Key Parameters

Substitute Part Grouping Explanation

Substitution of the ERA-2HEC7501P is determined by strict equivalence across the following critical parameters:

• Resistance Value: 7.5 kOhms (exact match required)
• Tolerance: ±0.25% (precision specification)
• Power Rating: 0.063W, 1/16W (thermal capability)
• Package Type: 0402 (1005 Metric) (mechanical and footprint compatibility)
• Composition: Thin Film (performance characteristics)
• Temperature Coefficient: ±25ppm/°C (stability specification)

The ERA-2AEC7501X qualifies as a direct substitute because it matches all critical electrical and mechanical parameters. The substitute is manufactured by the same supplier (Panasonic Electronic Components) and maintains identical dimensional specifications, termination count, and environmental compliance ratings.

Engineering Selection Recommendations

The ERA-2AEC7501X is a qualified substitute for the obsolete ERA-2HEC7501P. Both parts are manufactured by Panasonic Electronic Components and maintain identical electrical and mechanical specifications. The substitute offers the following advantages:

• Active Product Status: The ERA-2AEC7501X is currently in active production, ensuring long-term availability and supply chain continuity.
• Extended Operating Temperature: The substitute supports operation up to 155°C compared to 125°C for the main part, providing additional thermal margin in high-temperature applications.
• Automotive Qualification: The ERA-2AEC7501X carries AEC-Q200 certification, meeting automotive industry reliability standards. This qualification does not restrict use in non-automotive applications.
• Regulatory Compliance: Both parts maintain ROHS3 compliance and identical moisture sensitivity ratings.

Selection between these parts depends on application requirements. For applications requiring only the base specifications, either part is suitable. For automotive or high-temperature environments, the ERA-2AEC7501X is the preferred choice.

Frequently Asked Questions (FAQ)

Q: Can ERA-2AEC7501X replace ERA-2HEC7501P in existing designs?

A: Yes. The ERA-2AEC7501X is electrically and mechanically equivalent. Resistance value, tolerance, power rating, package dimensions, and termination configuration are identical. Direct substitution is possible without design modification.

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

A: The ERA-2H series represents standard thin film resistors. The ERA-2A series includes automotive-grade components with AEC-Q200 qualification. Both series share identical electrical specifications and package formats for the 7.5 kOhms ±0.25% 0402 package.

Q: Does AEC-Q200 certification affect non-automotive applications?

A: No. AEC-Q200 certification indicates the part meets automotive reliability standards. This qualification is a superset of standard requirements and does not restrict use in non-automotive applications.

Q: Are the physical dimensions identical?

A: Yes. Both parts measure 0.039" L x 0.020" W (1.00mm x 0.50mm) with maximum seated height of 0.016" (0.40mm). PCB footprints and assembly processes are identical.

Q: What is the significance of the extended temperature range in ERA-2AEC7501X?

A: The ERA-2AEC7501X operates to 155°C compared to 125°C for the ERA-2HEC7501P. This extended range provides additional thermal margin in applications approaching the upper temperature limit of the main part.

Q: Are both parts RoHS compliant?

A: Yes. Both ERA-2HEC7501P and ERA-2AEC7501X are ROHS3 compliant with moisture sensitivity level 1 (unlimited).
