QTH-020-03-L-D-DP-A-TR Equivalent & Substitute Parts

Part Overview

The QTH-020-03-L-D-DP-A-TR is a 40-position differential pair array connector manufactured by Samtec Inc. as part of the Q Strip® QTH series. This surface mount male connector features gold-plated contacts and is designed for high-density interconnect applications requiring differential signaling. The part is currently in active production 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

Substitute parts for the QTH-020-03-L-D-DP-A-TR are determined by equivalence in the following critical parameters:

• Connector type and gender (Differential Pair Array, Male)
• Position count (40 positions)
• Pitch specification (0.020" / 0.50mm)
• Row configuration (2 rows)
• Contact finish and thickness (Gold, 10.0µin)
• Mounting technology (Surface Mount)
• Physical dimensions (Height above board, mated stacking height)
• Electrical features (Board Guide, Ground Bus)
• Compliance certifications (ROHS3, MSL 1)

The identified substitute part differs only in packaging configuration, transitioning from Tape & Reel (TR) to Tray packaging. This distinction affects handling, storage, and supply chain logistics but does not alter electrical or mechanical performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

Both the QTH-020-03-L-D-DP-A-TR and QTH-020-03-L-D-DP-A maintain identical electrical and mechanical specifications. Selection between these parts is determined by packaging and supply requirements rather than functional performance.

The QTH-020-03-L-D-DP-A-TR in Tape & Reel packaging is suitable for high-volume automated assembly operations where continuous feed from reel-based pick-and-place systems is required. The QTH-020-03-L-D-DP-A in Tray packaging accommodates manual assembly processes or lower-volume production runs where individual component handling is preferred.

Both parts carry active product status, ROHS3 compliance, and MSL 1 rating, confirming suitability for standard manufacturing environments without special moisture control requirements.

Frequently Asked Questions (FAQ)

Q: Can QTH-020-03-L-D-DP-A (Tray) be used as a direct replacement for QTH-020-03-L-D-DP-A-TR (Tape & Reel)?

A: Yes. The electrical and mechanical specifications are identical. The only difference is packaging format. Tray-packaged components can be used in applications originally designed for Tape & Reel versions, provided assembly equipment can accommodate manual or tray-based component feeding.

Q: Are there any compatibility issues between these two packaging formats on the same PCB assembly?

A: No. Once soldered to the PCB, both packaging variants produce identical solder joints and electrical connections. Packaging differences affect only the supply chain and assembly process, not the final assembled product.

Q: What is the significance of the MSL 1 rating for these connectors?

A: MSL 1 indicates unlimited moisture sensitivity, meaning these components do not require special moisture control during storage or handling. Standard warehouse conditions are acceptable without desiccant packaging or controlled humidity environments.

Q: Are both parts ROHS3 compliant?

A: Yes. Both QTH-020-03-L-D-DP-A-TR and QTH-020-03-L-D-DP-A meet ROHS3 compliance requirements, confirming restriction of hazardous substances in accordance with applicable regulations.

Q: What determines whether a part qualifies as a substitute for the QTH-020-03-L-D-DP-A-TR?

A: Substitutes must match all electrical and mechanical parameters: 40-position differential pair array configuration, 0.020" pitch, 2-row layout, gold contact finish at 10.0µin thickness, surface mount technology, identical board heights, and integrated board guide with ground bus features. Packaging format is the only allowable variation.
