Parameter Comparison

Engineering Selection Recommendations

All three parts maintain Active product status and ROHS3 compliance, ensuring regulatory alignment for current applications. Selection between CF14JA510R, CFM12JT510R, and CFM14JT510R depends on circuit power dissipation requirements and board layout constraints.

CFM12JT510R provides increased power handling at 0.5W (1/2W) compared to the 0.25W (1/4W) rating of the main part, with slightly larger physical dimensions. This upgrade option is suitable for applications requiring higher thermal margin or increased power dissipation capability.

CFM14JT510R matches the 0.25W (1/4W) power rating of the main part but features reduced physical dimensions (0.067" Dia x 0.130" L versus 0.091" Dia x 0.236" L), offering space optimization for compact board designs. Both CFM series parts are supplied in Cut Tape (CT) packaging, whereas the CF14JA510R is supplied in Tape & Box (TB) format.

Frequently Asked Questions (FAQ)

Q: Can CFM12JT510R replace CF14JA510R in all applications?

A: CFM12JT510R is electrically equivalent in resistance, tolerance, and temperature characteristics. The primary difference is the increased power rating (0.5W versus 0.25W). This substitution is suitable for applications where the original 0.25W rating is adequate or where additional thermal margin is beneficial. Physical dimensions differ slightly due to the higher power rating.

Q: What is the difference between CF14JA510R and CFM14JT510R?

A: Both parts share identical electrical specifications: 510 Ohms ±5%, 0.25W power rating, and -55°C to 155°C operating range. The primary differences are packaging format (Tape & Box versus Cut Tape) and physical dimensions. CFM14JT510R is smaller (0.067" Dia x 0.130" L) compared to CF14JA510R (0.091" Dia x 0.236" L), making it suitable for space-constrained designs.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. CF14JA510R, CFM12JT510R, and CFM14JT510R are all ROHS3 compliant, meeting regulatory requirements for hazardous substance restrictions.

Q: Does packaging format affect electrical performance?

A: No. Packaging format (Tape & Box versus Cut Tape) affects supply and handling logistics only. Electrical performance and specifications remain identical regardless of packaging format.

Q: Can I use CFM14JT510R in place of CF14JA510R on existing PCBs?

A: Physical dimensions differ between these parts. CFM14JT510R is significantly smaller, which may affect PCB layout compatibility. Verify that the smaller footprint accommodates existing through-hole spacing and component placement before substitution.
