Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the FMA253.A.LF.001 is determined by the following critical parameters:

Frequency Coverage Compatibility: The substitute must support the primary navigation bands required by the application. The FMA253.A.LF.001 covers GPS (1.575GHz), GLONASS (1.602GHz), Galileo (1.575GHz), and Beidou (1.561GHz) across 13 bands. Substitute parts must maintain coverage of these core navigation frequencies.

Connector Type: The SMA Male termination is a standard interface requirement. Substitute parts must use identical SMA Male connectors to ensure mechanical and electrical compatibility with existing RF pathways.

Mounting Configuration: The surface mount adhesive mounting type defines the physical integration method. Substitute parts must support equivalent adhesive or surface mount attachment to maintain form factor compatibility.

Electrical Performance: VSWR and Return Loss specifications define impedance matching characteristics. Substitute parts must meet or exceed the specified VSWR (2, 3) and Return Loss (-6dB, -10dB) values to ensure signal integrity.

Physical Envelope: The maximum height of 0.551" (14.00mm) constrains the available substitute options. Substitute parts must not exceed this dimension to fit within existing mechanical assemblies.

Integrated Features: The presence of integrated LNA (Low Noise Amplifier) and Filter components are functional requirements. Substitute parts must include equivalent signal conditioning features.

The MA252.A.LB.001 qualifies as a substitute based on shared frequency band support for navigation applications, SMA Male termination, surface mount capability, equivalent VSWR/Return Loss performance, matching physical height, and integrated LNA/Filter features.

Engineering Selection Recommendations

Product Status Consideration: The FMA253.A.LF.001 is obsolete, while the MA252.A.LB.001 maintains active product status. Active status ensures continued manufacturer support, availability of technical documentation, and potential design improvements.

Compliance Alignment: Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory compatibility across manufacturing jurisdictions. MSL rating of 1 (Unlimited) for both parts indicates equivalent moisture handling requirements.

Frequency Band Reduction: The MA252.A.LB.001 operates across 5 bands compared to 13 bands in the FMA253.A.LF.001. Applications requiring Galileo navigation support should verify that the reduced band count does not impact system performance, as the MA252.A.LB.001 does not explicitly list Galileo coverage.

Mounting Type Difference: The FMA253.A.LF.001 specifies surface mount, while the MA252.A.LB.001 uses adhesive mounting. Physical integration methods differ; adhesive mounting may require design modification to existing PCB attachment points.

Electrical Performance Equivalence: Both parts maintain identical VSWR (2, 3) and Return Loss (-6dB, -10dB) specifications, ensuring equivalent impedance matching and signal integrity characteristics.

Frequently Asked Questions (FAQ)

Q: Can the MA252.A.LB.001 directly replace the FMA253.A.LF.001 in existing designs?

A: Direct replacement requires verification of two factors: (1) Frequency band requirements—the MA252.A.LB.001 supports 5 bands versus 13 in the FMA253.A.LF.001, and does not list Galileo coverage; (2) Mounting method—the MA252.A.LB.001 uses adhesive mounting rather than surface mount, potentially requiring PCB design modification.

Q: What is the significance of the reduced band count in the MA252.A.LB.001?

A: The MA252.A.LB.001 covers GPS, GLONASS, Beidou, and LTE bands. Applications requiring Galileo navigation must confirm system compatibility, as Galileo support is not specified for this substitute part.

Q: Are the electrical performance characteristics equivalent between these parts?

A: Yes. Both parts maintain identical VSWR (2, 3) and Return Loss (-6dB, -10dB) specifications, ensuring equivalent impedance matching and signal conditioning performance.

Q: What are the packaging and inventory considerations?

A: The FMA253.A.LF.001 has 945 pieces in stock (obsolete status), while the MA252.A.LB.001 has 873 pieces available (active status). For new designs, the active status of MA252.A.LB.001 provides longer-term supply assurance.

Q: Do both parts meet the same regulatory and compliance standards?

A: Yes. Both parts are ROHS3 compliant, REACH unaffected, and carry MSL rating of 1 (Unlimited), ensuring equivalent regulatory compliance and moisture sensitivity handling.
