Substitute Part Grouping Explanation

Substitution eligibility for the UPB2G101MHD is determined by the following critical parameters:

Capacitance: 100 µF (exact match required)
Voltage Rating: 400 V minimum (higher ratings acceptable)
Tolerance: ±20% (matching or tighter tolerance acceptable)
Mounting Type: Through Hole (required for PCB compatibility)
Package Type: Radial, Can (required for mechanical fit)
Lead Spacing: 0.295" (7.50mm) (required for footprint compatibility)
Operating Temperature Range: -25°C ~ 105°C minimum (matching or wider range acceptable)

Substitute parts are grouped into two categories:

Direct Equivalents — Parts meeting all critical parameters with identical or superior electrical performance characteristics.

Similar Alternatives — Parts meeting all critical parameters with variations in secondary characteristics such as case diameter, height, or lifetime rating, suitable for applications where these variations do not impact circuit performance.

Engineering Selection Recommendations

Preferred Direct Equivalents (Active Status)

UPT2G101MHD6 and UPT2G101MHD are Nichicon active production parts meeting all critical parameters. Both are ROHS3 compliant. UPT2G101MHD6 features reduced height (1.299") compared to the original UPB2G101MHD, suitable for space-constrained applications. UPT2G101MHD maintains comparable height (1.457") with slightly reduced case diameter (0.630").

UPT2W101MHD provides 450 V rating, exceeding the original 400 V specification. This part is suitable for applications requiring voltage margin or operating in elevated voltage environments. ROHS3 compliant, active production status.

Alternative Manufacturers

107TXK400M (Cornell Dubilier / Illinois Capacitor) matches all critical parameters with 5000 hour lifetime at 105°C. ROHS3 compliant, active production status. ESR specification provided (3.3157 Ohm @ 120Hz).

Secondary Alternatives

LDQ2G101MERYGA (Nichicon, active) meets all critical parameters but features reduced lifetime (2000 Hrs @ 105°C) and different case dimensions (0.787" Dia x 0.787" Height). Suitable only for applications where reduced lifetime is acceptable.

EEU-EE2G101 (Panasonic, obsolete) provides extended lifetime (10000 Hrs @ 105°C) but is classified as obsolete, limiting long-term procurement viability.

Frequently Asked Questions (FAQ)

Q: Can UPT2G101MHD6 directly replace UPB2G101MHD?

A: Yes. Both parts share identical capacitance (100 µF), voltage rating (400 V), tolerance (±20%), lead spacing (0.295"), and case diameter (0.709"). UPT2G101MHD6 is shorter (1.299" vs 1.634"), which may require PCB layout verification but does not affect electrical compatibility.

Q: What is the difference between UPT2G101MHD and UPT2G101MHD6?

A: Both are Nichicon UPT series parts with identical electrical specifications. UPT2G101MHD6 is packaged in bulk and features height of 1.299". UPT2G101MHD is also bulk packaged with height of 1.457" and slightly smaller case diameter (0.630" vs 0.709"). Both are active production alternatives to the obsolete UPB2G101MHD.

Q: Can UPT2W101MHD be used in place of UPB2G101MHD?

A: Yes, with consideration for voltage rating. UPT2W101MHD is rated 450 V versus the original 400 V specification. This higher rating provides additional voltage margin and is electrically compatible. Physical dimensions match the original part (0.709" Dia, 1.634" Height).

Q: Why is LDQ2G101MERYGA listed as a substitute if it has lower lifetime?

A: LDQ2G101MERYGA meets all critical substitution parameters (capacitance, voltage, tolerance, lead spacing, mounting type). The reduced lifetime (2000 Hrs @ 105°C vs 5000 Hrs) is a secondary characteristic. This part is suitable only for applications where the lower lifetime rating does not impact system reliability requirements.

Q: Is EEU-EE2G101 recommended for new designs?

A: EEU-EE2G101 is classified as obsolete, limiting long-term procurement viability. While it meets all critical parameters and offers extended lifetime (10000 Hrs @ 105°C), active production alternatives such as UPT2G101MHD6 or 107TXK400M are preferred for new designs.

Q: What compliance certifications apply to these substitute parts?

A: All active production substitute parts listed (UPT2G101MHD6, UPT2W101MHD, UPT2G101MHD, 107TXK400M) are ROHS3 compliant and REACH unaffected. EEU-EE2G101 and LDQ2G101MERYGA are also ROHS3 compliant and REACH unaffected.

Q: Does lead spacing remain constant across all substitutes?

A: Yes. All substitute parts maintain 0.295" (7.50mm) lead spacing, ensuring PCB footprint compatibility with the original UPB2G101MHD design.
