Substitute Part Grouping Explanation

Substitution eligibility for the RLP73V2BR015FTDF is determined by strict alignment of the following parameters:

Electrical Specifications:

• Resistance value: 15 mOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 0.5W minimum (equal or higher acceptable)
• Composition: Thick film (required for current sense application)
• Operating temperature range: -55°C to +155°C minimum (equal or wider range acceptable)

Mechanical Specifications:

• Package: 1206 (3216 Metric) form factor (exact match required)
• Termination count: 2 (exact match required)
• Height seated maximum: 0.026" (0.65mm) or less (required for PCB clearance compatibility)

Compliance & Certification:

• RoHS3 compliance (required for regulatory alignment)
• MSL 1 rating (required for moisture protection equivalence)
• REACH unaffected status (required for supply chain consistency)

The UCR18EVHFSR015 manufactured by Rohm Semiconductor meets all substitution criteria and is classified as an equivalent substitute part.

Frequently Asked Questions (FAQ)

Q: Can the UCR18EVHFSR015 directly replace the RLP73V2BR015FTDF on existing PCBs?

A: Yes. Both components share identical 1206 (3216 Metric) package dimensions, 0.026" maximum seated height, and two-terminal configuration. No PCB layout modifications are required for direct substitution.

Q: What is the significance of the temperature coefficient difference between these parts?

A: The RLP73V2BR015FTDF specifies ±600ppm/°C while the UCR18EVHFSR015 specifies 0/+350ppm/°C. The substitute part exhibits lower temperature-dependent resistance variation, resulting in improved current sensing accuracy across the -55°C to +155°C operating range. This enhanced stability is particularly beneficial in precision measurement applications.

Q: Are both parts compliant with RoHS3 and REACH regulations?

A: Yes. Both the RLP73V2BR015FTDF and UCR18EVHFSR015 are RoHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic component manufacturing and distribution.

Q: What does AEC-Q200 qualification on the UCR18EVHFSR015 indicate?

A: AEC-Q200 is an automotive electronics council qualification standard for passive components. The UCR18EVHFSR015 meets automotive-grade reliability and performance requirements, making it suitable for automotive and automotive-equivalent applications. The RLP73V2BR015FTDF does not carry this automotive qualification.

Q: Is the MSL 1 rating identical for both components?

A: Yes. Both parts carry MSL 1 (Unlimited) moisture sensitivity level rating, indicating equivalent moisture protection and unlimited shelf life under standard storage conditions without desiccant requirements.

Q: Can these 15 milliohm resistors be used interchangeably in current sensing circuits?

A: Yes. Both components meet identical electrical specifications (15 mOhms ±1%, 0.5W, thick film composition) and mechanical requirements (1206 package, 2 terminations). They function identically in current sensing applications within the specified operating temperature range.

Q: What is the difference in physical dimensions between these parts?

A: The RLP73V2BR015FTDF measures 0.122" L × 0.061" W (3.10mm × 1.55mm), while the UCR18EVHFSR015 measures 0.126" L × 0.063" W (3.20mm × 1.60mm). Both fit within standard 1206 package tolerances and are mechanically compatible with identical PCB footprints. Maximum seated height is identical at 0.026" (0.65mm).
