Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 43F680 are identified based on electrical and mechanical parameter equivalence. The primary substitution criterion is functional compatibility, determined by matching the following parameters:

• Resistance value: 680 Ohms
• Tolerance: ±1%
• Power rating: 3W
• Composition: Wirewound
• Package configuration: Axial
• Temperature coefficient: ±20ppm/°C
• Physical dimensions: 0.220" Dia x 0.594" L (5.60mm x 15.10mm)

The 43F680E is a direct equivalent manufactured by Ohmite with identical electrical specifications and physical form factor. Packaging configuration differs (Bulk versus standard packaging), and compliance certifications vary between the main part and substitute.

Parameter Comparison

Engineering Selection Recommendations

Both the 43F680 and 43F680E are Active status components manufactured by Ohmite with identical electrical and mechanical specifications. Selection between these parts is determined by compliance requirements and packaging needs.

The 43F680E is RoHS Compliant with specified operating temperature range of -55°C ~ 275°C and MSL rating of 1 (Unlimited). The 43F680 is RoHS non-compliant with unspecified operating temperature range and MSL classification of Not Applicable.

For applications requiring RoHS compliance or extended environmental specifications, the 43F680E is the appropriate selection. Both parts are functionally equivalent for circuit applications requiring 680 Ohms ±1% at 3W with wirewound axial construction.

Frequently Asked Questions (FAQ)

Q: Are the 43F680 and 43F680E electrically identical?

A: Yes. Both parts have identical resistance value (680 Ohms), tolerance (±1%), power rating (3W), temperature coefficient (±20ppm/°C), and wirewound composition. They are functionally equivalent for circuit applications.

Q: What is the difference between the 43F680 and 43F680E?

A: The primary differences are packaging configuration (standard versus Bulk), RoHS compliance status (non-compliant versus Compliant), and specified operating temperature range (-55°C ~ 275°C for the 43F680E). The 43F680E includes MSL rating of 1 (Unlimited).

Q: Can I use the 43F680E as a direct replacement for the 43F680?

A: Yes. The 43F680E is a direct substitute with identical electrical specifications and physical dimensions (0.220" Dia x 0.594" L). Substitution is valid for all circuit applications where the 43F680 is specified.

Q: Which part should I select for new designs?

A: Selection depends on compliance requirements. For RoHS-compliant applications, select the 43F680E. Both parts are Active status and suitable for production use.

Q: Are the physical dimensions identical?

A: Yes. Both parts have identical dimensions of 0.220" Dia x 0.594" L (5.60mm x 15.10mm) and axial package configuration. They are mechanically interchangeable.
