Key Parameters

Substitute Part Grouping Explanation

Substitution for the QTH-020-02-L-D-DP-A-K is determined by equivalence across all electrical and mechanical parameters. The critical parameters defining substitutability are:

• Connector type and gender (Differential Pair Array, Male)
• Position count (40 positions)
• Pitch specification (0.020" / 0.50mm)
• Row configuration (2 rows)
• Contact finish and thickness (Gold, 10.0µin)
• Mounting method (Surface Mount)
• Physical dimensions (Height above board, mated stacking height)
• Compliance certifications (RoHS3, REACH status)

The identified substitute differs only in packaging format (Cut Tape versus Tray), which does not affect electrical performance, mechanical fit, or functional compatibility. Both parts share identical base product number QTH-020 and maintain equivalent specifications across all performance-critical parameters.

Parameter Comparison

Engineering Selection Recommendations

Both QTH-020-02-L-D-DP-A-K and QTH-020-02-L-D-DP-A-K-TR are active production parts with identical electrical and mechanical specifications. Selection between these parts is determined by assembly process requirements and packaging compatibility with automated pick-and-place equipment.

The Tray packaging (QTH-020-02-L-D-DP-A-K) is suitable for high-volume automated assembly operations using standard tray feeders. The Cut Tape packaging (QTH-020-02-L-D-DP-A-K-TR) accommodates tape-based component feeders and is compatible with sequential pick-and-place systems.

Both parts maintain full RoHS3 compliance and REACH unaffected status, ensuring regulatory compliance across all applications. The unlimited moisture sensitivity level (MSL 1) eliminates bake-out requirements prior to assembly.

Frequently Asked Questions (FAQ)

Q: Can QTH-020-02-L-D-DP-A-K-TR be used as a direct replacement for QTH-020-02-L-D-DP-A-K?

A: Yes. Both parts are electrically and mechanically identical. The only difference is packaging format (Cut Tape versus Tray). Substitution is valid provided the receiving assembly process supports the alternate packaging format.

Q: What determines compatibility between these substitute parts?

A: Compatibility is ensured through identical specifications across connector type, position count, pitch, row configuration, contact finish, mounting method, physical dimensions, and compliance certifications. Packaging format does not affect functional performance or mechanical fit.

Q: Are there any assembly process considerations when switching between packaging formats?

A: Yes. Equipment compatibility must be verified. Tray-fed systems require tray packaging; tape-fed systems require cut tape packaging. Verify your assembly equipment specifications before procurement.

Q: Do both parts require the same handling and storage procedures?

A: Yes. Both parts share identical moisture sensitivity level (MSL 1 - Unlimited), eliminating special storage or bake-out requirements. Standard component handling procedures apply to both packaging formats.

Q: What is the base product number for these parts?

A: Both QTH-020-02-L-D-DP-A-K and QTH-020-02-L-D-DP-A-K-TR share the base product number QTH-020, confirming their fundamental equivalence within the Q Strip® QTH series.
