Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC6432F224CS is determined by strict equivalence across the following parameters:

Mandatory Matching Parameters:

• Resistance value: 220 kOhms
• Tolerance: ±1%
• Power rating: 1W
• 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)

All identified substitute parts meet these mandatory parameters. Dimensional variations within the 2512 package specification are acceptable. Substitute parts are grouped by manufacturer and product status, with distinctions noted for automotive-grade qualifications (AEC-Q200) where applicable.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection (Active Status, Standard Industrial): RC2512FK-07220KL (YAGEO) is the direct equivalent substitute with Active product status and standard industrial-grade specifications. This part maintains all mandatory electrical and mechanical parameters with identical moisture-resistant thick film composition.

Alternative Selection (Active Status, Automotive Grade): CRCW2512220KFKEG (Vishay Dale) and RMCF2512FT220K (Stackpole Electronics Inc) are Active-status alternatives with AEC-Q200 automotive qualification. These parts are suitable for applications requiring automotive-grade reliability and are interchangeable from an electrical and mechanical standpoint.

Legacy Selection (Not For New Designs): ERJ-1TNF2203U (Panasonic Electronic Components) carries a "Not For New Designs" product status designation. This part meets all electrical and mechanical equivalence criteria but is not recommended for new circuit designs due to its discontinued design status.

Frequently Asked Questions (FAQ)

Q: Can RC2512FK-07220KL replace RC6432F224CS directly? A: Yes. RC2512FK-07220KL is a direct equivalent substitute. Both parts share identical electrical specifications (220 kOhms ±1%, 1W, ±100ppm/°C), operate across the same temperature range (-55°C ~ 155°C), use thick film composition, and are housed in the 2512 (6432 Metric) package. Both are ROHS3 compliant with MSL 1 rating.

Q: What is the difference between standard and automotive-grade substitutes? A: CRCW2512220KFKEG and RMCF2512FT220K carry AEC-Q200 automotive qualification, indicating enhanced reliability testing and qualification for automotive applications. The RC2512FK-07220KL does not carry this automotive designation. All three parts are electrically and mechanically equivalent for the specified parameters.

Q: Why is ERJ-1TNF2203U marked "Not For New Designs"? A: ERJ-1TNF2203U carries a "Not For New Designs" product status, indicating that Panasonic has discontinued this design line. While the part meets all electrical and mechanical equivalence criteria, it should not be selected for new circuit designs. Use RC2512FK-07220KL, CRCW2512220KFKEG, or RMCF2512FT220K instead.

Q: Are there dimensional differences between substitute parts? A: Minor dimensional variations exist within the 2512 package specification. RC6432F224CS measures 0.248" L x 0.126" W (6.30mm x 3.20mm) with 0.026" max height. RC2512FK-07220KL measures 0.250" L x 0.122" W (6.35mm x 3.10mm) with 0.026" max height. CRCW2512220KFKEG, ERJ-1TNF2203U, and RMCF2512FT220K have similar dimensional ranges within the 2512 specification. These variations are within standard package tolerances and do not affect PCB layout compatibility.

Q: Which substitute offers the best inventory availability? A: CRCW2512220KFKEG (Vishay Dale) has the highest inventory level at 25,423 pieces. RC2512FK-07220KL (YAGEO) has 5,305 pieces available. RMCF2512FT220K (Stackpole) and ERJ-1TNF2203U (Panasonic) each have approximately 12,800+ pieces in stock.

Q: Can these parts be used interchangeably in automotive applications? A: CRCW2512220KFKEG and RMCF2512FT220K carry AEC-Q200 automotive qualification and are suitable for automotive applications. RC2512FK-07220KL and RC6432F224CS do not carry automotive designation. For automotive circuit designs, select CRCW2512220KFKEG or RMCF2512FT220K.
