Substitute Part Grouping Explanation

The A64-113-271P521 qualifies as a direct substitute for the A64-112-271P521 based on matching electrical and mechanical parameters. Both parts share identical specifications across all critical substitution criteria:

• Connector type and port configuration (1-port RJ45)
• Mounting method and board interface (through-hole solder termination)
• Physical orientation and height above board (90° right-angle, 0.528")
• Electrical performance class (10/100 Base-T)
• Shielding and EMI protection (shielded with EMI finger)
• Mechanical features (board lock, tab direction)
• Material composition and environmental ratings (PBT/Polyester housing, ROHS3 compliant, MSL 1)

The primary distinction is product status: A64-112-271P521 is obsolete, while A64-113-271P521 is active with current inventory availability.

Parameter Comparison

Engineering Selection Recommendations

The A64-113-271P521 is the appropriate substitute for the obsolete A64-112-271P521. Both parts maintain identical electrical and mechanical specifications, ensuring direct compatibility in 10/100 Base-T applications. The A64-113-271P521 carries active product status with current manufacturing support and higher inventory availability (1246 units versus 1102 units), providing supply chain continuity. Both parts maintain equivalent compliance certifications: ROHS3 compliance, REACH unaffected status, and EAR99 export classification. The substitute part is available in tray packaging, which may differ from the original part's packaging specification but does not affect functional or mechanical compatibility.
