Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the Ohmite 95J18R are qualified based on matching the following critical parameters: resistance value (18 Ohms), tolerance (±5%), power rating (5W), composition (wirewound), package type (axial), temperature coefficient (±30ppm/°C), and functional features (flame retardant coating with safety designation). All substitute parts maintain identical electrical specifications and are compatible with applications designed for the 95J18R. Physical dimensions may vary within acceptable tolerances for axial through-hole mounting.

Parameter Comparison

Engineering Selection Recommendations

The 95J18RE serves as the primary parametric equivalent to the 95J18R, offering identical electrical specifications and physical dimensions while providing RoHS3 compliance. This substitution is appropriate for applications requiring environmental compliance certification. The 25J18R functions as a manufacturer-recommended alternative within the Ohmite product line, maintaining all critical electrical parameters with minor dimensional variation acceptable for standard through-hole mounting applications. Both substitute parts carry Active product status, ensuring continued availability and manufacturing support. Selection between substitutes should be based on compliance requirements and packaging preferences rather than electrical performance, as all three parts are electrically interchangeable.

Frequently Asked Questions (FAQ)

Q: Are the 95J18R, 25J18R, and 95J18RE electrically interchangeable?

A: Yes. All three parts share identical resistance value (18 Ohms), tolerance (±5%), power rating (5W), temperature coefficient (±30ppm/°C), and functional features (flame retardant coating with safety designation). They are direct electrical substitutes.

Q: What is the primary difference between these substitute parts?

A: The 95J18RE provides RoHS3 compliance, whereas the 95J18R and 25J18R are RoHS non-compliant. The 25J18R belongs to the Ohmite Series 20 product line and has slightly larger physical dimensions (0.276" Dia x 1.016" L) compared to the 95J18R and 95J18RE (0.264" Dia x 0.969" L).

Q: Can the 25J18R be used in place of the 95J18R despite dimensional differences?

A: Yes, for standard through-hole axial mounting applications. The dimensional variation is within acceptable tolerances for PCB layouts designed for axial resistors. Verify PCB footprint spacing if space constraints are critical.

Q: Which substitute should I select for new designs?

A: The 95J18RE is recommended for new designs requiring environmental compliance, as it maintains RoHS3 certification while preserving all electrical and mechanical specifications of the original 95J18R.

Q: Are all parts available in the same packaging formats?

A: The 95J18R packaging is listed as standard, while both 25J18R and 95J18RE are available in Bulk packaging. Verify packaging availability with your supplier based on procurement requirements.
