TP0610K-T1 P-Channel MOSFET Equivalent & Substitute Parts

Part Overview

The TP0610K-T1 is a P-Channel MOSFET manufactured by Vishay Siliconix, rated for 60V drain-to-source voltage with 185mA continuous drain current in a SOT-23-3 surface mount package. This device is part of the TrenchFET® series and is currently classified as obsolete. Due to its obsolete status and limited inventory (5010 pcs), identifying equivalent and substitute parts is necessary for ongoing design support, production continuity, and long-term component availability. Parametric equivalents and manufacturer-recommended alternatives are available from both Vishay Siliconix and Infineon Technologies.

Substitute Part Grouping Explanation

Substitution eligibility for the TP0610K-T1 is determined by strict adherence to the following electrical and mechanical parameters:

Primary Substitution Criteria:

Drain to Source Voltage (Vdss): 60V (exact match required)
FET Type: P-Channel (exact match required)
Package Type: SOT-23-3 / TO-236-3 / SC-59 (exact match required)
Operating Temperature Range: -55°C to 150°C (exact match required)
Technology: MOSFET (Metal Oxide) (exact match required)

Secondary Compatibility Parameters:

Continuous Drain Current (Id): 185mA or higher
On-State Resistance (Rds On): 6 Ohm or lower (at specified conditions)
Gate Threshold Voltage (Vgs(th)): 3V or lower
Power Dissipation: 350mW or higher
Gate Charge (Qg): 1.7nC or lower
Input Capacitance (Ciss): 23pF or lower

Substitute parts are grouped into two categories:

Category 1: Parametric Equivalents (Vishay Siliconix) TP0610K-T1-E3 and TP0610K-T1-GE3 are direct parametric equivalents with identical electrical specifications. These parts differ only in packaging format (Cut Tape vs. Tape & Reel) and product status (Active vs. Obsolete). Both maintain full compatibility with the original TP0610K-T1 design.

Category 2: Manufacturer-Recommended Alternatives (Infineon Technologies) BSS84PH6327XTSA2 and BSS84PH6433XTMA1 are Infineon SIPMOS® devices that meet the primary substitution criteria. These parts operate within acceptable parameter tolerances for the TP0610K-T1 application space, with minor variations in secondary parameters.

Engineering Selection Recommendations

For Direct Replacement (Preferred): TP0610K-T1-E3 and TP0610K-T1-GE3 are recommended as primary substitutes. Both parts are active products with identical electrical and thermal specifications to the original TP0610K-T1. Selection between these two depends on packaging requirements: TP0610K-T1-E3 is supplied in Cut Tape format with 485,400 pcs inventory, while TP0610K-T1-GE3 is supplied in Tape & Reel format with 439,600 pcs inventory. Both maintain ROHS3 compliance and MSL 1 rating.

For Cross-Manufacturer Substitution: BSS84PH6327XTSA2 (Infineon, Active status) is the preferred alternative when Vishay Siliconix parts are unavailable. This part meets all primary substitution criteria with acceptable parameter variations: continuous drain current is 170mA (versus 185mA), on-state resistance is 8 Ohm (versus 6 Ohm), and gate threshold voltage is 2V (versus 3V). Power dissipation is 360mW, exceeding the original 350mW specification. Inventory availability is 20,200 pcs.

For Extended Availability: BSS84PH6433XTMA1 (Infineon, Last Time Buy status) provides additional inventory (93,200 pcs) but carries Last Time Buy designation, indicating limited future availability. This part is electrically equivalent to BSS84PH6327XTSA2 and meets all primary substitution criteria. Use only when BSS84PH6327XTSA2 is unavailable and long-term supply is not required.

Compliance Verification: All substitute parts maintain ROHS3 compliance, REACH Unaffected status, and MSL 1 (Unlimited) moisture sensitivity rating, ensuring compatibility with existing supply chain and manufacturing processes.

Frequently Asked Questions (FAQ)

Q1: Can TP0610K-T1-E3 and TP0610K-T1-GE3 be used interchangeably with the original TP0610K-T1?

A: Yes. Both parts are parametric equivalents with identical electrical specifications, operating temperature range, and package type (SOT-23-3). The only difference is packaging format: TP0610K-T1-E3 is supplied in Cut Tape format, while TP0610K-T1-GE3 is supplied in Tape & Reel format. Selection depends on assembly equipment compatibility and procurement requirements.

Q2: What are the key differences between Vishay Siliconix and Infineon substitute options?

A: Vishay Siliconix equivalents (TP0610K-T1-E3, TP0610K-T1-GE3) provide identical electrical performance. Infineon alternatives (BSS84PH6327XTSA2, BSS84PH6433XTMA1) have slightly different specifications: 170mA continuous drain current (versus 185mA), 8 Ohm on-state resistance (versus 6 Ohm), and 2V gate threshold voltage (versus 3V). Both manufacturers' parts meet the 60V Vdss, SOT-23-3 package, and -55°C to 150°C operating range requirements.

Q3: Are the Infineon BSS84PH parts suitable for direct PCB replacement?

A: Yes. Both BSS84PH6327XTSA2 and BSS84PH6433XTMA1 use PG-SOT23 packaging, which is mechanically and electrically compatible with SOT-23-3 (TO-236) footprints. Pin configuration and functional operation are identical. However, verify that the slightly higher on-state resistance (8 Ohm versus 6 Ohm) and lower continuous drain current (170mA versus 185mA) do not exceed application thermal or current requirements.

Q4: Why is BSS84PH6433XTMA1 marked as "Last Time Buy"?

A: Last Time Buy status indicates that Infineon has announced end-of-life for this part number. While current inventory is available (93,200 pcs), future orders may not be possible. For new designs or long-term production, use BSS84PH6327XTSA2 (Active status) instead.

Q5: Do all substitute parts maintain the same compliance certifications?

A: Yes. All substitute parts (TP0610K-T1-E3, TP0610K-T1-GE3, BSS84PH6327XTSA2, BSS84PH6433XTMA1) are ROHS3 compliant, REACH Unaffected, and carry MSL 1 (Unlimited) moisture sensitivity rating. ECCN and HTSUS classifications are identical across all parts.

Q6: What is the recommended substitution priority order?

A: Priority order is as follows: (1) TP0610K-T1-E3 or TP0610K-T1-GE3 (direct parametric equivalents, active status, highest inventory); (2) BSS84PH6327XTSA2 (Infineon alternative, active status, acceptable parameter variations); (3) BSS84PH6433XTMA1 (Infineon alternative, Last Time Buy status, use only when others unavailable).
