QFSS-026-04.25-L-D-PC4-TR Equivalent & Substitute Parts

Part Overview

The QFSS-026-04.25-L-D-PC4-TR is a 60-position rectangular connector receptacle manufactured by Samtec Inc. as part of the Q2™ QFSS series. This surface mount connector features center strip contacts with shielding, gold plating, and integrated power pins (8 dedicated power positions plus 52 signal positions). The part is Active status and ROHS3 compliant, making it suitable for high-density interconnect applications requiring reliable signal and power distribution. Equivalent parts may be required due to packaging format availability, inventory constraints, or specific procurement requirements while maintaining identical electrical and mechanical performance.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the QFSS-026-04.25-L-D-PC4-TR is determined by strict equivalence across the following critical parameters:

• Connector type and contact configuration (Receptacle, Center Strip Contacts)
• Position count and power pin allocation (60 total: 52 signal + 8 power)
• Pitch specification (0.025" / 0.64mm)
• Row configuration (2 rows)
• Mounting technology (Surface Mount)
• Contact material and finish (Gold, 10.0µin thickness)
• Mechanical features (Board Guide, Ground Bus, Shielding)
• Electrical stacking height (11mm mated)
• Compliance certifications (ROHS3, MSL 1)

The primary difference between the main part and its substitute is packaging format: Tape & Reel (TR) versus Tray. This distinction affects handling, storage, and automated assembly compatibility but does not alter electrical or mechanical performance.

Parameter Comparison

Engineering Selection Recommendations

Both the QFSS-026-04.25-L-D-PC4-TR and QFSS-026-04.25-L-D-PC4 are Active status products from Samtec Inc. with identical electrical and mechanical specifications. Both achieve ROHS3 compliance and MSL 1 rating, confirming suitability for standard manufacturing and storage environments without moisture sensitivity constraints.

Selection between these parts should be based on assembly process requirements and packaging compatibility. The Tape & Reel format (TR) is optimized for high-volume automated pick-and-place assembly operations. The Tray format is suitable for manual assembly, lower-volume production, or applications where reel-based handling is not required. Electrical performance, signal integrity, and mechanical fit are equivalent across both packaging options.

Frequently Asked Questions (FAQ)

Q: Are QFSS-026-04.25-L-D-PC4-TR and QFSS-026-04.25-L-D-PC4 electrically interchangeable?

A: Yes. Both parts are identical in electrical specification, contact configuration, pitch, position count, and gold plating thickness. They differ only in packaging format.

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

A: Tape & Reel (TR) packaging winds components on a continuous carrier tape suitable for automated assembly equipment. Tray packaging places components in a static tray format for manual handling or alternative assembly processes. Both formats contain the same component.

Q: Can I substitute QFSS-026-04.25-L-D-PC4 (Tray) for QFSS-026-04.25-L-D-PC4-TR (Tape & Reel) in production?

A: Substitution is possible if your assembly process supports tray-based component feeding. Automated pick-and-place systems typically require Tape & Reel format. Manual assembly or alternative handling systems may accommodate tray format.

Q: Are both parts ROHS3 compliant?

A: Yes. Both QFSS-026-04.25-L-D-PC4-TR and QFSS-026-04.25-L-D-PC4 are ROHS3 compliant with MSL 1 rating.

Q: What is the mated stacking height for this connector?

A: The mated stacking height is 11mm for both parts. The height above board is 0.278" (7.06mm).

Q: How many power pins are included in this 60-position connector?

A: This connector includes 8 dedicated power pins and 52 signal positions, totaling 60 positions.
