Key Parameters

Substitute Part Grouping Explanation

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

• Connector type, position count, and pitch (180 positions at 0.020" spacing)
• Row configuration (2 rows)
• Mounting technology (surface mount)
• Contact material and finish specifications (gold, 50.0µin thickness)
• Physical dimensions (height above board, mated stacking height)
• Electrical and environmental compliance (ROHS3, MSL 1)
• Base product number (QTH-090)

The identified substitute part QTH-090-01-C-D-A differs only in packaging format (Tray versus Tape & Reel). All electrical, mechanical, and compliance parameters remain identical.

Parameter Comparison

Engineering Selection Recommendations

Both QTH-090-01-C-D-A-TR and QTH-090-01-C-D-A are active production parts from Samtec Inc. with identical electrical and mechanical specifications. Selection between these parts is determined by packaging and assembly process requirements:

• QTH-090-01-C-D-A-TR (Tape & Reel packaging) is suitable for automated pick-and-place assembly operations requiring continuous reel feeding.
• QTH-090-01-C-D-A (Tray packaging) is suitable for manual assembly, kit builds, or processes where individual component handling is preferred.

Both parts maintain ROHS3 compliance and MSL 1 rating. No functional or performance differences exist between the two variants.

Frequently Asked Questions (FAQ)

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

A: Yes. Both parts are electrically and mechanically identical. The only difference is packaging format (Tray versus Tape & Reel). Selection depends on assembly process requirements and handling procedures.

Q: What does the "-TR" suffix indicate?

A: The "-TR" suffix designates Tape & Reel packaging, which is standard for automated surface mount assembly. The part without this suffix uses Tray packaging.

Q: Are there any compatibility issues when switching between these two part numbers?

A: No. The connector specifications, contact configuration, pitch, and all electrical parameters are identical. Compatibility is determined solely by your assembly equipment and process requirements.

Q: Do both parts meet the same compliance standards?

A: Yes. Both QTH-090-01-C-D-A-TR and QTH-090-01-C-D-A are ROHS3 compliant with MSL 1 rating. Environmental and regulatory compliance is equivalent.

Q: What is the significance of the 0.020" pitch specification?

A: The 0.020" (0.50mm) pitch defines the center-to-center spacing between adjacent connector positions. This parameter must remain constant for mechanical and electrical compatibility within the Q Strip® QTH series.
