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

Part Overview

The QSH-020-01-C-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 identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the QSH-020-01-C-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
• Mechanical specifications: Surface mount, 0.128" (3.25mm) height above board, board guide and ground bus features
• Contact specifications: Gold finish at 50.0µin (1.27µm) thickness
• Compliance: ROHS3 compliant, MSL 1 rating
• Mated stacking height compatibility: 5mm through 25mm range

The only allowable variation between the main part and substitutes is packaging format (tape & reel versus tray), which does not affect electrical or mechanical performance. All other parameters must remain identical for substitution validity.

Parameter Comparison

Engineering Selection Recommendations

Both the QSH-020-01-C-D-DP-A-TR and QSH-020-01-C-D-DP-A are active production parts from Samtec Inc. with identical electrical and mechanical specifications. Selection between these parts should be based on packaging and inventory requirements:

• QSH-020-01-C-D-DP-A-TR (Tape & Reel): Suitable for high-volume automated assembly operations requiring continuous reel feeding.
• QSH-020-01-C-D-DP-A (Tray): Suitable for lower-volume production, manual assembly, or applications where tray packaging is preferred for handling and storage.

Both parts maintain ROHS3 compliance and MSL 1 rating. No functional or performance differences exist between the two packaging formats.

Frequently Asked Questions (FAQ)

Q: Can QSH-020-01-C-D-DP-A (tray packaging) be used as a direct replacement for QSH-020-01-C-D-DP-A-TR (tape & reel)?

A: Yes. The electrical and mechanical specifications are identical. The only difference is packaging format. Substitution is valid for any application where the connector specifications match the design requirements.

Q: What parameters must remain identical for substitution validity?

A: Connector type, position count (40), pitch (0.020"), row configuration (2), mounting type (surface mount), contact finish (gold at 50.0µin), height above board (0.128"), board guide and ground bus features, and compliance ratings (ROHS3, MSL 1) must all remain unchanged.

Q: Are there any compatibility issues between tape & reel and tray packaging formats?

A: No. Packaging format affects only handling, storage, and assembly line integration. The connectors themselves are functionally identical and fully compatible in any application.

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

A: The QSH-020-01-C-D-DP-A-TR and QSH-020-01-C-D-DP-A support mated stacking heights of 5mm, 8mm, 11mm, 14mm, 16mm, 19mm, and 25mm.

Q: Is this connector RoHS compliant?

A: Yes. Both parts are ROHS3 compliant with MSL 1 (unlimited moisture sensitivity rating).
