Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the H25030-1Q is determined by the following critical parameters:

• Current Rating: 30 A
• Voltage Rating: 250V
• Fuse Type: Cartridge
• Fuse Size: 0.563" Dia x 2" L (14.3mm x 50.8mm)
• Number of Circuits: 1
• Mounting Type: Chassis Mount
• Termination Style: Quick Connect - 0.250" (6.3mm)
• Fuse Compatibility: Class H(K), Class R Fuses

The substitute part HM25030-1QR maintains electrical equivalence through identical current and voltage ratings, fuse type, and circuit configuration. Both parts are manufactured by Eaton - Bussmann Electrical Division and comply with RoHS requirements, ensuring functional interchangeability in applications requiring 30 A, 250V single-circuit cartridge fuse block assemblies.

Parameter Comparison

Engineering Selection Recommendations

The HM25030-1QR is the direct substitute for the obsolete H25030-1Q. Both components share identical electrical specifications (30 A, 250V), mechanical form factor (cartridge fuse block, chassis mount), and circuit configuration (single circuit). The substitute part is currently in active production status, whereas the original part is obsolete.

Both parts maintain RoHS compliance and are classified under the same ECCN and HTSUS codes, confirming regulatory and trade classification equivalence. The transition from H25030-1Q to HM25030-1QR does not require design modifications or system reconfiguration, as all critical parameters remain unchanged.

Frequently Asked Questions (FAQ)

Q: Can HM25030-1QR be used as a direct replacement for H25030-1Q?

A: Yes. Both parts are manufactured by Eaton - Bussmann Electrical Division and share identical electrical ratings (30 A, 250V), fuse type (cartridge), circuit configuration (1 circuit), and mounting specifications (chassis mount with quick connect termination). The substitute part is currently in active production.

Q: What are the key parameters that determine substitution compatibility?

A: Substitution is based on current rating (30 A), voltage rating (250V), fuse type (cartridge), fuse size (0.563" Dia x 2" L), number of circuits (1), mounting type (chassis mount), and termination style (quick connect 0.250"). All these parameters are identical between the main part and substitute.

Q: Does the packaging difference affect compatibility?

A: Packaging format (bulk versus other configurations) does not affect electrical or mechanical compatibility. The functional component specifications remain identical regardless of packaging method.

Q: Are there any compliance differences between the two parts?

A: Both parts are RoHS compliant and share identical ECCN (EAR99) and HTSUS (8538.90.8180) classifications. No compliance barriers exist for substitution.

Q: Why is the original part obsolete?

A: Product obsolescence is determined by manufacturer production decisions. The HM25030-1QR represents the current active equivalent, maintaining all functional specifications required for applications using the H25030-1Q.
