SH100M050ST Equivalent & Substitute Parts

Part Overview

The SH100M050ST is a 10 µF, 50 V aluminum electrolytic capacitor in radial, can package manufactured by Cornell Dubilier Electronics (CDE). This component is classified as obsolete, with 981 pieces available in current inventory. 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 the obsolete status of the SH100M050ST, identifying equivalent and substitute parts is necessary to ensure long-term component availability, support ongoing production requirements, and maintain design flexibility for new applications. Substitute parts must maintain electrical compatibility while meeting or exceeding the original specifications.

Substitute Part Grouping Explanation

Substitute parts for the SH100M050ST are classified into three categories based on electrical and mechanical compatibility:

Upgrade Substitutes (Direct Electrical Equivalents with Enhanced Performance): These parts maintain identical capacitance (10 µF), voltage rating (50 V), tolerance (±20%), and lead spacing (0.079" / 2.00 mm). They are suitable for direct replacement with potential improvements in lifetime, temperature range, or availability. Upgrade substitutes include SEK100M050ST and EEU-EB1H100S.

Direct Substitutes (Electrical Equivalents with Voltage Upgrade): EEU-EB1J100S maintains the same capacitance, tolerance, and physical dimensions but operates at 63 V rated voltage, providing additional voltage margin while remaining mechanically compatible.

Similar Substitutes (Different Technology or Voltage Class): 293D106X0016C2TE3 represents a tantalum capacitor technology with the same capacitance and tolerance but operates at 16 V. This part is suitable only for applications where voltage requirements are lower and surface-mount packaging is acceptable.

Key Parameters Determining Substitution: Capacitance value, voltage rating, tolerance, lead spacing, case diameter, height, mounting type, and package configuration.

Engineering Selection Recommendations

SEK100M050ST (Cornell Dubilier Electronics): This part is the primary recommended substitute. It maintains identical electrical specifications (10 µF, 50 V, ±20%, 15.92 Ohm ESR, 2000 Hrs @ 105°C) and physical dimensions as the SH100M050ST. The SEK100M050ST is active in production with 13,227 pieces in inventory, ensuring long-term availability. The extended operating temperature range (-55°C to 105°C) provides additional margin for low-temperature applications. Height increases to 0.512" (13.00 mm), requiring verification of PCB layout clearance. ROHS3 compliance and MSL 1 rating confirm environmental and moisture compatibility.

EEU-EB1H100S (Panasonic Electronic Components): This substitute offers enhanced reliability with 5000-hour lifetime at 105°C, double the original specification. Electrical parameters (10 µF, 50 V, ±20%) and physical dimensions (0.197" diameter, 0.079" lead spacing) are compatible. Height is 0.472" (12.00 mm), requiring PCB layout verification. Active production status with 8,216 pieces in inventory ensures availability. ROHS3 compliance and REACH unaffected status confirm regulatory compliance. Lower ripple current specifications (27 mA @ 120 Hz, 44.55 mA @ 100 kHz) indicate reduced thermal stress capability compared to the original part.

EEU-EB1J100S (Panasonic Electronic Components): This part provides voltage upgrade capability (63 V rated) while maintaining 10 µF capacitance and ±20% tolerance. It is suitable for applications where higher voltage margin is required. Physical compatibility is maintained with identical lead spacing and case diameter. Height is 0.472" (12.00 mm). Active production with 22,066 pieces in inventory provides excellent availability. ROHS3 compliance and REACH unaffected status confirm regulatory compliance. The 63 V rating allows use in circuits originally designed for 50 V operation with additional safety margin.

517D106M050JA6AE3 (Vishay Sprague): This part maintains electrical equivalence (10 µF, 50 V, ±20%, 2000 Hrs @ 105°C) and physical compatibility (0.079" lead spacing, 0.197" diameter, 0.433" height). However, obsolete product status and lower inventory (1,244 pieces) limit its suitability for new designs. Higher ripple current capability (100 mA @ 10 kHz) may benefit high-frequency applications. Extended temperature range (-55°C to 105°C) provides low-temperature margin. ROHS3 compliance and REACH unaffected status confirm regulatory compliance.

