Substitute Part Grouping Explanation

Substitute parts for the SH100M100ST are qualified based on the following electrical and mechanical parameters:

Electrical Equivalence Criteria:

• Capacitance: 10 µF (exact match required)
• Voltage Rating: 100 V (exact match required)
• Tolerance: ±20% (exact match required)
• Lifetime: 2000 Hrs @ 105°C (exact match required)
• Polarization: Polar (required for electrolytic capacitors)

Mechanical Compatibility Criteria:

• Lead Spacing: 0.098" (2.50mm) (exact match required for PCB compatibility)
• Package Type: Radial, Can (exact match required)
• Mounting Type: Through Hole (exact match required)
• Height - Seated (Max): 0.433" (11.00mm) (acceptable within standard tolerance)

Regulatory Compliance Criteria:

• RoHS3 Compliant (all substitutes meet this requirement)
• ECCN: EAR99 (all substitutes classified identically)
• HTSUS: 8532.22.0020 (all substitutes classified identically)

The two qualified substitute parts meet all critical electrical and mechanical parameters. Dimensional variations in can diameter (6.00mm vs. 6.30mm) remain within acceptable tolerances for radial can capacitors and do not affect PCB mounting compatibility given identical lead spacing.

Engineering Selection Recommendations

SEK100M100ST (CDE Upgrade - Recommended Primary Substitute)

The SEK100M100ST is the direct upgrade path within the Cornell Dubilier Electronics product portfolio. This part maintains identical electrical specifications (10 µF, ±20%, 100 V, 2000 Hrs @ 105°C) and mechanical compatibility (lead spacing, package type, mounting method). The SEK series is classified as Active product status, ensuring long-term supply availability and manufacturing continuity. The extended operating temperature range (-55°C to 105°C) provides broader environmental compatibility compared to the SH series (-40°C to 105°C). RoHS3 compliance and REACH unaffected status confirm regulatory alignment. Current inventory of 1199 pieces supports immediate deployment.

UPW2A100MED (Nichicon - Secondary Substitute)

The UPW2A100MED from Nichicon provides electrical and mechanical equivalence with identical capacitance, voltage rating, tolerance, and lifetime specifications. Lead spacing and package configuration match the SH100M100ST exactly. This part is classified as Obsolete product status; however, current inventory of 5200 pieces indicates availability for near-term requirements. The UPW series demonstrates superior ripple current performance at high frequencies (130 mA @ 100 kHz versus 91 mA @ 10 kHz for the SH series), which may provide operational advantages in high-frequency applications. RoHS3 compliance and REACH unaffected status confirm regulatory alignment.

Selection Logic:

For new designs and ongoing production requiring long-term supply assurance, SEK100M100ST is the preferred substitute due to active product status. For applications where existing inventory must be consumed or where the superior high-frequency ripple current performance of the UPW2A100MED provides design benefits, the Nichicon part remains electrically and mechanically compatible. Both substitutes satisfy all critical parameters that determine functional equivalence.

Frequently Asked Questions (FAQ)

Q: Can the SEK100M100ST be used as a direct replacement for the SH100M100ST without PCB modifications?

A: Yes. The SEK100M100ST maintains identical lead spacing (0.098" / 2.50mm), package type (Radial, Can), and mounting method (Through Hole). The can diameter increases from 6.00mm to 6.30mm; however, this dimensional change does not affect PCB footprint compatibility or mounting hole alignment. No PCB layout modifications are required.

Q: What is the significance of the extended operating temperature range in the SEK100M100ST (-55°C to 105°C versus -40°C to 105°C)?

A: The SEK series supports operation at lower ambient temperatures (-55°C minimum) compared to the SH series (-40°C minimum). This extended range provides compatibility with applications requiring broader environmental tolerance. For applications operating within the original SH range (-40°C to 105°C), both parts perform identically.

Q: Are there differences in ESR (Equivalent Series Resistance) between the SH100M100ST and its substitutes?

A: The SH100M100ST specifies ESR of 13.26 Ohm @ 120Hz. The SEK100M100ST specifies 13.27 Ohm, representing negligible difference (0.01 Ohm). The UPW2A100MED does not specify ESR in the provided data; however, impedance is listed as 1.8 Ohms, which is not directly comparable to ESR measurements at specific frequencies. For applications sensitive to ESR specifications, the SEK100M100ST provides the closest electrical match.

Q: What is the difference in ripple current ratings between these parts?

A: The SH100M100ST specifies 65 mA @ 120 Hz and 91 mA @ 10 kHz. The UPW2A100MED specifies 39 mA @ 120 Hz and 130 mA @ 100 kHz. The UPW series demonstrates lower ripple current at low frequencies but superior performance at high frequencies. The SEK100M100ST does not specify ripple current in the provided data. For applications with defined ripple current requirements, verify that the selected substitute meets the specific frequency and amplitude requirements of your circuit.

Q: Are all three parts RoHS3 compliant?

A: Yes. The SH100M100ST, SEK100M100ST, and UPW2A100MED are all classified as ROHS3 Compliant. All three parts are also classified under ECCN EAR99 and HTSUS 8532.22.0020, confirming identical regulatory and trade classification status.

Q: Why is the SEK100M100ST recommended as the primary substitute despite the UPW2A100MED having higher inventory?

A: The SEK100M100ST is recommended as primary substitute due to Active product status, which ensures long-term manufacturing support and supply chain continuity. The UPW2A100MED, while currently in stock with higher inventory (5200 pieces), is classified as Obsolete, indicating discontinued production. For applications requiring sustained component availability beyond current inventory levels, the active SEK series provides superior long-term reliability.

Q: Can the UPW2A100MED be used in applications where high-frequency ripple current performance is critical?

A: Yes. The UPW2A100MED specifies 130 mA @ 100 kHz ripple current, which exceeds the SH100M100ST specification of 91 mA @ 10 kHz. For applications operating at high frequencies with significant ripple current demands, the UPW series may provide performance advantages. Verify that your specific application frequency and ripple current requirements align with the UPW2A100MED specifications.
