P4802ABTP Equivalent & Substitute Parts

Part Overview

The P4802ABTP is a Transient Voltage Suppressor (TVS) thyristor manufactured by Littelfuse Inc. as part of the SIDACtor® series. This component is designed for overvoltage protection applications, featuring dual-element configuration with 220V/440V off-state voltage ratings and 250A peak pulse current capability in a 3-SIP TO-220 Modified package. The P4802ABTP is classified as obsolete, making identification of active equivalent parts essential for new designs and ongoing system support.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the P4802ABTP is determined by electrical and mechanical parameter equivalence. The following criteria establish direct substitutability:

• Voltage ratings: Breakover voltage (300V, 600V) and off-state voltage (220V, 440V) must match exactly
• Current specifications: Peak pulse current (8/20µs and 10/1000µs) and hold current must be identical
• Element configuration: Dual-element (2) design must be maintained
• Capacitance range: 50pF to 85pF specification must be preserved
• Package compatibility: 3-SIP TO-220 Modified through-hole mounting required

The P4802ABL meets all these criteria and qualifies as a direct equivalent substitute.

Parameter Comparison

Engineering Selection Recommendations

The P4802ABL is the direct substitute for the obsolete P4802ABTP. Both components share identical electrical and mechanical specifications across all critical parameters. The primary distinction is product status and compliance posture:

• P4802ABTP: Obsolete status, RoHS non-compliant
• P4802ABL: Active product status, ROHS3 compliant, REACH unaffected

For new designs and systems requiring ongoing component availability, the P4802ABL is the appropriate selection. The active product status ensures continued supply chain access and manufacturing support. The ROHS3 compliance of the P4802ABL aligns with current regulatory requirements for electronic components in regulated markets.

Frequently Asked Questions (FAQ)

Q: Can P4802ABL be used as a direct replacement for P4802ABTP in existing designs?

A: Yes. The P4802ABL is electrically and mechanically identical to the P4802ABTP across all specified parameters, including voltage ratings, current ratings, element configuration, and package type. Direct substitution is supported without circuit modification.

Q: What is the difference between P4802ABTP and P4802ABL?

A: The components are functionally equivalent. The primary differences are product status (P4802ABTP is obsolete; P4802ABL is active) and regulatory compliance (P4802ABL is ROHS3 compliant). Packaging differs only in supplier designation (P4802ABTP is tape; P4802ABL is 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. PCB footprints, lead spacing, and mounting requirements are identical. No layout or assembly modifications are required.

Q: Why is the P4802ABTP listed as obsolete?

A: Obsolescence reflects Littelfuse Inc. product lifecycle management. The P4802ABL remains in active production with identical specifications, ensuring continued availability for applications requiring this performance class.

Q: What certifications apply to the P4802ABL?

A: The P4802ABL is ROHS3 compliant and REACH unaffected. Both components carry EAR99 export classification and HTSUS code 8541.30.0080.
