P4802AA Equivalent & Substitute Parts

Part Overview

The P4802AA is a Transient Voltage Suppressor (TVS) thyristor manufactured by Littelfuse Inc., part of the SIDACtor® series. This component is designed for 220V/440V off-state voltage applications with a peak pulse current rating of 150A in an 8/20µs waveform. The P4802AA is classified as obsolete, making identification of suitable substitute parts essential for ongoing system maintenance and new design implementations where equivalent functionality is required.

Substitute Part Grouping Explanation

Substitute parts for the P4802AA are qualified based on electrical and mechanical parameter equivalence. The following criteria determine substitutability:

Electrical Parameters (Must Match):

• Voltage - Breakover: 300V, 600V
• Voltage - Off State: 220V, 440V
• Voltage - On State: 4 V
• Current - Peak Pulse (8/20µs): 150 A
• Current - Peak Pulse (10/1000µs): 45 A
• Current - Hold (Ih): 150 mA
• Number of Elements: 2
• Capacitance: 20pF, 35pF

Mechanical Parameters (Must Match):

• Mounting Type: Through Hole
• Package / Case: 3-SIP
• Supplier Device Package: TO-220 Modified

Both substitute parts (P4802AAL and P4802AALRP) maintain identical electrical and mechanical specifications to the P4802AA, differing only in packaging format and product status.

Parameter Comparison

Engineering Selection Recommendations

Both P4802AAL and P4802AALRP are direct functional equivalents to the P4802AA with identical electrical and mechanical specifications. Selection between these substitutes is determined by product availability, compliance requirements, and packaging needs.

P4802AAL is supplied in bulk packaging format and maintains active product status with ROHS3 compliance certification. This option is suitable for applications where standard packaging is acceptable and compliance with current environmental regulations is required.

P4802AALRP is supplied in Tape & Reel (TR) format and also maintains active product status with ROHS3 compliance certification. This packaging option is optimized for automated assembly processes and high-volume production environments.

Both substitute parts carry REACH Unaffected status and identical export classification (EAR99), making them suitable for regulated supply chain applications. The P4802AA's RoHS non-compliant status contrasts with the ROHS3 compliance of both substitutes, which may be a determining factor in applications subject to environmental compliance mandates.

Frequently Asked Questions (FAQ)

Q: Can P4802AAL and P4802AALRP be used interchangeably with P4802AA?

A: Yes. Both parts maintain identical electrical parameters (voltage ratings, current ratings, capacitance) and mechanical specifications (3-SIP package, TO-220 Modified form factor, through-hole mounting). The differences are limited to packaging format (bulk versus tape & reel) and product status (active versus obsolete).

Q: What is the primary difference between P4802AAL and P4802AALRP?

A: The primary difference is packaging format. P4802AAL is supplied in bulk packaging, while P4802AALRP is supplied in Tape & Reel (TR) format. Both parts are electrically and mechanically identical. Tape & Reel packaging is typically preferred for automated assembly operations, while bulk packaging may be suitable for manual assembly or lower-volume applications.

Q: Does the obsolete status of P4802AA affect substitution compatibility?

A: No. Obsolete status indicates that the manufacturer has discontinued production of the P4802AA. This makes substitution with active parts (P4802AAL or P4802AALRP) necessary for ongoing procurement. The electrical and mechanical equivalence remains unchanged.

Q: Are there compliance differences between the three parts?

A: Yes. The P4802AA is RoHS non-compliant, while both P4802AAL and P4802AALRP are ROHS3 compliant. Both substitutes carry REACH Unaffected status. Applications subject to environmental compliance requirements should use P4802AAL or P4802AALRP.

Q: Can these parts be used in new designs?

A: P4802AAL and P4802AALRP are suitable for new designs. The P4802AA should not be specified for new designs due to its obsolete status. Both active substitutes maintain the same electrical and mechanical characteristics required for 220V/440V transient voltage suppression applications.

Q: What packaging considerations apply to these parts?

A: All three parts use identical 3-SIP package and TO-220 Modified form factor, ensuring mechanical compatibility in PCB layouts and assembly fixtures. Packaging format selection (bulk versus tape & reel) depends on assembly process requirements and procurement volume.
