SEK2R2M160ST Equivalent & Substitute Parts

Part Overview

The SEK2R2M160ST is a 2.2 µF, 160 V aluminum electrolytic capacitor in radial, can package manufactured by Cornell Dubilier Electronics (CDE). This component is classified as Active product status and is designed for general-purpose applications requiring through-hole mounting. The part operates across a temperature range of -40°C to 105°C with a rated lifetime of 2000 hours at 105°C.

Substitute parts become necessary when the original SEK2R2M160ST reaches end-of-life status, inventory depletion, or when design requirements permit operation at higher voltage ratings while maintaining core electrical characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SEK2R2M160ST is determined by the following critical parameters:

Mandatory Matching Parameters:

• Capacitance: 2.2 µF (exact match required)
• Tolerance: ±20% (exact match required)
• Operating Temperature Range: -40°C to 105°C (exact match required)
• Lifetime @ 105°C: 2000 Hrs (exact match required)
• Ripple Current @ 120 Hz: 25 mA (exact match required)
• Ripple Current @ 10 kHz: 40 mA (exact match required)
• Lead Spacing: 0.098" (2.50mm) (exact match required)
• Size / Dimension: 0.248" Dia (6.30mm) (exact match required)
• Height - Seated (Max): 0.433" (11.00mm) (exact match required)
• Mounting Type: Through Hole (exact match required)
• Package / Case: Radial, Can (exact match required)
• Polarization: Polar (exact match required)

Allowable Variation Parameters:

• Voltage - Rated: May be equal to or greater than 160 V
• Manufacturer: May differ from Cornell Dubilier Electronics
• Product Status: May differ from Active
• ESR: May differ when not specified in substitute part

Substitute parts meeting all mandatory parameters and voltage rating equal to or exceeding 160 V are electrically and mechanically compatible with the SEK2R2M160ST.

Parameter Comparison

Engineering Selection Recommendations

UPW2C2R2MED (Parametric Equivalent): The UPW2C2R2MED manufactured by Nichicon provides parametric equivalence to the SEK2R2M160ST. Both parts share identical capacitance (2.2 µF), voltage rating (160 V), tolerance (±20%), operating temperature range (-40°C to 105°C), and mechanical dimensions. Both are ROHS3 compliant and rated for 2000 hours at 105°C. The UPW2C2R2MED is classified as Obsolete product status. Selection of this substitute is appropriate when parametric matching is the primary requirement and product status is not a constraint.

UPW2D2R2MED (Upgrade): The UPW2D2R2MED manufactured by Nichicon provides an upgrade path with a higher voltage rating of 200 V while maintaining all other critical parameters identical to the SEK2R2M160ST. This part is suitable for applications where voltage margin is beneficial or where circuit design permits operation at elevated voltage ratings. The UPW2D2R2MED is classified as Obsolete product status and is ROHS3 compliant. The higher voltage rating does not degrade performance in circuits designed for 160 V operation.

Both substitute parts maintain mechanical compatibility through identical lead spacing, diameter, height, and through-hole mounting configuration. Both are ROHS3 compliant and REACH unaffected, matching the compliance profile of the original part.

Frequently Asked Questions (FAQ)

Q: Can the UPW2C2R2MED be used as a direct replacement for the SEK2R2M160ST?

A: Yes. The UPW2C2R2MED is a parametric equivalent with identical capacitance (2.2 µF), voltage rating (160 V), tolerance (±20%), operating temperature range, ripple current specifications, and mechanical dimensions. Both parts are through-hole mounted in radial, can packages with identical lead spacing and physical footprint.

Q: What is the difference between the UPW2C2R2MED and UPW2D2R2MED?

A: The primary difference is the voltage rating. The UPW2C2R2MED is rated at 160 V, matching the SEK2R2M160ST exactly. The UPW2D2R2MED is rated at 200 V, providing a higher voltage margin. All other electrical and mechanical parameters are identical between these two Nichicon parts.

Q: Can the UPW2D2R2MED (200 V) be used in place of the SEK2R2M160ST (160 V)?

A: Yes. The UPW2D2R2MED operates at a higher voltage rating and maintains all other critical parameters. In circuits designed for 160 V operation, the 200 V rated part functions without degradation and provides additional voltage margin.

Q: Are the substitute parts mechanically compatible with the original PCB layout?

A: Yes. Both UPW2C2R2MED and UPW2D2R2MED maintain identical lead spacing (0.098" / 2.50mm), diameter (0.248" / 6.30mm), and maximum seated height (0.433" / 11.00mm). Both are through-hole mounted radial, can packages and fit existing PCB footprints designed for the SEK2R2M160ST.

Q: Do the substitute parts meet the same compliance standards?

A: Yes. Both UPW2C2R2MED and UPW2D2R2MED are ROHS3 compliant and REACH unaffected, matching the compliance profile of the SEK2R2M160ST.

Q: What is the significance of the Obsolete product status for the substitute parts?

A: Obsolete status indicates that these parts are no longer in active production by the manufacturer. However, they remain electrically and mechanically compatible with the SEK2R2M160ST. Inventory availability may be limited compared to active products.

Q: Are ripple current specifications identical across all three parts?

A: Yes. All three parts—SEK2R2M160ST, UPW2C2R2MED, and UPW2D2R2MED—are rated for 25 mA ripple current at 120 Hz and 40 mA ripple current at 10 kHz.

Q: Can these parts be used interchangeably in high-frequency applications?

A: Yes. All three parts maintain identical ripple current specifications at both low frequency (120 Hz) and high frequency (10 kHz), supporting interchangeability across frequency ranges within the specified operating parameters.
