Substitute Part Grouping Explanation

Substitution of the obsolete TE Connectivity 416PA504M is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part must match the following criteria:

• Resistance value of 500 kOhms
• Power rating of 0.2W (1/5W)
• Tolerance of ±25%
• Temperature coefficient of ±250ppm/°C
• Single-turn adjustment mechanism
• Top adjustment configuration
• Cermet resistive material composition
• Through-hole mounting with PC pin termination
• Rectangular form factor with 0.319" x 0.268" face dimensions (8.10mm x 6.80mm)
• ROHS3 compliance
• MSL rating of 1 (Unlimited)

The Bourns 3306F-1-504 meets all specified parameters and is classified as an active product, providing continuity for applications currently utilizing the discontinued TE Connectivity component.
