Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the Ohmite 45F600 are qualified based on the following critical parameters:

• Resistance Value: Must be 600 Ohms
• Tolerance: Must be ±1%
• Power Rating: Must be 5W
• Composition: Must be Wirewound
• Package Type: Must be Axial
• Terminations: Must be 2-terminal configuration

The substitute parts listed below meet all these core electrical and mechanical requirements, ensuring functional equivalence in circuit applications. Variations in temperature coefficient, physical dimensions, and compliance certifications are noted but do not affect primary substitution eligibility.

Parameter Comparison

Engineering Selection Recommendations

45F600E (Ohmite): This part is the direct equivalent to the 45F600, maintaining identical electrical specifications and physical dimensions. The primary distinction is packaging format (Bulk) and RoHS3 compliance status. Selection of this part is appropriate when RoHS3 compliance is required or when bulk packaging aligns with procurement workflows.

ALSR05600R0FE12 (Vishay Dale): This part meets all core electrical requirements and achieves RoHS3 compliance. The temperature coefficient is ±30ppm/°C compared to ±20ppm/°C for the Ohmite variants, and physical dimensions are slightly smaller (0.312" Dia x 0.875" L versus 0.343" Dia x 0.937" L). The ALSR series includes moisture-resistant construction and operates across -65°C to 250°C. Selection of this part is appropriate when cross-manufacturer sourcing is required, when moisture resistance is beneficial, or when the smaller form factor accommodates space constraints.

Frequently Asked Questions (FAQ)

Q: Can the 45F600E be used as a direct replacement for the 45F600?

A: Yes. Both parts share identical resistance (600 Ohms), tolerance (±1%), power rating (5W), composition (Wirewound), package type (Axial), and physical dimensions. The primary difference is RoHS3 compliance status and packaging format.

Q: What is the key difference between the Ohmite 45F600 and the Vishay Dale ALSR05600R0FE12?

A: Both parts meet the core electrical specifications. The ALSR05600R0FE12 has a slightly higher temperature coefficient (±30ppm/°C versus ±20ppm/°C), smaller physical dimensions, moisture-resistant construction, and a wider operating temperature range (-65°C to 250°C). These differences do not affect functional substitution in standard applications.

Q: Are there physical space considerations when substituting with the ALSR05600R0FE12?

A: Yes. The ALSR05600R0FE12 has smaller dimensions (0.312" Dia x 0.875" L) compared to the Ohmite parts (0.343" Dia x 0.937" L). Verify that the reduced size accommodates your PCB layout and mounting requirements.

Q: Which substitute part should I select for RoHS3 compliance?

A: Both the 45F600E and ALSR05600R0FE12 are ROHS3 Compliant. The 45F600 is RoHS non-compliant. Select either substitute based on availability, packaging preference, and other application-specific requirements.

Q: Can I use these parts interchangeably in high-temperature applications?

A: The ALSR05600R0FE12 operates across -65°C to 250°C, providing a wider temperature range than the Ohmite variants. If your application requires operation beyond standard temperature ranges, the ALSR05600R0FE12 is the appropriate selection.
