ESR25JZPJ430 Equivalent & Substitute Parts

Part Overview

The ESR25JZPJ430 is a 43 Ohm ±5% thick film chip resistor manufactured by Rohm Semiconductor in the 1210 (3225 Metric) package format. This component is rated for 0.667W (2/3W) power dissipation and meets automotive AEC-Q200 qualification standards with pulse withstanding capability. The part is currently in active production status. Substitute parts may be required due to inventory constraints, supply chain considerations, or design optimization needs while maintaining equivalent electrical and mechanical performance.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ESR25JZPJ430 are qualified based on the following criteria:

Electrical Parameters (Must Match):

• Resistance value: 43 Ohms
• Tolerance: ±5%
• Temperature coefficient: ±200ppm/°C
• Operating temperature range: -55°C ~ 155°C

Mechanical Parameters (Must Match):

• Package / Case: 1210 (3225 Metric)
• Number of terminations: 2
• Composition: Thick Film

Compliance & Ratings (Must Match):

• Automotive AEC-Q200 qualification
• RoHS3 compliance
• Moisture Sensitivity Level 1

Power Rating Consideration: Substitute parts rated at 0.5W (1/2W) are acceptable alternatives to the 0.667W (2/3W) main part, provided the application circuit design accommodates the lower power dissipation specification. The 1210 package dimensions remain identical across all qualified substitutes.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Active Status): ERJ-P14J430U (Panasonic) and RMCF1210JT43R0 (Stackpole) are both active production parts with full AEC-Q200 automotive qualification and ROHS3 compliance. Both are electrically and mechanically equivalent to the ESR25JZPJ430, with the exception of power rating (0.5W versus 0.667W). Selection between these two substitutes should be based on availability and supply chain requirements.

Legacy Substitute (Not For New Designs): ERJ-14YJ430U (Panasonic) meets all electrical and mechanical specifications but carries a "Not For New Designs" product status. This part is suitable only for replacement or repair of existing assemblies and should not be selected 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. Circuit designs must accommodate this lower power dissipation specification. The 1210 package physical dimensions are identical across all parts, with maximum seated height varying by 0.002" (0.05mm).

Frequently Asked Questions (FAQ)

Q: Can ERJ-P14J430U or RMCF1210JT43R0 be used as direct replacements for ESR25JZPJ430? A: Yes, both parts are electrically and mechanically equivalent. The primary difference is power rating: substitute parts are rated at 0.5W versus the main part's 0.667W. Circuit design must accommodate this lower power specification.

Q: What is the significance of the "Not For New Designs" status on ERJ-14YJ430U? A: This designation indicates the part is in legacy status and available only for existing product support and repairs. New product designs should select from active production alternatives: ERJ-P14J430U or RMCF1210JT43R0.

Q: Are all substitute parts AEC-Q200 qualified? A: Yes, all listed substitutes meet AEC-Q200 automotive qualification standards and are suitable for automotive applications.

Q: Do the substitute parts have identical package dimensions? A: The 1210 (3225 Metric) package footprint is identical across all parts. Maximum seated height varies slightly: ESR25JZPJ430 is 0.026" (0.65mm), while all substitutes are 0.028" (0.70mm). This 0.002" difference is within standard PCB assembly tolerances.

Q: Are all parts RoHS3 compliant? A: Yes, all listed parts are ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited).

Q: What is the temperature coefficient specification across all parts? A: All parts, including the main part and all substitutes, have a temperature coefficient of ±200ppm/°C with an operating temperature range of -55°C to 155°C.
