4MA050000Z4BACTGI Equivalent & Substitute Parts

Part Overview

The 4MA050000Z4BACTGI is a 50 MHz MEMS-based XO (Standard) oscillator manufactured by Renesas Electronics Corporation, designed for applications requiring LVDS output at 2.5V supply voltage with enable/disable functionality. This component is classified as obsolete, necessitating identification of functionally equivalent alternatives for ongoing system support and new designs. The part features surface mount packaging in a 6-SMD, No Lead configuration with a compact footprint of 5.00mm × 3.20mm and maximum height of 0.90mm.

Substitute Part Grouping Explanation

Substitution of the 4MA050000Z4BACTGI is determined by strict alignment of the following critical parameters:

• Frequency: 50 MHz (exact match required)
• Output Type: LVDS (exact match required)
• Supply Voltage: 2.5V (exact match required)
• Function: Enable/Disable capability (exact match required)
• Package / Case: 6-SMD, No Lead (exact match required)
• Mounting Type: Surface Mount (exact match required)
• Operating Temperature Range: -40°C ~ 85°C (exact match required)
• Manufacturer: Renesas Electronics Corporation (same manufacturer preferred for design continuity)

The XLL52V050.000000I meets all critical substitution criteria. While it employs a crystal-based resonator (VCXO) rather than MEMS technology, it maintains identical frequency, output type, supply voltage, function, package configuration, and operating temperature specifications. The VCXO architecture provides an additional feature (voltage-controlled frequency adjustment via APR of ±50ppm) not present in the standard XO design, making it functionally compatible for applications requiring fixed-frequency operation.

Engineering Selection Recommendations

The XLL52V050.000000I is the qualified substitute for the obsolete 4MA050000Z4BACTGI based on the following engineering criteria:

Product Status & Availability: The substitute part maintains active product status with documented inventory availability, ensuring long-term supply chain continuity compared to the obsolete main part.

Regulatory Compliance: The XLL52V050.000000I carries ROHS3 compliance and REACH unaffected status, meeting current environmental and regulatory requirements. Both parts share identical ECCN (EAR99) and HTSUS (8542.39.0001) classifications.

Electrical Compatibility: All critical electrical parameters align exactly: 50 MHz frequency, LVDS output, 2.5V supply, and enable/disable function. The substitute's lower maximum supply current (34mA versus 100mA typical) represents an operational advantage, reducing power consumption in the application.

Physical Compatibility: Both parts utilize identical 6-SMD, No Lead surface mount packaging. Dimensional differences are minimal (5.15mm × 3.35mm versus 5.00mm × 3.20mm footprint; 1.40mm versus 0.90mm height). PCB layout modifications may be required if height clearance is constrained; footprint verification is necessary for designs with tight component spacing.

Resonator Technology Transition: The shift from MEMS to crystal-based resonator technology does not impact fixed-frequency operation. The VCXO architecture's voltage-controlled capability remains unused in applications requiring standard XO functionality, presenting no compatibility risk.

Frequently Asked Questions (FAQ)

Q: Can the XLL52V050.000000I directly replace the 4MA050000Z4BACTGI without circuit modifications?

A: Yes, for applications requiring fixed 50 MHz LVDS output at 2.5V with enable/disable control. Both parts share identical electrical specifications for these functions. PCB layout verification is required due to minor dimensional differences, particularly the increased height (1.40mm versus 0.90mm).

Q: What is the significance of the VCXO (Voltage-Controlled) designation on the substitute part?

A: The XLL52V050.000000I incorporates voltage-controlled frequency adjustment capability (±50ppm APR). In applications using only fixed-frequency operation, this feature remains inactive and does not affect performance. The part functions identically to a standard XO when the control voltage is not applied.

Q: Are there any supply chain or lead time advantages to using the substitute part?

A: The XLL52V050.000000I maintains active product status with documented inventory availability, whereas the 4MA050000Z4BACTGI is classified as obsolete. This ensures reliable long-term sourcing and reduces procurement risk for new designs and ongoing production.

Q: How do the power consumption characteristics compare?

A: The substitute part operates at significantly lower maximum supply current (34mA versus 100mA typical), reducing overall system power consumption. This represents an operational improvement for battery-powered or power-constrained applications.

Q: What design considerations apply to the dimensional differences?

A: The substitute part is slightly larger in footprint (5.15mm × 3.35mm versus 5.00mm × 3.20mm) and significantly taller (1.40mm versus 0.90mm). Verify PCB layout clearance, particularly for applications with height constraints or dense component placement. Footprint compatibility must be confirmed before design release.

Q: Are regulatory certifications equivalent between the two parts?

A: Both parts share identical ECCN and HTSUS classifications. The substitute part carries explicit ROHS3 compliance and REACH unaffected status, meeting current environmental regulations. The main part's compliance status is not specified in available documentation.
