Key Parameters

Substitute Part Grouping Explanation

Substitution of the Molex 0022283261 is determined by strict alignment of the following electrical and mechanical parameters:

• Connector type (Header, Breakaway)
• Contact type (Male Pin)
• Number of positions (26)
• Number of rows (1)
• Pitch - mating (0.100" / 2.54mm)
• Mounting type (Through Hole)
• Termination method (Solder)
• Shrouding configuration (Shrouded - 1 Wall)
• Contact finish - mating (Gold)
• Contact finish - post (Tin)
• Insulation material (Polyamide/Nylon, Glass Filled)
• Material flammability rating (UL94 V-0)

The Molex 0022280261 qualifies as a direct substitute based on full alignment with these core parameters. The substitute part maintains identical mechanical and electrical interface specifications while offering active product status and enhanced operational specifications.

Engineering Selection Recommendations

The Molex 0022280261 is the qualified substitute for the obsolete Molex 0022283261. Selection is based on the following engineering criteria:

Product Status: The substitute part maintains active product status, ensuring long-term availability and supply chain continuity. The main part is classified as obsolete, necessitating transition to an active equivalent.

Compliance & Certifications: Both parts maintain identical compliance profiles with UL94 V-0 material flammability rating, RoHS compliance, and EAR99 export classification. Moisture sensitivity level remains at MSL 1 (Unlimited) for both parts.

Mechanical & Electrical Interface: The substitute part preserves all critical interface parameters including 26-position configuration, 0.100" (2.54mm) pitch, through-hole mounting, solder termination, and gold-plated mating contacts. Physical dimensions and contact geometry remain unchanged.

Operational Specifications: The substitute part provides defined operating temperature range (-40°C ~ 105°C) and voltage rating (600VAC/DC), specifications not provided for the main part. These ratings support the connector's application in automotive, general purpose, medical, and telecommunications environments.

Fastening Mechanism Difference: The substitute part employs friction lock fastening in place of push-pull fastening. This represents a functional change in mating mechanism that must be evaluated against specific application requirements and mating connector specifications.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0022280261 directly replace the 0022283261 in existing designs?

A: The 0022280261 maintains identical mechanical and electrical interface specifications, including pitch, position count, contact geometry, and termination method. However, the fastening mechanism differs (friction lock versus push-pull). Compatibility depends on whether the mating connector accommodates the friction lock mechanism. Physical board layout and connector orientation remain compatible.

Q: What is the significance of the fastening type change from push-pull to friction lock?

A: Fastening type determines the mating and unmating force characteristics and the mechanical interface with the corresponding receptacle connector. Push-pull fastening uses a latch mechanism, while friction lock relies on contact pressure. The mating connector must be designed to accommodate the specific fastening type. Verify that the receptacle connector in your application supports friction lock engagement.

Q: Are there any compliance or regulatory differences between these parts?

A: Both parts maintain identical compliance certifications including UL94 V-0 flammability rating, RoHS compliance, and EAR99 export classification. Moisture sensitivity level is MSL 1 (Unlimited) for both parts. No regulatory or compliance barriers exist for substitution.

Q: What operational temperature and voltage specifications apply to the substitute part?

A: The Molex 0022280261 operates across -40°C to 105°C and supports 600VAC/DC voltage rating. These specifications support applications in automotive, general purpose, medical, and telecommunications environments. The main part does not provide these specifications in available documentation.

Q: Are the physical dimensions identical between the two parts?

A: Yes. Contact length (mating and post), overall contact length, insulation height, and all other dimensional parameters remain identical. Board layout and mechanical mounting requirements are unchanged.

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

A: The Molex 0022280261 maintains 711 pieces in new original stock, supporting immediate procurement. The main part has 979 pieces available but is classified as obsolete, indicating no future production.
