Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the QMS-026-01-SL-D-RA-MG-TR 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 orientation and method (surface mount, right angle, through hole)
• Contact material and finish specification (gold plating at 10.0µin thickness)
• Height above board (0.320")
• Series designation (Power Q2™ QMS)
• Compliance certifications (RoHS3, MSL 1)

The identified substitute part QMS-026-01-SL-D-RA-MG differs only in packaging format (Tray versus Tape & Reel). All electrical, mechanical, and environmental specifications remain identical. This substitution is valid for applications where packaging format does not impose constraints on assembly or logistics workflows.

Parameter Comparison

Engineering Selection Recommendations

Both the QMS-026-01-SL-D-RA-MG-TR and QMS-026-01-SL-D-RA-MG maintain Active product status with identical compliance profiles. Selection between these parts should be based on packaging requirements and supply chain constraints:

The Tape & Reel (TR) packaging format of the main part supports automated assembly processes and is suitable for high-volume production environments. The Tray packaging of the substitute part accommodates manual assembly workflows or lower-volume applications. Both parts carry full RoHS3 compliance and MSL 1 rating, ensuring equivalent environmental and regulatory suitability across applications.

Frequently Asked Questions (FAQ)

Q: Can QMS-026-01-SL-D-RA-MG be used as a direct replacement for QMS-026-01-SL-D-RA-MG-TR?

A: Yes. The parts are electrically and mechanically identical. The only difference is packaging format (Tray versus Tape & Reel). Substitution is valid provided assembly equipment and logistics workflows accommodate Tray packaging.

Q: Are there differences in contact reliability or performance between these parts?

A: No. Both parts use identical contact materials, finish specifications (gold at 10.0µin thickness), and mounting configurations. Performance characteristics are equivalent.

Q: What is the significance of the packaging difference?

A: Tape & Reel packaging is optimized for automated pick-and-place assembly. Tray packaging is suitable for manual handling or lower-volume assembly processes. The choice depends on production methodology and equipment compatibility, not electrical performance.

Q: Do both parts meet the same compliance standards?

A: Yes. Both parts are RoHS3 compliant with MSL 1 rating. Regulatory and environmental requirements are identical.

Q: Can these parts be mixed in the same assembly?

A: Yes. Since electrical and mechanical specifications are identical, both parts can be used interchangeably within the same design without functional impact.
