Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the CSRN2512JTR430 are qualified based on the following critical parameters:

• Resistance value: 430 mOhms (exact match required)
• Power rating: 2W (exact match required)
• Package: 2512 (6432 Metric) (exact match required)
• Composition: Thick Film (exact match required)
• Temperature coefficient: ±200ppm/°C (exact match required)
• Operating temperature range: -55°C ~ 155°C (exact match required)
• RoHS and environmental compliance: ROHS3 Compliant, REACH Unaffected

Tolerance may vary between direct equivalents and upgrade options. Direct substitutes maintain ±5% tolerance, while upgrade options offer tighter ±1% tolerance for applications requiring higher precision.

Parameter Comparison

Engineering Selection Recommendations

RLP73K3AR43JTE serves as a direct functional equivalent to CSRN2512JTR430. Both parts maintain identical electrical specifications (430 mOhms, ±5% tolerance, 2W power rating) and mechanical compatibility within the 2512 package. Both are active products with ROHS3 compliance and unlimited moisture sensitivity rating, suitable for equivalent circuit implementations.

RLP73K3AR43FTDF represents an upgrade option with tighter ±1% tolerance specification while maintaining all other electrical and mechanical parameters. This upgrade is applicable in designs where improved resistance accuracy is required without package or thermal characteristic changes. The upgrade part is also active and fully compliant with environmental standards.

Height variation between the main part (0.028" maximum seated height) and both TE Connectivity substitutes (0.033" maximum seated height) must be evaluated for applications with strict PCB clearance constraints.

Frequently Asked Questions (FAQ)

Q: Can RLP73K3AR43JTE replace CSRN2512JTR430 in existing designs?

A: Yes. RLP73K3AR43JTE is a direct substitute with identical resistance (430 mOhms), tolerance (±5%), power rating (2W), package (2512), temperature coefficient (±200ppm/°C), and operating range (-55°C ~ 155°C). Both are thick film current sense resistors with ROHS3 compliance. The 0.005" difference in maximum seated height (0.033" vs 0.028") must be verified against PCB layout constraints.

Q: What is the difference between RLP73K3AR43JTE and RLP73K3AR43FTDF?

A: The primary difference is tolerance specification. RLP73K3AR43JTE maintains ±5% tolerance matching the original part, while RLP73K3AR43FTDF offers ±1% tolerance for higher precision applications. All other parameters including resistance value, power rating, package, temperature coefficient, and operating range are identical.

Q: Are all three parts suitable for automotive applications?

A: CSRN2512JTR430 carries explicit AEC-Q200 automotive qualification. RLP73K3AR43JTE and RLP73K3AR43FTDF are specified as current sense thick film resistors with active product status and full environmental compliance (ROHS3, REACH Unaffected). Automotive qualification status for the TE Connectivity parts should be confirmed against specific application requirements.

Q: What is the significance of the 2512 package designation?

A: The 2512 package (6432 Metric) is a standard chip resistor footprint measuring 0.250" L x 0.124" W (6.35mm x 3.15mm). All three parts use this identical package, ensuring mechanical and electrical compatibility on PCBs designed for 2512 components.

Q: Can these parts be used interchangeably in current sense applications?

A: Yes, all three parts are specified for current sense applications with thick film composition and identical temperature coefficients (±200ppm/°C). The choice between direct equivalent (RLP73K3AR43JTE) and upgrade (RLP73K3AR43FTDF) depends on circuit accuracy requirements.
