Key Parameters

Substitute Part Grouping Explanation

Substitution of the MF1P2101DUD/02V is determined by the following critical parameters:

• Operating frequency alignment at 14.66MHz
• Compliance with ISO 14443 and MIFARE standards
• Die package format (wafer supply)
• Manufacturer continuity (NXP USA Inc.)
• Operating temperature range compatibility
• RoHS and REACH compliance status

The identified substitute MF1P2201DUD/00Z maintains frequency and standards alignment while extending the operating temperature range and transitioning to Active product status. Both components are supplied as dies in wafer format by the same manufacturer.

Parameter Comparison

Engineering Selection Recommendations

The MF1P2201DUD/00Z serves as the direct substitute for the obsolete MF1P2101DUD/02V. Selection is justified by:

• Identical 14.66MHz operating frequency and die package format
• Maintained MIFARE standard compliance with extended NFC capability
• Active product status ensuring continued availability and manufacturing support
• Extended operating temperature range (-25°C to 85°C) providing broader environmental tolerance
• Equivalent REACH compliance status
• Same manufacturer (NXP USA Inc.) ensuring design continuity

Applications requiring the original -25°C to 70°C temperature range are fully supported by the substitute's extended -25°C to 85°C specification.

Frequently Asked Questions (FAQ)

Q: Why is the MF1P2101DUD/02V classified as Obsolete? A: The MF1P2101DUD/02V has reached end-of-life status. The MF1P2201DUD/00Z represents the active successor within NXP's MIFARE product line.

Q: Are the die packages interchangeable between MF1P2101DUD/02V and MF1P2201DUD/00Z? A: Both components are supplied as dies in wafer format. Physical die dimensions and electrical interface compatibility must be verified against detailed datasheets for your specific integration method.

Q: Does the extended temperature range of MF1P2201DUD/00Z affect performance in standard applications? A: The extended range (-25°C to 85°C versus -25°C to 70°C) does not degrade performance within the original operating window. Applications are fully supported across both temperature specifications.

Q: What is the difference between the Standards listed for each part? A: MF1P2101DUD/02V specifies ISO 14443 and MIFARE compliance. MF1P2201DUD/00Z adds NFC capability while maintaining MIFARE compatibility, providing expanded protocol support.

Q: Are both parts REACH compliant? A: Yes. Both MF1P2101DUD/02V and MF1P2201DUD/00Z are listed as REACH Unaffected, indicating compliance with REACH regulations.

Q: What is the difference in packaging between the two parts? A: MF1P2101DUD/02V is supplied in wafer format. MF1P2201DUD/00Z is supplied in Tray packaging. Both are die components; packaging format reflects supplier delivery method.
