ERJ-MP2KF2M0U Equivalent & Substitute Parts

Part Overview

The ERJ-MP2KF2M0U is a 2 mOhms ±1% 0.5W chip resistor in 1206 (3216 Metric) package manufactured by Panasonic Electronic Components. This metal element current sense resistor is designed for automotive applications with AEC-Q200 qualification and moisture resistance. The part is currently obsolete, making equivalent substitutes necessary for ongoing production and maintenance applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the ERJ-MP2KF2M0U is determined by the following critical parameters:

• Resistance value: 2 mOhms
• Tolerance: ±1%
• Package: 1206 (3216 Metric)
• Composition: Metal Element
• Moisture Sensitivity Level: 1 (Unlimited)
• RoHS compliance: ROHS3 Compliant

The identified substitutes meet these core requirements. Power rating differences (0.5W vs. 1W) represent an upgrade path where higher power-rated components maintain backward compatibility in the same package footprint. All substitutes are active products with current manufacturing status, addressing the obsolescence of the original part.

Parameter Comparison

Engineering Selection Recommendations

Both CSNL1206FT2L00 and CRF1206-FZ-R002ELF are active production alternatives to the obsolete ERJ-MP2KF2M0U.

The CRF1206-FZ-R002ELF from Bourns maintains AEC-Q200 automotive qualification, matching the original part's automotive-grade specification. This part is recommended for applications requiring automotive compliance continuity.

The CSNL1206FT2L00 from Stackpole provides an active alternative with identical core electrical parameters and RoHS compliance. This option is suitable for non-automotive applications or where automotive qualification is not a requirement.

Both substitutes feature 1W power ratings, providing increased thermal margin compared to the original 0.5W specification. Both maintain the same 1206 package footprint and metal element composition, ensuring PCB layout compatibility.

Frequently Asked Questions (FAQ)

Q: Can CSNL1206FT2L00 or CRF1206-FZ-R002ELF be used as direct replacements for ERJ-MP2KF2M0U?

A: Both parts are electrically compatible as direct replacements. They share identical resistance (2 mOhms), tolerance (±1%), package (1206), and composition (metal element). The higher power rating (1W vs. 0.5W) represents an upgrade that maintains backward compatibility.

Q: What is the difference between the two substitute options?

A: CRF1206-FZ-R002ELF includes AEC-Q200 automotive qualification, matching the original part's automotive specification. CSNL1206FT2L00 does not carry automotive qualification. Both are ROHS3 compliant and have unlimited moisture sensitivity rating.

Q: Are there package footprint differences?

A: All three parts use the 1206 (3216 Metric) package. Dimensional variations are minor (length 3.18-3.20mm, width 1.60-1.65mm, height 0.031-0.045"). These differences do not affect PCB layout compatibility.

Q: What about temperature range differences?

A: The original ERJ-MP2KF2M0U operates from -65°C to 170°C. Both substitutes operate from -55°C to 170°C. The upper temperature limit is identical; the lower limit difference is 10°C. Verify application requirements if operation below -55°C is necessary.

Q: Which substitute should I choose for automotive applications?

A: CRF1206-FZ-R002ELF is qualified to AEC-Q200 and is the appropriate choice for automotive applications requiring this certification.
