Parameter Comparison

Engineering Selection Recommendations

P0751.102NLT (Pulse Electronics) qualifies as a direct substitute for UP2UC-1R0-R. Both components share identical inductance (1 µH), current rating (6.8 A), and saturation current (9 A) specifications. The DCR maximum of 10 mOhm in the P0751.102NLT is within acceptable tolerance relative to the 9 mOhm specification of the UP2UC-1R0-R. Both parts maintain Active product status and comply with RoHS3 standards. The P0751.102NLT offers extended operating temperature range (-40°C ~ 130°C) compared to the UP2UC-1R0-R (-25°C ~ 85°C). Physical dimensions are comparable with minor variations in length and height. Inventory availability is higher for the P0751.102NLT (1880 Pcs vs. 681 Pcs).

SDR1005-1R0ML (Bourns Inc.) qualifies as a substitute with performance advantages. This component exceeds the primary electrical requirements with 7.5 A current rating versus the 6.8 A requirement, and provides superior DC resistance performance at 7 mOhm maximum. The SDR1005-1R0ML features a ferrite drum core construction with documented Q factor (55 @ 2.6MHz) and higher self-resonant frequency (137 MHz). Operating temperature range extends to -40°C ~ 125°C. Physical dimensions match the UP2UC-1R0-R footprint (0.500" L x 0.394" W), with slightly reduced height (0.197" vs. 0.205"). Both parts maintain Active status and ROHS3 compliance. Inventory availability is highest for SDR1005-1R0ML (2299 Pcs).

Selection between substitute parts depends on application-specific requirements for operating temperature range, DC resistance tolerance, and core material performance characteristics.

Frequently Asked Questions (FAQ)

Q: Can P0751.102NLT replace UP2UC-1R0-R in all applications?

A: P0751.102NLT meets the electrical substitution criteria with matching inductance (1 µH), current rating (6.8 A), and saturation current (9 A). The 10 mOhm maximum DCR is within acceptable tolerance of the 9 mOhm specification. Physical dimensions are comparable. Substitution is valid for applications operating within the overlapping temperature range (-25°C ~ 85°C). Applications requiring the full -40°C ~ 130°C range of P0751.102NLT will benefit from extended thermal capability.

Q: What are the advantages of SDR1005-1R0ML over UP2UC-1R0-R?

A: SDR1005-1R0ML provides superior electrical performance with 7.5 A current rating (versus 6.8 A) and lower DC resistance at 7 mOhm maximum (versus 9 mOhm). The ferrite drum core construction delivers documented Q factor performance (55 @ 2.6MHz) and higher self-resonant frequency (137 MHz). Extended operating temperature range (-40°C ~ 125°C) accommodates wider thermal environments. Physical footprint compatibility is maintained with identical length and width dimensions.

Q: Are there mechanical compatibility concerns when substituting these parts?

A: All three inductors are surface mount components with nonstandard package configurations. Physical dimensions are comparable: UP2UC-1R0-R and SDR1005-1R0ML share identical length and width (0.500" L x 0.394" W), while P0751.102NLT dimensions are 0.510" L x 0.370" W. Height variations are minimal (0.197" to 0.215"). PCB layout and solder reflow profiles should be verified for the specific substitute selected, particularly regarding height clearance and thermal management requirements.

Q: Do all substitute parts meet RoHS compliance requirements?

A: Yes. UP2UC-1R0-R is RoHS Compliant. Both P0751.102NLT and SDR1005-1R0ML are ROHS3 Compliant, which represents the current RoHS standard. All three components are classified as EAR99 for export control purposes and share the same HTSUS code (8504.50.4000).

Q: What is the moisture sensitivity level for these inductors?

A: All three components are rated MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. These parts can be stored and handled without special moisture control measures.

Q: How do the inductance test frequencies differ between these parts?

A: UP2UC-1R0-R and P0751.102NLT are tested at 100 kHz, while SDR1005-1R0ML is tested at 1 kHz. This difference reflects different measurement methodologies but does not affect the 1 µH nominal inductance value or ±20% tolerance specification common to all three parts.
