Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RC6432F4220CS are qualified based on strict equivalence across the following criteria:

Electrical Parameters: Resistance value (422 Ohms), tolerance (±1%), power rating (1W), composition (thick film), and temperature coefficient (±100ppm/°C) must be identical.

Mechanical Parameters: Package designation (2512 / 6432 Metric) and termination count (2) must match. Physical dimensions must fall within acceptable tolerances for PCB footprint compatibility.

Environmental & Compliance: Operating temperature range (-55°C to 155°C), RoHS3 compliance, MSL 1 rating, and REACH unaffected status must be maintained.

Packaging Format: Tape & Reel (TR) packaging is standard for substitute parts, enabling automated assembly compatibility.

Three substitute parts meet these criteria: CRCW2512422RFKEG (Vishay Dale), ERJ-1TNF4220U (Panasonic Electronic Components), and RMCF2512FT422R (Stackpole Electronics Inc).

Parameter Comparison

Engineering Selection Recommendations

For Active Production Designs: CRCW2512422RFKEG (Vishay Dale) and RMCF2512FT422R (Stackpole Electronics Inc) are both active production parts with full compliance certifications. Both incorporate automotive AEC-Q200 qualification, providing enhanced reliability margins. CRCW2512422RFKEG offers 4748 units in stock; RMCF2512FT422R provides 5578 units in stock.

For Legacy or Existing Designs: ERJ-1TNF4220U (Panasonic Electronic Components) is marked "Not For New Designs" but remains electrically and mechanically equivalent. This part carries AEC-Q200 automotive qualification and maintains all compliance requirements. Use is restricted to design continuation or field replacement scenarios only. Inventory availability is 5520 units.

Compliance Consideration: All three substitute parts maintain ROHS3 compliance, MSL 1 rating, and REACH unaffected status, matching the original RC6432F4220CS specifications exactly.

Frequently Asked Questions (FAQ)

Q: Can CRCW2512422RFKEG directly replace RC6432F4220CS on existing PCBs?

A: Yes. Both components share identical electrical specifications (422 Ohms ±1%, 1W, ±100ppm/°C), operate across -55°C to 155°C, and use the 2512 (6432 Metric) package. Physical dimensions are within acceptable tolerance for PCB footprint compatibility (Vishay: 6.30mm L × 3.15mm W vs. Samsung: 6.30mm L × 3.20mm W).

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

A: All three meet electrical and mechanical equivalence criteria. Primary differences are manufacturer (Vishay Dale, Panasonic, Stackpole), product status (Vishay and Stackpole are active; Panasonic is not for new designs), and minor physical dimension variations within acceptable tolerances. All carry AEC-Q200 automotive qualification.

Q: Why is ERJ-1TNF4220U marked "Not For New Designs"?

A: This designation indicates Panasonic has discontinued this part for new design applications. However, the component remains electrically and mechanically equivalent and is suitable for field replacement or design continuation. New designs should prioritize CRCW2512422RFKEG or RMCF2512FT422R.

Q: Are all substitute parts available in Tape & Reel packaging?

A: Yes. All three substitute parts are supplied in Tape & Reel (TR) format, enabling compatibility with automated assembly equipment.

Q: Do all parts maintain the same moisture sensitivity level?

A: Yes. RC6432F4220CS and all three substitute parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions during storage or handling.

Q: Are there any temperature coefficient differences between the main part and substitutes?

A: No. All parts, including the main component and all three substitutes, maintain ±100ppm/°C temperature coefficient across the -55°C to 155°C operating range.
