Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following criteria:

Mandatory Compatibility Parameters:

• Resistance value: 2 kOhms (exact match required)
• Package: 1206 (3216 Metric) (exact match required)
• Composition: Thick Film (exact match required)
• Operating temperature range: -55°C to 155°C (exact match required)
• AEC-Q200 automotive rating (exact match required)
• RoHS3 compliance (exact match required)

Allowable Variation Parameters:

• Tolerance: ±5% or tighter (±1% acceptable as upgrade)
• Power rating: 0.5W or higher (0.667W and 0.75W acceptable as upgrades)
• Temperature coefficient: ±200ppm/°C or better (±100ppm/°C acceptable as upgrade)
• Manufacturer: Different manufacturers permitted if all mandatory parameters match

Identified Substitute Parts:

1. ESR18EZPF2001 (Rohm Semiconductor) – Upgrade: Tolerance improved to ±1%, temperature coefficient improved to ±100ppm/°C, power rating maintained at 0.5W
2. ERJ-P08J202V (Panasonic Electronic Components) – Upgrade: Power rating increased to 0.667W, tolerance and temperature coefficient maintained
3. RCS12062K00JNEA (Vishay Dale) – Direct equivalent: All parameters match ESR18EZPJ202
4. SR1206JR-7W2KL (YAGEO) – Direct equivalent: All parameters match ESR18EZPJ202, temperature coefficient improved to ±100ppm/°C
5. CRCW12062K00JNEAHP (Vishay Dale) – Upgrade: Power rating increased to 0.75W, all other parameters maintained

Parameter Comparison

Engineering Selection Recommendations

All identified substitute parts maintain full AEC-Q200 automotive qualification and ROHS3 compliance, ensuring regulatory and quality standards are preserved across the product family.

For direct replacement without design modification: RCS12062K00JNEA and SR1206JR-7W2KL provide electrical and mechanical equivalence to ESR18EZPJ202. Both parts are active in production with established supply availability.

For improved tolerance specification: ESR18EZPF2001 upgrades tolerance to ±1% while maintaining identical power rating and package. This substitution is applicable when circuit design requires tighter resistance accuracy.

For increased power dissipation capability: ERJ-P08J202V and CRCW12062K00JNEAHP provide power rating upgrades to 0.667W and 0.75W respectively. These upgrades are applicable when thermal analysis indicates higher power dissipation margins are required.

For multi-source strategy: The six-part family enables procurement flexibility across Rohm, Panasonic, Vishay Dale, and YAGEO manufacturers, reducing single-source dependency while maintaining identical footprint and electrical performance within specified tolerances.

Frequently Asked Questions (FAQ)

Q: Can ESR18EZPF2001 be used as a direct replacement for ESR18EZPJ202?

A: Yes. ESR18EZPF2001 is a direct substitute with improved tolerance (±1% versus ±5%) and improved temperature coefficient (±100ppm/°C versus ±200ppm/°C). The tighter tolerance represents an upgrade path with no functional degradation.

Q: What is the difference between the 0.5W, 0.667W, and 0.75W power ratings?

A: Power rating indicates maximum continuous power dissipation capability. ESR18EZPJ202 is rated 0.5W. ERJ-P08J202V (0.667W) and CRCW12062K00JNEAHP (0.75W) provide higher thermal headroom. Selection depends on circuit power dissipation requirements. Higher power ratings do not affect electrical performance in lower-power applications.

Q: Are all substitute parts in the same 1206 package?

A: Yes. All six parts use the 1206 (3216 Metric) package with identical footprint compatibility. Physical dimensions vary slightly (length 0.122" to 0.126", height 0.026" to 0.028"), but all are within standard 1206 PCB land pattern tolerances.

Q: Do all parts meet automotive AEC-Q200 requirements?

A: Yes. All identified substitute parts carry AEC-Q200 automotive qualification and are suitable for automotive applications requiring this certification.

Q: What is the significance of MSL 1 rating?

A: MSL 1 (Moisture Sensitivity Level 1) indicates unlimited shelf life without moisture bake-out requirements. All substitute parts share this rating, eliminating moisture management considerations during storage and assembly.

Q: Can I use CRCW12062K00JNEAHP in place of ESR18EZPJ202 for cost optimization?

A: Yes. CRCW12062K00JNEAHP is a direct substitute with higher power rating (0.75W) and significantly higher inventory availability (105728 units). The upgrade in power rating introduces no compatibility issues in applications designed for 0.5W operation.

Q: Are there tolerance differences that affect circuit performance?

A: ESR18EZPJ202, ERJ-P08J202V, RCS12062K00JNEA, SR1206JR-7W2KL, and CRCW12062K00JNEAHP all maintain ±5% tolerance. ESR18EZPF2001 provides ±1% tolerance. Selection depends on circuit tolerance stack-up analysis. Tighter tolerance does not degrade performance in applications designed for ±5%.
