Key Parameters

Substitute Part Grouping Explanation

Substitution of the Molex 0022280021 is determined by strict alignment of the following electrical and mechanical parameters:

Critical Matching Parameters:

• Pitch - Mating: 0.100" (2.54mm)
• Number of Positions: 2
• Number of Rows: 1
• Contact Type: Male Pin
• Mounting Type: Through Hole
• Termination: Solder
• Shrouding: Shrouded - 1 Wall
• Contact Finish - Mating: Gold

Acceptable Variation Parameters:

• Insulation Material: Thermoplastic is functionally equivalent to Polyamide (PA), Nylon, Glass Filled for this application
• Contact Length - Post: Minor variations (0.120" to 0.140") are acceptable within standard PCB through-hole tolerances
• Insulation Height: Variations within 0.305" to 0.337" maintain mechanical compatibility

The TE Connectivity AMP Connectors part 3-641126-2 satisfies all critical matching parameters and acceptable variation criteria, establishing it as a direct functional equivalent.

Engineering Selection Recommendations

The TE Connectivity AMP Connectors 3-641126-2 is the designated equivalent for the obsolete Molex 0022280021 based on the following engineering criteria:

Product Status Alignment: The substitute part maintains active production status, ensuring long-term availability and supply chain continuity for applications currently using the Molex component.

Compliance & Certification: Both parts meet UL94 V-0 flammability requirements and maintain MSL 1 (Unlimited) moisture sensitivity ratings. The TE Connectivity part holds RoHS Compliance certification, meeting current regulatory standards for electronic components.

Mechanical & Electrical Compatibility: All critical parameters—pitch, position count, contact type, mounting method, and termination—are identical. Minor dimensional variations in contact post length and insulation height fall within acceptable tolerances for through-hole PCB assembly and do not compromise mechanical fit or electrical performance.

Series Compatibility: The TE Connectivity MTA-100 series provides direct functional replacement within the 2.54mm pitch connector ecosystem, supporting seamless integration into existing designs.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 3-641126-2 be used as a direct replacement for the Molex 0022280021 in existing designs?

A: Yes. Both parts share identical pitch (0.100" / 2.54mm), position count (2), contact type (Male Pin), mounting method (Through Hole), and termination (Solder). Mechanical dimensions are compatible within standard PCB assembly tolerances.

Q: What is the primary reason for substitution?

A: The Molex 0022280021 is classified as obsolete. The TE Connectivity 3-641126-2 is an active production equivalent that provides continuity for maintenance, repair, and new production requirements.

Q: Are there differences in insulation material between the two parts?

A: The Molex part uses Polyamide (PA), Nylon, Glass Filled insulation, while the TE Connectivity part uses Thermoplastic insulation. Both materials meet UL94 V-0 flammability requirements and are functionally equivalent for this connector application.

Q: Do both parts meet current regulatory compliance standards?
