Substitute Part Grouping Explanation

Substitution eligibility for the QTH-090-01-L-D-A-TR is determined by strict equivalence across the following critical parameters:

• Number of positions: 180
• Pitch specification: 0.020" (0.50mm)
• Number of rows: 2
• Connector type: Header with outer shroud contacts
• Mounting method: Surface mount
• Contact finish material and thickness: Gold at 10.0µin (0.25µm)
• Height above board: 0.160" (4.06mm)
• Mated stacking height: 5mm
• Integrated features: Board guide and ground bus plane
• Compliance certifications: RoHS3, MSL 1

The identified substitute part QTH-090-01-L-D-A differs only in packaging format (Tray versus Tape & Reel). All electrical and mechanical specifications remain identical, making this part functionally equivalent for circuit design and assembly purposes.

Parameter Comparison

Engineering Selection Recommendations

Both the QTH-090-01-L-D-A-TR and QTH-090-01-L-D-A are active production parts from Samtec Inc. with identical electrical and mechanical specifications. Selection between these parts is determined by packaging and supply chain requirements rather than functional performance.

The QTH-090-01-L-D-A-TR in Tape & Reel packaging is optimized for automated pick-and-place assembly operations. The QTH-090-01-L-D-A in Tray packaging is suitable for manual assembly or alternative handling processes. Both parts maintain full RoHS3 compliance and unlimited moisture sensitivity rating, ensuring compatibility with standard PCB assembly workflows and environmental regulations.

Frequently Asked Questions (FAQ)

Q: Can QTH-090-01-L-D-A be used as a direct replacement for QTH-090-01-L-D-A-TR?

A: Yes. Both parts are electrically and mechanically identical. The only difference is packaging format. QTH-090-01-L-D-A uses Tray packaging while QTH-090-01-L-D-A-TR uses Tape & Reel packaging. Selection depends on assembly equipment and supply chain logistics.

Q: What determines substitution eligibility for this connector series?

A: Substitution is valid when all of the following parameters match: position count (180), pitch (0.020"/0.50mm), row configuration (2), connector type (header with outer shroud), mounting method (surface mount), contact finish (gold at 10.0µin), height specifications (0.160" above board, 5mm mated stacking), and integrated features (board guide and ground bus plane).

Q: Are there compliance differences between the two parts?

A: No. Both parts carry identical certifications: RoHS3 compliance, MSL 1 (unlimited), REACH unaffected status, and the same ECCN and HTSUS classifications.

Q: How does packaging affect assembly compatibility?

A: Tape & Reel (TR) packaging is designed for automated surface mount assembly with pick-and-place equipment. Tray packaging is used for manual assembly or alternative handling methods. The connector itself functions identically in both formats.
