Substitute Part Grouping Explanation

Substitution of the ERA-2HEC3000X is based on the following critical parameters:

• Resistance value: 300 Ohms (exact match required)
• Tolerance: ±0.25% (exact match required)
• Power rating: 0.063W, 1/16W (exact match required)
• Composition: Thin Film (exact match required)
• Package: 0402 (1005 Metric) (exact match required)
• Temperature coefficient: ±25ppm/°C (exact match required)
• RoHS compliance: ROHS3 Compliant (maintained)
• Moisture sensitivity: MSL 1 (maintained)

The ERA-2AEC3000X meets all these criteria and qualifies as a direct substitute. The primary distinction is that ERA-2AEC3000X includes automotive AEC-Q200 qualification and extends the operating temperature range to -55°C ~ 155°C, providing enhanced reliability for automotive applications.

Parameter Comparison

Engineering Selection Recommendations

The ERA-2AEC3000X is the qualified substitute for the obsolete ERA-2HEC3000X. Both parts maintain identical electrical specifications (300 Ohms, ±0.25% tolerance, 0.063W power rating, ±25ppm/°C temperature coefficient) and physical package dimensions (0402 / 1005 Metric).

The ERA-2AEC3000X offers extended operating temperature capability (-55°C ~ 155°C versus -55°C ~ 125°C) and carries AEC-Q200 automotive qualification. Both parts are ROHS3 compliant with MSL 1 rating. The ERA-2AEC3000X is currently in active production status, ensuring long-term availability.

Frequently Asked Questions (FAQ)

Q: Can ERA-2AEC3000X be used as a direct replacement for ERA-2HEC3000X?

A: Yes. Both parts share identical resistance (300 Ohms), tolerance (±0.25%), power rating (0.063W), composition (thin film), package (0402), and temperature coefficient (±25ppm/°C). The ERA-2AEC3000X is electrically and mechanically compatible.

Q: What is the difference between ERA-2HEC3000X and ERA-2AEC3000X?

A: The ERA-2AEC3000X includes AEC-Q200 automotive qualification and supports an extended operating temperature range to 155°C (versus 125°C for the ERA-2HEC3000X). The ERA-2HEC3000X is obsolete; the ERA-2AEC3000X is in active production.

Q: Are the physical dimensions identical?

A: Yes. Both parts are packaged in 0402 (1005 Metric) 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: Does the extended temperature range of ERA-2AEC3000X affect circuit performance?

A: No. The temperature coefficient remains ±25ppm/°C for both parts. The extended range of ERA-2AEC3000X provides additional operational margin without affecting performance within the original ERA-2HEC3000X operating window.

Q: Are both parts RoHS compliant?

A: Yes. Both ERA-2HEC3000X and ERA-2AEC3000X are ROHS3 compliant with MSL 1 (unlimited moisture sensitivity level).
