Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the QSE-020-01-L-D-A-RT1-TR is determined by strict equivalence across the following critical parameters:

• Connector Type: Receptacle, Center Strip Contacts
• Number of Positions: 40
• Pitch: 0.031" (0.80mm)
• Number of Rows: 2
• Mounting Type: Surface Mount
• Contact Finish: Gold
• Contact Finish Thickness: 10.0µin (0.25µm)
• Height Above Board: 0.128" (3.25mm)
• Mated Stacking Heights: 5mm, 8mm, 11mm, 14mm, 16mm, 19mm, 25mm
• Features: Board Guide, Ground Bus (Plane), Mounting Flange
• Base Product Number: QSE-020
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

The only allowable variation between the main part and its substitutes is the packaging format (Tape & Reel versus Tray). All electrical, mechanical, and environmental specifications must remain identical.

Parameter Comparison

Engineering Selection Recommendations

Both the QSE-020-01-L-D-A-RT1-TR and QSE-020-01-L-D-A-RT1 are Active products with identical electrical and mechanical specifications. Selection between these parts should be based on packaging requirements and procurement workflow:

The QSE-020-01-L-D-A-RT1-TR (Tape & Reel packaging) is suitable for high-volume automated assembly operations where reel-fed component handling is standard.

The QSE-020-01-L-D-A-RT1 (Tray packaging) is suitable for lower-volume applications, manual assembly processes, or procurement scenarios where tray packaging is preferred.

Both parts maintain ROHS3 compliance and MSL 1 rating, ensuring compatibility with standard manufacturing and storage protocols. No additional environmental or compliance considerations differentiate these parts.

Frequently Asked Questions (FAQ)

Q: Can QSE-020-01-L-D-A-RT1 be used as a direct replacement for QSE-020-01-L-D-A-RT1-TR?

A: Yes. Both parts are electrically and mechanically identical. The only difference is packaging format (Tray versus Tape & Reel). Direct substitution is valid from an engineering standpoint, provided your assembly process accommodates the tray packaging format.

Q: What does the "-TR" suffix indicate in the part number?

A: The "-TR" suffix designates Tape & Reel packaging. Removal of this suffix indicates Tray packaging. All other specifications remain unchanged.

Q: Are there any compatibility issues when switching between packaging formats?

A: No. The connector itself is identical. Compatibility concerns are limited to assembly equipment and handling procedures. Verify that your pick-and-place equipment or manual assembly process can accommodate the alternate packaging format.

Q: Do both parts meet the same compliance standards?

A: Yes. Both QSE-020-01-L-D-A-RT1-TR and QSE-020-01-L-D-A-RT1 are ROHS3 compliant with MSL 1 rating. No compliance differentiation exists between these parts.

Q: What are the mated stacking height options?

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