TE Connectivity 1445100-4 Rectangular Connector Header Equivalent & Substitute Parts

Part Overview

The TE Connectivity 1445100-4 is a surface mount, right-angle rectangular connector header from the Micro MATE-N-LOK series. This 4-position connector operates at 250V with an operating temperature range of -40°C to 105°C and features gold-plated mating contacts with tin-lead post finishes. The connector is designed for board-to-cable/wire applications with solder termination and locking ramp fastening. The part is currently active in production. Equivalent and substitute parts are identified to provide alternative sourcing options when the primary part number is unavailable or when specific packaging or compliance requirements necessitate component substitution.

Key Parameters

Substitute Part Grouping Explanation

Substitution between the main part number 1445100-4 and the equivalent part 2-1445100-4 is based on identical electrical and mechanical parameters. Both parts share the same connector type, contact configuration, pitch, mounting style, shrouding design, termination method, voltage rating, and operating temperature range. The key parameters that determine substitutability are:

• Connector Type: Header
• Number of Positions: 4
• Pitch - Mating: 0.118" (3.00mm)
• Mounting Type: Surface Mount, Right Angle
• Shrouding: Shrouded - 4 Wall
• Termination: Solder
• Voltage Rating: 250V
• Operating Temperature: -40°C ~ 105°C
• Contact Finish - Mating: Gold

The primary difference between these parts is packaging format and RoHS compliance status. Part 1445100-4 is supplied in standard packaging with RoHS non-compliant status, while part 2-1445100-4 is supplied in Cut Tape (CT) packaging with ROHS3 compliance. Both parts are from the same manufacturer and series, ensuring functional and mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both part numbers 1445100-4 and 2-1445100-4 are functionally and mechanically equivalent for rectangular connector header applications. Selection between these parts is determined by specific project requirements:

Part 1445100-4 is appropriate for applications where RoHS compliance is not a requirement and standard packaging is acceptable. This part maintains the original tin-lead post finish specification.

Part 2-1445100-4 is appropriate for applications requiring ROHS3 compliance and for high-volume production environments where Cut Tape (CT) packaging provides automated assembly advantages. This part features a tin post finish without lead content, aligning with RoHS3 requirements.

Both parts are active products from TE Connectivity AMP Connectors and carry identical electrical ratings, operating temperature ranges, and mechanical specifications. The choice between them depends on regulatory compliance mandates, assembly process requirements, and packaging preferences rather than functional performance differences.

Frequently Asked Questions (FAQ)

Q: Are parts 1445100-4 and 2-1445100-4 electrically interchangeable?

A: Yes. Both parts have identical electrical specifications including 250V voltage rating, -40°C to 105°C operating temperature range, and gold-plated mating contacts with 30.0µin (0.76µm) thickness.

Q: What is the difference between the post finishes on these two parts?

A: Part 1445100-4 features tin-lead post finish, while part 2-1445100-4 features tin post finish. Both maintain the same 100.0µin (2.54µm) thickness. The tin-only finish on 2-1445100-4 supports ROHS3 compliance.

Q: Can I use part 2-1445100-4 in place of 1445100-4 in existing designs?

A: Yes, provided your application does not specifically require tin-lead post finish. The mechanical and electrical characteristics are identical. Verify that your assembly process is compatible with Cut Tape (CT) packaging if switching from standard packaging.

Q: What does the "2-" prefix in part number 2-1445100-4 indicate?

A: The "2-" prefix indicates a variant of the base product number 1445100. In this case, it denotes the ROHS3-compliant version supplied in Cut Tape packaging.

Q: Are both parts suitable for surface mount assembly?

A: Yes. Both parts are designed for surface mount, right-angle installation with solder termination and locking ramp fastening.

Q: What is the mating pitch for these connectors?

A: The mating pitch is 0.118" (3.00mm) for both parts, ensuring compatibility with corresponding receptacle connectors in the Micro MATE-N-LOK series.

Q: Do these parts require any special handling or storage conditions?

A: Both parts have Moisture Sensitivity Level (MSL) 1, indicating unlimited shelf life without special moisture control requirements.

Q: What is the shrouding configuration?

A: Both parts feature shrouded design with 4 walls, providing mechanical protection and polarization for the 4-position male pin header.
