Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the CD214B-T160CALF are grouped based on strict electrical and mechanical parameter alignment:

Direct Electrical Equivalents (160V Standoff, 259V Clamp):

• SMBJ160CA (Taiwan Semiconductor Corporation)
• SMBJ160CA-TP (Micro Commercial Co)
• TV06B161JB-HF (Comchip Technology)

These parts maintain identical reverse standoff voltage (160V), breakdown voltage (178V minimum), and clamping voltage (259V maximum) specifications. Peak pulse current ratings are equivalent or superior (2.3A to 2.32A). All are packaged in DO-214AA (SMB) format with surface mount configuration.

Similar Voltage Class Alternatives (170V Standoff, 275V Clamp):

• SMBJ170CA (Meritek)
• SMBJ170CA-HR (Littelfuse Inc.)

These parts operate at a higher voltage class with 170V reverse standoff and 275V clamping voltage. Selection of these alternatives requires circuit-level evaluation to confirm compatibility with the application's voltage protection requirements.

Key Parameters Determining Substitution:

• Reverse standoff voltage (160V or 170V class)
• Maximum clamping voltage (259V or 275V)
• Peak pulse current capability (≥2.18A)
• Package format (DO-214AA/SMB)
• Mounting type (Surface Mount)
• Bidirectional channels (1)
• RoHS3 compliance
• MSL rating (1 - Unlimited)

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (160V Class):

SMBJ160CA, SMBJ160CA-TP, and TV06B161JB-HF are active production alternatives with identical electrical specifications to the obsolete CD214B-T160CALF. All three maintain 160V reverse standoff voltage, 259V clamping voltage, and 2.3A peak pulse current ratings. Selection among these direct equivalents should prioritize:

• Product availability and lead time
• Supplier qualification and quality certifications
• REACH compliance status (SMBJ160CA-TP and TV06B161JB-HF are REACH Unaffected; SMBJ160CA is REACH Unaffected)
• Operating temperature range requirements (SMBJ160CA-TP extends to 175°C versus 150°C for others)

For Higher Voltage Class Applications (170V Class):

SMBJ170CA and SMBJ170CA-HR operate at elevated voltage specifications (170V standoff, 275V clamp). These alternatives are suitable only when circuit design permits operation at the higher voltage class. Both maintain 600W peak pulse power and are ROHS3 compliant. SMBJ170CA-HR provides extended lower temperature rating (-65°C minimum versus -55°C).

Compliance Considerations:

All substitute parts are ROHS3 compliant with MSL rating of 1 (Unlimited), matching the original component's environmental and regulatory status. All are classified as active production components, ensuring long-term supply chain stability compared to the obsolete CD214B-T160CALF.

Frequently Asked Questions (FAQ)

Q: Can SMBJ160CA directly replace CD214B-T160CALF without circuit modification?

A: Yes. SMBJ160CA maintains identical electrical parameters: 160V reverse standoff, 259V clamping voltage, 2.3A peak pulse current, and 600W peak pulse power. Both use DO-214AA (SMB) surface mount packaging. No circuit modification is required for direct substitution.

Q: What is the difference between SMBJ160CA-TP and SMBJ160CA?

A: Both parts share identical electrical specifications (160V standoff, 259V clamp, 2.3A peak pulse). The primary difference is operating temperature range: SMBJ160CA-TP extends to 175°C junction temperature versus 150°C for SMBJ160CA. SMBJ160CA-TP is manufactured by Micro Commercial Co; SMBJ160CA is manufactured by Taiwan Semiconductor Corporation.

Q: Can SMBJ170CA be used as a substitute for CD214B-T160CALF?

A: SMBJ170CA operates at a higher voltage class (170V standoff, 275V clamp versus 160V/259V). Substitution is possible only if the circuit design permits operation at these elevated voltage specifications. Peak pulse current is slightly lower (2.18A versus 2.3A). Circuit-level evaluation is required before selection.

Q: Are all substitute parts available in the same package format?

A: Yes. All substitute parts listed are packaged in DO-214AA (SMB) surface mount format, matching the original CD214B-T160CALF package specification. No PCB layout or footprint modifications are necessary.

Q: What is the significance of the REACH Unaffected status on some parts?

A: REACH Unaffected status indicates the component is not subject to REACH (Registration, Evaluation, Authorization and Restriction of Chemicals) regulatory restrictions. All substitute parts listed carry either REACH Unaffected or REACH Affected status as provided in the specifications. Verify compliance requirements for your specific application and region.

Q: Which substitute part offers the best temperature performance?

A: SMBJ160CA-TP provides the widest operating temperature range (-55°C to 175°C junction temperature), extending 25°C above the original CD214B-T160CALF specification (-55°C to 150°C). SMBJ170CA-HR extends the lower temperature limit to -65°C but maintains the 150°C upper limit.
