Substitute Part Grouping Explanation

Substitution of the TCFH30 is determined by strict equivalence across the following critical parameters:

• Current Rating: 30 A
• Voltage Rating: 600V
• Fuse Size: 0.75" W x 1.88" L (19.1mm x 47.8mm)
• Number of Circuits: 1
• Mounting Type: DIN Rail
• Fuse Type: Radial
• Fuseholder Type: Block
• Termination Style: Screw Terminal
• Contact Material: Copper Alloy
• Contact Finish: Tin
• Series: CUBEFuse® TCFH

The TCFH30N qualifies as a direct substitute because it maintains identical electrical ratings, mechanical dimensions, mounting configuration, and contact specifications. The primary distinction is product status: TCFH30N is Active, whereas TCFH30 is Obsolete.

Parameter Comparison

Engineering Selection Recommendations

The TCFH30N is the direct substitute for the obsolete TCFH30. Both components share identical electrical specifications (30 A, 600V), mechanical dimensions, and mounting characteristics. The TCFH30N maintains Active product status and is ROHS3 Compliant, making it the appropriate choice for new designs and replacement applications requiring TCFH30 functionality.

Both parts carry REACH Unaffected status and EAR99 export classification, ensuring regulatory consistency across substitution.

Frequently Asked Questions (FAQ)

Q: Can TCFH30N directly replace TCFH30 in existing installations?

A: Yes. The TCFH30N is electrically and mechanically equivalent to TCFH30. Both components have identical current ratings (30 A), voltage ratings (600V), fuse dimensions (0.75" W x 1.88" L), DIN rail mounting, and screw terminal connections. Direct substitution is appropriate.

Q: What is the difference between TCFH30 and TCFH30N?

A: The primary difference is product status. TCFH30 is Obsolete, while TCFH30N is Active. TCFH30N also carries ROHS3 Compliance certification. All electrical and mechanical parameters are identical.

Q: Are there packaging differences between these parts?

A: TCFH30 packaging is listed as standard, while TCFH30N is supplied in Bulk packaging. This distinction affects order quantities and handling but does not impact electrical or mechanical compatibility.

Q: What compliance certifications apply to both parts?

A: Both TCFH30 and TCFH30N are REACH Unaffected and classified as EAR99 for export purposes. TCFH30N additionally carries ROHS3 Compliance certification.

Q: Are these parts suitable for 600V applications?

A: Yes. Both components are rated for 600V operation and are designed for use in 600V electrical systems with 30 A circuit protection requirements.
