SH101M016ST Equivalent & Substitute Parts Reference

Part Overview

The SH101M016ST is a 100 µF, 16 V aluminum electrolytic capacitor in radial, can package manufactured by Cornell Dubilier Electronics (CDE). This component is classified as obsolete, with 794 units currently in stock. The part is designed for general-purpose applications requiring through-hole mounting with a 0.098" (2.50 mm) lead spacing and operates across a temperature range of -40°C to 105°C with a rated lifetime of 2000 hours at 105°C.

Due to its obsolete status, identifying equivalent and substitute parts is necessary for ongoing design support, maintenance, and production continuity. Substitute parts must maintain electrical compatibility while meeting the same mechanical and environmental specifications.

Substitute Part Grouping Explanation

Substitution of the SH101M016ST is determined by strict adherence to the following electrical and mechanical parameters:

Primary Substitution Criteria:

Capacitance: 100 µF (exact match required)
Voltage Rating: 16 V minimum (higher voltage ratings are acceptable as upgrades)
Tolerance: ±20% (standard tolerance match)
Polarization: Polar (radial aluminum electrolytic)
Mounting Type: Through Hole
Lead Spacing: 0.098" (2.50 mm)
Package / Case: Radial, Can
Operating Temperature: Must support -40°C to 105°C minimum
RoHS Compliance: ROHS3 Compliant

Secondary Compatibility Parameters:

ESR and ripple current ratings must be equal to or better than the original specification
Lifetime at 105°C should meet or exceed 2000 hours
Physical dimensions (case diameter and height) must accommodate the original PCB footprint

Substitutes are grouped into two categories: direct replacements (matching 16 V rating) and upgrades (higher voltage ratings of 25 V, which provide enhanced voltage margin while maintaining all other specifications).

Engineering Selection Recommendations

Direct Replacement (16 V Rating):

The SEK101M016ST (Cornell Dubilier Electronics, Active status) is the primary direct replacement for the SH101M016ST. Both parts share identical electrical specifications (100 µF, 16 V, ±20%, 2.39 Ohm ESR, 2000 Hrs @ 105°C). The SEK series represents an active product line with superior availability (14,111 units in stock versus 794 for the original SH series). The SEK101M016ST extends the operating temperature range to -55°C to 105°C, providing enhanced cold-temperature performance. Case diameter increases from 6.00 mm to 6.30 mm; PCB layout verification is required to confirm accommodation of this dimensional change.

The UPW1C101MED (Nichicon, Obsolete status) provides equivalent 16 V electrical performance with superior ripple current capability (188.5 mA @ 120 Hz versus 135 mA). However, its obsolete status limits long-term availability.

Upgrade Substitutes (25 V Rating):

Three active-status parts rated at 25 V provide voltage margin upgrades while maintaining 100 µF capacitance and ±20% tolerance:

EEU-EB1E101S (Panasonic, Active): Offers extended lifetime of 5000 hours @ 105°C (versus 2000 hours). Height increases to 12.20 mm; dimensional verification required. Ripple current is lower (95 mA @ 120 Hz), suitable for low-ripple applications.
EKZE250ELL101MF11D (Chemi-Con, Active): Maintains 11.00 mm height (compatible with original footprint). Provides superior ripple current (162 mA @ 120 Hz) and impedance (130 mOhms). Lifetime matches original specification at 2000 hours @ 105°C.
UHE1E101MED (Nichicon, Obsolete): Delivers highest ripple current (238 mA @ 120 Hz) and extended lifetime (5000 hours @ 105°C). Despite obsolete status, 176,517 units are in stock, providing immediate availability.

All substitute parts maintain ROHS3 compliance and through-hole radial can package configuration. Selection should prioritize active-status parts (SEK101M016ST, EEU-EB1E101S, EKZE250ELL101MF11D) for long-term supply chain stability.

Frequently Asked Questions (FAQ)

Q: Can the SEK101M016ST directly replace the SH101M016ST without PCB modification?

A: Electrical compatibility is confirmed. However, the case diameter increases from 6.00 mm to 6.30 mm. PCB pad spacing and component clearance must be verified. Lead spacing remains identical at 0.098" (2.50 mm).

Q: What is the advantage of selecting a 25 V rated substitute over the 16 V direct replacement?

A: A 25 V rated capacitor provides voltage margin, reducing stress on the component in applications with voltage transients or ripple. All 25 V substitutes maintain identical capacitance (100 µF) and tolerance (±20%), ensuring circuit performance. The trade-off is increased case diameter (6.30 mm) for most 25 V options.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts carry ROHS3 Compliant certification, meeting environmental and hazardous substance restrictions.

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

A: The SEK101M016ST (Cornell Dubilier, Active status) and EKZE250ELL101MF11D (Chemi-Con, Active status) are recommended for long-term supply chain stability. Both are active products with substantial inventory levels.

Q: Does the operating temperature range affect substitution compatibility?

A: The SH101M016ST operates from -40°C to 105°C. All substitutes support this range or exceed it. The SEK101M016ST extends to -55°C, providing enhanced cold-temperature performance. This does not restrict substitution but may provide additional design margin.

Q: What is the significance of ESR (Equivalent Series Resistance) in selecting a substitute?

A: ESR affects ripple current handling and heat dissipation. The original SH101M016ST specifies 2.39 Ohm @ 120 Hz. Substitutes with lower ESR (such as EKZE250ELL101MF11D at 130 mOhms impedance) provide superior high-frequency performance. Substitutes with equal or lower ESR are acceptable.

Q: Can the UPW1C101MED be used despite its obsolete status?

A: The UPW1C101MED is electrically compatible and currently has 2,944 units in stock. However, its obsolete status indicates no future production. Use is acceptable for immediate requirements but not recommended for new designs or long-term production planning.

Q: What is the difference between "Lifetime @ 105°C" specifications?

A: Lifetime indicates the expected operational duration at maximum rated temperature before capacitance degradation exceeds tolerance limits. The original part specifies 2000 hours. Substitutes offering 5000 hours (EEU-EB1E101S, UHE1E101MED) provide extended service life in high-temperature environments. This does not affect substitution compatibility but indicates enhanced reliability for demanding applications.
