Key Parameters

Substitute Part Grouping Explanation

Substitution of the ERA-2HEC2870X is determined by strict equivalence across the following parameters:

• Resistance value: 287 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)
• Termination count: 2 (exact match required)
• RoHS compliance: ROHS3 (minimum requirement)

The ERA-2AEC2870X meets all substitution criteria while offering enhanced operating temperature range and automotive-grade qualification.

Parameter Comparison

Engineering Selection Recommendations

The ERA-2AEC2870X is the direct substitute for the obsolete ERA-2HEC2870X. Both components share identical electrical specifications (287 Ohms ±0.25%, 0.063W, ±25ppm/°C) and mechanical dimensions (0402 package). The ERA-2AEC2870X maintains active product status and ROHS3 compliance, ensuring long-term availability and regulatory conformance.

The ERA-2AEC2870X provides an extended operating temperature range (-55°C ~ 155°C versus -55°C ~ 125°C) and carries automotive AEC-Q200 qualification. These enhancements do not introduce incompatibility; they represent functional improvements suitable for both standard and automotive applications.

Frequently Asked Questions (FAQ)

Q: Can ERA-2AEC2870X replace ERA-2HEC2870X in existing designs?

A: Yes. The ERA-2AEC2870X is electrically and mechanically equivalent. Identical resistance (287 Ohms), tolerance (±0.25%), power rating (0.063W), package (0402), and temperature coefficient (±25ppm/°C) ensure direct substitution without circuit redesign.

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

A: The ERA-2A series incorporates automotive AEC-Q200 qualification and extended temperature range (-55°C ~ 155°C). The ERA-2H series operates to -55°C ~ 125°C. Both use identical thin film technology and meet ROHS3 requirements.

Q: Are there any package or footprint differences?

A: No. 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 (0.016" / 0.40mm). PCB footprints are interchangeable.

Q: Is the ERA-2AEC2870X suitable for automotive applications?

A: Yes. The ERA-2AEC2870X carries AEC-Q200 qualification, meeting automotive industry reliability and qualification standards. It is suitable for both automotive and general industrial applications.

Q: What is the MSL rating and does it affect handling?

A: Both components carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity. Standard handling procedures apply; no special moisture control measures are required.
