Substitute Part Grouping Explanation

Substitution of the Molex 0022283256 is determined by strict equivalence across the following critical parameters:

• Connector type classification (Header, Breakaway)
• Contact type (Male Pin)
• Number of positions and row configuration (25 positions, 1 row)
• Mating pitch (0.100" / 2.54mm)
• Mounting method (Through Hole)
• Termination type (Solder)
• Shrouding configuration (Shrouded - 1 Wall)
• Contact finish specification (Tin)
• Insulation material family (Polyamide/Nylon)
• Flammability rating (UL94 V-0)

The Molex 0022280256 satisfies all substitution criteria as an active product within the same KK254 series family, offering identical mechanical and electrical interface specifications with enhanced product availability and ongoing manufacturer support.

Parameter Comparison

Engineering Selection Recommendations

The Molex 0022280256 is the direct active equivalent for the obsolete Molex 0022283256. Both components maintain identical mechanical interface specifications, contact geometry, and electrical characteristics across all critical dimensions and materials.

The substitute part carries active product status with full manufacturer support, ensuring long-term availability and supply chain continuity. Both components satisfy RoHS compliance requirements and UL94 V-0 flammability certification, meeting regulatory standards for automotive, medical, and telecommunications applications.

The transition from 0022283256 to 0022280256 introduces no functional or mechanical incompatibility. Fastening type differs between push-pull (original) and friction lock (substitute), representing an internal mechanism variation that does not affect connector mating or board-level integration.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0022280256 directly replace the 0022283256 in existing designs?

A: Yes. Both connectors share identical mating pitch (0.100" / 2.54mm), position count (25), contact geometry, and through-hole mounting specifications. No PCB redesign or mechanical modification is required.

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

A: Push-pull fastening uses a mechanical latch mechanism for connector retention. Friction lock relies on contact pressure for retention. Both methods secure the mated connector pair; the selection depends on application-specific retention requirements and user preference.

Q: Are there compatibility concerns with existing mating connectors?

A: No. The substitute part maintains identical contact length, pitch, and shrouding configuration. Existing mating connectors designed for the 0022283256 will mate with the 0022280256 without modification.

Q: Does the insulation material change affect performance?

A: The substitute uses polyamide nylon without glass filling, compared to glass-filled nylon in the original. Both materials meet UL94 V-0 flammability requirements and are suitable for the specified application range (automotive, medical, telecommunications, general purpose).

Q: What is the inventory status for the substitute part?

A: The Molex 0022280256 is in active production with 842 pieces available in new original stock, providing reliable procurement availability compared to the obsolete 0022283256.

Q: Are both parts RoHS compliant?

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