Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict equivalence across the following parameters: resistance value (1 Ohms), tolerance (±1%), package type (0805), composition (thick film), temperature coefficient (±200ppm/°C), operating temperature range (-55°C to 155°C), and moisture sensitivity level (MSL 1). Parts are grouped into three categories based on functional equivalence and compliance status:

Direct Equivalents maintain identical electrical specifications and automotive AEC-Q200 rating with 0.125W power rating.

Upgrade Equivalents provide enhanced features (moisture resistance) while maintaining core electrical parameters and automotive qualification.

MFR Recommended Equivalents include current sense variants with increased power rating (0.25W) suitable for applications requiring higher power dissipation in the same package footprint.

Parameter Comparison

Engineering Selection Recommendations

For AEC-Q200 Automotive Applications: CRCW08051R00FNEA (Vishay Dale) is the primary direct equivalent, offering identical electrical specifications with ROHS3 compliance and improved regulatory status compared to the original CRCW08051R00FNTA.

For Multi-Manufacturer Sourcing: RMCF0805FT1R00 (Stackpole Electronics Inc) and AC0805FR-071RL (YAGEO) provide functionally equivalent alternatives with AEC-Q200 rating and ROHS3 compliance. AC0805FR-071RL includes moisture-resistant features. Height variation (0.026" vs 0.020" vs 0.024") must be verified against PCB layout constraints.

For Higher Power Dissipation Requirements: CSR0805FK1R00 (Stackpole Electronics Inc) and RLP73K2A1R0FTDF (TE Connectivity) offer 0.25W power rating in the same 0805 package. These current sense variants are suitable for applications requiring increased thermal performance. Note that CSR0805FK1R00 lacks AEC-Q200 certification; RLP73K2A1R0FTDF is RoHS non-compliant.

For Regulatory Compliance: Parts with ROHS3 compliance status (CRCW08051R00FNEA, RMCF0805FT1R00, AC0805FR-071RL, CSR0805FK1R00, RC0805FR-071RL) are preferred for new designs subject to RoHS directives.

Frequently Asked Questions (FAQ)

Q: Can CRCW08051R00FNEA be used as a direct replacement for CRCW08051R00FNTA?

A: Yes. Both parts share identical electrical specifications (1 Ohm, ±1%, 0.125W), package type (0805), temperature coefficient (±200ppm/°C), operating range (-55°C to 155°C), and AEC-Q200 automotive rating. The primary difference is ROHS3 compliance status of the FNEA variant.

Q: What is the difference between 0.125W and 0.25W rated parts in this list?

A: Power rating indicates maximum continuous power dissipation. The 0.125W parts (CRCW08051R00FNTA, CRCW08051R00FNEA, RMCF0805FT1R00, AC0805FR-071RL, RC0805FR-071RL) are suitable for standard applications. The 0.25W parts (CSR0805FK1R00, RLP73K2A1R0FTDF) provide higher thermal capacity for current-sense applications or circuits with elevated power dissipation requirements. Selection depends on circuit design requirements, not interchangeability.

Q: Are there height differences between substitute parts?

A: Yes. The original CRCW08051R00FNTA has a maximum seated height of 0.020" (0.50mm). Substitute parts vary: CRCW08051R00FNEA matches at 0.020", while AC0805FR-071RL and RC0805FR-071RL are 0.024" (0.60mm), and RMCF0805FT1R00, CSR0805FK1R00, and RLP73K2A1R0FTDF are 0.026" (0.65mm). Verify PCB clearance and assembly constraints before substitution.

Q: Which substitute parts maintain AEC-Q200 automotive qualification?

A: CRCW08051R00FNEA, RMCF0805FT1R00, and AC0805FR-071RL retain AEC-Q200 rating. CSR0805FK1R00, RC0805FR-071RL, and RLP73K2A1R0FTDF do not carry AEC-Q200 certification. For automotive applications requiring AEC-Q200 compliance, use only the three qualified alternatives.

Q: What packaging formats are available?

A: Tape & Reel (TR) packaging is standard for most parts. AC0805FR-071RL and RC0805FR-071RL are supplied in Cut Tape (CT) & Digi-Reel format. Verify packaging compatibility with assembly equipment and procurement requirements.

Q: Is RoHS compliance required for my application?

A: ROHS3-compliant parts include CRCW08051R00FNEA, RMCF0805FT1R00, AC0805FR-071RL, CSR0805FK1R00, and RC0805FR-071RL. The original CRCW08051R00FNTA and RLP73K2A1R0FTDF are RoHS non-compliant. Select accordingly based on regulatory requirements for your end market.
