P3403ABRP Equivalent & Substitute Parts

Part Overview

The P3403ABRP is a 300V off-state, 250A peak pulse TVS thyristor manufactured by Littelfuse Inc. in the SIDACtor® series. This component is packaged in a 3-SIP TO-220 modified configuration and is designed for transient voltage suppression applications requiring high current handling capability.

The P3403ABRP is classified as obsolete. Equivalent substitute parts are available in active product status with identical electrical and mechanical specifications, differing only in packaging configuration and compliance certifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the P3403ABRP is determined by electrical parameter equivalence and mechanical compatibility. The following parameters must remain identical for direct substitution:

• Voltage - Breakover: 400V
• Voltage - Off State: 300V
• Voltage - On State: 8V
• Current - Peak Pulse (8/20µs): 250A
• Current - Peak Pulse (10/1000µs): 80A
• Current - Hold (Ih): 150mA
• Number of Elements: 3
• Capacitance: 45pF, 65pF
• Package / Case: 3-SIP
• Mounting Type: Through Hole
• Supplier Device Package: TO-220 Modified

The substitute parts P3403ABL and P3403ABLRP meet all electrical and mechanical requirements. Differences exist only in packaging format (bulk versus tape & reel) and product status (active versus obsolete).

Parameter Comparison

Engineering Selection Recommendations

Both P3403ABL and P3403ABLRP are direct electrical and mechanical equivalents to the P3403ABRP. Selection between these substitutes depends on procurement and assembly requirements:

P3403ABL is supplied in bulk packaging and is suitable for applications where individual component handling and manual assembly are acceptable. This part carries ROHS3 compliance certification.

P3403ABLRP is supplied in tape & reel format and is suitable for automated assembly processes. This part also carries ROHS3 compliance certification and REACH unaffected status.

Both substitute parts are in active product status, ensuring long-term availability and supply chain continuity compared to the obsolete P3403ABRP.

Frequently Asked Questions (FAQ)

Q: Can P3403ABL and P3403ABLRP be used interchangeably with P3403ABRP?

A: Yes. All three parts share identical electrical parameters (voltage ratings, current ratings, capacitance) and mechanical specifications (3-SIP package, TO-220 modified configuration, through-hole mounting). Substitution is valid from an electrical and mechanical standpoint.

Q: What is the difference between P3403ABL and P3403ABLRP?

A: The primary difference is packaging format. P3403ABL is supplied in bulk packaging, while P3403ABLRP is supplied in tape & reel format. Both parts are electrically and mechanically identical. Tape & reel packaging is optimized for automated assembly, while bulk packaging is suitable for manual assembly or lower-volume applications.

Q: Why is P3403ABRP listed as obsolete?

A: The P3403ABRP is obsolete, but equivalent active alternatives are available. P3403ABL and P3403ABLRP provide identical functionality and are recommended for new designs and replenishment orders.

Q: Are there any compliance differences between these parts?

A: P3403ABL and P3403ABLRP are ROHS3 compliant, while P3403ABRP is RoHS non-compliant. Both substitute parts carry REACH unaffected status. All three parts share the same ECCN (EAR99) and HTSUS (8541.30.0080) classifications.

Q: Can these parts be used in automated assembly?

A: P3403ABLRP in tape & reel format is designed for automated assembly processes. P3403ABL in bulk packaging can be used in automated assembly with appropriate handling equipment, though tape & reel format is the standard choice for high-volume automated production.
