Substitute Part Grouping Explanation

Substitution eligibility for the QFS-052-04.25-H-D-A-P is determined by strict equivalence across all electrical and mechanical parameters. The identified substitute maintains identical specifications for connector type, position count, pitch, row configuration, mounting method, contact material and thickness, board height, stacking heights, and integrated features. The only permitted variation is packaging format, which does not affect component functionality or PCB integration. Both the tray-packaged main part and tape & reel-packaged substitute are qualified for direct substitution based on:

• Identical 104-position, 2-row configuration at 0.025" pitch
• Matching gold contact finish at 30.0µin thickness
• Equivalent surface mount integration with identical board height and stacking compatibility
• Identical compliance certifications (RoHS3, MSL 1)
• Same base product number (QFS-052) and series designation (Power Q2™ QFS)

Parameter Comparison

Engineering Selection Recommendations

Both QFS-052-04.25-H-D-A-P and QFS-052-04.25-H-D-A-P-TR are Active status components with full RoHS3 compliance and REACH unaffected designation. Selection between these parts is driven by manufacturing process requirements rather than electrical or mechanical performance differences. The tray-packaged variant is suitable for manual assembly, rework operations, and lower-volume production runs. The tape & reel variant is optimized for automated pick-and-place assembly, high-volume manufacturing, and continuous production workflows. Both parts carry identical compliance certifications and environmental ratings, ensuring equivalent reliability and regulatory acceptance in end-use applications.

Frequently Asked Questions (FAQ)

Q: Can QFS-052-04.25-H-D-A-P-TR be used as a direct replacement for QFS-052-04.25-H-D-A-P?

A: Yes. Both parts are electrically and mechanically identical. The only difference is packaging format (tape & reel versus tray). PCB design, assembly parameters, and functional performance remain unchanged.

Q: Does packaging format affect connector performance or reliability?

A: No. Packaging format is a manufacturing and logistics consideration only. Once the component is removed from its packaging and assembled to the PCB, both variants perform identically.

Q: What is the primary reason to select tape & reel packaging?

A: Tape & reel packaging is designed for automated assembly equipment. It enables continuous pick-and-place operations, reduces manual handling, and is standard for high-volume production environments.

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

A: No. Both parts carry identical RoHS3 compliance, MSL 1 rating, and REACH unaffected status. Regulatory and environmental qualifications are equivalent.

Q: Can these parts be interchanged mid-production?

A: Yes, provided your assembly process can accommodate the packaging format. If your line is configured for tape & reel input, the tray-packaged variant requires manual feeder setup. Conversely, automated lines may require reconfiguration to accept tray packaging.
