Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MF1PLUS8001DA4/03 is determined by the following critical parameters:

• Operating frequency: 14.66MHz
• Package type: MOA4, Smart Card Module
• Mounting configuration: Surface Mount
• Standards compliance: ISO 14443 and MIFARE compatibility
• Interface capability: UART support
• Operating temperature range: Minimum -25°C support required
• RoHS and environmental compliance status

The substitute part MF1P4200DA4/00J shares the core frequency, package form factor, and mounting type. However, functional differences exist in device type classification and interface specifications that must be evaluated for application compatibility.

Parameter Comparison

Engineering Selection Recommendations

The MF1P4200DA4/00J is available as an active product from NXP USA Inc., providing supply continuity compared to the Last Time Buy status of the MF1PLUS8001DA4/03. Both components share identical package form factors (MOA4, Smart Card Module) and surface mount configuration, enabling mechanical and electrical compatibility at the board level.

The primary distinction is functional classification: the MF1PLUS8001DA4/03 operates as a transponder (passive tag), while the MF1P4200DA4/00J functions as a reader. This difference requires evaluation against specific application requirements. The MF1P4200DA4/00J supports an extended operating temperature range (-25°C ~ 85°C) compared to the original part (-25°C ~ 70°C), providing broader environmental tolerance.

Both components maintain compliance with MIFARE standards and operate at 14.66MHz. Selection should be based on whether the application requires transponder or reader functionality, and whether the extended temperature range of the substitute part aligns with deployment conditions.

Frequently Asked Questions (FAQ)

Q: Can MF1P4200DA4/00J directly replace MF1PLUS8001DA4/03 in existing designs?

A: Physical and electrical compatibility exists due to identical package type (MOA4), mounting configuration (Surface Mount), and operating frequency (14.66MHz). However, functional compatibility depends on application requirements, as the substitute part is classified as a reader rather than a transponder. Circuit-level integration and firmware compatibility must be evaluated.

Q: What is the significance of the Last Time Buy status for MF1PLUS8001DA4/03?

A: Last Time Buy indicates the manufacturer will no longer produce this part after a specified cutoff date. Identifying substitute parts ensures continued availability for production and support of existing systems.

Q: Are both parts RoHS compliant?

A: The MF1PLUS8001DA4/03 is explicitly ROHS3 compliant. RoHS status for MF1P4200DA4/00J is not specified in the provided data and should be confirmed with the manufacturer if regulatory compliance is required.

Q: How do the operating temperature ranges compare?

A: The MF1PLUS8001DA4/03 operates from -25°C to 70°C, while MF1P4200DA4/00J operates from -25°C to 85°C. The substitute part supports a 15°C higher maximum temperature, which may be advantageous for applications in elevated thermal environments.

Q: What standards do these components support?

A: Both components support MIFARE standards and operate at 14.66MHz. The MF1PLUS8001DA4/03 is certified to ISO 14443, while MF1P4200DA4/00J supports Mifare and NFC standards. Standards alignment should be verified against application requirements.
