Key Parameters

Substitute Part Grouping Explanation

Substitution of the MRF19030LSR3 is based on strict alignment of the following electrical and mechanical parameters:

Electrical Parameters for Substitution:

• Operating frequency: 1.96 GHz
• LDMOS technology classification
• Voltage rating compatibility: Test voltage and rated voltage within acceptable operating ranges
• Power output capability: Minimum 4W output power
• Gain characteristics: Minimum 13 dB

Mechanical Parameters for Substitution:

• Package type: Surface mount or chassis mount configurations
• Mounting compatibility with circuit board design requirements

The substitute part MW6S004NT1 maintains the same operating frequency (1.96 GHz) and LDMOS technology as the original MRF19030LSR3. While the substitute exhibits different voltage ratings (28V test, 68V rated), current ratings (50 mA test), power output (4W), and gain (18 dB), these parameters fall within the allowable substitution criteria for RF MOSFET LDMOS devices in this frequency band. The substitute transitions from chassis mount to surface mount packaging, requiring circuit board layout modifications.

Parameter Comparison

Engineering Selection Recommendations

The MW6S004NT1 is an active product from NXP USA Inc. and represents the manufacturer-recommended substitute for the obsolete MRF19030LSR3. Both components maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for new designs.

Selection of MW6S004NT1 requires evaluation of the following factors:

Product Status: The substitute is classified as active, ensuring long-term availability and manufacturing support compared to the obsolete original part.

Compliance Certifications: Both components are ROHS3 compliant and REACH unaffected, maintaining environmental and regulatory compliance standards.

Packaging Transition: The shift from NI-400S chassis mount to PLD-1.5 surface mount packaging necessitates circuit board redesign and PCB layout modifications. This transition impacts thermal management, mounting hardware, and interconnection strategies.

Moisture Sensitivity: The substitute exhibits MSL 3 (168 Hours) compared to MSL 1 (Unlimited) for the original part, requiring stricter moisture control during storage, handling, and assembly processes.

Frequently Asked Questions (FAQ)

Q: Can MW6S004NT1 directly replace MRF19030LSR3 without circuit modifications?

A: No. The MW6S004NT1 requires circuit board layout modifications due to the package change from NI-400S chassis mount to PLD-1.5 surface mount. Thermal management and interconnection strategies must be re-evaluated.

Q: What are the key electrical differences between these parts?

A: The MW6S004NT1 operates at slightly higher test voltage (28V vs. 26V) and rated voltage (68V vs. 65V). Output power differs significantly (4W vs. 30W), and gain is higher (18 dB vs. 13 dB). Current rating is lower (50 mA vs. 300 mA). Both operate at identical frequency (1.96 GHz) using LDMOS technology.

Q: Are there compliance or certification concerns with substitution?

A: Both components are ROHS3 compliant and REACH unaffected. The substitute exhibits higher moisture sensitivity (MSL 3 vs. MSL 1), requiring enhanced moisture control during manufacturing and assembly.

Q: Why is the original part obsolete?

A: The MRF19030LSR3 is classified as obsolete by the manufacturer. The MW6S004NT1 is the active equivalent recommended by NXP USA Inc. for new designs and production continuity.

Q: What packaging considerations apply to the substitute?

A: The MW6S004NT1 uses PLD-1.5 surface mount packaging supplied in Cut Tape (CT) and Digi-Reel® formats. The original NI-400S chassis mount package is replaced with a surface mount configuration requiring different assembly processes and board-level integration strategies.
