Key Parameters

Substitute Part Grouping Explanation

Substitute identification for the CB2258-1 is based on the following critical parameters that define functional compatibility:

• Fuse size accommodation: 22mm x 58mm cartridge fuse compatibility
• Current rating: 25 A minimum capacity
• Voltage rating: 690V minimum rating
• Mounting configuration: DIN rail compatibility
• Circuit count: Single circuit (1P) configuration
• Termination method: Screw terminal connection

The substitute part 002570001 from Altech Corporation is identified as an equivalent based on these core electrical and mechanical parameters. This substitute maintains the essential functional characteristics required for direct replacement in applications utilizing 22mm x 58mm cartridge fuses at 25 A and 690V.

Parameter Comparison

Engineering Selection Recommendations

The substitute part 002570001 is an active product from Altech Corporation with current manufacturing support and regulatory compliance certifications. The CB2258-1, being obsolete, has no ongoing availability or technical support. Selection of 002570001 provides access to a currently manufactured component with ROHS3 compliance and REACH unaffected status, ensuring compatibility with modern regulatory requirements and supply chain continuity.

The higher current rating of 002570001 (100 A versus 25 A) does not preclude its use as a substitute in applications designed for 25 A operation, as fuse holders with higher current ratings can safely accommodate lower-rated fuses. The 690V rating is maintained across both components, ensuring voltage compatibility.

Frequently Asked Questions (FAQ)

Q: Can 002570001 directly replace CB2258-1 in existing installations?

A: Yes. Both components are manufactured by Altech Corporation and share the same voltage rating (690V) and single-circuit configuration. The substitute maintains compatibility with 22mm x 58mm cartridge fuses. The higher current rating of 002570001 does not prevent its use in 25 A applications.

Q: What is the significance of the current rating difference between CB2258-1 (25 A) and 002570001 (100 A)?

A: Fuse holder current ratings indicate the maximum current the holder can safely conduct. A holder rated for 100 A can safely operate in circuits rated for 25 A. The fuse element itself determines the actual circuit protection level, not the holder rating.

Q: Are there compliance differences between these components?

A: CB2258-1 carries no specified compliance certifications in available documentation. 002570001 is ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards for electronic components.

Q: Why is CB2258-1 listed as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production and no longer provides technical support or warranty coverage. 002570001 is an active product with ongoing manufacturing support.

Q: What packaging is available for 002570001?

A: 002570001 is supplied in bulk packaging, with 841 pieces currently in stock as new original inventory.
