TE Connectivity 350790-2 Rectangular Connector Header Equivalent & Substitute Parts

Part Overview

The TE Connectivity 350790-2 is a shrouded vertical rectangular connector header designed for through-hole mounting in board-to-cable/wire applications. This component features a 3-position configuration with 0.250" (6.35mm) pitch spacing and is part of the Universal MATE-N-LOK series. The part is currently classified as obsolete, making identification of equivalent and substitute components essential for ongoing design support and procurement planning. Active alternatives are available from both TE Connectivity and third-party manufacturers that maintain electrical and mechanical compatibility within specified parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TE Connectivity 350790-2 is determined by strict alignment of the following critical parameters:

Primary Matching Criteria:

• Connector type: Header
• Contact type: Male Pin
• Number of positions: 3
• Number of rows: 1
• Pitch - mating: 0.250" (6.35mm)
• Mounting type: Through Hole
• Shrouding: Shrouded - 4 Wall
• Termination: Solder
• Fastening type: Locking Ramp
• Style: Board to Cable/Wire

Secondary Compatibility Parameters:

• Insulation material: Polyamide (PA) or Nylon variants
• Contact shape: Circular
• Insulation height: 0.550" (13.97mm)
• Moisture sensitivity level: 1 (Unlimited)

The substitute parts identified maintain these core electrical and mechanical specifications. Variations in contact finish thickness, insulation color, and flammability ratings are noted where they occur, as these represent acceptable engineering trade-offs within the rectangular connector category.

TE Connectivity 350790-3 (Direct Substitute)

The 350790-3 is the primary equivalent for the obsolete 350790-2. Both components share identical electrical and mechanical specifications within the Universal MATE-N-LOK series. The 350790-3 maintains active product status and carries ROHS3 compliance certification, making it suitable for new designs and legacy system replacements. The component is available in bulk packaging and maintains full compatibility with existing board layouts and mating connectors designed for the 350790-2.

Molex 0367570022 (Similar Substitute)

The Molex 0367570022 provides functional equivalence with documented differences in specific parameters. This component maintains the same connector type, position count, pitch spacing, mounting method, and shrouding configuration. Key differences include:

• Contact length post: 0.169" (4.30mm) versus 0.215" (5.46mm) in the TE Connectivity parts
• Contact finish mating: Tin versus Gold
• Material flammability rating: UL94 V-2 versus UL94 V-0
• Insulation color: Natural versus White
• Expanded application scope: Automotive, General Purpose, Industrial

The Molex part is ROHS3 compliant and includes board guide and glow wire compliance features. Selection of this substitute requires verification that the reduced contact post length and alternative contact finish are compatible with the mating connector and circuit requirements.

Frequently Asked Questions (FAQ)

Q: Can the 350790-3 be used as a direct replacement for the 350790-2?

A: Yes. The 350790-3 maintains identical specifications for all critical electrical and mechanical parameters including connector type, position count, pitch spacing, mounting configuration, and shrouding. The primary difference is product status: the 350790-3 is active and ROHS3 compliant, while the 350790-2 is obsolete.

Q: What are the key differences between the TE Connectivity 350790-3 and the Molex 0367570022?

A: Both parts share the same connector type, position count, pitch spacing, mounting method, and shrouding. The Molex part differs in contact post length (0.169" versus 0.215"), contact finish mating surface (Tin versus Gold), material flammability rating (UL94 V-2 versus UL94 V-0), and insulation color (Natural versus White). The Molex part also includes board guide and glow wire compliance features.

Q: Does the contact post length difference in the Molex 0367570022 affect compatibility?

A: The contact post length difference must be evaluated against the specific mating connector and PCB design. The Molex part has a shorter post length (0.169" versus 0.215"), which may impact solder joint formation and mechanical engagement depending on the receiving connector cavity depth and PCB thickness.

Q: Are both substitute parts ROHS3 compliant?

A: Yes. Both the TE Connectivity 350790-3 and Molex 0367570022 carry ROHS3 compliance certification. The original 350790-2 is marked as not applicable for RoHS status due to its obsolete classification.

Q: What is the difference in material flammability ratings?

A: The TE Connectivity parts (350790-2 and 350790-3) carry UL94 V-0 rating, indicating superior flame resistance. The Molex 0367570022 carries UL94 V-2 rating. Selection between these ratings depends on application requirements and safety standards applicable to the end product.

Q: How do the contact finish specifications differ?

A: The TE Connectivity parts feature gold-plated mating contacts (30.0µin thickness) with tin-plated posts. The Molex part features tin-plated mating contacts (137.8µin thickness) with tin-plated posts. Gold plating provides superior corrosion resistance and lower contact resistance, while tin plating offers cost efficiency and adequate performance for general-purpose applications.

Q: What packaging options are available for these parts?

A: The TE Connectivity 350790-3 is supplied in bulk packaging. The Molex 0367570022 is supplied in tray packaging. Packaging selection may influence procurement logistics and handling procedures.

Q: Are these parts suitable for automotive applications?

A: The TE Connectivity parts are specified for general-purpose applications. The Molex 0367570022 is explicitly rated for automotive, general-purpose, and industrial applications, including glow wire compliance certification.
