Key Parameters

Substitute Part Grouping Explanation

Substitution for the 4MA050000Z4BACTGI8 is determined by strict alignment of the following critical parameters:

• Frequency: 50 MHz (exact match required)
• Output: LVDS (exact match required)
• Supply Voltage: 2.5V (exact match required)
• Function: Enable/Disable (exact match required)
• Package: 6-SMD, No Lead (exact match required)
• Operating Temperature: -40°C ~ 85°C (exact match required)
• Frequency Stability: ±50ppm (exact match required)

All substitute parts listed below meet these criteria. The primary distinction between substitute groups is the base resonator type (Crystal vs. MEMS) and product status (Active vs. Obsolete).

Parameter Comparison

Engineering Selection Recommendations

CTS-Frequency Controls 653 Series (653L5003I2T, 653V5003I2T): These crystal-based XO oscillators provide direct functional equivalence to the 4MA050000Z4BACTGI8 with Active product status. Both parts are ROHS3 compliant with MSL 1 rating, offering superior moisture handling compared to the original part. Current consumption is reduced to 65-66mA maximum. These parts are suitable for applications requiring standard XO performance with enhanced environmental compliance.

CTS-Frequency Controls 654 Series (654L5003I2T, 654V5003I2T): These crystal-based XO oscillators also provide direct functional equivalence with Active product status and ROHS3 compliance. The 654 series features a lower seated height of 1.30mm compared to the 653 series at 1.40mm, and includes a specified Current - Supply (Disable) parameter of 22mA. These parts are suitable for space-constrained applications or designs requiring defined disable-mode current specifications.

Renesas Electronics XLL52V050.000000I (VCXO Alternative): This manufacturer-recommended part is a VCXO (Voltage Controlled Crystal Oscillator) rather than a standard XO. While it maintains the same frequency, output type, supply voltage, and package, the VCXO type introduces frequency tuning capability via control voltage. This part is suitable only for applications requiring frequency adjustment capability. Current consumption is significantly lower at 34mA maximum. The physical dimensions are slightly larger (5.15mm x 3.35mm). This part is classified as a functional alternative rather than a direct substitute due to the oscillator type difference.

Frequently Asked Questions (FAQ)

Q: Can I directly replace the 4MA050000Z4BACTGI8 with any of the listed substitute parts?

A: The CTS-Frequency Controls 653 and 654 series parts (653L5003I2T, 653V5003I2T, 654L5003I2T, 654V5003I2T) are direct functional substitutes meeting all critical electrical and mechanical parameters. The Renesas XLL52V050.000000I is a VCXO alternative suitable only for applications requiring frequency tuning capability.

Q: What is the difference between the 653 and 654 series substitutes?

A: Both series are crystal-based XO oscillators with identical electrical performance. The primary differences are: 654 series has a lower seated height (1.30mm vs. 1.40mm) and includes a specified disable-mode current parameter (22mA). Select 654 series for space-constrained PCB layouts or designs requiring disable-mode current specifications.

Q: Why is the original part classified as Obsolete?

A: The 4MA050000Z4BACTGI8 is an older MEMS-based design. The listed substitutes represent current production alternatives with improved compliance ratings (ROHS3), better moisture sensitivity levels (MSL 1), and lower power consumption.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All CTS-Frequency Controls and Renesas substitute parts listed are ROHS3 compliant. The original 4MA050000Z4BACTGI8 does not specify RoHS compliance.

Q: What is the moisture sensitivity difference between the original and substitutes?

A: The original part has MSL 3 (168 hours maximum floor life). All substitute parts have MSL 1 (unlimited floor life), providing superior moisture handling and extended shelf life without baking requirements.

Q: Can I use the Renesas XLL52V050.000000I as a drop-in replacement?

A: The XLL52V050.000000I is physically compatible but functionally different as a VCXO. It introduces frequency tuning capability and requires control voltage input. Use only if your application requires frequency adjustment. Standard XO substitutes (653 or 654 series) are recommended for direct replacement.

Q: What are the current consumption differences?

A: The original part draws 100mA typical. CTS 653 and 654 series draw 65-66mA maximum. The Renesas VCXO draws 34mA maximum. Lower current consumption in substitutes reduces power dissipation and thermal load.

Q: Are the physical dimensions identical?

A: The CTS 653 and 654 series match the original dimensions (5.00mm x 3.20mm). The Renesas VCXO is slightly larger (5.15mm x 3.35mm). Verify PCB layout clearances if using the VCXO alternative.
