Key Parameters

Substitute Part Grouping Explanation

Substitution of the FP0705R3-R07-R is determined by strict alignment of the following electrical and mechanical parameters:

Critical Matching Parameters:

• Inductance value: 72 nH (tolerance variations acceptable within design margin)
• Package footprint: 7.00mm x 7.00mm surface mount
• Shielding configuration: Unshielded
• Current rating: Minimum 31 A (acceptable for applications rated at 32 A with thermal margin)
• Saturation current: Minimum 50 A (acceptable for applications rated at 65 A with design margin)
• DC resistance: Lower values acceptable (0.27 mOhm vs. 0.46 mOhm reduces power dissipation)
• Operating temperature range: Minimum -40°C to 125°C coverage
• Mounting type: Surface mount, tape and reel packaging
• Compliance: RoHS compliant

The PA1512.700NLT from Pulse Electronics meets these substitution criteria with equivalent inductance, identical package dimensions, and compatible electrical ratings within acceptable engineering margins.

Engineering Selection Recommendations

Primary Part: FP0705R3-R07-R

The FP0705R3-R07-R remains the primary selection for applications requiring the specified 32 A current rating and 65 A saturation current. This part is active in production, RoHS compliant, and available in quantity (1057 pcs in stock). The ±10% inductance tolerance provides tighter specification control for precision circuit designs.

Substitute Part: PA1512.700NLT

The PA1512.700NLT from Pulse Electronics is a qualified substitute for applications where:

• Operating current does not exceed 31 A continuous
• Saturation current requirements do not exceed 50 A
• Lower DC resistance (0.27 mOhm vs. 0.46 mOhm) is beneficial for reducing thermal dissipation
• Wider inductance tolerance (±20%) is acceptable within circuit design margins
• Extended temperature operation to 130°C is required

The substitute part is active in production, ROHS3 compliant, and available in higher quantity (1781 pcs in stock). Identical package footprint (7.00mm x 7.00mm) ensures direct PCB compatibility without layout modifications.

Frequently Asked Questions (FAQ)

Q: Can PA1512.700NLT replace FP0705R3-R07-R in all applications?

A: No. The PA1512.700NLT has lower current and saturation ratings (31 A and 50 A respectively versus 32 A and 65 A). Substitution is valid only for applications operating at or below these lower ratings. Review circuit current requirements before substitution.

Q: What is the impact of the different inductance tolerances (±10% vs. ±20%)?

A: The FP0705R3-R07-R has tighter tolerance (±10%), providing more precise inductance values. The PA1512.700NLT tolerance of ±20% is wider. For circuits with tight inductance specifications, the primary part is preferred. For general-purpose applications, the wider tolerance is typically acceptable.

Q: Does the lower DC resistance of PA1512.700NLT affect circuit performance?

A: Lower DC resistance (0.27 mOhm vs. 0.46 mOhm) reduces resistive losses and power dissipation. This is generally beneficial and does not negatively impact circuit function. Thermal performance improves with the substitute part.

Q: Are the package dimensions truly identical?

A: The footprints are identical (7.00mm x 7.00mm). Height differs by 0.01mm (4.95mm vs. 4.96mm), which is negligible for surface mount assembly and does not require PCB layout changes.

Q: Can I use PA1512.700NLT if my application requires -40°C to 125°C operation?

A: Yes. The PA1512.700NLT operates from -40°C to 130°C, which fully covers the -40°C to 125°C requirement. The substitute part exceeds the temperature specification.

Q: Are both parts RoHS compliant?

A: Yes. The FP0705R3-R07-R is RoHS compliant. The PA1512.700NLT is ROHS3 compliant, which represents the current RoHS standard. Both parts meet regulatory requirements.

Q: What is the tape and reel packaging specification for both parts?

A: Both parts are supplied in tape and reel (TR) packaging, standard for surface mount component distribution. Packaging is compatible for automated assembly processes.
