Key Parameters

Substitute Part Grouping Explanation

Substitution for the CD214B-T7.5CALF is determined by the following critical electrical and mechanical parameters:

Primary Substitution Criteria:

• Voltage - Reverse Standoff (Typ): 7.5V
• Voltage - Clamping (Max) @ Ipp: 12.9V
• Current - Peak Pulse (10/1000µs): 46.5A (±0.1A tolerance acceptable)
• Power - Peak Pulse: 600W
• Package / Case: DO-214AA, SMB (surface mount compatibility)
• Bidirectional Channels: 1
• Type: Zener

Direct Equivalents maintain all electrical specifications within the stated tolerances and identical package format. These parts are functionally interchangeable without circuit modification.

Similar Substitutes maintain the core voltage and current ratings but may have minor variations in operating temperature range, peak pulse current (±2A variance), or clamping voltage (±0.7V variance). These parts are suitable for applications where the specified parameter variance does not impact circuit performance.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalents (Preferred for Replacement):

SMBJ7.5CA (MDD) and SMBJ7V5CA (Taiwan Semiconductor Corporation) are direct functional equivalents to the CD214B-T7.5CALF. Both parts maintain identical electrical specifications (7.5V standoff, 12.9V clamping, 46.5A peak pulse current) and package format. Both manufacturers' parts are currently in active production status with ROHS3 compliance and MSL 1 rating. SMBJ7.5CA offers the highest inventory availability (45,809 pcs) among active substitutes.

Compatible Substitutes (Application-Dependent):

SMBJ7.5CA-TP (Micro Commercial Co) provides an extended operating temperature range (-55°C ~ 175°C) compared to the main part (-55°C ~ 150°C), making it suitable for applications requiring higher temperature performance. This part maintains all core electrical specifications and is available in Tape & Reel packaging.

TV06B7V5JB-HF (Comchip Technology) maintains identical voltage and current specifications with 46.51A peak pulse current. Operating temperature range is not specified in available documentation.

Limited Compatibility:

SMBJ8.0CA (MDD) features a higher reverse standoff voltage (8V vs. 7.5V) and clamping voltage (13.6V vs. 12.9V) with slightly reduced peak pulse current (44.2A vs. 46.5A). This part is suitable only for applications where the higher voltage rating does not create circuit incompatibility and where the reduced current capacity is acceptable.

All substitute parts maintain ROHS3 compliance, MSL 1 rating, and 600W peak pulse power dissipation capability, ensuring regulatory and handling consistency with the original specification.

Frequently Asked Questions (FAQ)

Q: Can SMBJ7.5CA directly replace CD214B-T7.5CALF without circuit modification?

A: Yes. SMBJ7.5CA (MDD) maintains identical electrical specifications: 7.5V reverse standoff voltage, 12.9V clamping voltage, 46.6A peak pulse current, and 600W power dissipation. The SMB/DO-214AA package is mechanically and electrically compatible with the original part. No circuit modification is required.

Q: What is the difference between SMBJ7.5CA and SMBJ7V5CA?

A: Both parts are direct equivalents with identical electrical specifications (7.5V standoff, 12.9V clamping, 46.5A peak pulse current). The primary differences are manufacturer (MDD vs. Taiwan Semiconductor Corporation) and operating temperature range (SMBJ7.5CA: -50°C ~ 150°C; SMBJ7V5CA: -55°C ~ 150°C). SMBJ7V5CA offers a lower minimum operating temperature.

Q: Why is SMBJ8.0CA listed as a substitute if it has different voltage ratings?

A: SMBJ8.0CA is classified as a similar substitute due to its higher voltage rating (8V standoff, 13.6V clamping). It is suitable only for applications where the circuit can tolerate higher clamping voltage and where the reduced peak pulse current (44.2A vs. 46.5A) does not impact protection requirements. Direct equivalents (SMBJ7.5CA or SMBJ7V5CA) are preferred for standard replacement.

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

A: All substitute parts use the DO-214AA (SMB) surface mount package, ensuring mechanical compatibility with the original PCB layout. Packaging options vary by manufacturer: SMBJ7.5CA is available in standard packaging, SMBJ7.5CA-TP is supplied in Tape & Reel format, and SMBJ7V5CA is available in Cut Tape and Digi-Reel formats. Verify packaging requirements with your procurement specification.

Q: What is the inventory status of substitute parts?

A: SMBJ7.5CA (MDD) has the highest availability with 45,809 pcs in stock. SMBJ7V5CA (Taiwan Semiconductor) has 16,102 pcs available. SMBJ7.5CA-TP (Micro Commercial Co) has 2,991 pcs, and TV06B7V5JB-HF (Comchip) has 947 pcs. The original CD214B-T7.5CALF (Bourns) has 931 pcs remaining as obsolete stock.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating, ensuring regulatory consistency and handling compatibility with the original specification.
