Substitute Part Grouping Explanation

Substitution eligibility for the ERJ-S1TF2700U is determined by the following criteria:

Mandatory Matching Parameters:

• Resistance value: 270 Ohms
• Tolerance: ±1%
• Package / Case: 2512 (6432 Metric)
• Composition: Thick Film
• Temperature Coefficient: ±100ppm/°C
• Operating Temperature Range: -55°C ~ 155°C
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Allowable Variation:

• Power Rating: 1W or higher (1.5W acceptable as superior specification)
• Automotive Rating: AEC-Q200 certification preferred but not mandatory for all applications
• Manufacturer: Different manufacturers acceptable if all electrical and mechanical parameters align

All four substitute parts meet the mandatory matching parameters. The CRCW2512270RFKEGHP variant offers 1.5W power rating, which exceeds the 1W requirement and is electrically compatible.

Parameter Comparison

Engineering Selection Recommendations

All four substitute parts are electrically and mechanically compatible with the ERJ-S1TF2700U based on provided specifications. Selection criteria:

For Automotive AEC-Q200 Applications: AC2512FK-07270RL, CRCW2512270RFKEGHP, and RMCF2512FT270R all carry AEC-Q200 certification. RC2512FK-07270RL does not include AEC-Q200 rating and is suitable only for non-automotive applications.

For Enhanced Power Margin: CRCW2512270RFKEGHP provides 1.5W rating versus the 1W requirement, offering additional thermal headroom in power-dissipation-critical circuits.

For Inventory Availability: RMCF2512FT270R (14,663 pieces), AC2512FK-07270RL (5,226 pieces), and RC2512FK-07270RL (8,065 pieces) offer higher stock levels than the primary part (983 pieces).

For Moisture-Resistant Applications: AC2512FK-07270RL and RC2512FK-07270RL explicitly specify moisture-resistant construction. The primary ERJ-S1TF2700U includes anti-sulfur features.

All parts maintain identical electrical performance, temperature stability, and compliance certifications where applicable.

Frequently Asked Questions (FAQ)

Q: Can CRCW2512270RFKEGHP replace ERJ-S1TF2700U in a 1W circuit? A: Yes. The 1.5W rating of CRCW2512270RFKEGHP exceeds the 1W requirement. The component operates safely at lower power levels and provides additional thermal margin.

Q: Is RC2512FK-07270RL suitable for automotive applications? A: RC2512FK-07270RL lacks AEC-Q200 certification. It is suitable for general industrial and consumer applications but not recommended for automotive designs requiring AEC-Q200 compliance.

Q: Do all substitutes fit the same PCB footprint? A: All parts use the 2512 (6432 Metric) package. Physical dimensions vary slightly within tolerance (length 6.30–6.40mm, width 3.10–3.20mm, height 0.65–0.70mm). These variations are within standard PCB design tolerances for 2512 components.

Q: What is the difference between anti-sulfur and moisture-resistant features? A: Anti-sulfur construction protects against sulfur-containing environmental contaminants. Moisture-resistant construction reduces water absorption. Both are protective features; the choice depends on the specific environmental exposure of the application.

Q: Are all substitutes RoHS3 compliant? A: Yes. All four substitute parts and the primary ERJ-S1TF2700U are ROHS3 compliant.

Q: Can these parts be used interchangeably in existing designs? A: Yes, provided the design does not mandate a specific manufacturer part number. All substitutes meet identical electrical specifications, temperature performance, and package requirements.
