SCRH62B-220 Equivalent & Substitute Parts

Part Overview

The SCRH62B-220 is a 22 µH shielded surface mount inductor manufactured by Signal Transformer, rated for 990 mA continuous current with a maximum DC resistance of 340 mOhm. This component is classified as obsolete, making equivalent substitutes necessary for new designs and ongoing production requirements. The part operates across the temperature range of -40°C to 125°C and is ROHS3 compliant with unlimited moisture sensitivity rating.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the SCRH62B-220 is determined by the following critical parameters: inductance value (22 µH), current rating capability, DC resistance characteristics, shielding configuration, surface mount compatibility, and operating temperature range. All substitute parts must maintain the 22 µH inductance specification and support minimum current ratings at or above 990 mA. The shielding requirement and temperature operating range are primary differentiators among available alternatives.

Three active substitute parts are identified:

CDR6D28MNNP-220NC (Sumida): Shielded inductor with higher current rating (1.1 A) and lower DCR (198.8 mOhm), suitable for applications requiring improved thermal performance.

CDRH5D28RH125NP-220MC (Sumida): Shielded inductor with current rating of 900 mA and DCR of 266 mOhm, matching the original temperature range of -40°C to 125°C.

MP2A-220-R (Eaton): Unshielded drum core inductor with 980 mA rating and 311 mOhm DCR, offering a lower profile alternative with different core material (Molybdenum Permalloy).

Engineering Selection Recommendations

CDRH5D28RH125NP-220MC is the primary substitute for direct replacement. This part maintains shielded configuration, matches the ±20% inductance tolerance, supports the required 900 mA minimum current rating, and preserves the full -40°C to 125°C operating temperature range. Product status is active with ROHS3 compliance and unlimited moisture sensitivity rating, ensuring long-term availability and regulatory alignment.

CDR6D28MNNP-220NC is suitable for applications where improved thermal performance is beneficial. The lower DCR (198.8 mOhm versus 340 mOhm) reduces power dissipation, and the higher saturation current (1.65 A) provides additional design margin. The reduced operating temperature upper limit (-40°C to 105°C) must be evaluated against application requirements.

MP2A-220-R is applicable only when shielding is not a circuit requirement. The unshielded configuration and lower profile (1.80 mm height) may offer space advantages in specific layouts. The reduced operating temperature range (-40°C to 85°C) and different core material (Molybdenum Permalloy versus ferrite) require circuit validation.

Frequently Asked Questions (FAQ)

Q: Can CDRH5D28RH125NP-220MC directly replace SCRH62B-220 in existing designs?

A: Yes. Both parts share 22 µH inductance at ±20% tolerance, support minimum 900 mA current rating, maintain shielded configuration, and operate across -40°C to 125°C. Physical dimensions differ slightly (6.00mm x 5.90mm versus 6.50mm x 6.40mm), requiring PCB layout verification.

Q: What is the primary advantage of CDR6D28MNNP-220NC?

A: The lower DC resistance (198.8 mOhm versus 340 mOhm) reduces resistive losses and heat generation. Higher saturation current (1.65 A) provides additional design margin for transient current conditions. The -40°C to 105°C temperature range is suitable for most industrial applications.

Q: When should MP2A-220-R be selected?

A: This unshielded alternative is appropriate for applications where electromagnetic shielding is not required and space constraints favor the lower profile (1.80 mm height). Circuit validation is necessary to confirm unshielded operation does not introduce EMI issues. The -40°C to 85°C operating range limits use in high-temperature environments.

Q: Are all substitutes ROHS3 compliant?

A: CDR6D28MNNP-220NC and CDRH5D28RH125NP-220MC are ROHS3 compliant. MP2A-220-R is RoHS compliant. Both certifications meet current regulatory requirements.

Q: What packaging options are available?

A: CDR6D28MNNP-220NC and MP2A-220-R are supplied in Tape & Reel (TR). CDRH5D28RH125NP-220MC is available in Cut Tape (CT) and Digi-Reel® formats, providing flexibility for different procurement and assembly workflows.
