Key Parameters

Substitute Part Grouping Explanation

Substitution of the LXMS21ACMF-183 is based on the following critical parameters:

• Identical manufacturer (Murata Electronics) and series (MAGICSTRAP®)
• Matching frequency range (865MHz ~ 928MHz)
• Equivalent standards compliance (ISO 18000-6 series, EPC)
• Compatible operating temperature range (-40°C ~ 85°C)
• ROHS3 compliance maintained

The primary difference between the main part and its substitute lies in packaging format and product status. The LXMS21ACMF-183 uses a Module package type, while the substitute employs a standardized 0805 (2012 Metric) surface mount package. Both maintain functional equivalence for RFID transponder applications within the specified frequency and standards framework.

Parameter Comparison

Engineering Selection Recommendations

The LXMS21ACMF-218 is the active equivalent for the obsolete LXMS21ACMF-183. Both components maintain identical frequency operation, standards compliance, and temperature specifications. The LXMS21ACMF-218 is recommended for new designs and ongoing production due to its active product status and confirmed availability. Both parts carry ROHS3 compliance and are suitable for applications requiring UHF RFID transponder functionality within the 865MHz to 928MHz band.

The transition from Module packaging to 0805 (2012 Metric) surface mount format requires PCB layout adjustment but does not affect electrical performance or standards compliance.

Frequently Asked Questions (FAQ)

Q: Can LXMS21ACMF-218 directly replace LXMS21ACMF-183 in existing designs?

A: Electrical and functional replacement is direct. Physical layout modification is required due to package format change from Module to 0805 (2012 Metric) surface mount.

Q: Are the frequency ranges identical between these parts?

A: Yes. Both components operate across 865MHz to 928MHz and comply with ISO 18000-6 series and EPC standards.

Q: What is the significance of the different ISO standards (ISO 18000-6 vs. ISO 18000-63)?

A: ISO 18000-63 is a specific subset of the ISO 18000-6 family. Both maintain compatibility within the EPC framework for UHF RFID applications.

Q: Does the moisture sensitivity level difference affect substitution?

A: The LXMS21ACMF-183 has MSL 1 (unlimited shelf life), while LXMS21ACMF-218 has MSL 2 (1 year). Storage and handling procedures must align with the stricter MSL 2 requirement for the substitute part.

Q: Are both parts RoHS compliant?

A: Yes. Both LXMS21ACMF-183 and LXMS21ACMF-218 are ROHS3 compliant.
