Substitute Part Grouping Explanation

Substitution of the Molex 0022283237 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 with UL94 V-0 flammability rating and RoHS compliance

The Molex 0022280237 qualifies as a direct substitute based on matching all critical parameters. Both connectors share identical position count, pitch, mounting type, contact configuration, and insulation material specifications. The substitute part operates within the same electrical and mechanical envelope, ensuring board-level compatibility.

Parameter Comparison

Engineering Selection Recommendations

The Molex 0022280237 is the appropriate substitute for the obsolete Molex 0022283237. The substitute part maintains active product status, ensuring long-term availability and supply chain continuity. Both connectors satisfy identical electrical and mechanical requirements for board-to-board and cable interconnection applications.

The substitute part carries RoHS compliance certification and operates across the same application domains: automotive, medical, telecommunications, and general-purpose electronics. The operating temperature range of -40°C to 105°C and voltage rating of 600VAC/DC for the substitute part support the functional requirements of the original design.

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 connector interface level, as both designs maintain identical contact geometry, pitch, and mating characteristics.

Frequently Asked Questions (FAQ)

Q: Are the Molex 0022283237 and 0022280237 mechanically interchangeable?

A: Yes. Both connectors share identical position count (23), mating pitch (0.100"), contact geometry, and through-hole mounting configuration. The connectors occupy the same board footprint and mate with identical receptacle designs.

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

A: Push-pull fastening uses a mechanical latch mechanism for connector retention, while friction lock relies on contact pressure to maintain mated position. Both fastening types provide secure connection retention. The choice between them depends on application-specific requirements for connector removal frequency and handling procedures.

Q: Can the substitute part be used in automotive applications?

A: Yes. The Molex 0022280237 is rated for automotive applications and carries UL94 V-0 flammability certification, meeting automotive industry standards for connector reliability and safety.

Q: What is the significance of the insulation material difference?

A: The original part specifies glass-filled polyamide, while the substitute uses standard polyamide nylon. Both materials meet UL94 V-0 flammability requirements and provide equivalent mechanical and electrical insulation properties for the specified applications.

Q: Is the substitute part RoHS compliant?

A: Yes. The Molex 0022280237 carries RoHS compliance certification, meeting environmental and material restriction requirements for regulated markets.

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

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