Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the QFS-016-04.25-L-D-DP-A-TR is determined by strict equivalence across the following critical parameters:

• Connector type and gender (Differential Pair Array, Female)
• Number of positions (32)
• Pitch specification (0.025" / 0.64mm)
• Number of rows (2)
• Mounting technology (Surface Mount)
• Contact finish and thickness (Gold, 10.0µin)
• Height above board (0.278")
• Mated stacking heights (10mm, 11mm, 14mm)
• Electrical features (Board Guide, Ground Bus)
• Compliance certifications (ROHS3)

The identified substitute differs only in packaging format (Tape & Reel versus Tray), which does not affect electrical or mechanical compatibility. All other specifications remain identical.

Parameter Comparison

Engineering Selection Recommendations

Both the QFS-016-04.25-L-D-DP-A-TR and QFS-016-04.25-L-D-DP-A are active products from Samtec Inc. with identical electrical and mechanical specifications. Selection between these parts is determined by packaging and supply chain requirements:

The QFS-016-04.25-L-D-DP-A-TR is supplied in Tape & Reel format, suitable for automated assembly processes and high-volume production runs. The QFS-016-04.25-L-D-DP-A is supplied in Tray packaging, appropriate for lower-volume applications or manual assembly workflows.

Both parts maintain ROHS3 compliance and MSL 1 rating, ensuring compatibility with standard manufacturing and storage protocols. The choice between these substitutes depends solely on production methodology and inventory management practices, not on functional or performance characteristics.

Frequently Asked Questions (FAQ)

Q: Can QFS-016-04.25-L-D-DP-A be used as a direct replacement for QFS-016-04.25-L-D-DP-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 main part is specified.

Q: What is the significance of the "-TR" suffix in the part number?

A: The "-TR" suffix designates Tape & Reel packaging. Removal of this suffix indicates Tray packaging. All other specifications remain unchanged.

Q: Are there any compatibility concerns when switching between these packaging formats?

A: No. Packaging format does not affect connector performance, pin configuration, electrical characteristics, or mechanical fit. The components themselves are identical.

Q: Do both parts meet the same compliance standards?

A: Yes. Both QFS-016-04.25-L-D-DP-A-TR and QFS-016-04.25-L-D-DP-A are ROHS3 compliant with MSL 1 rating. Compliance certifications are equivalent.

Q: Which packaging format is preferred for automated assembly?

A: Tape & Reel (QFS-016-04.25-L-D-DP-A-TR) is the standard format for automated pick-and-place assembly. Tray packaging (QFS-016-04.25-L-D-DP-A) is typically used for manual assembly or lower-volume production.
