ATP104-TL-H Equivalent & Substitute Parts

Part Overview

The ATP104-TL-H is a P-Channel MOSFET manufactured by onsemi, rated for 30V drain-to-source voltage and 75A continuous drain current in a surface mount ATPAK package. This device is classified as obsolete, necessitating identification of equivalent substitute components for ongoing design support and procurement. The ATP104-TL-H remains available in inventory (4200 pieces), but obsolete status requires engineers to evaluate active alternative devices that maintain functional compatibility within system requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ATP104-TL-H is determined by the following critical parameters:

Mandatory Compatibility Criteria:

• FET Type: P-Channel topology
• Technology: MOSFET (Metal Oxide)
• Mounting Type: Surface Mount
• Package / Case: ATPAK (2 Leads+Tab)
• Vgs (Max): ±20V gate voltage rating

Performance Envelope Criteria:

• Drain to Source Voltage (Vdss): Must equal or exceed 30V
• Current - Continuous Drain (Id) @ 25°C: Must equal or exceed 75A
• Power Dissipation (Max): Must equal or exceed 60W (Tc)
• Operating Temperature (TJ): Must equal or exceed 150°C

Regulatory & Compliance Criteria:

• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)
• REACH Status: REACH Unaffected

The ATP304-TL-H qualifies as a substitute because it maintains identical FET topology, technology, mounting type, and package configuration while exceeding all performance envelope requirements. The ATP304-TL-H provides higher voltage rating (60V vs. 30V), increased current capacity (100A vs. 75A), and greater power dissipation capability (90W vs. 60W), making it suitable for applications where the ATP104-TL-H is no longer procurable.

Engineering Selection Recommendations

ATP304-TL-H as Primary Substitute:

The ATP304-TL-H is the qualified substitute for the obsolete ATP104-TL-H based on the following engineering factors:

1. Product Status Alignment: The ATP304-TL-H maintains active product status with onsemi, ensuring long-term availability and manufacturing support. The ATP104-TL-H obsolete classification necessitates transition to an active equivalent.

2. Regulatory Compliance: Both devices maintain identical RoHS3 compliance, REACH unaffected status, and MSL 1 (Unlimited) moisture sensitivity rating, ensuring no additional supply chain or environmental qualification requirements.

3. Functional Compatibility: Both devices employ identical P-Channel MOSFET technology in ATPAK surface mount packaging with matching gate voltage specifications (±20V Vgs Max). This ensures direct compatibility with existing PCB layouts and gate drive circuitry.

4. Performance Envelope: The ATP304-TL-H exceeds all critical performance parameters of the ATP104-TL-H:

   • Vdss: 60V (vs. 30V) provides enhanced voltage margin
   • Id: 100A (vs. 75A) provides increased current capacity
   • Power Dissipation: 90W (vs. 60W) provides thermal headroom

5. Design Margin: The higher ratings of the ATP304-TL-H provide design margin for applications originally specified with ATP104-TL-H parameters. No circuit redesign is required for direct substitution in applications operating within ATP104-TL-H specifications.

Frequently Asked Questions (FAQ)

Q: Can the ATP304-TL-H directly replace the ATP104-TL-H in existing designs?

A: Yes. The ATP304-TL-H maintains identical FET topology (P-Channel MOSFET), package configuration (ATPAK), and gate voltage specifications (±20V). Both devices are surface mount components with matching pinout and tab configuration. No PCB modifications are required.

Q: What are the key differences between ATP104-TL-H and ATP304-TL-H?

A: The ATP304-TL-H provides higher performance specifications: 60V Vdss (vs. 30V), 100A continuous drain current (vs. 75A), and 90W power dissipation (vs. 60W). The ATP304-TL-H also features lower on-resistance (6.5 mOhm vs. 8.4 mOhm) but higher gate charge (250 nC vs. 76 nC) and input capacitance (13000 pF vs. 3950 pF).

Q: Does the ATP304-TL-H require different gate drive circuitry?

A: No. Both devices specify identical maximum gate voltage (±20V) and minimum/maximum drive voltages (4.5V, 10V). Existing gate drive circuits designed for ATP104-TL-H operate within ATP304-TL-H specifications.

Q: Are there thermal management considerations when substituting to ATP304-TL-H?

A: The ATP304-TL-H has higher power dissipation capability (90W vs. 60W) and lower on-resistance, which may reduce thermal load in current-limited applications. Thermal design margins improve with substitution. No additional cooling is required.

Q: What is the impact of higher gate charge in ATP304-TL-H?

A: The ATP304-TL-H gate charge is 250 nC (vs. 76 nC in ATP104-TL-H). This increases gate drive power requirements and switching transition time. Gate drive circuits must supply sufficient current to charge the gate within required switching frequency constraints. Existing gate drive designs must be verified for adequate current sourcing capability.

Q: What is the impact of higher input capacitance in ATP304-TL-H?

A: The ATP304-TL-H input capacitance is 13000 pF @ 20V (vs. 3950 pF @ 10V in ATP104-TL-H). Higher input capacitance increases gate drive current requirements and may extend switching transition times. Gate drive circuit performance must be evaluated for compatibility with increased capacitive loading.

Q: Are both devices RoHS compliant?

A: Yes. Both ATP104-TL-H and ATP304-TL-H are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating and REACH unaffected status. No additional environmental or supply chain qualification is required.

Q: Why is ATP104-TL-H obsolete?

A: Product obsolescence is determined by manufacturer lifecycle decisions. The ATP304-TL-H represents the active equivalent in onsemi's P-Channel MOSFET portfolio, providing superior performance specifications and long-term manufacturing support.

Q: Can ATP104-TL-H be used as a substitute for ATP304-TL-H?

A: No. The ATP104-TL-H has lower performance ratings (30V Vdss, 75A Id, 60W dissipation) and obsolete status. It does not qualify as a substitute for ATP304-TL-H applications requiring higher voltage or current specifications.
