Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ERJ-S1TF1470U are qualified based on the following criteria:

Electrical Parameters: Resistance value (147 Ohms), tolerance (±1%), power rating (1W), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C ~ 155°C) must be identical.

Mechanical Parameters: Package type (2512 / 6432 Metric) and number of terminations (2) must match to ensure PCB footprint compatibility.

Compliance & Certifications: AEC-Q200 automotive qualification, ROHS3 compliance, and MSL 1 rating are required for direct substitution in automotive applications.

Composition: Thick film construction is maintained across all qualified substitutes.

The identified substitute parts meet all these criteria and are therefore electrically and mechanically interchangeable with the ERJ-S1TF1470U.

Parameter Comparison

Engineering Selection Recommendations

All three components listed—ERJ-S1TF1470U (Panasonic), AC2512FK-07147RL (YAGEO), and CRCW2512147RFKEG (Vishay Dale)—are active production parts with identical electrical and mechanical specifications. Each carries AEC-Q200 automotive qualification and ROHS3 compliance, making them suitable for direct substitution in automotive circuit applications.

Selection between these parts may be based on availability, supply chain considerations, or established vendor relationships, as all meet the same technical and compliance requirements for 147 Ohm 1W 2512 package resistor applications.

Frequently Asked Questions (FAQ)

Q: Can AC2512FK-07147RL replace ERJ-S1TF1470U in an automotive circuit?

A: Yes. Both parts share identical electrical parameters (147 Ohms ±1%, 1W, ±100ppm/°C), operate across the same temperature range (-55°C ~ 155°C), use the same 2512 package, and carry AEC-Q200 certification. They are electrically and mechanically interchangeable.

Q: Are there dimensional differences between these substitute parts?

A: Minor dimensional variations exist within the 2512 package specification. ERJ-S1TF1470U measures 0.252" L x 0.126" W (6.40mm x 3.20mm), AC2512FK-07147RL measures 0.250" L x 0.122" W (6.35mm x 3.10mm), and CRCW2512147RFKEG measures 0.248" L x 0.124" W (6.30mm x 3.15mm). These variations fall within standard 2512 package tolerances and do not affect PCB footprint compatibility.

Q: Do all substitute parts have the same moisture sensitivity rating?

A: Yes. All three parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity concerns during storage or handling.

Q: Are all substitute parts RoHS compliant?

A: Yes. ERJ-S1TF1470U, AC2512FK-07147RL, and CRCW2512147RFKEG are all ROHS3 compliant.

Q: What distinguishes the ERJ-S1TF1470U from its substitutes?

A: The ERJ-S1TF1470U includes anti-sulfur coating as an additional feature. AC2512FK-07147RL emphasizes moisture-resistant construction. CRCW2512147RFKEG provides standard automotive-grade thick film construction. All three meet core automotive requirements; feature differences reflect manufacturer design approaches rather than functional capability differences.
