CPH6532-TL-E Equivalent & Substitute Parts

Part Overview

The CPH6532-TL-E is a Bipolar (BJT) Transistor Array featuring a dual 2 NPN configuration manufactured by onsemi. This surface mount component is rated for 50V collector-emitter breakdown voltage and 1A maximum collector current, with a transition frequency of 420MHz and maximum power dissipation of 1.1W. The device is packaged in a 6-CPH (SOT-23-6 Thin) configuration.

The CPH6532-TL-E is classified as obsolete. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production requirements for applications utilizing this dual NPN transistor array.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CPH6532-TL-E is determined by the following critical electrical and mechanical parameters:

Electrical Compatibility Criteria:

• Transistor configuration: Dual 2 NPN array
• Maximum collector current: 1A or greater
• Collector-emitter breakdown voltage: Must equal or exceed 50V
• Package type: SOT-23-6 Thin (TSOT-23-6) surface mount
• Mounting compatibility: Surface mount technology

Operational Constraints:

• Maximum junction temperature rating: 150°C or higher
• Moisture sensitivity level: 1 (Unlimited) or equivalent
• Regulatory compliance: REACH Unaffected status

The QSX8TR from Rohm Semiconductor meets the dual 2 NPN transistor array requirement and surface mount package specification. However, the QSX8TR has a maximum collector-emitter breakdown voltage of 30V, which is below the 50V specification of the CPH6532-TL-E. This voltage limitation restricts the QSX8TR to applications where the supply voltage and operating conditions do not exceed 30V.

Parameter Comparison

Engineering Selection Recommendations

CPH6532-TL-E (onsemi): The CPH6532-TL-E is classified as obsolete. While inventory is currently available (790 pcs), this part number will not be replenished. The device carries REACH Unaffected status and EAR99 export classification. Selection of this part is appropriate only for existing stock utilization or legacy system maintenance where supply constraints are acceptable.

QSX8TR (Rohm Semiconductor): The QSX8TR is an active product with robust supply availability (3,066 pcs in stock). This part is RoHS3 compliant and carries REACH Unaffected status with EAR99 export classification. The QSX8TR is suitable for new designs and ongoing production where supply continuity is required.

Substitution Feasibility: The QSX8TR can substitute the CPH6532-TL-E in applications where the maximum operating voltage does not exceed 30V. Both devices share identical collector current ratings (1A), matching package configurations (SOT-23-6 Thin), and equivalent moisture sensitivity levels. The QSX8TR provides higher maximum power dissipation (1.25W vs. 1.1W) and superior DC current gain (270 vs. 200 @ 100mA, 2V), offering improved performance margins in low-voltage applications.

Applications requiring the full 50V breakdown voltage rating of the CPH6532-TL-E cannot use the QSX8TR as a direct substitute. In such cases, alternative dual NPN transistor arrays with 50V or higher ratings must be evaluated.

Frequently Asked Questions (FAQ)

Q: Can the QSX8TR directly replace the CPH6532-TL-E in all applications?

A: No. The QSX8TR has a maximum collector-emitter breakdown voltage of 30V, compared to the CPH6532-TL-E's 50V rating. Direct substitution is limited to applications where the supply voltage and peak operating voltages do not exceed 30V. Applications requiring 50V operation must use alternative components.

Q: Are the package configurations identical between these parts?

A: Yes. Both the CPH6532-TL-E and QSX8TR use the SOT-23-6 Thin (TSOT-23-6) surface mount package. PCB footprints and reflow soldering profiles are compatible.

Q: What are the differences in saturation voltage between these devices?

A: The CPH6532-TL-E has a maximum Vce saturation of 190mV at 10mA base current and 500mA collector current. The QSX8TR has a maximum Vce saturation of 350mV at 25mA base current and 500mA collector current. The CPH6532-TL-E exhibits lower saturation voltage under its specified test conditions.

Q: Does the QSX8TR offer any performance advantages?

A: The QSX8TR provides higher maximum power dissipation (1.25W vs. 1.1W), superior DC current gain (270 vs. 200 @ 100mA, 2V), and is an active product with guaranteed supply availability. These characteristics provide improved design margins for low-voltage applications.

Q: What is the significance of the obsolete status of the CPH6532-TL-E?

A: Obsolete status indicates that onsemi will not manufacture or replenish inventory of this part. Current stock (790 pcs) represents the final available supply. For new designs or long-term production, the active QSX8TR or alternative components must be selected.

Q: Are both parts compliant with environmental and export regulations?

A: Yes. Both the CPH6532-TL-E and QSX8TR carry REACH Unaffected status and EAR99 export classification. The QSX8TR additionally meets RoHS3 compliance requirements.

Q: What is the moisture sensitivity level for both devices?

A: Both devices have a Moisture Sensitivity Level (MSL) of 1 (Unlimited), indicating no moisture sensitivity restrictions for storage, handling, or reflow soldering processes.
