Substitute Part Grouping Explanation

Substitution of the 4MA155520Z3BACUGI is determined by strict alignment of the following electrical and mechanical parameters:

• Frequency Match: 155.52 MHz (exact)
• Output Standard: LVPECL (required for signal compatibility)
• Supply Voltage: 2.5V (required for circuit integration)
• Enable/Disable Function: Present (required for system control)
• Frequency Stability: ±50ppm (required tolerance specification)
• Operating Temperature Range: -40°C ~ 85°C (required environmental specification)
• Package / Case: 6-SMD, No Lead (required for PCB footprint compatibility)
• Mounting Type: Surface Mount (required for assembly process)
• Physical Dimensions: 0.276" L x 0.197" W (7.00mm x 5.00mm) (required for board layout)

The P222-155.52M from Connor Winfield meets all mandatory electrical and mechanical parameters for direct substitution.

Parameter Comparison

Engineering Selection Recommendations

The P222-155.52M is a direct functional substitute for the obsolete 4MA155520Z3BACUGI. Both components share identical electrical specifications for frequency, output standard, supply voltage, enable/disable function, frequency stability, and operating temperature range. Both are packaged in 6-SMD, No Lead format with matching footprint dimensions.

The P222-155.52M offers the advantage of active product status, ensuring continued availability and manufacturing support. The substitute exhibits improved moisture sensitivity characteristics (MSL 1 versus MSL 3), lower maximum supply current (90mA versus 100mA), and reduced seated height (2.00mm versus 0.90mm). These differences are compatible with standard circuit design practices for 155.52 MHz LVPECL oscillator applications.

Both components carry identical export classification (EAR99) and tariff codes (8542.39.0001).

Frequently Asked Questions (FAQ)

Q: Can the P222-155.52M replace the 4MA155520Z3BACUGI in existing designs?

A: Yes. Both components meet identical electrical specifications for frequency (155.52 MHz), output type (LVPECL), supply voltage (2.5V), enable/disable function, frequency stability (±50ppm), and operating temperature range (-40°C ~ 85°C). Both use 6-SMD, No Lead packaging with matching footprint dimensions (7.00mm x 5.00mm).

Q: What is the difference between MEMS and Crystal base resonators in these parts?

A: The 4MA155520Z3BACUGI uses MEMS technology while the P222-155.52M uses a crystal resonator. Both deliver identical electrical performance at 155.52 MHz with ±50ppm stability. The choice between resonator technologies does not affect substitution compatibility when all electrical and mechanical parameters match.

Q: Are there any height considerations for PCB layout?

A: The P222-155.52M has a maximum seated height of 2.00mm compared to 0.90mm for the 4MA155520Z3BACUGI. Verify that your PCB layout and component clearance specifications accommodate the taller profile of the substitute part.

Q: What does MSL rating mean for these oscillators?

A: Moisture Sensitivity Level (MSL) indicates the component's sensitivity to moisture during storage and handling. The P222-155.52M carries MSL 1 (unlimited shelf life), while the 4MA155520Z3BACUGI carries MSL 3 (168-hour limit). The substitute part offers superior moisture tolerance characteristics.

Q: Is the lower supply current of the P222-155.52M significant?

A: The P222-155.52M draws a maximum of 90mA compared to 100mA for the 4MA155520Z3BACUGI. This 10mA reduction may provide minor power consumption benefits in battery-powered or thermally constrained applications, but both values are within typical design margins for 155.52 MHz LVPECL oscillator circuits.
