Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ERA-2HEC4871P is determined by the following critical parameters:

• Resistance value: 4.87 kOhms (exact match required)
• Tolerance: ±0.25% (exact match required)
• Power rating: 0.063W minimum (1/16W)
• Package: 0402 (1005 Metric) form factor
• Composition: Thin film construction
• Temperature coefficient: ±25ppm/°C
• RoHS compliance: ROHS3 Compliant

The ERA-2AEC4871X qualifies as a direct substitute based on matching all electrical specifications and package requirements. The primary distinction is product status and operating temperature range extension.

Parameter Comparison

Engineering Selection Recommendations

The ERA-2AEC4871X is the qualified substitute for the obsolete ERA-2HEC4871P. Both parts maintain identical electrical characteristics: 4.87 kOhms resistance, ±0.25% tolerance, 0.063W power rating, and ±25ppm/°C temperature coefficient in 0402 package form factor.

The ERA-2AEC4871X offers extended operating temperature capability to 155°C compared to the 125°C maximum of the original part, with no reduction in performance within the original specification range. The substitute carries active product status with ROHS3 compliance and AEC-Q200 automotive qualification, ensuring long-term availability and supply chain stability.

Both parts are MSL 1 rated with unlimited moisture sensitivity tolerance, suitable for standard PCB assembly processes without special handling requirements.

Frequently Asked Questions (FAQ)

Q: Can ERA-2AEC4871X be used as a direct replacement for ERA-2HEC4871P?

A: Yes. Both parts share identical resistance (4.87 kOhms), tolerance (±0.25%), power rating (0.063W), package (0402), and temperature coefficient (±25ppm/°C). The substitute is electrically and mechanically interchangeable.

Q: What is the primary difference between these parts?

A: The ERA-2HEC4871P is obsolete with a -55°C to 125°C operating range. The ERA-2AEC4871X is active production with extended temperature range to 155°C and carries AEC-Q200 automotive qualification.

Q: Are there package compatibility concerns?

A: No. Both parts use identical 0402 (1005 Metric) package dimensions: 1.00mm length × 0.50mm width × 0.40mm maximum height. PCB footprints and assembly processes are identical.

Q: Does the AEC-Q200 rating on the substitute affect compatibility?

A: No. AEC-Q200 qualification represents additional quality and reliability testing. Parts meeting automotive standards are fully compatible with non-automotive applications.

Q: Are moisture sensitivity requirements different?

A: No. Both parts carry MSL 1 (Unlimited) rating, requiring no special moisture control during storage or assembly.

Q: Can the extended temperature range of ERA-2AEC4871X cause issues?

A: No. The extended range to 155°C is an enhancement. The substitute operates identically within the original -55°C to 125°C specification window.
