Engineering Selection Recommendations

Primary Substitute: 3SMAJ5928B-TP

The 3SMAJ5928B-TP is the direct functional equivalent for the SMA5C13-TP. Both components share identical nominal Zener voltage (13 V) and maximum power rating (3 W) in the same DO-214AC surface mount package. The substitute part offers the following advantages:

• Active Product Status: The 3SMAJ5928B-TP maintains active production status, ensuring reliable long-term availability and supply chain continuity.
• Improved Tolerance: Voltage tolerance of ±5% compared to ±6.54% provides tighter specification control.
• Lower Impedance: Maximum impedance of 7 Ohms versus 10 Ohms delivers improved voltage regulation characteristics.
• Compliance Alignment: Both parts maintain ROHS3 compliance and MSL Level 1 rating, ensuring compatibility with modern manufacturing and environmental standards.

Operating Temperature Consideration: The substitute part operates across -55°C to 150°C, compared to the original part's -65°C to 150°C range. Applications requiring operation below -55°C require design review.

Packaging Availability: The 3SMAJ5928B-TP is available in Tape & Reel (TR) packaging, supporting automated assembly processes.

Frequently Asked Questions (FAQ)

Q: Can the 3SMAJ5928B-TP directly replace the SMA5C13-TP in existing designs?

A: Yes. Both components share identical nominal Zener voltage (13 V), maximum power dissipation (3 W), and DO-214AC surface mount package. The substitute part meets all primary electrical and mechanical compatibility requirements.

Q: What are the key differences between these two parts?

A: The primary differences are voltage tolerance (±5% versus ±6.54%), impedance (7 Ohms versus 10 Ohms), reverse leakage current specifications, forward voltage characteristics, and operating temperature range (-55°C to 150°C versus -65°C to 150°C). The substitute part offers tighter voltage tolerance and lower impedance.

Q: Does the lower operating temperature minimum of the substitute part affect compatibility?

A: Applications operating above -55°C experience no impact. Designs requiring operation at temperatures below -55°C must evaluate whether the reduced lower temperature limit affects system performance.

Q: Are both parts RoHS compliant?

A: Yes. Both the SMA5C13-TP and 3SMAJ5928B-TP are ROHS3 compliant with MSL Level 1 (Unlimited) moisture sensitivity rating.

Q: What is the significance of the product status difference?

A: The SMA5C13-TP is classified as obsolete, indicating discontinued production. The 3SMAJ5928B-TP maintains active product status, ensuring ongoing manufacturing support and supply availability for current and future production requirements.

Q: Are there packaging differences between these parts?

A: Both parts use the DO-214AC (SMA) surface mount package. The substitute part is available in Tape & Reel (TR) packaging format, which is standard for automated assembly operations.

Q: How do the impedance specifications compare?

A: The SMA5C13-TP has a maximum impedance of 10 Ohms, while the 3SMAJ5928B-TP has a maximum impedance of 7 Ohms. Lower impedance in the substitute part provides improved voltage regulation performance.
