AC2010FK-07205RL Equivalent & Substitute Parts

Part Overview

The AC2010FK-07205RL is a 205 Ohms ±1% thick film chip resistor rated at 0.75W (3/4W) in the 2010 (5025 Metric) package. Manufactured by YAGEO under the AC series, this component is designed for automotive applications and meets AEC-Q200 qualification standards. The part is moisture resistant and currently in active production status with 815 pieces available in stock.

Identifying equivalent and substitute parts is necessary when the primary component becomes unavailable, when supply chain optimization is required, or when design flexibility allows for alternative qualified sources while maintaining electrical and mechanical compatibility.

Substitute Part Grouping Explanation

Substitution eligibility for the AC2010FK-07205RL is determined by strict equivalence across the following critical parameters:

• Resistance value: 205 Ohms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 0.75W / 3/4W (exact match required)
• Package: 2010 (5025 Metric) (exact match required)
• Composition: Thick Film (exact match required)
• Temperature coefficient: ±100ppm/°C (exact match required)
• Operating temperature range: -55°C ~ 155°C (exact match required)
• Automotive qualification: AEC-Q200 (exact match required)
• Moisture sensitivity: MSL 1 (exact match required)
• RoHS compliance: ROHS3 Compliant (exact match required)

The CRCW2010205RFKEF from Vishay Dale meets all substitution criteria and is classified as a direct equivalent.

Parameter Comparison

Engineering Selection Recommendations

Both the AC2010FK-07205RL and CRCW2010205RFKEF are active production components with full AEC-Q200 automotive qualification and ROHS3 compliance. Selection between these parts may be based on:

• Availability and lead time from respective suppliers
• Inventory levels (AC2010FK-07205RL: 815 pcs; CRCW2010205RFKEF: 5006 pcs)
• Procurement cost and volume pricing
• Existing supply chain relationships with YAGEO or Vishay Dale

The maximum seated height difference of 0.002" (0.05mm) between the two parts is negligible for standard PCB assembly processes and does not affect electrical performance or mechanical fit in standard 2010 package footprints.

Frequently Asked Questions (FAQ)

Q: Can CRCW2010205RFKEF be used as a direct replacement for AC2010FK-07205RL?
