Key Parameters

Substitute Part Grouping Explanation

Substitution of the SFSCE10M7WF04-R0 is determined by the following critical electrical and mechanical parameters:

Electrical Compatibility Criteria:

• Center frequency: 10.7 MHz (required match)
• Impedance: 470 Ohm (required match)
• Filter type: FM (required match)

Mechanical Compatibility Criteria:

• Mounting type: Surface Mount (required match)
• Pad configuration and footprint compatibility

Performance Considerations:

• Bandwidth tolerance (400 kHz nominal)
• Insertion loss characteristics
• Environmental compliance (RoHS3, REACH)

The SFECV10M7CQ0C01-R0 qualifies as a substitute based on matching center frequency, impedance, filter type, and surface mount configuration. Differences in bandwidth (500 kHz vs. 400 kHz), insertion loss (2 dB vs. 6 dB), package dimensions, and pad count reflect design evolution while maintaining core electrical functionality.

Parameter Comparison

Engineering Selection Recommendations

The SFECV10M7CQ0C01-R0 is the manufacturer-recommended substitute for the obsolete SFSCE10M7WF04-R0. Both components maintain ROHS3 compliance and are manufactured by Murata Electronics, ensuring regulatory consistency.

The substitute offers improved insertion loss performance (2 dB vs. 6 dB), which reduces signal attenuation in FM filter applications. The wider bandwidth (500 kHz vs. 400 kHz) provides broader frequency response characteristics suitable for modern FM receiver designs.

Critical consideration: The substitute employs a different package footprint (2706 with 3 pads vs. 1715 with 4 pads) and altered physical dimensions. PCB layout modifications are required for implementation. The increased height (1.70mm vs. 1.00mm) must be evaluated against available board space constraints.

The active product status of the SFECV10M7CQ0C01-R0 ensures long-term availability and supply chain stability compared to the obsolete original component.

Frequently Asked Questions (FAQ)

Q: Can the SFECV10M7CQ0C01-R0 directly replace the SFSCE10M7WF04-R0 without PCB modifications?

A: No. The substitute uses a different package footprint (2706 with 3 pads vs. 1715 with 4 pads) and altered dimensions. PCB layout redesign is required for proper implementation.

Q: What is the significance of the bandwidth difference (400 kHz vs. 500 kHz)?

A: The substitute's wider 500 kHz bandwidth provides broader frequency response. This affects filter selectivity and may require circuit tuning adjustments depending on application requirements.

Q: Does the improved insertion loss (2 dB vs. 6 dB) affect circuit design?

A: Yes. Lower insertion loss reduces signal attenuation, potentially improving receiver sensitivity. Amplifier gain stages may require adjustment to maintain system performance specifications.

Q: Are both components RoHS3 compliant?

A: Yes. Both the SFSCE10M7WF04-R0 and SFECV10M7CQ0C01-R0 meet ROHS3 compliance requirements.

Q: Why is the substitute component recommended despite package differences?

A: The SFECV10M7CQ0C01-R0 is the manufacturer-designated substitute, maintains identical electrical core specifications (10.7 MHz, 470 Ohm, FM filter type), and offers active product status with assured long-term availability.

Q: What is the pad count difference significance?

A: The original uses 4 pads; the substitute uses 3 pads. This reflects design optimization and requires corresponding footprint changes on the PCB.
