Key Parameters

Substitute Part Grouping Explanation

Substitution of the ERA-2HEC1050P is determined by strict equivalence across the following critical parameters:

• Resistance value: 105 Ohms
• Tolerance: ±0.25%
• Power rating: 0.063W (1/16W)
• Package type: 0402 (1005 Metric)
• Composition: Thin Film
• Temperature coefficient: ±25ppm/°C
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity: MSL 1

The ERA-2AEC1050X meets all these criteria and is qualified as a direct substitute. The primary distinction is that ERA-2AEC1050X carries automotive AEC-Q200 qualification and extends the operating temperature range to -55°C ~ 155°C, providing enhanced reliability for automotive applications while maintaining full compatibility with the original part's electrical specifications.

Parameter Comparison

Engineering Selection Recommendations

The ERA-2AEC1050X is the qualified substitute for the obsolete ERA-2HEC1050P. Both parts are manufactured by Panasonic Electronic Components and share identical electrical and mechanical specifications across all critical parameters: resistance value, tolerance, power rating, package type, and temperature coefficient.

The ERA-2AEC1050X offers the additional advantage of active product status, ensuring continued availability and supply chain reliability. The automotive AEC-Q200 qualification and extended operating temperature range (-55°C ~ 155°C versus -55°C ~ 125°C) provide enhanced performance margins without compromising compatibility with designs originally specified for the ERA-2HEC1050P.

Both parts maintain ROHS3 compliance and MSL 1 rating, supporting equivalent environmental and handling requirements.

Frequently Asked Questions (FAQ)

Q: Can ERA-2AEC1050X be used as a direct replacement for ERA-2HEC1050P?

A: Yes. The ERA-2AEC1050X meets all electrical and mechanical specifications of the ERA-2HEC1050P, including resistance, tolerance, power rating, package type, and temperature coefficient. The substitute is fully compatible for direct board-level substitution.

Q: What is the difference between ERA-2H and ERA-2A series?

A: The ERA-2A series incorporates automotive AEC-Q200 qualification and extends the maximum operating temperature to 155°C, compared to 125°C for the ERA-2H series. Both series maintain identical electrical characteristics and 0402 package specifications.

Q: Are there any thermal performance differences?

A: Both parts have identical power ratings (0.063W) and temperature coefficients (±25ppm/°C). The ERA-2AEC1050X supports operation at higher ambient temperatures (up to 155°C) due to automotive qualification, but thermal dissipation characteristics remain equivalent.

Q: Is the 0402 package identical between both parts?

A: Yes. Both ERA-2HEC1050P and ERA-2AEC1050X use the 0402 (1005 Metric) package with identical dimensions: 0.039" L x 0.020" W (1.00mm x 0.50mm) and maximum seated height of 0.016" (0.40mm).

Q: Do both parts have the same moisture sensitivity rating?

A: Yes. Both parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions for storage or handling.
