Engineering Selection Recommendations

Parametric Equivalent - EMVY500ARA4R7ME55G (Chemi-Con)

The EMVY500ARA4R7ME55G represents the closest parametric equivalent to the obsolete MVY50VC4R7ME55TP. This part maintains identical electrical specifications (4.7 µF, 50 V, ±20%, 1000 Hrs @ 105°C) and mechanical dimensions (0.197" Dia, 0.205" height). The primary advantage is active product status with ROHS3 compliance, making it suitable for new designs and ongoing production. The Alchip™- MVY series designation indicates continued support from Chemi-Con. This part is recommended as the primary replacement for direct substitution in existing designs.

Direct Equivalents - AVES475M50C12T-F and AVEZ475M50C12T-F (Cornell Dubilier Electronics)

Both Cornell Dubilier parts meet the core electrical requirements (4.7 µF, 50 V, ±20%, 1000 Hrs @ 105°C) and are ROHS3 compliant with active product status. The AVEZ475M50C12T-F maintains the 3 Ohm impedance specification matching the original part and offers 50 mA ripple current at 100 kHz. The AVES475M50C12T-F exhibits higher impedance (42.3 Ohm @ 120Hz) and reduced ripple current (25.5 mA @ 10 kHz), making it suitable for applications with lower ripple current demands. Both parts feature slightly increased height (0.217" vs. 0.205"), which must be verified against PCB clearance constraints.

Upgrade Options - EXV475M050A9DAA and EXV475M050S9DAA (KEMET)

The KEMET EXV series parts provide enhanced performance characteristics with extended lifetime (3000 Hrs @ 105°C versus 1000 Hrs) and increased ripple current capacity (95 mA @ 100 kHz). Both parts maintain the core electrical specifications (4.7 µF, 50 V, ±20%) and are ROHS3 compliant. The EXV475M050S9DAA includes AEC-Q200 automotive qualification and is designated for automotive applications. These parts feature slightly increased height (0.222" vs. 0.205%) and are suitable for applications requiring enhanced reliability or higher ripple current handling. The upgrade path is appropriate for designs with extended operational demands or automotive requirements.

Alternative - UWT1H4R7MCL1GB (Nichicon)

The Nichicon UWT1H4R7MCL1GB meets all core electrical specifications (4.7 µF, 50 V, ±20%, 1000 Hrs @ 105°C) and is ROHS3 compliant with active product status. This part features the lowest height profile (0.213" vs. 0.205" original) and maintains compatibility with the standard land size. Ripple current specification (28.5 mA @ 10 kHz) is lower than the original part, requiring application-specific evaluation. This part is suitable for space-constrained designs where height minimization is critical.

Frequently Asked Questions (FAQ)

Q: Can I use AVES475M50C12T-F as a direct replacement for MVY50VC4R7ME55TP?

A: The AVES475M50C12T-F meets all core electrical requirements (4.7 µF, 50 V, ±20%, 1000 Hrs @ 105°C) and physical land size specifications. However, the impedance specification differs (42.3 Ohm @ 120Hz versus 3 Ohms), and ripple current at 100 kHz is reduced (25.5 mA @ 10 kHz versus 50 mA @ 100 kHz). Substitution is valid only if the application does not require the original impedance or ripple current characteristics. Height is increased by 0.012" (0.30mm), requiring PCB clearance verification.

Q: What is the advantage of selecting EXV475M050S9DAA over EMVY500ARA4R7ME55G?

A: The EXV475M050S9DAA provides extended lifetime (3000 Hrs @ 105°C versus 1000 Hrs) and higher ripple current capacity (95 mA @ 100 kHz versus 50 mA @ 100 kHz). Additionally, this part carries AEC-Q200 automotive qualification, making it suitable for automotive applications. Selection depends on application requirements for reliability margin and ripple current handling. The trade-off is increased height (0.222" versus 0.205"), which must be accommodated in the PCB design.

Q: Are all substitute parts RoHS compliant?

A: All substitute parts listed (EMVY500ARA4R7ME55G, AVES475M50C12T-F, AVEZ475M50C12T-F, EXV475M050A9DAA, EXV475M050S9DAA, and UWT1H4R7MCL1GB) are ROHS3 compliant. The original MVY50VC4R7ME55TP is RoHS non-compliant. Substitution with any of these parts satisfies RoHS compliance requirements for new designs.

Q: What is the difference between AVEZ475M50C12T-F and AVES475M50C12T-F?

A: Both parts are manufactured by Cornell Dubilier Electronics and meet the core electrical specifications. The primary differences are: AVEZ475M50C12T-F maintains 3 Ohm impedance and 50 mA ripple current @ 100 kHz (matching the original part), while AVES475M50C12T-F exhibits 42.3 Ohm impedance @ 120Hz and 25.5 mA ripple current @ 10 kHz. The AVEZ series is recommended for direct substitution when impedance and ripple current characteristics are critical to circuit performance.

Q: Can I use UWT1H4R7MCL1GB in space-constrained applications?

A: Yes. The UWT1H4R7MCL1GB features a height of 0.213" (5.40mm), which is lower than most substitute options and only 0.008" (0.20mm) higher than the original part. This part is suitable for applications with minimal vertical clearance. However, ripple current specification (28.5 mA @ 10 kHz) is lower than the original 50 mA @ 100 kHz, requiring verification that the application does not demand higher ripple current handling.

Q: Is the surface mount land size identical across all substitute parts?

A: Yes. All substitute parts maintain the identical surface mount land size of 0.209" L x 0.209" W (5.30mm x 5.30mm), ensuring PCB footprint compatibility. Height variations range from 0.205" to 0.222", which must be evaluated for component clearance and assembly considerations.

Q: Which substitute part offers the best overall compatibility?

A: The EMVY500ARA4R7ME55G (Chemi-Con Alchip™- MVY series) provides the closest parametric match with identical height (0.205"), impedance (3 Ohms), and ripple current (50 mA @ 100 kHz) specifications. This part is recommended as the primary replacement for direct substitution in existing designs requiring minimal circuit re-evaluation.
