Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SCRH62-470 is determined by the following critical parameters:

Primary Matching Criteria:

• Inductance value: 47 µH (±20% tolerance acceptable)
• Shielding requirement: Shielded configuration mandatory
• Mounting technology: Surface mount only
• Package classification: Nonstandard

Secondary Compatibility Factors:

• Current rating must meet or exceed application requirements
• DC resistance within acceptable operating margins
• Operating temperature range must encompass application environment
• RoHS3 compliance and MSL rating for manufacturing process compatibility

The VLCF5020T-470MR40 qualifies as a substitute based on matching inductance, shielding, surface mount configuration, and compliance certifications. Current rating differences require application-level verification.

Parameter Comparison

Engineering Selection Recommendations

Both the SCRH62-470 and VLCF5020T-470MR40 maintain Active product status with ROHS3 compliance and MSL Level 1 ratings, ensuring manufacturing process compatibility and long-term availability. The primary differentiation factor is current rating capacity: the SCRH62-470 supports 750 mA continuous operation, while the VLCF5020T-470MR40 is rated for 400 mA. Selection between these parts must be based on circuit current requirements. The VLCF5020T-470MR40 offers reduced physical footprint (5.00mm x 5.00mm versus 7.10mm x 6.50mm) and lower profile height (2.00mm versus 3.00mm), providing layout advantages in space-constrained applications where current demands do not exceed 400 mA. Operating temperature range differs by 20°C maximum; the SCRH62-470 extends to 125°C while the VLCF5020T-470MR40 operates to 105°C.

Frequently Asked Questions (FAQ)

Q: Can VLCF5020T-470MR40 replace SCRH62-470 in all applications?

A: Substitution is valid only when circuit current requirements do not exceed 400 mA. The VLCF5020T-470MR40 saturation current is 400mA compared to 500mA for the SCRH62-470. Applications requiring sustained current above 400 mA must use the SCRH62-470.

Q: What is the impact of DC resistance difference between these parts?

A: The VLCF5020T-470MR40 exhibits 748mOhm maximum DCR versus 690mOhm for the SCRH62-470, representing a 58mOhm increase. This affects power dissipation and thermal performance; calculate I²R losses for your specific current to determine acceptability.

Q: Are physical dimensions interchangeable?

A: No. The VLCF5020T-470MR40 is significantly smaller (5.00mm x 5.00mm x 2.00mm) compared to the SCRH62-470 (7.10mm x 6.50mm x 3.00mm). PCB layout and component placement must be re-evaluated. The smaller footprint may require design modifications to accommodate.

Q: Do both parts meet the same compliance requirements?

A: Yes. Both components are ROHS3 compliant, REACH unaffected, and classified as MSL Level 1 (Unlimited moisture sensitivity). Manufacturing process compatibility is equivalent.

Q: What is the operating temperature consideration?

A: The SCRH62-470 operates across -40°C to 125°C, while the VLCF5020T-470MR40 operates -40°C to 105°C. Applications requiring operation above 105°C must use the SCRH62-470.
