Key Parameters

Substitute Part Grouping Explanation

The S1721-06R has one manufacturer-recommended substitute: S1721-46R. Substitution eligibility is determined by the following critical parameters:

• Dimensional Compatibility: Width (0.042"), height (0.088"), and length within acceptable tolerance
• Material & Plating: Stainless steel with tin plating at 3.00µm thickness
• Attachment Method: Solder-based surface mount
• Operating Temperature: -40°C to 125°C range
• Series Alignment: EZ BoardWare product line
• Electrical Function: RFI shield clip for RF and wireless applications

The S1721-46R meets all substitution criteria while offering improved product status and compliance characteristics.

Parameter Comparison

Engineering Selection Recommendations

The S1721-46R is the direct substitute for the obsolete S1721-06R. Both components share identical dimensional specifications, material composition, plating characteristics, and operating temperature ranges. The primary distinctions are product status and regulatory compliance.

The S1721-46R is currently active in production with ROHS3 compliance, whereas the S1721-06R is obsolete and RoHS non-compliant. For new designs or ongoing procurement, the S1721-46R is the appropriate selection. The minimal length variance (0.007" or 0.17mm) falls within standard mechanical tolerances for shield clip applications and does not affect functional performance in RF and wireless circuit configurations.

Frequently Asked Questions (FAQ)

Q: Can S1721-46R be used as a direct replacement for S1721-06R in existing designs?

A: Yes. The S1721-46R maintains dimensional and functional equivalence with the S1721-06R. The length difference of 0.007" (0.17mm) is within acceptable mechanical tolerance for shield clip applications and does not compromise electromagnetic shielding performance.

Q: What is the primary reason for substitution?

A: The S1721-06R is obsolete. The S1721-46R is the manufacturer-recommended active equivalent, ensuring continued availability and supply chain reliability.

Q: Are there compliance differences between these parts?

A: Yes. The S1721-46R is ROHS3 compliant, while the S1721-06R is RoHS non-compliant. For applications subject to RoHS regulations, the S1721-46R is required.

Q: Do the packaging formats differ?

A: The S1721-06R packaging is unspecified in available data. The S1721-46R is supplied in Tape & Reel (TR) format, which is standard for high-volume surface-mount assembly operations.

Q: Are the operating temperature ranges identical?

A: Yes. Both parts operate across -40°C to 125°C, ensuring thermal performance equivalence in RF and wireless applications.

Q: What is the base product number for this series?

A: The base product number is S1721, which identifies the shield clip family within the EZ BoardWare series.
