QTE-020-03-F-D-A-TR Equivalent & Substitute Parts

Part Overview

The QTE-020-03-F-D-A-TR is a 40-position rectangular connector header manufactured by Samtec Inc. as part of the Q Strip® QTE series. This surface mount component features outer shroud contacts with gold plating and is designed for applications requiring dual-row header connectivity with board guide and ground bus plane features. The part maintains Active product status with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Substitute parts are identified based on identical electrical and mechanical specifications with variations limited to packaging configuration.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the QTE-020-03-F-D-A-TR is determined by strict equivalence across the following critical parameters:

• Number of positions: 40
• Pitch: 0.031" (0.80mm)
• Number of rows: 2
• Connector type: Header, Outer Shroud Contacts
• Mounting type: Surface Mount
• Contact finish: Gold with 3.00µin thickness
• Height above board: 0.404" (10.27mm)
• Mated stacking height: 11mm
• Features: Board Guide, Ground Bus (Plane)
• Series: Q Strip® QTE
• RoHS compliance: ROHS3
• Moisture sensitivity: MSL 1

Variations in packaging configuration (Tape & Reel versus Tray) do not affect electrical or mechanical compatibility and are therefore permissible substitution criteria.

Parameter Comparison

Engineering Selection Recommendations

Both the QTE-020-03-F-D-A-TR and QTE-020-03-F-D-A maintain Active product status within the Q Strip® QTE series and satisfy ROHS3 compliance requirements. Selection between these parts is determined by packaging and supply chain requirements rather than electrical or mechanical performance. The Tape & Reel packaging of the QTE-020-03-F-D-A-TR is suitable for automated assembly processes, while the Tray packaging of the QTE-020-03-F-D-A accommodates alternative handling and storage methodologies. Both configurations deliver identical connector performance, contact characteristics, and board integration properties.

Frequently Asked Questions (FAQ)

Q: Can QTE-020-03-F-D-A be used as a direct replacement for QTE-020-03-F-D-A-TR?

A: Yes. Both parts are electrically and mechanically identical. The only difference is packaging format: Tape & Reel versus Tray. This distinction does not affect connector functionality, mating characteristics, or PCB assembly compatibility.

Q: What determines substitution eligibility for this connector header?

A: Substitution is valid only when all of the following parameters match: 40-position count, 0.031" (0.80mm) pitch, 2-row configuration, Header with Outer Shroud Contacts type, Surface Mount mounting, Gold contact finish at 3.00µin thickness, 0.404" (10.27mm) height above board, 11mm mated stacking height, Board Guide and Ground Bus features, Q Strip® QTE series designation, ROHS3 compliance, and MSL 1 rating.

Q: Does packaging format affect PCB assembly or connector performance?

A: No. Tape & Reel and Tray packaging formats serve different supply chain and manufacturing workflows but do not alter electrical performance, mechanical fit, or mating reliability of the connector header.

Q: Are both parts suitable for high-reliability applications?

A: Both QTE-020-03-F-D-A-TR and QTE-020-03-F-D-A maintain Active product status and ROHS3 compliance. Selection should be based on application-specific requirements and supply availability rather than reliability differentiation.
