Substitute Part Grouping Explanation

Substitution of the 50C02SS-TL-E is determined by electrical and mechanical compatibility across the following critical parameters:

Electrical Compatibility Criteria:

• Transistor Type: NPN configuration required
• Voltage - Collector Emitter Breakdown (Max): 50V minimum rating
• DC Current Gain (hFE): 300 minimum @ 10mA, 2V
• Vce Saturation: 100mV maximum @ 10mA, 100mA
• Current - Collector Cutoff (Max): 100nA maximum
• Frequency - Transition: 500MHz minimum
• Operating Temperature: 150°C maximum junction temperature

Mechanical Compatibility Criteria:

• Mounting Type: Surface Mount required
• Base Product Number: 50C02 series designation

Regulatory Compliance:

• RoHS3 Compliant status
• MSL Level 1 (Unlimited)

The 50C02CH-TL-E qualifies as a substitute because it maintains identical electrical specifications for voltage, current gain, saturation characteristics, and transition frequency while offering enhanced current handling (500mA vs. 400mA) and power dissipation (700mW vs. 200mW). Both devices share the same base product number (50C02) and comply with identical regulatory standards.

Parameter Comparison

Engineering Selection Recommendations

The 50C02CH-TL-E is the qualified substitute for the obsolete 50C02SS-TL-E based on the following engineering criteria:

Product Status Alignment: The 50C02CH-TL-E maintains Active product status, ensuring long-term availability and manufacturing support. The 50C02SS-TL-E is classified as Obsolete, making the 50C02CH-TL-E the appropriate alternative for new designs and ongoing production requirements.

Electrical Specification Equivalence: Both devices maintain identical core electrical parameters: 50V breakdown voltage, 300 minimum DC current gain, 100mV saturation voltage, and 500MHz transition frequency. The 50C02CH-TL-E provides enhanced ratings in collector current (500mA vs. 400mA) and power dissipation (700mW vs. 200mW), which represent design margin improvements without introducing incompatibility.

Regulatory Compliance: Both parts are ROHS3 Compliant and carry MSL Level 1 (Unlimited) moisture sensitivity ratings, ensuring equivalent environmental and regulatory qualification status.

Package Consideration: The 50C02CH-TL-E is available in TO-236-3, SC-59, and SOT-23-3 package options, which differ from the 50C02SS-TL-E SC-81 package. PCB layout modifications are required for package transition. The SC-59 package option provides the closest physical compatibility with the original SC-81 footprint for minimal redesign impact.

Frequently Asked Questions (FAQ)

Q: Can the 50C02CH-TL-E directly replace the 50C02SS-TL-E without circuit modification?

A: Electrical substitution is valid without circuit modification. The 50C02CH-TL-E maintains all critical electrical specifications (voltage, current gain, saturation characteristics, and frequency response). However, package geometry differs between SC-81 (50C02SS-TL-E) and the available options for 50C02CH-TL-E (TO-236-3, SC-59, SOT-23-3), requiring PCB footprint redesign.

Q: What is the primary reason for substituting the 50C02SS-TL-E?

A: The 50C02SS-TL-E is classified as Obsolete. The 50C02CH-TL-E is the equivalent Active product from onsemi's 50C02 base product line, ensuring continued availability and manufacturing support.

Q: Are there electrical performance differences between these devices?

A: Core electrical specifications are identical. The 50C02CH-TL-E provides higher maximum ratings for collector current (500mA vs. 400mA) and power dissipation (700mW vs. 200mW), which represent design margin enhancements and do not create incompatibility in applications designed for the 50C02SS-TL-E.

Q: Which package option for the 50C02CH-TL-E is most suitable for redesign?

A: The SC-59 package provides the closest physical compatibility with the original SC-81 footprint, minimizing PCB layout modifications during the transition from 50C02SS-TL-E to 50C02CH-TL-E.

Q: Do both devices meet the same regulatory and compliance standards?

A: Yes. Both the 50C02SS-TL-E and 50C02CH-TL-E are ROHS3 Compliant, REACH Unaffected, and carry MSL Level 1 (Unlimited) ratings, ensuring equivalent compliance status.

Q: What is the base product number significance?

A: Both devices share the base product number 50C02, indicating they are part of the same onsemi product family with equivalent electrical characteristics and design intent. This designation confirms substitution eligibility within the product line.
