Key Parameters

Substitute Part Grouping Explanation

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

• Connector type and gender (Differential Pair Array, Female)
• Position count (40 positions)
• Pitch specification (0.020" / 0.50mm)
• Row configuration (2 rows)
• Contact material and finish (Gold, 30.0µin thickness)
• Mounting technology (Surface Mount)
• Physical dimensions (Height above board, stacking heights)
• Compliance certifications (ROHS3, MSL 1)

The identified substitute differs only in packaging format, maintaining all electrical and mechanical specifications required for direct functional equivalence.

Parameter Comparison

Engineering Selection Recommendations

Both QSH-020-01-H-D-DP-A-K and QSH-020-01-H-D-DP-A-K-TR are active production parts manufactured by Samtec Inc. with identical electrical and mechanical specifications. Selection between these parts is determined by assembly process requirements and supply chain logistics rather than functional performance.

The tray-packaged QSH-020-01-H-D-DP-A-K is suitable for manual assembly, prototype builds, and lower-volume production runs. The tape and reel packaged QSH-020-01-H-D-DP-A-K-TR is optimized for automated pick-and-place assembly processes and high-volume manufacturing environments.

Both parts maintain ROHS3 compliance and MSL 1 rating, ensuring compatibility with standard PCB assembly processes and long-term storage without moisture bake-out requirements.

Frequently Asked Questions (FAQ)

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

A: Yes. Both parts are functionally equivalent with identical connector specifications, contact configurations, pitch, and electrical performance characteristics.

Q: What is the difference between these two part numbers?

A: The difference is packaging format only. QSH-020-01-H-D-DP-A-K is supplied in trays for manual handling, while QSH-020-01-H-D-DP-A-K-TR is supplied in tape and reel format for automated assembly equipment.

Q: Can I use the tape and reel version in manual assembly?

A: Yes. The tape and reel packaged part can be manually extracted and used in manual assembly processes, though this is not the typical application for this packaging format.

Q: Are there any compliance differences between these parts?

A: No. Both parts carry identical ROHS3 compliance certification and MSL 1 moisture sensitivity rating.

Q: Which part should I specify for high-volume production?

A: The QSH-020-01-H-D-DP-A-K-TR (tape and reel) is the standard choice for high-volume automated assembly due to its compatibility with pick-and-place equipment and tape feeder systems.

Q: Do these parts have the same mated stacking height options?

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