SCRH62B-150 Equivalent & Substitute Parts

Part Overview

The SCRH62B-150 is a 15 µH shielded inductor manufactured by Signal Transformer, rated for 1.17 A continuous current with a maximum DC resistance of 230 mOhm. This component is classified as obsolete, making identification of suitable substitute parts essential for ongoing design support and production continuity. Equivalent parts must maintain the same inductance value, shielding characteristics, and surface mount compatibility while meeting or exceeding the electrical performance requirements of the original specification.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SCRH62B-150 must satisfy the following mandatory electrical and mechanical criteria:

• Inductance value of 15 µH at 100 kHz test frequency
• Shielded construction to maintain electromagnetic isolation
• Surface mount package configuration
• Current rating sufficient to support 1.17 A continuous operation
• DC resistance within acceptable limits for the application
• Operating temperature range compatible with -40°C to 125°C specification
• ROHS3 compliance and MSL 1 rating

Two active substitute parts meet these requirements: the CDR6D28MNNP-150NC from Sumida America Components Inc. and the VLCF5020T-150MR71 from TDK Corporation. Both parts maintain the 15 µH inductance specification and shielded construction while offering improved current handling or reduced DC resistance compared to the obsolete original.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts are manufactured by active suppliers with current production status, ensuring long-term availability and supply chain stability compared to the obsolete SCRH62B-150.

The CDR6D28MNNP-150NC offers superior current handling capability at 1.4 A continuous rating with reduced DC resistance of 135 mOhm maximum, providing improved thermal performance and lower power dissipation. This part is suitable for applications requiring maximum current capacity within the 15 µH inductance specification.

The VLCF5020T-150MR71 from TDK Corporation features a compact drum core wirewound construction with a smaller physical footprint (5.00 mm × 5.00 mm × 2.00 mm height). This part is appropriate for space-constrained applications where the 710 mA current rating is sufficient. The ±20% inductance tolerance matches the original specification exactly.

Both substitute parts maintain ROHS3 compliance and MSL 1 rating, ensuring compatibility with standard manufacturing and storage requirements. The operating temperature range of both substitutes extends to 105°C, which is lower than the original 125°C maximum but remains suitable for most industrial and commercial applications.

Frequently Asked Questions (FAQ)

Q: Can the CDR6D28MNNP-150NC directly replace the SCRH62B-150 in all applications?

A: The CDR6D28MNNP-150NC maintains the same 15 µH inductance and shielded construction. The higher current rating of 1.4 A and lower DC resistance of 135 mOhm provide improved performance. The inductance tolerance increases from ±20% to ±25%, and the maximum operating temperature decreases from 125°C to 105°C. Verify that your application does not require operation above 105°C.

Q: What are the physical size differences between the substitute parts?

A: The SCRH62B-150 measures 6.50 mm × 6.40 mm with a height of 3.20 mm. The CDR6D28MNNP-150NC measures 6.50 mm × 6.50 mm with a height of 3.00 mm. The VLCF5020T-150MR71 is significantly smaller at 5.00 mm × 5.00 mm with a height of 2.00 mm. Confirm PCB layout compatibility before selection.

Q: Is the VLCF5020T-150MR71 suitable for high-current applications?

A: The VLCF5020T-150MR71 is rated for 710 mA continuous current, which is lower than the original SCRH62B-150 specification of 1.17 A. This part is suitable only for applications where the current requirement does not exceed 710 mA.

Q: Do both substitute parts meet the same compliance standards as the original?

A: Both substitute parts are ROHS3 compliant with MSL 1 rating, matching the original SCRH62B-150 specifications. Both are classified as REACH Unaffected and carry ECCN EAR99 designation.

Q: What is the impact of inductance tolerance differences?

A: The SCRH62B-150 and VLCF5020T-150MR71 both specify ±20% tolerance. The CDR6D28MNNP-150NC specifies ±25% tolerance. For applications with tight inductance requirements, the ±20% tolerance parts provide better consistency.
