Frequently Asked Questions (FAQ)

Q1: Can the SEK100M200ST (200 V rating) be used as a direct replacement for the SH100M160ST (160 V rating)?

A: Yes. The SEK100M200ST is electrically compatible as a substitute. The higher voltage rating (200 V) provides additional design margin and does not compromise circuit function in 160 V applications. The capacitance (10 µF), tolerance (±20%), and lead spacing (5.00 mm) are identical. Verify PCB layout accommodates the 13.00 mm height (0.50 mm taller than original). The higher voltage rating is an advantage in applications subject to voltage transients or where design margin is beneficial.

Q2: What is the significance of the height difference between substitute parts?

A: Physical height differences (ranging from 12.00 mm to 13.50 mm) affect PCB layout clearance and component density. The SH100M160ST specifies 12.00 mm maximum height. Substitutes with heights up to 12.50 mm (517D106M160CC6AE3, UPW2C100MPD) require minimal layout adjustment. The ECA-2CHG100 at 13.50 mm and SEK100M200ST at 13.00 mm require verification of vertical clearance above the component. If PCB layout includes conformal coating, potting, or adjacent tall components, height variation may necessitate design modification. Measure available clearance before component selection.

Q3: Why is product status (Active versus Obsolete) important in substitute selection?

A: Product status indicates manufacturing continuity and supply chain availability. Active products (ECA-2CHG100, SEK100M200ST) are currently manufactured and available through authorized distributors, supporting ongoing production and future reorders. Obsolete products (SH100M160ST, 517D106M160CC6AE3, UPW2C100MPD) are discontinued and available only from remaining inventory; supply is limited and unpredictable. For new designs or production quantities exceeding current inventory, Active products are mandatory. For repair or limited-quantity applications, Obsolete substitutes may be acceptable if inventory is confirmed available.

Q4: Are all substitute parts RoHS compliant?

A: Yes. All substitute parts listed (517D106M160CC6AE3, ECA-2CHG100, UPW2C100MPD, SEK100M200ST) are ROHS3 Compliant. This ensures compatibility with regulatory requirements in electronics manufacturing and end-use markets. RoHS compliance is maintained across all substitute options.

Q5: What does ESR (Equivalent Series Resistance) indicate, and why is it important?

A: ESR represents the internal resistance of the capacitor at a specified frequency (typically 120 Hz or 10 kHz). Lower ESR values indicate better performance in ripple current applications and reduced heat generation. The SH100M160ST specifies 19.89 Ohm @ 120 Hz. The SEK100M200ST matches this specification at 19.9 Ohm. Other substitutes do not provide ESR data; however, they maintain equivalent ripple current ratings (70 mA @ 120 Hz, 112 mA @ 10 kHz), indicating acceptable ESR performance. ESR becomes critical in high-frequency switching applications or where thermal management is constrained.

Q6: Can substitutes with extended lifetime (5000 hours) be used in place of 2000-hour parts?

A: Yes. The UPW2C100MPD offers 5000-hour lifetime @ 105°C, compared to the SH100M160ST's 2000-hour specification. Extended lifetime is a performance upgrade and does not compromise compatibility. This substitution is beneficial in applications requiring enhanced reliability or extended service intervals. However, the UPW2C100MPD carries Obsolete product status, limiting availability.

Q7: What is the operating temperature range significance?

A: The SH100M160ST operates from -25°C to 105°C. Substitutes offer extended lower-temperature performance: 517D106M160CC6AE3, UPW2C100MPD, and SEK100M200ST all operate from -40°C to 105°C. This extended range is beneficial in applications subject to cold environments or thermal cycling. The ECA-2CHG100 matches the original -25°C to 105°C range. For applications operating within -25°C to 105°C, all substitutes are acceptable. For applications requiring -40°C operation, select 517D106M160CC6AE3, UPW2C100MPD, or SEK100M200ST.

Q8: Are there any mechanical compatibility issues with through-hole mounting?

A: All substitute parts maintain identical lead spacing (5.00 mm / 0.197 inches) and diameter (10.00 mm), ensuring direct PCB footprint compatibility. No modifications to PCB drilling or trace routing are required. Height variations (12.00 mm to 13.50 mm) may affect vertical clearance but do not impact electrical connectivity or soldering process. Verify clearance above component before final assembly.

Q9: Which substitute offers the best overall compatibility?

A: The ECA-2CHG100 (Panasonic) provides the best overall compatibility: Active product status ensures supply continuity, identical electrical specifications (10 µF, 160 V, ±20%), matching lead spacing and diameter, equivalent ripple current performance, and ROHS3 compliance. The 13.50 mm height requires PCB clearance verification but is the only minor consideration. For applications prioritizing supply chain reliability and long-term availability, ECA-2CHG100 is the recommended primary choice.

Q10: Can multiple substitute parts be used interchangeably in the same design?

A: Yes, provided all parts meet the circuit's electrical requirements. However, for production consistency and supply chain management, selecting a single primary substitute is recommended. If multiple substitutes are used, document the approved parts list and ensure all variants are tested and validated for the specific application. Height variations between parts may require separate PCB layout verification for each substitute.
