Key Parameters

Substitute Part Grouping Explanation

Substitution of the ERA-2HEC6981P is determined by strict equivalence across the following parameters:

• Resistance value: 6.98 kOhms
• Tolerance: ±0.25%
• Power rating: 0.063W (1/16W)
• Package: 0402 (1005 Metric)
• Composition: Thin Film
• Temperature coefficient: ±25ppm/°C
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity: MSL 1

The ERA-2AEC6981X meets all these criteria and qualifies as a direct substitute. The primary distinction is that ERA-2AEC6981X carries automotive AEC-Q200 qualification and extends the operating temperature range to -55°C ~ 155°C, making it suitable for both general industrial and automotive applications.

Parameter Comparison

Engineering Selection Recommendations

The ERA-2AEC6981X is the qualified substitute for ERA-2HEC6981P. Both parts share identical electrical specifications (6.98 kOhms, ±0.25% tolerance, 0.063W power rating) and mechanical compatibility (0402 package, thin film composition).

The ERA-2AEC6981X offers two advantages: it maintains active product status with current manufacturing support, and it includes AEC-Q200 automotive qualification. The extended operating temperature range (-55°C ~ 155°C versus -55°C ~ 125°C) provides additional thermal margin for demanding applications. Both parts maintain ROHS3 compliance and MSL 1 rating.

For applications operating within the original -55°C ~ 125°C range, the ERA-2AEC6981X provides direct functional equivalence with improved supply chain availability. For automotive or high-temperature applications, the extended temperature range and AEC-Q200 qualification of the ERA-2AEC6981X offer enhanced reliability assurance.

Frequently Asked Questions (FAQ)

Q: Can ERA-2AEC6981X replace ERA-2HEC6981P in existing designs?

A: Yes. Both parts are electrically and mechanically identical in resistance value (6.98 kOhms), tolerance (±0.25%), power rating (0.063W), package (0402), and temperature coefficient (±25ppm/°C). The ERA-2AEC6981X is a direct substitute suitable for PCB assembly without design modification.

Q: What is the difference between ERA-2HEC and ERA-2AEC series?

A: The ERA-2AEC series includes automotive AEC-Q200 qualification and extends the operating temperature range to -55°C ~ 155°C. The ERA-2HEC series operates to -55°C ~ 125°C. Both use identical thin film technology and meet ROHS3 compliance.

Q: Is the 0402 package identical between both parts?

A: Yes. Both ERA-2HEC6981P and ERA-2AEC6981X 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-2AEC6981X have any compliance or certification advantages?

A: The ERA-2AEC6981X carries AEC-Q200 automotive qualification, making it suitable for automotive and high-reliability applications. Both parts maintain ROHS3 compliance and MSL 1 rating. The ERA-2AEC6981X is the active product with current manufacturing support.

Q: Are there any thermal performance differences?

A: Both parts share identical temperature coefficient (±25ppm/°C) and power dissipation characteristics (0.063W). The ERA-2AEC6981X extends the maximum operating temperature to 155°C compared to 125°C for the ERA-2HEC6981P, providing additional thermal margin in high-temperature environments.
