Key Parameters

Substitute Part Grouping Explanation

The AT88RF04C-MVA1 qualifies as a direct substitute based on the following critical parameters:

• Identical manufacturer (Microchip Technology)
• Identical series designation (CryptoMemory®, CryptoRF®)
• Identical passive technology and 14.66MHz frequency
• Identical read/write memory configuration (4kb user memory)
• Identical ISO 14443 standard compliance
• Identical inlay style and physical dimensions (18.10mm x 8.60mm)
• Identical operating temperature range (-40°C ~ 85°C)
• ROHS3 compliance maintained

The primary distinction is product status: AT88RF04C-MVB1G is obsolete while AT88RF04C-MVA1 is active, with MSL rating difference (1 vs. 3) reflecting manufacturing process updates.

Parameter Comparison

Engineering Selection Recommendations

For new designs and production applications, AT88RF04C-MVA1 is the appropriate selection. The substitute part maintains full functional and electrical equivalence with the obsolete AT88RF04C-MVB1G while offering active product status and current manufacturing support from Microchip Technology. Both parts satisfy ROHS3 compliance and REACH unaffected status requirements. The MSL rating difference reflects standard manufacturing process evolution and does not impact functional compatibility in equivalent operating conditions.

Frequently Asked Questions (FAQ)

Q: Can AT88RF04C-MVA1 directly replace AT88RF04C-MVB1G in existing designs?

A: Yes. Both parts are functionally equivalent across all critical parameters: frequency, memory capacity, standards compliance, operating temperature range, and physical dimensions. The substitute maintains identical electrical and mechanical specifications.

Q: What is the significance of the different MSL ratings?

A: MSL (Moisture Sensitivity Level) 1 indicates unlimited shelf life without moisture control, while MSL 3 requires storage at controlled humidity for 168 hours. This reflects manufacturing process updates and does not affect component performance or compatibility in standard operating environments.

Q: Are there any compliance differences between the two parts?

A: Both parts are ROHS3 compliant and REACH unaffected. Regulatory compliance is maintained across the substitution.

Q: Why is AT88RF04C-MVB1G classified as obsolete?

A: Product obsolescence typically reflects manufacturer discontinuation of production lines. AT88RF04C-MVA1 represents the current active equivalent from Microchip Technology.

Q: Are the physical dimensions identical?

A: Yes. Both parts measure 0.712" L x 0.338" W (18.10mm x 8.60mm) and are inlay style, ensuring mechanical compatibility in existing form factor requirements.
