Key Parameters

Substitute Part Grouping Explanation

Substitution between QMS-052-01-SL-D-RA-MG-TR and QMS-052-01-SL-D-RA-MG is determined by the following criteria:

Identical Electrical Parameters:

• 104-position configuration with 2-row layout
• 0.025" (0.64mm) pitch spacing
• Gold contact finish at 10.0µin (0.25µm) thickness
• Surface mount, right-angle, through-hole mounting capability
• 0.320" (8.12mm) height above board

Identical Compliance & Environmental:

• RoHS3 compliance
• MSL 1 rating (unlimited moisture sensitivity)
• Active product status
• EAR99 export classification
• HTSUS 8536.69.4040 tariff code

Differentiating Factor:

• Packaging format: Tape & Reel (TR) versus Tray

Both parts share the same base product number (QMS-052) and are functionally interchangeable in circuit design. The packaging difference reflects supply chain and handling requirements only.

Parameter Comparison

Engineering Selection Recommendations

Both parts are Active products with full RoHS3 compliance and MSL 1 environmental rating. Selection between QMS-052-01-SL-D-RA-MG-TR and QMS-052-01-SL-D-RA-MG should be based on packaging requirements and supply chain logistics:

• QMS-052-01-SL-D-RA-MG-TR (Tape & Reel): Suitable for automated assembly processes requiring continuous reel feeding.
• QMS-052-01-SL-D-RA-MG (Tray): Suitable for manual assembly or lower-volume production runs.

Both parts meet identical electrical specifications and regulatory requirements. The choice does not affect circuit performance or reliability.

Frequently Asked Questions (FAQ)

Q: Are these parts electrically identical? A: Yes. Both parts have identical electrical specifications: 104 positions, 0.025" pitch, 2-row configuration, gold contact finish at 10.0µin thickness, and 0.320" height above board.

Q: What is the only difference between these parts? A: Packaging format. QMS-052-01-SL-D-RA-MG-TR is supplied in Tape & Reel format, while QMS-052-01-SL-D-RA-MG is supplied in Tray format.

Q: Can I use the Tray version in place of the Tape & Reel version? A: Yes, from a circuit design and performance perspective. However, assembly process compatibility must be confirmed with your manufacturing equipment specifications.

Q: Do both parts have the same compliance certifications? A: Yes. Both are RoHS3 compliant, have MSL 1 rating, and share the same EAR99 export classification and HTSUS tariff code.

Q: Which part should I select for high-volume automated assembly? A: The Tape & Reel version (QMS-052-01-SL-D-RA-MG-TR) is optimized for automated pick-and-place equipment.

Q: Are there any environmental or storage differences between these parts? A: No. Both parts have identical MSL 1 rating, indicating unlimited moisture sensitivity protection and identical storage requirements.
