Key Parameters

Substitute Part Grouping Explanation

Substitution of the PCP1203-P-TD-H is determined by the following critical electrical and mechanical parameters:

Primary Substitution Criteria:

• Transistor Type: NPN configuration
• Package / Case: TO-243AA surface mount package
• Voltage - Collector Emitter Breakdown (Max): Equal to or greater than 30V
• Current - Collector (Ic) (Max): Equal to or greater than 1.5A
• Mounting Type: Surface mount
• Operating Temperature: 150°C (TJ) or higher

Secondary Compatibility Factors:

• DC Current Gain (hFE): Minimum 200 @ 100mA, 2V or equivalent
• Frequency - Transition: 150MHz or higher
• RoHS3 Compliance and MSL Level 1 rating

Substitute parts are classified into two categories:

MFR Recommended Substitute: Parts explicitly designated by the manufacturer as direct replacements, maintaining the highest level of design compatibility.

Similar Substitute: Parts meeting all critical electrical and mechanical parameters within the allowed specification range, suitable for applications where the primary substitute is unavailable.

Engineering Selection Recommendations

2SD1623T-TD-E (MFR Recommended Substitute)

The 2SD1623T-TD-E is the manufacturer-recommended substitute for the PCP1203-P-TD-H. Both devices are manufactured by onsemi and share identical package specifications (TO-243AA) and operating temperature ratings (150°C TJ). The 2SD1623T-TD-E maintains active product status, ensuring long-term availability and supply chain continuity.

The 2SD1623T-TD-E exceeds the electrical requirements of the main part with higher voltage rating (50V vs. 30V) and increased collector current capability (2A vs. 1.5A). This device is suitable for direct replacement in applications where the original specification does not require the full 500MHz transition frequency of the PCP1203-P-TD-H.

Both parts carry ROHS3 compliance and MSL Level 1 rating, ensuring compatibility with modern manufacturing and environmental standards.

2SCR512PT100 (Similar Substitute)

The 2SCR512PT100, manufactured by Rohm Semiconductor, meets all critical electrical and mechanical substitution criteria. This device maintains the 30V collector-emitter breakdown voltage of the original part while providing increased collector current (2A vs. 1.5A) and superior power dissipation capability (2W vs. 1.3W).

The 2SCR512PT100 operates at 320MHz transition frequency, exceeding the minimum requirement while remaining below the original part's 500MHz specification. DC current gain matches the original specification at 200 (Min) @ 100mA, 2V.

This part is classified as active and carries ROHS3 compliance and MSL Level 1 rating. The TO-243AA package and surface mount configuration provide mechanical compatibility with existing PCB designs.

Frequently Asked Questions (FAQ)

Q: Can the 2SD1623T-TD-E be used as a direct replacement for the PCP1203-P-TD-H?

A: Yes. The 2SD1623T-TD-E is the manufacturer-recommended substitute. Both devices share identical package specifications (TO-243AA), mounting type (surface mount), and operating temperature ratings (150°C TJ). The 2SD1623T-TD-E provides higher voltage and current ratings, making it suitable for direct replacement in existing designs.

Q: What is the primary difference between the MFR Recommended substitute and the Similar substitute?

A: The 2SD1623T-TD-E is explicitly designated by onsemi as the recommended replacement and maintains the same manufacturer lineage. The 2SCR512PT100 is manufactured by Rohm Semiconductor and meets all critical electrical and mechanical parameters but represents a cross-manufacturer alternative. Both are active products with full compliance certifications.

Q: Are there any package or mounting differences between these parts?

A: No. All three parts—PCP1203-P-TD-H, 2SD1623T-TD-E, and 2SCR512PT100—use the TO-243AA package and surface mount configuration. PCB footprints and assembly processes remain unchanged.

Q: How do the power dissipation ratings compare?

A: The PCP1203-P-TD-H is rated for 1.3W maximum power dissipation. The 2SD1623T-TD-E is rated for 500mW, while the 2SCR512PT100 is rated for 2W. Applications requiring the full 1.3W dissipation capability should use the 2SCR512PT100. The 2SD1623T-TD-E is suitable for applications operating below 500mW.

Q: What is the significance of the transition frequency difference?

A: The PCP1203-P-TD-H operates at 500MHz transition frequency. The 2SD1623T-TD-E operates at 150MHz, and the 2SCR512PT100 operates at 320MHz. For applications requiring high-frequency switching above 320MHz, the 2SD1623T-TD-E may not be suitable. The 2SCR512PT100 provides adequate frequency response for most general-purpose switching applications.

Q: Are all three parts RoHS3 compliant?

A: Yes. The PCP1203-P-TD-H, 2SD1623T-TD-E, and 2SCR512PT100 are all ROHS3 compliant with MSL Level 1 (Unlimited) moisture sensitivity rating. All parts are suitable for use in applications subject to RoHS directives.

Q: What is the DC current gain difference, and does it affect substitution?

A: The PCP1203-P-TD-H and 2SCR512PT100 both specify a minimum DC current gain (hFE) of 200 @ 100mA, 2V. The 2SD1623T-TD-E specifies a minimum of 100 @ 100mA, 2V. For applications requiring higher current gain, the 2SCR512PT100 or original part is preferred. For general-purpose switching applications, the 2SD1623T-TD-E is acceptable.

Q: Why is the PCP1203-P-TD-H classified as obsolete?

A: The PCP1203-P-TD-H has reached end-of-life status with onsemi. The manufacturer recommends transitioning to the 2SD1623T-TD-E for new designs and ongoing production. Existing inventory of the original part remains available, but long-term supply cannot be guaranteed.
