QSH-040-01-C-D-DP-A-TR Equivalent & Substitute Parts

Part Overview

The QSH-040-01-C-D-DP-A-TR is an 80-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 in active production status with RoHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Substitute parts may be required due to packaging availability, inventory constraints, or specific procurement requirements while maintaining identical electrical and mechanical performance.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the QSH-040-01-C-D-DP-A-TR is determined by strict equivalence across the following critical parameters:

Electrical Parameters: 80-position differential pair array configuration, 0.020" (0.50mm) pitch, 2-row layout, gold contact finish at 50.0µin (1.27µm) thickness, and support for mated stacking heights of 5mm through 25mm.

Mechanical Parameters: Surface mount female connector with board guide and ground bus plane features, 0.128" (3.25mm) height above board.

Compliance Parameters: ROHS3 compliance, MSL 1 rating, and active product status.

The only allowable variation is packaging format. The primary part is supplied in Tape & Reel (TR) packaging, while substitute parts may be supplied in alternative packaging such as Tray format, provided all other specifications remain identical.

Parameter Comparison

Engineering Selection Recommendations

Both the QSH-040-01-C-D-DP-A-TR and QSH-040-01-C-D-DP-A are active products from Samtec Inc. with identical electrical and mechanical specifications. Selection between these parts is determined solely by packaging requirements and procurement logistics.

The QSH-040-01-C-D-DP-A-TR in Tape & Reel packaging is suitable for high-volume automated assembly operations where continuous feed from reel-based pick-and-place equipment is required.

The QSH-040-01-C-D-DP-A in Tray packaging is suitable for lower-volume applications, manual assembly processes, or situations where reel-based handling is not compatible with production equipment.

Both parts maintain ROHS3 compliance and unlimited moisture sensitivity rating, ensuring compatibility with standard PCB assembly processes and storage conditions.

Frequently Asked Questions (FAQ)

Q: Are QSH-040-01-C-D-DP-A-TR and QSH-040-01-C-D-DP-A electrically and mechanically identical?

A: Yes. Both parts are identical in all electrical and mechanical parameters, including connector type, position count, pitch, contact finish, and stacking height specifications. The only difference is packaging format.

Q: What is the primary difference between these substitute parts?

A: The QSH-040-01-C-D-DP-A-TR is supplied in Tape & Reel (TR) packaging for automated assembly, while the QSH-040-01-C-D-DP-A is supplied in Tray packaging for manual or lower-volume assembly processes.

Q: Can I use the Tray-packaged part in place of the Tape & Reel part in automated assembly?

A: Tray packaging is not compatible with standard reel-fed pick-and-place equipment. Use of the Tray-packaged part requires manual feeding or alternative feeder systems.

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

A: No. Both parts carry identical ROHS3 compliance, MSL 1 rating, and active product status certifications.

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

A: The connector supports mated stacking heights of 5mm, 8mm, 11mm, 14mm, 16mm, 19mm, and 25mm, allowing flexibility in system design and component density requirements.

Q: Is the contact finish specification the same for both parts?

A: Yes. Both parts feature gold-plated contacts with a thickness of 50.0µin (1.27µm), ensuring consistent electrical performance and corrosion resistance.
