Substitute Part Grouping Explanation

Substitution for the 4MA159375Z3BACTGI8 is determined by strict equivalence across the following critical parameters: frequency (159.375 MHz), output standard (LVPECL), supply voltage (2.5V), Enable/Disable function, package type (6-SMD, No Lead), and surface mount configuration. Substitute parts must maintain identical electrical interface specifications and physical footprint compatibility.

The substitute parts are grouped into two categories:

Direct Equivalents (CTS-Frequency Controls 653 Series): Parts 653E15933I2T and 653P15933I2T are crystal-based oscillators that meet all electrical and mechanical requirements of the original MEMS oscillator, with identical frequency, output, voltage, function, and package specifications.

Manufacturer-Recommended Upgrade (Renesas XPRESSO™ FXO-PC52 Series): Part XLP528159.375000X is the active-production successor from the original manufacturer, offering improved frequency stability and lower power consumption while maintaining package and electrical compatibility.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Pin-Compatible Substitution): The 653E15933I2T and 653P15933I2T from CTS-Frequency Controls provide direct electrical and mechanical equivalence to the 4MA159375Z3BACTGI8. Both parts are Active products with ROHS3 compliance and superior moisture sensitivity ratings (MSL 1 vs. MSL 3). Current consumption is reduced to 88mA maximum. These parts are suitable for applications where the original MEMS oscillator specifications are required and the slightly increased height (1.40mm vs. 0.90mm) is accommodated by PCB layout.

For Upgraded Performance (Manufacturer-Recommended): The XLP528159.375000X from Renesas Electronics is the active-production successor offering improved frequency stability (±20ppm vs. ±50ppm) and significantly lower power consumption (41mA vs. 100mA). This part maintains full electrical compatibility and ROHS3 compliance. The operating temperature range is narrower (-20°C ~ 70°C vs. -40°C ~ 85°C), and dimensions are marginally larger (5.15mm x 3.35mm vs. 5.00mm x 3.20mm). This option is recommended for new designs and applications where the temperature range and power budget are compatible.

Frequently Asked Questions (FAQ)

Q: Can the 653E15933I2T or 653P15933I2T be used as direct replacements for the 4MA159375Z3BACTGI8? A: Yes. Both CTS parts meet all electrical specifications (frequency, output type, supply voltage, function) and package requirements (6-SMD, No Lead, surface mount). The primary physical difference is increased seated height (1.40mm vs. 0.90mm), which must be verified against PCB clearance constraints.

Q: What is the difference between 653E15933I2T and 653P15933I2T? A: Both parts are electrically and mechanically identical. The difference is in packaging designation (E vs. P series designation from CTS-Frequency Controls). Both are available in Tape & Reel format and meet the same specifications.

Q: Why does the XLP528159.375000X have a narrower operating temperature range? A: The XLP528159.375000X is a crystal-based oscillator with different thermal characteristics than the original MEMS design. The -20°C ~ 70°C range is the specified operating window for this product. Applications requiring -40°C ~ 85°C operation should use the CTS 653 series equivalents.

Q: Is the XLP528159.375000X compatible with the original PCB layout? A: The XLP528159.375000X maintains the same 6-SMD, No Lead package and surface mount configuration. Dimensions are slightly larger (5.15mm x 3.35mm vs. 5.00mm x 3.20mm), requiring verification of PCB footprint and clearance. Height is identical to the CTS parts (1.40mm).

Q: What are the compliance and regulatory differences? A: The original 4MA159375Z3BACTGI8 does not specify RoHS or REACH status. All substitute parts (653E15933I2T, 653P15933I2T, XLP528159.375000X) are ROHS3 Compliant and REACH Unaffected, meeting current environmental regulations.

Q: Which substitute part should be selected for new designs? A: The XLP528159.375000X is recommended for new designs as the active-production part from the original manufacturer, offering superior frequency stability and lower power consumption. For applications requiring the full -40°C ~ 85°C temperature range, the CTS 653 series provides equivalent performance.
