Parameter Comparison

Engineering Selection Recommendations

Both the 339LBB016M2DF and SLPX333M016E7P3 are active production parts with full ROHS3 compliance and REACH unaffected status, making either suitable for new designs and existing applications. The SLPX333M016E7P3 substitute offers lower ESR and improved ripple current performance while maintaining identical electrical ratings and mechanical form factor. The main part 339LBB016M2DF remains the primary choice when existing inventory or specific series designation is required. The substitute part is electrically and mechanically interchangeable for through-hole PCB applications requiring 33000 µF capacitance at 16 V with snap-in mounting.

Frequently Asked Questions (FAQ)

Q: Can the SLPX333M016E7P3 be used as a direct replacement for the 339LBB016M2DF?

A: Yes. Both parts share identical capacitance (33000 µF), voltage rating (16 V), tolerance (±20%), lifetime (3000 Hrs @ 85°C), operating temperature range (-40°C to 85°C), lead spacing (10.00 mm), diameter (30.00 mm), and package type (Radial, Can - Snap-In). The substitute exhibits improved ESR and ripple current specifications.

Q: Are there any physical compatibility concerns?

A: The substitute part has a maximum seated height of 1.575" (40.00 mm) compared to 1.654" (42.00 mm) for the main part. This 0.079" (2.00 mm) difference represents a reduction in height, which is compatible with existing PCB layouts designed for the main part.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the 339LBB016M2DF and SLPX333M016E7P3 are ROHS3 Compliant, REACH Unaffected, and carry ECCN classification EAR99.

Q: What is the difference in ESR between these parts?

A: The main part 339LBB016M2DF has an ESR of 25.12 mOhm @ 120Hz, while the substitute SLPX333M016E7P3 has an ESR of 20 mOhm @ 120Hz. Lower ESR in the substitute part results in reduced heat generation and improved performance in ripple current applications.

Q: Are the ripple current ratings equivalent?

A: The ripple current ratings differ slightly. At 120 Hz, the main part handles 5.36 A while the substitute handles 5.6 A. At high frequency, the main part handles 6.7 A @ 10 kHz and the substitute handles 7 A @ 20 kHz. Both specifications are suitable for general-purpose applications.

Q: Can these parts be used interchangeably in existing designs?

A: Yes. The identical electrical specifications, lead spacing, diameter, and package type ensure mechanical and electrical interchangeability in through-hole PCB applications. The reduced height of the substitute part is compatible with existing layouts.
