Substitute Part Grouping Explanation

Substitute parts for the SH470M250ST are categorized based on the following substitution criteria:

Direct Equivalents (Same Voltage Rating - 250 V): Direct substitutes maintain the same 250 V voltage rating and 47 µF capacitance. These parts are selected when the original voltage specification must be preserved and physical dimensions are compatible. Substitution is valid when lead spacing (0.295" / 7.50 mm), case diameter (0.630" / 16.00 mm), and mounting type (Through Hole, Radial) remain unchanged.

Upgrade Substitutes (Higher Voltage Ratings - 350 V and 400 V): Upgrade substitutes provide higher voltage ratings (350 V or 400 V) while maintaining 47 µF capacitance and identical lead spacing and case diameter. These parts are electrically compatible in circuits designed for 250 V operation, as they provide additional voltage margin. Height variations occur due to higher voltage construction requirements.

Tolerance: ±20% (fixed)
Lead Spacing: 0.295" (7.50 mm) (fixed)

Engineering Selection Recommendations

For Direct 250 V Replacement (Same Voltage Specification):

Select from active manufacturer parts with extended lifetime ratings:

EEU-ED2E470S (Panasonic): 10000 Hrs @ 105°C, compact height 0.787" (20.00 mm), ROHS3 compliant, active status
EEU-EE2E470S (Panasonic): 10000 Hrs @ 105°C, height 0.866" (22.00 mm), ROHS3 compliant, active status

Both parts provide 5× to 10× lifetime improvement over the original SH470M250ST specification. Physical dimensions remain compatible with existing PCB layouts due to maintained lead spacing and case diameter.

For Voltage Margin Enhancement (350 V or 400 V Rating):

When circuit design permits higher voltage ratings:

EEU-ED2V470 (Panasonic): 350 V, 10000 Hrs @ 105°C, height 0.984" (25.00 mm), matches original height, ROHS3 compliant, active status
EKXG401ELL470ML25S (Chemi-Con): 400 V, 10000 Hrs @ 105°C, height 0.984" (25.00 mm), matches original height, ROHS3 compliant, active status, highest inventory availability

Compliance Considerations:

All recommended substitutes are ROHS3 compliant and carry REACH Unaffected or REACH Compliant status. All parts maintain EAR99 ECCN classification and 8532.22.0020 HTSUS code, ensuring regulatory consistency with the original component.

Frequently Asked Questions (FAQ)

Q: Can EEU-ED2E470S replace SH470M250ST directly in existing designs?

A: Yes. EEU-ED2E470S maintains identical capacitance (47 µF), voltage rating (250 V), tolerance (±20%), lead spacing (0.295" / 7.50 mm), case diameter (0.630" / 16.00 mm), and through-hole radial mounting. Height is reduced from 0.984" to 0.787", which is compatible with standard PCB layouts. Lifetime is extended from 2000 Hrs to 10000 Hrs @ 105°C.

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

A: Direct equivalents maintain the 250 V voltage rating specified for the original part. Upgrade substitutes provide 350 V or 400 V ratings, offering additional voltage margin in the circuit. Both categories maintain identical capacitance, tolerance, lead spacing, and case diameter. Upgrade substitutes are electrically compatible in 250 V circuits and provide enhanced reliability through higher voltage ratings.

Q: Are height differences between substitute parts critical for PCB compatibility?

A: Height variations occur primarily in direct 250 V equivalents (ranging from 0.787" to 0.866") and upgrade parts (0.984" to 1.063"). Lead spacing and case diameter remain constant at 0.295" (7.50 mm) and 0.630" (16.00 mm) respectively. Verify PCB clearance above the component location. Upgrade parts with 350 V or 400 V ratings at 0.984" height match the original SH470M250ST height exactly.

Q: Why are some substitute parts listed as obsolete?

A: UCA2E470MHD6 (Nichicon) and UPW2E470MHD (Nichicon) are classified as obsolete but remain in stock. Active manufacturer parts from Panasonic (EEU series) and Chemi-Con (EKXG series) are recommended for new designs to ensure long-term supply continuity and manufacturer support.

Q: What is the significance of lifetime rating differences?

A: The original SH470M250ST specifies 2000 Hrs @ 105°C. Substitute parts offer 5000 Hrs (EEU-EB2E470S), 8000 Hrs (UPW2E470MHD), 10000 Hrs (EEU-ED2E470S, EEU-EE2E470S, EEU-ED2V470, EEU-ED2G470, EKXG401ELL470ML25S), or 12000 Hrs (UCA2E470MHD6). Extended lifetime ratings indicate improved thermal stability and reduced degradation in high-temperature applications.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All substitute parts listed are ROHS3 compliant. The original SH470M250ST is also ROHS3 compliant. This ensures regulatory consistency across all recommended alternatives.

Q: Which substitute offers the highest ripple current capability?

A: EKXG401ELL470ML25S (Chemi-Con) provides the highest ripple current specifications: 470 mA @ 120 Hz and 1.175 A @ 100 kHz. This part is suitable for applications requiring enhanced ripple current handling at higher frequencies.

Q: Can I use a 350 V or 400 V rated part in a 250 V circuit?

A: Yes. Higher voltage-rated capacitors are electrically compatible in lower voltage circuits. The 350 V and 400 V rated substitutes (EEU-EB2V470, EEU-ED2V470, EEU-ED2G470, EKXG401ELL470ML25S) operate safely in 250 V applications and provide additional voltage margin for circuit protection.
