Key Parameters

Substitute Part Grouping Explanation

Substitution of the ERA-2HEC3301P is determined by strict equivalence across the following critical parameters:

• Resistance value: 3.3 kOhms
• Tolerance: ±0.25%
• Power rating: 0.063W (1/16W)
• Composition: Thin Film
• Package: 0402 (1005 Metric)
• Temperature coefficient: ±25ppm/°C
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity: MSL 1

The ERA-2AEC3301X qualifies as a direct substitute based on matching all electrical specifications, package dimensions, and environmental ratings. The primary distinction is product status and automotive qualification level.

Parameter Comparison

Engineering Selection Recommendations

The ERA-2AEC3301X is the direct substitute for the obsolete ERA-2HEC3301P. Both parts share identical electrical specifications, package geometry, and environmental compliance ratings. The ERA-2AEC3301X maintains active product status with Panasonic Electronic Components, ensuring continued availability and supply chain reliability.

The ERA-2AEC3301X carries AEC-Q200 automotive qualification, which does not restrict its use in non-automotive applications. The extended operating temperature range of -55°C to 155°C (versus -55°C to 125°C for the main part) provides additional thermal margin without introducing compatibility concerns. Both parts are ROHS3 compliant with MSL 1 rating.

Selection of the ERA-2AEC3301X eliminates obsolescence risk while maintaining full electrical and mechanical compatibility with designs originally specified for the ERA-2HEC3301P.

Frequently Asked Questions (FAQ)

Q: Can the ERA-2AEC3301X be used as a direct replacement for the ERA-2HEC3301P?

A: Yes. Both parts are electrically and mechanically identical across all critical parameters: 3.3 kOhms resistance, ±0.25% tolerance, 0.063W power rating, thin film composition, and 0402 package. The ERA-2AEC3301X is the recommended substitute due to active product status.

Q: What is the difference between the ERA-2HEC and ERA-2AEC series?

A: The ERA-2AEC series includes AEC-Q200 automotive qualification and extends the maximum operating temperature to 155°C. The ERA-2HEC series is limited to 125°C and lacks automotive certification. Both series use identical thin film technology and package specifications.

Q: Are there any compatibility issues with the 0402 package?

A: No. Both parts use the 0402 (1005 Metric) package with identical dimensions: 0.039" L × 0.020" W (1.00mm × 0.50mm) and maximum seated height of 0.016" (0.40mm). PCB footprints and assembly processes are fully compatible.

Q: Does the AEC-Q200 qualification affect non-automotive applications?

A: No. AEC-Q200 qualification represents an additional quality and reliability standard. Parts with automotive qualification are suitable for all applications, including non-automotive designs.

Q: What is the moisture sensitivity level, and does it affect handling?

A: Both parts carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. Standard component handling procedures apply without special moisture control requirements.
