Equivalent & Substitute Parts for SH470M160ST

Part Overview

The SH470M160ST is a 47 µF, 160 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 in the supply chain. The SH series represents an older generation of general-purpose aluminum electrolytic capacitors with a rated lifetime of 2000 hours at 105°C. Due to its obsolete status, equivalent and substitute parts from active product lines are necessary to maintain design continuity and ensure long-term component availability for new production runs and field replacements.

Substitute Part Grouping Explanation

Substitution of the SH470M160ST 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: 160 V minimum (equal or higher voltage rating acceptable)
Polarization: Polar (exact match required)
Lead Spacing: 5.00 mm (exact match required)
Mounting Type: Through Hole, Radial (exact match required)
Package / Case: Radial, Can (exact match required)

Secondary Compatibility Parameters:

Operating Temperature Range: Must encompass or exceed -25°C to 105°C
RoHS Status: ROHS3 Compliant (required for regulatory compliance)
Ripple Current Ratings: Must meet or exceed specified values at 120 Hz and 10 kHz

Substitute parts are grouped into two categories:

Category 1: Direct Equivalents (160 V Rating) Parts maintaining the original 160 V voltage specification with identical capacitance, tolerance, lead spacing, and package configuration. These parts provide direct pin-for-pin and form-factor compatibility.

Category 2: Upgraded Equivalents (160 V to 250 V Rating) Parts with higher voltage ratings (250 V) that maintain all other electrical and mechanical parameters. These parts provide enhanced voltage margin and are suitable for applications where the original 160 V specification can accommodate higher-rated components without design modification.

Engineering Selection Recommendations

For Direct Replacement (160 V Specification Maintained):

The SEK470M160ST from Cornell Dubilier Electronics is the primary recommended substitute. This part maintains active product status, identical electrical specifications at 160 V, and ROHS3 compliance. The SEK series represents the current generation replacement for the obsolete SH series. The extended operating temperature range (-40°C to 105°C) provides improved performance margin in low-temperature environments compared to the original SH470M160ST.

The EEU-EB2C470 from Panasonic Electronic Components is an alternative direct equivalent with active product status. This part offers extended lifetime (5000 hours at 105°C versus 2000 hours), providing improved reliability for long-term applications. Dimensional variations (12.50 mm diameter, 22.00 mm height) must be verified for PCB layout compatibility.

For Enhanced Reliability (160 V to 250 V Upgrade):

The EEU-ED2E470 from Panasonic Electronic Components is recommended for applications requiring extended operational lifetime and higher voltage margin. This part features 10,000-hour lifetime at 105°C, active product status, and ROHS3 compliance. The 250 V rating provides additional safety margin in circuits with voltage transients. Height dimension (25.00 mm) matches the original SH470M160ST, simplifying mechanical integration.

The EEU-EB2E470 from Panasonic Electronic Components offers similar benefits with 5000-hour lifetime and 250 V rating. The increased height (27.00 mm) requires verification against PCB clearance constraints.

Obsolete Parts (Not Recommended for New Designs):

The UCA2C470MHD, UPW2C470MHD, and UPW2D470MHD are classified as obsolete and should not be selected for new production designs. These parts are suitable only for field replacement of existing assemblies where supply chain continuity is critical.

Frequently Asked Questions (FAQ)

Q1: Can the SEK470M160ST directly replace the SH470M160ST without PCB modification?

The SEK470M160ST maintains identical electrical specifications, lead spacing (5.00 mm), and mounting type (through-hole radial). However, the reduced height (21.00 mm versus 25.00 mm) and diameter (13.00 mm versus 13.00 mm for SH) require verification of PCB layout clearances. In most applications, this substitution is direct; however, mechanical fit must be confirmed for each specific PCB design.

Q2: What is the advantage of selecting a 250 V rated capacitor (EEU-EB2E470 or EEU-ED2E470) instead of a 160 V equivalent?

Higher voltage-rated capacitors provide increased safety margin against voltage transients and overvoltage conditions. The 250 V parts also offer extended lifetime ratings (5000 to 10000 hours at 105°C versus 2000 hours for the original SH470M160ST), improving long-term reliability. The trade-off is increased physical height, which must be accommodated in the PCB layout.

Q3: Are all substitute parts ROHS3 compliant?

Yes. All substitute parts listed in this reference maintain ROHS3 compliance, meeting current regulatory requirements for lead-free and restricted substance compliance.

Q4: What is the significance of the operating temperature range difference between -25°C and -40°C?

The SEK470M160ST and UPW series parts extend the lower operating temperature limit to -40°C, providing improved performance in cold-environment applications. The original SH470M160ST is limited to -25°C. This difference is significant for applications in outdoor, aerospace, or industrial environments subject to low-temperature exposure.

Q5: Can the UPW2D470MHD (200 V) be used as a substitute for the SH470M160ST (160 V)?

The UPW2D470MHD maintains identical capacitance, tolerance, lead spacing, and mounting configuration. The 200 V rating exceeds the 160 V specification, providing voltage margin. However, this part is classified as obsolete and should not be selected for new designs. For field replacement only, this part is electrically compatible.

Q6: How do ripple current ratings affect substitution decisions?

Ripple current capacity must meet or exceed the original specification to ensure thermal stability and prevent premature capacitor failure. The SH470M160ST specifies 270 mA at 120 Hz and 432 mA at 10 kHz. All listed substitutes meet or exceed these values. Higher ripple current capacity indicates improved thermal performance and is beneficial for high-frequency switching applications.

Q7: What is the difference between the EEU-EB2C470 and EEU-ED2E470?

Both are Panasonic parts with 47 µF capacitance and 160 V / 250 V ratings respectively. The EEU-ED2E470 features extended lifetime (10,000 hours at 105°C versus 5,000 hours) and higher voltage rating (250 V). The EEU-EB2C470 is suitable for general-purpose applications with standard reliability requirements, while the EEU-ED2E470 is recommended for critical applications requiring extended operational life.

Q8: Are there any MSL (Moisture Sensitivity Level) considerations for these substitutes?

The original SH470M160ST has MSL not applicable. The EEU-ED2E470 specifies MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. All other substitutes specify MSL not applicable. This difference does not affect substitution compatibility for through-hole radial components.
