Key Parameters

Substitute Part Grouping Explanation

The SPD62R-563M qualifies as a substitute for the SCRH64B-560 based on the following critical parameters:

• Identical inductance value: 56 µH at 1 kHz test frequency
• Identical inductance tolerance: ±20%
• Current rating compatibility: 680 mA (exceeds 580 mA requirement)
• Shielded construction maintained
• Surface mount configuration preserved
• RoHS3 compliance maintained
• Operating temperature range: -55°C ~ 125°C (extends lower temperature capability)

The substitute part demonstrates electrical compatibility through matching inductance specifications and exceeding current handling capacity. Physical dimensions vary slightly between the two components; dimensional verification against PCB layout is required prior to implementation.

Parameter Comparison

Engineering Selection Recommendations

The SPD62R-563M is suitable as a direct substitute for the SCRH64B-560 based on the following factors:

• Both components maintain ROHS3 compliance and identical moisture sensitivity ratings, ensuring regulatory and environmental compatibility
• The substitute part is currently in active production status with substantial inventory availability (17,660 pcs), providing supply chain continuity
• Electrical parameters align within acceptable tolerances: matching inductance and tolerance specifications with superior current handling capacity
• Physical footprint differences require PCB layout verification; the substitute exhibits reduced height (3.00mm vs 5.20mm) and minimal length/width variation

Frequently Asked Questions (FAQ)

Q: Can the SPD62R-563M directly replace the SCRH64B-560 without circuit modifications?

A: Electrical substitution is valid based on matching inductance values and tolerances. Physical footprint verification is mandatory due to dimensional differences, particularly the reduced height of the substitute component.

Q: What is the impact of the higher DC resistance in the SPD62R-563M (850mOhm vs 560mOhm)?

A: The substitute exhibits 290mOhm additional resistance. Circuit performance impact depends on application-specific requirements; power dissipation calculations should be performed for current-critical applications.

Q: Are both components suitable for the same operating temperature range?

A: The SPD62R-563M extends the lower operating temperature limit to -55°C compared to the SCRH64B-560 at -40°C. Both maintain the upper limit of 125°C. Application requirements determine if extended low-temperature capability is necessary.

Q: What packaging considerations apply to the SPD62R-563M?

A: The substitute is supplied in Tape & Reel (TR) packaging, whereas the main part packaging format is not specified. Verify packaging compatibility with assembly equipment and procurement requirements.

Q: Why is the SCRH64B-560 obsolete and what does this mean for long-term availability?

A: Obsolete status indicates the part is no longer manufactured by Signal Transformer. The SPD62R-563M, with active production status and high inventory levels, provides a viable path for sustained component availability.
