Panasonic EEF-HE0D331R Equivalent & Substitute Parts

Part Overview

The Panasonic EEF-HE0D331R is a 330 µF, 2 V aluminum polymer surface mount capacitor in the 2917 (7343 Metric) package. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and production continuity. The part is designed for general purpose applications requiring low ESR characteristics in compact form factors.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the EEF-HE0D331R is determined by the following critical parameters:

• Capacitance Value: 330 µF (exact match required)
• Voltage Rating: Minimum 2 V (equal or higher voltage ratings are acceptable)
• Package / Case: 2917 (7343 Metric) (physical compatibility required)
• Mounting Type: Surface Mount (must match)
• Type: Aluminum Polymer (technology class must match)
• Tolerance: ±20% (standard tolerance for this category)

Two substitute parts meet these criteria with variations in voltage rating, ESR, and product status.

Parameter Comparison

Engineering Selection Recommendations

EEF-HX0E331R9 (Panasonic SP-Cap HX Series)

This substitute offers the same manufacturer lineage as the original part. The 2.5 V voltage rating exceeds the 2 V requirement, providing design margin. The lower ESR (9 mOhm versus 12 mOhm) and higher ripple current capability (6.3 A versus 3 A) represent performance improvements. The part is active in production with RoHS3 compliance and extended operating temperature range (-55°C to 125°C). Packaging is Tape & Reel (TR).

A700D337M002ATE012 (KEMET AO-Cap A700 Series)

This substitute maintains identical electrical specifications to the original part (2 V rating, 12 mOhm ESR). The KEMET part is active in production with RoHS3 compliance and extended operating temperature range (-55°C to 125°C). The higher ripple current (4.6 A versus 3 A) provides operational headroom. Packaging is Tape & Reel (TR). This option is suitable for designs requiring exact electrical parameter matching with the original part.

Frequently Asked Questions (FAQ)

Q: Can the EEF-HX0E331R9 be used as a direct replacement for the EEF-HE0D331R?

A: Yes. Both parts share identical capacitance (330 µF), tolerance (±20%), package (2917 Metric), and mounting type (Surface Mount). The EEF-HX0E331R9 operates at 2.5 V, which exceeds the 2 V requirement of the original part, making it electrically compatible. The lower ESR and higher ripple current are performance enhancements.

Q: What is the difference between the two substitute options?

A: The EEF-HX0E331R9 offers a higher voltage rating (2.5 V) with improved ESR and ripple current specifications. The A700D337M002ATE012 maintains the exact 2 V voltage rating and 12 mOhm ESR of the original part. Both are active production parts with RoHS3 compliance.

Q: Are there physical dimension differences between these parts?

A: All three parts use the 2917 (7343 Metric) package with identical surface mount land sizes (0.287" L x 0.169" W). Seated heights vary: EEF-HE0D331R at 0.169" (4.30mm), EEF-HX0E331R9 at 0.079" (2.00mm), and A700D337M002ATE012 at 0.122" (3.10mm). Verify PCB clearance for the specific substitute selected.

Q: Which substitute should I select for new designs?

A: Both substitutes are active production parts with RoHS3 compliance. The EEF-HX0E331R9 is recommended for designs benefiting from lower ESR and higher ripple current. The A700D337M002ATE012 is recommended for designs requiring exact electrical parameter matching with the original specification.

Q: Are these parts available in different packaging formats?

A: Both substitute parts are supplied in Tape & Reel (TR) packaging. The original EEF-HE0D331R packaging format is not specified in the available data.
