P2703UBRP Equivalent & Substitute Parts

Part Overview

The P2703UBRP is a 230V off-state TVS thyristor from Littelfuse Inc.'s SIDACtor® series, designed for transient voltage suppression applications. This component features a 6-SMD gull wing package with a peak pulse current rating of 250 A (8/20µs) and is currently classified as obsolete. Due to its discontinued status, identifying functionally equivalent active alternatives is essential for ongoing design support and procurement continuity.

Key Parameters

Substitute Part Grouping Explanation

The P2703UBLRP qualifies as a direct substitute for the P2703UBRP based on identical electrical and mechanical specifications. Substitution eligibility is determined by the following critical parameters:

• Voltage ratings (breakover, off-state, and on-state) must match exactly
• Peak pulse current ratings (both 8/20µs and 10/1000µs) must be identical
• Hold current (Ih) must be equivalent
• Number of elements must be the same
• Package type and mounting configuration must be compatible
• Capacitance values must align

The P2703UBLRP maintains all these parameters while differing only in packaging format (tape & reel versus bulk) and product status (active versus obsolete).

Parameter Comparison

Engineering Selection Recommendations

The P2703UBLRP is the direct functional equivalent for the obsolete P2703UBRP. Selection between these parts should be based on the following criteria:

For new designs or production requiring regulatory compliance, the P2703UBLRP is the appropriate choice due to its active product status and ROHS3 compliance certification. This part maintains full electrical and mechanical compatibility while offering improved compliance posture.

For legacy system support or repair applications where the original P2703UBRP specification must be maintained, the P2703UBLRP provides identical performance characteristics and can be substituted without circuit redesign or re-qualification.

The primary distinction between these parts is packaging format: the P2703UBLRP is supplied in tape & reel configuration, which is standard for production environments, whereas the P2703UBRP was supplied in bulk packaging. Both use the Modified MS-013 supplier device package and are compatible with identical PCB footprints.

Frequently Asked Questions (FAQ)

Q: Can the P2703UBLRP be used as a direct replacement for the P2703UBRP?

A: Yes. All electrical parameters, mechanical dimensions, and package specifications are identical. The parts are functionally interchangeable at the circuit level.

Q: What is the difference between these two part numbers?

A: The primary difference is product status and packaging format. The P2703UBRP is obsolete and supplied in bulk; the P2703UBLRP is active and supplied in tape & reel. The P2703UBLRP also carries ROHS3 compliance certification, whereas the P2703UBRP does not.

Q: Are there any PCB layout or assembly considerations when switching to the P2703UBLRP?

A: No. Both parts use the 6-SMD gull wing package with Modified MS-013 supplier device package specifications. PCB footprints, solder pad layouts, and assembly processes remain unchanged.

Q: Does the tape & reel packaging of the P2703UBLRP affect performance?

A: No. Packaging format does not affect electrical performance or reliability. Tape & reel is the standard production format and offers no functional difference from bulk packaging.

Q: Is the P2703UBLRP suitable for applications requiring RoHS compliance?

A: Yes. The P2703UBLRP carries ROHS3 compliance certification and is suitable for applications with RoHS requirements.
