C650-100-WH Equivalent & Substitute Parts

Part Overview

The C650-100-WH is a 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 100mA surge suppression capability and 650V impulse voltage rating. The part is currently Active in product status and maintains full RoHS3 compliance. Substitute parts are identified when packaging format or inventory availability requires alternative sourcing while maintaining equivalent electrical and mechanical performance.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the C650-100-WH is determined by the following critical parameters:

• Voltage - Working: 300V (must match exactly)
• Voltage - Clamping: 650V (must match exactly)
• Current Rating: 100mA (must match exactly)
• Technology: Internal Switch (must match exactly)
• Number of Circuits: 1 (must match exactly)
• Series: TBU® (must match exactly)
• Mounting Type: Surface Mount (must match exactly)
• Applications: General Purpose (must match exactly)
• RoHS Status: ROHS3 Compliant (must match exactly)

The substitute part TBU-CA065-100-WH meets all critical electrical parameters and maintains identical functional specifications. The primary difference is packaging format: the main part uses Tape & Reel (TR) in a 3-SMD, No Lead package, while the substitute uses Cut Tape (CT) & Digi-Reel® in an SMD 6.50mm x 4.00mm package format.

Parameter Comparison

Engineering Selection Recommendations

Both C650-100-WH and TBU-CA065-100-WH are Active products from Bourns Inc. with full ROHS3 compliance and REACH Unaffected status. Selection between these parts is based on packaging and logistics requirements rather than electrical performance.

The C650-100-WH in Tape & Reel format is suitable for high-volume automated assembly operations. The TBU-CA065-100-WH in Cut Tape & Digi-Reel® format provides flexibility for lower-volume applications or mixed component sourcing scenarios. The substitute part offers superior moisture handling with MSL 1 (Unlimited) compared to MSL 3 (168 Hours) for the main part, providing extended shelf life and reduced storage constraints.

Both parts satisfy identical electrical specifications for 300V working voltage, 100mA surge suppression, and 650V impulse protection in general-purpose circuit protection applications.

Frequently Asked Questions (FAQ)

Q: Can TBU-CA065-100-WH replace C650-100-WH in production assembly?

A: Yes. Both parts are electrically and functionally equivalent. The substitute operates at identical voltage and current specifications. Packaging format differences (Tape & Reel versus Cut Tape & Digi-Reel®) affect handling and assembly logistics but not component performance.

Q: What is the difference in package dimensions?

A: The C650-100-WH uses a 3-SMD, No Lead package format. The TBU-CA065-100-WH uses an SMD 6.50mm x 4.00mm package format. Both are Surface Mount devices suitable for automated placement equipment. Physical footprint compatibility must be verified against PCB design specifications.

Q: Does the moisture sensitivity difference affect component selection?

A: The TBU-CA065-100-WH has MSL 1 (Unlimited) compared to C650-100-WH MSL 3 (168 Hours). This means the substitute part has no moisture sensitivity restrictions and extended shelf life. For applications with extended storage or humid environments, the substitute offers operational advantages.

Q: Are both parts RoHS3 compliant?

A: Yes. Both C650-100-WH and TBU-CA065-100-WH are ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory requirements.

Q: Which part should be selected for new designs?

A: Both parts are Active products suitable for new designs. Selection depends on procurement availability, packaging format requirements, and assembly process specifications. The substitute part's superior moisture handling (MSL 1) may provide advantages for long-term inventory management.
