Substitute Part Grouping Explanation

Substitution for the UPB1V221MPD is determined by strict adherence to the following electrical and mechanical parameters:

Critical Matching Parameters:

Capacitance: 220 µF (exact match required)
Voltage Rating: 35 V (exact match required)
Tolerance: ±20% (exact match required)
Polarization: Polar (exact match required)
Mounting Type: Through Hole (exact match required)
Package Type: Radial, Can (exact match required)

Mechanical Compatibility Parameters:

Lead Spacing: 0.197" (5.00mm) — determines PCB hole pattern compatibility
Size / Dimension: 0.394" Dia (10.00mm) — determines board layout fit
Height - Seated (Max): 0.551" (14.00mm) — determines vertical clearance requirements

Performance Parameters:

Operating Temperature Range: -40°C ~ 105°C (minimum requirement)
Lifetime @ 105°C: 7000 Hrs (baseline; higher values acceptable)
Ripple Current Ratings @ 120 Hz and 100 kHz (baseline; higher values acceptable)

Substitute parts must match all critical parameters exactly. Variations in mechanical dimensions, lead spacing, or performance ratings outside the specified tolerances render a part incompatible for direct substitution.

Engineering Selection Recommendations

Direct Mechanical and Electrical Match:

UHD1V221MPD6 provides exact mechanical compatibility with the UPB1V221MPD, matching lead spacing (0.197" / 5.00mm), case diameter (0.394" / 10.00mm), and seated height (0.551" / 14.00mm). This part maintains identical electrical specifications: 220 µF capacitance, 35 V rating, and ±20% tolerance. Although the lifetime rating is 4000 hours at 105°C compared to the original 7000 hours, this part is suitable for applications where the reduced lifetime is acceptable. UHD1V221MPD6 carries RoHS3 compliance.

Active Product with Enhanced Performance:

B41888C7227M from EPCOS - TDK Electronics is an active product offering 7000-hour lifetime at 105°C, matching the original part's endurance rating. Mechanical dimensions align closely: 0.197" (5.00mm) lead spacing, 0.394" (10.00mm) case diameter, and 0.531" (14.60mm) seated height. The slight height reduction (0.020" / 0.5mm) may provide additional clearance in space-constrained layouts. This part carries AEC-Q200 automotive qualification and RoHS3 compliance, making it suitable for automotive and industrial applications requiring higher reliability standards.

Active Panasonic Alternative:

EEU-FM1V221 from Panasonic Electronic Components matches the UPB1V221MPD in all mechanical dimensions: 0.197" (5.00mm) lead spacing, 0.394" (10.00mm) case diameter, and 0.551" (14.00mm) seated height. Electrical specifications are identical. The part is active and RoHS3 compliant. Lifetime rating is 4000 hours at 105°C. This option provides broad availability and active product status.

Mechanical Incompatibility Note:

Parts with 0.138" (4.60mm) lead spacing—including UHD1V221MPD, UHE1V221MPD, UHV1V221MPD, EEU-EB1V221, EEU-EB1V221BJ, and EEU-EB1V221B—are not direct substitutes for the UPB1V221MPD due to different PCB hole pattern requirements. These parts require board redesign and are suitable only for new designs or retrofit applications where PCB modification is feasible.

Frequently Asked Questions (FAQ)

Q: Can I use UHD1V221MPD as a direct replacement for UPB1V221MPD?

A: No. UHD1V221MPD has 0.138" (4.60mm) lead spacing and 0.315" (8.00mm) case diameter, which differ from the UPB1V221MPD's 0.197" (5.00mm) lead spacing and 0.394" (10.00mm) case diameter. These dimensional differences prevent direct PCB compatibility.

Q: What is the difference between UHD1V221MPD6 and UHD1V221MPD?

A: Both parts share the same electrical specifications (220 µF, 35 V, ±20% tolerance) but differ in mechanical dimensions and lifetime ratings. UHD1V221MPD6 has 0.197" (5.00mm) lead spacing and 0.551" (14.00mm) height with 4000-hour lifetime, while UHD1V221MPD has 0.138" (4.60mm) lead spacing and 0.650" (16.50mm) height with 3000-hour lifetime. Only UHD1V221MPD6 is mechanically compatible with the UPB1V221MPD.

Q: Why is B41888C7227M recommended despite being from a different manufacturer?

A: B41888C7227M matches all critical mechanical parameters (lead spacing, case diameter, height) and maintains the 7000-hour lifetime rating at 105°C. It is an active product with AEC-Q200 automotive qualification and RoHS3 compliance, providing superior product status and reliability certification compared to obsolete or "not for new designs" alternatives.

Q: Can I substitute EEU-FM1V221 for UPB1V221MPD?

A: Yes, mechanically and electrically. EEU-FM1V221 matches all dimensional requirements: 0.197" (5.00mm) lead spacing, 0.394" (10.00mm) case diameter, and 0.551" (14.00mm) height. Electrical specifications are identical. The part is active and RoHS3 compliant. Lifetime is 4000 hours at 105°C versus the original 7000 hours.

Q: What does "Not For New Designs" product status mean?

A: Parts marked "Not For New Designs" are available for existing production and maintenance but are not recommended for new product development. These parts may have limited future availability or are being phased out by manufacturers. For new designs, active products such as B41888C7227M or EEU-FM1V221 are preferred.

Q: Are all substitute parts RoHS3 compliant?

A: No. The original UPB1V221MPD is listed as "REACH Unaffected." Among substitutes, B41888C7227M and all Panasonic EEU series parts (EEU-EB1V221, EEU-EB1V221B, EEU-EB1V221BJ, EEU-FM1V221) are RoHS3 compliant. Nichicon UHE and UHV series parts are RoHS3 compliant but marked as "REACH Affected."

Q: What is the impact of different ripple current ratings?

A: Ripple current capacity determines the maximum AC current the capacitor can handle without exceeding temperature limits. Higher ripple current ratings indicate better thermal performance. The UPB1V221MPD handles 200 mA @ 120 Hz and 260 mA @ 100 kHz. Substitutes with higher ratings (such as EEU-FM1V221 at 903 mA @ 120 Hz and 1.29 A @ 100 kHz) provide additional margin but are not required for direct compatibility.
