Substitute Part Grouping Explanation

Substitution of the 7W-48.000MBA-T is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Frequency: 48 MHz
• Output Type: CMOS
• Supply Voltage: 3.3V
• Function: Enable/Disable capability
• Frequency Stability: ±25ppm
• Operating Temperature Range: -10°C ~ 70°C
• Package Type: 4-SMD, No Lead
• Physical Dimensions: 7.00mm x 5.00mm
• Mounting Type: Surface Mount

The substitute part SXO75C3C171-48.000M from Suntsu Electronics, Inc. meets all mandatory matching parameters and is classified as Active product status, providing supply chain continuity for the obsolete 7W-48.000MBA-T.

Engineering Selection Recommendations

SXO75C3C171-48.000M is the direct substitute for the obsolete 7W-48.000MBA-T based on the following engineering criteria:

1. Functional Equivalence: All critical electrical parameters match exactly, including frequency, output type, supply voltage, enable/disable function, frequency stability, and operating temperature range.

2. Package Compatibility: Both parts use identical 4-SMD, no-lead surface mount packages with matching footprint dimensions of 7.00mm x 5.00mm, ensuring PCB layout compatibility without redesign.

3. Product Status: The SXO75C3C171-48.000M is classified as Active, providing reliable long-term supply availability compared to the Obsolete status of the 7W-48.000MBA-T.

4. Regulatory Compliance: Both parts meet RoHS requirements. The substitute carries ROHS3 compliance, meeting current environmental standards.

5. Current Rating Consideration: The substitute part is rated for 25mA maximum supply current versus 20mA for the original part. This higher rating provides design margin and does not create compatibility issues in applications designed for the original 20mA specification.

6. Physical Height Variance: The substitute part has a maximum seated height of 1.60mm compared to 1.42mm for the original. This 0.18mm difference must be verified against PCB clearance constraints in height-restricted applications.

Frequently Asked Questions (FAQ)

Q: Can the SXO75C3C171-48.000M be used as a direct replacement for the 7W-48.000MBA-T without PCB modifications?

A: Yes, for most applications. Both parts share identical footprint dimensions (7.00mm x 5.00mm) and 4-SMD, no-lead package type. However, verify that the additional 0.18mm height (1.60mm vs. 1.42mm) does not violate clearance requirements in your specific PCB assembly.

Q: Are there any electrical performance differences between these parts?

A: No. Both parts deliver identical electrical specifications: 48 MHz frequency, CMOS output, 3.3V supply, enable/disable function, ±25ppm frequency stability, and -10°C to 70°C operating range. The substitute's higher 25mA current rating provides additional design margin.

Q: What is the significance of the product status change from Obsolete to Active?

A: The Active status of the SXO75C3C171-48.000M ensures ongoing manufacturing support, consistent supply availability, and continued compliance with current regulatory standards. This eliminates supply chain risk associated with obsolete components.

Q: Does the packaging difference (Cut Tape vs. Bulk) affect component functionality?

A: No. Packaging format (Cut Tape for the original, Bulk for the substitute) affects only logistics and handling. Electrical and mechanical specifications remain identical. Confirm packaging availability aligns with your procurement and assembly requirements.

Q: Are both parts RoHS compliant?

A: Yes. The 7W-48.000MBA-T is RoHS Compliant, and the SXO75C3C171-48.000M is ROHS3 Compliant. Both meet environmental regulations for hazardous substance restrictions.
