Substitute Part Grouping Explanation

Substitution eligibility for the MF1P2131DUD/02V is determined by the following critical parameters:

• Frequency compatibility: 14.66MHz operation
• Standards alignment: ISO 14443 and MIFARE protocol support
• Package format: Die configuration in wafer supply format
• Operating temperature range: Minimum -25°C lower bound; upper bound tolerance of 70°C or higher
• Regulatory compliance: ROHS3 and REACH status equivalence

The identified substitute MF1P2231DUD/00Z maintains frequency and standards compatibility while offering extended operating temperature range and active product status. Both parts are supplied as dies in wafer format and meet equivalent regulatory requirements.

Parameter Comparison

Engineering Selection Recommendations

The MF1P2231DUD/00Z is identified as the manufacturer-recommended substitute for the obsolete MF1P2131DUD/02V. Both components operate at identical frequency (14.66MHz) and support MIFARE protocol standards. The substitute offers an extended operating temperature range (-25°C to 85°C versus -25°C to 70°C), providing improved thermal margin for applications requiring higher temperature operation.

The substitute maintains Active product status, ensuring long-term availability and continued manufacturer support. Both parts are supplied in identical die/wafer format, maintaining mechanical and electrical interface compatibility. ROHS3 compliance is confirmed for the main part; regulatory status for the substitute should be verified during procurement for applications with specific compliance requirements.

Frequently Asked Questions (FAQ)
