Substitute Part Grouping Explanation

Substitution eligibility is determined by the following criteria:

Electrical Parameters (Critical): Capacitance value (100 µF), voltage rating (160 V minimum), and tolerance (±20%) must match or exceed the main part specifications.

Mechanical Parameters (Critical): Lead spacing (0.197" / 5.00mm), case diameter (0.492" / 12.50mm), and height must be compatible with PCB layout and mounting constraints. Package type must remain radial, can configuration for through-hole mounting.

Thermal & Reliability Parameters (Application-Dependent): Lifetime rating, operating temperature range, and ripple current ratings determine suitability based on circuit requirements. Extended lifetime ratings and higher temperature operation provide design margin but are not mandatory for direct substitution.

Compliance & Regulatory: RoHS3 compliance and REACH status ensure regulatory alignment with existing designs.

Substitute parts are categorized as follows:

Upgrade: Enhanced performance characteristics (extended lifetime, higher temperature rating, or improved ripple current handling) while maintaining identical electrical and mechanical specifications.
Similar: Equivalent electrical and mechanical parameters with minor dimensional variations (lead spacing or height) that may require PCB layout verification.
Parametric Equivalent: Identical core specifications with minor variations in ripple current or ESR characteristics.
Direct: Cross-manufacturer equivalents with matching specifications from alternative suppliers.

Frequently Asked Questions (FAQ)

Q: Can UVR2C101MHD be replaced with UCS2C101MHD?

A: Yes. UCS2C101MHD is a direct upgrade with identical electrical specifications (100 µF, 160 V, ±20%) and mechanical footprint (5.00mm lead spacing, 0.492" diameter). The height difference of 0.020" (1.043" vs 1.063") is negligible for most PCB layouts. UCS2C101MHD offers extended lifetime (10000 Hrs @ 105°C) and higher operating temperature range, making it suitable for designs requiring enhanced reliability.

Q: What is the difference between UVR2C101MHD and URS2C101MHD?

A: Both parts are electrically identical (100 µF, 160 V, ±20%) and share the same lifetime rating (2000 Hrs @ 85°C). The critical difference is mechanical: URS2C101MHD has 7.50mm lead spacing and 18.00mm case diameter, compared to UVR2C101MHD's 5.00mm lead spacing and 12.50mm diameter. URS2C101MHD requires PCB layout modification and is not a direct pin-compatible substitute.

Q: Can I use UCY2D101MHD as a substitute for UVR2C101MHD?

A: Yes, with design margin consideration. UCY2D101MHD is electrically compatible with 100 µF capacitance and ±20% tolerance. The voltage rating is 200 V, providing 25% overvoltage margin compared to the 160 V requirement. Mechanical footprint is identical (5.00mm lead spacing, 0.492" diameter). Height is 1.043" versus 1.063". This upgrade is suitable for applications where enhanced voltage stress margin and extended lifetime (12000 Hrs @ 105°C) are beneficial. REACH Affected status requires compliance verification.

Q: Are Chemi-Con ESMG161ELL101MK25S and ESMQ161ELL101MK25S interchangeable?

A: Yes. Both parts are electrically and mechanically identical: 100 µF, 160 V, ±20% tolerance, 5.00mm lead spacing, 0.492" diameter, and 1.043" height. Both are Active products with ROHS3 compliance. Selection between SMG and SMQ series depends on supplier availability and procurement requirements.

Q: What is the impact of height variation (1.063" vs 1.043")?

A: The 0.020" height difference is typically accommodated within standard PCB clearance tolerances. Verification is required only if the original design has tight vertical constraints (low-profile enclosures, stacked PCBs, or proximity to other components). For most general-purpose applications, this variation is not functionally significant.

Q: Can I substitute UVR2C101MHD with a 200 V rated capacitor?

A: Yes. Parts rated for 200 V (UCY2D101MHD, 200PK100MEFC12.5X25) are suitable substitutes. The higher voltage rating provides design margin and does not compromise circuit function. Capacitance and tolerance remain identical (100 µF, ±20%). Mechanical compatibility must be verified based on specific part dimensions.

Q: What does "Not For New Designs" status mean for UVR2C101MHD?

A: This designation indicates the UVR2C101MHD has been superseded in Nichicon's product lifecycle. New designs should specify Active alternatives such as UCS2C101MHD or UVR2C101MHD1AA. Existing designs using UVR2C101MHD remain supported through available inventory and equivalent substitutes, but long-term availability may be limited.

Q: Are all substitute parts ROHS3 compliant?

A: All listed substitute parts are ROHS3 compliant except where noted. UCY2D101MHD is marked REACH Affected, requiring compliance verification for specific regulatory jurisdictions. Confirm compliance status with your procurement requirements before final selection.
