ESR25JZPJ433 Equivalent & Substitute Parts

Part Overview

The ESR25JZPJ433 is a 43 kOhms ±5% thick film chip resistor manufactured by Rohm Semiconductor in the 1210 (3225 Metric) package format. Rated for 0.667W (2/3W) power dissipation, this component meets automotive AEC-Q200 qualification standards and features pulse withstanding capability. The part is currently in active production status with 896 units available in inventory.

Substitute parts become necessary when the primary component reaches end-of-life status, experiences supply constraints, or when design requirements permit operation at reduced power ratings while maintaining electrical performance specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ESR25JZPJ433 is determined by the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 43 kOhms
• Tolerance: ±5%
• Package format: 1210 (3225 Metric)
• Composition: Thick Film
• Temperature coefficient: ±200ppm/°C
• Operating temperature range: -55°C to 155°C
• Automotive qualification: AEC-Q200
• RoHS compliance: ROHS3 Compliant

Allowable Variation:

• Power rating: Substitute parts may operate at equal or lower power ratings, provided the application does not exceed the substitute component's power dissipation limit

The ERJ-14YJ433U from Panasonic Electronic Components qualifies as a substitute based on matching all mandatory parameters. The power rating difference (0.5W versus 0.667W) represents a downrating that is acceptable for applications where the circuit design does not require the full power capability of the original component.

Parameter Comparison

Engineering Selection Recommendations

The ESR25JZPJ433 maintains active production status and represents the preferred component for new designs. This Rohm Semiconductor part provides the specified 0.667W power rating with full AEC-Q200 automotive qualification and ROHS3 compliance.

The ERJ-14YJ433U qualifies as an electrical and mechanical substitute for applications where the 0.5W power rating satisfies circuit requirements. However, this Panasonic component carries a "Not For New Designs" status designation, limiting its application to legacy system support, field replacements, or situations where supply of the primary component is unavailable.

Both components share identical electrical characteristics (43 kOhms ±5%, ±200ppm/°C temperature coefficient, -55°C to 155°C operating range) and package geometry (1210 format), ensuring direct PCB compatibility and thermal performance equivalence within their respective power ratings.

Frequently Asked Questions (FAQ)

Q: Can the ERJ-14YJ433U replace the ESR25JZPJ433 in all applications?

A: Substitution is valid only when the circuit design does not require power dissipation exceeding 0.5W. The ERJ-14YJ433U's lower power rating (0.5W versus 0.667W) represents the only functional difference. Verify that your application's maximum power dissipation remains below the substitute component's rating.

Q: Are there physical compatibility concerns between these parts?

A: Both components use the 1210 (3225 Metric) package with identical footprint dimensions (0.126" L x 0.098" W). The seated height difference (0.026" maximum for ESR25JZPJ433 versus 0.028" maximum for ERJ-14YJ433U) is negligible for standard PCB assembly and does not affect placement or clearance in typical circuit designs.

Q: Why is the ERJ-14YJ433U marked "Not For New Designs"?

A: This designation indicates that Panasonic has discontinued active development and promotion of this part number. While the component remains functionally equivalent and available in inventory (6056 units), new product designs should prioritize the ESR25JZPJ433 to ensure long-term supply continuity and manufacturer support.

Q: Do both parts meet the same automotive and compliance standards?

A: Yes. Both the ESR25JZPJ433 and ERJ-14YJ433U carry AEC-Q200 automotive qualification, ROHS3 compliance, and MSL 1 (Unlimited) moisture sensitivity rating. They are electrically and environmentally equivalent within their respective power specifications.

Q: What is the impact of the ±200ppm/°C temperature coefficient on substitution?

A: Both parts share identical temperature coefficient specifications. This parameter does not differentiate substitution eligibility. The temperature coefficient ensures predictable resistance drift across the -55°C to 155°C operating range for both components.
