Key Parameters

Substitute Part Grouping Explanation

Substitution of the ERA-2HEC6040P is determined by strict equivalence across the following parameters:

• Resistance value: 604 Ohms (exact match required)
• Tolerance: ±0.25% (exact match required)
• Power rating: 0.063W, 1/16W (exact match required)
• Package: 0402 (1005 Metric) (exact match required)
• Composition: Thin Film (exact match required)
• Temperature coefficient: ±25ppm/°C (exact match required)
• RoHS compliance: ROHS3 Compliant (minimum requirement)
• Moisture sensitivity: MSL 1 (minimum requirement)

The ERA-2AEC6040X meets all substitution criteria while offering an extended operating temperature range and automotive-grade qualification.

Parameter Comparison

Engineering Selection Recommendations

The ERA-2AEC6040X is a direct functional equivalent to the ERA-2HEC6040P. Both components share identical electrical specifications (604 Ohms, ±0.25% tolerance, 0.063W power rating) and mechanical packaging (0402, 1005 Metric). Both maintain ROHS3 compliance and MSL 1 moisture sensitivity rating.

The ERA-2AEC6040X offers two additional advantages: active product status ensuring continued availability, and AEC-Q200 automotive qualification. The extended operating temperature range (-55°C ~ 155°C versus -55°C ~ 125°C) provides additional thermal margin for applications operating near the upper temperature limit of the original part.

Selection of the ERA-2AEC6040X is appropriate for all applications previously using the ERA-2HEC6040P, with no design modifications required.

Frequently Asked Questions (FAQ)

Q: Can ERA-2AEC6040X replace ERA-2HEC6040P in existing designs?

A: Yes. Both parts are electrically and mechanically identical across all critical parameters: 604 Ohms resistance, ±0.25% tolerance, 0.063W power rating, 0402 package, and ±25ppm/°C temperature coefficient. No circuit modifications are required.

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

A: The ERA-2A series (represented by ERA-2AEC6040X) includes AEC-Q200 automotive qualification and an extended operating temperature range to 155°C. The ERA-2H series (represented by ERA-2HEC6040P) is not automotive-qualified and operates to 125°C. Both series use identical thin film composition 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 of 0.016" (0.40mm). PCB footprints are interchangeable.

Q: Why is ERA-2HEC6040P listed as obsolete?

A: The ERA-2HEC6040P has been discontinued by Panasonic Electronic Components. The ERA-2AEC6040X represents the active replacement offering equivalent performance with enhanced specifications.

Q: Are both parts RoHS compliant?

A: Yes. Both ERA-2HEC6040P and ERA-2AEC6040X are ROHS3 compliant with MSL 1 (unlimited) moisture sensitivity rating.
