Substitute Part Grouping Explanation

Substitution eligibility for the UVR1A102MPD is determined by strict equivalence in the following parameters:

• Capacitance: 1000 µF (exact match required)
• Voltage Rating: 10 V (exact match required)
• Tolerance: ±20% (exact match required)
• Lifetime @ Temperature: 2000 Hrs @ 85°C (exact match required)
• Operating Temperature Range: -40°C ~ 85°C (exact match required)
• Lead Spacing: 0.197" (5.00mm) (exact match required)
• Package Type: Radial, Can (exact match required)
• Mounting Type: Through Hole (exact match required)
• RoHS Status: ROHS3 Compliant (exact match required)

Substitute parts are categorized as follows:

Upgrade Substitutes (UFW1A102MPD, UKW1A102MPD): Nichicon parts with identical electrical and mechanical specifications. These parts meet all equivalence criteria and represent alternative series within the same manufacturer's portfolio.

Similar Substitutes (URS1A102MPD, UVK1A102MPD): Nichicon parts meeting all core electrical specifications. URS1A102MPD is Active status. UVK1A102MPD shares identical ripple current ratings with the main part.

Direct Substitutes (ECA-1AM102, ECA-1AM102B): Panasonic parts with identical electrical specifications and Active product status. These represent cross-manufacturer equivalents.

Similar Cross-Manufacturer Substitute (SK102M010ST): Cornell Dubilier Electronics part meeting electrical specifications with documented ESR of 250mOhm and Active status. Height dimension differs (0.787" vs. 0.492").

Parameter Comparison

Engineering Selection Recommendations

For PCB Space-Constrained Applications: UFW1A102MPD and UKW1A102MPD maintain the original 12.50mm height, providing direct mechanical compatibility with existing board layouts. Both are Nichicon products with Not For New Designs status.

For Active Product Line Preference: ECA-1AM102 and ECA-1AM102B (Panasonic, Active status) or URS1A102MPD (Nichicon, Active status) are recommended. These parts ensure continued manufacturer support and availability. ECA-1AM102B has the highest inventory level (11,911 pcs) among all substitutes.

For Cross-Manufacturer Flexibility: ECA-1AM102 and ECA-1AM102B provide Panasonic equivalents with Active product status and higher ripple current capability at 10 kHz (1.071 A vs. 747.5 mA for the main part).

For Height-Tolerant Applications: URS1A102MPD and UVK1A102MPD accommodate 14.00mm height. URS1A102MPD offers Active status and lower ripple current (620 mA @ 120 Hz).

For Specialized Applications: SK102M010ST (Cornell Dubilier) is Active status with documented 250mOhm ESR but requires 20.00mm clearance and lacks published ripple current data.

All substitute parts maintain ROHS3 compliance and -40°C ~ 85°C operating temperature range.

Frequently Asked Questions (FAQ)

Q: Can UFW1A102MPD directly replace UVR1A102MPD on the same PCB?

A: Yes. UFW1A102MPD shares identical lead spacing (5.00mm) and height (12.50mm), enabling direct mechanical substitution. Electrical specifications match across capacitance, voltage, tolerance, and lifetime ratings. Ripple current is slightly lower (630 mA vs. 650 mA @ 120 Hz), which is acceptable for general-purpose applications.

Q: What is the difference between UKW1A102MPD and UFW1A102MPD?

A: Both parts are Nichicon 1000 µF, 10 V radial capacitors with identical electrical and mechanical specifications. The difference lies in internal series designation (UKW vs. UFW). Both are Not For New Designs status. Selection between them depends on inventory availability and application-specific requirements.

Q: Why does ECA-1AM102B have higher inventory than ECA-1AM102?

A: Both are Panasonic equivalents with identical specifications. ECA-1AM102B represents a variant within the M-A series with higher stock availability. Both are Active products suitable for new designs.

Q: Can SK102M010ST be used in space-constrained applications?

A: No. SK102M010ST requires 20.00mm height compared to the original 12.50mm, making it unsuitable for existing PCB layouts. It is appropriate only for applications with height tolerance or redesigned board layouts.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance, matching the original UVR1A102MPD specification.

Q: Which substitute offers the best long-term availability?

A: ECA-1AM102B (Panasonic, Active status) with 11,911 pcs inventory represents the highest availability among all substitutes. URS1A102MPD (Nichicon, Active status) with 857 pcs also provides Active product line support.

Q: Do ripple current differences affect substitution suitability?

A: Ripple current variations among substitutes (630–1,071 mA @ 10 kHz) remain within acceptable ranges for equivalent 1000 µF, 10 V applications. Higher ripple current capability (ECA-1AM102, ECA-1AM102B at 1.071 A) provides additional thermal margin. Selection depends on circuit ripple current requirements.
