Substitute Part Grouping Explanation

Substitution eligibility for the SFJEC5000473MX0 is determined by strict equivalence across the following critical parameters:

• Capacitance value: 0.047 µF (exact match required)
• Voltage rating: 500V (exact match required)
• Current capacity: 15 A (exact match required)
• Temperature coefficient: X7R (exact match required)
• Operating temperature range: -55°C to 125°C (exact match required)
• Tolerance: ±20% (exact match required)
• Package configuration: Axial, Bushing (exact match required)
• Physical dimensions: 0.386" Dia × 0.370" L (exact match required)
• RoHS compliance: ROHS3 Compliant (exact match required)

The SFJNC5000473MX0 meets all substitution criteria as a direct equivalent, with the primary distinction being its active product status and updated thread specification (M6×0.75 versus 1/4-28).

Parameter Comparison

Engineering Selection Recommendations

The SFJNC5000473MX0 is the direct substitute for the obsolete SFJEC5000473MX0. Both components are manufactured by Knowles Syfer and maintain identical electrical and mechanical specifications across all critical parameters. The substitute part offers the advantage of active product status, ensuring long-term availability and supply chain continuity.

Both parts maintain ROHS3 compliance and are suitable for applications requiring 0.047 µF capacitance at 500V with 15 A current handling. The primary consideration during integration is the thread specification difference: the obsolete part uses 1/4-28 threading while the active substitute uses M6×0.75 threading. This difference requires mechanical accommodation in the mounting interface but does not affect electrical performance.

Frequently Asked Questions (FAQ)

Q: Can SFJNC5000473MX0 be used as a direct replacement for SFJEC5000473MX0?

A: Yes. Both parts are electrically and mechanically equivalent across all specified parameters, including capacitance, voltage rating, current capacity, temperature range, and physical dimensions. The thread specification differs (1/4-28 versus M6×0.75), requiring mechanical interface verification during installation.

Q: What is the significance of the product status change from Obsolete to Active?

A: The active status of SFJNC5000473MX0 indicates ongoing manufacturing and availability. This ensures reliable procurement for new designs and system maintenance without supply constraints associated with obsolete components.

Q: Are both parts RoHS compliant?

A: Yes. Both SFJEC5000473MX0 and SFJNC5000473MX0 are ROHS3 compliant, meeting environmental and regulatory requirements for electronic component manufacturing and use.

Q: Does the thread size difference affect electrical performance?

A: No. The thread specification difference (1/4-28 versus M6×0.75) is a mechanical interface parameter only. Electrical performance, including capacitance, voltage rating, and current handling, remains identical between both parts.

Q: What inventory considerations should be evaluated?

A: Both parts maintain comparable inventory levels (727 pcs for SFJEC5000473MX0 and 722 pcs for SFJNC5000473MX0). For new procurement, the active status of SFJNC5000473MX0 provides superior long-term availability assurance.
