Key Parameters

Substitute Part Grouping Explanation

Substitution for the ERA-2HEC3571P is determined by the following critical parameters:

• Resistance Value: 4.67 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-2AEC3571X qualifies as a direct substitute because it matches all critical electrical and mechanical parameters while offering active product status and extended operating temperature range.

Parameter Comparison

Engineering Selection Recommendations

The ERA-2AEC3571X is a qualified substitute for the ERA-2HEC3571P based on the following factors:

Electrical Compatibility: Both parts share identical resistance value (4.67 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 dimensions and height specifications, ensuring PCB footprint compatibility without layout modifications.

Regulatory Compliance: Both parts are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity rating, meeting environmental and handling requirements.

Product Status Advantage: The ERA-2AEC3571X is in active production status, whereas the ERA-2HEC3571P is obsolete. This transition ensures long-term component availability and supply chain continuity.

Extended Temperature Range: The ERA-2AEC3571X supports an operating temperature range of -55°C ~ 155°C compared to -55°C ~ 125°C for the main part, providing additional thermal margin for demanding applications.

Automotive Qualification: The ERA-2AEC3571X carries AEC-Q200 automotive qualification, indicating compliance with automotive reliability standards. This certification is applicable for automotive and high-reliability applications.

Frequently Asked Questions (FAQ)

Q: Can ERA-2AEC3571X be used as a direct replacement for ERA-2HEC3571P?

A: Yes. Both parts have identical electrical specifications (4.67 kOhms ±0.25%, 0.063W), identical package dimensions (0402), and matching temperature coefficients (±25ppm/°C). Physical and electrical substitution is direct without circuit modifications.

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

A: The ERA-2A series (represented by ERA-2AEC3571X) includes AEC-Q200 automotive qualification and extended operating temperature range (-55°C ~ 155°C) compared to the ERA-2H series (-55°C ~ 125°C). Both series use identical thin film composition and tolerance specifications.

Q: Are there any PCB layout considerations when substituting ERA-2AEC3571X for ERA-2HEC3571P?

A: No. Both parts use the 0402 (1005 Metric) package with identical dimensions (0.039" L x 0.020" W) and height (0.016" max). Existing PCB footprints and layouts require no modification.

Q: Does the ERA-2AEC3571X require different handling or storage procedures?

A: No. Both parts carry identical Moisture Sensitivity Level 1 (Unlimited), indicating no special moisture control requirements during storage or handling.

Q: Is the AEC-Q200 rating on ERA-2AEC3571X relevant for non-automotive applications?

A: AEC-Q200 certification indicates compliance with automotive reliability standards but does not restrict use in non-automotive applications. The certification represents an additional quality assurance measure applicable across all application domains.
