Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 4MA074250Z3AACTGI8 are qualified based on the following electrical and mechanical parameters:

Critical Matching Parameters:

• Frequency: 74.25 MHz (exact match required)
• Output Type: LVPECL (exact match required)
• Supply Voltage: 3.3V (exact match required)
• Function: Enable/Disable (exact match required)
• Frequency Stability: ±50ppm (exact match required)
• Operating Temperature Range: -40°C to 85°C (exact match required)
• Package / Case: 6-SMD, No Lead (exact match required)
• Mounting Type: Surface Mount (exact match required)

Allowable Variations:

• Base Resonator: MEMS or Crystal (both acceptable)
• Current - Supply (Max): Variations permitted within system design limits
• Height - Seated (Max): Variations permitted within PCB layout constraints
• Moisture Sensitivity Level (MSL): Lower MSL values (1) are acceptable as they indicate better moisture resistance
• Product Status: Active status preferred over obsolete

All substitute parts listed maintain identical electrical performance characteristics and physical footprint compatibility with the original part.

Parameter Comparison

Engineering Selection Recommendations

For Direct Footprint Compatibility (5.00mm x 3.20mm):

The 511AAA74M2500BAGR (Skyworks Solutions) offers the lowest current consumption at 43mA maximum supply current and features MSL 1 rating with unlimited moisture exposure tolerance. This part is recommended for applications where power efficiency is a primary concern and space constraints require the original compact footprint.

The CTS-Frequency Controls 653 and 654 series parts (653E7423I3T, 653P7423I3T, 654E7423I3T, 654P7423I3T) provide active product status with ROHS3 compliance and REACH unaffected certification. The 654 series variants include specified disable-mode current consumption (22mA), beneficial for power management applications. All CTS parts maintain the original 5.00mm x 3.20mm footprint.

For Manufacturer Continuity:

The XLP735074.250000I (Renesas Electronics Corporation) is the manufacturer-recommended upgrade path. This part maintains Renesas design and support continuity with active product status, ROHS3 compliance, and REACH unaffected certification. The larger 7.50mm x 5.20mm footprint requires PCB layout modification but offers 120mA maximum supply current capacity for demanding applications.

Compliance Considerations:

All active substitute parts listed carry ROHS3 compliance and REACH unaffected status, suitable for regulated markets. The MSL 1 rating on all active substitutes provides superior moisture handling compared to the original MSL 3 specification.

Frequently Asked Questions (FAQ)

Q: Can I use any of these substitute parts as a direct replacement for the 4MA074250Z3AACTGI8?

A: The 511AAA74M2500BAGR, 653E7423I3T, 653P7423I3T, 654E7423I3T, and 654P7423I3T are direct footprint replacements with identical electrical specifications. The XLP735074.250000I requires PCB layout modification due to its larger 7.50mm x 5.20mm footprint versus the original 5.00mm x 3.20mm size.

Q: What is the difference between the CTS 653 and 654 series parts?

A: Both series maintain identical electrical performance and footprint. The 654 series (654E7423I3T, 654P7423I3T) provides specified disable-mode current consumption of 22mA, while the 653 series does not specify this parameter. Selection depends on whether disable-mode current monitoring is required for your application.

Q: Why does the Skyworks 511AAA74M2500BAGR have lower current consumption than other substitutes?

A: The 511AAA74M2500BAGR is specified at 43mA maximum supply current compared to 88mA for CTS parts and 100mA for the original. This reflects design optimization for power efficiency. Verify that your system power budget accommodates the selected part's current requirements.

Q: Is the XLP735074.250000I footprint change acceptable for my design?

A: The XLP735074.250000I uses a 7.50mm x 5.20mm footprint versus the original 5.00mm x 3.20mm. PCB layout modification is required. This part is recommended only when manufacturer continuity with Renesas is essential or when the larger footprint accommodates your design constraints.

Q: What does MSL 1 (Unlimited) mean compared to the original MSL 3 (168 Hours)?

A: MSL 1 indicates the component can be exposed to moisture indefinitely without baking requirements. MSL 3 requires baking after 168 hours of moisture exposure. All active substitute parts feature superior MSL 1 rating, reducing manufacturing process constraints.

Q: Are all substitute parts ROHS3 compliant?

A: The CTS parts (653 and 654 series) and the Renesas XLP735074.250000I are explicitly ROHS3 compliant. The Skyworks 511AAA74M2500BAGR does not specify RoHS status in the provided data. Verify RoHS compliance requirements with your procurement specifications.

Q: Can I mix different substitute parts in the same production run?

A: All listed substitutes meet identical electrical and mechanical specifications for the critical parameters. However, verify with your quality and supply chain procedures regarding part interchangeability within a single production lot.
