Substitute Part Grouping Explanation

The Littelfuse 01250002Z qualifies as a direct substitute for the 01250002H based on identical electrical and mechanical parameters. Substitution is valid when the following criteria are met:

• Current rating: 30 A (identical)
• Voltage rating: 600V (identical)
• Fuse size: 0.394" Dia (10mm) (identical)
• Fuse type: Cartridge (identical)
• Fuseholder type: Clip (identical)
• Number of circuits: 1 (identical)
• Mounting type: Chassis Mount (identical)
• Termination style: Solder Lug (identical)
• Contact material: Beryllium Copper (identical)
• Contact finish: Silver (identical)
• RoHS compliance: ROHS3 Compliant (identical)

The primary distinction between these parts is product status and packaging configuration, not functional or electrical characteristics.

Parameter Comparison

Engineering Selection Recommendations

The Littelfuse 01250002Z is the direct equivalent for the obsolete 01250002H. Selection of the 01250002Z is appropriate for new designs and replacement applications due to its active product status and identical electrical and mechanical specifications. Both parts maintain ROHS3 compliance and are manufactured by Littelfuse Inc. within the 125 series.

The 01250002Z is available in bulk packaging, which may influence procurement decisions based on volume requirements and inventory management practices.
