AF0805JR-072RL Equivalent & Substitute Parts

Part Overview

The AF0805JR-072RL is a 2 Ohm ±5% 0.125W thick film chip resistor in 0805 (2012 Metric) package manufactured by YAGEO. This component is rated for automotive applications under AEC-Q200 and features anti-sulfur construction. The part is active in production with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1).

Substitute parts are identified when electrical parameters (resistance, tolerance, power rating) and mechanical specifications (package, dimensions, terminations) remain compatible with the original design requirements.

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following criteria:

Primary Compatibility Requirements:

Resistance value: 2 Ohms (exact match required)

Terminations: 2 (exact match required)
Operating temperature range: -55°C ~ 155°C (minimum requirement)
RoHS compliance: ROHS3 or equivalent

Secondary Compatibility Parameters:

Tolerance: ±5% or tighter (±1% is acceptable as superior specification)
Power rating: 0.125W minimum (higher ratings such as 0.4W are acceptable)
Temperature coefficient: ±200ppm/°C or better
Composition: Thick film (standard for this category)

Grouping Logic:

Group A: Direct equivalents with ±5% tolerance, 0.125W power, automotive AEC-Q200 rated
Group B: Enhanced tolerance variants (±1%) with same power and automotive rating
Group C: Higher power variants (0.4W) with automotive rating for applications requiring additional thermal margin

Engineering Selection Recommendations

Direct Substitution (Identical Electrical & Mechanical Specifications):

AC0805JR-072RL: YAGEO equivalent with identical specifications. Automotive AEC-Q200 rated. Tape & Reel packaging. Suitable for direct replacement in production designs.
CRCW08052R00JNEA: Vishay Dale equivalent with identical electrical specifications. Automotive AEC-Q200 rated. Tape & Reel packaging. Height 0.50mm (0.10mm lower than original). Suitable for direct replacement.

Enhanced Tolerance Substitution (±1% vs ±5%):

AC0805FR-072RL: YAGEO with tighter ±1% tolerance. Automotive AEC-Q200 rated. Identical power and package. Suitable where improved tolerance is required.
CRCW08052R00FNEA: Vishay Dale with ±1% tolerance. Automotive AEC-Q200 rated. Height 0.50mm. Suitable where improved tolerance is required.
RMCF0805FT2R00: Stackpole with ±1% tolerance. Automotive AEC-Q200 rated. Height 0.65mm. Suitable where improved tolerance is required.

Higher Power Substitution (0.4W vs 0.125W):

ESR10EZPJ2R0: Rohm Semiconductor with 0.4W power rating. Automotive AEC-Q200 rated. ±5% tolerance. Height 0.65mm. Suitable for applications requiring additional thermal margin or pulse withstanding capability.
ESR10EZPF2R00: Rohm Semiconductor with 0.4W power rating and ±1% tolerance. Automotive AEC-Q200 rated. Temperature coefficient ±100ppm/°C (superior). Height 0.65mm. Suitable for demanding applications requiring both higher power and tighter tolerance.

Non-Automotive Substitution (Standard Industrial):

Frequently Asked Questions (FAQ)

Q: Can I substitute AF0805JR-072RL with a part having ±1% tolerance? A: Yes. Parts with ±1% tolerance (AC0805FR-072RL, CRCW08052R00FNEA, RMCF0805FT2R00) are direct substitutes. Tighter tolerance is a superior specification and does not compromise compatibility.

Q: Are Rohm ESR10EZPJ2R0 and ESR10EZPF2R00 suitable replacements? A: Yes, with design consideration. Both have identical 2 Ohm resistance and ±5% or ±1% tolerance. The 0.4W power rating (vs 0.125W original) provides additional thermal margin. Height is 0.65mm (vs 0.60mm original). Verify PCB layout clearance before substitution.

Q: What is the difference between Tape & Reel and Cut Tape & Digi-Reel packaging? A: Both are surface mount packaging formats. Tape & Reel is continuous reel format suitable for high-volume automated assembly. Cut Tape & Digi-Reel is pre-cut tape format suitable for lower volumes or mixed component picking. Electrical and mechanical specifications are identical; packaging choice depends on assembly process requirements.

Q: Can I use RC0805JR-072RL or RC0805FR-072RL as substitutes? A: Only if automotive AEC-Q200 qualification is not required. These YAGEO RC series parts lack AEC-Q200 rating. For automotive applications, use only AEC-Q200 rated alternatives (AC series, CRCW series, ESR series, or RMCF series).

Q: What is the significance of the height difference (0.50mm vs 0.60mm vs 0.65mm)? A: Height variation is within standard 0805 package tolerance. Verify PCB design clearance for components with 0.65mm height (Rohm ESR and Stackpole RMCF series). Vishay CRCW series at 0.50mm provides additional clearance margin.

Q: Are all listed substitutes ROHS3 compliant? A: Yes. All listed substitute parts are ROHS3 compliant with REACH Unaffected status and MSL 1 (Unlimited) moisture sensitivity rating, matching the original AF0805JR-072RL specifications.
