Key Parameters

Substitute Part Grouping Explanation

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

• Number of Positions: 180
• Pitch: 0.020" (0.50mm)
• Number of Rows: 2
• Connector Type: Header, Outer Shroud Contacts
• Mounting Type: Surface Mount
• Contact Finish: Gold
• Contact Finish Thickness: 3.00µin (0.076µm)
• Height Above Board: 0.160" (4.06mm)
• Mated Stacking Heights: 5mm
• Features: Board Guide, Ground Bus (Plane)
• Series: Q Strip® QTH
• Base Product Number: QTH-090

The only allowable variation is packaging format. The primary part is supplied in Tape & Reel (TR) format. Substitute parts may be supplied in alternative packaging (such as Tray) provided all other electrical and mechanical specifications remain identical.

Parameter Comparison

Engineering Selection Recommendations

Both the QTH-090-01-F-D-A-TR and QTH-090-01-F-D-A are active production parts manufactured by Samtec Inc. with identical electrical and mechanical specifications. Selection between these parts is based on packaging requirements and inventory availability.

The QTH-090-01-F-D-A-TR in Tape & Reel format is suitable for automated assembly processes requiring continuous reel feeding. The QTH-090-01-F-D-A in Tray packaging is suitable for manual assembly, kit builds, or applications where reel format is not required.

Both parts meet ROHS3 compliance and carry MSL 1 rating, indicating no moisture sensitivity restrictions. Selection should be based on assembly process requirements and supply chain logistics rather than technical performance, as all functional and mechanical parameters are equivalent.

Frequently Asked Questions (FAQ)

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

A: Yes. Both parts are electrically and mechanically identical. The only difference is packaging format: Tape & Reel (TR) versus Tray. Direct substitution is valid provided the receiving assembly process can accommodate the alternative packaging format.

Q: What is the significance of the "-TR" suffix in QTH-090-01-F-D-A-TR?

A: The "-TR" suffix designates Tape & Reel packaging. Removal of this suffix indicates Tray packaging. All other specifications remain unchanged.

Q: Are there any performance differences between these two parts?

A: No. Both parts have identical electrical performance, mechanical dimensions, contact specifications, and compliance certifications. Performance is determined by the base product number QTH-090 and configuration code, not by packaging format.

Q: Which part should be selected for high-volume automated assembly?

A: The QTH-090-01-F-D-A-TR in Tape & Reel format is optimized for automated pick-and-place assembly processes. Reel format enables continuous feeding and reduces manual handling.

Q: Which part should be selected for low-volume or manual assembly?

A: The QTH-090-01-F-D-A in Tray packaging is suitable for manual assembly, prototyping, or low-volume production where reel format is not required.

Q: Do both parts meet the same compliance standards?

A: Yes. Both parts are ROHS3 compliant and carry MSL 1 rating. Compliance certifications are identical.

Q: What is the pitch specification for these connectors?

A: The pitch is 0.020" (0.50mm), indicating 0.50mm center-to-center spacing between contact positions across the 180-position, 2-row configuration.
