• Number of Positions: 104
• Pitch: 0.025" (0.64mm)
• Number of Rows: 2
• Mounting Type: Surface Mount
• Contact Finish: Gold
• Contact Finish Thickness: 30.0µin (0.76µm)
• Height Above Board: 0.212" (5.38mm)
• Mated Stacking Heights: 10mm, 12mm
• Features: Board Guide, Ground Bus (Plane)
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

The identified substitute part differs only in packaging format, which does not affect electrical or mechanical performance in the application.

Parameter Comparison

Engineering Selection Recommendations

Both the QMS-052-05.75-H-D-A-TR and QMS-052-05.75-H-D-A maintain identical electrical and mechanical specifications. Selection between these parts is determined by packaging and supply chain requirements:

The QMS-052-05.75-H-D-A-TR in Tape & Reel packaging is suitable for automated assembly processes requiring continuous component feed. The QMS-052-05.75-H-D-A in Tray packaging is suitable for manual assembly or lower-volume production runs. Both parts are Active status products with ROHS3 compliance and MSL 1 rating, indicating no moisture sensitivity restrictions during storage and handling.

Frequently Asked Questions (FAQ)

Q: Can QMS-052-05.75-H-D-A be used as a direct replacement for QMS-052-05.75-H-D-A-TR?

A: Yes. Both parts are electrically and mechanically identical. The only difference is packaging format (Tray versus Tape & Reel). Substitution is valid for any application where the connector specifications match the design requirements.

Q: Does packaging format affect component performance?

A: No. Packaging format affects only supply chain logistics and assembly process compatibility. Electrical and mechanical performance remain identical between Tape & Reel and Tray packaging options.

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

A: No. Both parts carry identical RoHS3 compliance status and MSL 1 rating. Regulatory and environmental certifications are equivalent.

Q: What is the significance of the base product number QMS-052?

A: The base product number QMS-052 identifies the core connector design within the Power Q2™ QMS series. Variations in the full part number (such as packaging designation) represent different configurations of the same base design.

Q: Can these parts be used interchangeably in PCB assembly?

A: Yes, provided the assembly process is compatible with the packaging format. Tape & Reel packaging is optimized for pick-and-place automation, while Tray packaging is suitable for manual placement or alternative assembly methods. Once soldered to the PCB, both configurations are functionally identical.
