Key Parameters

Substitute Part Grouping Explanation

Substitution for the ERA-2HEC7871P is determined by the following critical parameters:

• Resistance Value: 7.87 kOhms (exact match required)
• Tolerance: ±0.25% (precision specification)
• Power Rating: 0.063W, 1/16W (electrical stress rating)
• Package Type: 0402 (1005 Metric) (physical and footprint compatibility)
• Composition: Thin Film (performance characteristics)
• Temperature Coefficient: ±25ppm/°C (thermal stability)
• RoHS Compliance: ROHS3 Compliant (regulatory requirement)

The ERA-2AEC7871X qualifies as a direct substitute because it matches all critical electrical and mechanical parameters while offering enhanced product status and extended operating temperature range.

Parameter Comparison

Engineering Selection Recommendations

The ERA-2AEC7871X is the qualified substitute for the obsolete ERA-2HEC7871P. Both parts are manufactured by Panasonic Electronic Components and share identical electrical specifications and physical dimensions. The ERA-2AEC7871X offers the following advantages:

• Active Product Status: Currently in production with confirmed inventory availability (912 Pcs)
• Extended Operating Temperature Range: -55°C ~ 155°C versus -55°C ~ 125°C, providing additional thermal margin
• Automotive AEC-Q200 Qualification: Meets automotive reliability standards
• Regulatory Compliance: ROHS3 Compliant with REACH Unaffected status

The ERA-2AEC7871X maintains full electrical and mechanical compatibility with the original ERA-2HEC7871P, requiring no circuit redesign or PCB layout modifications.

Frequently Asked Questions (FAQ)

Q: Can ERA-2AEC7871X be used as a direct replacement for ERA-2HEC7871P?

A: Yes. Both parts have identical resistance (7.87 kOhms), tolerance (±0.25%), power rating (0.063W), package (0402), and temperature coefficient (±25ppm/°C). The ERA-2AEC7871X is footprint-compatible and electrically equivalent.

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

A: The ERA-2A series includes automotive AEC-Q200 qualification and extended operating temperature range (-55°C ~ 155°C) compared to the ERA-2H series (-55°C ~ 125°C). Both series use identical thin film composition and precision tolerance specifications.

Q: Are there any PCB layout considerations when substituting ERA-2AEC7871X for ERA-2HEC7871P?

A: No. Both parts use the same 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). No PCB modifications are required.

Q: Is the ERA-2AEC7871X suitable for automotive applications?

A: Yes. The ERA-2AEC7871X carries AEC-Q200 automotive qualification, making it suitable for automotive-grade applications. The ERA-2HEC7871P does not have this certification.

Q: What is the moisture sensitivity level for both parts?

A: Both ERA-2HEC7871P and ERA-2AEC7871X have MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.
