Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 4MA074250Z4AACTGI8 is determined by strict alignment with the following electrical and mechanical parameters:

• Frequency: 74.25 MHz (exact match required)
• Output: LVDS (exact match required)
• Supply Voltage: 3.3V (exact match required)
• Function: Enable/Disable (exact match required)
• Frequency Stability: ±50ppm or better (equal or tighter tolerance acceptable)
• Operating Temperature: -40°C to 85°C (exact match required)
• Package: 6-SMD, No Lead (exact match required)
• Physical Dimensions: 5.00mm x 3.20mm (exact match required)
• Mounting Type: Surface Mount (exact match required)

All identified substitute parts meet these core electrical and mechanical compatibility criteria. Variations in current consumption, height, base resonator technology (MEMS vs. Crystal), and compliance certifications are noted but do not preclude functional substitution when electrical parameters align.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed are Active status components, providing long-term availability and supply chain stability compared to the Obsolete 4MA074250Z4AACTGI8. Selection among substitutes should be based on the following criteria:

Skyworks Solutions 511BAA74M2500BAGR and 510BBA74M2500BAG: Both offer significantly reduced current consumption (23mA maximum vs. 105mA typical for the original part) and improved moisture sensitivity rating (MSL 1 vs. MSL 3). The 510BBA74M2500BAG provides superior frequency stability at ±25ppm. Both are ROHS3 compliant and REACH unaffected. The 511BAA74M2500BAGR is supplied in Tape & Reel packaging, while the 510BBA74M2500BAG is supplied in Strip packaging.

CTS-Frequency Controls 653L7423I3T, 653V7423I3T, 654L7423I3T, and 654V7423I3T: All four CTS parts maintain the ±50ppm frequency stability specification and are ROHS3 compliant with REACH unaffected status. Current consumption ranges from 65-66mA maximum. The 654-series parts (654L7423I3T and 654V7423I3T) offer lower disable current (22mA) compared to the 653-series. All CTS parts feature MSL 1 moisture sensitivity rating.

Height considerations: The original part measures 0.90mm maximum seated height. All substitute parts exceed this dimension (1.28-1.40mm), requiring verification of available PCB clearance in the target application.

Frequently Asked Questions (FAQ)

Q: Can the 4MA074250Z4AACTGI8 be directly replaced with any of these substitute parts?

A: Yes, all listed parts are electrically and mechanically compatible based on matching frequency (74.25 MHz), output type (LVDS), supply voltage (3.3V), function (Enable/Disable), frequency stability (±50ppm or better), operating temperature range (-40°C to 85°C), and package configuration (6-SMD, No Lead, 5.00mm x 3.20mm). Physical height differences must be verified against PCB layout constraints.

Q: What is the primary difference between the Renesas MEMS-based original part and the crystal-based substitutes?

A: The original 4MA074250Z4AACTGI8 uses MEMS resonator technology, while all substitute parts employ crystal resonators. Both technologies deliver the required 74.25 MHz frequency and ±50ppm stability. Crystal-based substitutes generally offer lower current consumption and improved moisture sensitivity ratings (MSL 1 vs. MSL 3).

Q: Which substitute offers the best power efficiency?

A: The Skyworks Solutions parts (511BAA74M2500BAGR and 510BBA74M2500BAG) provide the lowest maximum current consumption at 23mA, compared to 65-66mA for CTS parts and 105mA for the original. The 510BBA74M2500BAG additionally offers ±25ppm frequency stability, exceeding the ±50ppm specification.

Q: Are all substitute parts RoHS and REACH compliant?

A: Yes, all substitute parts are ROHS3 compliant and REACH unaffected. The original part's compliance status is not specified in the provided data.

Q: What packaging options are available?

A: The Skyworks 511BAA74M2500BAGR is supplied in Tape & Reel (TR) packaging. The Skyworks 510BBA74M2500BAG is supplied in Strip packaging. All CTS parts (653L7423I3T, 653V7423I3T, 654L7423I3T, 654V7423I3T) are supplied in Tape & Reel (TR) packaging.

Q: Does the increased height of substitute parts affect PCB design?

A: Substitute parts range from 1.28mm to 1.40mm maximum seated height, compared to 0.90mm for the original part. PCB layout must accommodate this 0.38-0.50mm height increase. Verify clearance with surrounding components and any conformal coating or encapsulation processes.

Q: What is the moisture sensitivity implication of upgrading from MSL 3 to MSL 1?

A: MSL 1 (Unlimited) provides superior moisture protection compared to MSL 3 (168 Hours), reducing risk during storage, handling, and assembly processes. This represents an improvement in component robustness for manufacturing environments.
