Key Parameters

Substitute Part Grouping Explanation

Substitution of the P1304UATP is determined by strict equivalence across the following critical parameters:

• Voltage ratings: Breakover voltage (160V, 320V) and off-state voltage (120V, 240V) must match exactly
• Current specifications: Peak pulse current (8/20µs) of 150A and hold current (Ih) of 150mA must be identical
• On-state voltage: 4V maximum
• Element count: 4 elements required
• Capacitance range: 25pF to 45pF
• Package configuration: 6-SMD, Gull Wing surface mount form factor
• Supplier device package: Modified MS-013

The P1304UALTP meets all these criteria and is classified as a direct manufacturer equivalent with identical electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

The P1304UALTP is the direct functional equivalent of the P1304UATP with identical electrical and mechanical specifications. The primary distinction is product status and regulatory compliance. The P1304UATP is obsolete, while the P1304UALTP maintains active production status. Additionally, the P1304UALTP is ROHS3 compliant and REACH unaffected, whereas the P1304UATP is RoHS non-compliant. For new designs and ongoing system support, the P1304UALTP is the appropriate selection. The packaging difference (tube versus unspecified for the original) does not affect electrical performance or PCB integration.

Frequently Asked Questions (FAQ)

Q: Can the P1304UALTP directly replace the P1304UATP in existing designs?

A: Yes. The P1304UALTP is electrically and mechanically identical to the P1304UATP across all critical parameters including voltage ratings, current specifications, element count, and package configuration. Direct substitution is supported.

Q: What is the significance of the product status difference?

A: The P1304UATP is classified as obsolete, indicating discontinued production. The P1304UALTP is active production, ensuring long-term availability and supply chain continuity.

Q: Does the RoHS compliance difference affect compatibility?

A: RoHS compliance is a regulatory and environmental requirement, not an electrical performance parameter. The P1304UALTP's ROHS3 compliance makes it suitable for applications with regulatory requirements. Both parts are functionally equivalent.

Q: Are there packaging considerations for substitution?

A: Both parts use identical 6-SMD, Gull Wing surface mount packages with Modified MS-013 supplier device packaging. The P1304UALTP is supplied in tube packaging, which is standard for production components and does not affect electrical or mechanical compatibility.

Q: What parameters must remain constant for substitution?

A: Voltage ratings (160V/320V breakover, 120V/240V off-state), peak pulse current (150A at 8/20µs), hold current (150mA), on-state voltage (4V), element count (4), and package type (6-SMD, Gull Wing) must all match exactly.
