Key Parameters

Substitute Part Grouping Explanation

Substitution for the ERA-2HEC1582P is determined by the following critical parameters:

• Resistance Value: 15.8 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-2AEC1582X qualifies as a direct substitute because it matches all critical electrical and mechanical parameters while offering active product status and automotive-grade qualification (AEC-Q200).

Parameter Comparison

Engineering Selection Recommendations

The ERA-2AEC1582X is a qualified substitute for the ERA-2HEC1582P based on the following factors:

Electrical Compatibility: Both parts share identical resistance value (15.8 kOhms), tolerance (±0.25%), power rating (0.063W), and temperature coefficient (±25ppm/°C). These parameters ensure functional equivalence in circuit applications.

Physical Compatibility: Both parts use the 0402 (1005 Metric) package with identical footprint dimensions (0.039" L x 0.020" W, 1.00mm x 0.50mm) and maximum seated height (0.016", 0.40mm), enabling direct PCB layout compatibility.

Regulatory Compliance: Both parts meet ROHS3 compliance and maintain MSL 1 (Unlimited) moisture sensitivity rating, satisfying environmental and handling requirements.

Product Availability: The ERA-2AEC1582X holds active product status with 1136 pieces in stock, compared to the obsolete ERA-2HEC1582P with 988 pieces. This ensures long-term supply continuity.

Enhanced Operating Range: The ERA-2AEC1582X extends the maximum operating temperature to 155°C (versus 125°C for the main part) and includes AEC-Q200 automotive qualification, providing additional design margin for temperature-sensitive applications.

Frequently Asked Questions (FAQ)

Q: Can ERA-2AEC1582X be used as a direct replacement for ERA-2HEC1582P?

A: Yes. Both parts are 15.8 kOhms ±0.25% thin film resistors in 0402 package with identical electrical specifications and footprint dimensions. The ERA-2AEC1582X is electrically and mechanically compatible.

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

A: The ERA-2H series (main part) is a standard thin film resistor line. The ERA-2A series (substitute) is an automotive-grade variant with AEC-Q200 qualification and extended operating temperature range (-55°C to 155°C versus -55°C to 125°C). Both series share the same electrical performance and package specifications.

Q: Does the extended temperature range of ERA-2AEC1582X affect circuit performance?

A: No. The extended operating temperature range of the ERA-2AEC1582X does not degrade performance within the original design temperature limits. The temperature coefficient (±25ppm/°C) remains identical, ensuring equivalent thermal stability.

Q: Are there any handling or storage differences between these parts?

A: No. Both parts maintain MSL 1 (Unlimited) moisture sensitivity level and ROHS3 compliance. Handling, storage, and soldering procedures are identical.

Q: Why is the ERA-2HEC1582P marked as obsolete?

A: The ERA-2HEC1582P is classified as obsolete by the manufacturer. The ERA-2AEC1582X represents the active product line continuation with equivalent electrical performance and enhanced automotive qualification.
