Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: LD39015M15R (STMicroelectronics)

The LD39015M15R is functionally equivalent with superior dropout voltage performance (0.1V @ 100mA versus 0.81V @ 150mA). This device extends the operating temperature range to 125°C and includes over-temperature protection in addition to over-current protection. The maximum input voltage specification of 5.5V is lower than the RP130N151A-TR-FE (6.5V), requiring verification that input supply voltages do not exceed 5.5V in the target application. All regulatory compliance certifications (RoHS3, EAR99, HTSUS) are equivalent. Product status is Active with 1517 units in stock.

Secondary Substitutes: S-1112B15MC-L6ATFU, S-1167A15-M5T1U, S-1167B15-M5T1U (ABLIC Inc.)

All three ABLIC devices maintain identical input voltage maximum (6.5V) and operating temperature range (-40°C to 85°C) specifications as the primary part. The S-1167 series (both A and B variants) demonstrate superior quiescent current performance (900 nA versus 58 µA), resulting in reduced power consumption during standby operation. The S-1167 series also features lower supply current maximum (16 µA versus 58 µA). The S-1112B15MC-L6ATFU offers the lowest quiescent current (1 µA) with moderate dropout voltage (0.55V @ 100mA). All ABLIC parts are ROHS3 compliant with REACH Unaffected status. Product status is Active for all three variants with inventory ranging from 793 to 1207 units.

Compliance and Regulatory Alignment:

All substitute parts maintain RoHS compliance (ROHS3 standard), MSL Level 1 (Unlimited moisture sensitivity), and identical export classification (EAR99) and tariff codes (HTSUS 8542.39.0001). No regulatory barriers exist for substitution.

Frequently Asked Questions (FAQ)

Q: Can the LD39015M15R be used as a direct replacement for the RP130N151A-TR-FE?

A: The LD39015M15R is functionally compatible with one critical constraint: the maximum input voltage is 5.5V compared to 6.5V for the RP130N151A-TR-FE. Direct substitution is valid only when the application input supply voltage does not exceed 5.5V. All other electrical specifications and package requirements are compatible.

Q: What is the primary advantage of the S-1167 series over the RP130N151A-TR-FE?

A: The S-1167A15-M5T1U and S-1167B15-M5T1U devices feature significantly lower quiescent current (900 nA versus 58 µA) and reduced supply current maximum (16 µA versus 58 µA). These characteristics result in lower power consumption during idle operation, making the S-1167 series preferable for battery-powered or low-power standby applications.

Q: Are all substitute parts available in the same package format?

A: All substitute parts are available in SOT-23-5 (SC-74A) surface mount package format, identical to the RP130N151A-TR-FE. PCB layout and component placement are directly compatible without modification.

Q: What is the difference between the S-1167A15-M5T1U and S-1167B15-M5T1U?

A: Both devices are electrically identical with matching specifications for output voltage (1.5V), output current (150mA), dropout voltage (0.58V @ 100mA), quiescent current (900 nA), and PSRR (70dB @ 1kHz). The designation difference (A versus B variant) reflects manufacturing or packaging variations without functional impact on electrical performance.

Q: Does the LD39015M15R provide additional protection features?

A: The LD39015M15R includes over-temperature protection in addition to over-current protection, whereas the RP130N151A-TR-FE provides over-current protection only. This additional thermal protection enhances device reliability in high-temperature operating environments.

Q: What is the impact of dropout voltage differences between substitute parts?

A: Dropout voltage determines the minimum input-to-output voltage differential required for proper regulation. The LD39015M15R (0.1V @ 100mA) requires the smallest differential, while the RP130N151A-TR-FE (0.81V @ 150mA) requires the largest. Lower dropout voltage allows operation with lower input supply voltages or provides greater headroom for input voltage variations.

Q: Are all substitute parts RoHS compliant?

A: All substitute parts are RoHS compliant. The RP130N151A-TR-FE carries RoHS Compliant status, while all substitute parts carry ROHS3 Compliant status, representing equivalent environmental compliance standards.

Q: Can packaging format be mixed within a single design?

A: All substitute parts use identical SOT-23-5 (SC-74A) package format. However, the RP130N151A-TR-FE is supplied in Tape & Reel (TR) format, while S-1112B15MC-L6ATFU, S-1167A15-M5T1U, and S-1167B15-M5T1U are supplied in Cut Tape (CT) format. The LD39015M15R is supplied in Tape & Reel (TR) format. Packaging format does not affect component electrical performance or PCB compatibility.
