Tolerance: ±20% (exact match required)
Lead Spacing: 0.295" (7.50 mm) (exact match required)
Size / Dimension: 0.630" Dia (16.00 mm) (exact match required)
Mounting Type: Through Hole (exact match required)
Package / Case: Radial, Can (exact match required)

Parameters Allowing Variation:

Voltage - Rated: May be equal to or greater than 6.3 V
ESR: Lower values are acceptable
Lifetime @ Temperature: Equal to or greater than 2000 Hrs @ 105°C
Operating Temperature Range: May be extended (lower minimum or higher maximum acceptable)
RoHS Status: ROHS3 Compliant required

Substitute parts are grouped into two categories:

Upgrade Substitutes: Parts with rated voltage greater than 6.3 V (SEK472M010ST, EEU-FC1A472) or extended lifetime specifications (UPW0J472MHD). These parts maintain or exceed all critical electrical and mechanical parameters.

Similar Substitutes: Parts with different voltage ratings (478CKH016M at 16 V) that share identical mechanical dimensions and lead spacing but require voltage compatibility verification in the application circuit.

Engineering Selection Recommendations

For Direct Replacement (Preferred):

SEK472M010ST (Cornell Dubilier Electronics) is the primary upgrade substitute. This part maintains identical mechanical dimensions, lead spacing, and package configuration while providing higher rated voltage (10 V vs. 6.3 V) and lower ESR (80 mOhm vs. 90 mOhm). The SEK series is in active production status, ensuring long-term availability. ROHS3 compliance is maintained.

For Extended Lifetime Applications:

EEU-FC1A472 (Panasonic Electronic Components) offers 5000 Hrs @ 105°C lifetime, exceeding the original 2000 Hrs specification. This part carries AEC-Q200 automotive rating and is suitable for applications requiring enhanced reliability. Rated voltage is 10 V. This part is in active production status.

UPW0J472MHD (Nichicon) provides the longest lifetime at 8000 Hrs @ 105°C with extended operating temperature range (-55°C ~ 105°C). However, this part is classified as "Not For New Designs," limiting its use to legacy system support only.

For Voltage-Rated Applications:

478CKH016M (Cornell Dubilier / Illinois Capacitor) is suitable only when circuit design permits 16 V rated voltage. This part is in active production. Note: Height dimension is 1.240" (31.50 mm), exceeding the original 0.984" (25.00 mm). Physical space constraints must be verified before selection.

Compliance Verification:

All substitute parts maintain ROHS3 compliance. EEU-FC1A472 and UPW0J472MHD carry REACH Unaffected status. Selection should align with end-application regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can SEK472M010ST be used as a direct replacement for SH472M6R3ST?

A: Yes. SEK472M010ST is electrically and mechanically compatible. Both parts share identical capacitance (4700 µF), tolerance (±20%), lead spacing (0.295" / 7.50 mm), diameter (0.630" / 16.00 mm), height (0.984" / 25.00 mm), and mounting type (Through Hole, Radial Can). The higher voltage rating (10 V vs. 6.3 V) and lower ESR (80 mOhm vs. 90 mOhm) are advantageous. SEK472M010ST is in active production, ensuring supply availability.

Q: What is the difference between upgrade substitutes and similar substitutes?

A: Upgrade substitutes (SEK472M010ST, EEU-FC1A472, UPW0J472MHD) maintain or exceed all electrical and mechanical parameters of the original part.

A: No. UPW0J472MHD is classified as "Not For New Designs." This part is suitable only for legacy system maintenance and repair. For new designs, select SEK472M010ST or EEU-FC1A472.

Q: What are the key parameters that determine substitution compatibility?

A: Substitution compatibility is determined by: capacitance (4700 µF), tolerance (±20%), lead spacing (0.295" / 7.50 mm), diameter (0.630" / 16.00 mm), height (0.984" / 25.00 mm), mounting type (Through Hole), and package type (Radial, Can). Rated voltage may be equal to or greater than 6.3 V. ESR and lifetime may be equal to or better than original specifications.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All substitute parts listed (SEK472M010ST, EEU-FC1A472, UPW0J472MHD, 478CKH016M) are ROHS3 compliant, matching the original SH472M6R3ST compliance status.

Q: What is the inventory status of substitute parts?
