Substitute Part Grouping Explanation

Substitution of the ERA-2HEC6341P is determined by the following critical parameters:

• Resistance Value: Must be 6.34 kOhms
• Tolerance: Must be ±0.25%
• Power Rating: Must be 0.063W (1/16W) minimum
• Package: Must be 0402 (1005 Metric)
• Composition: Must be Thin Film
• Temperature Coefficient: Must be ±25ppm/°C
• Physical Dimensions: Must match 0.039" L x 0.020" W (1.00mm x 0.50mm) with maximum seated height of 0.016" (0.40mm)
• Terminations: Must have 2 terminations
• Compliance: Must maintain ROHS3 compliance and MSL 1 rating

The ERA-2AEC6341X qualifies as a direct substitute based on matching all electrical and mechanical parameters while offering extended operating temperature range and automotive-grade qualification.

Engineering Selection Recommendations

The ERA-2AEC6341X is a direct functional equivalent to the ERA-2HEC6341P. Both parts share identical electrical specifications, physical dimensions, and package configuration. The ERA-2AEC6341X offers the following advantages:

• Active Product Status: The substitute is currently in active production, ensuring long-term availability and supply chain stability.
• Extended Temperature Range: Operating temperature extends to 155°C compared to 125°C, providing additional thermal margin in high-temperature applications.
• Automotive Qualification: AEC-Q200 certification qualifies the substitute for automotive applications where applicable.
• Regulatory Compliance: Both parts maintain ROHS3 compliance and identical moisture sensitivity ratings.

Selection of the ERA-2AEC6341X eliminates obsolescence risk while maintaining full electrical and mechanical compatibility with designs originally specified for the ERA-2HEC6341P.

Frequently Asked Questions (FAQ)

Q: Can ERA-2AEC6341X be used as a direct replacement for ERA-2HEC6341P?

A: Yes. Both parts have identical resistance value (6.34 kOhms), tolerance (±0.25%), power rating (0.063W), package (0402), composition (thin film), temperature coefficient (±25ppm/°C), physical dimensions, and termination count. The substitute is electrically and mechanically interchangeable.

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

A: The ERA-2A series includes automotive-grade AEC-Q200 qualification and extends the maximum operating temperature to 155°C. The ERA-2H series is standard industrial grade with a maximum operating temperature of 125°C. Both series use identical thin film technology and package configurations.

Q: Does the extended temperature range of ERA-2AEC6341X affect circuit performance?

A: No. The extended temperature range represents an expanded operating envelope. The temperature coefficient (±25ppm/°C) remains identical, ensuring equivalent frequency stability and resistance drift characteristics across the overlapping temperature range (-55°C to 125°C).

Q: Are there any PCB layout or assembly considerations when substituting ERA-2AEC6341X for ERA-2HEC6341P?

A: No. Both parts use the same 0402 (1005 Metric) package with identical footprint dimensions (0.039" L x 0.020" W) and maximum seated height (0.016"). No PCB redesign or assembly process changes are required.

Q: What is the moisture sensitivity level for both parts?

A: Both ERA-2HEC6341P and ERA-2AEC6341X have MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions. Standard handling and storage practices apply.

Q: Are both parts RoHS compliant?

A: Yes. Both ERA-2HEC6341P and ERA-2AEC6341X are ROHS3 compliant, meeting all applicable environmental and hazardous substance restrictions.
