Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the QTH-020-04-L-D-DP-A-TR is determined by equivalence in the following critical parameters: connector type (differential pair array, male), number of positions (40), pitch (0.020"/0.50mm), number of rows (2), mounting type (surface mount), contact finish (gold at 10.0µin thickness), mechanical dimensions (height above board and mated stacking height), and series designation (Q Strip® QTH). The identified substitute part QTH-020-04-L-D-DP-A maintains all electrical and mechanical specifications while differing only in packaging format. This substitution is valid for applications where packaging configuration does not impose constraints on assembly or logistics workflows.

Parameter Comparison

Engineering Selection Recommendations

Both the QTH-020-04-L-D-DP-A-TR and QTH-020-04-L-D-DP-A are active production parts from Samtec Inc. with identical electrical and mechanical specifications. Selection between these parts should be based on packaging requirements and assembly process compatibility. The tape and reel format (TR) is optimized for automated pick-and-place assembly operations, while the tray format accommodates manual assembly workflows or alternative handling systems. Both parts maintain ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1), ensuring regulatory and environmental compatibility across applications. Inventory availability should be evaluated against procurement lead times and production schedules.

Frequently Asked Questions (FAQ)

Q: Are QTH-020-04-L-D-DP-A-TR and QTH-020-04-L-D-DP-A electrically identical?

A: Yes. Both parts are functionally equivalent with identical connector type, position count, pitch, row configuration, contact finish, and mechanical dimensions. Electrical performance and signal integrity characteristics are equivalent.

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

A: The difference is packaging format only. QTH-020-04-L-D-DP-A-TR is supplied in tape and reel format, while QTH-020-04-L-D-DP-A is supplied in tray format. All other specifications remain identical.

Q: Can I substitute the tray-packaged part for the tape and reel part in my assembly process?

A: Substitution is valid only if your assembly process can accommodate tray-format components. Automated pick-and-place systems typically require tape and reel format. Manual assembly or alternative handling systems may accept tray format. Verify compatibility with your specific assembly equipment and workflow.

Q: Do both parts meet the same compliance standards?

A: Yes. Both parts are ROHS3 compliant with MSL 1 (unlimited moisture sensitivity). Both carry EAR99 ECCN classification and identical HTSUS codes.

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

A: For automated assembly, the tape and reel format (QTH-020-04-L-D-DP-A-TR) is standard. Verify current inventory levels and lead times with your supplier, as availability may influence selection timing.
