SC62CB-220 Equivalent & Substitute Parts

Part Overview

The SC62CB-220 is a 22 µH shielded surface mount inductor manufactured by Signal Transformer, rated for 1.17 A continuous current with a maximum DC resistance of 188mOhm. This component is classified as Active product status and is ROHS3 compliant with unlimited moisture sensitivity rating.

Substitute parts become necessary when the SC62CB-220 reaches end-of-life inventory depletion, when design requirements mandate alternative shielding configurations, or when sourcing from alternative manufacturers is required for supply chain optimization.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SC62CB-220 is determined by the following mandatory parameters:

• Inductance value: 22 µH (exact match required)
• Tolerance: ±20% (exact match required)
• Mounting type: Surface Mount (exact match required)
• Inductance test frequency: 100 kHz (exact match required)
• Packaging: Tape & Reel (TR) (exact match required)
• RoHS compliance: ROHS3 Compliant (minimum requirement)

Acceptable variation ranges for substitute parts:

• Current Rating: minimum 1.1 A (within 94% of original 1.17 A rating)
• DC Resistance: maximum 200mOhm (within 106% of original 188mOhm)
• Operating Temperature: minimum -40°C to 125°C lower bound
• Shielding: both shielded and unshielded configurations qualify based on application requirements

Parameter Comparison

Engineering Selection Recommendations

B82472G4223M000 is the primary substitute for new designs. This part maintains shielded configuration matching the SC62CB-220, carries Active product status, and operates within the required temperature range. DC resistance of 200mOhm remains within acceptable tolerance variance. Current rating of 1.1 A satisfies applications where load current does not exceed this threshold.

B82471A1223M000 qualifies as a secondary substitute only for applications where electromagnetic shielding is not a circuit requirement. This part carries Not For New Designs status and features unshielded construction. The superior operating temperature range (-55°C ~ 150°C) and lower DC resistance (180mOhm) may benefit specific thermal or efficiency-critical applications, but product lifecycle status restricts its use to legacy system maintenance or inventory transition scenarios.

Frequently Asked Questions (FAQ)

Q: Can B82471A1223M000 replace SC62CB-220 in shielded circuit applications?

A: No. B82471A1223M000 is unshielded. Applications requiring electromagnetic containment or noise isolation must use B82472G4223M000, which maintains shielded construction.

Q: What is the current rating difference between SC62CB-220 and its substitutes?

A: SC62CB-220 is rated 1.17 A. B82472G4223M000 is rated 1.1 A (94% of original). B82471A1223M000 is rated 1.11 A (95% of original). Substitutes are suitable for applications where continuous current does not exceed 1.1 A.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. Both B82471A1223M000 and B82472G4223M000 are ROHS3 compliant, matching the SC62CB-220 compliance status.

Q: What is the significance of Product Status "Not For New Designs" for B82471A1223M000?

A: This designation indicates the manufacturer does not recommend this part for new circuit designs. It is suitable only for replacement in existing systems or legacy applications. New designs should use B82472G4223M000.

Q: How do DC resistance values affect substitution?

A: SC62CB-220 specifies 188mOhm maximum. B82472G4223M000 is 200mOhm (6% higher). B82471A1223M000 is 180mOhm (5% lower). Higher resistance increases power dissipation; lower resistance reduces it. Selection depends on thermal budget and efficiency requirements of the application.

Q: Are package dimensions interchangeable?

A: All three parts use Tape & Reel (TR) packaging and surface mount mounting type. Physical dimensions vary: SC62CB-220 is 6.30mm x 6.20mm x 2.50mm; B82471A1223M000 is 6.10mm x 5.60mm x 4.90mm; B82472G4223M000 is 7.30mm x 7.30mm x 4.60mm. PCB layout must accommodate these dimensional differences.
