TE Connectivity 1445093-3 Rectangular Connector Header Equivalent & Substitute Parts

Part Overview

The TE Connectivity 1445093-3 is a vertical rectangular connector header from the Micro MATE-N-LOK series. This through-hole mounted connector features 3 positions with 0.118" (3.00mm) pitch spacing and is designed for board-to-cable/wire applications. The connector is actively manufactured and maintains 1031 pieces in current inventory stock.

Substitute parts are identified when equivalent electrical and mechanical parameters are maintained across connector specifications. Alternative part numbers may be necessary due to packaging availability, compliance status differences, or inventory requirements while preserving functional compatibility in target applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution between TE Connectivity 1445093-3 and 2-1445093-3 is based on electrical and mechanical parameter equivalence. Both parts maintain identical specifications across the following critical parameters:

Electrical Parameters:

• Voltage Rating: 250V
• Operating Temperature Range: -40°C ~ 105°C
• Contact Material: Brass with gold mating finish (30.0µin / 0.76µm thickness)

Mechanical Parameters:

• Connector Type: Header with male pin contacts
• Number of Positions: 3
• Pitch - Mating: 0.118" (3.00mm)
• Mounting Type: Through Hole
• Shrouding: Shrouded - 4 Wall
• Insulation Material: Polyamide (PA), Nylon
• Insulation Height: 0.364" (9.25mm)
• Contact Shape: Square
• Fastening Type: Locking Ramp
• Features: Board Guide

Functional Parameters:

• Style: Board to Cable/Wire
• Termination: Press-Fit, Solder
• Number of Positions Loaded: All
• Material Flammability Rating: UL94 V-0

The primary difference between these parts is packaging format and post-contact finish composition, with 2-1445093-3 supplied in tray packaging and featuring tin post finish versus tin-lead post finish on 1445093-3.

Parameter Comparison

Engineering Selection Recommendations

Both 1445093-3 and 2-1445093-3 are active products from TE Connectivity and maintain full electrical and mechanical compatibility for general purpose board-to-cable/wire connector applications. Selection between these parts is determined by specific application requirements:

1445093-3 Selection Criteria:

• Applications requiring RoHS non-compliant components
• Tin-lead post finish specification
• Bulk packaging format preference
• Existing designs with tin-lead solder compatibility

2-1445093-3 Selection Criteria:

• Applications requiring RoHS compliance
• Tin post finish specification
• Tray packaging format requirement
• Lead-free solder process compatibility
• Higher inventory availability (13022 pieces versus 1031 pieces)

Both parts maintain identical electrical performance across the 250V voltage rating and -40°C to 105°C operating temperature range. The UL94 V-0 flammability rating is consistent across both variants. The primary technical distinction is the post-contact finish composition and RoHS compliance status, which affects solder process selection and regulatory requirements rather than functional connector performance.

Frequently Asked Questions (FAQ)

Q: Are 1445093-3 and 2-1445093-3 electrically interchangeable?

A: Yes. Both parts maintain identical electrical specifications including 250V voltage rating, -40°C to 105°C operating temperature range, and gold-plated mating contacts with 30.0µin thickness. Electrical performance is equivalent across all general purpose applications.

Q: What is the difference between tin-lead and tin post finishes?

A: The post finish refers to the plating on the solder tail of the connector. 1445093-3 features tin-lead post finish, while 2-1445093-3 features tin post finish. This distinction affects solder process compatibility and regulatory compliance. Tin-lead finishes are used in traditional solder processes, while tin finishes support lead-free solder processes.

Q: Why does 2-1445093-3 have RoHS compliance while 1445093-3 does not?

A: RoHS compliance is determined by the absence of restricted substances including lead. The tin-lead post finish on 1445093-3 contains lead, making it RoHS non-compliant. The tin post finish on 2-1445093-3 is lead-free, enabling RoHS compliance.

Q: Are the mechanical dimensions identical between these parts?

A: Yes. Both parts share identical mechanical specifications including 3-position configuration, 0.118" (3.00mm) pitch spacing, 0.125" (3.18mm) post length, 0.364" (9.25mm) insulation height, and shrouded 4-wall design. Through-hole mounting and board guide features are identical.

Q: What is the significance of packaging differences?

A: 1445093-3 is supplied in bulk packaging, while 2-1445093-3 is supplied in tray packaging. Packaging format affects handling, storage, and automated assembly processes but does not impact connector functionality or electrical performance.

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

A: Both parts are rated for operating temperatures from -40°C to 105°C. Applications requiring operation outside this range require alternative connector selection.

Q: Are both parts currently in production?

A: Yes. Both 1445093-3 and 2-1445093-3 maintain active product status with TE Connectivity. 2-1445093-3 has significantly higher inventory availability at 13022 pieces compared to 1031 pieces for 1445093-3.

Q: What is the current rating for these connectors?

A: Current rating varies by wire gauge. The connector specifications do not define a fixed amperage rating independent of the wire gauge used in the application.

Q: Are these connectors suitable for general purpose applications?

A: Yes. Both parts are designated for general purpose applications and maintain the necessary certifications including UL94 V-0 flammability rating and MSL 1 moisture sensitivity level for standard industrial and commercial use.
