UPJ1C122MHD1TO Equivalent & Substitute Parts

Part Overview

The UPJ1C122MHD1TO is a 1200 µF, 16 V aluminum electrolytic capacitor in radial configuration manufactured by Nichicon. This component is rated for 5000 hours at 105°C and is classified as Not For New Designs. Due to its obsolescence status, identifying equivalent and substitute parts is necessary for ongoing maintenance, repair, and legacy system support. Suitable alternatives must maintain the same capacitance value, tolerance, and physical form factor while meeting or exceeding the voltage and thermal specifications of the original component.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the UPJ1C122MHD1TO is determined by the following critical parameters:

• Capacitance Value: Must be 1200 µF
• Tolerance: Must be ±20%
• Voltage Rating: Must be equal to or greater than 16 V
• Physical Form Factor: Lead spacing of 0.197" (5.00mm), radial can package, through-hole mounting
• Operating Temperature Range: Must support -55°C ~ 105°C
• Polarization: Polar configuration required

Substitute parts are grouped into two categories:

Parametric Equivalents maintain identical electrical specifications (1200 µF, 16 V, ±20%) with the same physical footprint and thermal rating.

Upgrade Substitutes provide enhanced voltage ratings (25 V) or extended thermal lifetime (10000 Hrs @ 105°C), offering improved performance margins while maintaining mechanical compatibility and the same capacitance value.

Parameter Comparison

Engineering Selection Recommendations

UPA1E122MHD1TO (Nichicon) is the primary upgrade substitute. It maintains identical physical dimensions and lead spacing to the original UPJ1C122MHD1TO while providing a higher voltage rating of 25 V. This part carries Active product status and offers lower impedance (29 mOhms versus 60 mOhms), resulting in improved performance characteristics. ROHS3 compliance is maintained.

UPM1C122MHD1TO (Nichicon) is a parametric equivalent with identical voltage and capacitance specifications. It is qualified to AEC-Q200 automotive standards and maintains the same physical footprint. This part is suitable for applications requiring automotive-grade reliability, though it carries Not For New Designs status.

860080478021 (Würth Elektronik) provides a 25 V upgrade with Active product status and the lowest impedance (25 mOhms) among all substitutes. Minor dimensional variations exist: the can diameter is 0.512" (13.00mm) versus 0.492" (12.50mm), and height is 0.846" (21.50mm) versus 0.866" (22.00mm). Lead spacing remains compatible at 0.197" (5.00mm). Packaging is supplied as Tape & Box rather than Cut Tape.

860160478029 (Würth Elektronik) offers the extended thermal lifetime of 10000 hours at 105°C with 25 V rating and Active product status. Dimensional variations match the 860080478021 part. This option is suitable for applications requiring maximum thermal endurance.

Frequently Asked Questions (FAQ)

Q: Can UPA1E122MHD1TO directly replace UPJ1C122MHD1TO?

A: Yes. Both parts share identical capacitance (1200 µF), tolerance (±20%), physical dimensions (0.492" diameter, 0.866" height), and lead spacing (0.197"). The UPA1E122MHD1TO provides a higher voltage rating (25 V versus 16 V), which is compatible with circuits designed for 16 V operation.

Q: What is the difference between the Nichicon and Würth Elektronik substitutes?

A: Nichicon substitutes (UPA1E122MHD1TO, UPM1C122MHD1TO) maintain the exact original dimensions. Würth Elektronik parts (860080478021, 860160478029) have slightly larger can diameters (0.512" versus 0.492") and marginally reduced heights (0.846" versus 0.866"), though lead spacing remains identical. Both manufacturers provide ROHS3 compliance.

Q: Which substitute offers the best performance?

A: Selection depends on application requirements. UPA1E122MHD1TO provides the lowest impedance (29 mOhms) among Nichicon options with Active status. 860080478021 offers the lowest impedance overall (25 mOhms) with Active status. 860160478029 provides extended thermal lifetime (10000 Hrs @ 105°C) for demanding thermal environments.

Q: Are there packaging differences between substitutes?

A: UPJ1C122MHD1TO, UPA1E122MHD1TO, and UPM1C122MHD1TO are supplied in Cut Tape (CT) packaging. 860080478021 is supplied in Tape & Box (TB) packaging. 860160478029 is supplied in Cut Tape (CT). Verify packaging compatibility with your procurement and assembly processes.

Q: Can I use a 25 V rated capacitor in a 16 V circuit?

A: Yes. A higher voltage rating provides additional safety margin and does not affect circuit operation. The capacitance value and tolerance remain the same, ensuring equivalent electrical behavior.

Q: What is the significance of the "Not For New Designs" status?

A: This designation indicates the original UPJ1C122MHD1TO and UPM1C122MHD1TO are in mature or declining production phases. For new designs, Active-status alternatives such as UPA1E122MHD1TO, 860080478021, or 860160478029 are recommended to ensure long-term availability and supply chain stability.
