Molex 0022285203 Rectangular Connector Header - Equivalent & Substitute Parts

Part Overview

The Molex 0022285203 is an active-status vertical rectangular connector header designed for through-hole mounting applications. This 20-position, single-row connector operates at a 0.100" (2.54mm) pitch and features male pins with kinked solder termination. The component serves board-to-board and cable interconnection requirements across automotive, medical, telecommunications, and general-purpose applications. Equivalent parts are identified to provide alternative sourcing options while maintaining electrical and mechanical compatibility within specified parameter tolerances.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0022285203 is determined by the following critical parameters:

• Pitch - Mating: 0.100" (2.54mm) — must match exactly for mechanical alignment
• Number of Positions: 20 — must match for circuit connectivity
• Contact Type: Male Pin — must match for mating interface
• Mounting Type: Through Hole — must match for PCB assembly compatibility
• Connector Type: Header configuration — must support board-to-board or cable interconnection
• Shrouding: Unsshrouded — must match for physical fit
• Material Flammability Rating: UL94 V-0 — must meet or exceed for safety compliance
• RoHS Status: ROHS3 Compliant — must maintain regulatory compliance

The Preci-Dip 350-80-120-00-001101 qualifies as a direct substitute based on matching all critical parameters. Variations in contact finish (gold vs. tin), contact shape (square vs. circular), insulation material composition, and overall contact length remain within acceptable tolerances for equivalent electrical and mechanical performance in standard applications.

Parameter Comparison

Engineering Selection Recommendations

Both the Molex 0022285203 and Preci-Dip 350-80-120-00-001101 maintain active product status and ROHS3 compliance, ensuring continued availability and regulatory alignment. The Preci-Dip substitute provides documented operating temperature range (-55°C ~ 125°C) and electrical ratings (3A, 150VDC), which the Molex specification does not explicitly state. Selection between these parts should be based on application-specific requirements for contact finish preference (gold vs. tin), insulation material compatibility, and documented thermal or electrical performance criteria. Both components satisfy UL94 V-0 flammability requirements and unlimited moisture sensitivity classification, supporting deployment in automotive, medical, and telecommunications environments.

Frequently Asked Questions (FAQ)

Q: Can the Preci-Dip 350-80-120-00-001101 directly replace the Molex 0022285203 in existing designs?

A: Yes, provided the application does not require specific contact finish properties. The Preci-Dip substitute matches all critical mechanical and electrical parameters: 20-position, 0.100" pitch, male pin configuration, through-hole mounting, unshrouded design, and UL94 V-0 flammability rating. The primary difference is contact finish material (tin vs. gold), which may affect contact resistance and corrosion resistance in specific environmental conditions.

Q: What is the significance of the contact finish difference between these parts?

A: The Molex part features gold-plated mating contacts, while the Preci-Dip substitute uses tin finish. Gold provides superior corrosion resistance and lower contact resistance over extended service life. Tin finish is suitable for standard applications but may exhibit higher contact resistance and oxidation in high-humidity or corrosive environments. Application requirements should determine which finish is appropriate.

Q: Are there differences in insulation material that affect performance?

A: The Molex part uses polyamide (PA) nylon with glass filler, while the Preci-Dip substitute uses polycyclohexylenedimethylene terephthalate (PCT) polyester with glass filler. Both materials achieve UL94 V-0 flammability rating. PCT polyester typically offers superior dimensional stability and moisture resistance compared to polyamide. Material selection should align with application temperature cycling and humidity exposure requirements.

Q: Does the Preci-Dip part support cable interconnection like the Molex breakaway header?

A: The Preci-Dip specification lists "Board to Board" style, while the Molex part supports "Board to Board or Cable" applications. The Molex breakaway feature may provide additional flexibility for cable assembly configurations. Verify cable compatibility requirements before substitution if cable interconnection is a design requirement.

Q: What compliance certifications apply to both parts?

A: Both parts are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99 for export purposes. Both maintain Moisture Sensitivity Level 1 (unlimited), indicating no special moisture handling requirements during storage or assembly. These certifications ensure regulatory alignment for automotive, medical, and telecommunications applications.
