Key Parameters

Substitute Part Grouping Explanation

Substitution within the QTH-090 connector family is determined by the following critical parameters that must remain constant:

• 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: 0.600" (15.24mm)
• Mated stacking heights: 16mm
• Features: Board Guide, Ground Bus (Plane)

Variations in packaging format (Tape & Reel versus Tray) do not affect electrical or mechanical compatibility and permit substitution between QTH-090-04-F-D-A-TR and QTH-090-04-F-D-A.

Parameter Comparison

Engineering Selection Recommendations

Both QTH-090-04-F-D-A-TR and QTH-090-04-F-D-A are active production parts with ROHS3 compliance and identical electrical and mechanical specifications. Selection between these parts is determined by packaging requirements and supply availability. The Tape & Reel format (QTH-090-04-F-D-A-TR) is suitable for automated assembly processes, while the Tray format (QTH-090-04-F-D-A) accommodates alternative handling and storage methods. Both parts carry MSL 1 rating, indicating no moisture sensitivity restrictions during storage and handling.

Frequently Asked Questions (FAQ)

Q: Can QTH-090-04-F-D-A be used in place of QTH-090-04-F-D-A-TR?

A: Yes. Both parts are electrically and mechanically identical. The difference is packaging format only: Tape & Reel versus Tray. Substitution is valid provided assembly processes accommodate the alternative packaging.

Q: What determines compatibility between these connector variants?

A: Compatibility is maintained when the following parameters remain constant: 180 positions, 0.020" pitch, 2 rows, gold contact finish at 3.00µin thickness, 0.600" height above board, and identical features (Board Guide, Ground Bus). Packaging format does not affect compatibility.

Q: Are there compliance differences between the two parts?

A: No. Both parts are ROHS3 compliant with MSL 1 rating and identical ECCN and HTSUS classifications.

Q: Which packaging format should be selected for high-volume production?

A: Tape & Reel (QTH-090-04-F-D-A-TR) is standard for automated pick-and-place assembly. Tray format (QTH-090-04-F-D-A) is selected when manual handling or alternative assembly equipment is required.
