Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SRN3010-2R2M is determined by the following critical parameters:

• Inductance Value: 2.2 µH with ±20% tolerance
• Package / Case: 1212 (3030 Metric) surface mount form factor
• Core Type: Ferrite drum core, semi-shielded construction
• Operating Temperature Range: -40°C to 125°C
• Compliance Standards: ROHS3 Compliant, REACH Unaffected

The SRN3010C-2R2M qualifies as a manufacturer-recommended substitute. Both parts share identical inductance specifications, package dimensions, core material, shielding configuration, and operating temperature range. The substitute part maintains full compatibility with the mechanical and electrical interface requirements of the original design while offering improved current handling capability and enhanced performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

The SRN3010C-2R2M is the manufacturer-recommended substitute for the obsolete SRN3010-2R2M. Both components maintain identical mechanical compatibility and electrical interface specifications. The substitute part is currently in active production status, ensuring long-term availability and supply chain continuity.

Both parts satisfy ROHS3 compliance and REACH regulatory requirements. The SRN3010C-2R2M offers enhanced performance margins with higher current rating (2.6 A versus 1.9 A) and improved saturation current (1.8 A versus 1.3 A), providing additional design headroom for applications operating near the original part's current limits.

Selection between these parts depends on application current requirements and design margin preferences. For applications requiring the original 1.9 A rating, the substitute part provides direct functional replacement with superior performance characteristics. The increased DC resistance specification (120 mOhm Max versus 96 mOhm Max) must be evaluated within the context of specific circuit thermal and efficiency requirements.

Frequently Asked Questions (FAQ)

Q: Can the SRN3010C-2R2M be used as a direct replacement for the SRN3010-2R2M?

A: Yes. Both parts share identical inductance values, package dimensions, core material, shielding configuration, and operating temperature range. The substitute part is mechanically and electrically compatible with designs specified for the original component.

Q: What are the key differences between these parts?

A: The SRN3010C-2R2M provides higher current rating (2.6 A versus 1.9 A), improved saturation current (1.8 A versus 1.3 A), and higher DC resistance (120 mOhm Max versus 96 mOhm Max). The substitute part is in active production status, whereas the original part is obsolete.

Q: Are there packaging differences between these parts?

A: Both parts are supplied in the 1212 (3030 Metric) surface mount package with identical physical dimensions and height specifications. The substitute part is available in Cut Tape (CT) and Digi-Reel packaging options.

Q: Do both parts meet the same regulatory and compliance standards?

A: Yes. Both the SRN3010-2R2M and SRN3010C-2R2M are ROHS3 compliant, REACH unaffected, and carry Moisture Sensitivity Level 1 (Unlimited) ratings.

Q: Should I be concerned about the increased DC resistance in the substitute part?

A: The DC resistance increase from 96 mOhm to 120 mOhm must be evaluated within your specific circuit application. For low-current applications or designs with thermal margin, this difference may be negligible. For high-current or thermally constrained applications, conduct circuit analysis to confirm acceptable power dissipation levels.
