Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following critical parameters: resistance value (270 mOhms), power rating (2W), package type (2512), composition (thick film), temperature coefficient (±200ppm/°C), and operating temperature range (-55°C ~ 155°C). All identified substitutes maintain these core specifications.

Substitutes are grouped into two categories:

Tolerance Upgrade (±5% to ±1%): CSRN2512FTR270 and RLP73K3AR27FTDF provide improved tolerance specifications while maintaining all other electrical and mechanical parameters.

Direct Equivalent (±5% tolerance): RLP73K3AR27JTE provides cross-manufacturer equivalence with identical tolerance and electrical characteristics.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts maintain active product status and full ROHS3 compliance. Selection between substitutes depends on tolerance requirements and manufacturer preference.

For applications requiring standard ±5% tolerance, CSRN2512JTR270 and RLP73K3AR27JTE are functionally equivalent. CSRN2512JTR270 is the original specification; RLP73K3AR27JTE provides cross-manufacturer sourcing from TE Connectivity Passive Product.

For applications requiring improved ±1% tolerance, CSRN2512FTR270 (Stackpole) and RLP73K3AR27FTDF (TE Connectivity) are direct upgrades. Both maintain identical power rating, package, and operating temperature specifications while providing tighter tolerance control.

All parts carry AEC-Q200 automotive qualification (where specified in original data) and unlimited moisture sensitivity rating, suitable for automotive current sense applications.

Frequently Asked Questions (FAQ)

Q: Can CSRN2512FTR270 replace CSRN2512JTR270 in my design?

A: Yes. CSRN2512FTR270 is a direct upgrade with identical electrical and mechanical specifications except for improved tolerance (±1% vs ±5%). All other parameters including resistance value, power rating, package, temperature coefficient, and operating range are identical.

Q: What is the difference between Stackpole and TE Connectivity substitutes?

A: Both manufacturers provide equivalent parts with identical resistance, power rating, package, and operating specifications. The primary differences are manufacturer identity and inventory availability. Stackpole parts (CSRN series) and TE Connectivity parts (RLP73 series) are functionally interchangeable within their respective tolerance grades.

Q: Are the physical dimensions identical across all substitutes?

A: The package type (2512 / 6432 Metric) is identical for all parts. Length and width are 0.250" × 0.124" (6.35mm × 3.15mm) for all parts. Maximum seated height is 0.028" (0.70mm) for Stackpole parts and 0.033" (0.84mm) for TE Connectivity parts. This minor height difference does not affect PCB layout compatibility.

Q: Which substitute should I select for improved measurement accuracy?

A: For applications requiring tighter tolerance control, select either CSRN2512FTR270 or RLP73K3AR27FTDF, both offering ±1% tolerance compared to the original ±5% specification.

Q: Are all substitutes suitable for automotive applications?

A: CSRN2512JTR270 and CSRN2512FTR270 carry explicit AEC-Q200 automotive qualification. RLP73K3AR27JTE and RLP73K3AR27FTDF are specified as current sense thick film resistors with identical operating temperature range and environmental ratings, suitable for automotive use.
