QFS-052-04.25-L-D-A-P Equivalent & Substitute Parts

Part Overview

The QFS-052-04.25-L-D-A-P is a 104-position rectangular connector receptacle manufactured by Samtec Inc. as part of the Power Q2™ QFS series. This surface mount connector features center strip contacts with gold plating and is designed for high-density interconnect applications requiring reliable mating cycles and board-level integration.

The part is currently in active production status with full RoHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Substitute parts may be required due to packaging availability, supply chain considerations, or specific procurement requirements while maintaining identical electrical and mechanical performance.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the QFS-052-04.25-L-D-A-P is determined by strict equivalence across the following critical parameters:

• Connector type and contact configuration (Receptacle, Center Strip Contacts)
• Position count and pitch (104 positions at 0.025")
• Row configuration (2 rows)
• Mounting technology (Surface Mount)
• Contact material and finish specifications (Gold, 10.0µin thickness)
• Physical dimensions (Height Above Board: 0.278", Mated Stacking Heights: 10mm, 11mm, 14mm)
• Compliance certifications (RoHS3, MSL 1)

The primary distinction between the main part and its substitute relates to packaging format only. Both parts share identical electrical and mechanical characteristics, differing only in supply packaging configuration.

Parameter Comparison

Engineering Selection Recommendations

Both QFS-052-04.25-L-D-A-P and QFS-052-04.25-L-D-A-P-TR are functionally equivalent and maintain identical electrical and mechanical performance. Selection between these parts should be based on procurement and assembly process requirements:

The tray-packaged variant (QFS-052-04.25-L-D-A-P) is suitable for manual handling, lower-volume production runs, or applications where individual component access is required during assembly.

The tape and reel variant (QFS-052-04.25-L-D-A-P-TR) is optimized for automated pick-and-place assembly processes and high-volume manufacturing environments. This packaging format provides improved handling efficiency and reduced material waste in automated production workflows.

Both parts carry active product status with full RoHS3 compliance and unlimited moisture sensitivity rating, ensuring long-term availability and regulatory compliance for industrial applications.

Frequently Asked Questions (FAQ)

Q: Are QFS-052-04.25-L-D-A-P and QFS-052-04.25-L-D-A-P-TR electrically identical?

A: Yes. Both parts are electrically and mechanically identical. They differ only in packaging format (Tray versus Tape & Reel). All electrical specifications, contact configurations, and performance characteristics are equivalent.

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

A: The only difference is packaging. QFS-052-04.25-L-D-A-P ships in trays, while QFS-052-04.25-L-D-A-P-TR ships in tape and reel format. This distinction affects supply chain logistics and assembly automation compatibility, not component performance.

Q: Can I use the tape and reel version in manual assembly processes?

A: Yes. While tape and reel packaging is optimized for automated pick-and-place systems, the connector itself functions identically in manual assembly applications. Packaging format does not affect the component's electrical or mechanical performance.

Q: Are both parts RoHS3 compliant?

A: Yes. Both QFS-052-04.25-L-D-A-P and QFS-052-04.25-L-D-A-P-TR are ROHS3 compliant with unlimited moisture sensitivity rating (MSL 1).

Q: Which packaging format should I specify for high-volume production?

A: For high-volume automated assembly, the tape and reel variant (QFS-052-04.25-L-D-A-P-TR) is recommended. For lower-volume or manual assembly processes, the tray-packaged variant (QFS-052-04.25-L-D-A-P) may be more appropriate.
