Substitute Part Grouping Explanation

The SC-18-085J qualifies as a parametric equivalent within the SC-J series based on the following allowed substitution criteria:

Maintained Parameters:

• Manufacturer: KEMET (same manufacturer)
• Series: SC-J (same product line)
• Number of Lines: 2 (identical configuration)
• Current Rating: 18A (identical maximum current)
• Voltage Rating: 250V DC/AC (identical voltage specifications)
• Operating Temperature: -40°C to 120°C (identical range)
• Mounting Type: Through Hole (identical mounting)
• Physical Dimensions: 36.00mm L x 25.00mm W x 35.00mm H (identical footprint)
• Package / Case: Vertical, 4 PC Pin (identical package)
• RoHS Status: ROHS3 Compliant (equivalent compliance)
• Product Status: Active (current availability)

Varied Parameters:

• Inductance @ 10 kHz: 850 µH (versus 950 µH in main part)
• DC Resistance (Max): 6mOhm (versus 5.5mOhm in main part)

The SC-18-085J operates within the same electrical class and physical envelope, with inductance and DCR variations that remain within acceptable tolerances for common mode choke applications in this category.

Parameter Comparison

Engineering Selection Recommendations

Both SC-18-095J and SC-18-085J maintain active product status with ROHS3 compliance and REACH unaffected designation. Selection between these parts is determined by application-specific inductance and resistance requirements. The SC-18-095J provides 950 µH inductance with 5.5mOhm DCR, while the SC-18-085J provides 850 µH inductance with 6mOhm DCR. Both components share identical current ratings, voltage specifications, temperature operating range, and physical footprint, enabling direct board-level substitution when inductance and resistance tolerances permit.

Frequently Asked Questions (FAQ)

Q: Can SC-18-085J replace SC-18-095J in any application?

A: Substitution is valid only when the application circuit tolerates the inductance reduction from 950 µH to 850 µH and the DCR increase from 5.5mOhm to 6mOhm. Both parts maintain identical current and voltage ratings.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both SC-18-095J and SC-18-085J share identical dimensions of 36.00mm L x 25.00mm W x 35.00mm H with vertical, 4 PC pin packaging, enabling direct PCB footprint compatibility.

Q: Do both parts meet the same compliance standards?

A: Both parts are ROHS3 compliant, REACH unaffected, and maintain active product status. Compliance certifications are equivalent.

Q: What is the primary difference between these substitute parts?

A: The primary differences are inductance value (950 µH versus 850 µH at 10 kHz) and maximum DC resistance (5.5mOhm versus 6mOhm). All other electrical and mechanical parameters remain identical.

Q: Are these parts from the same manufacturer series?

A: Yes. Both SC-18-095J and SC-18-085J belong to the KEMET SC-J series, ensuring design consistency and compatibility within the product line.
