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

Part Overview

The QFS-026-04.25-L-D-PC4-TR is a 60-position rectangular connector receptacle from Samtec Inc.'s Power Q2™ QFS series, designed for surface mount applications with center strip contacts and gold plating. This connector accommodates 52 signal positions plus 8 dedicated power pins, operating at 0.025" (0.64mm) pitch across 2 rows. The part is Active status and ROHS3 compliant, making it suitable for modern electronics manufacturing. Alternative part sourcing becomes necessary due to inventory constraints, supply chain considerations, or packaging format requirements for specific manufacturing workflows.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the QFS-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 dimensions (Height above board, stacking heights)
• Compliance certifications (ROHS3, MSL 1)

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

Parameter Comparison

Engineering Selection Recommendations

Both QFS-026-04.25-L-D-PC4-TR and QFS-026-04.25-L-D-PC4 are Active status components from Samtec Inc. and maintain identical electrical and mechanical specifications. Selection between these parts should be based on packaging requirements and manufacturing process compatibility:

• QFS-026-04.25-L-D-PC4-TR (Tape & Reel): Suitable for high-volume automated pick-and-place assembly operations requiring continuous reel feeding.
• QFS-026-04.25-L-D-PC4 (Tray): Suitable for manual assembly, lower-volume production runs, or manufacturing environments with tray-based component handling systems.

Both parts satisfy ROHS3 compliance and MSL 1 requirements, ensuring compatibility with standard surface mount assembly processes and storage conditions without moisture baking requirements.

Frequently Asked Questions (FAQ)

Q: Can QFS-026-04.25-L-D-PC4 be used as a direct replacement for QFS-026-04.25-L-D-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 the receiving manufacturing process can accommodate tray-based component handling.

Q: Does packaging format affect connector performance or reliability?

A: No. Packaging format affects only material handling, storage, and assembly automation compatibility. Electrical performance, mechanical fit, and reliability characteristics remain identical between the two parts.

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

A: No. Both parts carry identical ROHS3 compliance status and MSL 1 rating. No additional handling or storage procedures are required when substituting between these parts.

Q: What are the mated stacking height options for this connector?

A: The QFS-026 series supports three mated stacking heights: 10mm, 11mm, and 14mm. Selection depends on the mating connector specification and application requirements.

Q: Is the gold contact finish thickness consistent across both parts?

A: Yes. Both QFS-026-04.25-L-D-PC4-TR and QFS-026-04.25-L-D-PC4 maintain 10.0µin (0.25µm) contact finish thickness, ensuring consistent electrical contact resistance and durability.
