Key Parameters

Substitute Part Grouping Explanation

Substitution of the P5103AC60 is determined by matching the following critical electrical and mechanical parameters:

• Voltage ratings: Breakover voltage of 600V, off-state voltage of 420V, and on-state voltage of 8V
• Current specifications: Peak pulse current of 150A (8/20µs) and 45A (10/1000µs), with hold current of 150mA
• Element configuration: Three-element design
• Capacitance characteristics: 40pF and 60pF values
• Package compatibility: 3-SIP configuration with TO-220 Modified supplier package
• Through-hole mounting requirement

The P5103ACL60 meets all these parameters identically, establishing it as a direct electrical and mechanical equivalent.

Parameter Comparison

Engineering Selection Recommendations

The P5103ACL60 is the direct substitute for the obsolete P5103AC60. Both components are manufactured by Littelfuse Inc. and share identical electrical specifications and mechanical packaging. The primary distinction is product status and regulatory compliance: the P5103ACL60 is active in production and ROHS3 compliant, whereas the P5103AC60 is obsolete and RoHS non-compliant. For new designs or ongoing procurement, the P5103ACL60 is the appropriate selection. Both components maintain identical moisture sensitivity levels and export classifications.

Frequently Asked Questions (FAQ)

Q: Can P5103ACL60 be used as a direct replacement for P5103AC60?
