Engineering Selection Recommendations

Both the 93J330 and 93J330E are active production parts from Ohmite with identical electrical and mechanical specifications. Selection between these parts should be based on compliance requirements and supply availability:

93J330: Select this part for applications where RoHS non-compliant components are acceptable or required by specification. Current inventory: 800 pieces.

93J330E: Select this part for applications requiring ROHS3 compliance. This variant offers improved regulatory alignment for markets with strict environmental compliance mandates. Current inventory: 1015 pieces, providing greater availability.

Both parts are suitable for direct substitution in through-hole axial resistor applications requiring 330 Ohm, 3.25W power dissipation with ±5% tolerance and flame retardant safety features.

Frequently Asked Questions (FAQ)

Q: Can the 93J330E replace the 93J330 in existing designs? A: Yes. The 93J330E is a direct parametric equivalent with identical electrical characteristics (330 Ohms, ±5%, 3.25W), composition (wirewound), and physical dimensions (0.233" Dia x 0.579" L). Pin-to-pin and footprint compatibility is maintained for axial through-hole mounting.

Q: What is the primary difference between these two parts? A: The primary difference is RoHS compliance status. The 93J330E is ROHS3 compliant with MSL rating of 1 (Unlimited), while the 93J330 is RoHS non-compliant. Electrical and mechanical specifications are identical.

Q: Are there any package or dimensional differences? A: No. Both parts share identical axial package specifications with dimensions of 0.233" Dia x 0.579" L (5.90mm x 14.70mm). They are mechanically interchangeable in PCB layouts designed for axial resistors.

Q: Which part should be selected for new designs? A: For new designs, the 93J330E is recommended due to ROHS3 compliance, which aligns with current environmental regulations and provides broader market acceptance. Both parts maintain identical performance characteristics.

Q: Is there a difference in temperature performance? A: No. Both parts have identical temperature coefficient specifications of ±30ppm/°C, ensuring equivalent thermal stability across operating conditions.
