UVR2C101MHA Equivalent & Substitute Parts

Part Overview

The UVR2C101MHA is a 100 µF, 160 V aluminum electrolytic capacitor in radial, can package manufactured by Nichicon. This part is classified as obsolete and operates across a temperature range of -40°C to 85°C with a rated lifetime of 2000 hours at 85°C. Due to its obsolete status, equivalent and upgraded substitute parts are necessary for ongoing design support and procurement continuity. Substitute options include direct equivalents from the same manufacturer, cross-manufacturer alternatives with identical electrical specifications, and upgraded variants offering enhanced performance characteristics such as extended lifetime or higher voltage ratings.

Substitute Part Grouping Explanation

Substitution eligibility for the UVR2C101MHA is determined by the following core parameters: capacitance value (100 µF), voltage rating (160 V or higher), tolerance (±20%), package type (radial, can), lead spacing (5.00 mm), physical dimensions (12.50 mm diameter), and mounting type (through hole). Parts are grouped into three categories:

Direct Equivalents maintain identical electrical and mechanical specifications, differing only in product status or packaging format. These include UVR2C101MHD (Nichicon, same series, bulk packaging), UVR2C101MHD1AA (Nichicon, active status), ESMG161ELL101MK25S (Chemi-Con SMG series), and ESMQ161ELL101MK25S (Chemi-Con SMQ series). All direct equivalents share 100 µF capacitance, 160 V rating, 2000 hour lifetime at 85°C, and identical physical dimensions.

Upgraded Equivalents maintain core electrical specifications (100 µF, 160 V) and physical compatibility while offering enhanced performance. UCS2C101MHD (Nichicon UCS series) extends lifetime to 10,000 hours at 105°C and increases operating temperature to 105°C. 160PX100MEFC12.5X25 (Rubycon PX series) provides 2000 hour lifetime at 105°C with extended temperature range. EKMQ161ELL101MK25S (Chemi-Con KMQ series) offers 2000 hour lifetime at 105°C. B43851F1107M000 (EPCOS-TDK) delivers 3000 hour lifetime at 105°C with specified ESR of 2.3 Ohm @ 120 Hz.

Higher Voltage Alternatives maintain 100 µF capacitance and physical compatibility while increasing voltage rating to 200 V. UCY2D101MHD (Nichicon UCY series) and 200PK100MEFC12.5X25 (Rubycon PK series) both provide 200 V rating with enhanced lifetime specifications.

Engineering Selection Recommendations

For direct replacement of UVR2C101MHA in existing designs, UVR2C101MHD1AA (Nichicon, active status) provides identical electrical and mechanical specifications with current product availability. This part maintains the same 100 µF capacitance, 160 V rating, 2000 hour lifetime at 85°C, and physical dimensions, ensuring drop-in compatibility.

For new designs or applications requiring enhanced reliability, UCS2C101MHD (Nichicon UCS series, active status, ROHS3 compliant) is recommended. This part maintains electrical compatibility while extending lifetime to 10,000 hours at 105°C and expanding operating temperature range to 105°C. The slightly reduced height (26.50 mm vs. 27.00 mm) remains within standard through-hole PCB tolerances.

For applications requiring higher voltage margin, UCY2D101MHD (Nichicon UCY series, active status, ROHS3 compliant) provides 200 V rating with 12,000 hour lifetime at 105°C. Physical dimensions remain compatible with original footprint.

Cross-manufacturer alternatives include ESMG161ELL101MK25S and ESMQ161ELL101MK25S (Chemi-Con, active status, ROHS3 compliant), both offering identical 160 V specifications with active product status. EKMQ161ELL101MK25S (Chemi-Con KMQ series) extends operating temperature to 105°C while maintaining 160 V rating.

For applications with extended temperature operation, 160PX100MEFC12.5X25 (Rubycon PX series, active status, ROHS3 compliant) provides 2000 hour lifetime at 105°C with identical physical dimensions to the original part.

All recommended substitutes are ROHS3 compliant and carry active product status, ensuring long-term availability and regulatory compliance.

Frequently Asked Questions (FAQ)

Q: Can UVR2C101MHD be used as a direct replacement for UVR2C101MHA?

A: UVR2C101MHD is electrically and mechanically equivalent to UVR2C101MHA, maintaining identical 100 µF capacitance, 160 V rating, 2000 hour lifetime at 85°C, and physical dimensions. However, UVR2C101MHD carries "Not For New Designs" status. For new designs, UVR2C101MHD1AA (active status) is preferred.

Q: What is the difference between direct equivalents and upgraded equivalents?

A: Direct equivalents (UVR2C101MHD, UVR2C101MHD1AA, ESMG161ELL101MK25S, ESMQ161ELL101MK25S) maintain identical electrical specifications and lifetime ratings. Upgraded equivalents (UCS2C101MHD, 160PX100MEFC12.5X25, EKMQ161ELL101MK25S, B43851F1107M000) extend lifetime or operating temperature while preserving 100 µF capacitance and 160 V rating.

Q: Are there physical dimension differences between substitute parts?

A: Most substitutes maintain the 12.50 mm diameter and 5.00 mm lead spacing. Height varies slightly: original and some substitutes measure 27.00 mm, while others measure 26.50 mm. This 0.50 mm difference remains within standard through-hole PCB tolerance and does not affect mechanical compatibility.

Q: Can I use a 200 V rated capacitor in place of the 160 V original?

A: Yes. UCY2D101MHD and 200PK100MEFC12.5X25 both provide 200 V rating with identical 100 µF capacitance and physical compatibility. Higher voltage rating provides additional safety margin in the circuit without affecting performance at 160 V operation.

Q: Which substitute offers the longest operational lifetime?

A: UCY2D101MHD (Nichicon UCY series) provides the longest specified lifetime at 12,000 hours at 105°C. UCS2C101MHD offers 10,000 hours at 105°C. B43851F1107M000 (EPCOS-TDK) provides 3000 hours at 105°C with specified ESR characteristics.

Q: Are all substitute parts RoHS compliant?

A: All recommended active-status substitutes are ROHS3 compliant. The original UVR2C101MHA is RoHS non-compliant. UVR2C101MHD carries ROHS3 compliance despite "Not For New Designs" status.

Q: What is the significance of product status (Active, Not For New Designs, Obsolete)?

A: Active status indicates current manufacturing and long-term availability. "Not For New Designs" indicates the part is available but not recommended for new circuit designs. Obsolete status indicates the part is no longer manufactured. For procurement continuity, active-status parts are preferred.
