Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RC6432F1331CS are qualified based on strict electrical and mechanical parameter matching. The following criteria determine substitution eligibility:

Electrical Parameters (Must Match Exactly):

• Resistance value: 1.33 kOhms
• Tolerance: ±1%
• Power rating: 1W
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C

Mechanical Parameters (Must Match Exactly):

• Package / Case: 2512 (6432 Metric)
• Number of terminations: 2
• Composition: Thick Film

Compliance Parameters (Must Match or Exceed):

• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

The identified substitute parts meet all electrical and mechanical requirements. Packaging format differences (Tape & Reel versus bulk) do not affect electrical or mechanical compatibility and represent procurement variations only.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain Active product status and ROHS3 compliance, confirming ongoing manufacturer support and regulatory alignment. The RC6432F1331CS and RMCF2512FT1K33 share identical length and width dimensions (6.30mm x 3.20mm), while the CRCW25121K33FKEG width is 3.15mm. Height differences range from 0.66mm to 0.70mm maximum seated height across all three parts.

The CRCW25121K33FKEG and RMCF2512FT1K33 both carry AEC-Q200 automotive qualification, providing additional reliability assurance for applications requiring automotive-grade components. The RC6432F1331CS features moisture-resistant construction as a primary characteristic.

All parts are available in Active status with substantial inventory: RC6432F1331CS (1038 units), CRCW25121K33FKEG (1121 units), and RMCF2512FT1K33 (1911 units). Selection between these parts should be based on packaging format requirements (Tape & Reel versus bulk), specific application certifications (AEC-Q200 for automotive use), and dimensional constraints within the specified tolerance ranges.

Frequently Asked Questions (FAQ)

Q: Can CRCW25121K33FKEG replace RC6432F1331CS in all applications?

A: Yes, from an electrical and functional standpoint. The CRCW25121K33FKEG matches all critical electrical parameters (1.33 kOhms, ±1%, 1W, ±100ppm/°C, -55°C to 155°C). The width dimension is 3.15mm versus 3.20mm on the RC6432F1331CS, a 0.05mm difference within typical PCB layout tolerances. Height difference is 0.04mm maximum. Both are ROHS3 compliant with MSL 1 rating.

Q: What is the difference between the packaging formats listed?

A: RC6432F1331CS is supplied in bulk packaging, while CRCW25121K33FKEG and RMCF2512FT1K33 are supplied in Tape & Reel (TR) format. This affects handling, storage, and automated assembly processes but does not alter electrical or mechanical performance.

Q: Are the substitute parts suitable for automotive applications?

A: CRCW25121K33FKEG and RMCF2512FT1K33 both carry AEC-Q200 automotive qualification. RC6432F1331CS does not list this certification. For automotive applications requiring AEC-Q200 compliance, use CRCW25121K33FKEG or RMCF2512FT1K33.

Q: What does Moisture Sensitivity Level 1 mean?

A: MSL 1 indicates unlimited shelf life without moisture control requirements. All three parts carry this rating, eliminating moisture-related storage constraints.

Q: Are dimensional differences significant for PCB layout?

A: The maximum dimensional variance is 0.05mm in width and 0.04mm in height. These differences are negligible for standard PCB design with typical component pad tolerances. Verify specific layout constraints if working with high-density designs or tight mechanical assemblies.

Q: Can these parts be used interchangeably in existing designs?

A: Yes, provided the design accommodates the specified dimensional ranges. All parts share the 2512 (6432 Metric) package designation and identical electrical specifications. Verify PCB footprint compatibility with the dimensional tolerances listed in the parameter comparison table.
