Key Parameters

Substitute Part Grouping Explanation

Substitution of the SH101M160ST is determined by strict adherence to the following electrical and mechanical parameters:

Primary Substitution Criteria:

• Capacitance: 100 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)
• Package / Case: Radial, Can (exact match required)
• Mounting Type: Through Hole (exact match required)
• Lead Spacing: 7.50 mm (exact match required)
• Diameter: 16.00 mm (exact match required)

Secondary Considerations:

• Lifetime @ 105°C: 2000 hours minimum (upgrades with longer lifetime acceptable)
• Operating Temperature Range: -25°C to 105°C minimum (extended ranges acceptable)
• ESR and Ripple Current: Specifications must meet or exceed original values
• RoHS Compliance: ROHS3 Compliant (maintained across all substitutes)

Substitute parts are grouped into two categories: Direct Equivalents (identical voltage rating) and Upgrades (higher voltage rating or extended lifetime). All substitutes maintain identical physical dimensions and mounting characteristics to ensure mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent (160 V Rating):

ECA-2CHG101 (Panasonic Electronic Components) is the primary direct equivalent. This part maintains the 160 V voltage rating and ±20% tolerance of the original SH101M160ST. The part is currently in active production status, ensuring long-term availability. It is ROHS3 compliant and REACH unaffected. The rated lifetime of 2000 hours at 105°C matches the original specification. Physical dimensions are compatible with the original footprint (16.00 mm diameter, 7.50 mm lead spacing). Height is 27.00 mm versus the original 25.00 mm, which may require verification in space-constrained applications.

Upgraded Equivalent (160 V Rating, Extended Lifetime):

EEU-EB2C101 (Panasonic Electronic Components) provides a 160 V substitute with extended lifetime of 5000 hours at 105°C. This part is active in production and ROHS3 compliant. The increased ripple current capability (583 mA @ 120 Hz, 1.06 A @ 100 kHz) exceeds the original specification. Height is 27.00 mm, requiring space verification.

Higher Voltage Upgrades (200 V Rating):

SEK101M200ST (Cornell Dubilier Electronics) is an active-status upgrade from the same manufacturer with 200 V rating. This part maintains the original 25.00 mm height and provides extended operating temperature range (-40°C to 105°C). Lifetime remains 2000 hours at 105°C.

EEU-EB2D101 (Panasonic Electronic Components) offers 200 V rating with 5000-hour lifetime at 105°C. ROHS3 compliant and active in production.

EEU-ED2D101 (Panasonic Electronic Components) provides the highest lifetime rating of 10000 hours at 105°C with 200 V rating. This part maintains the original 25.00 mm height and is active in production with ROHS3 compliance.

Highest Voltage Upgrade (250 V Rating):

EKXG251ELL101ML25S (Chemi-Con) is a 250 V rated substitute with 10000-hour lifetime at 105°C. This part is active in production, ROHS3 compliant, and maintains the original 25.00 mm height. Extended operating temperature range (-40°C to 105°C) is provided.

All recommended substitutes maintain through-hole mounting, radial can package, 7.50 mm lead spacing, and 16.00 mm diameter. Selection should be based on voltage margin requirements, lifetime expectations, and available board space for height variations.

Frequently Asked Questions (FAQ)

Q: Can I use a 200 V rated capacitor in place of the 160 V SH101M160ST?

A: Yes. Higher voltage-rated capacitors are acceptable substitutes provided all other parameters (capacitance, tolerance, package, mounting type, lead spacing, diameter) remain identical. A 200 V or 250 V rated part will function in a 160 V application. This provides additional voltage margin and is a common upgrade practice.

Q: What is the significance of the height difference between 25.00 mm and 27.00 mm?

A: The height difference of 2.00 mm may affect board layout in space-constrained designs. Verify available clearance above the capacitor location before selecting a substitute with increased height. Parts maintaining the original 25.00 mm height include SEK101M200ST, EEU-ED2D101, and EKXG251ELL101ML25S.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All substitute parts listed in this reference are ROHS3 compliant, maintaining environmental compliance with the original SH101M160ST.

Q: What does "Lifetime @ 105°C" mean, and why does it vary among substitutes?

A: Lifetime at 105°C specifies the expected operational duration of the capacitor under maximum rated temperature conditions. The original SH101M160ST has a 2000-hour lifetime. Substitutes with 5000-hour or 10000-hour ratings provide extended service life under thermal stress, reducing failure risk in high-temperature applications. Selection depends on application reliability requirements.

Q: Can I substitute an obsolete part (UPW2C101MHD) with another obsolete part?

A: Obsolete parts carry procurement risk due to limited remaining inventory. Active-status substitutes (ECA-2CHG101, EEU-EB2C101, EEU-EB2D101, EEU-ED2D101, EKXG251ELL101ML25S, SEK101M200ST) are preferred for new designs and long-term production. Obsolete substitutes should only be considered when active alternatives are unavailable.

Q: What is ESR, and why is it important?

A: Equivalent Series Resistance (ESR) represents the internal resistance of the capacitor at a specified frequency. Lower ESR values indicate better performance in high-frequency ripple current applications. The original SH101M160ST specifies 1.99 Ohm @ 120 Hz. Substitute parts with unspecified ESR values should be verified against application requirements before selection.

Q: Are the lead spacing and diameter identical across all substitutes?

A: Yes. All substitute parts maintain 7.50 mm lead spacing and 16.00 mm diameter, ensuring mechanical compatibility with the original footprint. Height variations (25.00 mm or 27.00 mm) are the only dimensional difference requiring verification.

Q: What does "Ripple Current" specification indicate?

A: Ripple current is the maximum AC current the capacitor can safely handle at specified frequencies (120 Hz for low frequency, 10 kHz or 100 kHz for high frequency). Higher ripple current ratings indicate greater capability to handle AC stress without degradation. Verify that substitute parts meet or exceed the original ripple current specifications for your application frequency.
