Substitute Part Grouping Explanation

Substitution of the ESR10EZPJ8R2 is permissible when the following criteria are met:

• Resistance value matches exactly: 8.2 Ohms
• Tolerance specification matches: ±5%
• Package format is identical: 0805 (2012 Metric)
• Composition type is consistent: Thick Film
• Temperature coefficient remains within specification: ±200ppm/°C
• Operating temperature range covers or exceeds: -55°C ~ 155°C
• Automotive qualification is maintained: AEC-Q200
• RoHS compliance status is equivalent or superior: ROHS3 Compliant

The RPC0805JT8R20 manufactured by Stackpole Electronics Inc meets all substitution criteria. The primary difference is the power rating: the substitute part is rated at 0.25W (1/4W) compared to the original 0.4W (2/5W). This represents a lower power dissipation capability and must be evaluated against circuit requirements.

Parameter Comparison

Engineering Selection Recommendations

The RPC0805JT8R20 is a valid substitute for the ESR10EZPJ8R2 based on matching electrical specifications, identical package format, and equivalent automotive certifications. Both components maintain AEC-Q200 qualification and ROHS3 compliance.

The primary consideration for substitution is the power rating differential. The substitute part is rated at 0.25W versus the original 0.4W. Circuit design must confirm that the actual power dissipation across the 8.2 Ohm resistor does not exceed 0.25W under maximum operating conditions. The physical height difference (0.65mm versus 0.60mm) is negligible for standard PCB assembly processes.

Both components are actively produced and widely available. Selection between manufacturers should be based on supply chain requirements, lead time, and cost considerations within the constraints of the specified electrical and mechanical parameters.

Frequently Asked Questions (FAQ)

Q: Can the RPC0805JT8R20 be used as a direct replacement for the ESR10EZPJ8R2?

A: Yes, provided that the circuit power dissipation requirement does not exceed 0.25W. The substitute part meets all electrical specifications, package requirements, and automotive certifications. The lower power rating is the only limiting factor.

Q: What is the significance of the power rating difference?

A: Power rating indicates the maximum continuous power dissipation the resistor can handle without exceeding temperature limits. At 8.2 Ohms, a 0.25W rating corresponds to approximately 143mA maximum current, while 0.4W corresponds to approximately 175mA. Verify that circuit current does not exceed the substitute part's capability.

Q: Are both parts suitable for automotive applications?

A: Yes. Both the ESR10EZPJ8R2 and RPC0805JT8R20 carry AEC-Q200 automotive qualification and are designed for automotive-grade reliability. Both maintain identical operating temperature ranges and environmental compliance.

Q: Does the height difference affect PCB assembly?

A: No. The 0.01" (0.05mm) height difference is within standard PCB assembly tolerances and does not impact reflow soldering, component placement, or mechanical clearance for typical automotive applications.

Q: Are there any RoHS or environmental compliance concerns with substitution?

A: No. Both parts are ROHS3 compliant and REACH unaffected. Substitution does not introduce any environmental or regulatory compliance issues.
