Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CSRN2512FTR430 is determined by strict equivalence across the following parameters:

• Resistance value: 430 mOhms
• Tolerance: ±1%
• Power rating: 2W
• Package type: 2512 (6432 Metric)
• Composition: Thick Film
• Temperature coefficient: ±200ppm/°C
• Operating temperature range: -55°C ~ 155°C
• Termination count: 2
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity level: 1 (Unlimited)

The RLP73K3AR43FTDF from TE Connectivity Passive Product meets all these electrical and mechanical parameters and qualifies as a direct substitute.

Parameter Comparison

Engineering Selection Recommendations

Both the CSRN2512FTR430 and RLP73K3AR43FTDF are active production parts with ROHS3 compliance and REACH unaffected status. Selection between these parts should be based on availability and supply chain requirements. The RLP73K3AR43FTDF offers higher inventory availability (2934 pieces) compared to the CSRN2512FTR430 (698 pieces). The seated height difference of 0.005" (0.14mm) between the two parts is within typical PCB assembly tolerances for 2512 package components and does not affect electrical performance or functional compatibility.

Frequently Asked Questions (FAQ)

Q: Can RLP73K3AR43FTDF be used as a direct replacement for CSRN2512FTR430?

A: Yes. Both parts share identical electrical specifications (430 mOhms ±1%, 2W, ±200ppm/°C) and mechanical package (2512 / 6432 Metric). Both are ROHS3 compliant with MSL 1 rating.

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

A: The CSRN2512FTR430 has a maximum seated height of 0.028" (0.70mm), while the RLP73K3AR43FTDF measures 0.033" (0.84mm). This 0.005" (0.14mm) difference is within standard PCB assembly clearance specifications for 2512 package resistors and does not impact circuit performance or board layout compatibility.

Q: Are both parts suitable for automotive applications?

A: The CSRN2512FTR430 carries AEC-Q200 automotive qualification. The RLP73K3AR43FTDF does not list AEC-Q200 in the provided specifications. For applications requiring explicit AEC-Q200 compliance, the CSRN2512FTR430 is the specified choice.

Q: What packaging format is used for these parts?

A: Both parts are supplied in Tape & Reel (TR) format, standard for automated PCB assembly processes.

Q: Are there any compliance or regulatory differences between these parts?

A: Both parts are ROHS3 compliant, REACH unaffected, and carry the same ECCN (EAR99) and HTSUS (8533.21.0030) classifications.
