Package Type: Radial, Can - SMD (physical form factor)
Case Diameter: 0.315" (8.00 mm)
Land Size: 0.327" L x 0.327" W (8.30 mm x 8.30 mm)
Mounting Type: Surface Mount
Operating Temperature: -40°C to 125°C minimum
Polarization: Polar

Secondary Performance Parameters:

ESR (Equivalent Series Resistance): Lower values indicate improved performance
Lifetime @ 125°C: Equal or greater duration acceptable
Ripple Current Capability: Higher values indicate enhanced performance margin

Substitute parts are classified into three categories:

Direct Equivalents (Same Voltage Rating - 50V): Parts maintaining identical 50 V voltage rating with compatible physical dimensions and electrical characteristics.

Voltage Upgrades (Higher Voltage Rating): Parts with 63 V or 80 V ratings that maintain all other parameters, providing enhanced voltage margin while remaining physically compatible.

Performance Upgrades: Parts with improved ESR, extended lifetime, or higher ripple current ratings while maintaining core electrical specifications.

Engineering Selection Recommendations

For Direct Replacement (50 V Rating, Active Status):

EMVH500ARA330MHA0G (Chemi-Con) is the primary direct equivalent. This part maintains the same manufacturer lineage (Chemi-Con MVH series), identical electrical specifications, and achieves ROHS3 compliance. The improved ESR of 700 mOhm at 100 kHz compared to the original 1 Ohm at 120 Hz provides enhanced performance characteristics. Packaging is supplied in Tape & Reel format with 1125 units in stock.

EEE-TG1H330P (Panasonic) provides an alternative direct equivalent with active product status and ROHS3 compliance. This part features 750 mOhm ESR at 100 kHz and maintains 2000-hour lifetime at 125°C. Extensive inventory availability (25,870 units) and AEC-Q200 automotive qualification support broad application compatibility.

For Applications Requiring Enhanced Performance:

50THV33M8X10.5 (Rubycon) offers performance upgrade characteristics with 360 mOhm ESR at 100 kHz and extended 3000-hour lifetime at 125°C. AEC-Q200 automotive qualification and ROHS3 compliance support demanding applications. Physical compatibility is maintained with 8.30 mm x 8.30 mm land size.

UCZ1H330MCL1GS (Nichicon) provides extended lifetime (3000 hours at 125°C) with superior ESR of 250 mOhm. Product status is "Not For New Designs," limiting application to legacy system support or existing inventory utilization.

For Voltage Margin Applications:

EEE-TG1J330UP (Panasonic) provides 63 V rating upgrade while maintaining 33 µF capacitance and 2000-hour lifetime. AEC-Q200 qualification and ROHS3 compliance support automotive applications requiring enhanced voltage headroom.

EEE-TG1K330UP (Panasonic) extends voltage rating to 80 V with identical capacitance and lifetime specifications. This option provides maximum voltage margin for applications subject to transient overvoltage conditions.

Compliance Considerations:

All recommended active-status substitutes achieve ROHS3 compliance, addressing the non-compliant status of the original MVH50VC33RMH10TP. Parts designated "Not For New Designs" (UCZ series) are suitable only for legacy system maintenance or existing inventory applications.

Frequently Asked Questions (FAQ)

Q: Can MVH50VC33RMH10TP be directly replaced with EMVH500ARA330MHA0G?

A: Yes. Both parts maintain 33 µF capacitance, 50 V rating, ±20% tolerance, identical case diameter (8.00 mm), and compatible land size (8.30 mm x 8.30 mm). EMVH500ARA330MHA0G is the direct Chemi-Con equivalent with improved ESR performance and ROHS3 compliance. Surface mount compatibility is maintained.

Q: What is the physical height difference between substitute parts?

A: The original MVH50VC33RMH10TP has a seated height of 0.394" (10.00 mm). Most substitute parts measure 0.413" (10.50 mm), representing a 0.5 mm increase. Panasonic EEE-TG series parts measure 0.402" (10.20 mm). These height variations remain within typical PCB assembly tolerances for surface mount radial can capacitors.

Q: Are voltage-upgraded parts (63V, 80V) compatible with 50V circuit designs?

A: Yes. Higher voltage-rated capacitors are electrically compatible with lower voltage applications. EEE-TG1J330UP (63 V) and EEE-TG1K330UP (80 V) maintain identical 33 µF capacitance and physical land size (8.30 mm x 8.30 mm), providing enhanced voltage margin without circuit modification. Operating temperature range remains -40°C to 125°C.

Q: What is the difference between ESR specifications at different frequencies?

A: ESR values vary with frequency due to capacitor internal impedance characteristics. The original part specifies 1 Ohm at 120 Hz. Substitute parts specify ESR at 100 kHz, representing higher frequency operation. Lower ESR values (250-750 mOhm) at 100 kHz indicate improved high-frequency performance compared to the original 1 Ohm specification.

Q: Which substitute offers the longest operational lifetime?

A: 50THV33M8X10.5 (Rubycon) and UCZ1H330MCL1GS (Nichicon) both provide 3000-hour lifetime at 125°C, compared to 2000 hours for the original part. The Rubycon part maintains active product status and ROHS3 compliance, while the Nichicon part is designated "Not For New Designs."

Q: Are all substitute parts ROHS3 compliant?

A: All substitute parts listed with active product status are ROHS3 compliant. The original MVH50VC33RMH10TP is non-compliant. Parts designated "Not For New Designs" (UCZ series) are ROHS3 compliant but unsuitable for new design implementations.

Q: What packaging formats are available?

A: The original part is supplied in bulk packaging. All substitute parts are supplied in Tape & Reel (TR) format, standard for surface mount component distribution. Tape & Reel packaging supports automated assembly processes.

Q: Do substitute parts maintain AEC-Q200 automotive qualification?

A: EEE-TG1H330P, EEE-TG1J330UP, EEE-TG1K330UP, and 50THV33M8X10.5 carry AEC-Q200 automotive qualification. EMVH500ARA330MHA0G, EDT336M050A9MAA, EDT336M050S9MAA, and UCJ1H330MCL1GS do not list AEC-Q200 qualification. Select AEC-Q200 qualified parts for automotive applications.

Q: Can the original part be used interchangeably with KEMET EDT336M series?

A: EDT336M050A9MAA and EDT336M050S9MAA maintain 33 µF, 50 V specifications with compatible land size (8.30 mm x 8.30 mm). Physical height is 0.413" (10.50 mm) versus 0.394" (10.00 mm) for the original. Both KEMET parts are active status and ROHS3 compliant. EDT336M050S9MAA includes AEC-Q200 qualification.
