Substitute Part Grouping Explanation

Substitution for the UPJ2G100MHD is determined by strict electrical and mechanical compatibility. All substitute parts must maintain the following core parameters:

Capacitance: 10 µF (exact match)
Voltage Rating: 400 V minimum (higher voltage ratings are acceptable)
Tolerance: ±20% (standard tolerance match)
Polarization: Polar (electrolytic type)
Lead Spacing: 0.197" (5.00 mm) for direct PCB compatibility
Case Diameter: 0.492" (12.50 mm) for form factor compatibility
Mounting Type: Through Hole
Package Type: Radial, Can

Substitute parts are grouped into two categories:

Direct Substitutes (Same Electrical & Mechanical Specifications): Parts meeting all core parameters with identical or superior lifetime ratings and thermal performance.

Compatible Alternatives (Voltage Upgrade or Lifetime Variation): Parts with higher voltage ratings (450 V) or different lifetime ratings that maintain electrical and mechanical compatibility within the specified parameter ranges.

Engineering Selection Recommendations

For Direct PCB Replacement (Same Form Factor):

Select UCS2W100MHD as the primary substitute. This part maintains identical lead spacing (0.197" / 5.00 mm) and case diameter (0.492" / 12.50 mm), ensuring direct PCB compatibility. The UCS2W100MHD offers superior performance with a 450 V rating (higher than the original 400 V specification) and 10000-hour lifetime at 105°C, compared to the UPJ2G100MHD's 5000-hour rating. The UCS series is active and recommended for new designs.

For Compact Form Factor Applications:

UCY2G100MPD provides a smaller case diameter (0.394" / 10.00 mm) while maintaining the same lead spacing (0.197" / 5.00 mm). This part is suitable for space-constrained designs and offers 10000-hour lifetime at 105°C with active product status. PCB layout modification is required due to the reduced case diameter.

For Equivalent Lifetime Performance:

UPW2G100MHD matches the original UPJ2G100MHD with 5000-hour lifetime at 105°C and identical electrical specifications (10 µF, 400 V, ±20% tolerance). This part maintains the same lead spacing and case diameter for direct replacement. However, the UPW series is obsolete.

For Active Product Status with Standard Specifications:

UAQ2G100MHD is an active part with 400 V rating and 10 µF capacitance. It provides 2000-hour lifetime at 105°C and maintains identical lead spacing and case diameter for direct PCB replacement. This part is suitable for applications where the reduced lifetime is acceptable.

For Non-Nichicon Alternatives:

EKMG401ELL100MJ20S (Chemi-Con KMG series) is an active alternative from a different manufacturer. It maintains 10 µF, 400 V specifications with identical lead spacing (0.197" / 5.00 mm) but features a smaller case diameter (0.394" / 10.00 mm). This part offers 1000-hour lifetime at 105°C and requires PCB layout modification.

Avoid for New Designs:

Parts with "Not For New Designs" or "Obsolete" status (UVZ2G100MHD, UVY2G100MPD, UPJ2G100MHD, UPM2G100MHD, UPS2G100MHD, UPW2G100MHD) should not be selected for new product development. These are suitable only for legacy system maintenance where exact form factor and performance matching is required.

Frequently Asked Questions (FAQ)

Q: Can I use UCS2W100MHD as a direct replacement for UPJ2G100MHD?

A: Yes. Both parts share identical lead spacing (0.197" / 5.00 mm) and case diameter (0.492" / 12.50 mm), enabling direct PCB replacement without layout modification. The UCS2W100MHD provides superior specifications with 450 V rating and 10000-hour lifetime.

Q: What is the difference between UCS2W100MHD and UCY2G100MPD?

A: Both parts offer 10000-hour lifetime at 105°C and active product status. The primary difference is case diameter: UCS2W100MHD has 0.492" (12.50 mm) diameter for direct replacement of the original part, while UCY2G100MPD has 0.394" (10.00 mm) diameter for compact applications. Lead spacing is identical at 0.197" (5.00 mm) for both.

Q: Why do some substitute parts have different case diameters?

A: Case diameter variation reflects different series designs within Nichicon's product line. Smaller diameter parts (0.394" / 10.00 mm) are designed for space-constrained applications, while larger diameter parts (0.492" / 12.50 mm) maintain the original form factor. Lead spacing remains consistent at 0.197" (5.00 mm) across most alternatives, allowing PCB hole compatibility.

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

A: Parts marked "Not For New Designs" are legacy products that remain available for existing system support but should not be incorporated into new product development. These parts may have limited availability or planned discontinuation.

Q: Can I use URZ2G100MHD as a substitute?

A: URZ2G100MHD is not recommended as a direct replacement. While it maintains 10 µF and 400 V specifications, it has different lead spacing (0.295" / 7.50 mm) and case diameter (0.630" / 16.00 mm), requiring significant PCB layout modification. Additionally, its 1000-hour lifetime is substantially lower than the original 5000-hour rating.

Q: Is EKMG401ELL100MJ20S from Chemi-Con compatible?

A: EKMG401ELL100MJ20S maintains electrical compatibility (10 µF, 400 V) and lead spacing (0.197" / 5.00 mm) but has a smaller case diameter (0.394" / 10.00 mm). PCB layout modification is required. This part is from a different manufacturer and offers 1000-hour lifetime at 105°C.

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

A: Ripple current capacity indicates the maximum AC current the capacitor can handle at specified frequencies. Higher ripple current ratings provide greater thermal margin in high-frequency applications. The UCS2W100MHD offers significantly higher ripple current (350 mA @ 100 kHz) compared to the original UPJ2G100MHD (136 mA @ 10 kHz), making it suitable for demanding power supply applications.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts are ROHS3 compliant, matching the original UPJ2G100MHD's environmental compliance status.
