Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the QFS-026-01-SL-D-RA-PC4-TR is determined by strict equivalence across the following critical parameters:

• Manufacturer and series consistency (Samtec Inc., Power Q2™ QFS)
• Identical connector type and contact configuration (Receptacle, Center Strip Contacts)
• Exact position count and power pin allocation (60 total: 52 signal + 8 power)
• Matching pitch specification (0.025" / 0.64mm)
• Identical row configuration (2 rows)
• Consistent mounting method (Surface Mount, Right Angle)
• Equivalent contact finish and thickness (Gold, 10.0µin)
• Matching compliance certifications (ROHS3, MSL 1)

The primary distinction between the main part and its substitute relates to packaging format only, with no impact on electrical or mechanical performance.

Parameter Comparison

Engineering Selection Recommendations

Both QFS-026-01-SL-D-RA-PC4-TR and QFS-026-01-SL-D-RA-PC4 are Active status components from Samtec Inc. with identical electrical and mechanical specifications. Selection between these parts should be based on packaging requirements and procurement workflow:

QFS-026-01-SL-D-RA-PC4-TR (Tape & Reel packaging) is suitable for high-volume automated assembly processes requiring continuous reel feed.

QFS-026-01-SL-D-RA-PC4 (Tray packaging) is appropriate for lower-volume applications, manual assembly operations, or when reel handling infrastructure is not available.

Both parts maintain ROHS3 compliance and MSL 1 rating, ensuring compatibility with standard manufacturing and storage protocols.

Frequently Asked Questions (FAQ)

Q: Can QFS-026-01-SL-D-RA-PC4 be used as a direct replacement for QFS-026-01-SL-D-RA-PC4-TR?

A: Yes. Both parts are electrically and mechanically identical. The only difference is packaging format (Tray versus Tape & Reel). Substitution is valid provided your assembly process accommodates the alternate packaging method.

Q: What determines compatibility between these connector variants?

A: Compatibility is determined by matching connector type, position count, pitch, mounting method, contact finish, and compliance certifications. These parts satisfy all criteria for direct substitution.

Q: Are there any performance differences between Tape & Reel and Tray packaging?

A: No. Packaging format affects only handling, storage, and assembly workflow. Electrical performance and mechanical characteristics remain identical.

Q: What is the significance of the 60-position configuration with 8 dedicated power pins?

A: The 8 dedicated power pins provide dedicated current paths separate from the 52 signal positions, reducing crosstalk and enabling higher current distribution in power-critical applications.

Q: Are both parts suitable for high-density interconnect applications?

A: Yes. Both parts feature 0.025" (0.64mm) pitch and center strip contact configuration, supporting high-density signal routing in compact form factors.
