Substitute Part Grouping Explanation

Substitution of the CPC3703C is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Criteria:

• FET Type: N-Channel
• Technology: MOSFET (Metal Oxide)
• Drain to Source Voltage (Vdss): 250V
• Continuous Drain Current (Id): 360mA @ 25°C
• On-State Resistance (Rds On): 4 Ohm @ 200mA, 0V
• Gate-Source Voltage (Vgs): ±15V maximum
• Input Capacitance (Ciss): 350pF @ 25V
• FET Feature: Depletion Mode
• Operating Temperature Range: -55°C to 125°C

Mechanical Equivalence Criteria:

• Mounting Type: Surface Mount
• Package / Case: TO-243AA (SOT-89-3)

The CPC3703CTR meets all electrical and mechanical equivalence criteria and qualifies as a direct substitute for the CPC3703C.

Parameter Comparison

Engineering Selection Recommendations

CPC3703CTR as Primary Substitute:

The CPC3703CTR is the direct equivalent substitute for the CPC3703C. All electrical parameters, mechanical specifications, and operating characteristics are identical. The CPC3703CTR carries Active product status, ensuring continued availability and supply chain support, whereas the CPC3703C is classified as Obsolete.

Compliance and Certification:

The CPC3703CTR is RoHS3 Compliant and maintains REACH Unaffected status, consistent with the CPC3703C. Both parts carry ECCN classification EAR99 and HTSUS code 8541.29.0095. Moisture Sensitivity Level (MSL) is 1 (Unlimited) for both variants.

Packaging Considerations:

The CPC3703CTR is available in Cut Tape (CT) and Digi-Reel® packaging options, providing flexibility for both manual and automated assembly processes. The CPC3703C standard packaging remains compatible with existing board designs and assembly equipment configured for SOT-89-3 surface-mount packages.

Inventory and Availability:

Current inventory of CPC3703CTR (1485 pieces) exceeds that of CPC3703C (1106 pieces), supporting sustained production requirements and reducing supply risk.

Frequently Asked Questions (FAQ)

Q: Can CPC3703CTR be used as a direct replacement for CPC3703C in existing designs?

A: Yes. The CPC3703CTR is electrically and mechanically equivalent to the CPC3703C. All critical parameters—voltage rating, current rating, on-state resistance, gate voltage, input capacitance, and operating temperature range—are identical. The SOT-89-3 package footprint is the same, enabling direct board-level substitution without design modification.

Q: What is the difference between CPC3703C and CPC3703CTR?

A: The primary differences are product status and packaging format. The CPC3703C is classified as Obsolete, while CPC3703CTR is Active. The CPC3703CTR is supplied in Cut Tape (CT) and Digi-Reel® packaging, whereas CPC3703C uses standard packaging. Electrical and mechanical specifications are identical.

Q: Are there any compliance or certification differences between these parts?

A: No. Both CPC3703C and CPC3703CTR maintain identical compliance status: RoHS3 Compliant (CPC3703CTR), REACH Unaffected, ECCN EAR99, and HTSUS 8541.29.0095. Moisture Sensitivity Level is 1 (Unlimited) for both.

Q: What is the significance of Depletion Mode in this MOSFET?

A: Depletion Mode indicates that this N-Channel MOSFET conducts current in its default state (with zero gate-source voltage) and requires a negative gate voltage to turn off. This is distinct from Enhancement Mode MOSFETs, which require positive gate voltage to conduct. Design circuits must account for this operational characteristic.

Q: Is the SOT-89-3 package compatible with standard surface-mount assembly equipment?

A: Yes. The SOT-89-3 package (TO-243AA case) is a standard surface-mount package compatible with conventional pick-and-place and reflow soldering processes. Both CPC3703C and CPC3703CTR use this package format.

Q: What inventory considerations should guide part selection?

A: CPC3703CTR has higher current inventory (1485 pieces) compared to CPC3703C (1106 pieces). For new production or long-term supply planning, CPC3703CTR is recommended due to Active product status and greater availability.
