Substitute Part Grouping Explanation
Substitution between QSH-020-01-C-D-DP-A-K and QSH-020-01-C-D-DP-A-K-TR is determined by electrical and mechanical parameter equivalence. Both parts share identical specifications across all critical parameters: connector type, position count, pitch, row configuration, mounting method, contact material and thickness, board height, stacking height options, and feature set. The sole differentiating factor is packaging format: Tray versus Tape & Reel. This packaging difference does not affect electrical performance, mechanical fit, or functional compatibility in the end application. Both parts maintain identical RoHS3 compliance, MSL rating, and Active product status.

Engineering Selection Recommendations
Both QSH-020-01-C-D-DP-A-K and QSH-020-01-C-D-DP-A-K-TR are suitable for direct substitution in applications requiring 40-position differential pair array connectors with 0.020" pitch. Selection between these parts should be based on assembly process requirements and supply chain logistics. Tray packaging is appropriate for manual assembly or lower-volume production runs. Tape & Reel packaging is optimized for automated pick-and-place assembly processes and high-volume manufacturing. Both parts carry identical compliance certifications: ROHS3, REACH Unaffected, and EAR99 export classification. Both maintain Active product status with unlimited moisture sensitivity rating, ensuring long-term availability and reliability in production environments.
Frequently Asked Questions (FAQ)
Q: Can QSH-020-01-C-D-DP-A-K-TR be used as a direct replacement for QSH-020-01-C-D-DP-A-K?
A: Yes. Both parts are electrically and mechanically identical. The only difference is packaging format. The connector itself, its electrical performance, mechanical fit, and functional characteristics are identical.
Q: What is the difference between Tray and Tape & Reel packaging?
A: Tray packaging is used for manual handling and lower-volume assembly. Tape & Reel packaging is designed for automated pick-and-place equipment and high-volume production. The connector component itself is unchanged.
Q: Are there any compliance or certification differences between these parts?
A: No. Both parts carry identical RoHS3 compliance, REACH Unaffected status, MSL 1 rating, and EAR99 export classification.
Q: Which packaging should I select for my application?
A: Select based on your assembly process. Use Tray for manual or semi-automated assembly. Use Tape & Reel for fully automated pick-and-place assembly lines.
Q: Are both parts currently available?
A: Yes. Both parts maintain Active product status. QSH-020-01-C-D-DP-A-K (Tray) has 1022 units in stock. QSH-020-01-C-D-DP-A-K-TR (Tape & Reel) has 1235 units in stock.
Q: Do the mated stacking heights differ between packaging options?
A: No. Both parts support identical mated stacking heights: 5mm, 8mm, 11mm, 14mm, 16mm, 19mm, and 25mm.
