Substitute Part Grouping Explanation

Substitution eligibility for the ERA-2HRB4641X is determined by the following critical parameters:

• Resistance Value: Must be 4.64 kOhms
• Tolerance: Must be ±0.1%
• Power Rating: Must be 0.063W (1/16W) minimum
• Package Type: Must be 0402 (1005 Metric)
• Composition: Must be Thin Film
• Temperature Coefficient: Must be ±10ppm/°C
• Operating Temperature Range: Must support minimum -55°C ~ 125°C
• RoHS Compliance: Must maintain ROHS3 Compliant status

The ERA-2ARB4641X meets all substitution criteria. This part maintains identical electrical specifications while offering enhanced product status and automotive-grade qualification.

Parameter Comparison

Engineering Selection Recommendations

The ERA-2ARB4641X is the direct substitute for the obsolete ERA-2HRB4641X. Both parts share identical electrical and mechanical specifications, ensuring drop-in compatibility at the component level.

The ERA-2ARB4641X offers additional advantages: active product status ensures long-term availability, and AEC-Q200 automotive qualification provides enhanced reliability documentation. The extended operating temperature range (-55°C ~ 155°C versus -55°C ~ 125°C) provides additional thermal margin for demanding applications.

Selection between these parts depends on application requirements and supply chain considerations. For new designs and production runs, the ERA-2ARB4641X is preferred due to active status and automotive-grade qualification. For legacy system maintenance where the original ERA-2HRB4641X specification is mandated, the ERA-2ARB4641X provides electrical and mechanical equivalence with enhanced product support.

Frequently Asked Questions (FAQ)

Q: Can ERA-2ARB4641X replace ERA-2HRB4641X in existing designs?

A: Yes. Both parts are electrically and mechanically identical. The ERA-2ARB4641X maintains the same 4.64 kOhms resistance, ±0.1% tolerance, 0.063W power rating, 0402 package, and ±10ppm/°C temperature coefficient. Physical dimensions and termination count are identical, enabling direct substitution on PCB layouts.

Q: What is the difference between ERA-2HRB and ERA-2ARB series?

A: The ERA-2ARB series incorporates automotive AEC-Q200 qualification and maintains active product status. The ERA-2HRB series is obsolete. Electrically, both series deliver identical performance for the 4.64 kOhms specification.

Q: Are there packaging differences between these parts?

A: The ERA-2HRB4641X is supplied in standard packaging. The ERA-2ARB4641X is supplied in Tape & Reel (TR) format. Both use identical 0402 (1005 Metric) component packages with matching physical dimensions and termination specifications.

Q: Does the extended temperature range of ERA-2ARB4641X affect compatibility?

A: No. The ERA-2ARB4641X operating range (-55°C ~ 155°C) encompasses the ERA-2HRB4641X range (-55°C ~ 125°C). This provides additional thermal margin without affecting electrical performance within the original specification window.

Q: Are both parts RoHS compliant?

A: Yes. Both ERA-2HRB4641X and ERA-2ARB4641X are ROHS3 Compliant with Moisture Sensitivity Level 1 (Unlimited).
