Engineering Selection Recommendations

Direct Equivalent Selection:

The EEU-TA1H220 (Panasonic) and UBT1H220MPD8 (Nichicon) are direct electrical equivalents to the 226HSM050M. Both parts maintain identical capacitance (22 µF), voltage rating (50 V), tolerance (±20%), and lifetime specifications (2000 Hrs @ 125°C). Both manufacturers are active, ensuring long-term supply availability.

The EEU-TA1H220 features a slightly lower seated height (0.492" vs. 0.512"), which may provide a minor advantage in space-constrained applications. The UBT1H220MPD8 has a higher seated height (0.531"), which requires verification against PCB layout constraints.

Upgrade Part Selection:

The 50RX3022M8X11.5 (Rubycon) provides an enhanced alternative with identical electrical specifications at 50 V but with improved thermal performance (2000 Hrs @ 130°C vs. 125°C). This part maintains the same seated height as the original (0.512") and includes AEC-Q200 automotive qualification.

The 100RX3022M8X11.5 (Rubycon) offers higher voltage capability (100 V) with enhanced thermal performance (2000 Hrs @ 130°C). This upgrade is suitable for applications requiring voltage margin or operating in elevated temperature environments.

The EEU-TA1J220 and UBT1J220MPD8 provide 63 V rated alternatives, and the UBT1K220MPD8 provides 80 V rated alternative. These upgrades are suitable for circuits requiring higher voltage margins.

Compliance and Certification:

All active substitute parts are RoHS3 compliant. The Rubycon parts (100RX3022M8X11.5 and 50RX3022M8X11.5) carry AEC-Q200 automotive qualification. Nichicon parts (UBT series) are marked as REACH Affected. Panasonic parts (EEU-TA series) are REACH Unaffected.

Lead Spacing Consideration:

The EEU-TA1H220B differs from the main part only in lead spacing (0.197" vs. 0.138"). This part is suitable only for applications with PCB footprints designed for 5.00mm lead spacing.

Frequently Asked Questions (FAQ)

Q: Can the EEU-TA1H220 directly replace the 226HSM050M without PCB modification?

A: The EEU-TA1H220 maintains identical lead spacing (0.138" / 3.50mm), size (0.315" Dia / 8.00mm), and mounting type (Through Hole, Radial Can). The seated height is 0.492" compared to 0.512" for the original part. Direct substitution is possible if the PCB footprint accommodates the slightly lower height. Verify clearance above the capacitor location.

Q: What is the difference between direct equivalents and upgrade parts?

A: Direct equivalents (EEU-TA1H220, UBT1H220MPD8) maintain identical electrical specifications including voltage rating (50 V) and thermal performance (2000 Hrs @ 125°C). Upgrade parts provide higher voltage ratings (63 V, 80 V, 100 V) or enhanced thermal performance (2000 Hrs @ 130°C), making them suitable for applications requiring additional design margin or operation in elevated temperature environments.

Q: Are all substitute parts through-hole radial can packages?

A: Yes. All substitute parts listed maintain the through-hole radial can package format. The only exception is EEU-TA1H220B, which differs in lead spacing (0.197" vs. 0.138") and packaging format (Cut Tape vs. Bulk). This part requires a different PCB footprint.

Q: Which substitute part has the lowest ESR?

A: The 50RX3022M8X11.5 (Rubycon) has an impedance of 35 mOhms, which is significantly lower than the original part's ESR of 7.536 Ohm @ 120Hz. This lower impedance provides improved ripple current handling and reduced voltage drop under transient conditions.

Q: Can I use a 100 V rated capacitor in a 50 V circuit?

A: Yes. The 100RX3022M8X11.5 (100 V rated) is electrically compatible with circuits designed for 50 V operation. Higher voltage-rated capacitors are backward compatible and provide additional voltage margin. Verify that the physical dimensions (0.531" height) fit within the available PCB space.

Q: What is the difference between Panasonic EEU-TA1H220 and EEU-TA1H220B?

A: Both parts are electrically identical 22 µF, 50 V capacitors from Panasonic's TA series. The primary difference is lead spacing: EEU-TA1H220 has 0.138" (3.50mm) spacing, while EEU-TA1H220B has 0.197" (5.00mm) spacing. Additionally, EEU-TA1H220B is supplied in Cut Tape (CT) packaging versus Bulk for the standard version. Select based on PCB footprint requirements.

Q: Are Nichicon UBT series parts suitable for automotive applications?

A: Yes. The Nichicon UBT series (UBT1H220MPD8, UBT1J220MPD8, UBT1K220MPD8) are specified for automotive applications. However, note that these parts are marked as REACH Affected, which may require compliance verification for specific end-use applications.

Q: Which substitute offers the best thermal performance?

A: The Rubycon RX30 series parts (100RX3022M8X11.5 and 50RX3022M8X11.5) offer enhanced thermal performance with 2000-hour lifetime at 130°C, compared to 125°C for other alternatives. The 50RX3022M8X11.5 maintains the same 50 V rating and 0.512" height as the original part while providing this thermal upgrade.
