4MA133333Z3BACTGI8 Equivalent & Substitute Parts

Part Overview

The 4MA133333Z3BACTGI8 is a MEMS-based XO (Standard) oscillator manufactured by Renesas Electronics Corporation, operating at 133.333 MHz with LVPECL output and 2.5V supply voltage. This component is classified as Obsolete, making identification of functionally equivalent substitute parts essential for ongoing system support and new design implementations.

The primary reason for identifying substitutes is the discontinued status of this MEMS oscillator. Alternative parts must maintain the same frequency output, signal format, and core electrical characteristics while accommodating differences in supply voltage, temperature range, and physical dimensions.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 4MA133333Z3BACTGI8 is determined by the following critical parameters:

• Frequency Match: 133.333 MHz (exact match required)
• Output Format: LVPECL (signal compatibility requirement)
• Function: Enable/Disable capability (functional requirement)
• Package: 6-SMD, No Lead (mechanical compatibility)
• Frequency Stability: ±50ppm (performance specification)

The XLP735133.333000X qualifies as a substitute based on matching all critical electrical and functional parameters. Differences in supply voltage (3.3V vs. 2.5V), operating temperature range (-20°C ~ 70°C vs. -40°C ~ 85°C), and physical dimensions represent design trade-offs that must be evaluated within the context of the target application's power budget and thermal environment.

Parameter Comparison

Engineering Selection Recommendations

The XLP735133.333000X is an active, production-supported substitute for the obsolete 4MA133333Z3BACTGI8. Both components are manufactured by Renesas Electronics Corporation and share identical frequency, output format, and functional characteristics.

Selection of the XLP735133.333000X requires evaluation of the following design considerations:

• Supply Voltage: The substitute operates at 3.3V instead of 2.5V. Power supply architecture must accommodate this higher voltage requirement.
• Operating Temperature Range: The substitute supports -20°C ~ 70°C versus the original -40°C ~ 85°C. Applications requiring extended low-temperature operation or high-temperature reliability must assess compatibility.
• Physical Dimensions: The substitute is larger (7.50mm x 5.20mm vs. 5.00mm x 3.20mm) and taller (1.40mm vs. 0.90mm). PCB layout and mechanical clearance must be verified.
• Compliance Status: The substitute carries ROHS3 and REACH certifications, providing regulatory compliance advantages for new designs and long-term supply chain stability.
• Moisture Sensitivity: The substitute has MSL 1 (Unlimited) versus MSL 3 (168 Hours), reducing handling and storage constraints.

Frequently Asked Questions (FAQ)

Q: Can the XLP735133.333000X be used as a direct pin-for-pin replacement?

A: Both parts use the 6-SMD, No Lead package format. However, the substitute is physically larger. PCB layout modifications may be required to accommodate the increased footprint dimensions (7.50mm x 5.20mm vs. 5.00mm x 3.20mm).

Q: What is the impact of the 3.3V supply voltage requirement?

A: The substitute requires 3.3V instead of 2.5V. Power supply circuits must be designed or modified to provide 3.3V at the oscillator input. This is a mandatory design change and cannot be overlooked.

Q: Are there temperature range limitations with the substitute?

A: The substitute operates from -20°C ~ 70°C, compared to the original -40°C ~ 85°C. Applications requiring operation below -20°C or above 70°C are outside the substitute's rated range and require alternative solutions.

Q: What are the advantages of using the XLP735133.333000X?

A: The substitute is an active product with ongoing manufacturer support, carries ROHS3 and REACH compliance certifications, has improved moisture sensitivity (MSL 1 vs. MSL 3), and provides better long-term supply chain availability.

Q: How do the frequency stability specifications compare?

A: Both parts specify ±50ppm frequency stability, ensuring equivalent timing accuracy for applications requiring this oscillator frequency.

Q: What is the difference between MEMS and Crystal resonator technology in these parts?

A: The original part uses MEMS (Micro-Electro-Mechanical Systems) technology, while the substitute uses a Crystal resonator. Both technologies deliver the same 133.333 MHz output and ±50ppm stability. The choice between technologies is transparent to the system design when electrical specifications are matched.
