Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 45J10K is determined by strict equivalence across the following parameters: resistance value (10 kOhms), tolerance (±5%), power rating (5W), composition (wirewound), package configuration (axial), temperature coefficient (±20ppm/°C), and physical dimensions (0.343" Dia x 0.937" L). The identified substitute, 45J10KE, maintains complete parametric equivalence across all electrical and mechanical specifications. Substitution differences are limited to packaging format (bulk versus standard) and RoHS compliance status, neither of which affects functional interchangeability in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

Both the 45J10K and 45J10KE are active products from Ohmite with identical electrical performance and mechanical form factors. Selection between these parts should be based on compliance requirements and packaging needs. The 45J10KE offers ROHS3 compliance, making it suitable for applications subject to RoHS directives. The 45J10K remains available for applications where RoHS compliance is not a requirement. Both parts carry identical ECCN (EAR99) and HTSUS (8533.21.0080) classifications. Packaging format differences (bulk versus standard) do not affect circuit performance and should be selected based on procurement and assembly workflow requirements.

Frequently Asked Questions (FAQ)

Q: Are the 45J10K and 45J10KE electrically identical? A: Yes. Both parts share identical resistance (10 kOhms), tolerance (±5%), power rating (5W), temperature coefficient (±20ppm/°C), and wirewound composition. They are direct functional equivalents.

Q: What is the difference between the 45J10K and 45J10KE? A: The primary differences are packaging format (standard versus bulk) and RoHS compliance status. The 45J10KE is ROHS3 compliant, while the 45J10K is RoHS non-compliant. Electrical and mechanical specifications are identical.

Q: Can I substitute the 45J10KE for the 45J10K in existing designs? A: Yes, the 45J10KE is a direct substitute for the 45J10K. The identical axial package dimensions (0.343" Dia x 0.937" L) and electrical parameters ensure pin-for-pin and functional compatibility.

Q: Which part should I select for new designs? A: For applications requiring RoHS compliance, select the 45J10KE. For applications without RoHS requirements, either part is suitable. Verify compliance requirements for your specific application and regulatory jurisdiction.

Q: Are there any thermal or reliability differences between these parts? A: No. Both parts share identical temperature coefficients (±20ppm/°C), power ratings (5W), and series designation (Ohmicone® 40). Thermal and reliability performance are equivalent.
