Key Parameters

Substitute Part Grouping Explanation

The Littelfuse 01530002H qualifies as a direct substitute based on the following critical parameters that determine functional compatibility:

Matching Parameters:

• Series 153 blade fuse holder family
• Identical fuse size: 0.433" L x 0.152" W (11.00mm x 3.85mm)
• Free hanging (in-line) mounting configuration
• Single circuit design
• Miniature (ATM) fuse compatibility
• Crimp termination style
• Copper alloy contacts with tin finish
• ROHS3 compliance

Substitution Basis: The 01530002H is an active production part within the same Littelfuse 153 series, maintaining mechanical and electrical interface compatibility with the obsolete 01530029Z. Both holders accommodate identical miniature blade fuse dimensions and employ equivalent contact materials and termination methods.

Parameter Comparison

Engineering Selection Recommendations

The Littelfuse 01530002H is the designated manufacturer substitute for the obsolete 01530029Z. Selection of the 01530002H is supported by:

• Active production status ensuring long-term availability and supply chain continuity
• Identical mechanical interface dimensions for direct mounting compatibility
• Equivalent electrical specifications for circuit protection applications
• ROHS3 compliance maintaining regulatory alignment with the original part
• Bulk packaging availability for production quantities

The substitute part maintains all critical functional parameters required for miniature blade fuse holder applications in 32V circuits.

Frequently Asked Questions (FAQ)

Q: Can the 01530002H directly replace the 01530029Z in existing assemblies?

A: Yes. Both parts share identical fuse size dimensions (0.433" L x 0.152" W), mounting configuration (free hanging in-line), and termination style (crimp). The mechanical and electrical interfaces are fully compatible.

Q: What is the primary reason for substitution?

A: The 01530029Z is obsolete. The 01530002H is an active production part within the same Littelfuse 153 series, providing equivalent functionality with assured supply availability.

Q: Are there voltage rating differences between these parts?

A: The 01530029Z specifies 32V. The 01530002H does not list a voltage specification in the provided data. Both parts are designed for miniature blade fuse applications within the 153 series. Application voltage requirements should be evaluated against circuit specifications.

Q: What is the current rating of the 01530002H?

A: The 01530002H is rated for 20A. Current rating is a fuse characteristic, not a fuseholder characteristic. The holder accommodates miniature ATM fuses regardless of the fuse's current rating.

Q: Are packaging options different?

A: The 01530029Z packaging is unspecified. The 01530002H is available in bulk packaging, suitable for production quantities.

Q: Do both parts meet RoHS requirements?

A: Yes. Both the 01530029Z and 01530002H are ROHS3 compliant.
