Substitute Part Grouping Explanation

Substitution of the LM4132EMF-1.8 is determined by strict equivalence across the following critical parameters:

• Output voltage specification: 1.8V fixed
• Output current capability: 20 mA
• Voltage tolerance: ±0.5%
• Temperature coefficient: 30ppm/°C
• Noise performance: 170µVp-p (0.1Hz to 10Hz)
• Input voltage range: 2.2V ~ 5.5V
• Supply current: 100µA
• Operating temperature range: -40°C ~ 125°C
• Package type: SOT-23-5 (SC-74A, SOT-753)
• Mounting type: Surface Mount

The substitute parts identified maintain identical electrical and mechanical specifications across all these parameters. Variations exist only in product status (Active vs. Obsolete), packaging format (Cut Tape, Tape & Reel), and RoHS compliance status.

Parameter Comparison

Engineering Selection Recommendations

For applications currently using the obsolete LM4132EMF-1.8, direct substitution with either LM4132EMF-1.8/NOPB or LM4132EMFX-1.8/NOPB is supported based on identical electrical and mechanical parameters.

LM4132EMF-1.8/NOPB is supplied in Cut Tape (CT) format and carries Active product status with ROHS3 compliance. This variant is suitable for standard procurement and assembly workflows.

LM4132EMFX-1.8/NOPB is supplied in Tape & Reel (TR) format and also carries Active product status with ROHS3 compliance. This variant is optimized for high-volume automated assembly operations.

Both substitute parts maintain full compatibility with existing designs without circuit modification. Selection between the two substitutes depends on procurement volume and assembly process requirements rather than electrical performance.

Frequently Asked Questions (FAQ)

Q: Can LM4132EMF-1.8/NOPB directly replace the obsolete LM4132EMF-1.8?

A: Yes. Both parts are electrically and mechanically identical across all specified parameters, including output voltage, tolerance, temperature coefficient, noise performance, and package type (SOT-23-5). The primary difference is product status (Active vs. Obsolete) and RoHS compliance.

Q: What is the difference between LM4132EMF-1.8/NOPB and LM4132EMFX-1.8/NOPB?

A: The electrical specifications are identical. The difference lies in packaging format: LM4132EMF-1.8/NOPB is supplied in Cut Tape (CT), while LM4132EMFX-1.8/NOPB is supplied in Tape & Reel (TR). Selection depends on assembly volume and automation requirements.

Q: Are there any circuit design changes required when substituting these parts?

A: No. All substitute parts maintain identical electrical characteristics, input/output voltage ranges, current specifications, and operating temperature ranges. Direct pin-for-pin substitution is supported without circuit modification.

Q: What does the "/NOPB" suffix indicate?

A: The "/NOPB" suffix indicates that the part is supplied without plumbum (lead-free), reflecting RoHS3 compliance. This is a packaging and compliance designation that does not affect electrical performance.

Q: Is the SOT-23-5 package compatible across all three part numbers?

A: Yes. All three part numbers use the identical SOT-23-5 package (SC-74A, SOT-753), ensuring mechanical and pin compatibility for PCB assembly and design layouts.

Q: What is the Moisture Sensitivity Level (MSL) for these parts?

A: All three parts carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.
