Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the QTH-090-04-L-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
• Mounting type: Surface Mount
• Connector type: Header, Outer Shroud Contacts
• Contact finish: Gold at 10.0µin (0.25µm) thickness
• Height above board: 0.600" (15.24mm)
• Mated stacking height: 16mm
• Base product number: QTH-090
• RoHS compliance: ROHS3
• MSL rating: 1 (Unlimited)

The primary distinction between the main part and identified substitutes is packaging format. The QTH-090-04-L-D-A-TR is supplied in Tape & Reel (TR) packaging, while substitute parts may be available in alternative packaging configurations such as Tray. All electrical and mechanical specifications remain identical across packaging variants.

Parameter Comparison

Engineering Selection Recommendations

Both the QTH-090-04-L-D-A-TR and QTH-090-04-L-D-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 rather than functional performance.

The QTH-090-04-L-D-A-TR in Tape & Reel packaging is suitable for high-volume automated assembly processes where reel-fed component handling is standard. The QTH-090-04-L-D-A in Tray packaging accommodates manual assembly workflows or lower-volume production runs. Both parts maintain ROHS3 compliance and unlimited moisture sensitivity rating, ensuring compatibility with standard PCB assembly and storage protocols.

Frequently Asked Questions (FAQ)

Q: Are QTH-090-04-L-D-A-TR and QTH-090-04-L-D-A electrically identical?

A: Yes. Both parts are functionally equivalent with identical pin count (180 positions), pitch (0.020"), row configuration (2 rows), contact finish (gold at 10.0µin thickness), and all electrical specifications.

Q: What is the difference between Tape & Reel and Tray packaging?

A: Tape & Reel (TR) packaging supplies components on continuous carrier tape wound on reels, optimized for automated pick-and-place assembly. Tray packaging supplies components in static-dissipative trays, suitable for manual assembly or lower-volume production environments.

Q: Can I use QTH-090-04-L-D-A as a direct replacement for QTH-090-04-L-D-A-TR?

A: Yes, provided your assembly process accommodates Tray packaging. The component specifications, PCB footprint, and mating interface are identical.

Q: Are both parts RoHS compliant?

A: Yes. Both QTH-090-04-L-D-A-TR and QTH-090-04-L-D-A are ROHS3 compliant.

Q: What is the moisture sensitivity level for these parts?

A: Both parts have MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.

Q: Do these parts require different PCB footprints?

A: No. Both parts share identical mechanical specifications and use the same PCB footprint. Packaging format does not affect board-level integration.
