ESR25JZPJ161 Equivalent & Substitute Parts

Part Overview

The ESR25JZPJ161 is a 160 Ohms ±5% thick film chip resistor rated at 0.667W (2/3W) in a 1210 (3225 Metric) package. Manufactured by Rohm Semiconductor, this component is designed for automotive applications and carries AEC-Q200 qualification with pulse withstanding capability. The part is currently in active production status with 746 units in stock.

Substitute parts are necessary when the primary component becomes unavailable, when design requirements shift toward different power ratings, or when alternative qualified suppliers are preferred for supply chain resilience.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ESR25JZPJ161 is determined by the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 160 Ohms
• Tolerance: ±5%
• Package: 1210 (3225 Metric)
• Composition: Thick Film
• Temperature Coefficient: ±200ppm/°C
• Operating Temperature Range: -55°C to 155°C
• Automotive Rating: AEC-Q200
• RoHS Compliance: ROHS3 Compliant

Allowable Variation:

• Power Rating: Substitute parts may have equal or higher power ratings. The ESR25JZPJ161 is rated at 0.667W; substitute parts rated at 0.5W (1/2W) are acceptable as they meet the same electrical performance within the specified tolerance and temperature coefficient parameters.

All substitute parts listed maintain identical resistance, tolerance, package dimensions, thermal characteristics, and automotive qualification. Differences in power rating do not affect substitution validity when the substitute rating meets or exceeds circuit requirements.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Active Status): ERJ-P14J161U and RMCF1210JT160R are both active production parts suitable for new designs. Both maintain full AEC-Q200 compliance and ROHS3 certification. Selection between these two should be based on supplier availability and procurement lead times.

Secondary Substitute (Legacy Status): ERJ-14YJ161U carries a "Not For New Designs" status and should be used only when existing inventory is available and design refresh cycles permit. This part remains electrically and mechanically equivalent but is not recommended for new product development.

Power Rating Consideration: All substitute parts are rated at 0.5W (1/2W), compared to the main part's 0.667W (2/3W) rating. This difference does not affect substitution validity. Verify that circuit power dissipation requirements do not exceed 0.5W at the resistor location before selection.

Frequently Asked Questions (FAQ)

Q: Can ERJ-P14J161U replace ESR25JZPJ161 directly? A: Yes. Both parts share identical resistance (160 Ohms), tolerance (±5%), package (1210), temperature coefficient (±200ppm/°C), operating range (-55°C to 155°C), and AEC-Q200 qualification. The lower power rating (0.5W vs 0.667W) does not prevent substitution if circuit power dissipation is within 0.5W limits.

Q: Why is ERJ-14YJ161U marked "Not For New Designs"? A: This designation indicates the part is in legacy status. While electrically and mechanically equivalent, Panasonic has discontinued active promotion of this series. It remains available from existing inventory but should not be specified for new product development.

Q: Are all substitute parts automotive qualified? A: Yes. All listed substitutes carry AEC-Q200 qualification, meeting automotive reliability and qualification standards equivalent to the main part.

Q: Do package dimensions differ between substitutes? A: No. All parts use the 1210 (3225 Metric) package with identical footprint dimensions (0.126" L x 0.098" W / 3.20mm x 2.50mm). Height variation is minimal (0.026" to 0.028" seated height), which does not affect PCB assembly compatibility.

Q: Is RoHS compliance maintained across all substitutes? A: Yes. All parts are ROHS3 compliant with MSL rating of 1 (Unlimited), matching the environmental and regulatory requirements of the main part.
