Parameter Comparison

Engineering Selection Recommendations

The Molex 0022280273 is the manufacturer-recommended substitute for the obsolete Molex 0022283273. Both connectors maintain identical mechanical and electrical interface specifications, ensuring direct compatibility in through-hole PCB applications.

The substitute part offers the following advantages:

• Active Product Status: The 0022280273 is currently in active production, ensuring long-term availability and supply chain continuity.
• Enhanced Specifications: The substitute provides defined operating temperature range (-40°C ~ 105°C), voltage rating (600VAC/DC), and current rating specifications, whereas the original part does not specify these parameters.
• Compliance Alignment: Both parts maintain UL94 V-0 flammability rating and RoHS compliance, meeting regulatory requirements for automotive, medical, and telecommunications applications.
• Fastening Mechanism Difference: The substitute employs friction lock fastening instead of push-pull. This represents a functional design change that must be evaluated against application requirements.

Selection of the 0022280273 is appropriate for new designs and obsolescence mitigation strategies where the friction lock fastening mechanism is compatible with the intended application.

Frequently Asked Questions (FAQ)

Q: Are the 0022283273 and 0022280273 mechanically interchangeable?

A: Both connectors share identical mating pitch (0.100"), position count (27), contact dimensions, and insulation geometry. Mechanical interchangeability is confirmed for PCB mounting and mating interface. The fastening mechanism differs (push-pull versus friction lock), which may affect connector retention characteristics in the application.

Q: What is the significance of the series designation change from 42225 to 42227?

A: The series designation reflects the product line evolution within Molex's KK254 connector family. The 42227 series represents the active production variant with enhanced electrical specifications and current availability.

Q: Can the 0022280273 be used as a direct replacement in existing assemblies?

A: The 0022280273 provides electrical and mechanical compatibility for board-level connections. The friction lock fastening mechanism should be evaluated against the original push-pull design to ensure compatibility with mating connectors and application-specific retention requirements.

Q: What compliance certifications apply to both parts?

A: Both the 0022283273 and 0022280273 meet UL94 V-0 flammability requirements and RoHS compliance standards. The substitute part provides explicit operating temperature (-40°C ~ 105°C) and voltage rating (600VAC/DC) specifications suitable for automotive, medical, and telecommunications applications.

Q: Is the 0022280273 suitable for high-reliability applications?

A: Both connectors feature tin-plated square contacts with 100.0µin finish thickness, polyamide nylon insulation with glass reinforcement, and MSL 1 (unlimited) moisture sensitivity rating. The substitute's defined electrical specifications and active production status support deployment in automotive and medical applications where component traceability and long-term availability are required.
