Substitute Part Grouping Explanation

The QTH-030-02-L-D-A-TR has one identified substitute: QTH-030-02-L-D-A. Both parts are functionally equivalent based on the following critical parameters that determine substitutability:

• Connector type and position count (60-position header, outer shroud contacts)
• Electrical pitch and row configuration (0.020" pitch, 2 rows)
• Contact material and finish specifications (gold plating, 10.0µin thickness)
• Mechanical dimensions (0.286" height above board, 8mm mated stacking height)
• Board-level features (board guide, ground bus plane)
• Compliance certifications (ROHS3, MSL 1)

The sole difference between these parts is packaging format: the main part is supplied in Tape & Reel (TR) format, while the substitute is supplied in Tray format. This distinction affects only logistics and handling, not electrical or mechanical performance.

Parameter Comparison

Engineering Selection Recommendations

Both QTH-030-02-L-D-A-TR and QTH-030-02-L-D-A are active production parts with identical electrical and mechanical specifications. Selection between these parts should be based on packaging requirements and inventory availability:

The Tape & Reel format (QTH-030-02-L-D-A-TR) is optimized for automated assembly processes with current inventory of 1,158 pieces. The Tray format (QTH-030-02-L-D-A) is suitable for manual assembly or lower-volume applications with higher current inventory of 3,589 pieces. Both parts maintain ROHS3 compliance and unlimited moisture sensitivity rating, making them suitable for standard industrial and commercial applications without additional handling precautions.

Frequently Asked Questions (FAQ)

Q: Can QTH-030-02-L-D-A be used as a direct replacement for QTH-030-02-L-D-A-TR?

A: Yes. Both parts are electrically and mechanically identical. The only difference is packaging format. QTH-030-02-L-D-A-TR uses Tape & Reel packaging, while QTH-030-02-L-D-A uses Tray packaging. Component performance and board-level compatibility are unchanged.

Q: What determines compatibility between these connector headers?

A: Compatibility is determined by position count, pitch, row configuration, contact finish, mechanical dimensions, and mounting type. Both parts match on all these parameters, confirming full substitutability.

Q: Does packaging format affect PCB assembly or soldering?

A: Packaging format affects only component handling and feeding into assembly equipment. Tape & Reel format is designed for automated pick-and-place machines, while Tray format is suitable for manual placement or alternative feeding systems. Once soldered to the PCB, both parts are functionally identical.

Q: Are there any compliance differences between the two parts?

A: No. Both parts carry identical ROHS3 compliance certification and MSL 1 rating. They meet the same regulatory and environmental standards.

Q: Which part should I select for high-volume automated assembly?

A: QTH-030-02-L-D-A-TR (Tape & Reel format) is optimized for automated assembly lines. QTH-030-02-L-D-A (Tray format) is better suited for lower-volume or manual assembly processes.
