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

Part Overview

The QSH-020-01-F-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 inventory requirements necessitate alternative sourcing while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

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

• Connector type: Differential pair array, female configuration
• Electrical specifications: 40-position, 0.020" (0.50mm) pitch, 2-row arrangement
• Contact system: Gold plating at 3.00µin thickness
• Mechanical interface: Surface mount with identical board height (0.128" / 3.25mm) and mated stacking height options
• Functional features: Board guide and ground bus plane
• Compliance: ROHS3 compliance and MSL 1 rating

The identified substitute part differs only in packaging format (tape & reel versus tray), which does not affect electrical or mechanical performance. All other specifications remain identical, ensuring direct functional interchangeability.

Parameter Comparison

Engineering Selection Recommendations

Both the QSH-020-01-F-D-DP-A-TR and QSH-020-01-F-D-DP-A are active production parts with identical ROHS3 compliance and MSL 1 ratings. Selection between these parts is based on packaging and inventory requirements rather than electrical or mechanical performance differences.

The QSH-020-01-F-D-DP-A-TR in tape & reel packaging is suitable for automated assembly processes requiring continuous reel feeding. The QSH-020-01-F-D-DP-A in tray packaging accommodates manual assembly workflows or applications where reel-based handling is not required. Both parts maintain full functional equivalence for differential pair array applications within the specified mated stacking height range.

Frequently Asked Questions (FAQ)

Q: Are QSH-020-01-F-D-DP-A-TR and QSH-020-01-F-D-DP-A electrically identical?

A: Yes. Both parts are identical in electrical specifications, including connector type, position count, pitch, contact finish, and gold plating thickness. They differ only in packaging format.

Q: Can I substitute QSH-020-01-F-D-DP-A for QSH-020-01-F-D-DP-A-TR in production?

A: Yes, provided your assembly process accommodates tray packaging instead of tape & reel. All mechanical and electrical parameters are equivalent.

Q: Do both parts support the same mated stacking heights?

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

Q: Are there compliance differences between the two parts?

A: No. Both parts carry ROHS3 compliance and MSL 1 (unlimited moisture sensitivity) ratings.

Q: What is the board height for both connectors?

A: Both connectors have a height above board of 0.128" (3.25mm).
