QTH-020-01-H-D-DP-A-TR Equivalent & Substitute Parts

Part Overview

The QTH-020-01-H-D-DP-A-TR is a 40-position differential pair array connector manufactured by Samtec Inc. in 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 active in production 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 QTH-020-01-H-D-DP-A-TR is determined by the following critical parameters that must remain identical:

• Connector type: Differential Pair Array, Male
• Number of positions: 40
• Pitch: 0.020" (0.50mm)
• Number of rows: 2
• Mounting type: Surface Mount
• Contact finish: Gold at 30.0µin (0.76µm) thickness
• Height above board: 0.160" (4.06mm)
• Mated stacking height: 5mm
• Features: Board Guide, Ground Bus (Plane)
• Series: Q Strip® QTH
• RoHS compliance: ROHS3
• Moisture sensitivity level: 1

The only allowable variation between the main part and substitutes is packaging configuration (Tape & Reel versus Tray). All electrical, mechanical, and environmental specifications must match exactly.

Parameter Comparison

Engineering Selection Recommendations

Both the QTH-020-01-H-D-DP-A-TR and QTH-020-01-H-D-DP-A are active production parts from Samtec Inc. with identical electrical and mechanical specifications. Selection between these parts is determined solely by packaging and supply chain requirements.

The QTH-020-01-H-D-DP-A-TR in Tape & Reel packaging is suitable for high-volume automated assembly operations. The QTH-020-01-H-D-DP-A in Tray packaging accommodates manual assembly processes or lower-volume production runs.

Both parts maintain ROHS3 compliance and MSL 1 rating, ensuring compatibility with standard PCB assembly processes and storage conditions without moisture bake-out requirements.

Frequently Asked Questions (FAQ)

Q: Can QTH-020-01-H-D-DP-A (Tray) be used in place of QTH-020-01-H-D-DP-A-TR (Tape & Reel)?

A: Yes. The parts are electrically and mechanically identical. The difference is packaging only. Tray packaging is suitable for manual pick-and-place or lower-volume assembly. Tape & Reel packaging is optimized for automated high-speed assembly equipment.

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

A: No. Both parts share identical mounting specifications, pitch, position count, and height above board. PCB footprints are interchangeable.

Q: Do both parts require the same storage and handling procedures?

A: Yes. Both parts carry MSL 1 rating, indicating unlimited shelf life without moisture sensitivity concerns. Standard ESD precautions apply to both.

Q: What is the base product number for this connector family?

A: The base product number is QTH-020, which identifies the core connector platform within the Q Strip® QTH series.

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

A: No. Both parts are ROHS3 compliant and carry identical environmental and regulatory certifications.
