Substitute Part Grouping Explanation

Substitution for the CRCW08054R53FNTA is determined by strict equivalence across the following critical parameters:

• Resistance value: 4.53 Ohms
• Tolerance: ±1%
• Power rating: 0.125W (1/8W)
• Package: 0805 (2012 Metric)
• Composition: Thick Film
• Temperature coefficient: ±200ppm/°C
• Operating temperature range: -55°C to 155°C
• Automotive qualification: AEC-Q200
• Termination count: 2
• Moisture sensitivity: MSL 1

The RMCF0805FT4R53 manufactured by Stackpole Electronics Inc meets all these criteria and is classified as a direct substitute.

Parameter Comparison

Engineering Selection Recommendations

Both the CRCW08054R53FNTA and RMCF0805FT4R53 are active production parts with identical electrical specifications and automotive AEC-Q200 qualification. Selection between these parts should be based on the following factors:

The RMCF0805FT4R53 offers ROHS3 compliance, which may be required for applications subject to RoHS regulations. The CRCW08054R53FNTA is RoHS non-compliant and should be selected only when RoHS exemptions apply or are not required.

Physical height differs between the two parts: the CRCW08054R53FNTA has a maximum seated height of 0.020" (0.50mm), while the RMCF0805FT4R53 has a maximum seated height of 0.026" (0.65mm). This difference may impact PCB layout and clearance considerations in space-constrained applications.

Both parts are MSL 1 rated and suitable for unlimited shelf life storage without moisture bake-out requirements.

Frequently Asked Questions (FAQ)

Q: Can RMCF0805FT4R53 be used as a direct replacement for CRCW08054R53FNTA?

A: Yes. Both parts share identical electrical specifications: 4.53 Ohms ±1%, 0.125W power rating, ±200ppm/°C temperature coefficient, and -55°C to 155°C operating range. Both are AEC-Q200 qualified thick film resistors in 0805 package with 2 terminations. Physical height differs by 0.006" (0.15mm), which may require PCB layout verification in space-constrained designs.

Q: What is the primary difference between these two parts?

A: The RMCF0805FT4R53 is ROHS3 compliant, while the CRCW08054R53FNTA is RoHS non-compliant. The Stackpole part also has a slightly greater maximum seated height (0.026" vs 0.020"). Electrical performance and automotive qualification are identical.

Q: Are both parts suitable for automotive applications?

A: Yes. Both the CRCW08054R53FNTA and RMCF0805FT4R53 carry AEC-Q200 automotive qualification and operate across -55°C to 155°C, meeting automotive temperature and reliability requirements.

Q: Does the height difference affect PCB assembly?

A: The 0.006" (0.15mm) height difference between parts may be relevant in applications with tight vertical clearance constraints. Verify PCB layout and component stacking requirements before substitution in space-critical designs.

Q: What is MSL 1 rating?

A: MSL 1 (Moisture Sensitivity Level 1) indicates unlimited shelf life. These parts do not require moisture bake-out prior to soldering and can be stored indefinitely under normal conditions without special handling.
