Substitute Part Grouping Explanation

Substitution is determined by the following criteria:

Direct Equivalents (Same Voltage, Same Lifetime Class): Parts maintaining 200 V rating and 2000 hour lifetime at 85°C. These provide pin-for-pin compatibility with identical electrical performance.

Enhanced Reliability Substitutes (Same Voltage, Extended Lifetime): Parts maintaining 200 V rating but offering extended lifetime ratings (4000 hours at 125°C or 12000 hours at 105°C). These are suitable for applications requiring improved long-term reliability without circuit redesign.

Upgraded Voltage Substitutes (250 V Rating): Parts rated at 250 V with equivalent or superior lifetime characteristics. These provide overvoltage margin and are backward-compatible in 200 V applications.

All substitute parts maintain identical capacitance (3.3 µF), tolerance (±20%), polarization (polar), package type (radial can), mounting type (through hole), lead spacing (2.50 mm), and case diameter (6.30 mm). All parts are ROHS3 compliant and REACH unaffected.

Engineering Selection Recommendations

For Direct Replacement (Identical Performance): Select 200PK3.3MEFC6.3X11 (Rubycon PK series). This part maintains the original 200 V rating, 2000 hour lifetime at 85°C, and identical operating temperature range. It is active status and ROHS3 compliant. Height variation (0.512" vs. 0.492") must be verified against PCB layout constraints.

For Enhanced Reliability (Same Voltage, Extended Life): Select 200LLE3.3MEFC6.3X11 or 200LLE3R3MEFC6.3X11 (Rubycon LLE series). These parts provide 12000 hour lifetime at 105°C while maintaining 200 V rating and identical footprint compatibility. Operating temperature range extends to 105°C. Height of 200LLE3.3MEFC6.3X11 matches original at 0.492", while 200LLE3R3MEFC6.3X11 is 0.512".

For Overvoltage Margin (Upgraded Voltage): Select 250LEX3.3MEFC6.3X11, 250LEX3R3MEFC6.3X11, 250LLE3.3MEFC6.3X11, 250LLE3R3MEFCT16.3X11, or 250PK3.3MEFC6.3X11. These parts provide 250 V rating with backward compatibility in 200 V applications. All are active status and ROHS3 compliant. Selection depends on required lifetime rating and operating temperature range.

All substitute parts are active production items with confirmed inventory availability and comply with ROHS3 and REACH requirements.

Frequently Asked Questions (FAQ)

Q: Can 200PK3.3MEFC6.3X11 be used as a direct replacement for UVR2D3R3MED?

A: Yes. Both parts share identical electrical specifications: 3.3 µF capacitance, ±20% tolerance, 200 V rating, 2000 hour lifetime at 85°C, and -40°C to 85°C operating range. Lead spacing (2.50 mm) and case diameter (6.30 mm) are identical. Height difference (0.512" vs. 0.492") requires PCB layout verification.

Q: What is the advantage of selecting LLE series parts over the original UVR series?

A: LLE series parts (200LLE3.3MEFC6.3X11, 200LLE3R3MEFC6.3X11) provide extended lifetime of 12000 hours at 105°C compared to 2000 hours at 85°C for the original. This improves long-term reliability in applications subject to sustained thermal stress. Electrical specifications and footprint remain compatible.

Q: Are 250 V rated parts suitable for 200 V applications?

A: Yes. Parts rated at 250 V (250LEX3.3MEFC6.3X11, 250LLE3.3MEFC6.3X11, 250PK3.3MEFC6.3X11) are backward-compatible in circuits designed for 200 V operation. The higher voltage rating provides additional safety margin and does not affect circuit function. Capacitance, tolerance, and package remain identical.

Q: What is the difference between 200LEX3.3MEFC6.3X11 and 200LEX3R3MEFC6.3X11?

A: Both parts are Rubycon LEX series with identical electrical specifications: 3.3 µF, 200 V, 4000 hour lifetime at 125°C. The primary difference is ripple current capability at high frequency: 200LEX3R3MEFC6.3X11 supports 84 mA @ 100 kHz versus unspecified for 200LEX3.3MEFC6.3X11. Both have 0.512" maximum height.

Q: Does height variation affect PCB compatibility?

A: Height differences between 0.492" (original, 200LLE3.3MEFC6.3X11, 250PK3.3MEFC6.3X11) and 0.512" (most Rubycon substitutes) must be evaluated against PCB clearance, component spacing, and enclosure constraints. Lead spacing and case diameter remain constant across all parts.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts are ROHS3 compliant and REACH unaffected, matching the compliance status of the original UVR2D3R3MED.
