Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SH010M050ST is determined by strict equivalence across the following parameters:

Primary Electrical Parameters:

• Capacitance: 1 µF (exact match required)
• Voltage Rating: 50 V (exact match required)
• Tolerance: ±20% (exact match required)
• Polarization: Polar (exact match required)

Primary Mechanical Parameters:

• Package Type: Radial, Can (exact match required)
• Mounting Type: Through Hole (exact match required)
• Lead Spacing: 0.079" (2.00 mm) (exact match required)

Secondary Electrical Parameters (allowable variation):

• ESR (Equivalent Series Resistance): Variation permitted within component manufacturing tolerances
• Ripple Current: Variation permitted; higher values indicate improved performance
• Operating Temperature Range: Variation permitted; wider ranges indicate enhanced capability

Compliance Parameters:

• RoHS Status: ROHS3 Compliant (required for all substitutes)
• Moisture Sensitivity Level: 1 (Unlimited) (required for all substitutes)

All substitute parts listed meet these criteria and are sourced from Cornell Dubilier Electronics or affiliated manufacturers.

Parameter Comparison

Engineering Selection Recommendations

SEK010M050ST (Upgrade Substitute): The SEK010M050ST is an active-status product from Cornell Dubilier Electronics with equivalent electrical specifications to the SH010M050ST. This part features an extended operating temperature range (-55°C to 105°C) compared to the main part (-40°C to 105°C), providing enhanced low-temperature performance. ESR values are virtually identical (159.24 Ohm vs. 159.15 Ohm @ 120 Hz). The primary dimensional difference is increased height (13.00 mm vs. 11.00 mm), which must be verified for PCB layout compatibility. ROHS3 compliance and unlimited MSL rating are maintained. Inventory availability is 3345 pieces.

105CKH050M (Direct Substitute): The 105CKH050M is an active-status product from Cornell Dubilier / Illinois Capacitor with equivalent electrical specifications. ESR is slightly elevated at 165.79 Ohm @ 120 Hz (compared to 159.15 Ohm), representing a 4.2% increase within acceptable manufacturing tolerances. Ripple current performance at high frequency (29.9 mA @ 100 kHz) exceeds the main part specification. Height is 12.50 mm, intermediate between the main part and SEK substitute. Operating temperature range matches the main part (-40°C to 105°C). ROHS3 compliance and unlimited MSL rating are maintained. Inventory availability is 32603 pieces, providing superior supply chain security.

Both substitutes maintain all critical electrical and mechanical parameters required for direct functional replacement in general-purpose applications. Selection between SEK010M050ST and 105CKH050M should be based on PCB layout constraints (height tolerance) and supply chain requirements.

Frequently Asked Questions (FAQ)

Q: Can the SEK010M050ST be used as a direct replacement for the SH010M050ST on existing PCBs?

A: The SEK010M050ST is electrically equivalent but has a maximum seated height of 13.00 mm compared to 11.00 mm for the SH010M050ST. PCB layout must accommodate this 2.00 mm height increase. All other mechanical parameters (lead spacing, diameter, mounting type) are identical.

Q: What is the significance of the ESR difference between the main part and substitutes?

A: ESR (Equivalent Series Resistance) values are 159.15 Ohm (SH010M050ST), 159.24 Ohm (SEK010M050ST), and 165.79 Ohm (105CKH050M). These variations fall within normal manufacturing tolerances for aluminum electrolytic capacitors. The 105CKH050M shows a 4.2% increase, which does not affect functional performance in general-purpose applications.

Q: Why is the 105CKH050M recommended despite higher ESR?

A: The 105CKH050M offers superior inventory availability (32603 pieces vs. 1007 for the main part and 3345 for the SEK substitute). The ESR increase is within acceptable tolerances, and ripple current performance at high frequency is enhanced. This part provides optimal supply chain continuity.

Q: Are there any compliance or certification differences between the three parts?

A: All three parts are ROHS3 compliant with MSL rating of 1 (Unlimited). The SEK010M050ST and 105CKH050M both carry REACH Unaffected status. All parts share identical ECCN (EAR99) and HTSUS (8532.22.0020) classifications.

Q: What is the impact of the extended temperature range in the SEK010M050ST?

A: The SEK010M050ST operates from -55°C to 105°C, compared to -40°C to 105°C for both the main part and 105CKH050M. This extended low-temperature capability provides additional design margin for applications exposed to cold environments, though it does not affect performance in standard temperature ranges.

Q: Can these parts be used interchangeably in new designs?

A: Yes, all three parts meet the substitution criteria for 1 µF, 50 V, ±20% tolerance, polar, radial through-hole aluminum electrolytic capacitors. Selection should account for PCB height constraints and supply chain availability. The 105CKH050M is recommended for new designs due to superior inventory levels.
