Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 95J33R are qualified based on matching the following critical parameters: resistance value (33 Ohms), tolerance (±5%), power rating (5W), composition (wirewound), package type (axial), temperature coefficient (±30ppm/°C), and safety features (flame retardant coating). Physical dimensions may vary within acceptable tolerances for through-hole axial components. All substitute parts maintain identical electrical performance specifications and are compatible with standard PCB layouts designed for axial resistor footprints.

Parameter Comparison

Engineering Selection Recommendations

The 95J33RE serves as the parametric equivalent substitute, maintaining identical dimensions and series classification while offering ROHS3 compliance. This part is suitable for applications requiring regulatory compliance with modern environmental standards. The 25J33R is classified as a manufacturer-recommended substitute with equivalent electrical specifications but operates under the Series 20 designation with slightly larger physical dimensions (0.276" diameter, 1.016" length). Both substitute parts maintain Active product status and are suitable for direct replacement in applications where the primary electrical and thermal requirements are met. Selection between substitutes should be based on compliance requirements and available inventory.

Frequently Asked Questions (FAQ)

Q: Can the 25J33R be used as a direct replacement for the 95J33R? A: Yes. Both parts share identical electrical specifications: 33 Ohms, ±5% tolerance, 5W power rating, wirewound composition, and axial package type. The 25J33R has slightly larger physical dimensions (0.276" diameter versus 0.264" diameter), which must be verified for PCB layout compatibility.

Q: What is the difference between the 95J33R and 95J33RE? A: The 95J33RE is a parametric equivalent with identical electrical and physical specifications. The primary difference is RoHS compliance status: the 95J33RE is ROHS3 compliant while the 95J33R is RoHS non-compliant. Both maintain the same Series 90 designation and dimensions.

Q: Are all substitute parts suitable for high-temperature applications? A: All parts listed share the same temperature coefficient of ±30ppm/°C. Operating temperature limits are not specified in the provided data. Verify specific operating temperature requirements against application needs.

Q: Does the axial package type remain consistent across all substitutes? A: Yes. All parts—95J33R, 25J33R, and 95J33RE—use axial through-hole packaging with two terminations, ensuring compatibility with standard axial resistor footprints.

Q: Which substitute should be selected for new designs? A: The 95J33RE is recommended for new designs due to ROHS3 compliance. The 25J33R is suitable where Series 20 designation is acceptable and physical dimension tolerance of approximately 0.012" diameter and 0.047" length variation is accommodated in the PCB layout.
