Parameter Comparison

Engineering Selection Recommendations

RC1206FR-0712L (YAGEO): Direct substitute with Active product status. Identical electrical and mechanical specifications. Tape & Reel packaging suitable for automated assembly. Recommended for new designs requiring standard industrial-grade thick film resistors.

CRCW120612R7FKEA (Vishay Dale): Direct substitute with Active product status and automotive AEC-Q200 qualification. Suitable for applications requiring automotive-grade reliability. Tape & Reel packaging. Recommended for automotive and high-reliability applications.

ERJ-8ENF12R7V (Panasonic Electronic Components): Electrical and mechanical equivalence confirmed. Product status is "Not For New Designs," indicating this part is in mature/legacy phase. Automotive AEC-Q200 qualified. Tape & Reel packaging. Suitable only for legacy system maintenance or replacement applications where existing designs already specify this component.

Frequently Asked Questions (FAQ)

Q: Can RC1206FR-0712R7L replace RC3216F12R7CS in all applications?

A: Yes. Both components share identical electrical specifications (12.7 Ohms ±1%, 0.25W), mechanical package (1206), composition (thick film), temperature characteristics (±100ppm/°C, -55°C ~ 155°C), and compliance ratings (ROHS3, MSL 1). The primary difference is packaging format: RC3216F12R7CS is supplied in bulk, while RC1206FR-0712R7L is supplied in Tape & Reel format.

Q: What is the difference between CRCW120612R7FKEA and ERJ-8ENF12R7V?

A: Both parts are electrically and mechanically equivalent to the main part. The key difference is product status: CRCW120612R7FKEA is Active (recommended for new designs), while ERJ-8ENF12R7V is "Not For New Designs" (legacy status). Both carry automotive AEC-Q200 qualification. For new designs, CRCW120612R7FKEA is the preferred choice.

Q: Are there dimensional differences between these substitutes?

A: Minor dimensional variations exist within acceptable tolerances. RC3216F12R7CS and CRCW120612R7FKEA share identical length (0.126"), while RC1206FR-0712R7L is slightly shorter (0.122"). Height variations range from 0.024" to 0.028" (0.60mm to 0.70mm). All dimensions remain within 1206 package specification and are compatible with standard PCB footprints.

Q: Which substitute should be selected for automotive applications?

A: CRCW120612R7FKEA (Vishay Dale) is the recommended choice for automotive applications due to Active product status and AEC-Q200 qualification. ERJ-8ENF12R7V also carries AEC-Q200 qualification but is not recommended for new designs.

Q: What is the significance of Tape & Reel packaging?

A: Tape & Reel (TR) packaging is standard for automated pick-and-place assembly processes. RC1206FR-0712R7L, CRCW120612R7FKEA, and ERJ-8ENF12R7V are all supplied in TR format, making them suitable for high-volume manufacturing. The original RC3216F12R7CS bulk packaging may require manual handling or reel conversion for automated assembly.
