Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the QMS-026-09.75-SL-D-A-K is determined by strict equivalence across the following critical parameters:

• Connector type, position count, and pitch (52 positions at 0.025" spacing)
• Row configuration (2 rows)
• Mounting technology (surface mount)
• Contact material and finish specifications (gold plating at 10.0µin thickness)
• Physical dimensions (height above board and mated stacking heights)
• Compliance certifications (RoHS3, REACH status, MSL rating)
• Series designation (Power Q2™ QMS)

The identified substitute differs only in packaging format, which does not affect electrical or mechanical performance in the assembled application. Both the tray and tape & reel packaging options contain identical connector components with identical specifications.

Parameter Comparison

Engineering Selection Recommendations

Both the QMS-026-09.75-SL-D-A-K and QMS-026-09.75-SL-D-A-K-TR are active products with identical electrical and mechanical specifications. Selection between these parts is determined by manufacturing and procurement requirements rather than functional performance.

Tray packaging (QMS-026-09.75-SL-D-A-K) is suitable for manual assembly, lower-volume production, and applications where automated tape feeding is not required. Tape & reel packaging (QMS-026-09.75-SL-D-A-K-TR) is optimized for high-speed automated pick-and-place assembly and high-volume manufacturing environments.

Both parts maintain full RoHS3 compliance, REACH unaffected status, and MSL 1 rating, ensuring compatibility with standard PCB assembly processes and environmental regulations.

Frequently Asked Questions (FAQ)

Q: Can QMS-026-09.75-SL-D-A-K-TR be used as a direct replacement for QMS-026-09.75-SL-D-A-K?

A: Yes. Both parts are electrically and mechanically identical. The only difference is packaging format. The connector component itself, including all electrical and mechanical specifications, is identical between tray and tape & reel versions.

Q: Does packaging format affect connector performance or reliability?

A: No. Packaging format is a supply chain and manufacturing consideration only. Once the connector is removed from its packaging and installed on the PCB, there is no functional difference between parts from tray or tape & reel packaging.

Q: Are there any compatibility issues when switching between tray and tape & reel packaging?

A: No compatibility issues exist at the component level. The decision to switch packaging formats should be based on assembly equipment capability and production volume requirements.

Q: Do both packaging options maintain the same compliance certifications?

A: Yes. Both QMS-026-09.75-SL-D-A-K and QMS-026-09.75-SL-D-A-K-TR carry identical RoHS3 compliance, REACH unaffected status, and MSL 1 rating.

Q: What is the base product number for these connectors?

A: The base product number is QMS-026. Both the tray and tape & reel variants are derived from this base designation with packaging-specific suffixes.
