Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ERA-2HEC3000P is determined by 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)
• 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)

The ERA-2AEC3000X meets all critical electrical and mechanical parameters. While the ERA-2AEC3000X features an extended operating temperature range (-55°C ~ 155°C) and includes automotive AEC-Q200 qualification, these represent enhancements rather than deviations from the base specification.

Parameter Comparison

Engineering Selection Recommendations

The ERA-2AEC3000X is a direct functional substitute for the ERA-2HEC3000P. Both components share identical electrical specifications (300 Ohms, ±0.25% tolerance, 0.063W power rating) and mechanical form factor (0402 package). The ERA-2AEC3000X is currently in active production status, whereas the ERA-2HEC3000P is obsolete.

The ERA-2AEC3000X incorporates automotive AEC-Q200 qualification and extends the maximum operating temperature to 155°C compared to the 125°C limit of the ERA-2HEC3000P. These characteristics make the ERA-2AEC3000X suitable for applications requiring enhanced reliability and extended thermal performance. Both components maintain ROHS3 compliance and identical moisture sensitivity ratings.

Frequently Asked Questions (FAQ)

Q: Can ERA-2AEC3000X replace ERA-2HEC3000P in existing designs?

A: Yes. The ERA-2AEC3000X meets all critical electrical and mechanical specifications of the ERA-2HEC3000P. Identical resistance value, tolerance, power rating, package, and temperature coefficient ensure direct functional compatibility.

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

A: The ERA-2A series (represented by ERA-2AEC3000X) includes automotive AEC-Q200 qualification and operates across an extended temperature range (-55°C ~ 155°C). The ERA-2H series (represented by ERA-2HEC3000P) operates within -55°C ~ 125°C. Both series use identical thin film composition and 0402 package specifications.

Q: Are there any compliance or certification differences?

A: Both components are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating. The ERA-2AEC3000X carries additional automotive AEC-Q200 qualification, which is not present in the ERA-2HEC3000P.

Q: Does the extended temperature range of ERA-2AEC3000X affect circuit performance?

A: No. The extended operating range of the ERA-2AEC3000X (-55°C ~ 155°C versus -55°C ~ 125°C) represents an expanded capability. Both components maintain identical temperature coefficient specifications (±25ppm/°C) within their respective operating ranges.

Q: Are the physical dimensions identical?

A: Yes. Both components 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).
