Substitute Categories:

Upgrade Substitutes (SEK Series): Cornell Dubilier SEK010M200ST and SEK010M250ST offer active product status with enhanced operating temperature range (-40°C to 105°C) compared to the original -25°C specification. Both maintain identical capacitance, tolerance, lead spacing, height, and mounting characteristics. The SEK010M250ST provides additional voltage margin (250 V versus 200 V).

Direct Substitute (Nichicon UPW2D010MED): Maintains exact electrical specifications (1 µF, 200 V, ±20%, 2000 Hrs @ 105°C) with identical mechanical dimensions and lead spacing. Classified as obsolete but equivalent in performance characteristics.

Upgrade Substitute (Vishay Sprague 517D105M250AA6AE3): Provides equivalent electrical performance with upgraded voltage rating (250 V). Mechanical footprint and lead spacing remain compatible with the original design.

Engineering Selection Recommendations

Preferred Selection: SEK010M200ST or SEK010M250ST (Cornell Dubilier) are recommended as primary substitutes. Both components carry active product status, ensuring continued availability and manufacturing support. The SEK series provides enhanced operating temperature range (-40°C to 105°C) compared to the original specification, offering improved performance margin in low-temperature applications. Both maintain ROHS3 compliance and provide inventory availability of 10,564 and 696 units respectively.

Alternative Selection: UPW2D010MED (Nichicon) provides electrical and mechanical equivalence but carries obsolete product status, limiting long-term supply availability.

Higher Voltage Option: SEK010M250ST and 517D105M250AA6AE3 offer upgraded voltage rating (250 V) suitable for designs requiring additional voltage margin, though the 250 V rating exceeds the original 200 V requirement.

Compliance Considerations: All substitute parts maintain ROHS3 compliance, consistent with the original part's environmental certification.

Frequently Asked Questions (FAQ)

Q: Can SEK010M250ST replace SH010M200ST directly on the PCB? A: Yes. The SEK010M250ST maintains identical lead spacing (0.098"), height (0.433"), and mounting type (through hole). The increased diameter (0.248" versus 0.236") results in minimal mechanical impact on typical PCB layouts. The higher voltage rating (250 V) is backward compatible with circuits designed for 200 V operation.

Q: What is the difference between SEK010M200ST and SEK010M250ST? A: Both components are electrically identical (1 µF, ±20% tolerance, 2000 Hrs @ 105°C lifetime) and mechanically equivalent. The primary difference is voltage rating: SEK010M200ST is rated 200 V, while SEK010M250ST is rated 250 V. Selection depends on circuit voltage requirements.

Q: Why does the parameter comparison show different diameters for some parts? A: The SH010M200ST measures 0.236" in diameter, while the substitute parts measure 0.248". This 0.012" difference remains within typical PCB footprint tolerances for through-hole radial components and does not affect functional compatibility.

Q: Is UPW2D010MED (Nichicon) a viable long-term substitute? A: UPW2D010MED provides electrical and mechanical equivalence but carries obsolete product status. For new designs or long-term production runs, active-status parts (SEK series) are preferred to ensure continued supply availability.

Q: What ESR values should be expected for substitute parts? A: SEK010M200ST and SEK010M250ST specify ESR of 199.04 Ω @ 120Hz, nearly identical to the original SH010M200ST at 198.94 Ω. UPW2D010MED and 517D105M250AA6AE3 do not provide ESR specifications, but ripple current ratings (17 mA @ 120 Hz, 27.2 mA @ 10 kHz) are consistent across parts with available data.

Q: Can these parts be used in applications requiring the -25°C minimum operating temperature of the original? A: Yes. All substitute parts specify -40°C minimum operating temperature, which encompasses the original -25°C specification. This provides additional thermal margin for low-temperature operation.
