Equivalent & Alternatives
The following parts are listed as comparable options for similar contactless smart card IC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MF1P4201DUD/00 | Same 4 kB memory and SOT500-2 package, but uses 7-byte UID instead of 4-byte NUID; lacks Random ID support. | Preferred where global UID uniqueness is required (e.g., national ID programs), not suitable for GDPR-sensitive deployments requiring anonymized identifiers. | Select MF1P4201DUD/00 only when deterministic UID traceability is mandated and Random ID is unnecessary. |
| MF1PH4231DUD/00 | Identical 4 kB memory and 4-byte NUID, but with 70 pF input capacitance - optimized for compact form factors (key fobs, wearables) rather than standard smart cards. | Required for small-footprint implementations where antenna size limits achievable Q-factor; incompatible with standard Class 1 card antennas tuned for 17 pF. | Choose MF1PH4231DUD/00 exclusively for non-card form factors; MF1P4231DUD/00 remains optimal for ISO/IEC 7816-1 compliant smart cards. |
Compared with MF1P4201DUD/00, MF1P4231DUD/00 provides GDPR-aligned privacy via Random ID and NUID, while MF1PH4231DUD/00 trades antenna compatibility for miniaturization - making MF1P4231DUD/00 the sole choice for standard smart card deployments requiring both regulatory compliance and infrastructure interoperability.
