Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ERA-2HEC1502X is determined by the following critical parameters:

• Resistance Value: 15 kOhms (exact match required)
• Tolerance: ±0.25% (exact match required)
• Power Rating: 0.063W minimum (1/16W)
• Package Type: 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)
• Moisture Sensitivity: MSL 1 or better

The ERA-2AEC1502X meets all substitution criteria. It maintains identical electrical specifications (resistance, tolerance, power rating, temperature coefficient) and mechanical compatibility (0402 package, thin film construction). The substitute part operates across an extended temperature range (-55°C ~ 155°C) compared to the original specification, providing enhanced thermal performance while maintaining all other parameters.

Parameter Comparison

Engineering Selection Recommendations

The ERA-2AEC1502X is a direct functional substitute for the obsolete ERA-2HEC1502X. Both components are manufactured by Panasonic Electronic Components and share identical electrical and mechanical specifications across all critical parameters: resistance value, tolerance, power rating, package type, and temperature coefficient.

The ERA-2AEC1502X offers the following advantages:

• Active Product Status: Currently in production with confirmed inventory availability (712 Pcs), ensuring long-term supply chain reliability compared to the obsolete ERA-2HEC1502X.
• Extended Operating Temperature Range: Rated to -55°C ~ 155°C versus -55°C ~ 125°C, providing enhanced thermal margin for demanding applications.
• Automotive AEC-Q200 Qualification: Meets automotive-grade reliability standards, offering additional quality assurance beyond standard industrial specifications.
• Regulatory Compliance: ROHS3 compliant with MSL 1 rating, maintaining full environmental and moisture handling compatibility.

Direct substitution is appropriate for all applications where the ERA-2HEC1502X was originally specified, with no circuit redesign or board layout modifications required.

Frequently Asked Questions (FAQ)

Q: Can the ERA-2AEC1502X be used as a direct replacement for ERA-2HEC1502X in existing designs?

A: Yes. The ERA-2AEC1502X is electrically and mechanically identical to the ERA-2HEC1502X across all critical parameters. No circuit modifications, board layout changes, or design validation are required. The substitute part is a direct pin-for-pin and footprint-compatible replacement.

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

A: Both series are thin film chip resistors manufactured by Panasonic. The ERA-2A series includes automotive AEC-Q200 qualification, while the ERA-2H series does not. For the 15 kOhms ±0.25% 0402 package specification, all electrical and mechanical parameters are identical between the two series.

Q: Does the extended temperature range of the ERA-2AEC1502X affect compatibility?

A: No. The extended operating range (-55°C ~ 155°C versus -55°C ~ 125°C) represents an enhancement that does not impact compatibility. The substitute part operates within and exceeds the original specification range, making it suitable for applications with more demanding thermal requirements.

Q: Are there any RoHS or environmental compliance differences?

A: Both parts are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating. Environmental and regulatory compliance are equivalent between the two components.

Q: What is the inventory status for the ERA-2AEC1502X?

A: The ERA-2AEC1502X is an active product with 712 Pcs confirmed in stock as new original inventory, ensuring immediate availability for production and repair applications.

Q: Can the ERA-2AEC1502X be used in automotive applications?

A: Yes. The ERA-2AEC1502X carries AEC-Q200 automotive qualification, making it suitable for automotive-grade applications. The original ERA-2HEC1502X does not carry this certification.
