All substitute parts are Active status products with full compliance documentation and unlimited availability through standard distribution channels.

Parameter Comparison

Engineering Selection Recommendations

Direct Substitution (1/8W Category):

RMCF0805FT47R5 (Stackpole Electronics Inc) is suitable for direct substitution with AEC-Q200 automotive qualification. This part maintains identical electrical specifications and physical footprint with 310,230 units in stock inventory.

RC0805FR-0747R5L (YAGEO) provides direct substitution capability with moisture-resistant features matching the original specification. This part offers the highest inventory availability at 144,888 units.

CRCW080547R5FKEA (Vishay Dale) is qualified for direct substitution with AEC-Q200 automotive rating and 19,535 units available. The seated height of 0.020" (0.50mm) is lower than the original part, providing additional clearance margin in space-constrained layouts.

ERJ-6ENF47R5V (Panasonic Electronic Components) supports direct substitution with AEC-Q200 automotive qualification and the highest inventory level at 116,866 units. The seated height of 0.028" (0.70mm) is marginally higher than the original specification.

Enhanced Power Rating Option:

CRCW080547R5FKEAHP (Vishay Dale) provides substitution with increased 0.5W (1/2W) power rating and pulse withstanding capability. This part is suitable for applications requiring higher thermal margin or pulse energy handling while maintaining all other core electrical and mechanical parameters. AEC-Q200 automotive qualification is included. Inventory availability is 18,760 units.

All substitute parts maintain ROHS3 compliance, unlimited moisture sensitivity level (MSL 1), and Active product status. Selection between direct equivalents depends on application-specific requirements for automotive qualification, inventory availability, and physical height constraints.

Frequently Asked Questions (FAQ)

Q: Can CRCW080547R5FKEAHP (1/2W) be used in place of RCS2012F47R5CS (1/8W)?

A: Yes. The CRCW080547R5FKEAHP maintains all core electrical parameters (47.5 Ohms, ±1% tolerance, ±100ppm/°C temperature coefficient, -55°C to 155°C operating range) and physical package (0805 / 2012 Metric). The increased power rating of 0.5W provides additional thermal margin and pulse withstanding capability. No electrical or mechanical incompatibility exists. The part is suitable for any application where the original 1/8W part was specified.

Q: Are all substitute parts compatible with the same PCB footprint?

A: Yes. All substitute parts use the 0805 (2012 Metric) package with identical land pattern dimensions of 0.079" L x 0.049" W (2.00mm x 1.25mm). Seated height variations range from 0.020" (0.50mm) to 0.028" (0.70mm), which fall within standard PCB assembly tolerances and do not affect footprint compatibility. No PCB redesign is required for substitution.

Q: Which substitute parts carry automotive qualification?

A: RMCF0805FT47R5 (Stackpole), CRCW080547R5FKEA (Vishay Dale), CRCW080547R5FKEAHP (Vishay Dale), and ERJ-6ENF47R5V (Panasonic) all carry AEC-Q200 automotive qualification. RC0805FR-0747R5L (YAGEO) does not specify automotive qualification. Selection of AEC-Q200 qualified parts is required for automotive applications.

Q: What is the difference between the two Vishay Dale parts (CRCW080547R5FKEA and CRCW080547R5FKEAHP)?

A: Both parts are manufactured by Vishay Dale with identical resistance (47.5 Ohms), tolerance (±1%), package (0805), and operating temperature range (-55°C to 155°C). The primary difference is power rating: CRCW080547R5FKEA is rated at 0.125W (1/8W), while CRCW080547R5FKEAHP is rated at 0.5W (1/2W) with pulse withstanding capability. Both carry AEC-Q200 automotive qualification.

Q: Which substitute part has the highest inventory availability?

A: RMCF0805FT47R5 (Stackpole Electronics Inc) has the highest inventory at 310,230 units in stock. RC0805FR-0747R5L (YAGEO) is second with 144,888 units, and ERJ-6ENF47R5V (Panasonic) is third with 116,866 units.

Q: Do all parts meet RoHS and REACH compliance requirements?

A: Yes. All substitute parts are ROHS3 compliant and REACH unaffected, matching the compliance status of the original RCS2012F47R5CS part.

Q: Can these parts be used interchangeably in high-reliability applications?

A: All substitute parts maintain identical electrical specifications, operating temperature range, and moisture sensitivity level (MSL 1 / Unlimited). Parts with AEC-Q200 qualification (RMCF0805FT47R5, CRCW080547R5FKEA, CRCW080547R5FKEAHP, ERJ-6ENF47R5V) are suitable for automotive and high-reliability applications. RC0805FR-0747R5L lacks specified automotive qualification and should be evaluated against application-specific reliability requirements.
