Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ERA-2HEC3571X is determined by the following critical parameters:

• Resistance Value: Must be 4.67 kOhms
• Tolerance: Must be ±0.25%
• Power Rating: Must be 0.063W (1/16W) minimum
• Package Type: Must be 0402 (1005 Metric)
• Composition: Must be Thin Film
• Temperature Coefficient: Must be ±25ppm/°C
• Termination Count: Must be 2

The ERA-2AEC3571X qualifies as a direct substitute. Both parts share identical electrical specifications, package dimensions, and thermal characteristics. The primary distinction is product status and operating temperature range extension.

Parameter Comparison

Engineering Selection Recommendations

The ERA-2AEC3571X is a qualified substitute for the obsolete ERA-2HEC3571X. Both components are manufactured by Panasonic Electronic Components and maintain identical electrical and mechanical specifications across all critical parameters.

The ERA-2AEC3571X offers the following advantages:

• Active product status ensures continued availability and supply chain reliability
• Extended operating temperature range (-55°C to 155°C versus -55°C to 125°C) provides additional thermal margin
• AEC-Q200 automotive qualification rating
• ROHS3 compliance maintained

Selection between these parts should be based on application requirements and supply availability. The ERA-2AEC3571X is recommended for new designs and ongoing production where the extended temperature range and active status provide operational benefits.

Frequently Asked Questions (FAQ)

Q: Can ERA-2AEC3571X replace ERA-2HEC3571X in existing designs?

A: Yes. Both parts share identical resistance, tolerance, power rating, package dimensions, and thermal coefficients. The ERA-2AEC3571X operates across a wider temperature range (-55°C to 155°C) and maintains the same 0402 package footprint and pin configuration.

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

A: The ERA-2H series is obsolete. The ERA-2A series is the active equivalent, featuring AEC-Q200 automotive qualification and extended operating temperature range to 155°C.

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 are interchangeable.

Q: Does the extended temperature range of ERA-2AEC3571X affect performance in standard applications?

A: No. The extended range (-55°C to 155°C) is a superset of the original specification (-55°C to 125°C). Performance within the original operating window remains identical.

Q: Are both parts RoHS compliant?

A: Yes. Both ERA-2HEC3571X and ERA-2AEC3571X are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating.
