Key Parameters

Substitute Part Grouping Explanation

Substitution for the QFS-052-01-SL-D-RA-TR is determined by equivalence in the following critical parameters:

• Connector type and position count (104-position receptacle)
• Electrical pitch and row configuration (0.025" pitch, 2 rows)
• Mounting method and orientation (surface mount, right angle)
• Contact material and finish specifications (gold, 10.0µin thickness)
• Functional features (ground bus plane)
• Compliance certifications (ROHS3, MSL 1)

The substitute part QFS-052-01-SL-D-RA differs only in packaging format (Tray versus Tape & Reel). All electrical, mechanical, and performance characteristics remain identical. This substitution is valid for applications where packaging format does not impose supply chain or assembly constraints.

Parameter Comparison

Engineering Selection Recommendations

Both the QFS-052-01-SL-D-RA-TR and QFS-052-01-SL-D-RA maintain Active product status from Samtec Inc. and carry identical ROHS3 compliance and MSL 1 certifications. Selection between these parts should be based on supply chain requirements and assembly process compatibility. The Tape & Reel format (TR) is optimized for automated pick-and-place assembly, while the Tray format supports manual handling and lower-volume applications. Both formats deliver equivalent electrical and mechanical performance for the 104-position Power Q2™ QFS rectangular connector receptacle.

Frequently Asked Questions (FAQ)

Q: Are QFS-052-01-SL-D-RA-TR and QFS-052-01-SL-D-RA electrically identical?

A: Yes. Both parts are 104-position receptacles with identical pitch (0.025"), row configuration (2 rows), contact finish (gold, 10.0µin), and ground bus plane features. Electrical performance is equivalent.

Q: What is the difference between Tape & Reel and Tray packaging?

A: Tape & Reel (TR) packaging is designed for automated assembly equipment and high-volume production. Tray packaging is used for manual handling and lower-volume applications. The connector specifications remain unchanged.

Q: Can I use QFS-052-01-SL-D-RA in place of QFS-052-01-SL-D-RA-TR?

A: Yes, provided your assembly process can accommodate Tray packaging. The connector itself is functionally identical. Verify that your pick-and-place equipment or manual assembly workflow supports the Tray format.

Q: Are both parts ROHS3 compliant?

A: Yes. Both QFS-052-01-SL-D-RA-TR and QFS-052-01-SL-D-RA are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity.

Q: What is the base product number for these connectors?

A: The base product number is QFS-052. Both substitute parts are variants of this base product with identical core specifications.
