Substitute Part Grouping Explanation

Substitution eligibility for the UPM1K680MHD6TO is determined by the following critical parameters: capacitance value (68 µF), tolerance (±20%), polarization (polar), package type (radial, can), lead spacing (5.00mm), and mounting type (through hole). Voltage rating may be equal or higher than the original specification. Operating temperature range and lifetime at rated temperature must meet or exceed the original part requirements.

The substitute parts are grouped into two categories:

Direct Equivalent: UPJ1K680MHD6TO maintains identical electrical specifications (68 µF, 80 V, ±20% tolerance) with matching physical dimensions and lead spacing. This part differs in application classification (general purpose versus automotive) and ripple current performance.

Upgraded Substitutes: UPJ2A680MHD6TO and UPM2A680MHD6TO provide higher voltage ratings (100 V) while maintaining all other critical parameters. These parts are pin-compatible and functionally interchangeable in circuits designed for 80 V operation.

Engineering Selection Recommendations

For Automotive Applications: UPM2A680MHD6TO is the preferred substitute. It maintains AEC-Q200 automotive qualification, matches the original series designation (UPM), and provides upgraded voltage rating (100 V) with improved ripple current handling (380 mA @ 120 Hz). The identical seated height (17.00mm) ensures PCB layout compatibility.

For General Purpose Applications: UPJ1K680MHD6TO provides direct electrical equivalence with identical voltage and capacitance specifications. This part is suitable for non-automotive designs where AEC-Q200 compliance is not required.

For Voltage Margin Enhancement: UPJ2A680MHD6TO offers 100 V rating in the general purpose series. This part is appropriate when additional voltage headroom is needed without automotive qualification requirements.

All substitute parts maintain ROHS3 compliance and identical lead spacing (5.00mm), ensuring direct PCB footprint compatibility.

Frequently Asked Questions (FAQ)

Q: Can UPJ1K680MHD6TO replace UPM1K680MHD6TO in automotive circuits?

A: UPJ1K680MHD6TO is electrically equivalent but lacks AEC-Q200 automotive qualification. Use only in non-automotive applications or where automotive certification is not required.

Q: What is the advantage of using UPM2A680MHD6TO or UPJ2A680MHD6TO?

A: Both parts provide 100 V rating versus the original 80 V specification. This higher voltage rating reduces stress on the capacitor in circuits operating near maximum voltage limits. UPM2A680MHD6TO additionally maintains automotive qualification.

Q: Are the substitute parts physically compatible with the original PCB layout?

A: All substitute parts share identical lead spacing (5.00mm) and package type (radial, can). UPJ1K680MHD6TO and UPJ2A680MHD6TO have slightly reduced seated height (16.50mm versus 17.00mm), which does not affect PCB compatibility. UPM2A680MHD6TO matches the original height (17.00mm) exactly.

Q: Do all substitute parts meet the same temperature and lifetime specifications?

A: Yes. All substitute parts maintain the -55°C to 105°C operating temperature range and 5000-hour lifetime at 105°C rating.

Q: What is the impedance difference between the 80 V and 100 V rated parts?

A: The 100 V rated parts (UPJ2A680MHD6TO and UPM2A680MHD6TO) have lower impedance (230 mOhms) compared to the 80 V rated parts (310 mOhms). Lower impedance provides better high-frequency ripple current performance.
