Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CSRN2512FTR470 is determined by strict equivalence across the following parameters:

• Resistance value: 470 mOhms
• Tolerance: ±1%
• Power rating: 2W
• Package: 2512 (6432 Metric)
• Composition: Thick Film
• Temperature coefficient: ±200ppm/°C
• Operating temperature range: -55°C ~ 155°C
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity: MSL 1

The RLP73K3AR47FTDF from TE Connectivity Passive Product meets all these criteria and qualifies as a direct substitute. Both parts share identical electrical specifications and package dimensions, enabling direct replacement in circuit designs.

Parameter Comparison

Engineering Selection Recommendations

Both the CSRN2512FTR470 and RLP73K3AR47FTDF are active production parts with ROHS3 compliance and identical electrical specifications. The RLP73K3AR47FTDF offers higher inventory availability (16,602 pieces) compared to the CSRN2512FTR470 (775 pieces), making it suitable for high-volume applications or extended lead time mitigation. The maximum seated height difference of 0.005" (0.14mm) between the two parts is negligible for standard PCB assembly processes and does not affect circuit performance or board layout compatibility.

Frequently Asked Questions (FAQ)

Q: Can the RLP73K3AR47FTDF replace the CSRN2512FTR470 in automotive applications?

A: Yes. Both parts carry identical electrical specifications, operate across the same temperature range (-55°C ~ 155°C), and are ROHS3 compliant. The RLP73K3AR47FTDF is qualified for current sense applications and meets the same performance requirements.

Q: Are there any physical compatibility concerns between these parts?

A: Both parts use the 2512 (6432 Metric) package with identical length and width dimensions (0.250" x 0.124"). The maximum seated height differs by 0.005" (0.14mm), which does not impact PCB assembly or component placement.

Q: What is the significance of the ±200ppm/°C temperature coefficient?

A: The temperature coefficient defines the resistance change per degree Celsius across the operating range. Both parts maintain ±200ppm/°C, ensuring stable performance in thermal cycling and high-temperature automotive environments.

Q: Are both parts suitable for current sensing applications?

A: Yes. Both the CSRN2512FTR470 and RLP73K3AR47FTDF are specified as current sense thick film resistors with 470 mOhms resistance and ±1% tolerance, meeting precision requirements for current monitoring circuits.

Q: What does MSL 1 (Unlimited) mean for moisture sensitivity?

A: MSL 1 indicates the lowest moisture sensitivity level, meaning the parts do not require special moisture control during storage or handling. They can be stored under standard conditions without desiccant packaging.
