Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RN141GT2R is determined by the following critical parameters:

Primary Substitution Criteria:

• Diode Type: PIN - Single (functional equivalence)
• Voltage - Peak Reverse (Max): Minimum 50V (equal or higher acceptable)
• Current - Max: Minimum 100 mA (equal or higher acceptable)
• Capacitance @ Vr, F: 0.8pF @ 1V, 1MHz (electrical performance matching)
• Resistance @ If, F: 2Ohm @ 3mA, 100MHz (RF characteristics)
• Operating Temperature: Maximum 150°C (TJ) (thermal compatibility)
• RoHS Status: ROHS3 Compliant (regulatory requirement)

Package Compatibility Note: Physical package differences (VMD2 vs. SOD-923 vs. SOD-523) require PCB layout verification and may necessitate design modifications.

Parameter Comparison

Engineering Selection Recommendations

RN141CMT2R (Rohm Semiconductor): This part maintains identical electrical specifications to the RN141GT2R with matching voltage, current, capacitance, and resistance parameters. It is currently in active production status, ensuring long-term availability. The primary design consideration is the package transition from VMD2 to SOD-923, which requires PCB layout modification. This represents the most direct electrical equivalent.

BAP51-02,315 (NXP USA Inc.): This part provides higher voltage capability (60V) and extended temperature range (-65°C to 150°C). However, the maximum current rating is reduced to 50 mA, which may limit suitability for applications requiring the full 100 mA capability of the original part. The capacitance specification differs (0.35pF vs. 0.8pF), affecting RF performance characteristics. This part is in active production status. Package transition to SOD-523 requires PCB layout verification.

BAP51-02-TP (Micro Commercial Co): This part shares electrical specifications with BAP51-02,315 but is classified as obsolete, limiting its viability for new designs requiring long-term component availability. The resistance specification is provided (2.5Ohm @ 10mA, 100MHz), offering additional RF characterization data. Package transition to SOD-523 requires PCB layout verification.

Frequently Asked Questions (FAQ)

Q: Can RN141CMT2R directly replace RN141GT2R without circuit modifications?

A: RN141CMT2R provides identical electrical performance (50V, 100 mA, 0.8pF capacitance, 2Ohm resistance). However, the package change from VMD2 to SOD-923 requires PCB layout modification. Electrical circuit operation remains unchanged.

Q: What are the limitations of using BAP51-02,315 as a substitute?

A: BAP51-02,315 reduces maximum current from 100 mA to 50 mA and changes capacitance from 0.8pF to 0.35pF. These differences affect RF switching performance and power handling capability. Applications operating at or near 100 mA may experience performance degradation or thermal stress.

Q: Why is package selection important for substitution?

A: Package differences (VMD2, SOD-923, SOD-523) have different physical dimensions, lead configurations, and thermal characteristics. PCB layout, trace routing, and thermal management strategies must be verified for each package type to ensure proper circuit operation.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. RN141CMT2R, BAP51-02,315, and BAP51-02-TP are all ROHS3 compliant, meeting regulatory requirements for lead-free manufacturing and hazardous substance restrictions.

Q: Which substitute offers the best long-term availability?

A: RN141CMT2R and BAP51-02,315 are both in active production status, ensuring ongoing availability. BAP51-02-TP is obsolete and should be avoided for new designs requiring extended component lifecycle support.
