Substitute Part Grouping Explanation

Substitution of the ECE-A1EKA4R7 is determined by the following criteria:

Upgrade Substitutes maintain identical capacitance (4.7 µF), tolerance (±20%), and physical dimensions while providing higher voltage ratings or improved thermal performance:

• ECE-A1HKA4R7: Increases rated voltage to 50 V while maintaining identical physical footprint and 1000-hour lifetime at 85°C
• ECE-A1VKA4R7: Increases rated voltage to 35 V while maintaining identical physical footprint and 1000-hour lifetime at 85°C
• EEA-GA1H4R7: Increases rated voltage to 50 V and extends operating temperature range to -55°C ~ 105°C with 1000-hour lifetime at 105°C

Similar Substitute maintains identical electrical specifications (4.7 µF, ±20%, 25 V) with minor physical variation:

• ECE-A1EKS4R7: Same capacitance, tolerance, and voltage rating; differs in series designation (KS vs. KA) and seated height (0.236" vs. 0.276")

All substitutes maintain through-hole radial mounting, 0.059" lead spacing, and 0.157" diameter can size. All are ROHS3 compliant and rated for general-purpose applications.

Parameter Comparison

Engineering Selection Recommendations

All listed substitutes maintain active product status and ROHS3 compliance, ensuring long-term availability and regulatory conformance.

For applications requiring higher voltage margin: ECE-A1HKA4R7 and EEA-GA1H4R7 both provide 50 V rating while maintaining the same 4.7 µF capacitance and physical footprint as the original part. Both are suitable direct replacements in circuits where the original 25 V rating provides insufficient safety margin.

For applications requiring extended thermal performance: EEA-GA1H4R7 extends the operating temperature range to -55°C ~ 105°C and provides 1000-hour lifetime at 105°C, compared to the original part's 85°C maximum. This substitute is appropriate for high-temperature environments or applications requiring enhanced reliability at elevated temperatures.

For applications with intermediate voltage requirements: ECE-A1VKA4R7 provides a 35 V rating, positioned between the original 25 V and the 50 V options, while maintaining identical physical dimensions and thermal characteristics.

For space-constrained applications: ECE-A1EKS4R7 reduces seated height to 0.236" compared to the original 0.276", maintaining identical electrical specifications and voltage rating. This substitute is applicable only when the reduced height does not conflict with circuit board layout requirements.

Frequently Asked Questions (FAQ)

Q: Can ECE-A1HKA4R7 be used as a direct replacement for ECE-A1EKA4R7?

A: Yes. Both parts share identical capacitance (4.7 µF), tolerance (±20%), physical dimensions (0.157" diameter, 0.276" height, 0.059" lead spacing), and mounting type (through-hole radial). The ECE-A1HKA4R7 provides higher voltage rating (50 V vs. 25 V), making it suitable for direct substitution in any application designed for the original part.

Q: What is the difference between ECE-A1HKA4R7 and EEA-GA1H4R7?

A: Both provide 4.7 µF capacitance and 50 V rating with identical physical footprint. The primary difference is thermal performance: EEA-GA1H4R7 operates across -55°C ~ 105°C with 1000-hour lifetime at 105°C, while ECE-A1HKA4R7 operates across -40°C ~ 85°C with 1000-hour lifetime at 85°C. Select EEA-GA1H4R7 for high-temperature applications; select ECE-A1HKA4R7 for standard temperature environments.

Q: Is ECE-A1EKS4R7 compatible with the original ECE-A1EKA4R7?

A: ECE-A1EKS4R7 maintains identical electrical specifications (4.7 µF, ±20%, 25 V) and physical diameter (0.157"). The seated height differs (0.236" vs. 0.276"), making it compatible only if the reduced height does not conflict with circuit board layout or component clearance requirements.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitutes, including ECE-A1HKA4R7, ECE-A1VKA4R7, EEA-GA1H4R7, and ECE-A1EKS4R7, are ROHS3 compliant and suitable for applications requiring regulatory compliance.

Q: What determines whether a part can substitute for ECE-A1EKA4R7?

A: Substitution is determined by matching capacitance (4.7 µF), tolerance (±20%), physical dimensions (0.157" diameter, 0.059" lead spacing), mounting type (through-hole radial), and polarization (polar). Voltage rating, thermal performance, and series designation may vary based on application requirements.
