MF1P4101DUD/02V Equivalent & Substitute Parts

Part Overview

The MF1P4101DUD/02V is an RFID Transponder IC manufactured by NXP USA Inc., operating at 14.66MHz and compliant with ISO 14443 and MIFARE standards. This component is classified as obsolete, indicating discontinuation from active production. The die-level package format (Wafer) is designed for integration into larger assemblies or custom packaging solutions. Identifying equivalent substitute parts is necessary due to the obsolete status, which may impact long-term availability and supply chain continuity for new designs or production runs.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MF1P4101DUD/02V is determined by the following critical parameters:

• Frequency Compatibility: 14.66MHz operation is mandatory for RF protocol alignment
• Standards Compliance: ISO 14443 and MIFARE standards ensure protocol-level interoperability
• Package Format: Die (Wafer) configuration is required for direct integration compatibility
• Operating Temperature Range: The substitute must support the minimum required temperature envelope
• Regulatory Compliance: RoHS and REACH status must meet or exceed the original specification

The MF1P4201DUD/00Z qualifies as a manufacturer-recommended substitute based on matching frequency, standards compliance, and regulatory certifications. However, the substitute operates at an extended temperature range (-25°C ~ 85°C) and differs in product status (Active vs. Obsolete) and packaging format (Tray vs. Wafer supplier package).

Parameter Comparison

Engineering Selection Recommendations

The MF1P4201DUD/00Z is the manufacturer-designated substitute for the obsolete MF1P4101DUD/02V. Selection of this substitute is supported by:

• Active Product Status: The substitute maintains active production status, ensuring ongoing availability and supply chain stability
• Regulatory Alignment: Both parts maintain REACH Unaffected status, confirming compliance with chemical substance regulations
• Frequency and Standards Match: Identical 14.66MHz operation and MIFARE standard compliance ensure RF protocol compatibility
• Extended Temperature Range: The substitute's expanded operating range (-25°C ~ 85°C) provides broader environmental tolerance compared to the original specification (-25°C ~ 70°C)

For applications requiring the original -25°C ~ 70°C temperature envelope, the extended range of the substitute does not introduce incompatibility; it represents an enhancement. Die-level package compatibility is maintained for integration into custom packaging or assembly configurations.

Frequently Asked Questions (FAQ)

Q: Why is the MF1P4101DUD/02V classified as obsolete? A: The product status reflects discontinuation from active manufacturing by NXP USA Inc. Obsolete classification typically indicates end-of-life status and reduced availability from standard distribution channels.

Q: Can the MF1P4201DUD/00Z directly replace the MF1P4101DUD/02V in existing designs? A: Yes, at the die level. Both components operate at 14.66MHz and comply with MIFARE standards. However, integration into final packaging or assembly must account for any design-specific requirements tied to the original part's specifications.

Q: What is the significance of the extended temperature range in the substitute? A: The MF1P4201DUD/00Z operates from -25°C ~ 85°C, compared to the original -25°C ~ 70°C. This extended range does not create incompatibility; it indicates the substitute can function across a broader thermal envelope, which may benefit applications with demanding environmental conditions.

Q: Are there differences in packaging that affect integration? A: Both parts are supplied as die in wafer format. The MF1P4201DUD/00Z is packaged in Tray format by the supplier, while the original was packaged in a different format. For die-level integration, this distinction affects handling and storage procedures but not functional compatibility.

Q: What regulatory certifications apply to the substitute? A: The MF1P4201DUD/00Z maintains REACH Unaffected status, matching the original part. RoHS compliance status for the substitute was not specified in the available data; verification with the manufacturer or distributor is recommended for applications with explicit RoHS requirements.
