ECE-P1HA683HA Equivalent & Substitute Parts

Part Overview

The ECE-P1HA683HA is a 68000 µF, 50 V aluminum electrolytic capacitor in radial, can snap-in configuration with 5 leads, manufactured by Panasonic Electronic Components. This component is classified as obsolete, making identification of equivalent substitute parts essential for ongoing system support and component procurement.

The ECE-P1HA683HA is designed for general purpose applications requiring high capacitance values at moderate voltage ratings. Its snap-in mounting configuration and through-hole design integrate into legacy equipment architectures. Due to its obsolete status, direct replacement sourcing requires evaluation of active equivalent alternatives that maintain electrical and mechanical compatibility.

The substitute parts identified below meet all electrical and mechanical criteria, ensuring direct functional replacement without circuit redesign or board modification.

Parameter Comparison

Engineering Selection Recommendations

Both Cornell Dubilier Electronics (CDE) 383LX series parts qualify as electrical and mechanical equivalents to the obsolete Panasonic ECE-P1HA683HA.

383LX683M050B102V: This part maintains full electrical specification alignment, including ESR specification of 11 mOhm @ 120 Hz. Active product status ensures ongoing availability. ROHS3 compliance supports modern procurement requirements. Height dimension of 4.213" (107.00 mm) exceeds the original 4.134" (105.00 mm) by 2 mm, which must be evaluated for clearance in the target application.

383LX683M050B102VS: This part meets all electrical and mechanical criteria with identical dimensional specifications to 383LX683M050B102V. ESR specification is not provided in available documentation. Active product status and ROHS3 compliance are equivalent to 383LX683M050B102V. Height dimension consideration applies identically.

Selection between the two CDE alternatives depends on ESR specification requirements. If ESR specification of 11 mOhm @ 120 Hz is a design requirement, 383LX683M050B102V is the appropriate selection. If ESR specification is not critical, either part is suitable. Both parts require clearance verification for the 2 mm height increase relative to the original ECE-P1HA683HA.

Frequently Asked Questions (FAQ)

Q: Can 383LX683M050B102V and 383LX683M050B102VS be used interchangeably?

A: Both parts meet the electrical and mechanical requirements for substitution. The primary difference is ESR specification availability. 383LX683M050B102V specifies 11 mOhm @ 120 Hz, while 383LX683M050B102VS does not provide ESR data. Selection depends on whether ESR specification is a design requirement for your application.

Q: What is the impact of the 2 mm height difference?

A: The CDE substitute parts measure 4.213" (107.00 mm) in seated height, compared to 4.134" (105.00 mm) for the original ECE-P1HA683HA. This 2 mm increase must be evaluated against available clearance in the target equipment. If clearance is limited, physical fit testing is necessary before production implementation.

Q: Are the CDE parts compatible with the original snap-in mounting configuration?

A: Yes. Both CDE parts use the identical Radial, Can - Snap-In - 5 Lead package configuration and through-hole mounting type. Snap-in mounting compatibility is maintained.

Q: What compliance certifications apply to the substitute parts?

A: Both CDE 383LX series parts are ROHS3 compliant and REACH unaffected. These certifications support modern procurement and environmental compliance requirements.

Q: How do ripple current specifications compare?

A: The original ECE-P1HA683HA specifies 11.98 A @ 10 kHz. CDE substitutes specify 12 A @ 20 kHz. The CDE specification is measured at a higher frequency (20 kHz vs. 10 kHz), which represents a more stringent operating condition. The slight increase in ripple current rating (12 A vs. 11.98 A) at the higher frequency indicates equivalent or superior performance capability.

Q: Is the ±20% capacitance tolerance maintained across all parts?

A: Yes. All three parts specify ±20% tolerance, ensuring consistent capacitance performance across the substitution group.
