Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC6432F1470CS is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 147 Ohms
• Tolerance: ±1%
• Power rating: 1W
• Package designation: 2512 (6432 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C
• Termination count: 2
• Moisture sensitivity level: 1 (Unlimited)
• RoHS compliance: ROHS3

Substitute Classification:

Upgrade Substitute: AC2512FK-07147RL (YAGEO) — Meets all electrical and mechanical parameters with additional automotive AEC-Q200 certification and moisture-resistant feature specification.

Similar Substitute: CRCW2512147RFKEG (Vishay Dale) — Meets all electrical and mechanical parameters with automotive AEC-Q200 certification.

Both substitutes maintain dimensional compatibility within tolerance and preserve all functional and compliance characteristics of the original part.

Parameter Comparison

Frequently Asked Questions (FAQ)

Q: Can AC2512FK-07147RL replace RC6432F1470CS in a standard circuit design?

A: Yes. Both parts are electrically and mechanically equivalent with identical resistance (147 Ohms), tolerance (±1%), power rating (1W), temperature coefficient (±100ppm/°C), and operating range (-55°C ~ 155°C). Dimensional variations are within acceptable PCB layout tolerances for the 2512 package.

Q: What is the difference between the three substitute options?

A: All three parts meet the core electrical specifications. AC2512FK-07147RL and CRCW2512147RFKEG both carry AEC-Q200 automotive certification, while RC6432F1470CS does not specify this certification. AC2512FK-07147RL explicitly lists moisture-resistant features. Selection depends on application requirements and supply availability.

Q: Are there packaging differences between these parts?

A: RC6432F1470CS packaging is listed as "-" (unspecified). AC2512FK-07147RL is supplied in Tape & Reel (TR) packaging. CRCW2512147RFKEG is supplied in Tape & Reel (TR) packaging. All maintain the same 2512 (6432 Metric) footprint for PCB assembly.

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

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

Q: Which part should I select for automotive applications?

A: AC2512FK-07147RL or CRCW2512147RFKEG are both qualified to AEC-Q200 automotive standards. AC2512FK-07147RL has higher inventory availability (19,022 pieces). Both are suitable for automotive electronics requiring qualified component status.

Q: Are all parts ROHS3 compliant?

A: Yes. All three parts are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: What is the temperature coefficient significance?

A: All three parts share ±100ppm/°C temperature coefficient, ensuring consistent resistance stability across the -55°C to 155°C operating range. This parameter is identical across all substitutes.
