Key Parameters

Substitute Part Grouping Explanation

The P850-G200-WH qualifies as a substitute for the P500-G200-WH based on the following alignment of critical parameters:

• Series Compatibility: Both components belong to the TBU® series from Bourns Inc., ensuring consistent internal switch technology and operational characteristics
• Current Rating: Both parts maintain the same 200MA current specification
• Number of Circuits: Both feature dual-circuit configuration (2 circuits)
• Technology: Both utilize internal switch technology for circuit protection
• Mounting Type: Both are surface mount components
• Package Type: Both use 6-SMD, No Lead packages suitable for identical PCB footprints
• Compliance Standards: Both maintain ROHS3 compliance and REACH unaffected status
• MSL Rating: Both share MSL 3 (168 Hours) moisture sensitivity classification

The primary difference lies in voltage specifications: the P850-G200-WH operates at 425V working voltage with 850V impulse rating, compared to the P500-G200-WH's 300V working voltage with 500V impulse rating. This represents an upgrade in voltage handling capability.

Parameter Comparison

Engineering Selection Recommendations

The P850-G200-WH is the designated substitute for the obsolete P500-G200-WH. Selection of this substitute is supported by:

• Product Status: The P850-G200-WH maintains active product status with current manufacturing and supply chain availability, whereas the P500-G200-WH is obsolete
• Regulatory Compliance: Both components maintain identical ROHS3 compliance and REACH unaffected status, ensuring no regulatory barriers to substitution
• Functional Equivalence: Matching current rating, circuit count, technology platform, and package configuration ensure direct PCB compatibility and functional performance in SLIC applications
• Enhanced Specifications: The higher voltage rating of the P850-G200-WH (425V working, 850V impulse) provides improved protection margin in applications operating within the original 300V specification

Frequently Asked Questions (FAQ)

Q: Can the P850-G200-WH be used as a direct replacement for the P500-G200-WH?

A: Yes. Both components share identical current ratings (200MA), circuit count (2), mounting type (surface mount), and package configuration (6-SMD, No Lead). The higher voltage specification of the P850-G200-WH does not prevent substitution in applications designed for the lower voltage rating.

Q: What is the primary difference between these two parts?

A: The P850-G200-WH operates at 425V working voltage with 850V impulse rating, while the P500-G200-WH operates at 300V working voltage with 500V impulse rating. The P850-G200-WH provides enhanced voltage protection capability.

Q: Are there any package or footprint differences?

A: Both components use 6-SMD, No Lead packages. However, the supplier device packages differ slightly: P500-G200-WH uses 6-DFN (4x6), while P850-G200-WH uses 10-DFN (4x8.25). Verify PCB layout compatibility with your specific design requirements.

Q: What is the product status of each part?

A: The P500-G200-WH is classified as obsolete, while the P850-G200-WH maintains active product status with current manufacturing support and inventory availability.

Q: Do both parts meet the same compliance standards?

A: Yes. Both components are ROHS3 compliant, REACH unaffected, and share identical MSL 3 (168 Hours) moisture sensitivity ratings.
