• Inverting and non-inverting input types
• Through-hole mounting

Substitute Parts Identified:

1. TC4425AVPA (Microchip Technology) – Active product status, same base part number, 8-DIP package variant
2. MAX628MJA/883B (Analog Devices Inc./Maxim Integrated) – Active product status, identical package format (8-CERDIP), military-grade qualification

Parameter Comparison

Engineering Selection Recommendations

TC4425AVPA Selection Criteria:

• Preferred for new designs requiring active product status and RoHS3 compliance
• Higher peak output current (4.5A vs. 3A) provides improved drive capability
• Faster switching performance (12ns rise/fall time vs. 23ns/25ns)
• Extended upper operating temperature limit to 150°C
• 8-DIP package requires PCB layout adjustment from original 8-CERDIP footprint
• Maintains Microchip Technology manufacturer continuity

MAX628MJA/883B Selection Criteria:

• Suitable for applications requiring military-grade qualification (MIL-STD-883)
• Identical 8-CERDIP package format enables direct PCB substitution
• Lower peak output current (2A vs. 3A) requires circuit evaluation for drive adequacy
• RoHS non-compliant status restricts use in regulated markets
• Operating temperature upper limit of 125°C (TA) is lower than TC4425MJA
• Analog Devices Inc./Maxim Integrated manufacturer source

Frequently Asked Questions (FAQ)

Q: Can TC4425AVPA directly replace TC4425MJA on the PCB? A: TC4425AVPA uses an 8-DIP package versus the original 8-CERDIP package. While pin count and spacing are identical, the package body dimensions differ. PCB footprint modification is required for proper component mounting.

Q: What are the key differences in output current capability? A: TC4425MJA and TC4425AVPA both support 3A and 4.5A peak output current respectively. MAX628MJA/883B provides 2A peak output current. Circuit designs dependent on higher drive current should use TC4425AVPA.

Q: Is MAX628MJA/883B suitable for RoHS-regulated applications? A: No. MAX628MJA/883B is RoHS non-compliant. Applications subject to RoHS requirements must use TC4425AVPA, which carries ROHS3 compliance.

Q: What is the temperature operating range difference? A: TC4425MJA operates to 150°C (junction temperature). TC4425AVPA extends to 150°C (junction temperature). MAX628MJA/883B operates to 125°C (ambient temperature). Temperature-critical applications should evaluate these limits against design requirements.

Q: Are the logic input thresholds identical across all three parts? A: Yes. All three parts maintain VIL of 0.8V and VIH of 2.4V, ensuring compatible signal interface requirements.

Q: Which substitute offers the fastest switching performance? A: TC4425AVPA provides the fastest rise and fall times at 12ns each, compared to 23ns/25ns for TC4425MJA and 25ns/20ns for MAX628MJA/883B.
