Parameter Comparison

Engineering Selection Recommendations

CRCW080518K0FHEAP (Vishay Dale) is the closest electrical and mechanical equivalent to the RE0805FRE0718KL. It maintains identical resistance, tolerance, and power rating specifications. The Vishay Dale part includes AEC-Q200 automotive qualification and features a lower seated height (0.020" vs 0.024"), making it suitable for space-constrained applications. This substitute is appropriate for general-purpose and automotive-grade applications.

ERJ-PB6B1802V (Panasonic) offers enhanced tolerance performance at ±0.1% and increased power rating of 0.25W. This part includes AEC-Q200 automotive qualification and pulse withstanding capability. The higher seated height (0.028") requires PCB layout verification. This substitute is recommended for applications requiring tighter tolerance control and higher power dissipation margins.

ERJ-PB6D1802V (Panasonic) provides intermediate tolerance at ±0.5% with the same 0.25W power rating and AEC-Q200 automotive qualification as the ERJ-PB6B1802V. This part offers a balance between tolerance performance and cost considerations. The higher seated height (0.028") requires PCB layout verification. This substitute is suitable for automotive and industrial applications with moderate tolerance requirements.

All substitute parts maintain full compliance with RoHS3 and REACH regulations, with MSL rating of 1 (Unlimited), ensuring compatibility with standard manufacturing and storage conditions.

Frequently Asked Questions (FAQ)

Q: Can CRCW080518K0FHEAP be used as a direct replacement for RE0805FRE0718KL?

A: Yes. Both parts share identical electrical specifications (18 kOhms ±1%, 0.125W) and package dimensions (0805 2012 Metric). The CRCW080518K0FHEAP features a lower seated height (0.020" vs 0.024"), which is advantageous for compact PCB designs. No circuit modifications are required.

Q: What is the difference between the two Panasonic substitutes?

A: ERJ-PB6B1802V and ERJ-PB6D1802V differ in tolerance specification. ERJ-PB6B1802V provides ±0.1% tolerance, while ERJ-PB6D1802V provides ±0.5% tolerance. Both offer 0.25W power rating and AEC-Q200 automotive qualification. Selection depends on circuit tolerance requirements and cost considerations.

Q: Are the Panasonic parts suitable for non-automotive applications?

A: Yes. AEC-Q200 qualification indicates automotive-grade reliability and is not restrictive for general-purpose applications. The Panasonic parts are fully compatible with standard industrial and consumer electronics applications.

Q: What is the impact of different seated heights on PCB design?

A: Seated height variations (0.020" to 0.028") may affect PCB clearance and solder joint geometry. For applications with tight vertical spacing constraints, the CRCW080518K0FHEAP (0.020" height) is preferred. For standard applications, all parts are mechanically compatible with 0805 footprints.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed parts, including the original RE0805FRE0718KL and all substitutes, are ROHS3 Compliant with MSL rating of 1 (Unlimited), ensuring compatibility with standard manufacturing processes and environmental regulations.

Q: Can tolerance differences affect circuit performance?

A: Yes, in precision applications. The original RE0805FRE0718KL and CRCW080518K0FHEAP both provide ±1% tolerance. The Panasonic ERJ-PB6B1802V (±0.1%) offers significantly tighter tolerance for applications requiring high accuracy. ERJ-PB6D1802V (±0.5%) provides intermediate tolerance performance.
