Substitute Part Grouping Explanation

Substitution for the RS0107R500FS73 is determined by matching the following critical electrical and mechanical parameters:

• Resistance value: 7.5 Ohms
• Tolerance: ±1%
• Power rating: 10W
• Composition: Wirewound
• Package configuration: Axial through-hole

The substitute part 40F7R5 from Ohmite meets these core electrical specifications. Both parts are wirewound axial resistors rated for 10W at 7.5 Ohms with ±1% tolerance. Packaging differences (Tape & Reel versus Bulk) reflect inventory and procurement formats rather than functional incompatibility.

Parameter Comparison

Engineering Selection Recommendations

Both the RS0107R500FS73 and 40F7R5 are active production components with identical electrical specifications and regulatory classifications. Selection between these parts should be based on:

• Packaging format requirements (Tape & Reel versus Bulk)
• Inventory availability and lead times
• Procurement cost and volume pricing
• Existing supplier relationships and qualification status

Both parts carry RoHS non-compliant status and EAR99 export classification. No functional performance difference exists between these components when applied within their specified operating parameters.

Frequently Asked Questions (FAQ)

Q: Can the 40F7R5 be used as a direct replacement for the RS0107R500FS73?

A: Yes. Both components share identical electrical specifications: 7.5 Ohms, ±1% tolerance, 10W power rating, and wirewound axial construction. They are functionally equivalent for circuit applications.

Q: What is the difference between Tape & Reel and Bulk packaging?

A: Tape & Reel packaging is used for automated assembly processes, while Bulk packaging is used for manual assembly or stock management. The components themselves are identical; packaging format affects handling and assembly methodology only.

Q: Are there any compliance differences between these parts?

A: No. Both parts share the same RoHS status (non-compliant), ECCN classification (EAR99), and HTSUS code (8533.21.0080).

Q: What operating temperature range applies to both parts?

A: The RS0107R500FS73 is rated for -65°C to 250°C operation. Operating temperature specifications for the 40F7R5 were not provided in the available data.

Q: How do I verify compatibility in my specific application?

A: Confirm that your circuit design requires a 7.5 Ohm, 10W, ±1% tolerance wirewound axial resistor. Both parts meet these specifications and are suitable for direct substitution in such applications.