293D106X0016C2TE3 (Vishay Sprague - Tantalum Technology): This part is not recommended as a direct substitute due to fundamental technology differences. Tantalum capacitors operate at 16 V, significantly lower than the 50 V requirement. Surface-mount package (2312 / 6032 Metric) is incompatible with through-hole PCB designs. This part is suitable only for new designs where voltage requirements are lower and surface-mount assembly is specified.

Frequently Asked Questions (FAQ)

Q: Can SEK100M050ST be used as a direct replacement for SH100M050ST?

A: Yes. SEK100M050ST maintains identical capacitance (10 µF), voltage rating (50 V), tolerance (±20%), ESR (15.92 Ohm @ 120 Hz), and lifetime (2000 Hrs @ 105°C). Lead spacing (0.079" / 2.00 mm) and case diameter (0.197" / 5.00 mm) are identical. Height increases from 0.433" to 0.512", requiring PCB layout verification to ensure clearance. Active production status and high inventory availability make this the preferred substitute.

Q: What is the difference between EEU-EB1H100S and EEU-EB1J100S?

A: Both parts are Panasonic aluminum electrolytic capacitors with 10 µF capacitance, ±20% tolerance, and identical physical dimensions. EEU-EB1H100S is rated at 50 V, matching the original SH100M050ST voltage specification. EEU-EB1J100S is rated at 63 V, providing higher voltage margin. Both offer 5000-hour lifetime at 105°C, compared to 2000 hours for the original part. Selection depends on circuit voltage requirements and desired reliability margin.

Q: Why is 293D106X0016C2TE3 listed as a substitute if it operates at 16 V?

A: 293D106X0016C2TE3 is classified as a similar substitute based on matching capacitance (10 µF) and tolerance (±20%). However, the 16 V voltage rating is significantly lower than the 50 V requirement of the SH100M050ST. This part is suitable only for applications where circuit voltage is 16 V or lower. The surface-mount package (2312 / 6032 Metric) is incompatible with through-hole PCB designs. This part is not recommended for direct replacement of the SH100M050ST.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All substitute parts listed (SEK100M050ST, 517D106M050JA6AE3, EEU-EB1H100S, EEU-EB1J100S, and 293D106X0016C2TE3) are ROHS3 compliant, confirming compliance with hazardous substance restrictions.

Q: What is the impact of height differences on PCB design?

A: The SH100M050ST has a maximum seated height of 0.433" (11.00 mm). SEK100M050ST increases to 0.512" (13.00 mm), and both Panasonic parts (EEU-EB1H100S and EEU-EB1J100S) are 0.472" (12.00 mm). Height increases require verification of PCB layout clearance, particularly in applications with space constraints or where components are mounted near other tall components. 517D106M050JA6AE3 maintains the original 0.433" height.

Q: Which substitute offers the best long-term reliability?

A: EEU-EB1H100S and EEU-EB1J100S both offer 5000-hour lifetime at 105°C, compared to 2000 hours for the SH100M050ST and other substitutes. This represents a 2.5x improvement in rated lifetime. Both Panasonic parts are active in production with high inventory availability, supporting long-term component sourcing. Selection between these two depends on voltage requirements: EEU-EB1H100S for 50 V applications, EEU-EB1J100S for applications requiring 63 V rating.

Q: Can SEK100M050ST be used in low-temperature applications?

A: Yes. SEK100M050ST operates across -55°C to 105°C, compared to -40°C to 105°C for the SH100M050ST. The extended low-temperature range provides additional margin for applications requiring operation below -40°C. However, capacitor performance characteristics at extreme temperatures should be verified against specific circuit requirements.

Q: What is the inventory status of each substitute?

A: SEK100M050ST has 13,227 pieces in stock. EEU-EB1H100S has 8,216 pieces. EEU-EB1J100S has 22,066 pieces (highest availability). 517D106M050JA6AE3 has 1,244 pieces. 293D106X0016C2TE3 has 4,875 pieces. For long-term production requirements, EEU-EB1J100S offers the highest inventory buffer.
