Key Parameters

Substitute Part Grouping Explanation

Substitution for the ERA-2HEC1152P is determined by the following critical parameters:

• Resistance Value: 11.5 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-2AEC1152X 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-2AEC1152X is the qualified substitute for ERA-2HEC1152P based on the following factors:

Electrical Compatibility: Both parts share identical resistance value (11.5 kOhms), tolerance (±0.25%), power rating (0.063W), and temperature coefficient (±25ppm/°C). These parameters ensure functional equivalence in circuit applications.

Package Compatibility: Both parts use the 0402 (1005 Metric) package with identical physical dimensions and termination configuration, enabling direct PCB footprint compatibility without layout modifications.

Regulatory Compliance: Both parts meet ROHS3 compliance requirements and share MSL 1 rating, satisfying environmental and handling standards.

Product Status Advantage: The ERA-2AEC1152X is active production status, ensuring long-term availability and supply chain reliability compared to the obsolete ERA-2HEC1152P.

Extended Temperature Range: The ERA-2AEC1152X supports -55°C ~ 155°C operating range, exceeding the ERA-2HEC1152P specification (-55°C ~ 125°C), providing additional thermal margin for demanding applications.

Automotive Qualification: The ERA-2AEC1152X carries AEC-Q200 automotive qualification, indicating enhanced reliability testing and quality assurance suitable for automotive and high-reliability applications.

Frequently Asked Questions (FAQ)

Q: Can ERA-2AEC1152X be used as a direct replacement for ERA-2HEC1152P?

A: Yes. Both parts share identical electrical specifications (11.5 kOhms ±0.25%, 0.063W, ±25ppm/°C) and package configuration (0402 1005 Metric). The ERA-2AEC1152X is a direct functional and physical substitute.

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

A: The ERA-2H series (obsolete) and ERA-2A series (active) are both Panasonic thin film chip resistor lines. The ERA-2A series includes automotive-grade variants with AEC-Q200 qualification and extended temperature range support (-55°C ~ 155°C vs. -55°C ~ 125°C).

Q: Are there any PCB layout changes required when substituting ERA-2AEC1152X for ERA-2HEC1152P?

A: No. Both parts use identical 0402 (1005 Metric) package dimensions and footprint specifications. No PCB layout modifications are necessary.

Q: Does the extended operating temperature range of ERA-2AEC1152X affect circuit performance?

A: The extended range (-55°C ~ 155°C) of ERA-2AEC1152X provides additional thermal margin but does not negatively affect performance. Both parts maintain identical temperature coefficient (±25ppm/°C) and tolerance specifications across their respective operating ranges.

Q: Is RoHS compliance maintained with the substitute part?

A: Yes. Both ERA-2HEC1152P and ERA-2AEC1152X are ROHS3 compliant, maintaining regulatory compliance in the substitution.

Q: What is the inventory status for these parts?

A: ERA-2HEC1152P (obsolete): 1079 Pcs available. ERA-2AEC1152X (active): 1154 Pcs available. The active status of ERA-2AEC1152X ensures continued availability for future procurement.
