Parameter Comparison

Engineering Selection Recommendations

SMDA05C-5/TR13 (Microchip Technology) — Primary Part

The SMDA05C-5/TR13 is the specified component with active product status and 724 units in stock. This part is RoHS non-compliant and carries REACH Unaffected status. Selection of this part is appropriate for applications without RoHS compliance requirements.

ITA6V5B1RL (STMicroelectronics) — Substitute with Enhanced Specifications

The ITA6V5B1RL provides equivalent reverse standoff voltage (5V) and identical package configuration (8-SOIC). This substitute offers higher peak pulse current capability (25A versus 5A) and achieves ROHS3 compliance. The clamping voltage is 12V (1V higher than the primary part), and capacitance is 750pF at 1MHz. This part is suitable for applications requiring RoHS3 compliance or higher transient current handling within the same voltage protection class. Inventory availability is 8717 units.

SMDA05C-5.TBT (Semtech Corporation) — Substitute with Lower Clamping Voltage

The SMDA05C-5.TBT maintains identical reverse standoff voltage (5V) and 8-SOIC package compatibility. This substitute provides lower clamping voltage (9.8V versus 11V) and intermediate peak pulse current (17A). The part achieves RoHS compliance and operates across -55°C to 125°C temperature range. Capacitance is 350pF at 1MHz. This part is suitable for applications requiring RoHS compliance with tighter clamping voltage control. Inventory availability is 1892 units.

Compliance Considerations:

• Applications requiring RoHS compliance should select ITA6V5B1RL or SMDA05C-5.TBT
• All substitute parts maintain REACH Unaffected status
• All parts carry EAR99 ECCN classification and identical HTSUS code (8541.10.0080)

Frequently Asked Questions (FAQ)

Q: Can the ITA6V5B1RL replace the SMDA05C-5/TR13 in existing designs?

A: Yes. Both parts share identical reverse standoff voltage (5V), breakdown voltage minimum (6V or higher), and 8-SOIC package configuration. The ITA6V5B1RL provides higher peak pulse current (25A versus 5A) and slightly higher clamping voltage (12V versus 11V). These differences are within acceptable substitution parameters for general-purpose transient protection applications.

Q: What is the primary difference between the SMDA05C-5.TBT and the SMDA05C-5/TR13?

A: Both parts share the same reverse standoff voltage (5V) and package type (8-SOIC). The SMDA05C-5.TBT provides lower clamping voltage (9.8V versus 11V) and higher peak pulse current (17A versus 5A). The SMDA05C-5.TBT achieves RoHS compliance, while the SMDA05C-5/TR13 is RoHS non-compliant. Operating temperature range differs: SMDA05C-5.TBT operates to 125°C, while SMDA05C-5/TR13 operates to 150°C.

Q: Are all substitute parts mechanically compatible with the SMDA05C-5/TR13 footprint?

A: Yes. All three parts utilize 8-SOIC (0.154", 3.90mm width) surface mount packaging. Mechanical footprint and PCB land pattern compatibility is identical across all parts.

Q: Which substitute part should be selected for RoHS-compliant applications?

A: Both ITA6V5B1RL (ROHS3 compliant) and SMDA05C-5.TBT (RoHS compliant) meet RoHS requirements. The ITA6V5B1RL provides higher peak pulse current (25A) and 12V clamping voltage. The SMDA05C-5.TBT provides lower clamping voltage (9.8V) and 17A peak pulse current. Selection depends on specific transient current and voltage clamping requirements.

Q: What is the impact of capacitance differences between substitute parts?

A: Capacitance values range from 200pF (SMDA05C-5/TR13) to 750pF (ITA6V5B1RL) at 1MHz. Higher capacitance may affect high-frequency circuit performance. For general-purpose transient protection applications, these differences are typically acceptable. Circuit-specific validation is required for applications with stringent frequency response requirements.

Q: Can the SMDA05C-5.TBT be used in applications requiring -55°C to 150°C operation?

A: No. The SMDA05C-5.TBT operates across -55°C to 125°C, limiting operation above 125°C. The SMDA05C-5/TR13 operates to 150°C. For applications requiring full -55°C to 150°C operation, the SMDA05C-5/TR13 or ITA6V5B1RL (operating temperature range not specified in available data) should be selected.

Q: What packaging formats are available for these substitute parts?

A: The SMDA05C-5/TR13 is supplied in Tape & Reel (TR) packaging. The ITA6V5B1RL is available in Cut Tape (CT) and Digi-Reel® packaging. The SMDA05C-5.TBT is supplied in Tape & Reel (TR) packaging. All parts maintain identical 8-SOIC component configuration.
