**Short answer:** SRP1038A-R36M is a Bourns SRP1038A-series shielded power inductor: 0.36 µH ±20 % (100 kHz, 1 V), DCR 1.05 mΩ typical / 1.2 mΩ maximum, Irms 31 A, Isat 60 A (20 % inductance drop), body 11.0 × 10.0 × 3.8 mm. Values below are from Bourns' SRP1038A datasheet. Check that document before ordering; it is the reference, not this page.
Key datasheet values (Bourns SRP1038A Series datasheet)

| SRF | 105 MHz typ | |
| DCR | 1.05 mΩ typ, 1.2 mΩ max | |
| Irms | 31 A | Temperature rise 40 °C at rated Irms |
| Isat | 60 A | Inductance drops 20 % at Isat |
| Operating temperature | –55 °C to +150 °C | Temperature rise included |
| Storage temperature | –55 °C to +150 °C | |
| Dimensions | 11.0 ±0.5 × 10.0 ±0.3 mm, height 3.8 ±0.2 mm | |

Electrical specifications are at 25 °C. The series spans 0.20 to 47 µH. Bourns shows two terminal styles (non-lead-frame and lead-frame) with separate drawings, so confirm the terminal type and recommended layout for -R36M in the datasheet.
Cross-reference candidates in the MST store (to verify, not equivalents)
The MST store lists two MAZO 0.36 µH parts in a similar ~11 × 10 mm class. Values are from the MAZO datasheets linked on each product page:
| Parameter | Bourns SRP1038A-R36M | MAZO [LPCA-1040-R36-M](/store/mazo-power-inductors/LPCA-1040-R36-M) | MAZO [VCMA-1040-R36-M-1A](/store/mazo-power-inductors/VCMA-1040-R36-M-1A) |
|---|---|---|---|
| Inductance | 0.36 µH ±20 % @ 100 kHz, 1 V | 0.36 µH ±20 % @ 1 MHz, 1.0 V | 0.36 µH ±20 % @ 1 MHz, 1.0 V |
| DCR typ / max | 1.05 / 1.2 mΩ | 1.05 / 1.2 mΩ | 0.95 / 1.2 mΩ |
| Saturation current | 60 A (20 % drop) | 50 A typ (about 30 % drop) | 54 A typ, 50 A max column (about 30 % drop) |
| Heating current | 31 A (40 °C rise) | 30 A typ (about 40 °C rise) | 32 A typ, 30 A max column (about 40 °C rise) |
| Size | 11.0 × 10.0 × 3.8 mm | 11.5 × 10.3 × 4.0 mm max | 11.5 × 10.3 × 4.0 mm max |
| Operating temperature | –55 to +150 °C | –55 to +125 °C | –55 to +125 °C |
| AEC-Q200 | Yes | Not stated | Yes |
What this shows:
- **Not equivalent on the datasheets.** The saturation currents use different definitions (20 % vs about 30 % drop), so 60 A vs 50/54 A cannot be compared directly. Inductance is tested at different frequencies.
- **The MAZO parts are larger and taller** (4.0 mm max vs 3.8 ±0.2 mm), and their maximum operating temperature is lower (125 °C vs 150 °C). Check height clearance, land pattern and thermal margin.
- DCR maxima match (1.2 mΩ), and the heating currents are in the same range at a similar 40 °C rise.
Interchangeability has **not** been established. These are candidates to verify on your board, under your current waveform and temperature.
What to send in an RFQ
1. Full part number (SRP1038A-R36M), quantity, and whether full reels are required.
2. Genuine Bourns only, or open to an alternative for evaluation.
3. If an alternative is acceptable: peak and RMS current, switching frequency, ambient temperature, height limit and land pattern.
