Substitute Part Grouping Explanation

Substitution eligibility for the Ohmite 45J150 is determined by strict equivalence across the following critical parameters:

• Resistance value: 150 Ohms
• Tolerance: ±5%
• Power rating: 5W
• Composition: Wirewound
• Package configuration: Axial
• Temperature coefficient: ±20ppm/°C
• Physical dimensions: 0.343" Dia x 0.937" L (8.70mm x 23.80mm)
• Number of terminations: 2

The substitute part 45J150E meets all electrical and mechanical specifications required for direct substitution. The primary distinction between the main part and its substitute is packaging configuration (tape and reel versus bulk) and RoHS compliance status.

Parameter Comparison

Engineering Selection Recommendations

Both the 45J150 and 45J150E are active production components from Ohmite's Ohmicone® 40 series and are electrically and mechanically identical. Selection between these parts should be based on the following criteria:

45J150 (Standard Packaging): Select this part number when standard packaging configuration is required and RoHS non-compliant components are acceptable for your application.

45J150E (Bulk Packaging): Select this part number when ROHS3 compliance is mandated by design requirements, regulatory standards, or customer specifications. The bulk packaging configuration is suitable for high-volume manufacturing environments with automated component handling systems.

Both parts carry identical electrical specifications, dimensional tolerances, and performance characteristics. The choice between them is driven by packaging requirements and regulatory compliance needs rather than functional performance.

Frequently Asked Questions (FAQ)

Q: Can 45J150E be used as a direct replacement for 45J150?

A: Yes. The 45J150E is electrically and mechanically equivalent to the 45J150. Both components have identical resistance values, tolerance, power rating, composition, package type, and physical dimensions. The primary differences are packaging configuration and RoHS compliance status.

Q: What is the difference between standard and bulk packaging?

A: Standard packaging (45J150) typically uses tape and reel or individual packaging suitable for standard component handling. Bulk packaging (45J150E) is configured for high-volume automated assembly processes. The electrical and mechanical specifications remain identical.

Q: Does RoHS compliance affect component performance?

A: No. RoHS compliance relates to material composition and environmental regulations, not electrical performance. Both the RoHS non-compliant 45J150 and ROHS3 compliant 45J150E deliver identical electrical characteristics and performance in circuit applications.

Q: Are the physical dimensions identical between both part numbers?

A: Yes. Both 45J150 and 45J150E have identical physical dimensions of 0.343" diameter by 0.937" length (8.70mm x 23.80mm). They are mechanically interchangeable in PCB layouts and through-hole applications.

Q: Which part should I specify for new designs?

A: Specify based on your regulatory and compliance requirements. If ROHS3 compliance is required, use 45J150E. If RoHS compliance is not a constraint, either part number is acceptable. Verify packaging requirements with your manufacturing process.
