QSH-020-01-H-D-DP-A-TR Equivalent & Substitute Parts

Part Overview

The QSH-020-01-H-D-DP-A-TR is a 40-position differential pair array connector manufactured by Samtec Inc. in 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 distribution format differs while maintaining identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the QSH-020-01-H-D-DP-A-TR is determined by equivalence in the following critical parameters:

• Connector type and gender (Differential Pair Array, Female)
• Number of positions (40)
• Pitch specification (0.020" / 0.50mm)
• Row configuration (2 rows)
• Contact finish and thickness (Gold, 30.0µin)
• Mounting technology (Surface Mount)
• Height above board (0.128")
• Mechanical features (Board Guide, Ground Bus)
• Compliance certifications (ROHS3, MSL 1)

The identified substitute differs only in packaging format (Tape & Reel versus Tray), which does not affect electrical or mechanical performance. All other specifications remain identical.

Parameter Comparison

Engineering Selection Recommendations

Both the QSH-020-01-H-D-DP-A-TR and QSH-020-01-H-D-DP-A are active production parts with identical electrical and mechanical specifications. Selection between these parts is determined by packaging and supply chain requirements rather than technical performance.

The QSH-020-01-H-D-DP-A-TR in Tape & Reel packaging is optimized for automated assembly processes. The QSH-020-01-H-D-DP-A in Tray packaging is suitable for manual assembly or lower-volume applications. Both parts maintain ROHS3 compliance and unlimited moisture sensitivity rating, ensuring compatibility with standard manufacturing and storage protocols.

Frequently Asked Questions (FAQ)

Q: Can QSH-020-01-H-D-DP-A be used as a direct replacement for QSH-020-01-H-D-DP-A-TR?

A: Yes. Both parts are electrically and mechanically identical. The only difference is packaging format (Tray versus Tape & Reel). Selection depends on assembly equipment and process requirements.

Q: Does packaging format affect connector performance or reliability?

A: No. Packaging format does not affect electrical performance, mechanical fit, or reliability. Both formats contain the same connector with identical specifications.

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

A: No. Both parts carry identical ROHS3 compliance and MSL 1 (Unlimited) ratings.

Q: Which packaging format should be selected for high-volume production?

A: Tape & Reel (QSH-020-01-H-D-DP-A-TR) is standard for automated pick-and-place assembly. Tray packaging (QSH-020-01-H-D-DP-A) is used for manual assembly or lower-volume runs.

Q: Are the mated stacking heights identical between substitute parts?

A: Yes. Both parts support the same mated stacking heights: 5mm, 8mm, 11mm, 14mm, 16mm, 19mm, and 25mm.
