Key Parameters

Substitute Part Grouping Explanation

Substitution for the H25030-1PR is based on the following critical parameters that must remain consistent:

• Voltage rating: 250V
• Current rating: 30A
• Number of circuits: 1
• Fuse type: Cartridge
• Fuse size: 0.563" Dia x 2" L (14.3mm x 50.8mm)
• Fuseholder type: Block
• Mounting type: Chassis Mount
• Termination style: Screw Terminal, Pressure Plate
• Compatibility with Class H(K) and Class R Fuses

The substitute part HM25030-1PR maintains all electrical and mechanical parameters required for direct substitution. The primary distinction is the product status transition from obsolete to active, along with RoHS compliance certification in the substitute model.

Parameter Comparison

Engineering Selection Recommendations

The HM25030-1PR is the direct substitute for the H25030-1PR. Both components share identical electrical ratings (250V, 30A, single circuit) and mechanical specifications (cartridge fuse type, block fuseholder, chassis mount configuration). The substitute part is currently in active production status, ensuring availability for replacement applications.

The HM25030-1PR carries RoHS compliance certification, which may be a requirement for new installations or systems subject to environmental regulations. Both parts are classified under the same ECCN and HTSUS codes, confirming their functional equivalence.

Frequently Asked Questions (FAQ)

Q: Can HM25030-1PR directly replace H25030-1PR in existing installations?

A: Yes. Both parts maintain identical voltage (250V), current (30A), circuit count (1), fuse type (cartridge), and mounting configuration (chassis mount). The electrical and mechanical compatibility is complete.

Q: What is the significance of the product status change from obsolete to active?

A: The H25030-1PR is obsolete and no longer manufactured. The HM25030-1PR is the active equivalent, ensuring continued availability for maintenance and replacement needs.

Q: Does RoHS compliance affect compatibility?

A: RoHS compliance in the HM25030-1PR indicates adherence to environmental standards for hazardous substance restrictions. This does not affect electrical or mechanical compatibility with systems designed for the H25030-1PR.

Q: Are there packaging differences between these parts?

A: The H25030-1PR is listed with standard packaging, while the HM25030-1PR is supplied in bulk packaging. The component itself remains functionally identical.

Q: What fuse classes are compatible with these fuse blocks?

A: Both the H25030-1PR and HM25030-1PR are designed for use with Class H(K) and Class R cartridge fuses.

Q: Are there any differences in termination or mounting that would affect installation?

A: Both parts feature screw terminal and pressure plate termination with chassis mount configuration. Installation procedures remain consistent between the two models.
