TPD4E004DRYRG4 Equivalent & Substitute Parts

Part Overview

The TPD4E004DRYRG4 is a steering transient voltage suppressor (TVS) diode manufactured by Texas Instruments, designed for rail-to-rail protection in Ethernet applications. This 4-channel unidirectional TVS diode operates with a 5.5V reverse standoff voltage and 6V minimum breakdown voltage in a 6-SON surface mount package.

The TPD4E004DRYRG4 is currently discontinued at DiGi Electronics, necessitating identification of functionally equivalent alternatives for ongoing design support and component procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TPD4E004DRYRG4 is determined by the following critical parameters:

• Unidirectional Channels: Must equal 4 channels
• Type: Must be Steering (Rail to Rail)
• Voltage - Reverse Standoff (Typ): Must be 5.5V (Max)
• Voltage - Breakdown (Min): Must be 6V or higher
• Power Line Protection: Must support Yes
• Operating Temperature Range: Must cover -40°C ~ 85°C (TA)
• Mounting Type: Must be Surface Mount
• RoHS Status: Must be ROHS3 Compliant

Substitute parts are grouped based on exact alignment with these parameters. Parts meeting all criteria are considered direct functional equivalents.

Parameter Comparison

Engineering Selection Recommendations

TPD4E004DRYR is the primary recommended substitute. This Texas Instruments part maintains identical electrical specifications (5.5V reverse standoff, 6V breakdown voltage, 4-channel steering configuration) and package format (6-SON 1.45x1) as the discontinued TPD4E004DRYRG4. The TPD4E004DRYR is currently in active production status with 115,800 units in stock, ensuring long-term availability. Both parts share ROHS3 compliance, MSL 1 rating, and REACH unaffected status.

CM1213A-04S7 is an alternative substitute manufactured by onsemi. This part meets the 4-channel steering configuration and maintains the 6V minimum breakdown voltage. However, the CM1213A-04S7 differs in reverse standoff voltage (3.3V versus 5.5V) and uses a different package format (SC-70-6 versus 6-SON 1.45x1). The CM1213A-04S7 is in Last Time Buy status, indicating limited future availability. Selection of this part requires verification that the lower reverse standoff voltage and different package footprint are compatible with the target application.

Frequently Asked Questions (FAQ)

Q: Can TPD4E004DRYR be used as a direct replacement for TPD4E004DRYRG4?

A: Yes. The TPD4E004DRYR is a direct functional equivalent. Both parts share identical electrical specifications (5.5V reverse standoff, 6V breakdown voltage, 4-channel steering configuration), the same package format (6-SON 1.45x1), and equivalent compliance certifications (ROHS3, MSL 1, REACH unaffected). The primary difference is product status: TPD4E004DRYRG4 is discontinued, while TPD4E004DRYR is active production.

Q: Is CM1213A-04S7 compatible with designs using TPD4E004DRYRG4?

A: CM1213A-04S7 shares the 4-channel steering configuration and 6V breakdown voltage but differs in reverse standoff voltage (3.3V versus 5.5V) and package format (SC-70-6 versus 6-SON 1.45x1). Compatibility depends on whether the application can tolerate the lower reverse standoff voltage and whether the PCB layout can accommodate the different package footprint. This part is in Last Time Buy status.

Q: What are the critical parameters for substitution?

A: Substitution eligibility is determined by: 4-channel unidirectional configuration, steering (rail to rail) type, 5.5V reverse standoff voltage, 6V minimum breakdown voltage, power line protection capability, surface mount mounting type, and -40°C to 85°C operating temperature range.

Q: Does package format affect substitution?

A: Yes. The TPD4E004DRYRG4 uses a 6-SON (1.45x1) package. The TPD4E004DRYR uses the identical package format and is a direct PCB replacement. The CM1213A-04S7 uses SC-70-6 package format, requiring PCB layout modifications and footprint changes.

Q: What is the inventory status of available substitutes?

A: TPD4E004DRYR has 115,800 units in stock and is in active production status, ensuring long-term availability. CM1213A-04S7 has 17,800 units in stock but is in Last Time Buy status, indicating limited future procurement windows.
