4MA085000Z3AACTGI Equivalent & Substitute Parts

Part Overview

The 4MA085000Z3AACTGI is a 85 MHz MEMS-based XO (Standard) oscillator manufactured by Renesas Electronics Corporation, featuring LVPECL output, 3.3V supply voltage, and Enable/Disable functionality in a 6-SMD, No Lead package. This part is classified as Obsolete, making identification of suitable substitute components essential for ongoing system support and new design implementations.

The primary reason for seeking alternative models is the discontinued status of this MEMS oscillator. Active substitute parts maintain functional and electrical compatibility while offering improved availability and extended product lifecycle support.

Substitute Part Grouping Explanation

Substitution eligibility for the 4MA085000Z3AACTGI is determined by strict alignment of the following critical parameters:

• Frequency: Exact match at 85.0000 MHz
• Output Configuration: LVPECL output type
• Supply Voltage: 3.3V operation
• Enable/Disable Function: Required control capability
• Package Format: 6-SMD, No Lead form factor
• Mounting Technology: Surface Mount compatibility

The XLP735085.000000X meets all substitution criteria as a manufacturer-recommended alternative. Both parts share identical frequency, output type, supply voltage, function, and package specifications, enabling direct functional replacement in existing designs.

Engineering Selection Recommendations

The XLP735085.000000X is the manufacturer-recommended substitute for the 4MA085000Z3AACTGI. Selection of this alternative is supported by:

• Active Product Status: The XLP735085.000000X maintains active manufacturing status, ensuring long-term availability and supply chain continuity.
• Regulatory Compliance: RoHS3 compliance and REACH Unaffected status provide enhanced environmental and regulatory alignment for new designs.
• Functional Equivalence: Identical frequency, output type, supply voltage, and control function enable direct replacement without circuit modification.
• Improved Moisture Handling: MSL 1 rating (Unlimited) versus MSL 3 (168 Hours) reduces moisture-related handling and storage constraints.

Physical dimension differences (footprint and height) require PCB layout verification to confirm mechanical compatibility in existing designs. The increased current draw (120mA versus 100mA typical) must be evaluated against power supply capacity.

Frequently Asked Questions (FAQ)

Q: Can the XLP735085.000000X be used as a direct drop-in replacement for the 4MA085000Z3AACTGI?

A: Electrical and functional compatibility is confirmed. Physical dimensions differ; PCB layout verification is required to confirm mechanical fit within existing designs.

Q: What are the key differences between these parts?

A: The primary differences are base resonator technology (MEMS versus Crystal), operating temperature range (-40°C to 85°C versus -20°C to 70°C), physical dimensions, and product lifecycle status (Obsolete versus Active).

Q: Does the XLP735085.000000X meet the same frequency stability specification?

A: Yes, both parts maintain ±50ppm frequency stability.

Q: Are there supply voltage or output type differences?

A: No. Both parts operate at 3.3V supply and provide LVPECL output with Enable/Disable functionality.

Q: What is the impact of the increased current specification?

A: The XLP735085.000000X specifies 120mA maximum supply current versus 100mA typical for the 4MA085000Z3AACTGI. Power supply capacity must be verified to accommodate this increase.

Q: How do the package dimensions affect substitution?

A: The XLP735085.000000X is larger (7.50mm x 5.20mm versus 5.00mm x 3.20mm) and taller (1.40mm versus 0.90mm). PCB layout and clearance verification is necessary before implementation.

Q: What is the significance of the MSL rating difference?

A: The XLP735085.000000X carries MSL 1 (Unlimited moisture exposure) versus MSL 3 (168 hours) for the 4MA085000Z3AACTGI, reducing moisture-related handling and storage requirements.
