Parameter Comparison

Engineering Selection Recommendations

All three components—ERJ-S1TF3011U, CRCW25123K01FKEG, and RMCF2512FT3K01—are active production parts with full AEC-Q200 automotive certification and ROHS3 compliance. Selection among these equivalents may be based on availability and supply chain considerations. The RMCF2512FT3K01 from Stackpole Electronics currently has the highest inventory level at 6,938 units. The CRCW25123K01FKEG from Vishay Dale maintains 1,800 units in stock. The original ERJ-S1TF3011U from Panasonic has 705 units available. All parts are packaged in Tape & Reel format and carry unlimited moisture sensitivity rating, suitable for standard handling and storage protocols in automotive manufacturing environments.

Frequently Asked Questions (FAQ)

Q: Can CRCW25123K01FKEG replace ERJ-S1TF3011U directly? A: Yes. Both components share identical electrical specifications (3.01 kOhms ±1%, 1W), matching package dimensions (2512), and equivalent automotive certifications (AEC-Q200). Physical dimensions are within tolerance: CRCW25123K01FKEG measures 6.30mm x 3.15mm versus ERJ-S1TF3011U at 6.40mm x 3.20mm. Both have 0.70mm maximum seated height.

Q: What is the difference between ERJ-S1TF3011U and RMCF2512FT3K01? A: The primary difference is manufacturer. Both are 3.01 kOhms ±1% 1W thick film resistors in 2512 packages with AEC-Q200 rating. Physical dimensions are nearly identical: RMCF2512FT3K01 measures 6.30mm x 3.20mm versus ERJ-S1TF3011U at 6.40mm x 3.20mm. The ERJ-S1TF3011U includes anti-sulfur construction; this feature is not specified for the Stackpole equivalent.

Q: Are all substitutes suitable for automotive applications? A: Yes. All three parts carry AEC-Q200 automotive qualification, ROHS3 compliance, and operate across the -55°C to 155°C temperature range required for automotive environments.

Q: Does package size variation affect PCB layout? A: Dimensional variations are minimal. The maximum length difference is 0.10mm (6.40mm to 6.30mm) and width difference is 0.05mm (3.20mm to 3.15mm). All parts maintain 0.70mm maximum seated height. Standard PCB footprints for 2512 packages accommodate these tolerances without layout modification.

Q: What is the moisture sensitivity rating, and does it affect handling? A: All parts carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. Standard component handling and storage procedures apply without special desiccant or baking requirements.
