QSH-090-01-F-D-A-TR Equivalent & Substitute Parts

Part Overview

The QSH-090-01-F-D-A-TR is a 180-position rectangular connector receptacle manufactured by Samtec Inc. as part of the Q Strip® QSH series. This surface mount connector features center strip contacts with gold plating and is designed for applications requiring high-density interconnection with multiple stacking height options. The part is currently active in production status with full RoHS3 compliance and unlimited moisture sensitivity rating. 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-090-01-F-D-A-TR is determined by strict equivalence across the following critical parameters:

• Manufacturer and series consistency (Samtec Inc., Q Strip® QSH)
• Electrical specifications: 180 positions, 0.020" pitch, 2-row configuration
• Mechanical compatibility: Surface mount, center strip contacts, identical height above board
• Contact properties: Gold finish at 3.00µin thickness
• Compliance certifications: RoHS3 compliance and MSL 1 rating

The identified substitute part QSH-090-01-F-D-A differs only in packaging format (Tray versus Tape & Reel), which does not affect electrical or mechanical performance. All other specifications remain identical.

Parameter Comparison

Engineering Selection Recommendations

Both the QSH-090-01-F-D-A-TR and QSH-090-01-F-D-A are active production parts with identical electrical and mechanical specifications. Selection between these parts is determined by packaging and inventory requirements rather than technical performance criteria. The main part is supplied in Tape & Reel format, while the substitute is supplied in Tray format. Both parts maintain full RoHS3 compliance and unlimited moisture sensitivity rating, ensuring equivalent performance in all application contexts.

Frequently Asked Questions (FAQ)

Q: Can QSH-090-01-F-D-A be used as a direct replacement for QSH-090-01-F-D-A-TR?

A: Yes. Both parts are electrically and mechanically identical. The only difference is packaging format: Tape & Reel versus Tray. This distinction does not affect connector performance, pin configuration, or board-level compatibility.

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

A: The "-TR" suffix designates Tape & Reel packaging, which is a continuous reel format commonly used for automated assembly processes. The substitute part without this suffix uses Tray packaging, which is a discrete container format.

Q: Are there any compliance differences between these parts?

A: No. Both parts carry identical RoHS3 compliance certification and MSL 1 (Unlimited) moisture sensitivity rating. They are equivalent for all regulatory and environmental requirements.

Q: What are the mated stacking height options?

A: Both parts support seven mated stacking heights: 5mm, 8mm, 11mm, 14mm, 16mm, 19mm, and 25mm. Selection of stacking height is determined by application requirements and does not affect interchangeability between the two packaging formats.

Q: How does the 0.020" pitch affect connector selection?

A: The 0.020" (0.50mm) pitch is a fixed specification for the Q Strip® QSH series. This pitch determines the spacing between the 180 contact positions across the 2-row configuration and is identical in both the main part and substitute part.
