Key Parameters

Substitute Part Grouping Explanation

The RLP73K3AR15FTDF from TE Connectivity Passive Product qualifies as a direct substitute based on the following critical parameters:

• Resistance value: 150 mOhms (identical)
• Tolerance: ±1% (identical)
• Power rating: 2W (identical)
• Package: 2512 (6432 Metric) (identical)
• Composition: Thick Film (identical)
• Temperature coefficient: ±200ppm/°C (identical)
• Operating temperature range: -55°C ~ 155°C (identical)
• Packaging format: Tape & Reel (TR) (identical)
• RoHS compliance: ROHS3 Compliant (identical)
• Moisture sensitivity: 1 (Unlimited) (identical)

Both parts meet automotive current sense applications with equivalent electrical performance and mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both the CSRN2512FTR150 and RLP73K3AR15FTDF are active production parts with ROHS3 compliance and identical electrical specifications. Selection between these parts should be based on:

• Availability and lead time requirements
• Supplier relationship and pricing
• PCB layout constraints, noting the maximum seated height difference of 0.005" (0.14mm) between parts
• Existing qualification status within your design documentation

The RLP73K3AR15FTDF offers higher inventory availability (30903 pieces) compared to the CSRN2512FTR150 (1018 pieces), which may influence procurement decisions for high-volume applications.

Frequently Asked Questions (FAQ)

Q: Can RLP73K3AR15FTDF be used as a direct replacement for CSRN2512FTR150?

A: Yes. Both parts share identical electrical specifications (150 mOhms, ±1%, 2W), composition (thick film), temperature characteristics (±200ppm/°C, -55°C to 155°C), and package format (2512 Tape & Reel). Both are ROHS3 compliant with MSL 1 rating.

Q: Are there any physical differences between these parts?

A: The maximum seated height differs slightly: CSRN2512FTR150 is 0.028" (0.70mm) while RLP73K3AR15FTDF is 0.033" (0.84mm). This 0.005" (0.14mm) difference is within typical PCB assembly tolerances but should be verified for space-constrained layouts.

Q: Do both parts meet automotive requirements?

A: The CSRN2512FTR150 carries explicit AEC-Q200 qualification. The RLP73K3AR15FTDF is specified for current sense applications with equivalent temperature and operating range specifications. Confirm AEC-Q200 status with TE Connectivity for your specific application requirements.

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

A: The 2512 package (6432 Metric) is a standard surface-mount resistor size measuring 0.250" L x 0.124" W (6.35mm x 3.15mm). Both substitute parts use identical package dimensions, ensuring mechanical compatibility with existing PCB designs.

Q: Are there supply or inventory considerations?

A: The RLP73K3AR15FTDF has significantly higher inventory availability (30903 pieces) compared to CSRN2512FTR150 (1018 pieces), which may impact lead times and procurement strategy for volume production.
