Key Parameters

Substitute Part Grouping Explanation

Substitution of the 146742-1 is determined by strict alignment of the following critical parameters:

Mechanical Compatibility:

• Connector type (Receptacle)
• Contact type (Female Socket)
• Number of positions (10)
• Pitch spacing (0.100" / 2.54mm)
• Row configuration (2 rows at 0.100" spacing)
• Mounting method (Through Hole, Right Angle)

Electrical & Material Compatibility:

• Contact material (Phosphor Bronze)
• Insulation material (Polyester, Glass Filled)
• Fastening mechanism (Push-Pull)
• Operating temperature range compatibility

Contact Finish Considerations: The 146742-1 specifies tin-lead contact finish. Substitute parts with tin-only finish remain functionally compatible for board-to-board applications where the mating connector accommodates this variation.

The Molex 0901522110 meets all mechanical and material requirements and is classified as an active product with current manufacturing support.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The 146742-1 is obsolete and no longer manufactured. The Molex 0901522110 is an active product with current manufacturing support, ensuring long-term component availability for ongoing production and maintenance requirements.

Compliance & Regulatory Status: The 146742-1 is RoHS non-compliant. The Molex 0901522110 is ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for new designs and applications subject to environmental compliance mandates.

Mechanical & Electrical Compatibility: Both connectors share identical mechanical specifications for pitch, row spacing, mounting orientation, and contact configuration. The phosphor bronze contact material and polyester glass-filled insulation are consistent across both parts. The push-pull fastening mechanism is identical.

Operating Temperature Range: The 146742-1 operates from -65°C to 105°C. The Molex 0901522110 operates from -55°C to 105°C. For applications requiring operation below -55°C, the 146742-1 specifications must be maintained. For standard industrial and commercial temperature ranges, the Molex substitute is suitable.

Contact Finish Differences: The 146742-1 specifies tin-lead finish at 100.0µin thickness. The Molex 0901522110 specifies tin-only finish at 40.0µin thickness. Both finishes are compatible with standard PCB soldering processes and provide equivalent electrical performance in board-to-board applications.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0901522110 directly replace the TE Connectivity 146742-1 in existing applications?

A: The Molex 0901522110 is mechanically and electrically compatible with the 146742-1 for board-to-board connector applications. Both connectors share identical pitch, row spacing, mounting type, and contact configuration. The primary consideration is the operating temperature range: the Molex part operates from -55°C minimum, while the original part operates from -65°C minimum. For applications requiring operation below -55°C, the original specification must be maintained.

Q: What is the difference between tin-lead and tin contact finishes?

A: Both tin-lead and tin finishes provide equivalent electrical conductivity and solderability for PCB assembly. The tin-lead finish on the 146742-1 is a legacy specification. The tin-only finish on the Molex 0901522110 is the current industry standard and is fully compatible with modern lead-free soldering processes. The contact finish thickness difference (100.0µin versus 40.0µin) does not affect functional performance in standard applications.

Q: Are there packaging differences between these connectors?

A: The 146742-1 packaging is not specified in the available data. The Molex 0901522110 is supplied in tube packaging. Packaging format does not affect connector performance or compatibility; it only impacts handling, storage, and logistics considerations.

Q: What is the significance of the RoHS compliance difference?

A: The 146742-1 is RoHS non-compliant, reflecting its obsolete status and legacy design. The Molex 0901522110 is ROHS3 compliant, meeting current environmental regulations. For new designs, production systems subject to RoHS requirements, or applications in regulated industries, the Molex substitute is the appropriate selection.

Q: Are the mechanical dimensions identical between these connectors?

A: The connectors share the same pitch (0.100"), row spacing (0.100"), and mounting configuration (through-hole, right-angle). Minor dimensional variations exist: insulation height differs by 0.008" (0.20mm), and contact post length differs by 0.001" (0.02mm). These variations are within standard manufacturing tolerances and do not affect PCB layout or mating compatibility.

Q: What is the current rating and voltage rating for these connectors?

A: The 146742-1 current and voltage ratings are not specified in the available technical data. The Molex 0901522110 is rated for 3A at 350V. For applications requiring specific electrical performance parameters, contact the connector manufacturers directly or consult detailed product datasheets.
