Key Parameters

Substitute Part Grouping Explanation

Substitution of the S1210-152K is determined by strict equivalence across the following critical parameters:

Electrical Parameters: Inductance value (1.5 µH), tolerance (±10%), current rating (532 mA), and DC resistance (570 mOhm Max) must remain identical. The shielded ferrite core construction and frequency characteristics (Q @ 7.9 MHz and self resonant frequency at 110 MHz) define the electrical performance envelope.

Mechanical Parameters: Package designation (1210 / 3225 Metric), surface mount mounting type, and physical dimensions (0.128" L x 0.095" W, height 0.101" max) ensure PCB compatibility and assembly process alignment.

Environmental Parameters: Operating temperature range (-55°C ~ 125°C) and moisture sensitivity level (MSL 1 - Unlimited) establish reliability requirements.

The S1210R-152K qualifies as a direct substitute based on complete alignment with all electrical, mechanical, and environmental parameters specified above.

Parameter Comparison

Engineering Selection Recommendations

The S1210R-152K serves as a direct electrical and mechanical equivalent to the S1210-152K. Both components are manufactured by API Delevan Inc. and maintain identical specifications across inductance, current rating, DC resistance, frequency characteristics, package dimensions, and operating temperature range.

The primary distinction between these parts is regulatory compliance status. The S1210-152K is RoHS non-compliant, while the S1210R-152K achieves ROHS3 compliance. This difference is significant for applications subject to RoHS directives or customer specifications requiring compliant components.

Both parts carry REACH Unaffected status and EAR99 export classification. Moisture sensitivity level is identical at MSL 1 (Unlimited), indicating no special moisture handling requirements during storage or assembly.

Selection between these parts should be based on the specific compliance requirements of the target application and end-use market. Where RoHS compliance is mandated, the S1210R-152K is the appropriate choice. Where RoHS compliance is not a requirement, either part satisfies the electrical and mechanical design criteria.

Frequently Asked Questions (FAQ)

Q: Can the S1210R-152K replace the S1210-152K in existing designs?

A: Yes, from an electrical and mechanical standpoint. The S1210R-152K provides identical inductance (1.5 µH), current rating (532 mA), DC resistance (570 mOhm Max), package dimensions (1210 / 3225 Metric), and operating temperature range (-55°C ~ 125°C). The primary difference is RoHS compliance status. Verify that your application does not specifically require the RoHS non-compliant version before substituting.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution eligibility is determined by matching inductance value, tolerance, current rating, DC resistance, shielding type, core material, package designation, physical dimensions, height, operating temperature range, and frequency characteristics. All these parameters must align between the original and substitute part.

Q: Are there any assembly or PCB layout considerations when switching between these parts?

A: No. Both the S1210-152K and S1210R-152K use identical surface mount package dimensions (0.128" L x 0.095" W, height 0.101" max) and the same 1210 (3225 Metric) footprint. PCB layouts and assembly processes require no modification.

Q: What is the significance of the RoHS compliance difference?

A: RoHS compliance restricts the use of certain hazardous substances in electrical and electronic equipment. The S1210R-152K meets ROHS3 requirements, making it suitable for applications and markets with RoHS mandates. The S1210-152K does not meet these requirements. Selection depends on your regulatory and customer requirements.

Q: Do both parts have the same moisture sensitivity requirements?

A: Yes. Both the S1210-152K and S1210R-152K carry MSL 1 (Unlimited) rating, indicating no special moisture handling, baking, or storage precautions are required.

Q: Are there inventory or lead time differences between these parts?

A: Inventory levels may differ. Verify current stock availability with your supplier, as inventory quantities change based on demand and production schedules.
