Substitute Part Grouping Explanation

Substitution of the Molex 0022283344 is determined by strict equivalence across the following critical parameters:

• Connector Type & Configuration: Header, Breakaway design with male pin contacts
• Position Count & Pitch: 34 positions at 0.100" (2.54mm) mating pitch
• Mounting & Termination: Through-hole mounting with kinked pin solder termination
• Shrouding & Mechanical Form: Shrouded single-wall construction
• Contact Finish: Gold-plated mating surface with tin-plated post
• Insulation Material: Polyamide (PA) nylon, glass-filled construction
• Compliance: RoHS compliance and UL94 V-0 flammability rating

The Molex 0022280344 qualifies as a direct substitute based on matching all critical electrical and mechanical parameters while offering active product status and enhanced operational specifications.

Parameter Comparison

Engineering Selection Recommendations

The Molex 0022280344 is the direct substitute for the obsolete Molex 0022283344. Both components maintain identical electrical and mechanical specifications across all critical parameters including position count, pitch, contact geometry, termination method, and insulation material composition.

The 0022280344 offers the advantage of active product status, ensuring ongoing availability and manufacturing support. Both parts maintain equivalent RoHS compliance and UL94 V-0 flammability certification, suitable for automotive, medical, telecommunications, and general purpose applications.

The primary difference between the two parts is the fastening mechanism: the original part uses push-pull fastening, while the substitute employs friction lock fastening. This distinction does not affect electrical or mechanical compatibility in applications where the connector is soldered to a PCB and mated with a compatible receptacle.

Frequently Asked Questions (FAQ)

Q: Are the 0022283344 and 0022280344 electrically interchangeable?

A: Yes. Both connectors feature identical contact geometry, gold-plated mating surfaces, tin-plated posts, and insulation material composition. They are electrically equivalent for all applications within the specified pitch and position configuration.

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

A: Push-pull fastening uses a mechanical latch mechanism for mating and unmating. Friction lock fastening relies on contact pressure between mating surfaces. In PCB-soldered applications where the header remains permanently mounted, this distinction has no functional impact on connector performance.

Q: Can I use the 0022280344 as a direct replacement in existing designs?

A: Yes, provided the design does not depend on the specific push-pull fastening mechanism of the original part. The substitute maintains all electrical and mechanical specifications necessary for board-to-board or cable interconnection at 0.100" (2.54mm) pitch with 34 positions.

Q: Are both parts RoHS compliant?

A: Yes. The 0022283344 is ROHS3 compliant, and the 0022280344 is RoHS compliant. Both meet regulatory requirements for restricted substance elimination.

Q: What is the operating temperature range for these connectors?

A: The 0022280344 specifies an operating temperature range of -40°C to 105°C. The original part does not provide this specification in the available documentation.

Q: Are these connectors suitable for automotive applications?

A: Yes. Both parts are listed for automotive applications and maintain UL94 V-0 flammability certification, meeting automotive industry standards for connector reliability and safety.
