EEF-LT0D331R Equivalent & Substitute Parts

Part Overview

The EEF-LT0D331R is a 330 µF, 2 V aluminum polymer surface mount capacitor manufactured by Panasonic Electronic Components. This component is part of the SP-Cap LT series and is actively produced. The capacitor is designed for general purpose applications requiring low equivalent series resistance and stable performance across extended temperature ranges. Substitute parts may be required due to inventory availability, supply chain considerations, or design flexibility within equivalent electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitution of the EEF-LT0D331R is permissible with parts that maintain identical electrical and mechanical specifications. The critical parameters governing substitution are:

• Capacitance: 330 µF (exact match required)
• Voltage Rating: 2 V (exact match required)
• Tolerance: ±20% (exact match required)
• Type: Polymer (exact match required)
• ESR: 6 mOhm (exact match required)
• Lifetime: 2000 Hrs @ 105°C (exact match required)
• Operating Temperature: -55°C ~ 105°C (exact match required)
• Ripple Current: 7.5 A @ 100 kHz (exact match required)
• Package: 2917 (7343 Metric) (exact match required)
• Mounting Type: Surface Mount (exact match required)
• Physical Dimensions: 0.287" L x 0.169" W x 0.059" H max (exact match required)

The EEF-ST0D331R qualifies as a parametric equivalent substitute, differing only in the internal series designation (SP-Cap ST versus SP-Cap LT) while maintaining all electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

Both the EEF-LT0D331R and EEF-ST0D331R are active products manufactured by Panasonic Electronic Components and maintain full compliance with ROHS3 and REACH regulations. Selection between these parts may be based on inventory availability and supply chain logistics, as both components satisfy identical electrical performance requirements and mechanical constraints. The EEF-ST0D331R currently maintains higher inventory levels (10,314 pieces) compared to the EEF-LT0D331R (871 pieces), which may influence procurement decisions for high-volume applications.

Frequently Asked Questions (FAQ)

Q: Can the EEF-ST0D331R be used as a direct replacement for the EEF-LT0D331R?

A: Yes. The EEF-ST0D331R is a parametric equivalent substitute. All electrical specifications (capacitance, voltage rating, ESR, ripple current, lifetime) and mechanical specifications (package, dimensions, mounting type) are identical. The difference lies only in the internal series designation within Panasonic's product line.

Q: Are there any differences in PCB layout or footprint requirements?

A: No. Both parts use the identical 2917 (7343 Metric) package with matching surface mount land sizes of 0.287" L x 0.169" W (7.30 mm x 4.30 mm). PCB layouts and footprints are interchangeable.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the EEF-LT0D331R and EEF-ST0D331R are ROHS3 compliant and REACH unaffected, meeting equivalent regulatory requirements.

Q: What is the significance of the series designation (LT versus ST)?

A: The series designation indicates the internal product line classification within Panasonic's SP-Cap polymer capacitor portfolio. Both LT and ST series maintain identical electrical and mechanical performance for this specific part number configuration.

Q: Are there any temperature or ripple current performance differences?

A: No. Both parts operate across the identical temperature range (-55°C ~ 105°C) and support the same ripple current specification (7.5 A @ 100 kHz). Thermal and frequency performance characteristics are equivalent.
