Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ERA-2HEC2001X is determined by the following critical parameters:

• Resistance value: 2 kOhms (exact match required)
• Tolerance: ±0.25% (exact match required)
• Power rating: 0.063W minimum (equal or higher acceptable)
• Package: 0402 (1005 Metric) (exact match required)
• Composition: Thin Film (exact match required)
• Temperature coefficient: ±25ppm/°C (exact match required)
• RoHS compliance: ROHS3 Compliant (minimum requirement)
• Moisture sensitivity: MSL 1 (exact match required)

The ERA-2AEC2001X qualifies as a direct substitute based on matching all critical electrical and mechanical parameters. The primary distinction is product status and operating temperature range extension.

Parameter Comparison

Engineering Selection Recommendations

The ERA-2AEC2001X is a qualified substitute for the obsolete ERA-2HEC2001X. Both components share identical electrical specifications (2 kOhms ±0.25%, 0.063W, ±25ppm/°C) and mechanical packaging (0402, 1005 Metric).

The ERA-2AEC2001X offers extended operating temperature capability (-55°C ~ 155°C versus -55°C ~ 125°C) and maintains active product status with current manufacturing support. The component carries Automotive AEC-Q200 qualification, indicating compliance with automotive reliability standards. Both parts maintain ROHS3 compliance and MSL 1 rating.

Selection between these parts depends on application requirements: the ERA-2AEC2001X is recommended for new designs and ongoing production due to active availability and extended temperature range. The ERA-2HEC2001X remains suitable only for legacy system maintenance where existing inventory is available.

Frequently Asked Questions (FAQ)

Q: Can ERA-2AEC2001X replace ERA-2HEC2001X in existing designs?

A: Yes. Both components share identical resistance (2 kOhms), tolerance (±0.25%), power rating (0.063W), package (0402), and temperature coefficient (±25ppm/°C). The ERA-2AEC2001X provides extended operating temperature range (-55°C ~ 155°C) and active product status.

Q: What is the primary difference between these parts?

A: The ERA-2HEC2001X is obsolete with standard specifications. The ERA-2AEC2001X is active production with Automotive AEC-Q200 qualification and extended upper operating temperature limit (155°C versus 125°C).

Q: Are the physical dimensions identical?

A: Yes. Both components are 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 meet RoHS requirements?

A: Yes. Both ERA-2HEC2001X and ERA-2AEC2001X are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating.

Q: Which part should be selected for new designs?

A: The ERA-2AEC2001X is the appropriate selection for new designs due to active product status, extended temperature range capability, and automotive qualification. The ERA-2HEC2001X should be used only for legacy system support where existing inventory exists.
