Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RB480YNPT2R are identified based on the following critical parameters that determine functional compatibility:

Primary Substitution Criteria:

• Technology: Schottky diode
• Voltage - DC Reverse (Vr) (Max): 30 V minimum
• Current - Average Rectified (Io): Equal to or greater than 100 mA per diode
• Voltage - Forward (Vf) (Max) @ If: Compatible forward voltage characteristics
• Current - Reverse Leakage @ Vr: Leakage characteristics at rated reverse voltage
• Mounting Type: Surface Mount
• RoHS Status: ROHS3 Compliant

Two substitute parts are identified:

1. RB520SM-30T2R – Single diode configuration with higher current rating (200 mA) and active product status. Different package (SC-79, SOD-523) and supplier device package (EMD2).

2. RB480YT2R – Parametric equivalent with identical electrical specifications and diode array configuration (2 independent). Same package (SC-75-4, SOT-543) and supplier device package (EMD4). Obsolete product status.

Parameter Comparison

Engineering Selection Recommendations

RB480YT2R is the parametric equivalent substitute. This part maintains identical electrical specifications, diode configuration (2 independent), forward voltage characteristics, and package form factor (SC-75-4, SOT-543). Both parts are obsolete; however, RB480YT2R offers higher inventory availability (26,494 units in stock versus 8,100 units for RB480YNPT2R). This substitute requires no circuit redesign and provides direct form-fit-function replacement.

RB520SM-30T2R is a functional alternative for applications where single diode configuration is acceptable. This part is active product status, ensuring long-term supply chain availability. The RB520SM-30T2R provides higher current rating (200 mA versus 100 mA), higher maximum junction temperature (150°C versus 125°C), and improved forward voltage characteristics at higher current levels (580 mV @ 200 mA). However, this substitute requires PCB layout modification due to different package (SC-79, SOD-523) and supplier device package (EMD2). Applications requiring dual independent diodes cannot use this substitute without circuit redesign.

Both substitutes maintain ROHS3 compliance, unlimited moisture sensitivity level (MSL 1), and equivalent reverse leakage characteristics.

Frequently Asked Questions (FAQ)

Q: Can RB480YT2R directly replace RB480YNPT2R without PCB modification?

A: Yes. RB480YT2R is a parametric equivalent with identical package (SC-75-4, SOT-543), supplier device package (EMD4), and electrical specifications. Direct PCB substitution is possible without layout changes.

Q: What is the key difference between RB520SM-30T2R and the main part?

A: RB520SM-30T2R is a single diode configuration rated for 200 mA, whereas RB480YNPT2R contains 2 independent diodes each rated for 100 mA. RB520SM-30T2R uses a different package (SC-79, SOD-523) and requires PCB redesign. This substitute is suitable only for applications requiring a single diode function.

Q: Why is RB520SM-30T2R recommended despite package differences?

A: RB520SM-30T2R is the only active product substitute available. It provides long-term supply chain continuity and higher performance specifications (200 mA current rating, 150°C maximum junction temperature). Applications can accommodate this substitute if circuit topology permits single diode operation and PCB layout can be modified.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. RB480YT2R and RB520SM-30T2R are both ROHS3 compliant, matching the compliance status of RB480YNPT2R.

Q: What is the inventory status of available substitutes?

A: RB480YT2R has 26,494 units in stock. RB520SM-30T2R has 493,100 units in stock. RB480YNPT2R has 8,100 units in stock.

Q: Can RB520SM-30T2R be used in parallel to replace dual diode functionality?

A: Parallel configuration of RB520SM-30T2R is not recommended as a substitute for the dual independent diode array. This approach introduces additional design complexity, PCB layout changes, and potential current distribution issues. RB480YT2R remains the appropriate substitute for dual diode applications.

Q: What are the moisture sensitivity considerations for these parts?

A: All three parts (RB480YNPT2R, RB480YT2R, and RB520SM-30T2R) have MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.
