Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the QSE-042-01-F-D-DP-A-TR is determined by equivalence in the following critical parameters:

• Connector type and gender (Differential Pair Array, Female)
• Position count (84 positions)
• Pitch specification (0.031" / 0.80mm)
• Row configuration (2 rows)
• Surface mount mounting type
• Contact finish material and thickness (Gold, 3.00µin)
• Height above board (0.128" / 3.25mm)
• Mated stacking height options
• Integrated features (Board Guide, Ground Bus)
• Compliance certifications (ROHS3, MSL 1)

The identified substitute differs only in packaging format (Tape & Reel versus Tray), which does not affect electrical or mechanical performance. All other specifications remain identical.

Parameter Comparison

Engineering Selection Recommendations

Both QSE-042-01-F-D-DP-A-TR and QSE-042-01-F-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 handling requirements rather than functional performance.

QSE-042-01-F-D-DP-A-TR in Tape & Reel format is suitable for automated assembly processes with high-volume production runs. QSE-042-01-F-D-DP-A in Tray packaging accommodates manual assembly, lower-volume applications, or alternative handling equipment.

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

Frequently Asked Questions (FAQ)

Q: Are QSE-042-01-F-D-DP-A-TR and QSE-042-01-F-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 all mechanical dimensions. The only difference is packaging format.

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

A: Tape & Reel packaging is designed for automated pick-and-place assembly equipment. Tray packaging is used for manual assembly or alternative handling systems. Both formats protect the components during storage and transport.

Q: Can I substitute QSE-042-01-F-D-DP-A for QSE-042-01-F-D-DP-A-TR in my design?

A: Yes, provided your assembly process can accommodate Tray packaging. The connector specifications, performance characteristics, and compliance certifications are identical.

Q: Are both parts RoHS compliant?

A: Yes. Both QSE-042-01-F-D-DP-A-TR and QSE-042-01-F-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 special moisture control requirements.

Q: Do these connectors support multiple mated stacking heights?

A: Yes. Both parts support mated stacking heights of 5mm, 8mm, 11mm, 14mm, 16mm, 19mm, and 25mm, providing flexibility for various application requirements.
