Both parts belong to the category of general-purpose aluminum electrolytic capacitors and maintain functional equivalency within the allowed electrical and mechanical specifications for this product class.

Parameter Comparison

Engineering Selection Recommendations

Both the SLP682M016A1P3 and 381LX682M016H012 are Active products manufactured by Cornell Dubilier Electronics and maintain ROHS3 compliance. The core electrical specifications—capacitance, voltage rating, tolerance, and thermal lifetime—are identical, establishing functional equivalency for general-purpose applications.

The 381LX682M016H012 exhibits two parameter variations: a maximum height increase of 2.00 mm (1.063" versus 0.984") and a ripple current rating at 20 kHz of 2.5 A compared to 2.75 A in the original part. These differences must be evaluated within the specific application constraints. If PCB layout accommodates the additional height and the high-frequency ripple current specification is not a limiting design factor, the 381LX682M016H012 provides a direct functional alternative. Both parts maintain identical lead spacing and package footprint characteristics for board-level integration.

Frequently Asked Questions (FAQ)

Q: What makes the 381LX682M016H012 a suitable substitute for the SLP682M016A1P3? A: Both parts share identical capacitance (6800 µF), voltage rating (16 V), tolerance (±20%), thermal lifetime (3000 hrs @ 105°C), operating temperature range, and package configuration (radial snap-in, through-hole). These core parameters define substitution compatibility for aluminum electrolytic capacitors in this category.

Q: How do the height differences affect PCB layout? A: The 381LX682M016H012 has a maximum seated height of 1.063" compared to 0.984" for the SLP682M016A1P3, a difference of 0.079" (2.00 mm). This difference must be accommodated in PCB clearance and enclosure design but does not affect electrical performance.

Q: What is the significance of the ripple current difference at 20 kHz? A: The SLP682M016A1P3 supports 2.75 A ripple current at 20 kHz, while the 381LX682M016H012 supports 2.5 A. For applications where high-frequency ripple current is a design constraint, this 0.25 A difference requires evaluation against actual circuit requirements.

Q: Do both parts maintain the same PCB footprint? A: Yes. Both parts have identical lead spacing (0.394" / 10.00 mm) and diameter (0.866" / 22.00 mm), ensuring compatible board-level placement without PCB redesign.

Q: Are there any compliance or regulatory considerations when substituting between these parts? A: Both parts are ROHS3 compliant and maintain REACH Unaffected status, meeting equivalent regulatory requirements for general-purpose applications.
