Key Parameters

Substitute Part Grouping Explanation

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

• Connector type and gender (Differential Pair Array, Male)
• Number of positions (40)
• Pitch specification (0.020" / 0.50mm)
• Row configuration (2 rows)
• Mounting technology (Surface Mount)
• Contact finish and thickness (Gold, 10.0µin)
• Mechanical dimensions (5mm stacking height, 0.160" height above board)
• Electrical and environmental compliance (ROHS3, MSL 1)

The identified substitute part QTH-020-01-L-D-DP-A differs only in packaging format (Tray versus Tape & Reel). All electrical, mechanical, and performance characteristics remain identical. This packaging variation does not affect connector functionality, compatibility, or performance in end applications.

Parameter Comparison

Engineering Selection Recommendations

Both the QTH-020-01-L-D-DP-A-TR and QTH-020-01-L-D-DP-A are active production parts from Samtec Inc. with identical electrical and mechanical specifications. Selection between these parts is determined by packaging and supply chain requirements rather than functional performance.

The QTH-020-01-L-D-DP-A-TR in Tape & Reel packaging is suitable for high-volume automated assembly operations. The QTH-020-01-L-D-DP-A in Tray packaging accommodates manual assembly processes or lower-volume production runs. Both parts maintain ROHS3 compliance and unlimited moisture sensitivity rating, ensuring equivalent environmental performance and regulatory status.

Frequently Asked Questions (FAQ)

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

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

Q: Does packaging format affect connector performance or compatibility?

A: No. Packaging format (Tape & Reel versus Tray) is a supply and assembly consideration only. It does not affect electrical performance, mechanical fit, or mating characteristics.

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

A: No. Both parts carry identical ROHS3 compliance, MSL 1 rating, REACH status, and ECCN classification.

Q: What determines if a part can substitute for the QTH-020-01-L-D-DP-A-TR?

A: Substitution requires exact equivalence in connector type, position count, pitch, row configuration, mounting method, contact finish, mechanical dimensions, and compliance certifications. Packaging format is the only allowable variation.

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

A: The QTH-020-01-L-D-DP-A-TR in Tape & Reel packaging is optimized for automated pick-and-place assembly. The QTH-020-01-L-D-DP-A in Tray packaging is suitable for manual or lower-volume assembly processes.
