Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MF1PLUS8031DA4/03 is determined by the following critical parameters:

• Frequency: 14.66MHz operation is mandatory for RF compatibility
• Standards Compliance: ISO 14443 and MIFARE protocol support ensures interoperability
• Package / Case: MOA4 smart card module form factor maintains mechanical compatibility
• Supplier Device Package: PLLMC designation confirms pinout and footprint alignment
• Mounting Type: Surface mount capability required for assembly process compatibility
• Packaging Format: Tape & Reel (TR) format for automated handling

The substitute part MF1P4230DA4/00J meets these core substitution criteria. Both parts share identical frequency, package designation, mounting type, and packaging format. Both are manufactured by NXP USA Inc. and comply with REACH and RoHS requirements.

Parameter Comparison

Engineering Selection Recommendations

The MF1P4230DA4/00J is available as an active product from NXP USA Inc., providing supply continuity for designs currently using the MF1PLUS8031DA4/03. Both parts share identical mechanical packaging (MOA4 smart card module, PLLMC supplier package), mounting type (surface mount), and distribution format (Tape & Reel).

The substitute part demonstrates an extended operating temperature range (-25°C ~ 85°C versus -25°C ~ 70°C), providing broader environmental tolerance. Both parts maintain REACH compliance and are manufactured by the same supplier, ensuring consistent quality and reliability standards.

The primary functional difference is that MF1PLUS8031DA4/03 operates as an RFID Transponder while MF1P4230DA4/00J functions as an RFID Reader. This distinction must be evaluated against specific application requirements to confirm functional compatibility within the target system architecture.

Frequently Asked Questions (FAQ)

Q: Can MF1P4230DA4/00J directly replace MF1PLUS8031DA4/03 in existing designs?

A: Both parts share identical package designation (MOA4), supplier device package (PLLMC), mounting type (surface mount), and distribution format (Tape & Reel). Mechanical and electrical interface compatibility is established. However, the functional difference between transponder and reader operation requires application-level verification.

Q: What is the significance of the MOA4 package designation?

A: MOA4 designates a specific smart card module form factor and pinout configuration. Both the main part and substitute maintain this designation, ensuring footprint and pin alignment compatibility on PCB assemblies.

Q: Why is the operating temperature range different between these parts?

A: MF1P4230DA4/00J supports -25°C ~ 85°C operation, extending the upper temperature limit by 15°C compared to MF1PLUS8031DA4/03 (-25°C ~ 70°C). This provides additional thermal margin for applications operating in elevated ambient conditions.

Q: What does PLLMC supplier device package indicate?

A: PLLMC is the supplier-specific package designation that defines the physical form factor, pin configuration, and mechanical dimensions. Matching PLLMC designations between parts confirms compatibility at the assembly level.

Q: Are both parts compliant with current regulatory requirements?

A: Both parts maintain REACH Unaffected status. MF1PLUS8031DA4/03 is ROHS3 Compliant. Regulatory compliance documentation should be verified for specific application jurisdictions.
