PI2003-00-SOIG Equivalent & Substitute Parts

Part Overview

The PI2003-00-SOIG is an N+1 ORing Controller manufactured by Vicor Corporation, designed for power management applications in N+1 power supplies and telecom/datacom systems. This component functions as an OR controller for N-channel FETs in N:1 input-to-output configurations without internal switching capability.

The PI2003-00-SOIG is classified as obsolete. Identifying suitable substitute components is necessary to maintain system continuity and ensure design flexibility for new implementations or legacy system replacements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PI2003-00-SOIG is determined by the following critical parameters:

• Functional Type: N+1 Oring Controller with N-channel FET architecture
• Input:Output Ratio: N:1 configuration
• Internal Switching: No internal switches required
• Package Compatibility: 8-SOIC form factor with 0.154" (3.90mm) width
• Mounting Type: Surface mount technology
• Electrical Interface: Compatible supply voltage and operating temperature ranges for target application

The TPS2413D from Texas Instruments meets these core substitution criteria, sharing identical functional classification, FET type, ratio configuration, package form factor, and mounting methodology.

Parameter Comparison

Engineering Selection Recommendations

The TPS2413D is an active product from Texas Instruments with current manufacturing support and availability. Both components share identical package geometry, mounting methodology, and core functional architecture, enabling direct substitution at the board layout level.

Key considerations for component selection:

• Product Status: The PI2003-00-SOIG is obsolete; the TPS2413D is active and supported
• Compliance: Both components are ROHS3 compliant and REACH unaffected
• Supply Voltage Range: The PI2003-00-SOIG operates at -48V; the TPS2413D operates within 3V ~ 16.5V. Voltage compatibility must be verified for the target application
• Operating Temperature: The PI2003-00-SOIG supports -40°C ~ 125°C; the TPS2413D supports -40°C ~ 85°C. Temperature range requirements must be confirmed
• Supply Current: The TPS2413D draws 4.25 mA versus 1.5 mA for the PI2003-00-SOIG, affecting power budget calculations
• OFF Delay Time: The TPS2413D exhibits 130 ns delay versus 160 ns, representing a 19% improvement in switching response

Frequently Asked Questions (FAQ)

Q: Can the TPS2413D directly replace the PI2003-00-SOIG in existing designs?

A: Direct PCB-level replacement is possible due to identical 8-SOIC packaging and pin configuration. However, electrical parameter differences—particularly supply voltage range, operating temperature limits, and supply current—must be validated against application requirements before implementation.

Q: What are the primary electrical differences between these components?

A: The PI2003-00-SOIG is specified for -48V supply operation with 1.5 mA quiescent current and 160 ns OFF delay time. The TPS2413D operates within 3V ~ 16.5V with 4.25 mA supply current and 130 ns OFF delay time. These differences affect power supply design, thermal management, and switching performance.

Q: Are both components suitable for telecom/datacom applications?

A: The PI2003-00-SOIG is explicitly rated for telecom/datacom systems and N+1 power supplies. The TPS2413D is rated for N+1 power supplies and high availability applications. Application-specific requirements must determine suitability.

Q: What is the temperature operating range difference?

A: The PI2003-00-SOIG supports -40°C ~ 125°C operation. The TPS2413D supports -40°C ~ 85°C. Applications requiring operation above 85°C cannot use the TPS2413D as a substitute.

Q: Are there any compliance or regulatory differences?

A: Both components are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99. No regulatory differentiation exists between these components.

Q: What packaging options are available for the TPS2413D?

A: The TPS2413D is supplied in tube packaging. The PI2003-00-SOIG packaging specification was not provided in the source data.
