Current - Collector (Ic) (Max): 1.5 A minimum
Power - Max: 900 mW minimum
Operating Temperature: 150°C (TJ) minimum
Mounting Type: Surface Mount
RoHS Status: ROHS3 Compliant

Secondary Compatibility Factors:

Package / Case: SC-96 or equivalent surface mount packages (TO-236-3, SC-59, SOT-23-3)

Engineering Selection Recommendations

Parametric Equivalent:

CPH3115-TL-E is a parametric equivalent to CPH3115-TL-H, offering identical electrical specifications and the same SC-96 package. Both parts are obsolete; however, CPH3115-TL-E maintains higher inventory availability (2450 pcs vs. 15420 pcs for the main part). This part is suitable for direct substitution in applications requiring exact electrical performance matching.

Active Alternatives with Enhanced Performance:

CPH3144-TL-E is an active onsemi product offering superior collector current capability (2A vs. 1.5A) while maintaining the same 30V breakdown voltage and 900mW power rating. This part is suitable for applications where increased current headroom is beneficial. The SC-96 package ensures mechanical compatibility.

2SB1695TL and 2SB1695KT146 are active Rohm Semiconductor products meeting the 30V/1.5A electrical requirements. Both parts feature higher DC current gain (270 vs. 200) and lower saturation voltage (370mV vs. 375mV), providing improved switching characteristics. Package options include SC-96 (2SB1695TL) and SOT-23-3 (2SB1695KT146), with the latter offering smaller footprint. Transition frequency is reduced to 280MHz, suitable for applications not requiring 450MHz performance.

2STR2230 is an active STMicroelectronics product meeting all critical electrical parameters with extended operating temperature range (-65°C to 150°C). This part features the lowest transition frequency (100MHz) and highest saturation voltage (800mV), making it suitable for lower-frequency applications. SOT-23-3 package provides compact form factor.

All substitute parts maintain ROHS3 compliance, MSL 1 rating, and REACH unaffected status, ensuring regulatory and environmental compatibility with the original CPH3115-TL-H.

Frequently Asked Questions (FAQ)

Q: Can CPH3115-TL-E be used as a direct replacement for CPH3115-TL-H?

A: Yes. CPH3115-TL-E is a parametric equivalent with identical electrical specifications (30V, 1.5A, 450MHz, 900mW) and the same SC-96 package. Both parts are obsolete; however, CPH3115-TL-E is available in higher quantities.

Q: What is the primary difference between CPH3144-TL-E and CPH3115-TL-H?

A: CPH3144-TL-E provides higher maximum collector current (2A vs. 1.5A) while maintaining the same voltage rating (30V) and power dissipation (900mW). CPH3144-TL-E is an active product, whereas CPH3115-TL-H is obsolete. This part is suitable for applications requiring increased current capacity.

Q: Are the Rohm Semiconductor parts (2SB1695TL and 2SB1695KT146) compatible with the CPH3115-TL-H?

A: Both Rohm parts meet the critical electrical parameters (30V, 1.5A) and are active products. Key differences include reduced transition frequency (280MHz vs. 450MHz), improved DC current gain (270 vs. 200), and lower saturation voltage (370mV vs. 375mV). 2SB1695TL uses SC-96 package; 2SB1695KT146 uses SOT-23-3 package. Selection depends on frequency requirements and available PCB footprint.

Q: What are the package considerations when substituting with 2SB1695KT146 or 2STR2230?

A: The original CPH3115-TL-H uses SC-96 package. 2SB1695KT146 and 2STR2230 use SOT-23-3 package (also designated TO-236-3 or SC-59). These packages are mechanically different; PCB layout modifications are required. Verify pin configuration and footprint compatibility before implementation.

Q: Is 2STR2230 suitable for high-frequency applications?

A: 2STR2230 has a transition frequency of 100MHz, significantly lower than CPH3115-TL-H (450MHz). This part is suitable for applications operating below 100MHz. For applications requiring 450MHz performance, CPH3115-TL-E or CPH3144-TL-E are more appropriate selections.

Q: Do all substitute parts comply with environmental and regulatory requirements?

A: Yes. All listed substitute parts are ROHS3 compliant, have MSL 1 (Unlimited) rating, and are REACH unaffected, matching the compliance profile of CPH3115-TL-H.

Q: What is the inventory status of available substitutes?

A: CPH3144-TL-E (35300 pcs), 2SB1695TL (99300 pcs), 2SB1695KT146 (267100 pcs), and 2STR2230 (209400 pcs) are all active products with substantial inventory. CPH3115-TL-E (2450 pcs) and CPH3115-TL-H (15420 pcs) are obsolete with limited remaining stock.
