• On-State Resistance (Rds On): 130mOhm @ 13.2A, 10V
• Gate Threshold Voltage: 4V @ 1mA
• Gate Charge: 28nC @ 10V
• Maximum Power Dissipation: 81.1W
• Operating Temperature Range: -55°C to 175°C

Mechanical Equivalence Criteria:

• Package: TO-220-3
• Mounting: Through Hole
• Channel Type: P-Channel
• Technology: MOSFET (Metal Oxide)

The substitute part SPP18P06PHXKSA1 meets all electrical and mechanical parameters specified above. The primary distinction between the main part and substitute is packaging format (bulk versus tube) and product status (Obsolete versus Active).

Parameter Comparison

Engineering Selection Recommendations

The SPP18P06PHXKSA1 is a direct parametric equivalent to the SPP18P06PHKSA1 across all electrical and mechanical specifications. Selection of the substitute part is supported by the following factors:

Product Status: The SPP18P06PHKSA1 is classified as Obsolete, whereas SPP18P06PHXKSA1 maintains Active status. Active product status ensures continued manufacturer support, availability, and compliance with current regulatory requirements.

Regulatory Compliance: SPP18P06PHXKSA1 is certified as ROHS3 Compliant, providing assurance of compliance with current environmental and hazardous substance restrictions. Both parts maintain REACH Unaffected status and EAR99 export classification.

Packaging Consideration: The substitute part is supplied in Tube packaging format, which is standard for active production components. The original part's bulk packaging reflects its obsolete status. Tube packaging does not affect electrical performance or mechanical compatibility in TO-220-3 through-hole applications.

Inventory Availability: SPP18P06PHXKSA1 shows significantly higher inventory availability (1801 Pcs) compared to the obsolete part (882 Pcs), supporting long-term procurement reliability.

For applications currently using SPP18P06PHKSA1, direct substitution with SPP18P06PHXKSA1 is supported without circuit modification or re-qualification, provided the application operates within the specified electrical and thermal parameters.

Frequently Asked Questions (FAQ)

Q: Can SPP18P06PHXKSA1 be used as a direct replacement for SPP18P06PHKSA1 in existing designs?

A: Yes. SPP18P06PHXKSA1 is electrically and mechanically equivalent to SPP18P06PHKSA1. All electrical parameters, including voltage rating, current rating, on-state resistance, and thermal characteristics, are identical. Both devices use the same TO-220-3 through-hole package. No circuit modifications are required.

Q: What is the difference between the two part numbers?

A: The primary differences are product status and packaging format. SPP18P06PHKSA1 is Obsolete and supplied in bulk packaging. SPP18P06PHXKSA1 is Active and supplied in Tube packaging. The "X" designation in the part number indicates the tube packaging format. Electrical performance is identical.

Q: Why is the original part marked as Obsolete?

A: Obsolete status indicates that the manufacturer has discontinued active production and support for this specific part number variant. SPP18P06PHXKSA1 represents the current active production equivalent within the SIPMOS® P-Channel MOSFET product line.

Q: Are there any thermal or electrical performance differences between these parts?

A: No. Both parts are rated for identical maximum power dissipation (81.1W), operating temperature range (-55°C to 175°C), and all electrical parameters. Thermal performance in equivalent circuit applications will be identical.

Q: Does the tube packaging affect performance or reliability?

A: No. Tube packaging is a standard distribution format for through-hole components and does not affect electrical performance, reliability, or thermal characteristics. Tube packaging provides improved component protection during storage and handling compared to bulk formats.

Q: Are both parts RoHS compliant?

A: SPP18P06PHXKSA1 is certified as ROHS3 Compliant. The original part's RoHS status is not specified in available documentation. Both parts maintain REACH Unaffected status.

Q: What is the gate charge specification, and why is it important?

A: Gate charge (Qg) is specified as 28nC @ 10V for both parts. This parameter determines the switching speed and gate drive requirements. Identical gate charge ensures equivalent switching performance and driver circuit compatibility.

Q: Can these parts be used interchangeably in high-frequency switching applications?

A: Yes. Identical gate charge (28nC), input capacitance (860pF), and on-state resistance (130mOhm) specifications ensure equivalent switching characteristics and performance in high-frequency applications.
