Key Parameters

Substitute Part Grouping Explanation

Substitution of the ERA-2HEC6340P is determined by strict equivalence across the following parameters:

• Resistance value: 634 Ohms (exact match required)
• Tolerance: ±0.25% (exact match required)
• Power rating: 0.063W, 1/16W (exact match required)
• Composition: Thin Film (exact match required)
• Package: 0402 (1005 Metric) (exact match required)
• Temperature coefficient: ±25ppm/°C (exact match required)
• RoHS compliance: ROHS3 Compliant (minimum requirement)
• Moisture sensitivity: MSL 1 (exact match required)

The ERA-2AEC6340X meets all substitution criteria. While the ERA-2AEC6340X features an extended operating temperature range (-55°C ~ 155°C versus -55°C ~ 125°C) and includes automotive AEC-Q200 qualification, these represent enhancements rather than deviations from the core electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

The ERA-2AEC6340X is a direct substitute for the ERA-2HEC6340P. Both components share identical electrical specifications (634 Ohms, ±0.25% tolerance, 0.063W power rating, ±25ppm/°C temperature coefficient) and mechanical compatibility (0402 package, 1.00mm × 0.50mm dimensions, 0.40mm maximum seated height).

The ERA-2AEC6340P differs in product status: the main part is obsolete while the substitute is active. The ERA-2AEC6340X incorporates automotive AEC-Q200 qualification and extends the operating temperature range to -55°C ~ 155°C, providing enhanced reliability margins for applications requiring extended temperature performance. Both components maintain ROHS3 compliance and MSL 1 rating.

Selection between these parts depends on application requirements and supply chain availability. The ERA-2AEC6340X is recommended for new designs and procurement due to its active status and automotive-grade qualification.

Frequently Asked Questions (FAQ)

Q: Can ERA-2AEC6340X replace ERA-2HEC6340P in existing designs?

A: Yes. The ERA-2AEC6340X is electrically and mechanically equivalent. Identical resistance (634 Ohms), tolerance (±0.25%), power rating (0.063W), composition (thin film), and package (0402) ensure direct substitution. The extended operating temperature range (-55°C ~ 155°C) and AEC-Q200 qualification represent performance enhancements.

Q: What is the significance of the AEC-Q200 qualification on the ERA-2AEC6340X?

A: AEC-Q200 is an automotive industry standard qualification. It indicates the component has undergone rigorous testing for automotive applications. This qualification does not affect the component's suitability for non-automotive applications.

Q: Are there dimensional differences between these parts?

A: No. Both components use the 0402 (1005 Metric) package with identical dimensions: 1.00mm length × 0.50mm width, 0.40mm maximum seated height. PCB footprints are identical.

Q: Why is the ERA-2HEC6340P listed as obsolete?

A: Product obsolescence reflects manufacturer discontinuation. The ERA-2AEC6340X, from the same manufacturer, provides equivalent functionality with active production status and enhanced specifications.

Q: Do both parts meet RoHS requirements?

A: Yes. Both ERA-2HEC6340P and ERA-2AEC6340X are ROHS3 compliant with MSL 1 (unlimited moisture sensitivity level).
