ESR18EZPJ114 Equivalent & Substitute Parts

Part Overview

The ESR18EZPJ114 is a 110 kOhms ±5% thick film chip resistor in 1206 (3216 Metric) package rated for 0.5W power dissipation. Manufactured by Rohm Semiconductor, this component is designed for automotive applications and meets AEC-Q200 qualification standards with pulse withstanding capability. The part is currently in active production status with 1146 units available in inventory. Equivalent and substitute parts may be required due to supply chain constraints, design optimization for higher power ratings, or procurement preferences for alternative manufacturers while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the ESR18EZPJ114 is determined by strict equivalence in the following critical parameters:

• Resistance value: 110 kOhms (exact match required)
• Tolerance: ±5% (exact match required)
• Package / Case: 1206 (3216 Metric) (exact match required)
• Composition: Thick Film (exact match required)
• Temperature Coefficient: ±200ppm/°C (exact match required)
• Operating Temperature Range: -55°C ~ 155°C (exact match required)
• Automotive Rating: AEC-Q200 (exact match required)
• RoHS Compliance: ROHS3 Compliant (exact match required)

The ERJ-P08J114V from Panasonic Electronic Components meets all substitution criteria. While the power rating differs (0.667W versus 0.5W), this represents a higher capability that maintains full compatibility in applications designed for the original 0.5W specification. The identical package dimensions, electrical characteristics, and automotive qualifications ensure direct functional equivalence.

Parameter Comparison

Engineering Selection Recommendations

Both the ESR18EZPJ114 and ERJ-P08J114V are active production components with full AEC-Q200 automotive qualification and ROHS3 compliance. Selection between these parts should be based on:

Availability and lead time requirements. The ERJ-P08J114V currently has higher inventory (5827 units) compared to the ESR18EZPJ114 (1146 units).

Power dissipation margin. The ERJ-P08J114V provides 33% higher power rating (0.667W versus 0.5W), offering additional thermal headroom in applications where power dissipation approaches the component limit.

Mechanical clearance. The ERJ-P08J114V has a maximum seated height of 0.028" (0.70mm) compared to 0.026" (0.65mm) for the ESR18EZPJ114. Verify PCB layout constraints if height tolerance is critical.

Manufacturer preference and supply chain strategy. Both components are from established manufacturers with equivalent reliability and compliance certifications.

Frequently Asked Questions (FAQ)

Q: Can ERJ-P08J114V be used as a direct replacement for ESR18EZPJ114 in existing designs?

A: Yes. The ERJ-P08J114V meets all electrical and mechanical specifications required for direct substitution. The higher power rating (0.667W versus 0.5W) provides additional capability without affecting circuit performance. Verify PCB layout accommodates the maximum seated height of 0.028" (0.70mm).

Q: What is the significance of the power rating difference between these parts?

A: The ESR18EZPJ114 is rated for 0.5W dissipation, while the ERJ-P08J114V is rated for 0.667W. In applications where the original design operates below 0.5W, the substitute part provides additional thermal margin. No circuit redesign is required.

Q: Are both parts suitable for automotive applications?

A: Yes. Both the ESR18EZPJ114 and ERJ-P08J114V carry AEC-Q200 automotive qualification and are designed for operating temperatures from -55°C to 155°C. Both are ROHS3 compliant and REACH unaffected.

Q: What packaging format is used for these components?

A: Both parts are supplied in Tape & Reel (TR) format in 1206 (3216 Metric) package. The physical dimensions are identical at 0.126" L x 0.063" W (3.20mm x 1.60mm), with maximum seated heights of 0.026" and 0.028" respectively.

Q: Do these parts have any moisture sensitivity concerns?

A: No. Both components are rated MSL 1 (Unlimited), indicating no moisture sensitivity limitations for storage, handling, or reflow processing.
