RN142GT2R Equivalent & Substitute Parts

Part Overview

The RN142GT2R is an RF PIN diode manufactured by Rohm Semiconductor, rated for 60V peak reverse voltage with 100 mA maximum current in a VMD2 package (SOD-723). This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement.

PIN diodes are used in RF switching, attenuator, and modulation applications where low capacitance and controlled resistance characteristics are required. The RN142GT2R's electrical specifications define its operational envelope and determine which alternative parts can serve as functional replacements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RN142GT2R is determined by the following criteria:

Primary Electrical Requirements:

• Voltage - Peak Reverse (Max): Must equal or exceed 60V
• Current - Max: Must equal or exceed 100 mA
• Diode Type: Must be PIN - Single configuration
• Capacitance and Resistance: Must be compatible with RF circuit performance at operating frequency

Secondary Considerations:

• Operating Temperature: Must support 150°C junction temperature or higher
• RoHS and REACH Compliance: Must maintain ROHS3 and REACH Unaffected status
• Package compatibility: Physical form factor may differ if circuit board layout permits

Identified Substitute Groups:

Group 1 - Direct Electrical Match (60V, 100 mA):

• RN142SMT2R (Rohm Semiconductor): Same electrical specifications, different package (SOD-523/EMD2)

Group 2 - Reduced Current Rating (60V, 50 mA):

• BAP51-02,115 (NXP Semiconductors)
• BAP51-02,315 (NXP USA Inc.)
• BAP51-02-TP (Micro Commercial Co)

These parts meet the 60V voltage requirement but are rated for 50 mA maximum current, which is below the original 100 mA specification.

Group 3 - Reduced Voltage Rating (30V, 100 mA):

• BAP65-02,115 (NXP Semiconductors)
• BAP65-02,135 (NXP USA Inc.)

These parts support the full 100 mA current but are rated for only 30V peak reverse voltage, which is below the original 60V specification.

Parameter Comparison

Engineering Selection Recommendations

Preferred Substitute: RN142SMT2R

RN142SMT2R is the optimal substitute for RN142GT2R. It maintains identical electrical specifications (60V, 100 mA, 0.45pF capacitance, 2Ohm resistance) and is manufactured by the same supplier (Rohm Semiconductor). The only difference is the package form factor (SOD-523/EMD2 versus SOD-723/VMD2). RN142SMT2R holds Active product status with 21,200 units in stock, ensuring long-term availability. Full ROHS3 compliance and REACH Unaffected status are maintained.

Alternative Substitutes with Electrical Derating:

BAP51-02,115 and BAP51-02,315 (NXP Semiconductors) are Active products suitable for applications where the 100 mA current requirement can be reduced to 50 mA. Both maintain the 60V voltage rating and offer improved temperature range (-65°C to 150°C). BAP51-02,315 provides higher inventory availability (60,400 units) compared to BAP51-02,115 (15,645 units).

BAP65-02,115 and BAP65-02,135 (NXP Semiconductors) are Active products suitable for applications where the 60V voltage requirement can be reduced to 30V while maintaining the full 100 mA current rating. Both offer extended temperature range and improved forward resistance characteristics (350mOhm at 100mA).

Avoid: BAP51-02-TP is classified as Obsolete and should not be selected for new designs despite electrical compatibility.

Frequently Asked Questions (FAQ)

Q: Can RN142SMT2R directly replace RN142GT2R without circuit modification?

A: RN142SMT2R provides identical electrical performance. The primary consideration is package compatibility. RN142GT2R uses SOD-723 (VMD2) while RN142SMT2R uses SOD-523 (EMD2). Both are surface-mount packages with different footprints. Circuit board layout and PCB design must accommodate the SOD-523 package dimensions.

Q: What is the difference between BAP51-02,115 and BAP51-02,315?

A: Both parts are electrically identical 60V, 50 mA PIN diodes from NXP. The primary difference is packaging: BAP51-02,115 is supplied in Cut Tape (CT) and Digi-Reel format, while BAP51-02,315 is supplied in Tape & Reel (TR) format. BAP51-02,315 offers significantly higher inventory availability (60,400 units versus 15,645 units).

Q: Can BAP65-02,115 or BAP65-02,135 be used as direct replacements?

A: BAP65 series parts are suitable only if the application circuit operates at 30V or lower peak reverse voltage. These parts cannot be used in circuits requiring the full 60V rating of the original RN142GT2R. The 100 mA current capability is maintained, and forward resistance is improved at high current levels.

Q: Can BAP51-02,115 be used if the application requires 100 mA?

A: BAP51-02,115 is rated for 50 mA maximum current. Using this part in a 100 mA application exceeds its electrical rating and will result in component failure or degraded performance. This substitution is valid only if the circuit design can be modified to operate at 50 mA or lower.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 Compliant status and REACH Unaffected designation, matching the environmental compliance profile of the original RN142GT2R.

Q: What is the temperature operating range difference?

A: RN142GT2R specifies 150°C maximum junction temperature without a minimum. NXP substitute parts (BAP51 and BAP65 series) specify -65°C to 150°C operating range, providing extended low-temperature capability. This difference is not a limitation for standard industrial applications.
