Key Parameters

Substitute Part Grouping Explanation

Substitution of the 41470C is determined by the following critical parameters:

• Inductance Value: 47 µH (exact match required)
• Current Rating: Minimum 2.2 A (equal or higher acceptable)
• DC Resistance: Maximum 62mOhm (lower values acceptable)
• Type & Shielding: Toroidal, unshielded configuration
• Mounting: Surface mount, nonstandard package
• Frequency Test Point: 10 kHz

The Amgis SH50S-3.0-47 meets these substitution criteria with equivalent inductance, higher current rating, lower DC resistance, and compatible physical form factor.

Parameter Comparison

Engineering Selection Recommendations

The SH50S-3.0-47 from Amgis is a direct functional substitute for the obsolete 41470C. The substitute part provides superior electrical performance with a 0.8 A higher current rating and 12mOhm lower DC resistance, while maintaining identical inductance and test frequency specifications. The extended operating temperature range of -40°C to 125°C provides additional thermal margin compared to the original part's -40°C to 85°C range. Both parts maintain RoHS compliance status, with the substitute achieving ROHS3 certification. The active product status of the SH50S-3.0-47 ensures ongoing availability and supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can the SH50S-3.0-47 be used as a direct replacement for the 41470C?

A: Yes. Both parts share identical inductance values (47 µH), equivalent toroidal unshielded configuration, surface mount packaging, and 10 kHz test frequency. The substitute meets or exceeds all critical electrical parameters of the original part.

Q: What are the key differences between these parts?

A: The SH50S-3.0-47 provides higher current rating (3 A versus 2.2 A), lower DC resistance (50mOhm versus 62mOhm maximum), and extended operating temperature range (-40°C to 125°C versus -40°C to 85°C). The substitute uses iron powder core material and includes ±20% inductance tolerance specification.

Q: Are there packaging considerations for this substitution?

A: Both parts use nonstandard surface mount packages with similar physical dimensions. The SH50S-3.0-47 is supplied in Tape & Reel packaging, while the 41470C packaging format is not specified. Verify mechanical fit and PCB layout compatibility before implementation.

Q: Does the substitute part maintain compliance requirements?

A: Yes. The SH50S-3.0-47 is ROHS3 compliant and REACH unaffected, meeting or exceeding the RoHS compliance status of the original 41470C. Both parts carry EAR99 ECCN classification.
