Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC6432F7680CS is determined by strict alignment of the following critical parameters:

Electrical Specifications: Resistance value (768 Ohms), tolerance (±1%), power rating (1W), and temperature coefficient (±100ppm/°C) must be identical.

Mechanical Compatibility: Package type (2512/6432 metric), physical dimensions (0.248" L x 0.126" W), and termination count (2) must match to ensure PCB footprint compatibility.

Environmental & Compliance Requirements: Operating temperature range (-55°C ~ 155°C), RoHS3 compliance, and MSL rating (1 - Unlimited) must be maintained.

Composition: Thick film construction is required for thermal and frequency response characteristics.

The RMCF2512FT768R from Stackpole Electronics Inc meets all substitution criteria with identical electrical and mechanical parameters. The primary distinction is the addition of AEC-Q200 automotive qualification in the substitute part, which represents an enhanced reliability standard and does not restrict its use in non-automotive applications.

Parameter Comparison

Engineering Selection Recommendations

Primary Component (RC6432F7680CS): Samsung Electro-Mechanics RC6432F7680CS is suitable for general industrial and commercial applications requiring moisture-resistant thick film resistors with ROHS3 compliance. Active product status ensures continued availability and supply chain stability.

Substitute Component (RMCF2512FT768R): Stackpole Electronics Inc RMCF2512FT768R provides identical electrical and mechanical performance with the addition of AEC-Q200 automotive qualification. This enhanced reliability standard is applicable across all application domains and does not impose restrictions on non-automotive use. The marginal height difference (0.028" vs 0.026") remains within standard PCB assembly tolerances for 2512 package components.

Both components satisfy ROHS3 compliance, MSL 1 rating, and REACH unaffected status, ensuring regulatory alignment for global markets. Selection between these parts should be based on supply availability, lead time requirements, and cost considerations, as electrical and mechanical performance are equivalent.

Frequently Asked Questions (FAQ)

Q: Can RMCF2512FT768R directly replace RC6432F7680CS on existing PCBs?

A: Yes. Both components share identical package dimensions (2512/6432 metric), footprint requirements, and electrical specifications (768 Ohms ±1%, 1W, ±100ppm/°C). The maximum seated height difference (0.028" vs 0.026") is within standard PCB assembly clearance tolerances and does not affect placement or soldering.

Q: What is the significance of AEC-Q200 qualification on the RMCF2512FT768R?

A: AEC-Q200 is an automotive industry reliability standard that specifies enhanced testing and qualification requirements. Components meeting this standard are suitable for automotive applications and also for general industrial, commercial, and consumer applications. The qualification does not restrict use outside automotive contexts.

Q: Are there any compliance or regulatory differences between these parts?

A: No. Both RC6432F7680CS and RMCF2512FT768R are ROHS3 compliant, REACH unaffected, and classified under identical ECCN (EAR99) and HTSUS codes. Regulatory requirements are equivalent for both components.

Q: What is the moisture sensitivity level (MSL) rating, and why is it important?

A: Both components carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions. These parts do not require special moisture control during storage, handling, or assembly, simplifying supply chain management and reducing production constraints.

Q: How do the temperature coefficients compare?

A: Both components specify ±100ppm/°C temperature coefficient with identical operating range (-55°C ~ 155°C). Thermal performance and frequency stability characteristics are equivalent.

Q: What packaging formats are available for these parts?

A: RC6432F7680CS is supplied in standard packaging format. RMCF2512FT768R is available in Tape & Reel (TR) format, which is standard for automated assembly processes. Packaging format selection depends on production volume and assembly equipment compatibility.
