Key Parameters

Substitute Part Grouping Explanation

Substitution of the SMA5C6V2-TP is determined by the following critical electrical and mechanical parameters:

Electrical Matching Criteria:

• Zener voltage nominal rating: 6.2 V
• Maximum power dissipation: 3 W
• Package type: DO-214AC (SMA) surface mount

Compliance & Status Criteria:

• RoHS3 compliance requirement
• Active production status for supply continuity
• Moisture sensitivity level MSL 1 (Unlimited)

The substitute part 3SMAJ5920B-TP meets all core substitution requirements. Both parts share identical nominal zener voltage (6.2 V), maximum power rating (3 W), and identical package configuration (DO-214AC, SMA). Both maintain RoHS3 compliance and MSL 1 rating. The substitute part carries active product status, ensuring ongoing availability.

Parameter Comparison

Engineering Selection Recommendations

The 3SMAJ5920B-TP serves as a direct functional substitute for the obsolete SMA5C6V2-TP. Both components share identical core electrical specifications: 6.2 V nominal zener voltage and 3 W maximum power dissipation. Both utilize the same DO-214AC (SMA) surface mount package, enabling direct PCB layout compatibility without redesign.

The substitute part offers improved specifications in several areas: tighter voltage tolerance (±5% versus ±6.45%), lower impedance (2 Ohms versus 4 Ohms), and RoHS3 compliance matching the original. The 3SMAJ5920B-TP maintains active production status, ensuring supply chain continuity and long-term availability.

The substitute part exhibits a narrower operating temperature range (-55°C to 150°C versus -65°C to 150°C). Applications requiring operation below -55°C require evaluation against specific design requirements. The substitute part shows higher reverse leakage current (5 µA @ 4 V versus 1 µA @ 3 V) and higher forward voltage (1.5 V @ 200 mA versus 1.2 V @ 200 mA); these differences fall within acceptable ranges for standard zener diode applications.

Frequently Asked Questions (FAQ)

Q: Can the 3SMAJ5920B-TP directly replace the SMA5C6V2-TP without PCB modifications?

A: Yes. Both components use identical DO-214AC (SMA) surface mount packages with matching pinout and footprint geometry. No PCB layout changes are required.

Q: What is the significance of the product status difference (Obsolete vs. Active)?

A: The SMA5C6V2-TP is obsolete, indicating discontinued production and limited remaining inventory. The 3SMAJ5920B-TP carries active status, confirming ongoing manufacture and reliable long-term supply availability for production and future orders.

Q: How do the tolerance specifications differ between these parts?

A: The SMA5C6V2-TP specifies ±6.45% tolerance, while the 3SMAJ5920B-TP specifies ±5% tolerance. The substitute part provides tighter voltage tolerance, resulting in more precise zener voltage regulation across the specified range.

Q: Are both parts RoHS3 compliant?

A: Yes. Both the SMA5C6V2-TP and 3SMAJ5920B-TP are RoHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity rating, meeting current environmental and reliability standards.

Q: What is the impact of the operating temperature range difference?

A: The SMA5C6V2-TP operates from -65°C to 150°C, while the 3SMAJ5920B-TP operates from -55°C to 150°C. Applications requiring operation below -55°C must evaluate whether the narrower range of the substitute part meets specific design requirements.

Q: How do the impedance specifications affect circuit performance?

A: The 3SMAJ5920B-TP exhibits lower impedance (2 Ohms versus 4 Ohms), resulting in improved voltage regulation and faster transient response. This represents an enhancement over the original part for most standard zener diode applications.

Q: What packaging format is the 3SMAJ5920B-TP supplied in?

A: The 3SMAJ5920B-TP is supplied in Tape & Reel (TR) format, suitable for automated assembly processes. The SMA5C6V2-TP packaging format was not specified in available data.
