S1721-06 Equivalent & Substitute Parts
Part Overview
The S1721-06 is a Mini RFI Shield Clip manufactured by Harwin Inc., designed for RF and wireless applications. This component is classified as an obsolete product, which necessitates identification of active equivalent parts for continued system design and procurement. The S1721-06 features a stainless steel construction with tin plating and is supplied in bulk packaging (100/bag). Due to its obsolete status, locating functionally equivalent active alternatives is essential for new designs and ongoing production requirements.

Substitute Part Grouping Explanation
Substitution of the S1721-06 is determined by equivalence across the following critical parameters:
- Mechanical Dimensions: Width (0.042"), height (0.088"), and length (0.200" nominal tolerance)
- Material Composition: Stainless steel construction
- Surface Finish: Tin plating at 118.11µin (3.00µm) thickness
- Attachment Method: Solder-based mounting
- Thermal Performance: Operating temperature range of -40°C to 125°C
- Electrical Classification: RF and wireless component category
- Moisture Sensitivity: MSL 1 rating
The S1721-46R qualifies as a direct substitute based on matching these parameters within acceptable engineering tolerances. The primary distinction is packaging format (bulk versus tape & reel) and product status (active versus obsolete).

Engineering Selection Recommendations
The S1721-46R is the qualified substitute for the obsolete S1721-06 based on dimensional and material equivalence. Key selection factors include:
Product Status: The S1721-46R maintains active product status with Harwin Inc., ensuring continued availability and supply chain reliability compared to the obsolete S1721-06.
Compliance Posture: The S1721-46R achieves ROHS3 compliance, whereas the S1721-06 is RoHS non-compliant. For applications subject to RoHS directives, the S1721-46R is the appropriate selection.
Packaging Considerations: The S1721-06 is supplied in bulk packaging (100/bag), while the S1721-46R is supplied in tape & reel format. Procurement and assembly processes must accommodate this packaging difference.
Dimensional Tolerance: The S1721-46R length specification (0.207") represents a 0.007" increase from the S1721-06 (0.200"). This variance falls within typical mechanical tolerance bands for shield clip applications and does not compromise functional performance.
Frequently Asked Questions (FAQ)
Q: Can the S1721-46R directly replace the S1721-06 in existing designs?
A: Yes, the S1721-46R is dimensionally and functionally equivalent to the S1721-06 across all critical parameters: width, height, material composition, plating specification, attachment method, and operating temperature range. The length difference of 0.007" is within acceptable mechanical tolerance for shield clip applications.
Q: What is the primary reason for substitution?
A: The S1721-06 is classified as obsolete. The S1721-46R is an active product from the same manufacturer and series, ensuring ongoing availability and supply chain continuity.
Q: Does the packaging format change affect component performance?
A: No. The change from bulk packaging (100/bag) to tape & reel format does not affect electrical or mechanical performance. This is a procurement and assembly logistics consideration only.
Q: Are there compliance differences between these parts?
A: Yes. The S1721-46R is ROHS3 compliant, while the S1721-06 is RoHS non-compliant. For applications requiring RoHS compliance, the S1721-46R is the mandated selection.
Q: What is the base product number for the S1721-46R?
A: The base product number is S1721, which encompasses the shield clip family within the EZ BoardWare series.
Q: Are the moisture sensitivity levels identical?
A: Yes. Both the S1721-06 and S1721-46R carry an MSL rating of 1 (Unlimited), indicating no moisture sensitivity constraints for storage or handling.
