QSE-020-01-H-D-A-TR Equivalent & Substitute Parts

Part Overview

The QSE-020-01-H-D-A-TR is a 40-position rectangular connector receptacle manufactured by Samtec Inc. as part of the Q Strip® QSE series. This surface mount component features center strip contacts with gold plating and is designed for applications requiring reliable interconnection with mated stacking height flexibility. The part is currently in active production status with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1).

Identifying equivalent and substitute parts is necessary when the primary packaging format (Tape & Reel) is unavailable or when alternative inventory sources are required while maintaining identical electrical and mechanical performance.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the QSE-020-01-H-D-A-TR is limited to parts that maintain identical electrical and mechanical specifications. The critical parameters determining substitutability are:

• Manufacturer and series consistency (Samtec Inc., Q Strip® QSE)
• Position count and pitch (40 positions, 0.031" / 0.80mm)
• Connector type and contact configuration (Receptacle, Center Strip Contacts)
• Mounting technology (Surface Mount)
• Contact material and finish (Gold, 30.0µin thickness)
• Physical dimensions (Height Above Board: 0.128", Mated Stacking Heights: 5mm–25mm)
• Compliance certifications (ROHS3, MSL 1)

The only allowable variation is packaging format. The QSE-020-01-H-D-A-TR is supplied in Tape & Reel (TR) format. An equivalent part with identical specifications supplied in alternative packaging (Tray) is available as a direct substitute.

Parameter Comparison

Engineering Selection Recommendations

Both the QSE-020-01-H-D-A-TR and QSE-020-01-H-D-A are active production parts with identical electrical and mechanical specifications. Selection between these parts should be based on packaging requirements and inventory availability.

The QSE-020-01-H-D-A-TR in Tape & Reel format is suitable for automated assembly processes requiring continuous reel feeding. The QSE-020-01-H-D-A in Tray packaging is suitable for manual assembly, kit builds, or applications where reel handling infrastructure is not available.

Both parts maintain ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1), ensuring compatibility with standard PCB assembly processes without special handling requirements. No additional testing or qualification is required when substituting between these two packaging formats, provided the connector specifications and mating interface remain unchanged in the application design.

Frequently Asked Questions (FAQ)

Q: Can QSE-020-01-H-D-A (Tray) be used as a direct replacement for QSE-020-01-H-D-A-TR (Tape & Reel)?

A: Yes. Both parts are electrically and mechanically identical. The only difference is packaging format. Substitution is valid for any application where the connector specifications are the design requirement. Assembly process compatibility with the packaging format must be confirmed.

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

A: No. Both parts carry identical ROHS3 compliance, MSL 1 rating, REACH unaffected status, and ECCN/HTSUS classifications.

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

A: The QSE-020-01-H-D-A-TR and QSE-020-01-H-D-A support mated stacking heights of 5mm, 8mm, 11mm, 14mm, 16mm, 19mm, and 25mm. The specific stacking height is determined by the mating plug connector selected for the application.

Q: Does the gold contact finish thickness affect substitutability?

A: No. Both parts have identical contact finish thickness of 30.0µin (0.76µm). This specification is fixed for the QSE series and does not vary between packaging formats.

Q: What is the pitch specification for this connector?

A: The pitch is 0.031" (0.80mm) with 40 positions arranged in 2 rows, resulting in a 20-position-per-row configuration.
