C650-260-WH Equivalent & Substitute Parts

Part Overview

The C650-260-WH is an active surge suppressor from Bourns Inc.'s TBU® series, designed for circuit protection applications. This Surface Mount Device (SMD) component operates at 300V working voltage with 260mA surge suppression capability and 650V impulse rating. The part is ROHS3 compliant and currently in active production status with 18,300 units available in inventory. Substitute parts are identified when equivalent functional performance can be maintained within the allowed electrical and mechanical parameters of this product category.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the C650-260-WH is determined by the following critical parameters:

• Working voltage: 300V (must match)
• Impulse voltage rating: 650V (must match)
• Technology: Internal Switch (must match)
• Number of circuits: 1 (must match)
• Mounting type: Surface Mount (must match)
• Series: TBU® (must match)
• RoHS compliance: ROHS3 Compliant (must match)

The substitute part TBU-CA065-300-WH meets all these criteria. While the current rating differs (300mA vs. 260mA), this represents a higher capacity rating within the same functional class, maintaining compatibility with the specified electrical parameters.

Parameter Comparison

Engineering Selection Recommendations

Both the C650-260-WH and TBU-CA065-300-WH are active production components from Bourns Inc. with identical ROHS3 and REACH compliance certifications. Selection between these parts should be based on:

• Circuit board layout constraints: The C650-260-WH uses a 3-SMD No Lead package, while the TBU-CA065-300-WH uses a larger 6.50mm x 4.00mm SMD package. Physical space availability on the PCB determines which package is suitable.
• Current capacity requirements: The TBU-CA065-300-WH provides 300mA capacity compared to 260mA for the C650-260-WH. Applications requiring higher surge current handling should specify the TBU-CA065-300-WH.
• Packaging format: The C650-260-WH is supplied in Tape & Reel format, while the TBU-CA065-300-WH is available in Cut Tape and Digi-Reel® formats. Production volume and assembly line compatibility determine the appropriate packaging selection.

Frequently Asked Questions (FAQ)

Q: Can TBU-CA065-300-WH replace C650-260-WH in all applications?

A: Substitution is valid when circuit board layout accommodates the larger 6.50mm x 4.00mm package footprint and the application does not require the smaller 3-SMD No Lead form factor. Both parts maintain identical working voltage (300V), impulse rating (650V), and internal switch technology.

Q: What is the difference in current rating between these parts?

A: The C650-260-WH is rated for 260mA surge suppression, while the TBU-CA065-300-WH is rated for 300mA. The higher rating of the substitute part does not create incompatibility; it represents increased capacity within the same voltage class.

Q: Are there packaging considerations for automated assembly?

A: Yes. The C650-260-WH comes in Tape & Reel (TR) packaging, optimized for high-volume automated pick-and-place assembly. The TBU-CA065-300-WH is available in Cut Tape (CT) and Digi-Reel® formats, which may require different feeder configurations on assembly equipment.

Q: Do both parts meet the same compliance standards?

A: Both parts are ROHS3 compliant and REACH unaffected, meeting identical environmental and regulatory requirements. No compliance differences exist between the two components.

Q: What determines whether these parts are interchangeable?

A: Interchangeability is determined by matching working voltage (300V), impulse rating (650V), internal switch technology, single circuit configuration, and surface mount mounting type. Package footprint compatibility with the PCB design is the primary physical constraint.
