LH600301PR Equivalent & Substitute Parts

Part Overview

The LH600301PR is a cartridge fuse block rated for 30 A at 600V with single-circuit configuration and chassis mount orientation. Manufactured by Littelfuse Inc., this component is classified as obsolete product status. Identifying equivalent and substitute parts is necessary due to discontinued availability and the need for sourcing alternatives that maintain electrical and mechanical compatibility within the specified parameter constraints.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the LH600301PR is based on electrical and mechanical parameter alignment. The primary substitute, LFH600301PID, maintains compatibility through the following critical parameters:

• Current Rating: 30 A (identical)
• Voltage Rating: 600V (identical)
• Fuse Type: Cartridge (identical)
• Fuseholder Type: Block (identical)
• Number of Circuits: 1 (identical)
• Termination Style: Screw Terminal, Pressure Plate (identical)
• Fuse Compatibility: Class H(K), Class R Fuses (identical)

The primary difference between these parts is the mounting configuration: LH600301PR uses chassis mount, while LFH600301PID uses DIN rail mount. This distinction requires evaluation based on the specific installation environment and available mounting infrastructure.

Parameter Comparison

Engineering Selection Recommendations

The LFH600301PID serves as the direct electrical and functional substitute for the LH600301PR. Both components share identical electrical ratings (30 A, 600V), fuse type (cartridge), and circuit configuration (single circuit). The LFH600301PID is currently in active production status, ensuring availability and supply chain continuity.

The LFH600301PID carries ROHS3 compliance certification, whereas the LH600301PR is RoHS non-compliant. Selection between these parts should account for regulatory requirements applicable to the end application and geographic market.

The mounting configuration difference—chassis mount versus DIN rail—represents the primary mechanical distinction. Component selection must align with the available mounting infrastructure in the target installation environment.

Frequently Asked Questions (FAQ)

Q: Can LFH600301PID directly replace LH600301PR in all applications?

A: Electrical and functional compatibility is confirmed across all specified parameters. Mounting configuration differs (DIN rail versus chassis mount), requiring assessment of the installation environment. If the application requires chassis mount specifically, alternative solutions must be evaluated.

Q: What are the key electrical parameters that define substitution eligibility?

A: Current rating (30 A), voltage rating (600V), fuse type (cartridge), fuseholder type (block), circuit count (1), and fuse compatibility (Class H(K), Class R) must remain constant for substitution validity.

Q: Does the RoHS compliance difference affect substitution suitability?

A: RoHS compliance status reflects regulatory and environmental standards applicable to manufacturing and end-of-life disposal. Selection should account for applicable regulations in the target market and application requirements.

Q: Are there inventory considerations for component selection?

A: LFH600301PID is currently in active production with confirmed stock availability. LH600301PR is obsolete. For new designs or replenishment, LFH600301PID represents the current production alternative.
