Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the CRCW08054R32FNTA are qualified based on the following criteria:

Electrical Parameters (Must Match):

• Resistance value: 4.32 Ohms
• Tolerance: ±1%
• Operating temperature range: -55°C ~ 155°C
• Package: 0805 (2012 Metric)
• Composition: Thick Film
• Number of terminations: 2

Mechanical Parameters (Must Match):

• Physical dimensions: 0.079" L x 0.049" W (2.00mm x 1.25mm)
• Package type: Surface mount chip resistor

Allowable Variations:

• Power rating: Substitute parts may have equal or higher power ratings (0.125W or greater)
• Temperature coefficient: Substitute parts may have equal or lower temperature coefficient values
• Height (seated): Minor variations acceptable within standard manufacturing tolerances
• Compliance status: Substitute parts may have improved RoHS or REACH compliance

Two substitute parts meet these criteria and are listed below.

Parameter Comparison

Engineering Selection Recommendations

ESR10EZPF4R32 (Rohm Semiconductor) qualifies as an upgrade substitute. This part maintains all electrical parameters while offering increased power rating (0.4W vs. 0.125W), improved temperature coefficient (±100ppm/°C vs. ±200ppm/°C), and enhanced compliance status (ROHS3 Compliant, REACH Unaffected). The part retains AEC-Q200 automotive qualification and pulse withstanding capability. Height variation (0.026" vs. 0.020") remains within standard PCB assembly tolerances for 0805 packages.

RC0805FR-074R32L (YAGEO) qualifies as a direct equivalent substitute. This part matches the electrical specifications and power rating of the original part. It provides improved compliance status (ROHS3 Compliant, REACH Unaffected) and moisture-resistant construction. Height variation (0.024" vs. 0.020") is minimal and acceptable for standard PCB assembly. This part does not carry explicit AEC-Q200 automotive qualification.

Both substitute parts are active products with confirmed inventory availability and maintain mechanical compatibility with the original 0805 package footprint.

Frequently Asked Questions (FAQ)

Q: Can ESR10EZPF4R32 be used as a direct replacement for CRCW08054R32FNTA?

A: Yes. ESR10EZPF4R32 meets all electrical and mechanical substitution criteria. The increased power rating (0.4W) and improved temperature coefficient (±100ppm/°C) provide enhanced performance margins. The 0.006" height difference (0.026" vs. 0.020") is within standard PCB assembly tolerances for 0805 packages and does not affect board-level compatibility.

Q: Can RC0805FR-074R32L be used as a direct replacement for CRCW08054R32FNTA?

A: Yes. RC0805FR-074R32L matches the electrical specifications and power rating of the original part. The 0.004" height difference (0.024" vs. 0.020") is within standard PCB assembly tolerances. Note that this part does not carry explicit AEC-Q200 automotive qualification, which may be a consideration for automotive applications requiring this specific certification.

Q: What are the key parameters that determine substitution compatibility?

A: Substitution compatibility is determined by: resistance value (4.32 Ohms), tolerance (±1%), operating temperature range (-55°C ~ 155°C), package type (0805 / 2012 Metric), composition (Thick Film), and physical dimensions (0.079" L x 0.049" W). Substitute parts may have equal or higher power ratings and equal or lower temperature coefficients.

Q: Are there compliance differences between these parts?

A: Yes. CRCW08054R32FNTA is RoHS non-compliant and REACH Affected. Both ESR10EZPF4R32 and RC0805FR-074R32L are ROHS3 Compliant and REACH Unaffected, providing improved regulatory compliance for new designs.

Q: Do all three parts have the same moisture sensitivity level?

A: Yes. All three parts are rated MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage and handling.

Q: What is the difference in temperature coefficient between these parts?

A: CRCW08054R32FNTA and RC0805FR-074R32L both have ±200ppm/°C temperature coefficient. ESR10EZPF4R32 has an improved ±100ppm/°C temperature coefficient, providing better resistance stability across temperature variations.
