4MA250000Z3BACTGI Equivalent & Substitute Parts

Part Overview

The 4MA250000Z3BACTGI is a 250 MHz MEMS-based XO (Standard) oscillator manufactured by Renesas Electronics Corporation, featuring LVPECL output, 2.5V supply voltage, and Enable/Disable functionality in a 6-SMD, No Lead package. This part is classified as Obsolete, making identification of functionally equivalent alternatives essential for ongoing system support and new design implementations.

The primary reason for identifying substitute parts is the obsolete status of the original component. Active equivalent models ensure design continuity, supply chain reliability, and long-term product availability.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 4MA250000Z3BACTGI is determined by strict alignment of the following critical parameters:

• Frequency: 250 MHz (exact match required)
• Output Standard: LVPECL (exact match required)
• Supply Voltage: 2.5V (exact match required)
• Function: Enable/Disable capability (exact match required)
• Operating Temperature Range: -40°C ~ 85°C (exact match required)
• Package Configuration: 6-SMD, No Lead (exact match required)
• Mounting Type: Surface Mount (exact match required)

The substitute part 531EC250M000DG from Skyworks Solutions Inc. meets all these critical parameters. While the base resonator differs (Crystal vs. MEMS) and frequency stability specifications vary, the functional electrical and mechanical compatibility remains intact for direct substitution in applications requiring these specific parameters.

Engineering Selection Recommendations

The 531EC250M000DG from Skyworks Solutions Inc. is the qualified substitute for the obsolete 4MA250000Z3BACTGI. Selection of this alternative is supported by:

• Active product status ensuring long-term availability and supply chain continuity
• Identical electrical specifications for frequency, output type, supply voltage, and function
• Matching operating temperature range and package configuration
• Compliance with identical export classifications (EAR99) and tariff codes (HTSUS 8542.39.0001)
• Superior frequency stability (±7ppm vs. ±50ppm) providing enhanced performance margin
• Improved moisture sensitivity rating (MSL 1 vs. MSL 3) reducing handling and storage constraints

Physical dimension differences (package footprint and height) require PCB layout verification to ensure mechanical clearance compatibility in existing designs.

Frequently Asked Questions (FAQ)

Q: Can the 531EC250M000DG directly replace the 4MA250000Z3BACTGI without circuit modifications?

A: Electrical substitution is direct. The 531EC250M000DG provides identical frequency, output type, supply voltage, and enable/disable functionality. PCB layout verification is required due to different package dimensions (7.00mm x 5.00mm vs. 5.00mm x 3.20mm footprint and 1.80mm vs. 0.90mm height).

Q: What is the impact of the different base resonator technology (MEMS vs. Crystal)?

A: Both technologies deliver the required 250 MHz LVPECL output at 2.5V with Enable/Disable control. The Crystal-based 531EC250M000DG provides superior frequency stability (±7ppm vs. ±50ppm), which is advantageous for timing-critical applications.

Q: Are there any supply chain or availability concerns with the substitute part?

A: The 531EC250M000DG carries Active product status with 873 pieces in stock, ensuring immediate availability. The original 4MA250000Z3BACTGI is Obsolete with limited remaining inventory (780 pieces).

Q: How do the moisture sensitivity levels affect handling and storage?

A: The 531EC250M000DG has MSL 1 (Unlimited), requiring no special moisture control during storage or handling. The original part has MSL 3 (168 Hours), requiring controlled humidity storage and bake-out procedures before reflow soldering.

Q: Will the higher maximum supply current (121mA vs. 100mA) affect power supply design?

A: Power supply design should accommodate the 121mA maximum current specification of the 531EC250M000DG. This represents a 21mA increase and should be evaluated against existing power budget margins.
