• Inductance tolerance: ±10%
• Current rating: 84 mA minimum
• DC resistance: 28 Ohm maximum
• Core material: Ferrite
• Shielding type: Shielded

Mechanical Parameters (Must Match):

• Package format: 1812 (4532 Metric)
• Mounting type: Surface Mount
• Physical dimensions: 0.177" L x 0.126" W (4.50mm x 3.20mm)
• Maximum seated height: 0.134" (3.40mm)

Environmental Parameters (Must Match):

• Operating temperature range: -55°C ~ 125°C
• Moisture sensitivity level: 1 (Unlimited)

Substitute parts must maintain identical electrical performance characteristics and physical compatibility to ensure direct replacement capability in existing circuit designs and PCB layouts.

Parameter Comparison

Engineering Selection Recommendations

Both parts maintain active production status and are available in production quantities. The S1812R-564K currently has higher inventory availability at 2598 pieces compared to 901 pieces for the S1812-564K.

Frequently Asked Questions (FAQ)

Q: Can the S1812R-564K be used as a direct replacement for the S1812-564K?

A: Yes. The S1812R-564K is electrically and mechanically equivalent to the S1812-564K. All electrical parameters including inductance, current rating, DC resistance, and frequency characteristics are identical. Physical dimensions and mounting compatibility are identical, enabling direct PCB substitution.

Q: What is the difference between the S1812-564K and S1812R-564K?

A: The primary difference is RoHS compliance status. The S1812-564K is RoHS non-compliant, while the S1812R-564K is ROHS3 compliant. All other specifications, including electrical performance and physical dimensions, are identical.

Q: Are there any performance differences between these parts?

A: No. Both parts deliver identical electrical performance. The inductance value, current rating, DC resistance, Q factor, and self-resonant frequency are the same for both part numbers.

Q: Which part should be selected for new designs?

A: Selection depends on regulatory requirements. For applications requiring RoHS3 compliance, the S1812R-564K is the appropriate choice. For applications without RoHS compliance requirements, either part is suitable based on availability and supply chain considerations.

Q: Are the physical packages identical?

A: Yes. Both parts use the 1812 (4532 Metric) surface mount package with identical dimensions of 0.177" L x 0.126" W (4.50mm x 3.20mm) and maximum seated height of 0.134" (3.40mm). PCB footprints are identical.

Q: What is the operating temperature range for both parts?

A: Both the S1812-564K and S1812R-564K operate across the temperature range of -55°C to 125°C.

Q: Are both parts available in Tape & Reel packaging?

A: Yes. Both parts are supplied in Tape & Reel (TR) packaging format suitable for automated assembly processes.
