Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RCL1218470RFKEK is determined by the following critical parameters:

Resistance value and tolerance must match exactly at 470 Ohms ±1%. Power rating must be equivalent at 1W. Package designation must be Wide 1812 (1218) to ensure mechanical and electrical compatibility with existing PCB layouts. Composition type (thick film) and temperature coefficient (±100ppm/°C) must remain consistent. Operating temperature range must span -55°C to 155°C minimum. RoHS3 compliance and MSL 1 rating are required for environmental and handling compatibility.

The RC1218FK-07470RL from YAGEO meets all substitution criteria through matching electrical specifications, identical package format, equivalent thermal performance, and equivalent compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

Both the RCL1218470RFKEK and RC1218FK-07470RL maintain active product status with current manufacturing support. Selection between these components should be based on availability, lead time, and supply chain requirements. The RC1218FK-07470RL from YAGEO offers 8041 units in current inventory compared to 4400 units for the Vishay Dale part. Both components satisfy ROHS3 compliance and AEC-Q200 automotive qualification requirements. Mechanical dimensions show minor variations within acceptable tolerances: the YAGEO part measures 0.122" L x 0.181" W (3.10mm x 4.60mm) with 0.026" maximum seated height, while the Vishay Dale part measures 0.126" L x 0.181" W (3.20mm x 4.60mm) with 0.024" maximum seated height. These dimensional differences remain within standard PCB layout tolerances for Wide 1812 package specifications.

Frequently Asked Questions (FAQ)

Q: Can RC1218FK-07470RL replace RCL1218470RFKEK in automotive applications?

A: Yes. Both components meet AEC-Q200 automotive qualification standards and share identical electrical specifications (470 Ohms ±1%, 1W, ±100ppm/°C). The Wide 1812 package format is mechanically compatible with existing PCB designs.

Q: Are there dimensional compatibility concerns between these parts?

A: Minor dimensional variations exist within acceptable tolerances. The YAGEO RC1218FK-07470RL is 0.004" shorter in length (3.10mm vs 3.20mm) and 0.002" taller in seated height (0.65mm vs 0.60mm). These differences fall within standard Wide 1812 package specifications and do not affect PCB assembly or electrical performance.

Q: Do both parts require identical handling and storage conditions?

A: Yes. Both components carry MSL 1 (Unlimited) moisture sensitivity ratings, indicating no special moisture control requirements during storage or handling. Standard ESD precautions apply to both parts.

Q: What compliance certifications apply to both substitute parts?

A: Both the RCL1218470RFKEK and RC1218FK-07470RL are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with HTSUS code 8533.21.0030.

Q: Are there performance differences in temperature coefficient or operating range?

A: No. Both components specify identical temperature coefficient (±100ppm/°C) and operating temperature range (-55°C to 155°C), ensuring equivalent thermal performance across all operating conditions.
