SCRH62B-470 Equivalent & Substitute Parts

Part Overview

The SCRH62B-470 is a 47 µH shielded inductor manufactured by Signal Transformer, rated for 750 mA continuous current with a maximum DC resistance of 690 mOhm. This component is classified as obsolete, making equivalent substitute parts necessary for new designs and ongoing production requirements. The part is surface-mounted in a nonstandard package measuring 6.50mm × 6.40mm with a maximum seated height of 3.20mm, and operates across the temperature range of -40°C to 125°C.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the SCRH62B-470 is determined by the following critical parameters: inductance value (47 µH), inductance tolerance (±20%), current rating capability, DC resistance, shielding configuration, surface-mount packaging, and operating temperature range. All substitute parts must maintain the 47 µH inductance specification and support the required current levels for the application. The three qualified substitutes are grouped based on their ability to meet these core electrical and mechanical requirements while maintaining ROHS3 compliance and MSL 1 rating.

Parameter Comparison

Engineering Selection Recommendations

CDR6D28MNNP-470NC (Sumida) is the primary substitute, offering the closest electrical performance to the SCRH62B-470 with 720 mA current rating, superior DC resistance of 458.8 mOhm, and shielded configuration. This part maintains ROHS3 compliance and active product status with high inventory availability.

MP2A-470-R (Eaton) provides an alternative for applications where unshielded construction is acceptable. It delivers 640 mA current rating with comparable DC resistance of 727 mOhm and maintains ROHS compliance. However, the operating temperature maximum of 85°C is lower than the original specification.

VLCF5020T-470MR40 (TDK) is suitable only for applications with current requirements not exceeding 400 mA. While it offers shielded construction and ROHS3 compliance, its 400 mA current rating and saturation current represent significant derating from the original 750 mA specification.

Frequently Asked Questions (FAQ)

Q: Can CDR6D28MNNP-470NC directly replace SCRH62B-470 in all applications? A: CDR6D28MNNP-470NC is compatible for applications requiring up to 720 mA continuous current. The inductance tolerance increases from ±20% to ±25%, and the maximum operating temperature decreases from 125°C to 105°C. Verify these parameters against your circuit requirements before substitution.

Q: What is the primary difference between the shielded and unshielded options? A: CDR6D28MNNP-470NC and VLCF5020T-470MR40 are shielded inductors, reducing electromagnetic interference. MP2A-470-R is unshielded. Shielding selection depends on circuit layout and EMI sensitivity requirements.

Q: Which substitute has the lowest DC resistance? A: CDR6D28MNNP-470NC offers the lowest DC resistance at 458.8 mOhm maximum, compared to 690 mOhm for the original part. Lower DCR reduces power dissipation and heat generation.

Q: Are all substitutes RoHS compliant? A: Yes. CDR6D28MNNP-470NC, MP2A-470-R, and VLCF5020T-470MR40 are all RoHS compliant with MSL 1 rating, suitable for lead-free soldering processes.

Q: What is the current rating limitation for VLCF5020T-470MR40? A: VLCF5020T-470MR40 is rated for 400 mA continuous current, significantly lower than the original 750 mA specification. This part is suitable only for low-current applications.

Q: How do the physical dimensions compare? A: VLCF5020T-470MR40 is the smallest at 5.00mm × 5.00mm with 2.00mm height. CDR6D28MNNP-470NC measures 6.50mm × 6.50mm with 3.00mm height. MP2A-470-R is 7.50mm × 5.20mm with 1.80mm height. Verify PCB layout compatibility before selection.
