Key Parameters

Substitute Part Grouping Explanation

Substitution of the Molex 0022283293 is determined by strict equivalence across the following critical parameters:

• Connector Type & Configuration: Header, Breakaway design with male pin contacts
• Position Count & Pitch: 29 positions at 0.100" (2.54mm) mating pitch
• Mounting & Termination: Through-hole mounting with kinked pin solder termination
• Shrouding & Geometry: Single-wall shrouded design with matching insulation height (0.337"), contact lengths, and overall dimensions
• Material & Finish: Polyamide nylon insulation with tin-plated contacts
• Compliance: UL94 V-0 flammability rating and RoHS compliance

The substitute part Molex 0022280293 maintains full equivalence across all these parameters while offering active product status and expanded electrical specifications.

Parameter Comparison

Engineering Selection Recommendations

The Molex 0022280293 is the direct active equivalent for the obsolete Molex 0022283293. Both connectors share identical mechanical and electrical interface specifications, including position count, pitch, contact geometry, and mounting configuration. The substitute part maintains full compliance with UL94 V-0 flammability requirements and RoHS standards.

The primary distinction between the parts is product status: the 0022283293 is obsolete, while the 0022280293 is actively manufactured and supported. The substitute part provides documented operating temperature range (-40°C ~ 105°C) and electrical ratings (600VAC/DC) that were not specified for the original part. The fastening mechanism differs (Push-Pull versus Friction Lock), reflecting design evolution within the KK254 series.

For new designs or ongoing production requiring this connector type, the 0022280293 is the appropriate selection. For legacy system maintenance where the original part specification must be preserved, the 0022280293 provides functional and dimensional equivalence.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0022280293 directly replace the 0022283293 in existing assemblies?

A: Yes. Both connectors maintain identical mating pitch (0.100"), position count (29), contact geometry, and through-hole mounting configuration. Physical and electrical interface compatibility is maintained.

Q: What is the difference between Push-Pull and Friction Lock fastening?

A: Push-Pull fastening (0022283293) uses a mechanical latch mechanism for connector retention. Friction Lock fastening (0022280293) relies on contact pressure for retention. Both provide secure mating in their respective designs.

Q: Are there any compliance differences between the two parts?

A: Both parts meet UL94 V-0 flammability requirements and RoHS compliance standards. The 0022280293 provides explicit operating temperature (-40°C ~ 105°C) and voltage (600VAC/DC) specifications, while the 0022283293 does not document these parameters.

Q: Why is the 0022283293 listed as obsolete?

A: Product obsolescence reflects manufacturer discontinuation. The 0022280293 represents the active equivalent within the KK254 series and is the recommended selection for current procurement.

Q: Are the contact finishes identical?

A: Yes. Both parts feature tin-plated contacts with 100.0µin (2.54µm) finish thickness on both mating and post surfaces.

Q: What applications are these connectors suitable for?

A: Both connectors are specified for automotive, general purpose, medical, and telecommunications applications.
