Substitute Part Grouping Explanation

Substitution of the SH470M6R3ST is determined by the following critical parameters:

Direct Equivalence Criteria:

Capacitance: 47 µF (exact match required)
Tolerance: ±20% (exact match required)
Voltage Rating: 6.3 V minimum (equal or higher voltage acceptable)
Lead Spacing: 0.079" (2.00 mm) (exact match required)
Case Diameter: 0.197" (5.00 mm) (exact match required)
Mounting Type: Through Hole (exact match required)
Package Type: Radial, Can (exact match required)
Operating Temperature Range: -40°C to 105°C minimum (equal or wider range acceptable)
Lifetime @ 105°C: 2000 Hrs minimum (equal or greater acceptable)

Substitution Categories:

Category 1: Direct Voltage Equivalents (6.3 V) Parts with identical voltage rating maintain the same electrical performance envelope and are suitable for direct replacement without circuit modification.

Category 2: Voltage Upgrades (10 V, 25 V, 35 V) Parts with higher voltage ratings are electrically compatible in circuits designed for 6.3 V operation. Higher voltage ratings provide additional safety margin and are acceptable substitutes when physical dimensions and mounting remain identical.

Category 3: Similar Voltage Alternatives (25 V, 35 V) Parts with significantly higher voltage ratings are suitable for applications where voltage headroom is beneficial, provided all mechanical and electrical parameters align with the original specification.

Engineering Selection Recommendations

For Direct Replacement (Same Voltage, 6.3 V):

UPW0J470MDD (Nichicon) is the closest direct equivalent to SH470M6R3ST. Both parts share identical capacitance, voltage rating, tolerance, lead spacing, case diameter, and height. UPW0J470MDD extends the operating temperature range to -55°C, providing enhanced low-temperature performance. However, UPW0J470MDD is also classified as obsolete, limiting long-term procurement viability.

For Active Product Substitution (Voltage Upgrade to 10 V):

SEK470M010ST (Cornell Dubilier) is an active product offering from the same manufacturer as the original part. It maintains 47 µF capacitance, ±20% tolerance, identical lead spacing and case diameter, and 2000-hour lifetime at 105°C. The voltage upgrade from 6.3 V to 10 V is electrically compatible with circuits designed for the original 6.3 V rating. Height increases from 0.433" to 0.512", requiring verification of available board space. Operating temperature range extends to -55°C.

For Higher Voltage Margin (25 V Rating):

UPW1E470MDD (Nichicon) and 517D476M025JA6AE3 (Vishay Sprague) both provide 25 V ratings with identical mechanical dimensions to the original part (0.433" height). Both maintain 47 µF capacitance, ±20% tolerance, and 2000-hour lifetime at 105°C. These parts are obsolete but offer significant voltage headroom for applications requiring additional safety margin.

For Active Long-Term Availability (25 V Rating):

EEU-EB1E470S (Panasonic Electronic Components) is an active product with 47 µF capacitance, 25 V rating, ±20% tolerance, and extended 5000-hour lifetime at 105°C. Height is 0.472" (within 0.039" of original). This part provides the longest operational life rating and active product status for sustained procurement.

EKZE250ELL470ME11D (Chemi-Con) is an active product with 47 µF capacitance, 25 V rating, ±20% tolerance, and 2000-hour lifetime at 105°C. Height is 0.492" (within 0.059" of original). This part offers active status with established supply chain availability.

For Maximum Voltage Headroom (35 V Rating):

476CKE035M (Cornell Dubilier / Illinois Capacitor) is an active product with 47 µF capacitance, 35 V rating, ±20% tolerance, and 2000-hour lifetime at 105°C. Height is 0.492" (within 0.059" of original). This part provides the highest voltage rating among available substitutes and maintains active product status.

RoHS3 Compliance:

All listed substitute parts are ROHS3 compliant, matching the original part's environmental certification status.

Frequently Asked Questions (FAQ)

Q: Can I use a 10 V rated capacitor in place of the 6.3 V SH470M6R3ST?

A: Yes. A 10 V rated capacitor is electrically compatible in circuits designed for 6.3 V operation. The higher voltage rating provides additional safety margin and does not degrade circuit performance. All mechanical parameters (lead spacing, case diameter, mounting type) must remain identical.

Q: What is the difference between direct equivalents and voltage upgrades?

A: Direct equivalents (such as UPW0J470MDD) maintain the same 6.3 V voltage rating as the original part. Voltage upgrades (such as SEK470M010ST or UPW1E470MDD) provide higher voltage ratings (10 V, 25 V, or 35 V) while maintaining identical capacitance and tolerance. Both categories are mechanically and electrically compatible substitutes.

Q: Does the height difference between substitute parts affect compatibility?

A: Height differences must be evaluated against available board space in the target application. The original SH470M6R3ST has a maximum seated height of 0.433". Substitute parts range from 0.433" to 0.512". If board space is constrained, parts with heights matching or not exceeding 0.433" (UPW0J470MDD, UPS1A470MDD, UPW1A470MDD, 517D476M025JA6AE3, UPW1E470MDD) are preferred. Parts with heights up to 0.512" (SEK470M010ST) require verification of available clearance.

Q: Why are some substitute parts listed as obsolete?

A: Obsolete parts are no longer manufactured but may remain available through inventory channels. For new designs or long-term production requirements, active products such as SEK470M010ST, 476CKE035M, EEU-EB1E470S, EKZE250ELL470ME11D, and others provide sustained procurement viability and manufacturer support.

Q: What does the ±20% tolerance specification mean?

A: The ±20% tolerance indicates that the actual capacitance value may vary from the nominal 47 µF by up to 20% in either direction (37.6 µF to 56.4 µF). All listed substitute parts maintain this same tolerance specification, ensuring equivalent performance characteristics in applications where this tolerance is acceptable.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts listed in this reference are ROHS3 compliant, matching the environmental certification status of the original SH470M6R3ST.

Q: What is the significance of the 2000-hour lifetime rating at 105°C?

A: The 2000-hour lifetime at 105°C specifies the expected operational duration under maximum rated temperature conditions before capacitance degradation exceeds acceptable limits. Most substitute parts maintain this same 2000-hour rating. EEU-EB1E470S offers an extended 5000-hour rating, providing longer operational life under elevated temperature conditions.

Q: Can I substitute a 47 µF capacitor with a different capacitance value?

A: No. Capacitance is a critical electrical parameter. Substitution requires exact capacitance matching at 47 µF. Different capacitance values alter circuit behavior and are not acceptable substitutes.

Q: What does lead spacing of 0.079" (2.00 mm) mean?

A: Lead spacing specifies the distance between the two radial leads on the capacitor. This dimension is critical for through-hole PCB mounting. All substitute parts maintain identical 0.079" (2.00 mm) lead spacing, ensuring compatibility with existing PCB footprints designed for the original SH470M6R3ST.
