UPJ1V331MHD6TO Equivalent & Substitute Parts

Part Overview

The UPJ1V331MHD6TO is a 330 µF, 35 V aluminum electrolytic capacitor in radial configuration manufactured by Nichicon. This component is classified as "Not For New Designs," indicating it has reached end-of-life status. The part is designed for general-purpose applications requiring through-hole mounting with a 5000-hour lifetime rating at 105°C operating temperature. Due to its discontinued design status, identifying functionally equivalent substitute parts is essential for ongoing maintenance, repair, and legacy system support.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the UPJ1V331MHD6TO are identified based on strict electrical and mechanical compatibility criteria. The primary substitution parameters are:

• Capacitance value: 330 µF (exact match required)
• Voltage rating: 35 V (exact match required)
• Tolerance: ±20% (exact match required)
• Lead spacing: 0.197" (5.00mm) (exact match required)
• Package configuration: Radial, Can through-hole (exact match required)
• Polarization: Polar (exact match required)

Two direct substitutes are identified within the Nichicon product line:

1. UPJ1V331MHD6 — Same electrical specifications as the main part, differing only in packaging format (Bulk vs. Cut Tape). This part maintains identical electrical performance and physical dimensions.

2. UPM1V331MHD6TO — Shares identical electrical specifications and packaging format (Cut Tape). This part is qualified to AEC-Q200 automotive standard and is suitable for automotive applications. Physical dimensions are nearly identical with a maximum seated height of 0.669" (17.00mm) compared to 0.650" (16.50mm) for the main part.

Parameter Comparison

Engineering Selection Recommendations

UPJ1V331MHD6 is the direct electrical equivalent to UPJ1V331MHD6TO. The only difference is packaging format: this part is supplied in Bulk rather than Cut Tape. Selection of this substitute is appropriate when packaging format does not constrain procurement or assembly processes. Both parts carry identical ROHS3 compliance and product status designation.

UPM1V331MHD6TO is suitable for applications requiring automotive-grade qualification. This part carries AEC-Q200 certification and is appropriate for automotive and mission-critical applications. The UPM series exhibits lower impedance (65 mOhms vs. 100 mOhms), which may provide performance benefits in high-ripple-current applications. The maximum seated height is 0.019" (0.50mm) greater than the main part; verify PCB layout clearance before substitution. This part is available in Cut Tape packaging matching the main part format.

Both substitutes maintain identical electrical specifications, temperature ratings, and compliance certifications. Selection between them depends on application requirements and packaging constraints.

Frequently Asked Questions (FAQ)

Q: Can UPJ1V331MHD6 be used as a direct replacement for UPJ1V331MHD6TO?

A: Yes. Both parts are electrically and mechanically identical. The difference is packaging format only: UPJ1V331MHD6 is supplied in Bulk, while UPJ1V331MHD6TO is supplied in Cut Tape. Substitution is valid when packaging format does not affect procurement or assembly workflow.

Q: What is the difference between UPJ and UPM series capacitors?

A: The UPM series carries AEC-Q200 automotive qualification and exhibits lower impedance (65 mOhms vs. 100 mOhms). The UPJ series is general-purpose. Both share identical capacitance, voltage, tolerance, and temperature ratings. UPM is appropriate for automotive applications; UPJ is suitable for general industrial and consumer applications.

Q: Does the 0.019" height difference between UPJ1V331MHD6TO and UPM1V331MHD6TO affect PCB compatibility?

A: The UPM1V331MHD6TO has a maximum seated height of 0.669" (17.00mm) compared to 0.650" (16.50mm) for UPJ1V331MHD6TO. Verify available vertical clearance on the PCB before substitution. In most applications, this difference is negligible; however, space-constrained designs may require layout verification.

Q: Are all three parts RoHS compliant?

A: Yes. UPJ1V331MHD6TO, UPJ1V331MHD6, and UPM1V331MHD6TO are all ROHS3 compliant.

Q: Can these capacitors be used in new designs?

A: All three parts carry "Not For New Designs" status. They are suitable for replacement, repair, and legacy system support only. For new designs, consult current Nichicon product offerings.

Q: What is the significance of the lower impedance in UPM1V331MHD6TO?

A: Lower impedance (65 mOhms vs. 100 mOhms) reduces voltage drop across the capacitor at high ripple currents. This characteristic is beneficial in power supply filtering and high-frequency applications. The UPM series is optimized for automotive environments where thermal and electrical stress is elevated.
