Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the QTH-020-01-F-D-DP-A-TR is determined by equivalence in the following critical parameters:

• 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
• Contact Finish Thickness: 3.00µin (0.076µm)
• Mated Stacking Height: 5mm
• Height Above Board: 0.160" (4.06mm)
• Features: Board Guide, Ground Bus (Plane)
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

The only variable parameter among qualified substitutes is packaging format. The main part is supplied in Tape & Reel (TR) format, while substitute parts may be supplied in alternative packaging such as Tray, provided all electrical and mechanical specifications remain identical.

Parameter Comparison

Engineering Selection Recommendations

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

The QTH-020-01-F-D-DP-A-TR in Tape & Reel format is suitable for high-volume automated assembly operations. The QTH-020-01-F-D-DP-A in Tray packaging is suitable for lower-volume applications or manual assembly processes. Both parts maintain ROHS3 compliance and MSL 1 rating, ensuring compatibility with standard manufacturing and storage protocols.

Frequently Asked Questions (FAQ)

Q: Can QTH-020-01-F-D-DP-A be used as a direct replacement for QTH-020-01-F-D-DP-A-TR?

A: Yes. Both parts are electrically and mechanically identical. The difference is packaging format only. QTH-020-01-F-D-DP-A is supplied in Tray format while QTH-020-01-F-D-DP-A-TR is supplied in Tape & Reel format. Component performance and PCB compatibility are identical.

Q: What is the significance of the "-TR" suffix in the part number?

A: The "-TR" suffix designates Tape & Reel packaging, which is standard for automated pick-and-place assembly. The base part number QTH-020-01-F-D-DP-A without the "-TR" suffix indicates Tray packaging.

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

A: No. Both parts carry identical RoHS3 compliance and MSL 1 rating. No additional testing or qualification is required when substituting between these parts.

Q: What are the key parameters that must match for substitution eligibility?

A: Critical parameters include connector type (Differential Pair Array, Male), position count (40), pitch (0.020"), row configuration (2), mounting type (Surface Mount), contact finish (Gold at 3.00µin thickness), stacking height (5mm), board height (0.160"), and feature set (Board Guide, Ground Bus). All these parameters are identical between the main part and substitute.

Q: Can these connectors be used interchangeably in the same PCB design?

A: Yes. Both parts have identical footprints, mating heights, and electrical characteristics. No PCB redesign or layout modification is required when substituting between QTH-020-01-F-D-DP-A-TR and QTH-020-01-F-D-DP-A.
