Substitute Part Grouping Explanation

Substitution logic is based on the following critical parameters that must remain constant or compatible:

Mandatory Matching Parameters:

Capacitance: 22 µF (exact match required)
Tolerance: ±20% (exact match required)
Mounting Type: Surface Mount (exact match required)
Package: Radial, Can - SMD (exact match required)
Land Size: 0.169" L x 0.169" W (4.30 mm x 4.30 mm) (exact match required)
Operating Temperature Range: -55°C to 105°C (exact match required)
Lifetime @ 105°C: 2000 Hrs (exact match required)
AEC-Q200 Rating: Yes (exact match required)
RoHS Status: ROHS3 Compliant (exact match required)

Allowable Variation Parameters:

Voltage Rating: 10 V (main part) to 35 V (substitutes) — higher voltage ratings are acceptable as they provide superior voltage margin
ESR @ 100 kHz: 850 mOhm (main part) to unspecified (substitutes) — lower or equivalent ESR is acceptable
Ripple Current: 104 mA @ 120 Hz and 160 mA @ 100 kHz (main part) — equal or higher ripple current capability is acceptable
Height (Max): 0.228" to 0.240" (5.80 mm to 6.10 mm) — minor height variation within PCB assembly constraints
Manufacturer: Panasonic, Chemi-Con, Rubycon — different manufacturers with equivalent certifications

Substitutes are grouped into two categories: Direct Equivalents (same voltage rating) and Upgrade Options (higher voltage ratings for enhanced reliability margin).

Engineering Selection Recommendations

Direct Equivalents (Same Voltage Rating — 10 V):

EEE-FK1A220AR and EMZA100ARA220MD61G are direct electrical equivalents with identical voltage and capacitance ratings. Both maintain AEC-Q200 automotive qualification and ROHS3 compliance. Height variation (0.240" vs. 0.228") is within typical PCB assembly tolerances. Selection between these parts depends on manufacturer preference and supply availability.

Upgrade Options (Higher Voltage Ratings):

Parts rated at 16 V, 25 V, and 35 V are suitable substitutes when higher voltage margin is required. These upgrades provide enhanced reliability in applications subject to voltage transients or where design margin improvement is specified. All upgrade options maintain identical capacitance, tolerance, operating temperature range, lifetime rating, and AEC-Q200 qualification.

EEE-FPC220UAR (16 V, Panasonic FP series) preserves the original 850 mOhm ESR and 160 mA ripple current specifications while offering increased voltage headroom. This part is the closest electrical match to the main part.

EEE-FT1E220AR (25 V) and EEE-FT1V220AR (35 V) provide maximum voltage margin with identical ESR and ripple current performance. These are suitable for applications requiring enhanced transient protection.

Manufacturer Alternatives:

Chemi-Con (EMZA series) and Rubycon (TZV series) parts meet all mandatory electrical and mechanical specifications with AEC-Q200 qualification. These alternatives support supply chain diversification while maintaining automotive-grade reliability.

Frequently Asked Questions (FAQ)

Q: Can I use a 16 V rated capacitor in place of a 10 V rated capacitor?

A: Yes. Higher voltage-rated capacitors are electrically compatible substitutes. The 16 V, 25 V, and 35 V rated parts listed are direct substitutes that provide superior voltage margin without affecting circuit performance. All maintain identical capacitance, tolerance, and operating temperature specifications.

Q: What is the significance of ESR (Equivalent Series Resistance)?

A: ESR affects ripple current handling and thermal performance. The main part specifies 850 mOhm @ 100 kHz. Substitute parts with unspecified ESR or lower ESR values are acceptable. Lower ESR generally improves thermal performance under ripple current stress.

Q: Are there height restrictions for PCB assembly?

A: The main part height is 0.228" (5.80 mm). Substitute parts with 0.240" (6.10 mm) height are acceptable within standard PCB assembly clearance tolerances. Verify clearance with your specific PCB layout and component placement constraints.

Q: Do all substitute parts have AEC-Q200 qualification?

A: Yes. All listed substitute parts carry AEC-Q200 automotive qualification, ensuring compliance with automotive reliability and qualification standards.

Q: What is the difference between Panasonic FP, FK, and FT series?

A: These are different Panasonic product lines with varying voltage ratings and performance characteristics. FP series (10 V and 16 V) and FT series (25 V and 35 V) maintain 850 mOhm ESR and 160 mA ripple current. FK series offers lower ripple current (90 mA @ 100 kHz) with unspecified ESR. Selection depends on ripple current requirements and voltage margin needs.

Q: Can I substitute a Chemi-Con or Rubycon part for a Panasonic part?

A: Yes. EMZA series (Chemi-Con) and TZV series (Rubycon) parts meet all mandatory electrical and mechanical specifications with AEC-Q200 qualification. Manufacturer substitution is supported for supply chain flexibility.

Q: What does ROHS3 compliance mean?

A: ROHS3 (Restriction of Hazardous Substances Directive 3) compliance indicates the part meets European environmental regulations restricting hazardous materials. All listed parts are ROHS3 compliant.

Q: Is MSL 1 (Unlimited) moisture sensitivity important?

A: MSL 1 indicates unlimited shelf life without moisture bake-out requirements. All listed parts carry MSL 1 rating, eliminating moisture-related handling constraints during storage and assembly.
