Ohmite 25J600 Equivalent & Substitute Parts

Part Overview

The Ohmite 25J600 is a 600 Ohm, 5% tolerance, 5W through-hole axial wirewound resistor with flame retardant coating and safety features. This component is classified as Active product status and is suitable for general-purpose power dissipation applications requiring wirewound construction. Substitute parts are identified when equivalent electrical specifications and mechanical compatibility are maintained across the allowed parameter set, enabling procurement flexibility and inventory optimization.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Ohmite 25J600 is determined by strict equivalence across the following parameters: resistance value (600 Ohms), tolerance (±5%), power rating (5W), composition (wirewound), package type (axial), temperature coefficient (±30ppm/°C), and termination count (2). All identified substitute parts maintain these electrical and mechanical specifications. Packaging format (bulk vs. standard) does not affect functional substitutability. Dimensional variations within the axial package category are permitted provided the component fits the intended circuit board layout and mounting constraints.

Parameter Comparison

Engineering Selection Recommendations

All three parts—25J600, 25J600E, and 95J600—are functionally equivalent and maintain Active product status. Selection should be based on regulatory compliance requirements and inventory availability.

The 25J600E is ROHS3 compliant and represents the preferred choice for applications subject to RoHS3 regulations. This part is available in bulk packaging with higher inventory levels (1340 pcs).

The 25J600 and 95J600 are RoHS non-compliant and suitable for applications without RoHS compliance mandates. The 25J600 maintains the original Series 20 designation with standard packaging. The 95J600 belongs to Series 90 and features slightly reduced physical dimensions (0.264" Dia x 0.969" L versus 0.276" Dia x 1.016" L), which may be advantageous in space-constrained layouts.

All parts carry identical electrical specifications and are suitable for direct substitution provided circuit board layout accommodates the dimensional variations noted above.

Frequently Asked Questions (FAQ)

Q: Can the 25J600E replace the 25J600 in all applications? A: Yes. The 25J600E maintains identical electrical specifications (600 Ohms, ±5%, 5W, wirewound, axial) and is physically compatible. The primary difference is ROHS3 compliance on the 25J600E, making it the preferred choice for regulated applications.

Q: What is the significance of the Series designation (20 vs. 90)? A: Series designation indicates the product line within Ohmite's wirewound resistor portfolio. Both Series 20 and Series 90 maintain equivalent electrical performance for this 600 Ohm, 5W specification. Series selection does not affect functional substitutability.

Q: Are there dimensional constraints when substituting the 95J600? A: The 95J600 has slightly smaller dimensions (0.264" Dia x 0.969" L) compared to the 25J600 (0.276" Dia x 1.016" L). Verify that the circuit board layout and mounting footprint accommodate these reduced dimensions. The smaller size may provide advantages in compact designs.

Q: What packaging formats are available? A: The 25J600 is supplied in standard packaging. Both 25J600E and 95J600 are available in bulk packaging, which may be relevant for high-volume procurement scenarios.

Q: Which part should be selected for new designs? A: For new designs subject to RoHS3 regulations, specify the 25J600E. For applications without RoHS compliance requirements, either the 25J600 or 95J600 may be selected based on inventory availability and dimensional fit.
