Key Parameters

Substitute Part Grouping Explanation

Substitution of the PH1430DLSX is based on the following critical parameters that must align between the original and substitute component:

Electrical Compatibility Criteria:

• Drain to Source Voltage (Vdss): 30V minimum rating required
• FET Type: N-Channel topology
• Technology: MOSFET (Metal Oxide) construction

Mechanical & Environmental Compatibility Criteria:

• Packaging Family: LFPAK series (surface mount)
• RoHS Compliance: ROHS3 Compliant
• Moisture Sensitivity Level: MSL 1 (Unlimited)
• REACH Status: REACH Unaffected

The substitute part PSMN1R4-30YLDX meets all these criteria while offering enhanced performance characteristics and active product status, ensuring long-term availability and supply chain stability.

Parameter Comparison

Engineering Selection Recommendations

The PSMN1R4-30YLDX is the qualified substitute for the obsolete PH1430DLSX based on the following engineering factors:

Compliance & Regulatory Alignment: Both components maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory requirements are met in applications subject to environmental directives.

Product Lifecycle Status: The PH1430DLSX is obsolete, creating supply constraints. The PSMN1R4-30YLDX maintains active product status with 29,300 units in stock, providing reliable long-term availability.

Electrical Equivalence: Both components are N-Channel MOSFETs with identical 30V Vdss ratings, establishing direct functional compatibility at the core voltage level.

Packaging Compatibility: Both components utilize LFPAK surface mount packaging with MSL 1 rating, enabling direct board-level substitution without redesign of solder profiles or thermal management approaches.

Enhanced Performance: The PSMN1R4-30YLDX provides specified performance metrics (100A continuous drain current, 1.42mOhm Rds On, 166W power dissipation) that exceed typical requirements for applications previously served by the PH1430DLSX.

Frequently Asked Questions (FAQ)

Q: Can the PSMN1R4-30YLDX be used as a direct replacement for the PH1430DLSX?

A: Yes. Both components share identical Vdss (30V), FET type (N-Channel), technology (MOSFET), and packaging family (LFPAK surface mount). Regulatory compliance (ROHS3, REACH) and moisture sensitivity levels (MSL 1) are equivalent, supporting direct substitution.

Q: What is the primary reason for substituting the PH1430DLSX?

A: The PH1430DLSX is classified as obsolete. The PSMN1R4-30YLDX is an active product with substantial inventory availability, ensuring supply chain continuity and eliminating sourcing risk.

Q: Are there packaging differences between these components?

A: Both components use LFPAK surface mount packaging. The PSMN1R4-30YLDX is specified as LFPAK56 (SC-100, SOT-669), representing an enhanced variant within the LFPAK family. This maintains mechanical and thermal compatibility.

Q: Do these components have the same environmental ratings?

A: Yes. Both components are MSL 1 (Unlimited moisture sensitivity), ROHS3 compliant, and REACH unaffected, meeting identical environmental and regulatory requirements.

Q: What performance improvements does the PSMN1R4-30YLDX offer?

A: The PSMN1R4-30YLDX provides specified electrical characteristics including 100A continuous drain current, 1.42mOhm on-resistance, and 166W power dissipation capability. These parameters ensure robust performance in applications requiring higher current handling or thermal management.

Q: Is board-level redesign required for substitution?

A: No. Both components are surface mount devices within the LFPAK family. Footprint compatibility and thermal characteristics are maintained, allowing direct substitution without PCB layout modifications.
