ESR25JZPJ203 Equivalent & Substitute Parts

Part Overview

The ESR25JZPJ203 is a 20 kOhms ±5% thick film chip resistor manufactured by Rohm Semiconductor in the 1210 (3225 Metric) package with 0.667W power rating. This component is rated for automotive applications under AEC-Q200 and features pulse withstanding capability. The part is currently active in production. Substitute parts may be required due to inventory availability, packaging format preferences, or specific design requirements for power dissipation and mechanical fit.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following critical parameters: resistance value (20 kOhms), tolerance (±5%), package format (1210), composition (thick film), temperature coefficient (±200ppm/°C), operating temperature range (-55°C to 155°C), and automotive AEC-Q200 compliance. All substitute parts listed maintain these core electrical and mechanical specifications. Power rating variations are noted where they differ from the main part, as lower power ratings represent design downgrades that may be acceptable depending on circuit requirements. Packaging format (Tape & Reel versus Cut Tape) does not affect electrical equivalence but impacts procurement and assembly processes.

Parameter Comparison

Engineering Selection Recommendations

ERJ-P14J203U and CRCW121020K0JNEA are direct electrical equivalents suitable for new designs. Both maintain full AEC-Q200 automotive compliance and ROHS3 certification. The primary distinction is packaging format: ERJ-P14J203U is supplied in Cut Tape format, while CRCW121020K0JNEA is supplied in Tape & Reel format matching the original part's packaging. Both substitute parts have reduced power ratings (0.5W versus 0.667W); this represents a design downgrade and is acceptable only if circuit power dissipation does not exceed 0.5W at maximum operating conditions.

ERJ-14YJ203U carries a "Not For New Designs" status and should be avoided for new product development. This part is electrically equivalent but is in end-of-life phase and not recommended for designs requiring long-term component availability.

Frequently Asked Questions (FAQ)

Q: Can ERJ-P14J203U replace ESR25JZPJ203 in all applications? A: ERJ-P14J203U is electrically equivalent with identical resistance, tolerance, temperature coefficient, and automotive rating. The reduced power rating (0.5W versus 0.667W) requires verification that circuit power dissipation remains below 0.5W. Packaging format differs (Cut Tape versus Tape & Reel), which may affect assembly line compatibility.

Q: What is the significance of the power rating difference? A: The ESR25JZPJ203 is rated for 0.667W continuous dissipation, while substitute parts are rated for 0.5W. If the circuit design requires power dissipation above 0.5W, the substitute parts are not suitable. If dissipation remains below 0.5W, the lower rating does not affect functionality.

Q: Why is ERJ-14YJ203U marked "Not For New Designs"? A: This designation indicates the part is in end-of-life status. While electrically equivalent, it should not be selected for new product development due to uncertain long-term availability and potential supply discontinuation.

Q: Are all substitute parts AEC-Q200 compliant? A: Yes. All listed substitute parts maintain AEC-Q200 automotive qualification, ROHS3 compliance, and MSL 1 moisture sensitivity rating, ensuring compatibility with automotive applications.

Q: Does packaging format affect electrical performance? A: No. Tape & Reel and Cut Tape formats are procurement and assembly considerations only. Electrical performance is identical. Selection depends on assembly equipment compatibility and inventory management requirements.
