Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 80F7R5 are identified based on the following critical parameters that determine functional equivalence:

• Resistance value: 7.5 Ohms
• Tolerance: ±1%
• Power rating: 10W
• Composition: Wirewound
• Package type: Axial
• Number of terminations: 2

The 40F7R5 from Ohmite qualifies as a substitute based on matching these core electrical and mechanical specifications. Both parts deliver identical resistance, tolerance, and power handling characteristics within the same package configuration, enabling direct substitution in circuit applications where these parameters are specified.

Parameter Comparison

Engineering Selection Recommendations

Both the 80F7R5 and 40F7R5 maintain Active product status and share identical HTSUS and ECCN classifications. Selection between these parts should be based on availability and packaging requirements. The 80F7R5 is available in standard packaging with 1118 units in stock, while the 40F7R5 is supplied in bulk packaging with 1175 units available. Both parts carry RoHS non-compliant status and are subject to identical regulatory classifications. No performance differentiation exists between these parts for applications requiring 7.5 Ohm ±1% 10W axial wirewound resistors.

Frequently Asked Questions (FAQ)

Q: Can the 40F7R5 be used as a direct replacement for the 80F7R5?

A: Yes. Both parts share identical electrical specifications (7.5 Ohms, ±1% tolerance, 10W power rating) and mechanical configuration (axial wirewound package). Direct substitution is supported for applications where these parameters are specified.

Q: What is the primary difference between the 80F7R5 and 40F7R5?

A: The primary difference is packaging format. The 80F7R5 is supplied in standard packaging, while the 40F7R5 is supplied in bulk packaging. The 40F7R5 also specifies silicone composition for the wirewound element. Electrical and mechanical performance remain equivalent.

Q: Are there any compliance or regulatory differences between these parts?

A: No. Both parts carry identical RoHS non-compliant status, ECCN classification (EAR99), and HTSUS code (8533.21.0080). Regulatory treatment is equivalent.

Q: Which part should be selected for new designs?

A: Selection should be based on current inventory availability and packaging requirements. Both parts are Active status and suitable for new design implementation. The 40F7R5 offers higher current stock levels (1175 units) compared to the 80F7R5 (1118 units).

Q: Are temperature coefficient specifications identical?

A: The 80F7R5 specifies ±50ppm/°C temperature coefficient. Temperature coefficient data for the 40F7R5 is not provided in the available documentation. Verify temperature coefficient requirements for applications with strict thermal stability specifications.
