QSH-040-01-L-D-DP-A-TR Equivalent & Substitute Parts

Part Overview

The QSH-040-01-L-D-DP-A-TR is an 80-position differential pair array connector manufactured by Samtec Inc. as part of the Q Strip® QSH series. This surface mount female connector features gold-plated contacts and is designed for high-density interconnect applications requiring differential signaling. The part is currently active in production with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Substitute parts are identified when packaging or inventory requirements necessitate alternative sourcing while maintaining identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

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

• Connector type and gender (Differential Pair Array, Female)
• Position count and row configuration (80 positions, 2 rows)
• Contact pitch (0.020" / 0.50mm)
• Mounting technology (Surface Mount)
• Contact material and finish (Gold, 10.0µin thickness)
• Mechanical dimensions (Height above board, stacking heights)
• Electrical and environmental compliance (ROHS3, MSL 1)

The only allowable variation is packaging format. The primary part is supplied in Tape & Reel (TR) format, while substitute parts may be supplied in alternative packaging such as Tray, provided all other specifications remain identical. This distinction affects handling, storage, and procurement logistics but does not alter electrical or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both the QSH-040-01-L-D-DP-A-TR and QSH-040-01-L-D-DP-A are active production parts from Samtec Inc. with identical electrical, mechanical, and compliance specifications. Selection between these parts is determined by packaging and inventory requirements rather than technical performance.

The QSH-040-01-L-D-DP-A-TR in Tape & Reel format is suitable for automated assembly processes and high-volume production runs. The QSH-040-01-L-D-DP-A in Tray packaging is appropriate for lower-volume applications, manual assembly, or when tape-and-reel handling equipment is unavailable. Both parts meet ROHS3 compliance and carry MSL 1 rating, indicating no moisture sensitivity restrictions during storage or handling.

Frequently Asked Questions (FAQ)

Q: Can QSH-040-01-L-D-DP-A (Tray) be used as a direct replacement for QSH-040-01-L-D-DP-A-TR (Tape & Reel)?

A: Yes. Both parts are electrically and mechanically identical. The difference is packaging format only. Tray-packaged parts are functionally equivalent and will perform identically in the application. Packaging selection depends on assembly process requirements and handling infrastructure.

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 two packaging formats?

A: No compatibility concerns exist. The connector itself is identical. Switching between formats affects only procurement, storage, and assembly handling procedures. PCB footprint, mating interface, and electrical performance are unaffected.

Q: What are the mated stacking height options for this connector?

A: This connector supports seven mated stacking height configurations: 5mm, 8mm, 11mm, 14mm, 16mm, 19mm, and 25mm. Selection depends on the mating connector and application requirements.

Q: Is this connector suitable for high-speed differential signaling applications?

A: This connector is designed as a differential pair array with 80 positions in a 2-row configuration. Specific signal integrity performance depends on application-level design and testing. Consult Samtec technical documentation for detailed electrical characteristics.

Q: What is the contact pitch, and why is it important?

A: The contact pitch is 0.020" (0.50mm). This specification determines PCB footprint, connector density, and compatibility with mating connectors. Any substitute must maintain identical pitch.
