Molex 0022032021 Equivalent & Substitute Parts

Part Overview

The Molex 0022032021 is an unshrouded rectangular connector header designed for through-hole mounting applications. This 2-position, single-row header operates at a 0.100" (2.54mm) pitch and features male pin contacts with tin plating. The connector is classified as Active product status and serves general purpose, automotive, medical, and telecommunications applications. Substitute parts are identified to provide alternative sourcing options when the primary part is unavailable or when design flexibility permits component interchange.

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0022032021 is determined by the following critical parameters:

  • Connector Type: Header
  • Contact Type: Male Pin
  • Pitch - Mating: 0.100" (2.54mm)
  • Number of Positions: 2
  • Number of Rows: 1
  • Mounting Type: Through Hole
  • Termination: Solder
  • Contact Finish - Mating: Tin
  • Shrouding: Unshrouded
  • Material Flammability Rating: UL94 V-0
  • RoHS Status: ROHS3 Compliant

The TE Connectivity AMP Connectors part number 3-644456-2 meets all critical substitution criteria. Both connectors share identical mating pitch, position count, row configuration, mounting method, and termination type. Both feature tin-plated male pin contacts, unshrouded design, UL94 V-0 flammability rating, and ROHS3 compliance. These alignments establish functional and regulatory equivalence for board-to-cable/wire applications.

Engineering Selection Recommendations

Both the Molex 0022032021 and TE Connectivity 3-644456-2 maintain Active product status and satisfy ROHS3 compliance and UL94 V-0 flammability requirements. The connectors are electrically and mechanically equivalent for applications requiring 2-position, 0.100" pitch through-hole header connections with tin-plated male pin contacts.

The TE Connectivity substitute provides specified operating temperature range (-55°C ~ 105°C) and voltage rating (250VAC), whereas the Molex part does not include these specifications in the provided data. Selection between these parts should account for application-specific thermal and voltage requirements when such parameters are critical to system design.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 3-644456-2 directly replace the Molex 0022032021 in existing designs?

A: Yes. Both connectors share identical mating pitch (0.100"), position count (2), row configuration (1), contact type (male pin), mounting method (through hole), and termination type (solder). The unshrouded design and tin-plated contact finish are identical. Both meet UL94 V-0 and ROHS3 requirements.

Q: What are the key differences between these two connectors?

A: The primary differences are insulation material (Polyamide/Nylon versus Thermoplastic), contact post length (0.135" versus 0.110"), overall contact length (0.560" versus 0.505"), and insulation height (0.130" versus 0.100"). The TE Connectivity part specifies operating temperature (-55°C ~ 105°C) and voltage rating (250VAC), while the Molex part does not provide these specifications.

Q: Are both connectors suitable for the same applications?

A: Both connectors are rated for general purpose applications. The Molex part lists automotive, medical, and telecommunications applications in addition to general purpose. Application suitability depends on specific thermal, voltage, and environmental requirements of the end system.

Q: What is the significance of the contact finish thickness difference?

A: The TE Connectivity part features 150.0µin (3.81µm) tin plating on both mating and post contacts, compared to 60.0µin (1.52µm) on the Molex part. Thicker plating provides enhanced corrosion resistance and extended contact life in demanding environments.

Q: Do both connectors have the same moisture sensitivity level?

A: Yes. Both connectors are classified as MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.
