Substitute Part Grouping Explanation

Substitution for the QMS-052-01-SL-D-RA-MG-K is determined by equivalence across all critical electrical and mechanical parameters. The substitute part QMS-052-01-SL-D-RA-MG-K-TR maintains identical specifications in the following key areas:

Number of positions (104), pitch (0.025"), row configuration (2), connector type (header with outer shroud contacts), mounting method (surface mount right-angle with through-hole), contact material and finish (gold at 10.0µin thickness), and board height (0.320"). Both parts share the same base product number (QMS-052), series designation (Power Q2™ QMS), and compliance certifications (RoHS3, REACH Unaffected, MSL 1).

The sole difference between these parts is packaging format: the main part is supplied in Tray packaging, while the substitute is supplied in Tape & Reel (TR) format. This distinction affects only procurement and assembly line integration, not component performance or compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both the QMS-052-01-SL-D-RA-MG-K and QMS-052-01-SL-D-RA-MG-K-TR are Active products with full RoHS3 compliance and REACH Unaffected status. Selection between these parts should be based on assembly process requirements and supply chain logistics. Tray packaging is suitable for manual assembly and lower-volume production runs. Tape & Reel packaging is optimized for automated pick-and-place assembly systems and high-volume manufacturing environments. Both parts carry identical electrical performance characteristics and mechanical compatibility with mating connectors from the Power Q2™ QMS series.

Frequently Asked Questions (FAQ)

Q: Are these parts electrically and mechanically identical? A: Yes. Both parts have identical electrical specifications, mechanical dimensions, contact configurations, and performance characteristics. The only difference is packaging format.

Q: Which packaging format should I select for my application? A: Tray packaging is appropriate for manual assembly, prototyping, and low-volume production. Tape & Reel packaging is required for automated assembly lines using pick-and-place equipment.

Q: Can I use these parts interchangeably in my design? A: Yes, from a component perspective. The physical connector specifications are identical. Verify that your assembly process can accommodate the selected packaging format.

Q: Do both parts meet the same compliance standards? A: Yes. Both parts are RoHS3 compliant, REACH Unaffected, and carry MSL 1 (Unlimited) moisture sensitivity rating.

Q: What is the significance of the "-TR" suffix? A: The "-TR" suffix designates Tape & Reel packaging format, which is standard for automated assembly processes. The base component specifications remain unchanged.
