ESR10EZPJ124 Equivalent & Substitute Parts

Part Overview

The ESR10EZPJ124 is a 120 kOhms ±5% thick film chip resistor manufactured by Rohm Semiconductor in 0805 (2012 Metric) package format. This component is rated for automotive applications under AEC-Q200 standard with pulse withstanding capability and 0.4W power rating. The part is currently active in production with 1025 units in stock.

Substitute parts become necessary when the original manufacturer part is unavailable, when design requirements demand higher tolerance or power ratings, or when alternative sourcing improves supply chain resilience for high-volume applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ESR10EZPJ124 is determined by the following critical parameters:

Mandatory Compatibility Parameters:

• Resistance value: 120 kOhms (exact match required)
• Package format: 0805 (2012 Metric) (exact match required)
• Composition: Thick Film (exact match required)
• Temperature Coefficient: ±200ppm/°C (exact match required)
• Operating Temperature Range: -55°C to 155°C (exact match required)
• Automotive Rating: AEC-Q200 (exact match required)

Allowable Variation Parameters:

• Tolerance: ±5% or tighter (±1% acceptable as upgrade)
• Power Rating: 0.4W or higher (0.5W acceptable as upgrade)

All substitute parts listed maintain identical electrical and mechanical specifications within these allowable parameters, ensuring direct functional equivalence in automotive applications.

Parameter Comparison

Engineering Selection Recommendations

For New Designs: ERJ-P06J124V is the preferred substitute. This part maintains active product status, identical electrical specifications, and higher power rating (0.5W vs 0.4W), providing design margin. All compliance certifications and automotive ratings are equivalent to the original ESR10EZPJ124.

For Tolerance-Critical Applications: ERJ-P6WF1203V offers ±1% tolerance compared to the ±5% specification of the main part, providing superior accuracy for precision circuits. However, this part carries "Not For New Designs" status and should be used only in legacy or existing production lines where tolerance upgrade is specifically required.

For Legacy Production Support: ERJ-P6WJ124V maintains ±5% tolerance matching the original specification and is available in production quantities (2251 units in stock). This part is designated "Not For New Designs" and should be reserved for ongoing support of existing designs.

All three substitute parts are mechanically compatible with 0805 footprints, though height variations (0.65mm to 0.75mm) should be verified against PCB assembly clearance requirements.

Frequently Asked Questions (FAQ)

Q: Can ERJ-P06J124V be used as a direct replacement for ESR10EZPJ124? A: Yes. Both parts share identical resistance (120 kOhms), tolerance (±5%), package (0805), composition (thick film), temperature coefficient (±200ppm/°C), operating range (-55°C to 155°C), and AEC-Q200 automotive rating. The ERJ-P06J124V has higher power rating (0.5W vs 0.4W), which is a compatible upgrade.

Q: What is the difference between ERJ-P6WF1203V and ERJ-P06J124V? A: The primary difference is tolerance: ERJ-P6WF1203V offers ±1% tolerance versus ±5% for ERJ-P06J124V. Both have 0.5W power rating and identical package specifications. ERJ-P6WF1203V is marked "Not For New Designs," limiting its use to legacy applications.

Q: Are there height differences between these parts? A: Yes. ESR10EZPJ124 has maximum seated height of 0.026" (0.65mm), while ERJ-P06J124V is 0.028" (0.70mm) and both Panasonic ERJ-P6W variants are 0.030" (0.75mm). Verify PCB assembly clearance specifications before substitution.

Q: Do all substitute parts meet automotive AEC-Q200 requirements? A: Yes. All listed substitute parts carry AEC-Q200 automotive rating, ROHS3 compliance, and MSL 1 moisture sensitivity level, matching the original ESR10EZPJ124 specifications.

Q: Which substitute should be selected for new production designs? A: ERJ-P06J124V is the recommended choice for new designs, as it maintains active product status while providing equivalent electrical performance and higher power rating margin.
