ESR10EZPJ821 Equivalent & Substitute Parts

Part Overview

The ESR10EZPJ821 is a 820 Ohms ±5% 0.4W thick film chip resistor in 0805 (2012 Metric) package manufactured by Rohm Semiconductor. This component is rated for automotive applications under AEC-Q200 standard with pulse withstanding capability. The part is currently in active production status. Substitute parts are necessary when the original manufacturer part becomes unavailable, when inventory constraints require alternative sourcing, or when design requirements permit higher power ratings or improved tolerance specifications.

Engineering Selection Recommendations

Recommended Direct Substitutes (Active Status):

ERJ-P06J821V and CRCW0805820RJNEAHP are the primary substitutes for new designs. Both parts maintain active production status, identical electrical specifications, and full AEC-Q200 automotive qualification. ERJ-P06J821V offers higher inventory availability (13,778 units), while CRCW0805820RJNEAHP provides the lowest profile height at 0.020" (0.50mm), which may be advantageous for space-constrained applications.

ERJ-UP6J821V is an alternative active substitute with anti-sulfur feature enhancement, suitable for environments with corrosive atmospheric conditions.

Legacy Substitutes (Not For New Designs):

ERJ-P6WF8200V and ERJ-P6WJ821V are available but designated as "Not For New Designs" by the manufacturer. These parts should only be used for replacement or repair of existing assemblies where design continuity is required. ERJ-P6WF8200V offers improved ±1% tolerance specification if tighter tolerance is required for legacy systems.

Height Considerations:

Physical height variation ranges from 0.020" to 0.030" across substitute options. Verify PCB assembly clearance requirements before selection, particularly in applications with height-constrained layouts.

Frequently Asked Questions (FAQ)

Q: Can ERJ-P06J821V directly replace ESR10EZPJ821 in existing designs?

A: Yes. ERJ-P06J821V is electrically and mechanically compatible. Both parts share identical resistance (820 Ohms), tolerance (±5%), package (0805), temperature coefficient (±200ppm/°C), operating temperature range (-55°C to 155°C), and AEC-Q200 automotive qualification. The higher power rating (0.5W vs 0.4W) and slightly increased height (0.028" vs 0.026") present no functional incompatibility.

Q: What is the difference between ERJ-P06J821V and ERJ-UP6J821V?

A: Both parts are electrically identical with 820 Ohms ±5% at 0.5W in 0805 package. ERJ-UP6J821V includes anti-sulfur feature for enhanced corrosion resistance in harsh environments. Selection depends on environmental exposure requirements.

Q: Why is CRCW0805820RJNEAHP listed as an upgrade?

A: CRCW0805820RJNEAHP provides the lowest profile height (0.020" vs 0.026" original), enabling use in space-constrained PCB layouts while maintaining all electrical and compliance specifications.

Q: Can ERJ-P6WF8200V be used in new designs?

A: No. This part is designated "Not For New Designs" by Panasonic. It is available only for replacement of existing assemblies. For new designs, select from active-status alternatives: ERJ-P06J821V, CRCW0805820RJNEAHP, or ERJ-UP6J821V.

Q: Are all substitutes RoHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance and are REACH unaffected, matching the original ESR10EZPJ821 environmental compliance status.

Q: Does tolerance difference affect substitutability?

A: ERJ-P6WF8200V offers ±1% tolerance versus the original ±5%. Tighter tolerance is acceptable as a substitute and may improve circuit performance in precision applications. However, verify that circuit design does not depend on the original ±5% tolerance specification before substitution.
