex part.

Q: Are there packaging differences between these parts?

A: The main part 1445056-4 does not specify packaging format. Both substitute parts are supplied in Tape & Reel (TR) format, which is standard for surface mount components and suitable for automated assembly processes.

Q: What compliance certifications apply to each part?

A: The 1445056-4 carries UL94 V-0 flammability rating and MSL 1 (Unlimited) moisture sensitivity. The 2-1445056-4 adds RoHS Compliant certification. The Molex 0436500409 carries UL94 V-0, ROHS3 Compliant, and REACH Unaffected certifications.

Q: Can the Molex 0436500409 be used in applications requiring specific voltage and temperature ratings?

A: The Molex 0436500409 does not provide documented voltage and operating temperature specifications. The TE Connectivity parts specify 250V rating and -40°C ~ 105°C operating range. Confirmation of Molex part ratings is required before selection for applications with defined electrical or thermal requirements.

Q: What is the significance of the contact finish change from Tin-Lead to Tin?

A: The transition from Tin-Lead to Tin reflects compliance with lead-free manufacturing standards. Both finishes provide equivalent electrical performance and corrosion resistance. The Tin finish in the 2-1445056-4 is applied at 100.0µin thickness, matching the original specification.

Q: Are these parts suitable for medical, military, or telecommunications applications?

A: The TE Connectivity parts are specified for general purpose applications. The Molex 0436500409 is rated for general purpose, medical, military, and telecommunications applications, indicating broader application scope and potentially enhanced qualification testing.
