QSE-014-01-L-D-DP-A-TR Equivalent & Substitute Parts

Part Overview

The QSE-014-01-L-D-DP-A-TR is a 28-position differential pair array connector manufactured by Samtec Inc. in the Q Strip® QSE series. This female surface mount connector features gold plating and is designed for high-density interconnect applications requiring differential signaling. The part is currently active in production with full RoHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Substitute parts may be required due to packaging availability, inventory constraints, or specific procurement requirements while maintaining identical electrical and mechanical performance.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the QSE-014-01-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 (28 positions)
• Pitch specification (0.031" / 0.80mm)
• Row configuration (2 rows)
• Mounting technology (Surface Mount)
• Contact finish material and thickness (Gold, 10.0µin)
• Height above board (0.128" / 3.25mm)
• Mated stacking height options (5mm through 25mm)
• Electrical features (Board Guide, Ground Bus)
• Compliance certifications (ROHS3, MSL 1)

The primary variable distinguishing substitute parts is packaging format. The QSE-014-01-L-D-DP-A-TR is supplied in Tape & Reel (TR) format, while equivalent parts may be available in alternative packaging such as Tray. All other electrical, mechanical, and environmental specifications remain identical across approved substitutes.

Parameter Comparison

Engineering Selection Recommendations

Both the QSE-014-01-L-D-DP-A-TR and QSE-014-01-L-D-DP-A are active production parts manufactured by Samtec Inc. with identical electrical and mechanical specifications. Selection between these parts is determined solely by packaging requirements and procurement logistics.

The QSE-014-01-L-D-DP-A-TR in Tape & Reel format is optimized for high-volume automated assembly operations. The QSE-014-01-L-D-DP-A in Tray packaging is suitable for lower-volume applications or manual assembly processes.

Both parts maintain full ROHS3 compliance and MSL 1 rating, ensuring compatibility with standard surface mount assembly processes and storage conditions. No functional or performance differences exist between these variants.

Frequently Asked Questions (FAQ)

Q: Can QSE-014-01-L-D-DP-A (Tray) be used as a direct replacement for QSE-014-01-L-D-DP-A-TR (Tape & Reel)?

A: Yes. Both parts are electrically and mechanically identical. The difference is packaging format only. Tray packaging is compatible with manual pick-and-place or lower-volume assembly processes, while Tape & Reel is designed for automated high-speed assembly equipment.

Q: Are there any PCB layout or footprint differences between these parts?

A: No. Both parts share identical mechanical dimensions, pitch, position count, and mounting specifications. PCB footprints are interchangeable.

Q: Do both parts meet the same compliance standards?

A: Yes. Both QSE-014-01-L-D-DP-A-TR and QSE-014-01-L-D-DP-A are ROHS3 compliant with MSL 1 rating and identical ECCN and HTSUS classifications.

Q: What are the mated stacking height options for these connectors?

A: Both parts support mated stacking heights of 5mm, 8mm, 11mm, 14mm, 16mm, 19mm, and 25mm, allowing flexibility in system integration and board-to-board spacing requirements.

Q: Is the gold contact finish specification identical between both parts?

A: Yes. Both parts feature gold contact finish with 10.0µin (0.25µm) thickness, ensuring equivalent electrical performance and reliability.
