VN340SP Equivalent & Substitute Parts

Part Overview

The VN340SP is a Power Management Integrated Circuit (PMIC) manufactured by STMicroelectronics, classified as a Power Switch/Driver with 1:1 N-Channel configuration. This component functions as a general-purpose power driver capable of delivering 700mA output current in a high-side configuration with on/off interface control. The VN340SP is designated as obsolete product status, necessitating identification of active equivalent alternatives for new designs and ongoing production requirements. Substitute parts maintain identical electrical and mechanical specifications while offering active product status and improved availability.

Parameter Comparison

Engineering Selection Recommendations

VN340SP-E is the direct active equivalent of the obsolete VN340SP. Both parts share identical base product number (VN340) and maintain complete parametric equivalence across all electrical and mechanical specifications. The VN340SP-E carries active product status with ROHS3 compliance and REACH unaffected certification. This part is the primary selection for direct replacement in new designs and production continuity.

VN330SP-E is a parametric equivalent alternative based on identical electrical performance and mechanical packaging. The VN330SP-E differs only in base product number (VN330 versus VN340) while maintaining all critical functional parameters including output configuration, current rating, voltage range, and thermal characteristics. This part carries active product status with ROHS3 compliance and REACH unaffected certification. The VN330SP-E is suitable for applications where the VN340SP-E is unavailable.

Both substitute parts are manufactured by STMicroelectronics and are available in active product status, ensuring long-term supply continuity and technical support. Selection between VN340SP-E and VN330SP-E should be based on availability and supply chain requirements, as both provide identical functional performance in PowerSO-10 surface mount applications.

Frequently Asked Questions (FAQ)

Q: Can VN340SP-E directly replace VN340SP in existing circuit designs?

A: Yes. The VN340SP-E maintains complete parametric equivalence with the obsolete VN340SP across all electrical specifications (output configuration, current rating, voltage range, operating temperature) and mechanical packaging (PowerSO-10 Exposed Bottom Pad, surface mount). No circuit modifications are required for direct substitution.

Q: What is the difference between VN340SP-E and VN330SP-E?

A: Both parts are parametric equivalents with identical electrical performance and mechanical packaging. The primary difference is the base product number (VN340 versus VN330). All critical functional parameters including 700mA output current, 10V ~ 36V load voltage, 200mOhm Rds On, and PowerSO-10 packaging are identical. Selection should be based on availability and supply chain considerations.

Q: Are the substitute parts RoHS and REACH compliant?

A: Yes. Both VN340SP-E and VN330SP-E are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic components.

Q: What is the moisture sensitivity level difference between the original and substitute parts?

A: The VN340SP has MSL 1 (Unlimited), while both VN340SP-E and VN330SP-E have MSL 3 (168 Hours). MSL 3 requires storage in controlled humidity conditions (not exceeding 60% relative humidity) for up to 168 hours before soldering. Standard moisture control procedures during component handling and assembly are required.

Q: Are both substitute parts available in the same packaging format?

A: Both VN340SP-E and VN330SP-E are supplied in Tube packaging, which differs from the original VN340SP packaging specification. Both maintain identical PowerSO-10 Exposed Bottom Pad component packaging for circuit board assembly.

Q: Can I use VN330SP-E if VN340SP-E is unavailable?

A: Yes. The VN330SP-E provides identical electrical performance and mechanical compatibility. Both parts are suitable for applications requiring 700mA N-Channel high-side power switching with on/off control in the 10V ~ 36V load voltage range.

Q: What are the key parameters that make these parts interchangeable?

A: Interchangeability is determined by: 4-output high-side N-Channel configuration, 1:1 input-output ratio, 700mA maximum output current, 200mOhm maximum Rds On, 10V ~ 36V load voltage range, -40°C ~ 125°C operating temperature, on/off interface with non-inverting input, status flag feature, current limiting and over-temperature fault protection, and PowerSO-10 Exposed Bottom Pad surface mount packaging.
