Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the S1210-151K is determined by strict equivalence across the following critical parameters:

Electrical Specifications: Inductance value (150 nH), inductance tolerance (±10%), current rating (979 mA), DC resistance (200 mOhm maximum), Q factor at 25 MHz (40), and self-resonant frequency (330 MHz) must remain identical.

Mechanical Specifications: Package designation (1210 / 3225 Metric), mounting type (Surface Mount), physical dimensions (0.128" L x 0.095" W / 3.25mm x 2.42mm), seated height (0.101" / 2.57mm maximum), and shielding configuration (Shielded) must match exactly.

Material Specification: Core material (Iron) must be identical.

Environmental Specifications: Operating temperature range (-55°C to 125°C) must be maintained.

The S1210R-151K qualifies as a direct substitute because all electrical, mechanical, material, and environmental parameters are equivalent to the S1210-151K.

Parameter Comparison

Engineering Selection Recommendations

The S1210R-151K serves as a direct electrical and mechanical equivalent to the S1210-151K. Both components are manufactured by API Delevan Inc. and maintain Active product status.

A key distinction exists in regulatory compliance: the S1210-151K is RoHS non-compliant, while the S1210R-151K is RoHS3 compliant. Both parts are REACH Unaffected and classified under ECCN EAR99 and HTSUS 8504.50.8000.

Selection between these parts should be based on regulatory requirements applicable to the end application. Applications requiring RoHS3 compliance mandate use of the S1210R-151K. Applications without RoHS compliance requirements may use either part based on availability and supply chain considerations.

Frequently Asked Questions (FAQ)

Q: What makes S1210R-151K a valid substitute for S1210-151K?

A: The S1210R-151K maintains identical electrical specifications (150 nH inductance, 979 mA current rating, 200 mOhm DCR, 40 Q factor at 25 MHz, 330 MHz self-resonant frequency), mechanical specifications (1210 package, surface mount, identical dimensions and height), core material (iron), and operating temperature range (-55°C to 125°C). All critical parameters for inductor substitution are equivalent.

Q: Are there differences between these two parts?

A: The primary difference is regulatory compliance status. The S1210-151K is RoHS non-compliant, while the S1210R-151K is RoHS3 compliant. Both parts are REACH Unaffected. No electrical or mechanical differences exist.

Q: Can these parts be used interchangeably on the same PCB?

A: Yes. Both parts use identical 1210 (3225 Metric) surface mount packages with matching footprints, dimensions (0.128" L x 0.095" W), and seated height (0.101" maximum). PCB layout and assembly processes require no modification when substituting between these parts.

Q: Which part should be selected for new designs?

A: Selection depends on regulatory requirements. For applications requiring RoHS3 compliance, the S1210R-151K is the appropriate choice. For applications without RoHS compliance mandates, either part may be selected based on supply availability and cost considerations.

Q: Are moisture sensitivity levels identical?

A: Yes. Both the S1210-151K and S1210R-151K are classified as MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.
