Substitute Part Grouping Explanation

Substitute parts for the RC6432F73R2CS are identified based on strict alignment of the following critical parameters:

Electrical Parameters (Must Match Exactly):

• Resistance value: 73.2 Ohms
• Tolerance: ±1%
• Power rating: 1W
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C to 155°C

Mechanical Parameters (Must Match Exactly):

• Package format: 2512 (6432 Metric)
• Physical dimensions: 0.248" L x 0.126" W (6.30mm x 3.20mm)
• Number of terminations: 2

Compliance Parameters (Must Match or Exceed):

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

The RMCF2512FT73R2 from Stackpole Electronics Inc meets all substitution criteria with identical electrical and mechanical specifications. The substitute part includes additional automotive qualification (AEC-Q200) which does not restrict its use in non-automotive applications.

Parameter Comparison

Engineering Selection Recommendations

The RMCF2512FT73R2 is a direct electrical and mechanical equivalent to the RC6432F73R2CS. Both components are Active product status with identical compliance certifications (ROHS3, REACH Unaffected). The substitute part carries AEC-Q200 automotive qualification, which represents an additional qualification level and does not restrict application in non-automotive circuits.

The maximum seated height difference of 0.002" (0.04mm) between the two parts falls within standard PCB assembly tolerances and does not present a constraint for board-level integration. Both components feature identical electrical performance across the specified operating temperature range and maintain the same moisture sensitivity classification.

Selection between these parts should be based on supply chain availability, packaging format requirements (the substitute is supplied in Tape & Reel format), and inventory status. The RC6432F73R2CS offers 1159 pieces in current inventory, while the RMCF2512FT73R2 offers 9135 pieces in current inventory.

Frequently Asked Questions (FAQ)

Q: Can the RMCF2512FT73R2 be used as a direct replacement for the RC6432F73R2CS in all applications?

A: Yes. Both components share identical electrical specifications (73.2 Ohms ±1%, 1W, ±100ppm/°C, -55°C to 155°C), mechanical dimensions (2512 package, 0.248" x 0.126"), and compliance certifications (ROHS3, REACH Unaffected). The AEC-Q200 automotive qualification on the substitute part does not restrict its use in non-automotive applications.

Q: What is the significance of the height difference between these parts?

A: The RC6432F73R2CS has a maximum seated height of 0.026" (0.66mm), while the RMCF2512FT73R2 has a maximum seated height of 0.028" (0.70mm). This 0.002" (0.04mm) difference is within standard PCB assembly tolerances and does not affect board-level compatibility or reflow soldering processes.

Q: Are there packaging differences between these parts?

A: The RC6432F73R2CS is supplied in standard packaging format, while the RMCF2512FT73R2 is supplied in Tape & Reel (TR) format. Both packaging formats are suitable for automated assembly processes. Tape & Reel format is standard for high-volume production environments.

Q: Do the different feature sets (Moisture Resistant vs. Automotive AEC-Q200) affect substitution?

A: No. Both feature sets represent additional qualifications beyond the base thick film resistor specification. The moisture-resistant construction of the RC6432F73R2CS and the automotive qualification of the RMCF2512FT73R2 are complementary attributes that do not conflict with substitution. The substitute part meets or exceeds the environmental and compliance requirements of the original component.

Q: What compliance certifications apply to both parts?

A: Both the RC6432F73R2CS and RMCF2512FT73R2 are ROHS3 Compliant, REACH Unaffected, and classified as EAR99 for export control purposes. Both components carry HTSUS code 8533.21.0030 for tariff classification.
