Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ERA-2HEC4641P is determined by the following critical parameters:

• Resistance Value: 4.64 kOhms (exact match required)
• Tolerance: ±0.25% (precision specification)
• Power Rating: 0.063W minimum (1/16W)
• Package Type: 0402 (1005 Metric) form factor
• Composition: Thin film construction
• Temperature Coefficient: ±25ppm/°C
• RoHS Compliance: ROHS3 Compliant

The ERA-2AEC4641X qualifies as a direct substitute, meeting all electrical and mechanical parameters while offering extended operating temperature range (-55°C to 155°C) and automotive-grade AEC-Q200 qualification.

Parameter Comparison

Engineering Selection Recommendations

The ERA-2AEC4641X is the qualified substitute for the obsolete ERA-2HEC4641P. Both parts share identical electrical specifications (4.64 kOhms, ±0.25% tolerance, 0.063W power rating) and mechanical compatibility (0402 package, thin film construction). The ERA-2AEC4641X maintains ROHS3 compliance and MSL 1 rating, ensuring equivalent environmental performance.

The ERA-2AEC4641X offers extended operating temperature capability (-55°C to 155°C versus -55°C to 125°C) and carries AEC-Q200 automotive qualification. For applications operating within the original -55°C to 125°C range, the ERA-2AEC4641X provides direct functional equivalence with the added benefit of active product status and broader temperature margin.

Frequently Asked Questions (FAQ)

Q: Can ERA-2AEC4641X be used as a direct replacement for ERA-2HEC4641P?

A: Yes. Both parts share identical resistance (4.64 kOhms), tolerance (±0.25%), power rating (0.063W), package (0402), composition (thin film), and temperature coefficient (±25ppm/°C). The ERA-2AEC4641X is pin-compatible and electrically equivalent.

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

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

Q: Are there any package or footprint differences?

A: No. Both parts use the 0402 (1005 Metric) package with identical dimensions (0.039" L x 0.020" W / 1.00mm x 0.50mm) and maximum seated height (0.016" / 0.40mm). PCB footprints are interchangeable.

Q: Does the ERA-2AEC4641X meet RoHS requirements?

A: Yes. The ERA-2AEC4641X is ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity level, matching the environmental compliance of the original ERA-2HEC4641P.

Q: Why is ERA-2HEC4641P listed as obsolete?

A: The ERA-2H series has been superseded by the ERA-2A series, which offers automotive-grade qualification and extended temperature range while maintaining identical electrical performance for standard applications.
