P4802AC Equivalent & Substitute Parts

Part Overview

The P4802AC is a Transient Voltage Suppressor (TVS) thyristor manufactured by Littelfuse Inc. under the SIDACtor® series. This component is designed for 220V/440V off-state voltage applications with a peak pulse current rating of 400A in an 8/20µs waveform. The P4802AC is classified as obsolete, making identification of suitable substitute parts essential for ongoing system maintenance and new design implementations where this component specification is required.

Substitute Part Grouping Explanation

Substitution of the P4802AC is determined by strict equivalence across all electrical and mechanical parameters. The primary substitute part P4802ACL maintains identical electrical specifications including breakover voltage (300V, 600V), off-state voltage (220V, 440V), on-state voltage (4V), peak pulse current ratings (400A at 8/20µs and 100A at 10/1000µs), hold current (150mA), element count (2), capacitance range (50pF, 85pF), and mechanical form factor (3-SIP, TO-220 Modified through-hole package).

The key parameters determining substitution eligibility are:

• Voltage ratings (breakover and off-state)
• Peak pulse current capabilities
• Hold current specification
• Physical package configuration
• Element count and capacitance characteristics

Parameter Comparison

Engineering Selection Recommendations

The P4802ACL is the direct equivalent substitute for the P4802AC. Both components share identical electrical and mechanical specifications across all rated parameters. The primary distinction is product status and regulatory compliance: the P4802AC is obsolete, while the P4802ACL maintains active product status with ROHS3 compliance certification.

For applications requiring the P4802AC specification, the P4802ACL provides functional equivalence with the added benefit of current manufacturing support and enhanced regulatory compliance. The P4802ACL is available in bulk packaging with significantly higher inventory levels (2400 pcs vs. 946 pcs), supporting both immediate requirements and long-term supply continuity.

Frequently Asked Questions (FAQ)

Q: Can the P4802ACL directly replace the P4802AC in existing designs? A: Yes. The P4802ACL is electrically and mechanically identical to the P4802AC across all specified parameters, including voltage ratings, current capabilities, and package configuration. Direct substitution is supported without circuit modification.

Q: What is the difference between P4802AC and P4802ACL? A: The components are electrically equivalent. The primary differences are product status (P4802AC is obsolete; P4802ACL is active) and regulatory compliance (P4802ACL is ROHS3 compliant; P4802AC is RoHS non-compliant). Packaging differs (P4802AC standard vs. P4802ACL bulk).

Q: Are there any compatibility concerns with the 3-SIP TO-220 Modified package? A: No. Both parts use identical 3-SIP TO-220 Modified through-hole packages, ensuring mechanical and electrical compatibility with existing PCB layouts and mounting hardware.

Q: Does the P4802ACL meet current regulatory requirements? A: Yes. The P4802ACL is ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards for electronic component manufacturing and distribution.

Q: What inventory considerations should guide part selection? A: The P4802ACL offers substantially higher inventory availability (2400 pcs) compared to the P4802AC (946 pcs), supporting both immediate procurement needs and long-term supply chain planning.
