The substitute part QSH-040-01-F-D-DP-A differs only in packaging format (Tray versus Tape & Reel). All electrical and mechanical specifications remain identical.

Parameter Comparison

Engineering Selection Recommendations

Both the QSH-040-01-F-D-DP-A-TR and QSH-040-01-F-D-DP-A are Active status products from Samtec Inc. and maintain full ROHS3 compliance. The parts are electrically and mechanically identical. Selection between them is determined by packaging requirements and supply chain considerations. The Tape & Reel format (QSH-040-01-F-D-DP-A-TR) is suitable for automated assembly processes. The Tray format (QSH-040-01-F-D-DP-A) accommodates manual handling and alternative assembly workflows. Both parts carry MSL 1 rating, indicating no moisture sensitivity restrictions during storage and handling.

Frequently Asked Questions (FAQ)

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

A: Yes. The parts are electrically and mechanically identical. The only difference is packaging format: Tape & Reel versus Tray. Substitution is valid provided assembly equipment and handling procedures accommodate the alternate packaging.

Q: What is the significance of the "-TR" suffix in QSH-040-01-F-D-DP-A-TR?

A: The "-TR" suffix designates Tape & Reel packaging, which is standard for automated pick-and-place assembly. The part without this suffix uses Tray packaging.

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

A: No. Both parts carry identical RoHS3 compliance and MSL 1 ratings. Regulatory and environmental certifications are equivalent.

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

A: The connector supports seven mated stacking heights: 5mm, 8mm, 11mm, 14mm, 16mm, 19mm, and 25mm. Selection depends on application-specific spacing requirements.

Q: Is this connector suitable for differential pair signaling applications?

A: Yes. The connector is specifically designed as a Differential Pair Array with 80 positions organized in 2 rows, supporting high-speed differential signaling with integrated ground bus and board guide features.
