Key Parameters

Substitute Part Grouping Explanation

The QFSS-026-04.25-L-D-PT4 has one parametric equivalent substitute: QFSS-026-04.25-L-D-PC4. Both parts share identical electrical and mechanical specifications, including connector type, position count, pitch, row configuration, mounting method, contact finish, stacking height, and board height. The substitution is valid based on the following key parameters:

• Number of Positions: 60 (52 + 8 Power)
• Pitch: 0.025" (0.64mm)
• Number of Rows: 2
• Connector Type: Receptacle, Center Strip Contacts
• Mounting Type: Surface Mount
• Contact Finish: Gold at 10.0µin (0.25µm)
• Features: Board Guide, Ground Bus (Plane), Power Pins (8), Shielded
• Mated Stacking Height: 11mm
• Height Above Board: 0.278" (7.06mm)

The primary difference between these parts is packaging: PT4 denotes Tray packaging, while PC4 denotes alternative packaging. Both maintain full compliance with RoHS3 and REACH requirements.

Parameter Comparison

Engineering Selection Recommendations

Both QFSS-026-04.25-L-D-PT4 and QFSS-026-04.25-L-D-PC4 are Active products with full ROHS3 compliance and REACH Unaffected status. Selection between these parts should be based on packaging requirements and inventory availability. The QFSS-026-04.25-L-D-PC4 offers higher current inventory (998 units versus 833 units). Both parts maintain identical electrical performance, mechanical dimensions, and regulatory compliance. The choice between PT4 and PC4 packaging variants does not affect functional compatibility in the application.

Frequently Asked Questions (FAQ)

Q: Can QFSS-026-04.25-L-D-PC4 be used as a direct replacement for QFSS-026-04.25-L-D-PT4?

A: Yes. Both parts are parametric equivalents with identical electrical and mechanical specifications. The difference is packaging designation only. Both are Active products with full compliance certifications.

Q: What is the difference between PT4 and PC4 packaging designations?
