AF0201JR-07180RL Equivalent & Substitute Parts

Part Overview

The AF0201JR-07180RL is a 180 Ohm ±5% thick film chip resistor in 0201 package format rated at 0.05W (1/20W). Manufactured by YAGEO under the AF series, this component is designed for automotive applications with AEC-Q200 qualification and anti-sulfur properties. The part is currently in active production status with 1075 units in stock.

Equivalent and substitute parts are necessary when the primary part becomes unavailable, when design requirements shift toward higher tolerance specifications, or when alternative manufacturers' components offer improved availability or performance characteristics within the same electrical and mechanical parameters.

Key Parameters

Parameter	Value
Resistance	180 Ohms
Tolerance	±5%
Power Rating	0.05W (1/20W)
Package	0201 (0603 Metric)
Composition	Thick Film
Temperature Coefficient	±200ppm/°C
Operating Temperature Range	-55°C to 125°C
RoHS Status	ROHS3 Compliant
Moisture Sensitivity Level	1 (Unlimited)

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict adherence to the following parameters:

Resistance Value: Must be 180 Ohms
Package Format: Must be 0201 (0603 Metric)
Power Rating: Must be 0.05W (1/20W)
Composition: Must be Thick Film
Temperature Coefficient: Must be ±200ppm/°C
Compliance: Must maintain ROHS3 compliance and MSL 1 rating

Tolerance variations (±5% vs ±1%) are permitted as tighter tolerances represent functional equivalence with enhanced precision. Operating temperature range extensions are acceptable substitutions. Automotive AEC-Q200 rating and moisture-resistant features are beneficial but not mandatory for electrical equivalence.

Engineering Selection Recommendations

Primary Substitutes (Active Status, Equivalent Specifications)

AC0201FR-07180RL and CRCW0201180RFNED are direct functional equivalents with tighter ±1% tolerance and extended operating temperature to 155°C. Both maintain active production status and ROHS3 compliance. AC0201FR-07180RL offers YAGEO continuity with automotive AEC-Q200 qualification. CRCW0201180RFNED provides Vishay Dale sourcing with equivalent electrical performance.

Secondary Substitutes (Tolerance-Matched, Active Status)

RC0201JR-07180RL and CRCW0201180RJNED match the ±5% tolerance specification of the primary part. RC0201JR-07180RL maintains YAGEO sourcing with moisture-resistant features. CRCW0201180RJNED extends operating temperature to 155°C while preserving tolerance and power rating.

Alternative Substitutes (Active Status, Panasonic Sourcing)

ERJ-1GNF1800C and ERJ-1GNJ181C provide Panasonic Electronic Components sourcing. ERJ-1GNF1800C offers ±1% tolerance with active production. ERJ-1GNJ181C matches ±5% tolerance specification with active status.

Obsolete Alternative (Not Recommended for New Designs)

ERJ-1GEF1800C is functionally equivalent but carries obsolete product status. Use only when existing inventory must be maintained or when design revision is not feasible.

Frequently Asked Questions (FAQ)

Q: Can I substitute a ±1% tolerance part for the ±5% AF0201JR-07180RL?

A: Yes. Parts with ±1% tolerance (AC0201FR-07180RL, CRCW0201180RFNED, ERJ-1GNF1800C) are direct functional substitutes. Tighter tolerance represents enhanced precision and is electrically compatible with circuits designed for ±5% components.

Q: Are there differences between YAGEO, Vishay Dale, and Panasonic 0201 resistors?

A: All listed parts share identical electrical specifications (180Ω, 0.05W, ±200ppm/°C, 0201 package, ROHS3 compliance). Differences exist only in manufacturer-specific features: YAGEO AF series includes anti-sulfur and AEC-Q200 automotive qualification; Vishay Dale CRCW series provides extended temperature range; Panasonic ERJ series offers alternative sourcing. Selection depends on supply chain requirements and application-specific certifications.

Q: What is the impact of extended operating temperature range (-55°C to 155°C vs -55°C to 125°C)?

A: Extended range provides additional thermal margin but does not affect electrical performance within the original -55°C to 125°C specification. Parts with extended range (AC0201FR-07180RL, CRCW0201180RFNED, CRCW0201180RJNED) are suitable for applications requiring higher temperature operation.

Q: Is the 0201 package interchangeable across all listed parts?

A: Yes. All parts use identical 0201 (0603 Metric) package format with matching dimensions (0.024" L x 0.012" W, 0.60mm x 0.30mm) and height (0.010" maximum seated). PCB footprints and pick-and-place equipment settings are fully compatible.

Q: Can I use ERJ-1GEF1800C if it is obsolete?

A: ERJ-1GEF1800C is electrically equivalent but carries obsolete status. Use only when maintaining existing inventory or when design revision is not feasible. For new designs, select from active-status alternatives: ERJ-1GNF1800C (±1%) or ERJ-1GNJ181C (±5%).

Q: What does MSL 1 (Unlimited) moisture sensitivity mean?

A: MSL 1 indicates the component requires no special moisture control during storage, handling, or assembly. All listed parts carry MSL 1 rating, eliminating moisture-related compatibility concerns.
