SCRH62-150 Equivalent & Substitute Parts

Part Overview

The SCRH62-150 is a 15 µH shielded surface mount inductor manufactured by Signal Transformer, rated for 1.17 A continuous current with a maximum DC resistance of 230mOhm. This component is designed for applications requiring fixed inductance in compact form factors with electromagnetic shielding. The part is Active status and ROHS3 compliant, suitable for industrial and commercial electronic assemblies operating across the -40°C to 125°C temperature range. Substitute parts are identified when equivalent electrical performance and mechanical compatibility can be maintained within specified parameter tolerances.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SCRH62-150 is determined by the following critical parameters:

Inductance Value: Must be 15 µH with ±20% tolerance to maintain circuit performance.

Current Rating: Substitute parts must support minimum 1.17 A continuous current without exceeding saturation limits.

DC Resistance: Maximum allowable DCR is 230mOhm to prevent excessive power dissipation and thermal effects.

Shielding: Electromagnetic shielding is required to maintain EMI performance in the original application.

Mounting Type: Surface mount configuration is mandatory for PCB compatibility.

Environmental Compliance: ROHS3 compliance and MSL rating of 1 are required for manufacturing and storage compatibility.

The VLCF5020T-150MR71 from TDK Corporation qualifies as a substitute based on matching inductance value, shielding type, surface mount configuration, and compliance certifications. However, the current rating differential and operating temperature range variance require application-level verification.

Parameter Comparison

Engineering Selection Recommendations

SCRH62-150 (Primary Selection): Recommended for applications requiring the full 1.17 A current rating and extended operating temperature range to 125°C. Active product status with established supply chain (807 pcs in stock). ROHS3 and REACH compliance confirmed.

VLCF5020T-150MR71 (Substitute Selection): Applicable for circuits where current demand does not exceed 710 mA and operating temperature remains below 105°C. Offers reduced package footprint (5.00 x 5.00 mm vs. 7.10 x 6.50 mm) and lower profile (2.00 mm vs. 3.00 mm). Active product status with higher inventory availability (1810 pcs in stock). ROHS3 and REACH compliance confirmed. Ferrite drum core construction provides alternative magnetic characteristics.

Selection between these parts must account for actual circuit current requirements and thermal operating conditions. The substitute part's lower current rating and reduced temperature ceiling represent the primary design constraints.

Frequently Asked Questions (FAQ)

Q: Can VLCF5020T-150MR71 replace SCRH62-150 in all applications?

A: No. The substitute part has a maximum current rating of 710 mA compared to the main part's 1.17 A rating. Substitution is valid only when circuit current demand does not exceed 710 mA. Additionally, the operating temperature range is limited to -40 to 105°C versus -40 to 125°C for the main part.

Q: What are the physical compatibility differences?

A: The VLCF5020T-150MR71 has a smaller footprint (5.00 x 5.00 mm versus 7.10 x 6.50 mm) and lower height (2.00 mm versus 3.00 mm). Both are surface mount components with identical inductance values and shielding characteristics. PCB layout modifications may be required due to dimensional differences.

Q: Are both parts compliant with environmental regulations?

A: Yes. Both SCRH62-150 and VLCF5020T-150MR71 are ROHS3 compliant and REACH unaffected. Both carry MSL rating 1 (unlimited moisture sensitivity level), allowing standard storage and handling procedures.

Q: What is the significance of the DC resistance difference?

A: The VLCF5020T-150MR71 has a maximum DCR of 256 mOhm compared to 230 mOhm for the SCRH62-150. This 26 mOhm difference results in approximately 11% higher resistive losses at rated current. For low-power applications, this difference is negligible; for high-efficiency designs, thermal impact should be calculated.

Q: How do the core materials affect performance?

A: The SCRH62-150 core material is not specified in available data. The VLCF5020T-150MR71 uses a ferrite drum core with wirewound construction. Both maintain 15 µH inductance at 100 kHz test frequency with ±20% tolerance. Core material differences may affect frequency response characteristics outside the specified test frequency.

Q: What inventory considerations apply?

A: SCRH62-150 has 807 units in stock; VLCF5020T-150MR71 has 1810 units available. For high-volume production, the substitute part offers greater supply availability. For single-unit or low-volume requirements, both options are immediately available.
