Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ESR18EZPJ270 is determined by the following critical parameters:

Mandatory Compatibility Criteria:

• Resistance value: 27 Ohms (exact match required)
• Package type: 1206 (3216 Metric) form factor
• Composition: Thick film construction
• Automotive compliance: AEC-Q200 rating
• Operating temperature range: -55°C to 155°C minimum
• RoHS compliance: ROHS3 Compliant

Allowable Variation Parameters:

• Tolerance: ±5% or tighter (±1% acceptable as upgrade)
• Power rating: Equal to or greater than 0.5W
• Temperature coefficient: ±200ppm/°C or better
• Moisture sensitivity: MSL 1 or equivalent

Substitute parts are classified as either direct equivalents (matching all primary specifications) or upgrades (improved tolerance or power rating while maintaining base functionality).

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts maintain active production status and full AEC-Q200 automotive compliance, ensuring continued availability and regulatory adherence for automotive applications.

ESR18EZPF27R0 (Rohm Semiconductor): This upgrade option provides improved tolerance specification (±1% versus ±5%) with identical power rating and thermal characteristics. Temperature coefficient is enhanced to ±100ppm/°C. Selection is appropriate when tighter resistance tolerance is required without increasing power dissipation requirements.

ERJ-P08J270V (Panasonic Electronic Components): This direct equivalent maintains ±5% tolerance and ±200ppm/°C temperature coefficient. Power rating is increased to 0.667W, providing additional thermal margin. Physical dimensions remain within 1206 package specification. Selection is appropriate for applications requiring higher power dissipation capability or when Panasonic component qualification is specified.

CRCW120627R0JNEAHP (Vishay Dale): This upgrade option provides the highest power rating at 0.75W while maintaining ±5% tolerance and ±200ppm/°C temperature coefficient. Physical dimensions are 0.122" L x 0.063" W (3.10mm x 1.60mm), within 1206 package tolerance. Selection is appropriate for applications with maximum thermal stress or when Vishay Dale component qualification is specified.

Frequently Asked Questions (FAQ)

Q: Can ESR18EZPF27R0 be used as a direct replacement for ESR18EZPJ270?

A: Yes. ESR18EZPF27R0 is a direct functional replacement with improved tolerance (±1% versus ±5%). All electrical parameters, package dimensions, and automotive certifications are compatible. The tighter tolerance may improve circuit performance in precision applications.

Q: What is the difference between the main part and ERJ-P08J270V?

A: Both parts are 27 Ohm ±5% resistors in 1206 package with AEC-Q200 rating. The primary difference is manufacturer (Panasonic versus Rohm) and power rating (0.667W versus 0.5W). ERJ-P08J270V provides additional thermal headroom and is suitable for higher power dissipation scenarios.

Q: Are all substitute parts suitable for automotive applications?

A: Yes. All listed parts carry AEC-Q200 automotive qualification, ROHS3 compliance, and MSL 1 moisture sensitivity rating. All are rated for -55°C to 155°C operating temperature range.

Q: Can CRCW120627R0JNEAHP be used in place of ESR18EZPJ270?

A: Yes. CRCW120627R0JNEAHP is a direct functional replacement with higher power rating (0.75W versus 0.5W). Physical dimensions are within 1206 package specification. The increased power rating provides additional design margin for thermal stress.

Q: What determines whether a part can substitute for ESR18EZPJ270?

A: Substitution requires matching resistance value (27 Ohms), tolerance equal to or better than ±5%, 1206 package form factor, thick film composition, AEC-Q200 rating, and operating temperature range of -55°C to 155°C minimum. Power rating must be equal to or greater than 0.5W.

Q: Are there any physical dimension differences between substitute parts?

A: All parts conform to 1206 (3216 Metric) package specification. Minor variations exist within tolerance: ESR18EZPJ270, ESR18EZPF27R0, and CRCW120627R0JNEAHP are 0.126" L x 0.063" W (3.20mm x 1.60mm); CRCW120627R0JNEAHP is 0.122" L x 0.063" W (3.10mm x 1.60mm). Height differences are negligible (0.026" to 0.028" maximum seated height). All variations remain within standard 1206 package tolerance and are suitable for standard PCB footprints.
