Key Parameters

Substitute Part Grouping Explanation

Substitution of the QTS-025-02-L-D-A-K is limited to packaging format variations. The identified substitute part QTS-025-02-L-D-A-K-TR differs only in packaging configuration: Tray versus Tape & Reel. All critical electrical and mechanical parameters remain identical, including connector type, position count, pitch, mounting method, contact finish, and physical dimensions. The substitution is valid when packaging format does not impose design or assembly constraints.

Parameter Comparison

Engineering Selection Recommendations

Both QTS-025-02-L-D-A-K and QTS-025-02-L-D-A-K-TR are Active status products with identical ROHS3 compliance and REACH unaffected status. Selection between these parts depends solely on packaging requirements and assembly process compatibility. Tray packaging is suitable for manual handling and lower-volume assembly operations. Tape & Reel packaging is required for automated pick-and-place assembly systems. Both parts carry MSL 1 rating, indicating no moisture sensitivity restrictions during storage or handling.

Frequently Asked Questions (FAQ)

Q: Can QTS-025-02-L-D-A-K-TR be used as a direct replacement for QTS-025-02-L-D-A-K?

A: Yes, provided the assembly process accommodates Tape & Reel packaging. All electrical and mechanical specifications are identical. The only difference is packaging format.

Q: What is the primary reason to substitute between these two part numbers?

A: Packaging format. QTS-025-02-L-D-A-K uses Tray packaging, while QTS-025-02-L-D-A-K-TR uses Tape & Reel packaging. Selection depends on whether automated or manual assembly is employed.

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

A: No. Both parts maintain identical RoHS3 compliance, REACH unaffected status, MSL 1 rating, and ECCN/HTSUS classifications.

Q: Does packaging format affect the connector's electrical or mechanical performance?

A: No. Packaging format is a logistics and assembly consideration only. Electrical and mechanical performance is identical between both part numbers.

Q: What is the pitch specification for this connector family?

A: The pitch is 0.025" (0.64mm), which defines the center-to-center spacing between adjacent contact positions in the 50-position header.
