P2703ABRP Equivalent & Substitute Parts

Part Overview

The P2703ABRP is a 230V off-state, 250A peak pulse TVS thyristor manufactured by Littelfuse in the SIDACtor® series. This component is designed for transient voltage suppression applications requiring three-element configuration in a 3-SIP through-hole package. The part is currently obsolete, making equivalent substitutes necessary for ongoing system support and new designs requiring compatible functionality.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the P2703ABRP is determined by electrical and mechanical parameter equivalence. The critical parameters defining substitutability are:

• Voltage ratings (breakover, off-state, and on-state)
• Peak pulse current capabilities (both 8/20µs and 10/1000µs waveforms)
• Hold current specification
• Number of elements (3-element configuration)
• Capacitance values
• Physical package type (3-SIP) and mounting method (through-hole)

The substitute parts P2703ABL and P2703ABLRP maintain identical electrical specifications and package configuration. The primary differences are product status (active versus obsolete) and packaging format (bulk versus tape & reel).

Parameter Comparison

Engineering Selection Recommendations

Both P2703ABL and P2703ABLRP are direct functional equivalents to the obsolete P2703ABRP, with identical electrical performance and mechanical compatibility. Selection between these two active alternatives depends on procurement and assembly requirements:

P2703ABL is supplied in bulk packaging format, suitable for applications with lower volume requirements or manual assembly processes.

P2703ABLRP is supplied in tape & reel format, optimized for automated assembly and higher-volume production environments.

Both substitute parts carry ROHS3 compliance certification, addressing regulatory requirements that the original P2703ABRP does not meet. The REACH unaffected status of both substitutes confirms their suitability for European market applications.

Frequently Asked Questions (FAQ)

Q: Can P2703ABL and P2703ABLRP be used interchangeably with P2703ABRP?

A: Yes. Both parts maintain identical electrical specifications (voltage ratings, current ratings, hold current) and physical package configuration (3-SIP, TO-220 Modified, through-hole mounting). The differences are product status and packaging format only.

Q: What is the difference between P2703ABL and P2703ABLRP?

A: Both parts are electrically and mechanically identical. P2703ABL is packaged in bulk format, while P2703ABLRP is packaged in tape & reel format. Selection depends on assembly method and volume requirements.

Q: Why is the original P2703ABRP marked as obsolete?

A: The P2703ABRP is no longer in active production. The active equivalents P2703ABL and P2703ABLRP provide the same functionality with current manufacturing support and regulatory compliance.

Q: Are there any compliance differences between the original and substitute parts?

A: Yes. The P2703ABRP is RoHS non-compliant, while both P2703ABL and P2703ABLRP are ROHS3 compliant. Both substitutes are REACH unaffected. For applications requiring regulatory compliance, the substitute parts are the appropriate selection.

Q: Will the substitute parts fit the same PCB footprint and through-hole pattern?

A: Yes. All three parts use the 3-SIP package with TO-220 Modified supplier device package and through-hole mounting type, ensuring identical PCB compatibility.

Q: What inventory status should I expect for these parts?

A: P2703ABL has 1850 pieces in stock (bulk packaging). P2703ABLRP has 1086 pieces in stock (tape & reel packaging). Availability may vary by supplier and region.
