Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the QTS-025-02-L-D-A-TR is determined by equivalence across the following critical parameters:

• Connector type and contact configuration (Header, Outer Shroud Contacts)
• Electrical specifications (50 positions, 0.025" pitch, 2-row configuration)
• Physical dimensions (Height above board, mated stacking height)
• Contact material and finish (Gold plating at 10.0µin thickness)
• Mounting technology (Surface Mount)
• Compliance certifications (ROHS3, MSL 1)

The identified substitute differs only in packaging format, maintaining full electrical and mechanical compatibility with the main part.

Parameter Comparison

Engineering Selection Recommendations

Both QTS-025-02-L-D-A-TR and QTS-025-02-L-D-A maintain Active product status and full ROHS3 compliance. Selection between these parts is determined by packaging and supply chain requirements rather than electrical or mechanical performance. The Tape & Reel (TR) packaging of QTS-025-02-L-D-A-TR is optimized for automated assembly processes, while the Tray packaging of QTS-025-02-L-D-A accommodates alternative handling and storage methodologies. Both parts carry MSL 1 rating, indicating no moisture sensitivity restrictions during standard storage and handling.

Frequently Asked Questions (FAQ)

Q: Are QTS-025-02-L-D-A-TR and QTS-025-02-L-D-A electrically identical?

A: Yes. Both parts share identical electrical specifications including 50 positions, 0.025" pitch, 2-row configuration, and gold contact finish at 10.0µin thickness. Substitution is valid from an electrical standpoint.

Q: What is the only difference between these two parts?

A: The packaging format. QTS-025-02-L-D-A-TR is supplied in Tape & Reel format, while QTS-025-02-L-D-A is supplied in Tray format. All other specifications are equivalent.

Q: Can I use QTS-025-02-L-D-A in place of QTS-025-02-L-D-A-TR in my assembly process?

A: Substitution is mechanically and electrically valid. However, packaging format compatibility with your assembly equipment must be confirmed. Tape & Reel format is standard for automated pick-and-place systems, while Tray format requires alternative handling methods.

Q: Are both parts RoHS compliant?

A: Yes. Both QTS-025-02-L-D-A-TR and QTS-025-02-L-D-A are ROHS3 compliant.

Q: What does MSL 1 mean for these connectors?

A: MSL 1 indicates unlimited moisture sensitivity level, meaning these components have no moisture-related storage or handling restrictions and do not require special desiccant packaging or baking procedures prior to assembly.
