Substitute Part Grouping Explanation

Substitution eligibility for the QTH-040-01-L-D-DP-A-TR is determined by equivalence in the following critical parameters:

  • Connector type and gender (Differential Pair Array, Male)
  • Position count (80 positions)
  • Pitch specification (0.020" / 0.50mm)
  • Row configuration (2 rows)
  • Surface mount mounting type
  • Contact finish material and thickness (Gold, 10.0µin)
  • Mechanical dimensions (mated stacking height, height above board)
  • Presence of board guide and ground bus features
  • Base product number (QTH-040)
  • Compliance certifications (ROHS3, MSL 1)

The identified substitute part QTH-040-01-L-D-DP-A differs only in packaging format (Tray versus Tape & Reel). All electrical and mechanical specifications remain identical.

Engineering Selection Recommendations

Both the QTH-040-01-L-D-DP-A-TR and QTH-040-01-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-040-01-L-D-DP-A-TR (Tape & Reel packaging) is suitable for high-volume automated assembly operations where reel-fed component placement is standard. The QTH-040-01-L-D-DP-A (Tray packaging) accommodates manual assembly processes or lower-volume production runs.

Both parts maintain ROHS3 compliance and MSL 1 rating, ensuring compatibility with standard PCB assembly processes and storage conditions.

Frequently Asked Questions (FAQ)

Q: Are QTH-040-01-L-D-DP-A-TR and QTH-040-01-L-D-DP-A electrically and mechanically identical?

A: Yes. Both parts are functionally equivalent. They share identical connector type, position count, pitch, mounting type, contact finish, and mechanical dimensions. The only difference is packaging format.

Q: What is the difference between Tape & Reel and Tray packaging?

A: Tape & Reel (TR) packaging is used for automated pick-and-place assembly systems where components are fed from continuous reels. Tray packaging is used for manual assembly or lower-volume production where components are stored in compartmented trays.

Q: Can I substitute QTH-040-01-L-D-DP-A for QTH-040-01-L-D-DP-A-TR in my design?

A: Yes, from a functional and mechanical standpoint. The substitute part maintains all electrical specifications and physical dimensions. Substitution feasibility depends on your assembly process capability to handle tray-packaged components.

Q: Are both parts RoHS compliant?

A: Yes. Both QTH-040-01-L-D-DP-A-TR and QTH-040-01-L-D-DP-A are ROHS3 compliant.

Q: What is the moisture sensitivity level for these connectors?

A: Both parts have MSL 1 rating, indicating unlimited shelf life under standard storage conditions without baking requirements.

Q: Do these connectors include ground bus features?

A: Yes. Both parts feature a ground bus (plane) and board guide for signal integrity and mechanical alignment.
