Substitute Part Grouping Explanation

Substitute parts for the S1812-563K are identified based on strict equivalence across all critical electrical and mechanical parameters. The substitution logic is based on the following key criteria:

Electrical Parameters (Must Match):

• Inductance value: 56 µH with ±10% tolerance
• Current rating: 235 mA minimum
• DC resistance: 3.6 Ohm maximum
• Q factor: 50 @ 2.5 MHz
• Self resonant frequency: 8 MHz
• Core material: Ferrite
• Shielding: Shielded configuration

Mechanical Parameters (Must Match):

• Package type: 1812 (4532 Metric)
• Physical dimensions: 0.177" L x 0.126" W (4.50mm x 3.20mm)
• Height seated maximum: 0.134" (3.40mm)
• Mounting type: Surface Mount
• Tape & Reel packaging format

Environmental Parameters (Must Match):

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

Parts meeting all these criteria are classified as direct electrical and mechanical equivalents suitable for component substitution in circuit designs.

Parameter Comparison

Engineering Selection Recommendations

Both the S1812-563K and S1812R-563K are electrically and mechanically equivalent components from API Delevan Inc. All critical inductance, current, resistance, frequency, and thermal parameters are identical. Both parts are in active production status and support the same 1812 (4532 Metric) surface mount package with identical physical dimensions and mounting characteristics.

The primary distinction between these parts is regulatory compliance status. The S1812R-563K carries ROHS3 compliance certification, while the S1812-563K is RoHS non-compliant. Selection between these parts should be based on the specific regulatory and compliance requirements of the end application and target market. Both parts maintain identical electrical performance and mechanical compatibility for circuit design purposes.

Frequently Asked Questions (FAQ)

Q: Can S1812R-563K be used as a direct replacement for S1812-563K in existing designs?

A: Yes. The S1812R-563K is electrically and mechanically equivalent to the S1812-563K. All inductance, current rating, DC resistance, frequency response, and thermal specifications are identical.
