ESR25JZPJ243 Equivalent & Substitute Parts

Part Overview

The ESR25JZPJ243 is a 24 kOhms ±5% thick film chip resistor manufactured by Rohm Semiconductor in the 1210 (3225 Metric) package. Rated for 0.667W (2/3W) power dissipation with automotive AEC-Q200 qualification and pulse withstanding capability, this component operates across -55°C to 155°C. The part is currently in active production status. Substitute parts may be required due to inventory constraints, supply chain disruptions, or design optimization needs while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ESR25JZPJ243 is determined by the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 24 kOhms
• Tolerance: ±5%
• Package / Case: 1210 (3225 Metric)
• Composition: Thick Film
• Operating temperature range: -55°C to 155°C
• Temperature coefficient: ±200ppm/°C
• Automotive rating: AEC-Q200
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity level: 1 (Unlimited)

Allowable Variation:

• Power rating: Substitute parts rated at 0.5W (1/2W) are acceptable as they meet or exceed the thermal requirements of circuits designed for the 0.667W (2/3W) specification when operating within the same resistance and tolerance parameters.

The identified substitute parts ERJ-P14J243U and ERJ-14YJ243U satisfy all mandatory parameters and operate within the allowable power rating variation.

Parameter Comparison

Engineering Selection Recommendations

ERJ-P14J243U (Direct Substitute): This part is the primary equivalent for the ESR25JZPJ243. Both components maintain active production status, full AEC-Q200 automotive qualification, and identical electrical specifications. The 0.5W power rating is compatible with applications designed for the 0.667W specification. This part is suitable for both new designs and replacement applications.

ERJ-14YJ243U (Upgrade Alternative): This part meets all electrical and mechanical compatibility requirements but carries a "Not For New Designs" status. It is suitable only for replacement or legacy system applications where the ESR25JZPJ243 and ERJ-P14J243U are unavailable. The identical electrical parameters and AEC-Q200 rating ensure functional compatibility in existing circuits.

Selection between these substitutes should prioritize ERJ-P14J243U for new designs due to its active production status. ERJ-14YJ243U serves as a secondary option for supply chain continuity in established applications.

Frequently Asked Questions (FAQ)

Q: Can ERJ-P14J243U replace ESR25JZPJ243 in automotive applications? A: Yes. Both parts carry AEC-Q200 automotive qualification, operate across -55°C to 155°C, and maintain identical resistance, tolerance, and temperature coefficient specifications. The 1210 package footprint is identical.

Q: What is the significance of the power rating difference (0.667W vs. 0.5W)? A: The substitute parts are rated at 0.5W, which is lower than the main part's 0.667W rating. This is acceptable when the circuit design does not require the full 0.667W dissipation capacity. If the application demands the higher power rating, the ESR25JZPJ243 should be retained.

Q: Why is ERJ-14YJ243U marked "Not For New Designs"? A: This designation indicates the manufacturer is phasing out this product line. While it remains functionally equivalent and suitable for replacement in existing applications, new designs should utilize ERJ-P14J243U or the original ESR25JZPJ243 to ensure long-term supply availability.

Q: Are all three parts mechanically interchangeable? A: Yes. All three parts use the 1210 (3225 Metric) package with identical footprint dimensions (0.126" L x 0.098" W / 3.20mm x 2.50mm). Height variations (0.026" to 0.028") are within standard PCB assembly tolerances.

Q: Do the substitute parts maintain RoHS and REACH compliance? A: Yes. Both ERJ-P14J243U and ERJ-14YJ243U are ROHS3 compliant and REACH unaffected, matching the compliance profile of the ESR25JZPJ243.

Q: Can these parts be used interchangeably in the same circuit? A: Yes, provided the circuit design does not require the full 0.667W power dissipation. All three parts share identical resistance, tolerance, temperature coefficient, and operating temperature range specifications.
