Substitute Part Grouping Explanation

Substitution of the S1210-104K is permissible with parts that maintain identical electrical specifications and mechanical compatibility. The critical parameters governing substitution are:

• Inductance Value: 100 µH with ±10% tolerance
• Current Rating: 127 mA minimum
• DC Resistance: 10 Ohm maximum
• Package Footprint: 1210 (3225 Metric) surface mount
• Core Type: Ferrite shielded construction
• Operating Temperature: -55°C to 125°C range
• Frequency Characteristics: Q factor of 40 @ 2.5 MHz and self resonant frequency of 8 MHz

The S1210R-104K is identified as a direct substitute based on matching all electrical parameters, identical package specifications, and equivalent performance characteristics across the specified frequency and temperature ranges.

Parameter Comparison

Engineering Selection Recommendations

The S1210R-104K serves as a direct electrical and mechanical equivalent to the S1210-104K. Both parts are manufactured by API Delevan Inc. and maintain identical inductance, current rating, DC resistance, package dimensions, and frequency characteristics.

The primary distinction between these parts is regulatory compliance status. The S1210R-104K is ROHS3 compliant, whereas the S1210-104K is RoHS non-compliant. Selection between these parts should be based on applicable regulatory requirements for the end application and target market. Both parts are active in production and available in commercial quantities.

For applications where RoHS3 compliance is mandated, the S1210R-104K is the appropriate selection. For applications without RoHS compliance requirements, either part is functionally equivalent. The identical electrical specifications, package footprint, and thermal operating range ensure direct substitution without circuit redesign or performance degradation.

Frequently Asked Questions (FAQ)

Q: Can the S1210R-104K be used as a direct replacement for the S1210-104K in existing designs?

A: Yes. The S1210R-104K is electrically and mechanically identical to the S1210-104K.
