• Tolerance: ±10% (identical)
• Temperature coefficient: ±100ppm/°C (identical)
• Number of turns: 1 (identical)
• Adjustment type: Top Adjustment (identical)
• Resistive material: Cermet (identical)
• Mounting type: Through Hole (identical)
• Termination style: PC Pins (identical)

The 3362R-1-102 maintains functional and electrical equivalence while offering active product status and improved availability.

Parameter Comparison

Engineering Selection Recommendations

The 3362R-1-102 is the manufacturer-recommended substitute for the obsolete 3366X-1-102. Both parts share identical electrical specifications and functional characteristics. The primary distinction is product status: the 3366X-1-102 is obsolete, while the 3362R-1-102 is active and maintains current manufacturing support.

Physical dimensions differ slightly between the two parts. The 3366X-1-102 features a square face (7.00mm x 7.00mm), while the 3362R-1-102 has a rectangular face (6.99mm x 6.60mm). This dimensional variance requires verification against PCB layout constraints and mechanical clearance requirements in the target application.

The 3362R-1-102 is classified as RoHS non-compliant and REACH Affected. Applications subject to RoHS or REACH compliance requirements must evaluate regulatory implications before implementation.

Frequently Asked Questions (FAQ)

Q: Can the 3362R-1-102 be used as a direct replacement for the 3366X-1-102?
