Substitute Part Grouping Explanation

Substitution of the SFJEC2K00331MC0 is determined by strict equivalence across the following electrical and mechanical parameters:

• Capacitance value: 330 pF (exact match required)
• Voltage rating: 2000V minimum (2kV)
• Current rating: 15 A minimum
• Temperature coefficient: C0G or NP0
• Operating temperature range: -55°C to 125°C minimum
• Insertion loss: 13 dB @ 100 MHz
• Package configuration: Axial, bushing mount
• Physical dimensions: 0.386" Dia × 0.370" L (9.80 mm × 9.40 mm)
• RoHS compliance: ROHS3 Compliant

The SFJNC2K00331MC0 meets all electrical specifications and maintains the same physical footprint and performance characteristics. The primary distinction is the thread size specification (1/4-28 versus M6×0.75), which reflects design evolution within the active product series.

Parameter Comparison

Engineering Selection Recommendations

The SFJNC2K00331MC0 is the direct active-product substitute for the obsolete SFJEC2K00331MC0. Both components are manufactured by Knowles Syfer and maintain identical electrical performance specifications, including capacitance, voltage rating, current handling, temperature stability, and insertion loss characteristics. Both are ROHS3 compliant.

The transition from the SFJEC to SFJNC series reflects standard product line evolution. The thread size difference (1/4-28 to M6×0.75) represents a design update within the active product family. Component selection should be based on mechanical mounting requirements specific to the application.

Frequently Asked Questions (FAQ)

Q: Can the SFJNC2K00331MC0 be used as a direct replacement for the SFJEC2K00331MC0?

A: Yes. Both components share identical electrical specifications: 330 pF capacitance, 2000V rating, 15 A current capacity, C0G/NP0 temperature coefficient, -55°C to 125°C operating range, and 13 dB insertion loss @ 100 MHz. Physical dimensions are identical (0.386" Dia × 0.370" L). The thread size differs (1/4-28 versus M6×0.75), which must be evaluated against mechanical mounting requirements.

Q: What is the significance of the thread size change from 1/4-28 to M6×0.75?

A: Thread size determines the mechanical mounting interface. The 1/4-28 specification uses UNC (Unified National Coarse) threading, while M6×0.75 uses metric threading. Selection depends on the mounting hardware and panel specifications of the application. Both provide equivalent mechanical function within their respective threading standards.

Q: Are both parts RoHS compliant?

A: Yes. Both the SFJEC2K00331MC0 and SFJNC2K00331MC0 are ROHS3 compliant.

Q: What is the availability status of each part?

A: The SFJEC2K00331MC0 is obsolete with 1067 pieces in stock. The SFJNC2K00331MC0 is active with 855 pieces in stock, representing the current production line.
