Substitute Part Grouping Explanation

Substitution eligibility for the SR-5H-2A-APH is determined by strict equivalence across the following parameters:

Current Rating: 2 A (exact match required)
Voltage Rating (AC): 300 V (exact match required)
Response Time: Slow Blow (exact match required)
Mounting Type: Through Hole (exact match required)
Package / Case: Radial, Can, Vertical (exact match required)
Breaking Capacity @ Rated Voltage: 100 A (exact match required)
Melting I²t: 30 (exact match required)
Size / Dimension: 0.335" Dia x 0.362" H (8.50mm x 9.20mm) (exact match required)
DC Cold Resistance: 0.031 Ohms (exact match required)
Series: SR-5H (exact match required)

Parts meeting all these criteria are classified as parametric equivalents and direct substitutes.
