QTH-030-04-L-D-A-TR Equivalent & Substitute Parts

Part Overview

The QTH-030-04-L-D-A-TR is a 60-position rectangular connector header manufactured by Samtec Inc. as part of the Q Strip® QTH series. This surface mount connector features outer shroud contacts with gold plating and is designed for applications requiring high-density interconnection on printed circuit boards. The part is currently in active production status with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Substitute parts are identified when packaging or inventory requirements necessitate alternative sourcing while maintaining identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

The QTH-030-04-L-D-A-TR has one identified substitute: QTH-030-04-L-D-A. Both parts share identical electrical and mechanical specifications across all critical parameters that determine functional compatibility:

• Connector position count and pitch (60 positions at 0.020")
• Row configuration (2 rows)
• Contact material and finish (gold at 10.0µin thickness)
• Physical dimensions (0.600" height above board, 16mm mated stacking height)
• Mounting technology (surface mount with board guide and ground bus features)
• Regulatory compliance (ROHS3, MSL 1)

The substitution difference is limited to packaging format: the main part is supplied in Tape & Reel (TR) format, while the substitute is supplied in Tray format. Both originate from the same manufacturer and base product number (QTH-030).

Parameter Comparison

Engineering Selection Recommendations

Both the QTH-030-04-L-D-A-TR and QTH-030-04-L-D-A are active production parts with identical ROHS3 compliance and regulatory certifications. Selection between these parts is determined by packaging and supply chain requirements rather than electrical or mechanical performance.

The Tape & Reel format (QTH-030-04-L-D-A-TR) is suitable for automated assembly processes requiring continuous reel feeding. The Tray format (QTH-030-04-L-D-A) is appropriate for manual assembly operations or when bulk quantities are preferred without reel packaging. Both formats contain the same connector specification and are interchangeable at the component level once removed from their respective packaging.

Frequently Asked Questions (FAQ)

Q: Are QTH-030-04-L-D-A-TR and QTH-030-04-L-D-A electrically identical?

A: Yes. Both parts have identical electrical specifications including 60 positions, 0.020" pitch, gold contact finish at 10.0µin thickness, and all functional features. The only difference is packaging format.

Q: Can I use QTH-030-04-L-D-A in place of QTH-030-04-L-D-A-TR in my assembly process?

A: Substitution depends on your assembly method. If your process requires Tape & Reel format for automated feeding, the Tray format is not compatible with that specific equipment. If manual placement or alternative feeding methods are available, the Tray format part is functionally equivalent.

Q: Do both parts meet the same compliance standards?

A: Yes. Both parts are ROHS3 compliant with MSL 1 (unlimited moisture sensitivity). They carry identical regulatory certifications and are suitable for the same applications.

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

A: Tape & Reel packaging supplies components on a continuous reel suitable for automated pick-and-place equipment. Tray packaging supplies components in a flat tray format suitable for manual handling or alternative feeding systems. The connector itself is identical in both formats.

Q: Are there inventory differences between these two parts?

A: Yes. The Tape & Reel version (QTH-030-04-L-D-A-TR) has 860 pieces in stock, while the Tray version (QTH-030-04-L-D-A) has 4028 pieces available. Availability may influence sourcing decisions based on project timelines.
