Substitute Part Grouping Explanation

Substitution of the Molex 0022283231 is determined by strict alignment of the following electrical and mechanical parameters:

• Connector Type & Configuration: Header, Breakaway design with male pin contacts
• Position Count & Pitch: 23 positions at 0.100" (2.54mm) mating pitch
• Mounting & Termination: Through-hole solder termination
• Shrouding Design: Shrouded single-wall construction
• Contact Geometry: Square contact shape with specified mating and post lengths
• Material & Compliance: Polyamide insulation, UL94 V-0 flammability rating, RoHS compliance

The Molex 0022280231 qualifies as a direct substitute based on matching all critical parameters. Both connectors share identical position count, pitch, mounting type, shrouding configuration, contact geometry, and material specifications. The substitute part operates within the same electrical and mechanical envelope, ensuring board-level compatibility and functional equivalence.

Parameter Comparison

Engineering Selection Recommendations

The Molex 0022280231 is the appropriate substitute for the obsolete Molex 0022283231. The substitute part maintains active product status, ensuring long-term availability and supply chain continuity. Both connectors comply with RoHS regulations and carry UL94 V-0 flammability certification, meeting the same material and environmental standards.

The primary distinction between the parts is the fastening mechanism: the original part uses push-pull fastening, while the substitute employs friction lock fastening. This difference does not affect electrical or mechanical compatibility at the board interface level, as both designs accommodate the same contact geometry and mating pitch.

The substitute part provides documented operating temperature range (-40°C ~ 105°C) and voltage rating (600VAC/DC), specifications not explicitly provided for the original part. These ratings align with standard KK254 series performance parameters and support the same application domains: automotive, medical, telecommunications, and general-purpose industrial use.

Frequently Asked Questions (FAQ)

Q: Are the 0022283231 and 0022280231 mechanically interchangeable?

A: Yes. Both connectors share identical position count (23), mating pitch (0.100"), contact geometry (square shape), and overall dimensions. The through-hole mounting footprint and solder termination are identical, enabling direct board-level substitution.

Q: What is the difference between push-pull and friction lock fastening?

A: Push-pull fastening uses a mechanical latch mechanism for mated connector retention. Friction lock fastening relies on contact pressure and mechanical fit. Both methods secure the mated connection; the selection depends on application-specific requirements for mating force and unmating procedure.

Q: Does the substitute part support the same applications?

A: Yes. The 0022280231 is rated for automotive, medical, telecommunications, and general-purpose applications, matching the application scope of the original part.

Q: Are there RoHS compliance differences?

A: The original part carries ROHS3 Compliant status, while the substitute carries RoHS Compliant status. Both meet RoHS requirements; the designation difference reflects the specific RoHS directive version under which each part was certified.

Q: What is the moisture sensitivity level for both parts?

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

Q: Can I use the substitute part in existing designs without PCB modification?

A: Yes. The substitute part maintains identical through-hole mounting dimensions and solder pad requirements, requiring no PCB layout changes.
