Key Parameters

Substitute Part Grouping Explanation

The 170M6813D qualifies as a direct substitute for the 170M6813 based on identical electrical and mechanical parameters:

• Current Rating: 900A (identical)
• Voltage Rating: 700 VAC (identical)
• Fuse Type: Square (identical)
• Package / Case: Rectangular, Blade (identical)
• Physical Dimensions: 2.677" L x 2.992" W x 3.465" H (identical)
• Breaking Capacity: 200kA (identical)
• Melting I²t: 100000 (identical)
• Mounting Type: Requires Holder (identical)

The substitution is valid because all critical electrical performance parameters and mechanical form factors remain unchanged between the two parts.

Parameter Comparison

Engineering Selection Recommendations

The 170M6813D is the appropriate selection for new designs and replacement applications. The obsolete status of the 170M6813 necessitates transition to the active equivalent. The 170M6813D maintains full electrical and mechanical compatibility while providing:

• Active product status ensuring continued availability
• Extended compliance certifications (CE and UR versus UR only)
• RoHS compliance certification
• Bulk packaging option for production environments

Both parts share identical electrical performance characteristics, breaking capacity, and physical form factor, ensuring direct interchangeability in existing holder assemblies and circuit protection applications.

Frequently Asked Questions (FAQ)

Q: Can 170M6813D replace 170M6813 in existing installations?

A: Yes. The 170M6813D is electrically and mechanically identical to the 170M6813. Both parts have the same current rating (900A), voltage rating (700 VAC), physical dimensions, breaking capacity (200kA), and mounting requirements. Direct substitution is valid.

Q: What is the difference between the two part numbers?

A: The 170M6813D is the active production equivalent of the obsolete 170M6813. The primary differences are product status (active versus obsolete), packaging format (bulk), and expanded compliance certifications (CE added to existing UR approval).

Q: Are there any compatibility concerns with the holder assembly?

A: No. Both parts use identical rectangular blade package geometry and require the same holder type. Physical dimensions are 2.677" L x 2.992" W x 3.465" H for both parts.

Q: What certifications apply to each part?

A: The 170M6813 carries UR approval. The 170M6813D carries both CE and UR approvals, providing broader regulatory acceptance. The 170M6813D also meets RoHS compliance requirements.

Q: Is the melting I²t value the same?

A: Yes. Both parts have a melting I²t of 100000, ensuring identical thermal protection characteristics.
