Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RC6432F682CS are classified based on strict electrical and mechanical parameter alignment:

Direct Substitutes maintain identical electrical specifications (6.8 kOhms, ±1% tolerance, 1W power rating) and mechanical compatibility (2512 package, thick film composition, ±100ppm/°C temperature coefficient, -55°C to 155°C operating range, ROHS3 compliance, MSL 1 rating).

Similar Substitutes share the same resistance value, tolerance, package, composition, temperature coefficient, and operating range but differ in power rating or application-specific features. These parts are compatible in circuits where the higher power rating does not create thermal or space constraints.

The 2512 package footprint and dimensional specifications are the primary mechanical constraints. All substitute candidates maintain the same number of terminations (2) and RoHS/REACH compliance status.

Parameter Comparison

Engineering Selection Recommendations

RC2512FK-076K8L (YAGEO) is a direct substitute for RC6432F682CS. Both parts share identical electrical specifications (6.8 kOhms, ±1%, 1W), matching composition, temperature characteristics, and compliance certifications. Dimensional variations are within typical PCB layout tolerances. This part is suitable for direct replacement in existing designs without circuit modification.

CRM2512-FX-6801ELF (Bourns) is a similar substitute with higher power rating (2W versus 1W). The increased power capability allows operation in higher dissipation environments. The maximum seated height is 0.031" (0.80mm) compared to 0.026" (0.66mm) for the primary part; verification of PCB clearance is necessary in space-constrained applications. This part maintains all electrical and compliance requirements. The current sense feature indicates application-specific design; use is appropriate where this functionality aligns with circuit requirements.

All three parts maintain ROHS3 compliance, MSL 1 rating, and active production status, ensuring long-term availability and supply chain stability.

Frequently Asked Questions (FAQ)

Q: Can RC2512FK-076K8L replace RC6432F682CS in all applications?

A: Yes. RC2512FK-076K8L is a direct substitute with identical electrical specifications, package footprint, and compliance ratings. No circuit modifications are required.

Q: What is the difference between the 1W and 2W power ratings?

A: Power rating indicates maximum continuous power dissipation. The 2W CRM2512-FX-6801ELF can dissipate twice the power of the 1W parts. Use the 2W part only if circuit design requires higher power handling; oversizing does not improve performance in lower-power applications.

Q: Are dimensional differences between parts significant?

A: Length and width variations (0.248" to 0.250" and 0.122" to 0.126") are within standard PCB design tolerances. Height differences (0.026" to 0.031") may affect clearance in space-constrained designs; verify PCB layout before substitution.

Q: Do all substitute parts meet the same environmental standards?

A: Yes. All three parts are ROHS3 compliant, REACH unaffected, and rated MSL 1 (unlimited moisture sensitivity). Operating temperature range (-55°C to 155°C) and temperature coefficient (±100ppm/°C) are identical across all parts.

Q: What does "Current Sense" feature mean on the Bourns part?

A: Current sense resistors are designed for precision current measurement applications. The CRM2512-FX-6801ELF maintains the same resistance and tolerance specifications but is optimized for this application. Use this part when circuit design specifically requires current sensing functionality.

Q: Can I use these parts interchangeably in production?

A: RC2512FK-076K8L is fully interchangeable. CRM2512-FX-6801ELF requires design verification due to higher power rating and height. Confirm PCB layout compatibility and application requirements before production implementation.
