Key Parameters

Substitute Part Grouping Explanation

Substitution for the H25030-3C is determined by strict alignment of the following critical parameters:

• Current Rating: 30 A
• Voltage Rating: 250V
• Number of Circuits: 3
• 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: Box Lug
• Fuse Compatibility: Class H(K), Class R Fuses

The substitute part HM25030-3CR meets all these electrical and mechanical parameters, making it a direct functional equivalent. The primary distinction is product status: HM25030-3CR is active and RoHS compliant, whereas H25030-3C is obsolete.

Parameter Comparison

Engineering Selection Recommendations

The HM25030-3CR is the direct substitute for the H25030-3C. Both components share identical electrical ratings (30A, 250V, 3-circuit), mechanical dimensions, and fuse compatibility specifications. The HM25030-3CR is currently in active production status with RoHS compliance certification, making it suitable for new designs and replacement applications where regulatory compliance is required. The H25030-3C, being obsolete, should be replaced with HM25030-3CR for long-term supply chain continuity and regulatory adherence.

Frequently Asked Questions (FAQ)

Q: Can HM25030-3CR be used as a direct replacement for H25030-3C?

A: Yes. Both parts are identical in electrical rating (30A, 250V), circuit count (3), fuse type (cartridge), physical dimensions (0.563" Dia x 2" L), mounting configuration (chassis mount), and termination style (box lug). The HM25030-3CR is the active production equivalent.

Q: What is the difference between H25030-3C and HM25030-3CR?

A: The H25030-3C is obsolete, while HM25030-3CR is active production. HM25030-3CR carries RoHS compliance certification. All functional and mechanical parameters are identical.

Q: Are there packaging differences between these parts?

A: H25030-3C is supplied in standard packaging, while HM25030-3CR is supplied in bulk packaging. This does not affect electrical or mechanical compatibility.

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

A: Both the H25030-3C and HM25030-3CR are designed for use with Class H(K) and Class R cartridge fuses rated for 30A at 250V with dimensions 0.563" Dia x 2" L.

Q: Is HM25030-3CR suitable for new equipment designs?

A: Yes. HM25030-3CR is active production and RoHS compliant, making it appropriate for new designs and applications requiring regulatory compliance.
