Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the QTH-090-02-F-D-A-TR are identified based on electrical and mechanical parameter equivalence. The critical parameters that determine substitutability are:

• 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: 0.286" (7.26mm)
• Mated stacking heights: 8mm
• Features: Board Guide, Ground Bus (Plane)
• Series: Q Strip® QTH
• RoHS Status: ROHS3 Compliant
• MSL: 1 (Unlimited)

The QTH-090-02-F-D-A-TR differs from its substitute only in packaging format. The main part is supplied in Tape & Reel (TR) format, while the substitute is supplied in Tray format. Both parts share identical connector specifications and are suitable for direct substitution in applications where packaging format does not impose constraints.

Parameter Comparison

Engineering Selection Recommendations

Both the QTH-090-02-F-D-A-TR and QTH-090-02-F-D-A are active production parts with identical ROHS3 compliance and MSL 1 ratings. Selection between these parts depends on procurement and assembly requirements. The Tape & Reel format (TR) is optimized for automated pick-and-place assembly operations, while the Tray format is suitable for manual assembly or lower-volume applications. Both formats contain the same connector component with no electrical or mechanical differences. Compliance certifications and regulatory status are equivalent across both packaging options.

Frequently Asked Questions (FAQ)

Q: Can QTH-090-02-F-D-A be used as a direct replacement for QTH-090-02-F-D-A-TR?

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

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

A: Tape & Reel (TR) packaging supplies components on a continuous carrier tape wound on a reel, optimized for automated assembly equipment. Tray packaging supplies components in a static tray format, typically used for manual assembly or lower-volume production runs. Both formats contain identical components.

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

A: No. Both QTH-090-02-F-D-A-TR and QTH-090-02-F-D-A carry identical ROHS3 compliance, MSL 1 rating, and regulatory certifications. Compliance status is independent of packaging format.

Q: What are the key electrical parameters that define substitutability for this connector?

A: The 180-position count, 0.020" (0.50mm) pitch, 2-row configuration, gold contact finish at 3.00µin thickness, and outer shroud contact design are the defining electrical and mechanical parameters. Any substitute must match all these specifications.

Q: Can these parts be used interchangeably in high-volume automated assembly?

A: The Tape & Reel format (QTH-090-02-F-D-A-TR) is the standard choice for high-volume automated assembly due to compatibility with pick-and-place equipment. The Tray format (QTH-090-02-F-D-A) may require manual feeding or alternative handling procedures depending on assembly line configuration.
