Key Parameters

Substitute Part Grouping Explanation

Substitute parts within the MM3474 series are qualified as parametric equivalents based on identical electrical and mechanical specifications. All substitute parts share the following critical parameters with the MM3474F05VBE:

• Identical battery protection function for lithium ion/polymer chemistry
• Identical cell count range (3 ~ 5 cells)
• Identical fault protection capabilities (over-current and over-voltage)
• Identical serial interface specification
• Identical operating temperature range (-40°C ~ 85°C)
• Identical surface mount technology and 20-TSSOP package format
• Identical RoHS3 compliance and MSL rating
• Identical manufacturer (Mitsumi Electric Company Ltd)

The MM3474 series variants (MM3474F05VBE, MM3474F03VBE, MM3474G05VBE) are interchangeable for applications requiring multi-cell battery protection with these specifications. Substitution is valid across all three part numbers without functional or mechanical compromise.

Parameter Comparison

Engineering Selection Recommendations

All three parts in the MM3474 series (MM3474F05VBE, MM3474F03VBE, MM3474G05VBE) are qualified for direct substitution in applications requiring multi-cell lithium ion/polymer battery protection. Selection among these equivalents is based on inventory availability and supply chain considerations rather than functional or electrical differences.

All substitute parts maintain Active product status and ROHS3 compliance, ensuring regulatory conformance and long-term availability. The identical MSL rating of 1 (Unlimited) indicates equivalent moisture handling and storage requirements across all variants.

The 20-TSSOP package format and surface mount technology are consistent across all parts, eliminating any printed circuit board layout or assembly process modifications during substitution.

Frequently Asked Questions (FAQ)

Q: Can MM3474F03VBE be used as a direct replacement for MM3474F05VBE?

A: Yes. Both parts are parametric equivalents with identical electrical specifications for battery protection function, cell count range, fault protection capabilities, operating temperature range, and package format. Direct substitution is valid without design modification.

Q: Are there any differences in the 20-TSSOP package dimensions between these parts?

A: No. All three parts use the identical 20-TSSOP (0.173", 4.40mm Width) package format with TSOP-20D supplier device package designation. PCB footprints and assembly processes remain unchanged during substitution.

Q: Do all MM3474 series variants support the same battery chemistry and cell count?

A: Yes. All three parts (MM3474F05VBE, MM3474F03VBE, MM3474G05VBE) support lithium ion and lithium polymer battery chemistry with 3 to 5 cell configurations. Fault protection for over-current and over-voltage conditions is identical across all variants.

Q: What is the significance of the MSL rating for these battery protection ICs?

A: The MSL rating of 1 (Unlimited) indicates these parts have unlimited shelf life and do not require special moisture control during storage or handling. All three substitute parts share this rating, eliminating any moisture sensitivity considerations during component selection or inventory management.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. MM3474F05VBE, MM3474F03VBE, and MM3474G05VBE are all ROHS3 compliant, meeting environmental and regulatory requirements for electronic component manufacturing and use.

Q: Can these parts be used interchangeably in existing designs without PCB modifications?

A: Yes. The identical surface mount package format, pin count, and electrical specifications across all three parts enable direct substitution without PCB layout changes or design modifications.
