Engineering Selection Recommendations

Recommended Primary Substitute: SEK2R2M160ST

The SEK2R2M160ST is the direct equivalent upgrade from Cornell Dubilier Electronics. It maintains identical electrical specifications (2.2 µF, 160 V, ±20% tolerance, 2000 Hrs @ 105°C) with marginally equivalent ESR (90.47 Ω vs. 90.43 Ω). The SEK2R2M160ST is an active product with extended operating temperature range (-40°C vs. -25°C) and improved moisture sensitivity rating (MSL 1 Unlimited). This part is the preferred choice for direct replacement in existing designs.

Alternative Upgrade Substitutes:

SEK2R2M200ST provides voltage margin upgrade to 200 V while maintaining all other electrical parameters. This part is suitable for applications where higher voltage headroom is beneficial for circuit reliability. Case diameter increases slightly (6.30 mm vs. 6.00 mm) and height increases to 0.453" (11.50 mm). Verify PCB layout clearance before selection.

SEK2R2M250ST offers maximum voltage rating at 250 V with enhanced ripple current capability (29 mA @ 120 Hz, 46.4 mA @ 10 kHz vs. 25 mA and 40 mA respectively). This part is suitable for high-ripple-current applications or designs requiring maximum voltage safety margin. Physical dimensions match SEK2R2M200ST.

Alternative Direct Substitutes (Nichicon):

UPW2C2R2MED is a direct equivalent from Nichicon with identical electrical specifications and physical dimensions to SH2R2M160ST. Product status is obsolete. This part is suitable for applications where Nichicon qualification is required or preferred.

UPW2D2R2MED provides voltage upgrade to 200 V from Nichicon. Product status is obsolete. This part is suitable for applications requiring Nichicon sourcing with voltage margin.

Selection Criteria Summary:

For direct replacement with active product support: SEK2R2M160ST
For voltage margin and enhanced reliability: SEK2R2M200ST or SEK2R2M250ST
For Nichicon-qualified designs: UPW2C2R2MED (equivalent) or UPW2D2R2MED (upgraded)

Frequently Asked Questions (FAQ)

Q: Can SEK2R2M160ST be used as a direct replacement for SH2R2M160ST?

A: Yes. The SEK2R2M160ST is electrically and mechanically equivalent with identical capacitance (2.2 µF), voltage rating (160 V), tolerance (±20%), lifetime (2000 Hrs @ 105°C), ripple current specifications, and lead spacing (0.098" / 2.50 mm). The SEK2R2M160ST is an active product with extended operating temperature range (-40°C to 105°C vs. -25°C to 105°C) and improved moisture sensitivity rating. No circuit redesign is required.

Q: What is the difference between SEK2R2M160ST, SEK2R2M200ST, and SEK2R2M250ST?

A: All three parts share identical capacitance (2.2 µF), tolerance (±20%), and lifetime (2000 Hrs @ 105°C). The primary differences are voltage rating and physical dimensions. SEK2R2M160ST is rated 160 V with 0.433" height. SEK2R2M200ST is rated 200 V with 0.453" height. SEK2R2M250ST is rated 250 V with 0.453" height and enhanced ripple current (29 mA @ 120 Hz, 46.4 mA @ 10 kHz). Selection depends on circuit voltage requirements and available PCB space.

Q: Can I use a higher voltage-rated part (200 V or 250 V) in place of the 160 V SH2R2M160ST?

A: Yes. Higher voltage-rated capacitors are electrically compatible in circuits designed for lower voltages. The 200 V and 250 V rated parts provide additional voltage safety margin. However, verify PCB layout clearance, as case diameter increases from 6.00 mm to 6.30 mm and height increases from 0.433" to 0.453" for the 200 V and 250 V versions.

Q: Are Nichicon UPW2C2R2MED and UPW2D2R2MED suitable substitutes?

A: Yes. UPW2C2R2MED is electrically and mechanically equivalent to SH2R2M160ST with identical specifications. UPW2D2R2MED provides voltage upgrade to 200 V. Both parts are ROHS3 compliant and maintain 2000 Hrs @ 105°C lifetime. However, both Nichicon parts are classified as obsolete. For new designs requiring long-term availability, the active CDE SEK series is preferred.

Q: What are the physical dimension differences between substitute parts?

A: SH2R2M160ST and SEK2R2M160ST share identical dimensions: 0.236" to 0.248" diameter and 0.433" height. SEK2R2M200ST and SEK2R2M250ST have larger diameter (0.248") and increased height (0.453"). UPW2C2R2MED matches SH2R2M160ST dimensions. UPW2D2R2MED matches SH2R2M160ST dimensions. Verify PCB layout and clearance requirements before selecting higher-voltage alternatives with increased physical size.

Q: Do all substitute parts meet RoHS compliance?

A: Yes. All substitute parts listed (SEK2R2M160ST, SEK2R2M200ST, SEK2R2M250ST, UPW2C2R2MED, UPW2D2R2MED) are ROHS3 compliant, matching the compliance status of the original SH2R2M160ST.

Q: What is the operating temperature range for each substitute?

A: SH2R2M160ST operates -25°C to 105°C. All substitute parts (SEK series and UPW series) operate -40°C to 105°C, providing extended low-temperature capability. This is an improvement over the original part.

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

A: SEK2R2M160ST is the recommended choice for long-term availability. It is an active product from Cornell Dubilier Electronics with the same manufacturer as the original SH2R2M160ST. The SEK series provides continuity of supply and technical support. Nichicon UPW parts are obsolete and should be avoided for new designs requiring extended production support.
