Key Parameters

Substitute Part Grouping Explanation

Substitution for the QFS-026-01-SL-D-RA-PC4-K is determined by strict equivalence across all electrical and mechanical parameters. The identified substitute maintains identical specifications in connector type, position count, pitch, mounting configuration, contact finish, and compliance certifications. The only distinction between the main part and its substitute is the packaging format. Substitution is valid when the following parameters are identical:

• Connector Type: Receptacle, Center Strip Contacts
• Number of Positions: 60 (52 + 8 Power)
• Pitch: 0.025" (0.64mm)
• Number of Rows: 2
• Mounting Type: Surface Mount, Right Angle
• Contact Finish: Gold with 10.0µin thickness
• Series: Power Q2™ QFS
• RoHS Status: ROHS3 Compliant
• MSL: 1 (Unlimited)

Parameter Comparison

Engineering Selection Recommendations

Both QFS-026-01-SL-D-RA-PC4-K and QFS-026-01-SL-D-RA-PC4-K-TR are Active products with ROHS3 compliance and MSL 1 rating. Selection between these parts should be based on manufacturing and assembly requirements. The Tray packaging format (QFS-026-01-SL-D-RA-PC4-K) is suitable for manual handling and lower-volume assembly operations. The Tape & Reel format (QFS-026-01-SL-D-RA-PC4-K-TR) is optimized for automated pick-and-place assembly processes and high-volume production environments. Both parts are electrically and mechanically interchangeable and meet identical compliance standards.

Frequently Asked Questions (FAQ)

Q: Are QFS-026-01-SL-D-RA-PC4-K and QFS-026-01-SL-D-RA-PC4-K-TR electrically identical?

A: Yes. Both parts are identical in all electrical specifications, including connector type, position count, pitch, contact finish, and gold plating thickness. They differ only in packaging format.

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

A: Tray packaging is used for manual component handling and lower-volume assembly. Tape & Reel packaging is designed for automated pick-and-place equipment and high-volume manufacturing. The component itself is identical in both formats.

Q: Can I substitute QFS-026-01-SL-D-RA-PC4-K-TR for QFS-026-01-SL-D-RA-PC4-K in my design?

A: Yes, provided your assembly process supports Tape & Reel format. All electrical and mechanical specifications are identical, and both parts carry the same compliance certifications.

Q: Are both parts ROHS3 compliant?

A: Yes. Both QFS-026-01-SL-D-RA-PC4-K and QFS-026-01-SL-D-RA-PC4-K-TR are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating.

Q: What determines substitution eligibility for this connector series?

A: Substitution is valid when connector type, position count, pitch, mounting configuration, contact finish specifications, and compliance certifications remain identical. Packaging format alone does not affect electrical or mechanical compatibility.
