Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HT55BB562KC is determined by strict adherence to the following electrical and mechanical parameters:

Electrical Parameters (Non-negotiable):

• Capacitance value: 5600 pF
• Voltage rating: 50V minimum
• Tolerance: ±10% or tighter
• Temperature coefficient: X7R
• Operating temperature range: -55°C to 200°C minimum

Mechanical Parameters (Non-negotiable):

• Mounting type: Through Hole
• Package type: Radial
• Lead spacing: 0.200" (5.08mm)
• Lead style: Straight or formed leads compatible with 0.200" spacing

The C052H562K5R5GA meets all substitution criteria. While dimensional variations exist in body size and height, the critical lead spacing of 0.200" (5.08mm) remains constant, ensuring PCB footprint compatibility. The substitute part maintains identical electrical specifications and operates within the same temperature range.

Engineering Selection Recommendations

The C052H562K5R5GA is the qualified substitute for the obsolete HT55BB562KC based on the following engineering criteria:

Electrical Equivalence: Both parts share identical capacitance (5600 pF), voltage rating (50V), tolerance (±10%), temperature coefficient (X7R), and operating temperature range (-55°C to 200°C). These parameters ensure functional interchangeability in circuit applications.

Mechanical Compatibility: The critical lead spacing of 0.200" (5.08mm) is maintained, ensuring direct PCB footprint compatibility. While the substitute features formed leads rather than straight leads, this variation is compatible with standard through-hole PCB mounting practices.

Product Status and Compliance: The substitute part is active in production, ensuring long-term availability. The C052H562K5R5GA carries ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements that may not have applied to the obsolete HT55BB562KC.

Series Continuity: Both parts belong to KEMET's industrial-grade X7R ceramic capacitor lines designed for high-temperature applications, maintaining design intent and performance characteristics.

Frequently Asked Questions (FAQ)

Q: Can the C052H562K5R5GA be used as a direct replacement for HT55BB562KC on existing PCBs?

A: Yes. The substitute part maintains the 0.200" (5.08mm) lead spacing required for PCB footprint compatibility. The formed leads of the substitute are compatible with standard through-hole mounting. No PCB redesign is necessary.

Q: Are there electrical performance differences between the main part and substitute?

A: No. Both parts have identical capacitance (5600 pF), voltage rating (50V), tolerance (±10%), temperature coefficient (X7R), and operating temperature range (-55°C to 200°C). Electrical performance is equivalent.

Q: Why does the substitute part have different physical dimensions?

A: The C052H562K5R5GA has a slightly smaller body (0.190" L x 0.090" W versus 0.200" L x 0.100" W) but maintains the same lead spacing. This dimensional variation reflects manufacturing improvements in the active product line and does not affect PCB compatibility or electrical function.

Q: What is the significance of the substitute part being ROHS3 compliant?

A: ROHS3 compliance indicates the substitute meets current environmental and regulatory standards for restricted substances. This is advantageous for new designs and systems requiring compliance with modern regulations.

Q: Are there any application differences between the two parts?

A: The main part is specified for general-purpose applications, while the substitute is specified for bypass and decoupling applications. Both specifications are compatible with general-purpose use. The substitute's low ESL feature provides additional performance benefit for high-frequency bypass applications.

Q: Is inventory availability a consideration for substitution?

A: The substitute part (C052H562K5R5GA) is active in production with 694 pieces in stock, compared to the obsolete main part with 758 pieces in stock. The active status of the substitute ensures continued availability for future requirements.
