ESR25JZPJ1R2 Equivalent & Substitute Parts

Part Overview

The ESR25JZPJ1R2 is a 1.2 Ohm ±5% thick film chip resistor manufactured by Rohm Semiconductor in the 1210 (3225 Metric) package. This automotive-grade component is rated for 0.667W (2/3W) power dissipation and meets AEC-Q200 qualification standards with pulse withstanding capability. The part is currently active in production with 921 pieces available in stock. Substitute parts are identified when equivalent electrical specifications, mechanical dimensions, and automotive compliance ratings are maintained across alternative manufacturers.

Substitute Part Grouping Explanation

Substitution eligibility for the ESR25JZPJ1R2 is determined by the following critical parameters:

• Resistance value: 1.2 Ohms (exact match required)
• Tolerance: ±5% (exact match required)
• Package type: 1210 (3225 Metric) (exact match required)
• Composition: Thick Film (exact match required)
• Temperature Coefficient: ±200ppm/°C (exact match required)
• Operating Temperature Range: -55°C to 155°C (exact match or better required)
• Automotive Compliance: AEC-Q200 (exact match required)
• RoHS Status: ROHS3 Compliant (exact match required)

The CRCW12101R20JNEA from Vishay Dale meets all substitution criteria with identical electrical specifications and package dimensions. The power rating difference (0.5W vs 0.667W) represents a derating condition that must be evaluated within the specific application circuit requirements.

Parameter Comparison

Engineering Selection Recommendations

Both the ESR25JZPJ1R2 and CRCW12101R20JNEA are active production components with ROHS3 compliance and AEC-Q200 automotive qualification. The primary distinction is the power rating specification: the Rohm part is rated for 0.667W while the Vishay Dale substitute is rated for 0.5W. Selection between these parts depends on the actual power dissipation requirements of the application circuit. If circuit analysis confirms power dissipation does not exceed 0.5W under worst-case operating conditions, the CRCW12101R20JNEA is a valid substitute. Both parts maintain identical electrical performance characteristics, mechanical compatibility, and environmental operating ranges.

Frequently Asked Questions (FAQ)

Q: Can CRCW12101R20JNEA replace ESR25JZPJ1R2 in all applications?

A: Substitution is valid when the application circuit power dissipation does not exceed 0.5W. The lower power rating of the Vishay Dale part requires verification against actual circuit requirements.

Q: Are the physical dimensions identical between these parts?

A: Both parts use the 1210 (3225 Metric) package with identical length and width dimensions (0.126" x 0.098" or 3.20mm x 2.50mm). The seated height differs slightly (0.026" vs 0.024"), which is within typical PCB assembly tolerances.

Q: Do both parts meet automotive qualification standards?

A: Yes, both ESR25JZPJ1R2 and CRCW12101R20JNEA carry AEC-Q200 automotive qualification and are ROHS3 compliant.

Q: What is the significance of the temperature coefficient specification?

A: Both parts specify ±200ppm/°C temperature coefficient across the -55°C to 155°C operating range, ensuring equivalent resistance stability over temperature variations in automotive environments.

Q: Are there any moisture sensitivity concerns with these parts?

A: Both parts are rated MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.
