Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MLF2012DR22MTD25 are qualified based on the following critical parameters that determine functional equivalence:

• Inductance value: 220 nH (core electrical specification)
• Current rating: 250 mA minimum (load capacity requirement)
• Package / Case: 0805 (2012 Metric) (mechanical and PCB footprint compatibility)
• Shielding: Shielded (electromagnetic performance requirement)
• Core material: Ferrite (performance and frequency characteristics)
• Operating temperature range: -55°C ~ 125°C (environmental compatibility)
• Mounting type: Surface Mount (assembly process compatibility)

The CV201210-R22K from Bourns Inc. meets all critical substitution criteria. While DC resistance tolerance differs (500mOhm Max versus 300mOhm Max), both values remain within acceptable operating parameters for the 250 mA current rating and do not prevent functional substitution in applications where the MLF2012DR22MTD25 is specified.

Parameter Comparison

Engineering Selection Recommendations

Both the MLF2012DR22MTD25 and CV201210-R22K are active production components with ROHS3 compliance and REACH unaffected status, making them suitable for current design requirements. The MLF2012DR22MTD25 offers tighter DC resistance specification (300mOhm Max) and higher self-resonant frequency (250MHz), while the CV201210-R22K provides tighter inductance tolerance (±10% versus ±20%). Selection between these parts should be based on specific application requirements regarding DC resistance budget and frequency performance characteristics. Both components share identical package dimensions, current ratings, operating temperature ranges, and moisture sensitivity classifications, ensuring mechanical and thermal compatibility in surface mount assembly processes.

Frequently Asked Questions (FAQ)

Q: Can CV201210-R22K be used as a direct replacement for MLF2012DR22MTD25?

A: Yes, the CV201210-R22K qualifies as a functional substitute. Both parts share the same inductance value (220 nH), current rating (250 mA), package (0805 / 2012 Metric), shielding type, core material, and operating temperature range. The primary difference is DC resistance specification (500mOhm Max versus 300mOhm Max), which does not prevent substitution in applications where the MLF2012DR22MTD25 is specified.

Q: What are the key differences between these two parts?

A: The MLF2012DR22MTD25 has lower maximum DC resistance (300mOhm) and higher self-resonant frequency (250MHz). The CV201210-R22K has tighter inductance tolerance (±10% versus ±20%) and higher maximum DC resistance (500mOhm). Both parts are electrically and mechanically compatible for the 0805 package footprint.

Q: Are the physical dimensions identical?

A: Yes. Both parts measure 0.079" L x 0.049" W (2.00mm x 1.25mm) with a maximum seated height of 0.041" (1.05mm), ensuring identical PCB footprint compatibility and assembly process compatibility.

Q: Do both parts meet current environmental and compliance standards?

A: Yes. Both the MLF2012DR22MTD25 and CV201210-R22K are ROHS3 compliant, REACH unaffected, and classified as MSL 1 (Unlimited moisture sensitivity level), meeting current regulatory requirements for electronic component manufacturing and use.

Q: What is the impact of the DC resistance difference on circuit performance?

A: The DC resistance difference (300mOhm versus 500mOhm) affects power dissipation and voltage drop across the inductor at the 250 mA current rating. Applications with strict power budget or thermal constraints should account for this 200mOhm difference when selecting between these parts.
