Substitute Part Grouping Explanation

Substitution of the obsolete ERA-2HEC5111P is determined by strict equivalence across the following electrical and mechanical parameters:

• Resistance value: 5.11 kOhms (exact match required)
• Tolerance: ±0.25% (exact match required)
• Power rating: 0.063W / 1/16W (exact match required)
• Package type: 0402 (1005 Metric) (exact match required)
• Composition: Thin Film (exact match required)
• Temperature coefficient: ±25ppm/°C (exact match required)
• Physical dimensions: 0.039" L x 0.020" W, height 0.016" max (exact match required)
• Termination count: 2 (exact match required)

The ERA-2AEC5111X meets all substitution criteria and is classified as an active product, providing continuity for applications previously using the ERA-2HEC5111P.

Parameter Comparison

Engineering Selection Recommendations

The ERA-2AEC5111X is the direct substitute for the obsolete ERA-2HEC5111P. Both parts are manufactured by Panasonic Electronic Components and share identical electrical specifications, tolerance, power rating, and physical package dimensions. The ERA-2AEC5111X is currently in active production status, ensuring supply chain continuity.

The ERA-2AEC5111X incorporates Automotive AEC-Q200 qualification and extends the maximum operating temperature to 155°C compared to the 125°C limit of the ERA-2HEC5111P. This enhanced temperature capability provides additional margin for applications operating at elevated temperatures. Both parts maintain ROHS3 compliance and MSL 1 rating.

Selection of the ERA-2AEC5111X eliminates obsolescence risk while maintaining full electrical and mechanical compatibility with existing designs.

Frequently Asked Questions (FAQ)

Q: Can ERA-2AEC5111X be used as a direct replacement for ERA-2HEC5111P?
