CD214B-T8.0CALF Equivalent & Substitute Parts

Part Overview

The CD214B-T8.0CALF is a transient voltage suppressor (TVS) diode manufactured by Bourns Inc., designed for general-purpose overvoltage protection in surface-mount applications. This component features an 8V reverse standoff voltage with a 13.6V maximum clamping voltage and 44.1A peak pulse current capability in the DO-214AA (SMB) package. The part is currently obsolete, making equivalent substitute parts necessary for new designs and ongoing production requirements.

Frequently Asked Questions (FAQ)

Q: Can I use any of these substitute parts as a direct replacement for CD214B-T8.0CALF?

A: Yes. All listed substitute parts maintain identical electrical specifications (8V reverse standoff, 13.6V clamping voltage, 44.1A to 44.2A peak pulse current) and are packaged in the same DO-214AA (SMB) surface-mount configuration. They are pin-compatible and functionally equivalent for general-purpose transient voltage suppression applications.

Q: What is the difference between the substitute parts?

A: The primary differences are manufacturer, product status (all active), and operating temperature ranges. SMBJ8.0CA-TP offers the widest temperature range (-55°C to 175°C), while SMBJ8V0CA has the highest inventory availability (4300 units). All parts meet ROHS3 compliance and MSL 1 requirements.

Q: Does the DO-214AA (SMB) package remain the same across all substitutes?

A: Yes. All substitute parts use the DO-214AA (SMB) surface-mount package, ensuring mechanical and electrical compatibility with existing PCB layouts designed for the CD214B-T8.0CALF.

Q: Are there any compliance or certification differences I should consider?

A: All substitute parts are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity ratings, matching the original part's compliance profile. REACH status varies by manufacturer but does not affect functional substitution.

Q: Which substitute part should I select for new designs?

A: Selection depends on application requirements. For standard temperature ranges (-55°C to 150°C), SMBJ8V0CA offers the best inventory availability. For extended temperature applications, SMBJ8.0CA-TP supports -55°C to 175°C operation. All parts are electrically and mechanically equivalent.
