Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed—0327010.LXS, 0327010.UXS, and 0327010.YX2S—are functionally equivalent to the MIC3010.VP for automotive 10 A, 32 V DC blade micro fuse applications. Selection among these parts may be based on:

Product Availability: Inventory levels vary across substitute options. 0327010.YX2S maintains the highest stock level at 3,616 pieces, while 0327010.LXS and 0327010.UXS provide 765 and 994 pieces respectively.

Compliance Status: All parts maintain active production status and full ROHS3 compliance, meeting current regulatory requirements for automotive electrical components.

Series Compatibility: The MIC3010.VP operates within the MICRO3™ series, while substitute parts belong to the MICRO2™ 327 series. Both series share identical electrical ratings, mechanical dimensions, and thermal operating ranges, ensuring direct functional interchangeability in holder-mounted applications.

Frequently Asked Questions (FAQ)

Q: Can 0327010.LXS, 0327010.UXS, or 0327010.YX2S be used as direct replacements for MIC3010.VP?

A: Yes. All three parts meet the critical substitution criteria: 10 A current rating, 32 V DC voltage rating, 1 kA breaking capacity, identical blade micro package dimensions, and -40°C to 125°C operating temperature range. They are mechanically and electrically interchangeable in holder-mounted automotive fuse applications.

Q: What is the difference between the MICRO3™ and MICRO2™ 327 series?

A: Both series share identical electrical and mechanical specifications for this 10 A, 32 V DC application. The series designation reflects internal Littelfuse product line organization but does not affect functional compatibility or performance in the specified circuit.

Q: Are there any differences in DC cold resistance among the substitute parts?

A: DC cold resistance values are provided for substitute parts (0327010.LXS: 7.7 Ohms, 0327010.UXS: 7.7 mOhms, 0327010.YX2S: 0.0077 Ohms) but not for the main part MIC3010.VP. These variations reflect different measurement units or precision specifications within the MICRO2™ 327 series but do not affect substitution eligibility, as all parts maintain the same current-carrying and protection characteristics.

Q: Do all parts require the same holder type?

A: Yes. All parts—MIC3010.VP and the three substitutes—are blade micro fuse elements requiring a compatible micro blade fuse holder. Mechanical dimensions are identical across all parts.

Q: What is the melting I²t specification, and why is it not provided for MIC3010.VP?

A: Melting I²t (89 A²s) is a thermal characteristic indicating the energy required to melt the fuse element. This specification is documented for the MICRO2™ 327 series substitutes but not provided in the MIC3010.VP data. The absence of this specification does not indicate a difference in fuse response or protection characteristics.
