Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict equivalence across the following parameters: resistance value (300 kOhms), tolerance (±1%), power rating (0.125W), package type (0805 / 2012 Metric), composition (thick film), temperature coefficient (±100ppm/°C), operating temperature range (-55°C to 155°C), and termination count (2). All identified substitute parts meet these core electrical and mechanical requirements. Variations in height-seated maximum dimension and RoHS compliance status do not affect functional substitutability within the specified parameter set.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts are functionally equivalent to the CRCW0805300KFKTC based on matching electrical specifications and package dimensions. The primary distinction is RoHS compliance status: the original part is RoHS non-compliant, while all substitute options (CRCW0805300KFKEA, ERJ-6ENF3003V, RMCF0805FG300K, RMCF0805FT300K, and CR0805-FX-3003ELF) are ROHS3 compliant. For applications requiring RoHS compliance, any of the substitute parts are suitable direct replacements. The CRCW0805300KFKEA maintains identical height-seated dimensions to the original part and is from the same manufacturer. The Stackpole Electronics options (RMCF0805FG300K and RMCF0805FT300K) offer higher inventory availability. The Panasonic ERJ-6ENF3003V provides the largest inventory stock. The Bourns CR0805-FX-3003ELF is designated as manufacturer-recommended and features moisture-resistant construction.

Frequently Asked Questions (FAQ)

Q: Can I substitute CRCW0805300KFKTC with any of the listed parts without circuit redesign?

A: Yes. All listed substitute parts match the core electrical parameters (300 kOhms ±1%, 0.125W, ±100ppm/°C, -55°C to 155°C) and package type (0805 / 2012 Metric). Physical height variations (0.50mm to 0.70mm) are within standard PCB assembly tolerances and do not require circuit redesign.

Q: What is the difference between CRCW0805300KFKTC and CRCW0805300KFKEA?

A: Both parts are manufactured by Vishay Dale with identical electrical specifications and physical dimensions. The primary difference is RoHS compliance: CRCW0805300KFKTC is RoHS non-compliant, while CRCW0805300KFKEA is ROHS3 compliant. CRCW0805300KFKEA has significantly higher inventory availability (29735 pcs vs. 944 pcs).

Q: Are automotive AEC-Q200 rated substitutes available?

A: The original CRCW0805300KFKTC is explicitly rated for automotive AEC-Q200 applications. The Panasonic ERJ-6ENF3003V and Stackpole RMCF series parts are also AEC-Q200 rated. The Bourns CR0805-FX-3003ELF does not list explicit AEC-Q200 rating but meets all electrical and thermal specifications for automotive temperature ranges.

Q: What is the impact of height-seated dimension differences?

A: Height-seated dimensions range from 0.50mm (CRCW0805300KFKTC and CRCW0805300KFKEA) to 0.70mm (ERJ-6ENF3003V). These variations are within standard 0805 package tolerances and do not affect PCB assembly, solder joint reliability, or circuit performance.

Q: Which substitute part has the best inventory availability?

A: The Panasonic ERJ-6ENF3003V offers the highest inventory stock at 128779 pcs. The Stackpole RMCF0805FT300K provides 73649 pcs, and the Bourns CR0805-FX-3003ELF provides 39387 pcs.

Q: Can I use CR0805-FX-3003ELF as a direct replacement?

A: Yes. The CR0805-FX-3003ELF meets all electrical specifications and is designated as a manufacturer-recommended equivalent. It features moisture-resistant construction and ROHS3 compliance. The only distinction is the absence of explicit AEC-Q200 automotive rating, though thermal and electrical performance covers automotive temperature ranges.
