Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete Molex 0349600300 is determined by strict alignment of the following critical parameters:

Substitution Criteria:

• Manufacturer Series Compatibility: Both parts must belong to the Molex MINI50 series (Base Product Number 034960)
• Connector Type Classification: Header configuration with identical functional purpose
• Electrical Specifications: Matching pitch (0.079" / 2.00mm), position count (102), and row configuration (3 rows)
• Regulatory Compliance: RoHS Compliant status and identical ECCN/HTSUS classifications
• Moisture Sensitivity: MSL rating of 1 or lower
• Mechanical Interface: Board-to-cable/wire connectivity with compatible mounting and termination methods

The substitute part Molex 0349600315 satisfies all substitution criteria through identical series designation, electrical configuration, and regulatory compliance status. The primary distinction is the transition from obsolete to active product status, enabling continued component availability.

5. Inventory Availability: The substitute part demonstrates superior inventory availability (802 Pcs) compared to the main part (684 Pcs), reducing procurement lead times and supply chain risk.

Frequently Asked Questions (FAQ)

Q: Why is the Molex 0349600300 classified as obsolete?

A: The 0349600300 has reached end-of-life status within Molex's product portfolio. The manufacturer has transitioned this connector to the active equivalent 0349600315, which provides identical electrical and mechanical functionality within the MINI50 series.

Q: Are the 0349600300 and 0349600315 electrically interchangeable?

A: Yes. Both parts are configured for 102-position, 3-row rectangular connector applications with 0.079" (2.00mm) mating pitch. The electrical specifications are identical, supporting direct substitution in board-to-cable/wire connectivity applications.

Q: What is the primary mechanical difference between these parts?

A: The 0349600315 is specified as a Through Hole, Right Angle header with breakaway capability, whereas the 0349600300 documentation does not explicitly detail these mounting characteristics. Both parts function as connector headers within the MINI50 series.

Q: Does the substitute part maintain RoHS compliance?

A: Yes. The 0349600315 is part of the Molex MINI50 series, which maintains RoHS Compliant status consistent with the original 0349600300.

Q: Are there any moisture sensitivity differences between the parts?

A: The 0349600300 specifies MSL 1 (Unlimited). The 0349600315 does not explicitly state MSL rating in the provided documentation; however, as a component within the same MINI50 series, equivalent moisture sensitivity characteristics are expected.

Q: What is the contact material and finish specification?

A: The 0349600315 specifies brass contact material with tin plating on both mating and post surfaces. These specifications are standard for the MINI50 series rectangular connectors.

Q: What operating temperature range does the substitute part support?

A: The 0349600315 operates across the temperature range of -40°C to 105°C, supporting industrial and commercial applications.

Q: Is the voltage rating identical between the two parts?

A: The 0349600315 specifies a 14VDC voltage rating. The 0349600300 voltage rating is not provided in the available documentation.

Q: Can I use existing inventory of the 0349600300 alongside new purchases of the 0349600315?

A: Yes. Both parts are electrically and mechanically compatible within the MINI50 series. Existing inventory of the 0349600300 can be utilized concurrently with new procurement of the 0349600315 for equivalent applications.

Q: What is the fastening mechanism for the substitute part?

A: The 0349600315 employs a latch holder fastening type, providing secure connector retention in board-to-cable/wire assemblies.
