Engineering Selection Recommendations

Primary Substitute: Molex 0349600232

The Molex 0349600232 is the manufacturer-recommended substitute for the obsolete 0349600231. Selection of this part is based on the following engineering criteria:

Product Status Transition: The 0349600232 holds Active product status, ensuring long-term availability, ongoing manufacturing support, and compliance with current supply chain requirements. The 0349600231 is classified as Obsolete, presenting procurement risk and limiting future sourcing options.

Regulatory and Compliance Alignment: Both parts share identical ECCN (EAR99) and HTSUS (8536.69.4040) classifications, confirming equivalent export control and tariff treatment. This alignment eliminates compliance complications during component substitution.

Electrical and Mechanical Compatibility: The substitute part maintains all critical interface parameters: 72-position configuration, 0.079" (2.00mm) mating pitch, 14VDC voltage rating, and -40°C to 105°C operating temperature range. These specifications ensure functional equivalence in existing circuit designs without modification.

Manufacturing and Assembly Compatibility: Both parts employ solder termination and through-hole, right-angle mounting, maintaining compatibility with existing PCB layouts and assembly processes.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0349600232 be used as a direct replacement for the 0349600231 in existing designs?

A: Yes. The 0349600232 maintains identical electrical specifications (72 positions, 0.079" pitch, 14VDC rating), mechanical configuration (through-hole, right-angle mounting), and termination method (solder). No design modifications are required for substitution.

Q: What is the primary reason for substituting the 0349600231?

A: The 0349600231 is classified as Obsolete, which restricts procurement availability and manufacturing support. The 0349600232 holds Active status, ensuring reliable long-term sourcing and compliance with current supply chain standards.

Q: Are there differences in the connector type between these parts?

A: The 0349600231 is specified as a connector header position. The 0349600232 is specified as a Header with Breakaway configuration. Both function as headers within the MINI50 series and maintain compatible electrical and mechanical interfaces.

Q: Do these parts have the same regulatory classifications?

A: Yes. Both parts share identical ECCN (EAR99) and HTSUS (8536.69.4040) codes, confirming equivalent export control and tariff treatment.

Q: What is the operating temperature range for the substitute part?

A: The Molex 0349600232 operates across -40°C to 105°C, providing thermal performance suitable for industrial and commercial applications.

Q: Are there inventory considerations when transitioning from the 0349600231 to the 0349600232?

A: The 0349600231 currently has 738 pieces in stock as new original inventory. The 0349600232 has 929 pieces available. Transition planning should account for existing inventory levels and procurement lead times for the active substitute.

Q: What is the contact configuration of the substitute part?

A: The 0349600232 features male blade and male pin contacts with tin plating on both mating and post surfaces. Contacts are constructed from brass with an insulation height of 0.654" (16.61mm).

Q: Is the substitute part suitable for board-to-cable/wire applications?

A: Yes. The 0349600232 is classified as a board-to-cable/wire connector with shrouded 4-wall design and board guide features, maintaining compatibility with the original application context.
