Substitute Part Grouping Explanation

The P0904UBLRP qualifies as a direct substitute for the P0904UBRP based on identical electrical and mechanical parameters. Substitution is valid when the following criteria are met:

• Voltage ratings (breakover, off-state, and on-state) are identical
• Peak pulse current capabilities (8/20µs and 10/1000µs) match exactly
• Hold current (Ih) specification is the same
• Number of internal elements is identical
• Capacitance values are equivalent
• Package type (6-SMD, Gull Wing) and mounting configuration are identical
• Supplier device package designation remains unchanged

The P0904UBLRP maintains all electrical performance characteristics of the P0904UBRP while offering improved product lifecycle status and enhanced compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The P0904UBLRP is the appropriate selection for new designs and system replacements. This part carries Active product status, ensuring long-term availability and manufacturer support. The P0904UBLRP is ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for commercial and industrial applications. The P0904UBRP, classified as obsolete and RoHS non-compliant, should be phased out in favor of the P0904UBLRP to ensure compliance with modern procurement standards and supply chain continuity.

Both parts are supplied in Tape & Reel packaging format, suitable for automated assembly processes. Inventory availability is adequate for both components, with 1011 units of the P0904UBLRP currently in stock.

Frequently Asked Questions (FAQ)

Q: Can the P0904UBLRP be used as a direct replacement for the P0904UBRP in existing designs?

A: Yes. The P0904UBLRP is electrically and mechanically identical to the P0904UBRP. All voltage ratings, current specifications, capacitance values, and package dimensions match exactly, enabling direct substitution without circuit modification.

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

A: The P0904UBLRP offers improved product lifecycle status (Active vs. Obsolete) and enhanced compliance certifications (ROHS3 compliant and REACH unaffected). Electrical performance is identical.

Q: Are there packaging differences between P0904UBRP and P0904UBLRP?

A: Both parts use the same 6-SMD Gull Wing package with Modified MS-013 supplier device package designation. The P0904UBLRP is supplied in Tape & Reel format, standard for surface mount assembly.

Q: What are the key electrical parameters that define substitution eligibility?

A: Substitution is valid when breakover voltage (98V, 196V), off-state voltage (75V, 175V), on-state voltage (4V), peak pulse current (250 A at 8/20µs), hold current (150 mA), and element count (4) remain unchanged.

Q: Is the P0904UBLRP suitable for new product designs?

A: Yes. The P0904UBLRP is the recommended choice for new designs due to its Active product status and full compliance with current RoHS and REACH regulations.
