Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the QSE-042-01-L-D-DP-A-TR is determined by strict equivalence across 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)
• Contact finish and thickness (Gold, 10.0µin)
• Mounting technology (Surface Mount)
• Mechanical features (Board Guide, Ground Bus)
• Stacking height compatibility (5mm through 25mm)
• 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 the QSE-042-01-L-D-DP-A-TR and QSE-042-01-L-D-DP-A are Active status products from Samtec Inc. with identical electrical and mechanical specifications. Selection between these parts is determined by packaging and procurement requirements:

• QSE-042-01-L-D-DP-A-TR (Tape & Reel): Suitable for automated assembly processes and high-volume production runs.
• QSE-042-01-L-D-DP-A (Tray): Suitable for manual assembly, lower-volume applications, or when tape & reel packaging is not required.

Both parts maintain ROHS3 compliance and MSL 1 rating. No functional or performance differences exist between these variants.

Frequently Asked Questions (FAQ)

Q: Can QSE-042-01-L-D-DP-A be used as a direct replacement for QSE-042-01-L-D-DP-A-TR?

A: Yes. The parts are electrically and mechanically identical. The only difference is packaging format (Tray versus Tape & Reel). Substitution is valid for any application where the connector specifications are met.

Q: Does packaging format affect connector performance or reliability?

A: No. Packaging format does not affect electrical performance, mechanical fit, or reliability. Both formats contain the same connector component with identical specifications.

Q: Are there any compliance or certification differences between these parts?

A: No. Both parts carry identical ROHS3 compliance and MSL 1 rating. All regulatory and environmental certifications are equivalent.

Q: Which packaging format should be selected for automated assembly?

A: Tape & Reel (TR) packaging is designed for automated pick-and-place assembly processes. Tray packaging is suitable for manual assembly or lower-volume applications.

Q: What are the mated stacking height options for this connector?

A: The QSE-042-01-L-D-DP-A-TR and QSE-042-01-L-D-DP-A support mated stacking heights of 5mm, 8mm, 11mm, 14mm, 16mm, 19mm, and 25mm, allowing flexibility in system design and board-to-board spacing requirements.
