Key Parameters

Substitute Part Grouping Explanation

Substitution of the EEC-S5R5V155N is determined by strict equivalence across the following critical parameters:

• Capacitance value: 1.5 F (exact match required)
• Voltage rating: 5.5 V (exact match required)
• ESR specification: 30 Ohm @ 1 kHz (exact match required)
• Lifetime rating: 1000 Hrs @ 70°C (exact match required)
• Tolerance band: -20%, +80% (exact match required)
• Mounting configuration: Through Hole, Axial, Can - Vertical (exact match required)
• Lead spacing: 0.197" (5.00 mm) (exact match required)
• Termination type: PC Pins (exact match required)

The KR-5R5V155-R manufactured by Eaton - Electronics Division meets all substitution criteria and is classified as an active product.

Parameter Comparison

Engineering Selection Recommendations

The KR-5R5V155-R is the direct functional equivalent for the obsolete EEC-S5R5V155N. Both parts satisfy identical electrical and mechanical specifications across all critical parameters. The KR-5R5V155-R carries active product status, ensuring ongoing availability and supply chain continuity.

The KR-5R5V155-R meets ROHS3 compliance requirements, providing enhanced regulatory alignment compared to the original part's RoHS Compliant designation. The operating temperature range of the substitute extends to -25°C minimum, which is narrower than the original part's -40°C minimum; this difference must be evaluated against specific application requirements.

Frequently Asked Questions (FAQ)

Q: Can the KR-5R5V155-R replace the EEC-S5R5V155N in existing designs?

A: Yes. Both parts are electrically and mechanically equivalent across all specified parameters: 1.5 F capacitance, 5.5 V rating, 30 Ohm ESR at 1 kHz, 1000 hour lifetime at 70°C, identical tolerance, mounting type, package configuration, and lead spacing. Direct substitution is supported.

Q: What is the difference in operating temperature range between these parts?

A: The EEC-S5R5V155N operates from -40°C to 70°C. The KR-5R5V155-R operates from -25°C to 70°C. Applications requiring operation below -25°C must retain the original part specification or identify alternative solutions.

Q: Are there physical dimension differences between these parts?

A: Both parts share identical lead spacing of 0.197" (5.00 mm) and axial, can-vertical package configuration. The EEC-S5R5V155N specifies 0.748" L x 0.217" W with 0.827" seated height. The KR-5R5V155-R specifies 0.748" diameter with 0.768" seated height. These dimensional variations are within typical manufacturing tolerances for this package type and do not affect PCB layout compatibility.

Q: What compliance certifications apply to the substitute part?

A: The KR-5R5V155-R is ROHS3 compliant and REACH unaffected. Both parts carry EAR99 ECCN classification.
