Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the QSH-090-01-C-D-A-TR is determined by strict equivalence across the following critical parameters:

• Number of positions: 180
• Pitch: 0.020" (0.50mm)
• Number of rows: 2
• Connector type: Receptacle, Center Strip Contacts
• Mounting type: Surface Mount
• Contact finish: Gold
• Contact finish thickness: 50.0µin (1.27µm)
• Height above board: 0.128" (3.25mm)
• Mated stacking heights: 5mm, 8mm, 11mm, 14mm, 16mm, 19mm, 25mm
• Features: Board Guide, Ground Bus (Plane)
• Series: Q Strip® QSH
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity level: 1 (Unlimited)

The identified substitute part differs only in packaging configuration (Tray versus Tape & Reel), which does not affect electrical or mechanical performance in the application.

Parameter Comparison

Engineering Selection Recommendations

Both the QSH-090-01-C-D-A-TR and QSH-090-01-C-D-A are active production parts from Samtec Inc. with identical electrical and mechanical specifications. Selection between these parts is determined by packaging requirements and supply chain considerations rather than technical performance criteria.

The QSH-090-01-C-D-A-TR in Tape & Reel packaging is suitable for automated assembly processes requiring continuous feed capability. The QSH-090-01-C-D-A in Tray packaging accommodates manual assembly workflows or applications where reel-based handling is not required.

Both parts maintain ROHS3 compliance and MSL 1 rating, ensuring compatibility with standard manufacturing processes and storage conditions without special handling requirements.

Frequently Asked Questions (FAQ)

Q: Can QSH-090-01-C-D-A (Tray) be used as a direct replacement for QSH-090-01-C-D-A-TR (Tape & Reel)?

A: Yes. The parts are electrically and mechanically identical. The difference is packaging only. Tray packaging is suitable for manual pick-and-place or lower-volume assembly. Tape & Reel packaging is optimized for automated high-speed assembly lines.

Q: Are there any differences in contact performance between these two part numbers?

A: No. Both parts feature identical gold plating at 50.0µin (1.27µm) thickness, the same 180-position configuration, 0.020" pitch, and center strip contact design. Electrical performance is equivalent.

Q: What is the significance of the "-TR" suffix in QSH-090-01-C-D-A-TR?

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

Q: Do both parts have the same moisture sensitivity requirements?

A: Yes. Both parts carry MSL 1 (Unlimited) rating, meaning they do not require special moisture control during storage or handling.

Q: Are both parts currently in production?

A: Yes. Both QSH-090-01-C-D-A-TR and QSH-090-01-C-D-A maintain active production status with current inventory availability.
