QTH-040-01-F-D-DP-A-TR Equivalent & Substitute Parts

Part Overview

The QTH-040-01-F-D-DP-A-TR is an 80-position differential pair array connector manufactured by Samtec Inc. as part of the Q Strip® QTH series. This surface mount male connector features gold-plated contacts and is designed for high-density interconnect applications requiring differential signaling. The part maintains Active product status with full RoHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Substitute parts are identified based on identical electrical and mechanical specifications with variations limited to packaging configuration.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the QTH-040-01-F-D-DP-A-TR is determined by strict equivalence across the following critical parameters:

• Connector type and gender (Differential Pair Array, Male)
• Position count (80 positions)
• Pitch specification (0.020" / 0.50mm)
• Row configuration (2 rows)
• Mounting technology (Surface Mount)
• Contact material and finish (Gold, 3.00µin thickness)
• Mechanical dimensions (5mm mated stacking height, 0.160" height above board)
• Electrical and environmental compliance (RoHS3, MSL 1)

The identified substitute part differs only in packaging configuration (Tape & Reel versus Tray), which does not affect electrical or mechanical compatibility. Both parts share identical base product number QTH-040 and maintain equivalent functional performance in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

Both the QTH-040-01-F-D-DP-A-TR and QTH-040-01-F-D-DP-A maintain Active product status with full RoHS3 compliance and MSL 1 rating. Selection between these parts is determined by procurement and assembly requirements rather than functional compatibility. The Tape & Reel packaging (TR suffix) is optimized for automated pick-and-place assembly operations, while Tray packaging accommodates manual handling and lower-volume applications. Both configurations deliver identical electrical performance and mechanical fit within the same PCB footprint. Inventory availability and supply chain logistics should guide final part selection.

Frequently Asked Questions (FAQ)

Q: Can QTH-040-01-F-D-DP-A be used as a direct replacement for QTH-040-01-F-D-DP-A-TR?

A: Yes. Both parts are electrically and mechanically identical. The only difference is packaging format (Tray versus Tape & Reel). PCB footprint, mating interface, and electrical performance are equivalent.

Q: Does packaging format affect connector performance or reliability?

A: No. Packaging format impacts only handling, storage, and assembly methodology. Electrical characteristics, contact resistance, and mechanical durability remain unchanged between packaging options.

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

A: No. Both parts carry identical RoHS3 compliance, MSL 1 rating, and Active product status. Environmental and regulatory certifications are equivalent.

Q: What is the significance of the 0.020" pitch specification?

A: The 0.020" (0.50mm) pitch defines the center-to-center spacing between adjacent contact positions. This specification is critical for PCB layout and mating connector design. Both substitute parts maintain this identical pitch.

Q: How do the differential pair array and ground bus features affect substitution?

A: These features are integral to the connector design and are present in both the main part and substitute. They do not create substitution restrictions; rather, they define the functional category of compatible applications.
