Substitute Part Grouping Explanation

Substitute parts for the TWM5J680 are identified based on strict electrical and mechanical parameter matching within the Ohmite TWM series. The substitution criteria are:

• Resistance value: 680 Ohms (exact match required)
• Tolerance: ±5% (exact match required)
• Power rating: 5W (exact match required)
• Composition: Metal Oxide Film (exact match required)
• Package configuration: Radial (exact match required)
• Operating temperature range: -55°C to 275°C (exact match required)
• Temperature coefficient: ±350ppm/°C (exact match required)
• Physical dimensions and termination count: Must be identical

The TWM5J680E meets all substitution criteria and is classified as an active product, making it a direct equivalent for the obsolete TWM5J680.

Parameter Comparison

Engineering Selection Recommendations

The TWM5J680E is the direct substitute for the obsolete TWM5J680. Both components are manufactured by Ohmite within the same TWM series and share identical electrical and mechanical specifications.

The primary distinction is product status and regulatory compliance. The TWM5J680E is an active product with ROHS3 compliance, whereas the TWM5J680 is obsolete and RoHS non-compliant. For new designs and production applications, the TWM5J680E is the appropriate selection. For legacy system repairs requiring exact component matching, the TWM5J680E maintains full functional and physical compatibility with the original specification.

Frequently Asked Questions (FAQ)

Q: Can TWM5J680E be used as a direct replacement for TWM5J680?

A: Yes. The TWM5J680E is a direct substitute. All electrical parameters (resistance, tolerance, power rating, temperature coefficient, operating temperature range) and mechanical specifications (package type, dimensions, termination count) are identical.

Q: What is the difference between TWM5J680 and TWM5J680E?

A: The TWM5J680E is the active production variant of the TWM5J680 series. The primary differences are product status (active versus obsolete) and RoHS compliance (ROHS3 compliant versus non-compliant). Electrical and mechanical performance are equivalent.

Q: Are there any packaging differences between these parts?

A: The TWM5J680 is supplied in standard packaging, while the TWM5J680E is supplied in bulk packaging. Both maintain identical radial package configuration, dimensions, and termination specifications. Packaging format does not affect component performance or compatibility.

Q: What compliance certifications apply to these resistors?

A: Both parts carry EAR99 export classification and are REACH Unaffected. The TWM5J680E additionally meets ROHS3 compliance requirements. Both components are classified under HTSUS code 8533.21.0090.

Q: Can these resistors be used in high-temperature applications?

A: Yes. Both the TWM5J680 and TWM5J680E are rated for continuous operation across -55°C to 275°C with a temperature coefficient of ±350ppm/°C, making them suitable for high-temperature industrial and aerospace applications.
