Substitute Part Grouping Explanation

Substitute parts for the S1210R-472G are identified based on strict electrical and mechanical parameter matching within the S1210R series. The primary substitution criteria are:

Critical Parameters (Must Match Exactly):

• Inductance value: 4.7 µH
• Current rating: 402 mA minimum
• DC resistance: 1 Ohm maximum
• Core material: Ferrite
• Shielding: Shielded configuration
• Package / Case: 1210 (3225 Metric)
• Operating temperature range: -55°C to 125°C
• Mounting type: Surface Mount

Allowable Variation Parameters:

• Inductance tolerance: ±2% to ±10% (tolerance band variation permitted)
• Physical dimensions: Minor variations within 1210 package specification
• Q factor and self-resonant frequency: Maintained at specified test conditions

The S1210R-472K qualifies as a substitute part because it maintains all critical electrical parameters and mechanical compatibility while operating within the same temperature and compliance framework.

Parameter Comparison

Engineering Selection Recommendations

Both the S1210R-472G and S1210R-472K are active production parts from API Delevan Inc. with full RoHS3 compliance and REACH unaffected status. Selection between these parts is based on inductance tolerance requirements:

S1210R-472G Selection Criteria:

• Applications requiring ±2% inductance tolerance
• Circuits with tighter inductance value specifications
• Current inventory: 1133 pieces

S1210R-472K Selection Criteria:

• Applications tolerating ±10% inductance tolerance
• Cost-optimized designs where tighter tolerance is not required
• Current inventory: 1704 pieces

Both parts maintain identical electrical performance at rated current (402 mA), DC resistance (1 Ohm maximum), and operating temperature range (-55°C to 125°C). Physical dimensions remain compatible with 1210 (3225 Metric) package specifications and surface mount assembly processes. Compliance certifications are equivalent across both parts.

Frequently Asked Questions (FAQ)

Q: Can S1210R-472K replace S1210R-472G in all applications?

A: S1210R-472K can replace S1210R-472G when the application circuit tolerates ±10% inductance variation. If the circuit design requires ±2% inductance tolerance, S1210R-472K is not suitable. Review circuit specifications for inductance tolerance requirements before substitution.

Q: What is the difference between these two parts?

A: The primary difference is inductance tolerance. S1210R-472G specifies ±2% tolerance, while S1210R-472K specifies ±10% tolerance. All other electrical parameters, current ratings, DC resistance, core material, shielding, temperature range, and package specifications are identical.

Q: Are the physical dimensions identical?

A: Both parts use the 1210 (3225 Metric) package. S1210R-472G dimensions are 0.138" L x 0.105" W (3.51mm x 2.66mm). S1210R-472K dimensions are 0.128" L x 0.095" W (3.25mm x 2.42mm). Height is identical at 0.101" (2.57mm) maximum. Minor dimensional variation is within 1210 package specification and does not affect PCB layout compatibility.

Q: Are both parts RoHS compliant?

A: Yes. Both S1210R-472G and S1210R-472K are ROHS3 compliant with REACH unaffected status. Both parts carry unlimited moisture sensitivity rating (MSL 1).

Q: What is the current rating for both parts?

A: Both parts are rated for 402 mA continuous current with 1 Ohm maximum DC resistance at rated current.

Q: Can these parts be used interchangeably in surface mount assembly?

A: Yes. Both parts are surface mount inductors in identical 1210 (3225 Metric) packages with the same mounting type. Assembly process parameters remain unchanged between the two parts.
