SC22-05-70J Common Mode Choke Equivalent & Substitute Parts

Part Overview

The SC22-05-70J is a 7 mH common mode choke manufactured by KEMET, designed for two-line power line filtering applications. This through-hole component operates at 5A maximum current with 60 mOhm DC resistance and is rated for 250V DC/AC operation across an operating temperature range of -40°C to 120°C. The part is Active status and ROHS3 compliant. Substitute parts are identified when equivalent electrical performance can be achieved within the allowed parameter tolerances for the SC-J and SCR series common mode chokes.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SC22-05-70J are identified based on the following allowed parameters:

• Number of Lines: Must remain 2-line configuration
• Mounting Type: Must remain Through Hole
• Package / Case: Must remain Vertical, 4 PC Pin
• Voltage Rating: Must maintain 250V DC/AC minimum
• Filter Type: Must remain Power Line
• RoHS Status: Must maintain ROHS3 Compliance
• Product Status: Must be Active

Substitution is permitted when the above parameters are maintained. Variations in inductance value, current rating, DC resistance, and operating temperature range are allowed within the SC-J and SCR series product families, provided the substitute part meets or exceeds the electrical requirements of the application.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts maintain Active product status and ROHS3 compliance. Selection among substitute parts depends on specific application requirements for inductance value and current capacity.

SC22-05-30J and SC22-05-70J share identical physical dimensions (28.00 x 18.50 x 29.00 mm), enabling direct mechanical interchange in space-constrained applications. SC-06-35J and SC-06-60J feature larger dimensions (34.00 x 23.00/25.00 x 33.00 mm) and support higher current ratings (6A).

SCR22-050-0R9A090J operates within a narrower temperature range (25°C to 120°C) compared to the SC-J series (-40°C to 120°C). This restriction applies only when the application requires operation below 25°C.

Frequently Asked Questions (FAQ)

Q: Can SC-05-20J replace SC22-05-70J in all applications?

A: SC-05-20J is a valid substitute based on core parameters (2-line, through-hole, 250V, ROHS3, Active status). However, it provides 2 mH inductance at 100 kHz versus 7 mH at 10 kHz in the original part. Substitution is appropriate only when the application can function with lower inductance values.

Q: What is the difference between SC-J and SCR series parts?

A: Both series maintain identical electrical specifications and compliance certifications. SCR22-050-0R9A090J operates within a restricted temperature range (25°C to 120°C) compared to SC-J series parts (-40°C to 120°C). Select SCR series only when the application does not require sub-25°C operation.

Q: Are SC-06-35J and SC-06-60J physically interchangeable with SC22-05-70J?

A: SC-06-35J and SC-06-60J have larger physical dimensions (34.00 x 23.00/25.00 x 33.00 mm) compared to SC22-05-70J (28.00 x 18.50 x 29.00 mm). Physical interchange is not possible in space-constrained PCB layouts. Both support higher current ratings (6A) and lower DC resistance values.

Q: Which substitute part has the lowest DC resistance?

A: SC-06-35J provides the lowest DC resistance at 50 mOhm, followed by SCR22-050-0R9A090J at 55 mOhm. The original SC22-05-70J and SC-06-60J both specify 60 mOhm maximum DC resistance.

Q: Can I use SC22-05-30J as a direct replacement for SC22-05-70J?

A: SC22-05-30J is a valid substitute with identical physical dimensions and mounting configuration. It provides 3 mH inductance at 10 kHz versus 7 mH in the original part. Substitution is appropriate when the application requires lower inductance values and maintains all other electrical and compliance requirements.
