Key Parameters

Substitute Part Grouping Explanation

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

• Connector type and gender (Differential Pair Array, Male)
• Number of positions (40)
• Contact pitch (0.020" / 0.50mm)
• Row configuration (2 rows)
• Mounting technology (Surface Mount)
• Contact material and finish (Gold, 10.0µin thickness)
• Physical dimensions (5mm mated stacking height, 0.160" height above board)
• Regulatory compliance (RoHS3, REACH)
• Moisture sensitivity level (MSL 1)

The identified substitute differs only in packaging configuration, which does not affect electrical or mechanical performance in the application.

Parameter Comparison

Engineering Selection Recommendations

Both QTH-020-01-L-D-DP-A-K and QTH-020-01-L-D-DP-A-K-TR are Active products with identical electrical and mechanical specifications. Selection between these parts is determined by assembly and procurement requirements:

The Tray packaging (QTH-020-01-L-D-DP-A-K) is suitable for manual assembly, prototyping, and lower-volume applications. The Tape & Reel packaging (QTH-020-01-L-D-DP-A-K-TR) is optimized for automated pick-and-place assembly and high-volume production environments.

Both parts maintain full RoHS3 compliance and REACH unaffected status, ensuring regulatory compatibility across applications. MSL 1 rating indicates unlimited shelf life under standard storage conditions.

Frequently Asked Questions (FAQ)

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

A: Yes. Both parts are electrically and mechanically identical. The difference is packaging only. Tape & Reel packaging is suitable for automated assembly, while Tray packaging is used for manual or lower-volume applications.

Q: Does packaging affect connector performance or compatibility?

A: No. Packaging is a supply and assembly consideration only. Once removed from packaging, both parts are functionally identical and perform identically in the application.

Q: Are there any compliance differences between the two packaging options?

A: No. Both parts carry identical RoHS3 compliance, REACH unaffected status, and MSL 1 rating regardless of packaging configuration.

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

A: Tape & Reel (QTH-020-01-L-D-DP-A-K-TR) is the standard packaging for automated pick-and-place assembly in high-volume manufacturing.

Q: What is the significance of the 0.020" pitch specification?

A: The 0.020" (0.50mm) pitch defines the center-to-center spacing between adjacent contact positions. This parameter must match exactly for mechanical and electrical compatibility with mating connectors and PCB layouts.
