Substitute Part Grouping Explanation

Substitution of the UPJ2E100MHD1TO is determined by the following critical parameters:

Capacitance Value: Must be 10 µF (exact match required)
Voltage Rating: Must be equal to or greater than 250 V
Tolerance: ±20% (standard for this product category)
Package Type: Radial, can configuration with through-hole mounting
Lead Spacing: 0.197" (5.00 mm) pitch
Case Diameter: 0.492" (12.50 mm)
Operating Temperature Range: -40°C ~ 105°C minimum
Polarization: Polar (electrolytic)

Substitute parts are grouped into two categories:

Direct Equivalents (same voltage rating, 250 V): Parts that maintain identical electrical specifications and physical dimensions.

Upgrade Substitutes (higher voltage ratings, 315 V or 350 V): Parts that exceed the original voltage specification while maintaining all other critical parameters, providing enhanced voltage margin and extended lifetime ratings.

Engineering Selection Recommendations

For Direct Replacement (Same Specifications)

UPM2E100MHD1TO is the direct equivalent to UPJ2E100MHD1TO. Both maintain 10 µF capacitance and 250 V voltage rating. The UPM2E100MHD1TO carries AEC-Q200 automotive qualification and is suitable for automotive applications. Height difference is 0.020" (0.50 mm), which is within typical PCB layout tolerances for through-hole components.

For Voltage Upgrade Applications

UPJ2F100MHD1TO and UPM2F100MHD1TO provide 315 V rating while maintaining 10 µF capacitance and 5000-hour lifetime. These are suitable when circuit design permits higher voltage components or when additional voltage margin is required.

UPW2V100MHD1TO offers the highest voltage rating at 350 V with extended lifetime of 7000 hours at 105°C. This part is recommended for applications requiring maximum reliability and voltage headroom. Height is 0.866" (22.00 mm), requiring verification of PCB clearance.

Compliance Considerations

All substitute parts are ROHS3 compliant. UPM series parts (UPM2E100MHD1TO, UPM2F100MHD1TO) carry AEC-Q200 automotive qualification, making them suitable for automotive-grade applications. UPJ and UPW series parts are general-purpose rated.

Frequently Asked Questions (FAQ)

Q: Can UPM2E100MHD1TO replace UPJ2E100MHD1TO directly?

A: Yes. Both parts have identical electrical specifications (10 µF, 250 V, ±20% tolerance, 5000 Hrs @ 105°C) and the same lead spacing (0.197", 5.00 mm). The height difference of 0.020" (0.50 mm) is negligible for through-hole mounting. UPM2E100MHD1TO includes AEC-Q200 automotive qualification.

Q: What is the difference between 250 V and 315 V rated parts?

A: The voltage rating indicates the maximum continuous voltage the capacitor can withstand. A 315 V part can be used in circuits designed for 250 V operation, providing additional voltage margin and safety headroom. All other electrical parameters (capacitance, tolerance, lifetime) remain identical between 250 V and 315 V versions.

Q: Why does UPW2V100MHD1TO have a longer lifetime (7000 Hrs vs. 5000 Hrs)?

A: The UPW series is designed with enhanced thermal performance and internal construction, resulting in extended operational lifetime at 105°C. This part is suitable for applications requiring maximum reliability over extended service periods.

Q: Are there physical size constraints when substituting with higher voltage parts?

A: Yes. UPJ2E100MHD1TO has a maximum height of 0.846" (21.50 mm). UPM2E100MHD1TO, UPM2F100MHD1TO, and UPW2V100MHD1TO all have a maximum height of 0.866" (22.00 mm). Verify PCB clearance and component spacing before substitution. Lead spacing remains constant at 0.197" (5.00 mm) across all parts.

Q: Can these parts be used in automotive applications?

A: UPM series parts (UPM2E100MHD1TO, UPM2F100MHD1TO) carry AEC-Q200 automotive qualification and are suitable for automotive applications. UPJ and UPW series parts are general-purpose rated and should be evaluated against specific automotive requirements if needed.

Q: What is the significance of the series designation (UPJ, UPM, UPW)?

A: The series designation indicates the product line and performance characteristics. UPJ is a general-purpose series. UPM is an automotive-qualified series with AEC-Q200 certification. UPW is a high-reliability series with extended lifetime ratings. All three series share compatible physical dimensions and electrical parameters for the specified capacitance and voltage combinations.
