TE Connectivity 1-1445100-2 Rectangular Connector Header Equivalent & Substitute Parts

Part Overview

The TE Connectivity 1-1445100-2 is a surface mount, right-angle rectangular connector header from the Micro MATE-N-LOK series. This 12-position connector operates as a board-to-cable/wire interface with a 0.118" (3.00mm) pitch and solder termination. The part is currently in active product status with 668 units in stock.

Identification of equivalent and substitute parts becomes necessary when the primary part reaches end-of-life status, inventory constraints occur, or design revisions require component verification. The 3-1445100-2 represents a direct substitute option, though it carries an obsolete product status designation.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for rectangular connector headers is determined by strict equivalence across the following critical parameters:

Mechanical Compatibility:

• Connector type (Header)
• Contact type (Male Pin)
• Number of positions (12)
• Number of rows (1)
• Pitch - mating (0.118" / 3.00mm)
• Mounting type (Surface Mount, Right Angle)
• Shrouding configuration (Shrouded - 4 Wall)

Electrical Compatibility:

• Voltage rating (250V)
• Operating temperature range (-40°C ~ 105°C)
• Contact material (Brass)
• Contact finish - mating (Gold)

Termination & Assembly:

• Termination method (Solder)
• Fastening type (Locking Ramp)
• Insulation material (Polyamide/Nylon)

The substitute part 3-1445100-2 maintains full equivalence across all mechanical, electrical, and termination parameters. The primary distinction is product status classification and contact finish post composition.

Engineering Selection Recommendations

Primary Selection: 1-1445100-2

The 1-1445100-2 is the recommended selection for new designs and ongoing production. This part maintains active product status with TE Connectivity, ensuring continued availability and manufacturer support. Current inventory of 668 units supports immediate procurement requirements.

Alternative Selection: 3-1445100-2

The 3-1445100-2 functions as a direct electrical and mechanical equivalent. However, this part carries obsolete product status designation, indicating discontinued manufacturer support and limited long-term availability. The contact finish post composition differs (Tin versus Tin-Lead), which does not affect functional compatibility but reflects manufacturing process changes.

The 3-1445100-2 carries RoHS Compliant certification, whereas the 1-1445100-2 lists RoHS status as not applicable. Both parts meet UL94 V-0 flammability requirements and operate across the identical temperature and voltage specifications.

Compliance Considerations:

For applications requiring RoHS compliance, the 3-1445100-2 provides explicit certification. The 1-1445100-2 RoHS status designation does not preclude use in RoHS-regulated applications; however, compliance verification through the manufacturer is recommended for regulated product categories.

Both parts carry Moisture Sensitivity Level 1 (Unlimited), indicating no special moisture handling requirements during storage or assembly.

Frequently Asked Questions (FAQ)

Q: Can the 3-1445100-2 be used as a direct replacement for the 1-1445100-2 in existing assemblies?

A: Yes. The 3-1445100-2 maintains full mechanical and electrical equivalence across all critical parameters including connector type, position count, pitch, mounting configuration, voltage rating, and operating temperature range. The contact finish post composition change (Tin versus Tin-Lead) does not affect functional compatibility.

Q: What is the significance of the product status difference between these parts?

A: The 1-1445100-2 is classified as Active, indicating ongoing manufacturer production and support. The 3-1445100-2 is classified as Obsolete, indicating discontinued production. For new designs, the active part ensures long-term availability and manufacturer technical support. The obsolete part may be used for legacy system maintenance where existing inventory exists.

Q: Are there differences in RoHS compliance between these parts?

A: The 3-1445100-2 carries explicit RoHS Compliant certification. The 1-1445100-2 lists RoHS status as not applicable. This distinction reflects different manufacturing batches or process generations. For applications subject to RoHS regulations, the 3-1445100-2 provides documented compliance. The 1-1445100-2 RoHS status does not indicate non-compliance; rather, it indicates the part was not evaluated under RoHS criteria.

Q: Do these connectors require special handling during assembly?

A: Both parts carry Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity precautions are required. Standard surface mount assembly processes apply. Solder termination follows conventional PCB assembly procedures for 0.118" (3.00mm) pitch connectors.

Q: What is the mating interface for these headers?

A: These are header connectors designed for board-to-cable/wire connections. The 12-position, 0.118" (3.00mm) pitch configuration mates with corresponding Micro MATE-N-LOK receptacle connectors from TE Connectivity. Connector pairing must maintain identical pitch and position count specifications.

Q: Can these parts be used interchangeably in high-temperature applications?

A: Both parts operate across the identical temperature range of -40°C to 105°C. Applications requiring operation beyond this range require alternative connector selection. The operating temperature specification is identical between the active and obsolete parts.

Q: What is the voltage rating limitation for these connectors?

A: Both parts carry a 250V voltage rating. Applications requiring higher voltage specifications require alternative connector selection from the Micro MATE-N-LOK series or other TE Connectivity rectangular connector families.
