Key Parameters

Substitute Part Grouping Explanation

Substitution of the ERA-2HEC9760P is determined by strict equivalence across the following parameters:

• Resistance value: 976 Ohms (exact match required)
• Tolerance: ±0.25% (precision specification)
• Power rating: 0.063W, 1/16W (electrical stress limit)
• Composition: Thin Film (performance characteristics)
• Package: 0402 (1005 Metric) (physical and thermal compatibility)
• Temperature coefficient: ±25ppm/°C (frequency stability)
• RoHS compliance: ROHS3 Compliant (regulatory requirement)

The ERA-2AEC9760X meets all these criteria while offering enhanced operating temperature range and automotive qualification, making it a direct functional equivalent.

Parameter Comparison

Engineering Selection Recommendations

The ERA-2AEC9760X is the direct substitute for the obsolete ERA-2HEC9760P. Both components share identical electrical specifications (976 Ohms, ±0.25% tolerance, 0.063W power rating, ±25ppm/°C temperature coefficient) and physical package (0402 1005 Metric). Both maintain ROHS3 compliance and MSL 1 rating.

The ERA-2AEC9760X offers two additional advantages: active product status ensuring continued availability, and automotive AEC-Q200 qualification with extended operating temperature range (-55°C ~ 155°C versus -55°C ~ 125°C). These enhancements provide superior reliability margins without compromising the original design specifications.

Selection of the ERA-2AEC9760X eliminates obsolescence risk while maintaining full electrical and mechanical compatibility with the original ERA-2HEC9760P design.

Frequently Asked Questions (FAQ)

Q: Can ERA-2AEC9760X replace ERA-2HEC9760P in existing designs?

A: Yes. Both components have identical resistance (976 Ohms), tolerance (±0.25%), power rating (0.063W), composition (thin film), package (0402), and temperature coefficient (±25ppm/°C). Physical dimensions and termination count are identical. Direct substitution is electrically and mechanically compatible.

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

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

Q: Does the extended temperature range of ERA-2AEC9760X affect circuit performance?

A: No. The extended range (-55°C ~ 155°C) represents an expanded operational envelope. The temperature coefficient (±25ppm/°C) remains identical, ensuring equivalent frequency stability and performance characteristics across the overlapping temperature range.

Q: Are there inventory considerations for this substitution?

A: The ERA-2HEC9760P is obsolete with 873 pieces in stock. The ERA-2AEC9760X is active production with 801 pieces available. Long-term procurement should prioritize the ERA-2AEC9760X to ensure supply continuity.

Q: Is the 0402 package footprint identical between both parts?

A: Yes. Both components 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 layout and assembly processes require no modification.
