Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RLP73M1ER082FTDF is determined by the following critical parameters:

Electrical Specifications:

• Resistance value: 82 mOhms
• Tolerance: ±1%
• Power rating: 0.125W (1/8W)
• Operating temperature range: -55°C to 155°C
• Composition: Thick Film

Mechanical Specifications:

• Package type: 0402 (1005 Metric)
• Number of terminations: 2
• Physical dimensions compatible with 0402 footprint

Compliance & Environmental:

• RoHS3 compliance
• Moisture Sensitivity Level 1

The UCR01MVPFSR082 from Rohm Semiconductor meets all electrical and mechanical substitution criteria. Both parts share identical resistance, tolerance, power rating, package designation, and operating temperature range. Both are RoHS3 compliant with MSL 1 rating. The substitute part includes additional AEC-Q200 automotive qualification, which does not restrict its use in non-automotive applications.

Parameter Comparison

Engineering Selection Recommendations

Both the RLP73M1ER082FTDF and UCR01MVPFSR082 are Active status components with full RoHS3 compliance and unlimited moisture sensitivity rating. Selection between these parts is based on application requirements and supply chain considerations.

The RLP73M1ER082FTDF from TE Connectivity is suitable for general industrial current sense applications requiring standard thick film resistor performance within the specified temperature range.

The UCR01MVPFSR082 from Rohm Semiconductor provides identical electrical and mechanical performance with additional AEC-Q200 automotive qualification. This qualification indicates enhanced reliability testing and quality assurance protocols. The substitute part is suitable for both automotive and non-automotive applications where the original part is specified.

Both parts are available in Tape & Reel packaging and share identical 0402 footprint compatibility, enabling direct board-level substitution without layout modifications.

Frequently Asked Questions (FAQ)

Q: Can UCR01MVPFSR082 be used as a direct replacement for RLP73M1ER082FTDF?

A: Yes. Both parts have identical resistance (82 mOhms), tolerance (±1%), power rating (0.125W), package (0402), composition (thick film), and operating temperature range (-55°C to 155°C). Both are RoHS3 compliant with MSL 1 rating. The substitute part is electrically and mechanically compatible for direct substitution.

Q: What is the significance of AEC-Q200 qualification on the substitute part?

A: AEC-Q200 is an automotive industry standard qualification that certifies enhanced reliability testing and quality assurance. This qualification does not restrict the part's use in non-automotive applications. It indicates the substitute part meets or exceeds the reliability requirements of the original part.

Q: Are there dimensional differences between these parts?

A: Both parts use the 0402 (1005 Metric) package. The main part dimensions are 0.039" L x 0.020" W (1.00mm x 0.50mm) with maximum seated height of 0.017" (0.43mm). The substitute part dimensions are 0.039" L x 0.022" W (1.00mm x 0.55mm) with identical maximum seated height of 0.017" (0.43mm). The width difference of 0.05mm is within 0402 package tolerance and does not affect PCB footprint compatibility.

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

A: The RLP73M1ER082FTDF specifies ±400ppm/°C temperature coefficient. The UCR01MVPFSR082 specifies 0/+300ppm/°C temperature coefficient. The substitute part exhibits lower temperature coefficient variation, which provides improved stability across the operating temperature range.

Q: Are both parts available in the same packaging format?

A: Yes. Both parts are supplied in Tape & Reel (TR) packaging, enabling compatibility with automated assembly processes and identical handling requirements.

Q: Can these parts be used interchangeably in existing designs?

A: Yes. The electrical specifications, mechanical package, and compliance certifications are equivalent. Direct substitution on PCBs designed for the RLP73M1ER082FTDF is supported without design modifications.
