Parameter Comparison

Engineering Selection Recommendations

All three parts are actively produced and ROHS3 compliant. Selection between the RGC1206FTD2M21 and its substitutes depends on availability and application-specific requirements:

CRCW12062M21FKEA (Vishay Dale) carries AEC-Q200 automotive qualification. This part is suitable for applications requiring automotive-grade reliability standards.

RC1206FR-072M21L (YAGEO) features moisture-resistant construction. This part is suitable for applications with elevated moisture exposure requirements.

RGC1206FTD2M21 (Stackpole Electronics Inc) remains the primary specification. Use this part when no specific automotive or moisture-resistant requirements exist.

Frequently Asked Questions (FAQ)

Q: Can CRCW12062M21FKEA replace RGC1206FTD2M21 in non-automotive applications?

A: Yes. The CRCW12062M21FKEA meets all electrical and mechanical parameters of the RGC1206FTD2M21. AEC-Q200 qualification is an additional feature that does not restrict use in general-purpose applications.

Q: What is the difference between the moisture-resistant RC1206FR-072M21L and the standard RGC1206FTD2M21?

A: Both parts have identical Moisture Sensitivity Level 1 (Unlimited) ratings. The moisture-resistant feature of the RC1206FR-072M21L provides additional protection in high-humidity environments but does not affect electrical performance or compatibility.

Q: Are dimensional differences between substitutes significant?

A: Dimensional variations exist within tolerance. RGC1206FTD2M21 measures 0.122" L x 0.061" W (3.10mm x 1.55mm). CRCW12062M21FKEA measures 0.126" L x 0.063" W (3.20mm x 1.60mm). RC1206FR-072M21L measures 0.122" L x 0.063" W (3.10mm x 1.60mm). All dimensions fall within 1206 package specifications and are compatible with standard PCB footprints.

Q: Can these parts be used interchangeably on the same PCB?

A: Yes. All parts share identical 1206 (3216 Metric) package designation, two-terminal configuration, and electrical specifications. PCB footprints designed for RGC1206FTD2M21 accommodate all listed substitutes.

Q: Which substitute has the highest inventory availability?

A: RC1206FR-072M21L (YAGEO) shows 113,808 pieces in stock, compared to CRCW12062M21FKEA (Vishay Dale) with 14,139 pieces and RGC1206FTD2M21 (Stackpole) with 690 pieces.
