SC-07-90J Common Mode Choke Equivalent & Substitute Parts

Part Overview

The SC-07-90J is a 9 mH common mode choke manufactured by KEMET, designed for power line filtering applications in two-line configurations. This through-hole component operates at 7A maximum current with a 50 mOhm DC resistance and is rated for 250V DC/AC operation across an operating temperature range of -40°C to 120°C. The part maintains Active product status and is ROHS3 compliant. Substitute parts may be required due to inventory constraints, application-specific parameter adjustments, or design optimization needs within the SC-J series.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SC-07-90J is determined by the following critical parameters: two-line configuration, through-hole mounting, 250V DC/AC voltage rating, -40°C to 120°C operating temperature range, ROHS3 compliance, and vertical 4-pin package format. All substitute parts listed maintain these core specifications.

The substitute parts are grouped into two categories based on current and inductance characteristics:

Category 1 - Same Current Rating (7A): SC-07-70J operates at 7A with 7 mH inductance at 1 kHz and 40 mOhm DCR, maintaining identical current capacity while varying inductance and measurement frequency.

Category 2 - Elevated Current Rating (8A): SC-08-30J, SC-08-20J, and SC-08-100JM all support 8A maximum current, accommodating higher current applications. These parts vary in inductance values (3 mH, 2 mH, and 13 mH respectively) measured at 100 kHz, with DCR values ranging from 50 mOhm to 54 mOhm.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts maintain Active product status and ROHS3 compliance, ensuring regulatory alignment with the original SC-07-90J specification. Selection between substitutes depends on application-specific inductance requirements and current capacity needs.

For applications requiring inductance values between 2 mH and 3 mH at 100 kHz with 8A capacity, SC-08-20J and SC-08-30J are suitable alternatives with identical footprint dimensions to the main part. SC-07-70J provides a same-current-rating option with lower DCR (40 mOhm) and reduced inductance (7 mH at 1 kHz). SC-08-100JM accommodates higher inductance requirements (13 mH at 100 kHz) with increased physical dimensions and 8A current capacity.

Frequently Asked Questions (FAQ)

Q: Can SC-07-70J replace SC-07-90J in all applications? SC-07-70J maintains the same 7A current rating and 250V voltage specification. The primary difference is inductance value (7 mH @ 1 kHz versus 9 mH @ 10 kHz) and lower DCR (40 mOhm versus 50 mOhm). Substitution is valid only when the application tolerates the reduced inductance value.

Q: What is the difference between the SC-07 and SC-08 series substitutes? SC-08 series parts support 8A maximum current compared to 7A in SC-07 series. SC-08 parts are suitable for applications requiring higher current capacity. All maintain identical voltage ratings and operating temperature ranges.

Q: Are all substitute parts identical in physical size? SC-08-30J, SC-08-20J, and SC-07-90J share identical dimensions (34.00 x 23.00 mm, 33.00 mm height). SC-07-70J is slightly larger (35.00 x 25.00 mm, 35.00 mm height). SC-08-100JM has the largest footprint (41.00 x 32.00 mm, 40.00 mm height). PCB layout compatibility must be verified before substitution.

Q: Do all parts meet the same compliance standards? All listed parts are ROHS3 compliant, REACH unaffected, and classified as EAR99 for export control purposes. Compliance status is identical across all substitutes.

Q: What inductance value should I select for my application? Inductance selection depends on your circuit's frequency response requirements and filtering specifications. SC-07-90J provides 9 mH at 10 kHz. Lower inductance values (2-3 mH) are available in SC-08 series at 100 kHz. Higher inductance (13 mH) is available in SC-08-100JM at 100 kHz. Verify frequency-dependent performance against your design requirements.
