SH470M035ST Equivalent & Substitute Parts

Part Overview

The SH470M035ST is a 47 µF, 35 V aluminum electrolytic capacitor in radial, can package manufactured by Cornell Dubilier Electronics (CDE). This component is classified as obsolete, indicating discontinued production and limited availability for new designs. The part operates across a temperature range of -40°C to 105°C with a rated lifetime of 2000 hours at 105°C, suitable for general-purpose applications requiring stable capacitance and low equivalent series resistance.

Due to its obsolete status, equivalent and substitute parts from active manufacturers provide continuity for existing designs, maintenance applications, and production requirements where the original SH470M035ST is no longer readily available.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SH470M035ST is determined by strict adherence to the following electrical and mechanical parameters:

Primary Substitution Criteria:

• Capacitance: 47 µF (exact match required)
• Tolerance: ±20% (exact match required)
• Voltage Rating: 35 V minimum (equal or higher voltage rating acceptable)
• Package Type: Radial, Can (exact match required)
• Lead Spacing: 0.098" (2.50mm) (exact match required)
• Mounting Type: Through Hole (exact match required)
• Polarization: Polar (exact match required)

Secondary Compatibility Factors:

• Operating temperature range must encompass the original -40°C to 105°C specification
• RoHS3 compliance required for regulatory alignment
• Physical dimensions must accommodate PCB layout constraints

Substitute parts are grouped into two categories: direct equivalents (matching all primary criteria at 35 V rating) and upgrades (matching all primary criteria with enhanced voltage rating or lifetime performance).

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent (35 V Rating):

SEK470M035ST is the primary direct equivalent to SH470M035ST. Both parts share identical electrical specifications: 47 µF capacitance, 35 V voltage rating, ±20% tolerance, and 3.95 Ohm ESR at 120 Hz. SEK470M035ST is manufactured by the same supplier (CDE) and maintains active product status, ensuring continued availability and supply chain reliability. The operating temperature range extends to -55°C, providing enhanced low-temperature performance. Physical dimensions are compatible with existing PCB layouts, with lead spacing and mounting type identical to the original part.

UPW1V470MED (Nichicon) provides an alternative direct equivalent at 35 V rating. This part maintains the same capacitance, tolerance, and voltage specification with identical lead spacing and through-hole mounting. However, UPW1V470MED carries obsolete product status, limiting long-term availability. The operating temperature range extends to -55°C. Ripple current performance at high frequency (290 mA @ 100 kHz) exceeds the original specification.

Upgrade Options (50 V Rating):

EEU-EB1H470S (Panasonic) and UPW1H470MED (Nichicon) provide upgraded substitutes with 50 V voltage rating. Both maintain 47 µF capacitance and ±20% tolerance. EEU-EB1H470S offers superior lifetime performance at 5000 hours @ 105°C compared to the original 2000 hours, with active product status ensuring availability. UPW1H470MED provides 2000-hour lifetime matching the original specification but carries obsolete status.

The 50 V rating provides voltage margin for applications where the original 35 V specification may approach operational limits. Physical compatibility is maintained through identical lead spacing and through-hole mounting, though EEU-EB1H470S exhibits increased seated height (12.20 mm versus 11.00 mm), requiring PCB layout verification.

Compliance and Certification:

All substitute parts maintain ROHS3 compliance, aligning with regulatory requirements. SEK470M035ST and EEU-EB1H470S carry active product status, providing supply chain continuity and manufacturer support. Selection between direct equivalents and upgrades depends on application voltage headroom requirements and lifetime performance expectations.

Frequently Asked Questions (FAQ)

Q: Can UPW1V470MED be used as a direct replacement for SH470M035ST?

A: UPW1V470MED meets all primary substitution criteria: 47 µF capacitance, 35 V voltage rating, ±20% tolerance, identical lead spacing (2.50 mm), and through-hole radial can package. However, UPW1V470MED carries obsolete product status, limiting future availability. SEK470M035ST is the preferred direct equivalent due to active product status from the same manufacturer.

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

A: Direct equivalents (SEK470M035ST, UPW1V470MED) maintain the original 35 V voltage rating and all electrical specifications. Upgrade substitutes (EEU-EB1H470S, UPW1H470MED) provide 50 V voltage rating, offering increased voltage margin. Upgrades are electrically compatible in applications designed for 35 V operation, as the higher voltage rating does not affect capacitance or tolerance performance.

Q: Are there physical dimension differences between substitute parts?

A: Lead spacing (2.50 mm) and mounting type (through-hole) are identical across all substitutes. Diameter specifications vary slightly: SH470M035ST measures 6.00 mm, while SEK470M035ST, UPW1V470MED, and UPW1H470MED measure 6.30 mm. EEU-EB1H470S measures 6.30 mm in diameter with increased seated height of 12.20 mm compared to 11.00 mm for other parts. PCB layout verification is required when substituting EEU-EB1H470S due to height difference.

Q: Which substitute offers the longest operational lifetime?

A: EEU-EB1H470S provides 5000 hours @ 105°C, compared to 2000 hours for the original SH470M035ST and other substitutes. This extended lifetime is achieved through Panasonic's EB-A series design and is applicable when enhanced reliability over extended operating periods is required.

Q: Is RoHS3 compliance maintained across all substitutes?

A: Yes. All substitute parts (SEK470M035ST, UPW1V470MED, EEU-EB1H470S, UPW1H470MED) are ROHS3 compliant, maintaining regulatory alignment with the original SH470M035ST.

Q: Can I use a 50 V rated substitute in a circuit designed for 35 V?

A: Yes. A 50 V rated capacitor (EEU-EB1H470S or UPW1H470MED) is electrically compatible in circuits designed for 35 V operation. The higher voltage rating provides additional safety margin and does not affect capacitance value or tolerance. Physical dimensions must be verified for PCB layout compatibility.

Q: What is the operating temperature range difference between substitutes?

A: SH470M035ST and EEU-EB1H470S operate from -40°C to 105°C. SEK470M035ST, UPW1V470MED, and UPW1H470MED extend the lower temperature limit to -55°C, providing enhanced cold-temperature performance. Application requirements determine whether extended low-temperature operation is necessary.

Q: Why is product status important when selecting a substitute?

A: Active product status (SEK470M035ST, EEU-EB1H470S) indicates ongoing manufacturing and supply chain availability, supporting long-term production requirements and design continuity. Obsolete status (SH470M035ST, UPW1V470MED, UPW1H470MED) indicates discontinued production, limiting availability for future orders and maintenance applications.
