Key Parameters

Substitute Part Grouping Explanation

Substitute parts are classified into two categories based on allowed parameter variations:

Upgrade Substitutes (Higher Power Rating): Parts with identical resistance, tolerance, temperature coefficient, and package, but increased power rating (2W vs 1W). These provide enhanced thermal performance and are suitable for applications requiring higher current handling or thermal margin.

• CSRN2512FKR150 (Stackpole Electronics Inc)
• RLP73K3AR15FTDF (TE Connectivity Passive Product)

Similar Substitutes (Equivalent Specifications): Parts with matching resistance, tolerance, power rating, and package, but different packaging format or extended temperature range.

• RMCF2512FTR150 (Stackpole Electronics Inc)

All substitutes maintain the 2512 package footprint, ±1% tolerance, ±200ppm/°C temperature coefficient, and ROHS3 compliance required for direct replacement.

Parameter Comparison

Engineering Selection Recommendations

CSRN2512FKR150 and RLP73K3AR15FTDF are upgrade substitutes offering 2W power rating with extended operating temperature to 155°C. Both maintain ROHS3 compliance and are suitable for applications requiring higher thermal performance. CSRN2512FKR150 includes automotive AEC-Q200 qualification and current sense features. RLP73K3AR15FTDF provides current sense capability with TE Connectivity manufacturing support.

RMCF2512FTR150 is a similar substitute with equivalent 1W power rating and matching electrical specifications. It includes automotive AEC-Q200 qualification and extended operating temperature range to 155°C. This part is supplied in Cut Tape format rather than Tape & Reel.

All substitutes are active products with ROHS3 compliance and unlimited moisture sensitivity rating, ensuring regulatory and environmental compatibility with the original CRL2512-FW-R150ELF.

Frequently Asked Questions (FAQ)

Q: Can CSRN2512FKR150 or RLP73K3AR15FTDF replace CRL2512-FW-R150ELF in existing designs?

A: Yes. Both upgrade substitutes maintain identical resistance (150 mOhms), tolerance (±1%), package (2512), and temperature coefficient (±200ppm/°C). The increased 2W power rating provides additional thermal margin and is backward compatible with 1W applications.

Q: What is the difference between upgrade and similar substitutes?

A: Upgrade substitutes (CSRN2512FKR150, RLP73K3AR15FTDF) provide higher power rating (2W) and extended temperature range (-55°C ~ 155°C). Similar substitutes (RMCF2512FTR150) match the original 1W power rating and package footprint but differ in packaging format (Cut Tape vs Tape & Reel).

Q: Are all substitutes RoHS compliant?

A: Yes. All listed substitutes are ROHS3 compliant with unlimited moisture sensitivity rating (MSL 1), matching the original part's environmental and regulatory status.

Q: Does packaging format affect electrical performance?

A: No. Tape & Reel (TR) and Cut Tape (CT) formats contain identical components. Format selection depends on assembly process requirements and volume handling.

Q: What is the significance of automotive AEC-Q200 qualification?

A: AEC-Q200 qualification indicates the component meets automotive industry reliability and quality standards. CSRN2512FKR150 and RMCF2512FTR150 carry this certification, suitable for automotive and high-reliability applications.
