Key Parameters

Substitute Part Grouping Explanation

Substitution of the CPH5517-TL-E is determined by compatibility across the following critical electrical and mechanical parameters:

Electrical Compatibility Criteria:

• Transistor configuration (NPN/PNP topology)
• Maximum collector current rating (Ic Max)
• Maximum collector-emitter breakdown voltage (VCEO Max)
• Maximum power dissipation (P Max)
• Transition frequency (fT)
• DC current gain (hFE)
• Operating temperature range

Mechanical Compatibility Criteria:

• Surface mount packaging format
• SOT-23-5 Thin (TSOT-23-5) package footprint
• 5-CPH supplier device package designation

The CPH5520-TL-E qualifies as a direct substitute based on matching package geometry, surface mount technology, and core electrical performance envelope. Both devices share identical transition frequency (420MHz), operating temperature maximum (150°C), and DC current gain specifications (200 @ 100mA, 2V). The CPH5520-TL-E provides enhanced electrical ratings, including higher maximum collector current (2A versus 1A) and increased power dissipation (1.2W versus 900mW), making it suitable for applications requiring the CPH5517-TL-E specifications.

Parameter Comparison

Engineering Selection Recommendations

The CPH5520-TL-E is the designated substitute for the obsolete CPH5517-TL-E. Selection of the CPH5520-TL-E is supported by the following factors:

Product Status: The CPH5517-TL-E carries Obsolete status, indicating discontinued manufacturing and limited availability. The CPH5520-TL-E maintains Active product status with confirmed inventory of 12,400 pieces, ensuring supply chain continuity.

Compliance Certifications: Both devices maintain ROHS3 compliance and REACH Unaffected status, satisfying regulatory requirements for electronic component procurement. Moisture Sensitivity Level (MSL) rating of 1 (Unlimited) is identical across both parts, eliminating handling and storage requirement changes.

Electrical Performance: The CPH5520-TL-E provides enhanced electrical specifications within the same package footprint. Maximum collector current increases from 1A to 2A, and maximum power dissipation increases from 900mW to 1.2W. These improvements accommodate applications at or near the CPH5517-TL-E operational limits without circuit redesign.

Package Compatibility: Both devices utilize identical SOT-23-5 Thin (TSOT-23-5) surface mount packaging, enabling direct PCB footprint compatibility without layout modifications.

Frequently Asked Questions (FAQ)

Q: Can the CPH5520-TL-E directly replace the CPH5517-TL-E in existing designs?

A: The CPH5520-TL-E is electrically and mechanically compatible with the CPH5517-TL-E. Both devices share identical SOT-23-5 Thin package geometry, transition frequency (420MHz), DC current gain (200 @ 100mA, 2V), and operating temperature maximum (150°C). The CPH5520-TL-E provides higher current and power ratings, making it suitable for applications designed around CPH5517-TL-E specifications.

Q: What is the primary difference between the CPH5517-TL-E and CPH5520-TL-E?

A: The CPH5517-TL-E features a Common Base transistor topology with 1A maximum collector current and 900mW power dissipation at 50V breakdown voltage. The CPH5520-TL-E features an Emitter Coupled topology with 2A maximum collector current and 1.2W power dissipation, supporting both 80V and 50V breakdown voltages. Both devices maintain identical transition frequency and DC current gain specifications.

Q: Are there packaging differences between these parts?

A: No. Both the CPH5517-TL-E and CPH5520-TL-E utilize the SOT-23-5 Thin (TSOT-23-5) surface mount package with identical pinout and footprint dimensions. The CPH5517-TL-E is supplied in Cut Tape (CT) & Digi-Reel packaging, while the CPH5520-TL-E is supplied in Tape & Reel (TR) format. Both packaging formats are compatible with standard surface mount assembly equipment.

Q: Does the CPH5520-TL-E maintain the same compliance certifications?

A: Yes. Both devices are ROHS3 compliant, REACH Unaffected, and carry identical Moisture Sensitivity Level (MSL) rating of 1 (Unlimited). No changes to handling, storage, or regulatory documentation are required when transitioning from CPH5517-TL-E to CPH5520-TL-E.

Q: Why is the CPH5517-TL-E listed as Obsolete?

A: The CPH5517-TL-E has been discontinued by the manufacturer. The CPH5520-TL-E represents the active product line continuation, offering enhanced electrical performance within the same package format. Existing inventory of CPH5517-TL-E is limited (1,680 pieces), while CPH5520-TL-E inventory is substantially higher (12,400 pieces), supporting long-term supply availability.

Q: Are there applications where the CPH5517-TL-E cannot be substituted with the CPH5520-TL-E?

A: The CPH5520-TL-E provides equal or superior electrical performance across all specified parameters. Applications designed for CPH5517-TL-E operation remain fully compatible with CPH5520-TL-E. The higher current and power ratings of the CPH5520-TL-E do not create incompatibility with designs operating below these limits.
