• Composition: Thick Film
• Temperature Coefficient: ±100ppm/°C
• Operating Temperature Range: -55°C ~ 155°C
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Allowable Variation Parameters:

• Tolerance: ±5% (main part) to ±1% (upgrade substitutes)
• Power Rating: 1W (main part) to 2W (higher capacity substitutes)
• Packaging format: Bulk or Tape & Reel (TR)
• Manufacturer: Samsung Electro-Mechanics, YAGEO, Bourns Inc.

Substitution Categories:

Direct Equivalent: RC2512JK-076K8L (YAGEO) maintains identical electrical specifications (6.8 kOhms ±5% 1W) with compatible mechanical dimensions and packaging in Tape & Reel format.

Upgrade Substitute: RC2512FK-076K8L (YAGEO) provides improved tolerance (±1% vs ±5%) while maintaining 1W power rating and all other critical parameters.

Higher Capacity Substitute: CRM2512-FX-6801ELF (Bourns Inc.) increases power rating to 2W with improved tolerance (±1%) for applications requiring additional thermal margin, while maintaining 6.8 kOhms resistance and 2512 package compatibility.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Pin-Compatible, Specification-Matched): RC2512JK-076K8L (YAGEO) is the direct equivalent substitute. This part maintains identical electrical specifications (6.8 kOhms ±5% 1W), matching temperature coefficient, operating range, and compliance certifications. Mechanical dimensions are within acceptable tolerance for 2512 package footprints. All parts carry ROHS3 compliance and MSL 1 rating. Selection of this substitute is appropriate when Samsung Electro-Mechanics RC6432J682CS availability is constrained and YAGEO supply is confirmed.

For Improved Tolerance Applications: RC2512FK-076K8L (YAGEO) upgrades tolerance from ±5% to ±1% while maintaining 1W power rating and all other critical parameters. This substitute is suitable for circuits requiring tighter resistance accuracy without increasing thermal dissipation requirements. Active product status and ROHS3 compliance are maintained.

For Higher Power Margin Applications: CRM2512-FX-6801ELF (Bourns Inc.) increases power rating to 2W with ±1% tolerance. This substitute accommodates applications with higher current density or thermal stress while maintaining 6.8 kOhms resistance and 2512 package compatibility. Maximum seated height increases to 0.031" (0.80mm); PCB layout clearance verification is required. All regulatory certifications remain compliant.

All substitute parts are active production items with confirmed inventory availability and maintain ROHS3 compliance and MSL 1 moisture sensitivity rating.

Frequently Asked Questions (FAQ)

Q: Can RC2512JK-076K8L replace RC6432J682CS in existing designs without PCB modification?

A: Yes. Both parts use the 2512 (6432 Metric) package with compatible footprints. Dimensional variations (length 0.248" vs 0.250", width 0.126" vs 0.122", height 0.026" vs 0.026") are within standard PCB pad tolerance for this package class. No PCB redesign is required.

Q: What is the difference between the ±5% tolerance main part and the ±1% tolerance upgrade?

A: RC6432J682CS specifies ±5% tolerance, meaning the actual resistance can vary between 6.46 kOhms and 7.14 kOhms. RC2512FK-076K8L specifies ±1% tolerance, constraining actual resistance between 6.73 kOhms and 6.87 kOhms. The upgrade provides tighter resistance accuracy for precision circuits. Both maintain identical power rating, temperature coefficient, and operating range.

Q: Why does CRM2512-FX-6801ELF have a higher maximum seated height (0.031" vs 0.026")?

A: The CRM2512-FX-6801ELF is rated for 2W power dissipation compared to 1W for the main part. The increased height accommodates thicker internal resistive film required for higher power handling. PCB layout must verify clearance in the vertical dimension; this part is not suitable for space-constrained applications with height restrictions below 0.031".

Q: Are all substitute parts ROHS3 compliant?

A: Yes. RC2512JK-076K8L, RC2512FK-076K8L, and CRM2512-FX-6801ELF all carry ROHS3 Compliant certification. All parts maintain MSL 1 (Unlimited) moisture sensitivity rating, requiring no special handling or storage conditions.

Q: What packaging formats are available for these substitutes?

A: RC2512JK-076K8L and RC2512FK-076K8L are supplied in Tape & Reel (TR) format. CRM2512-FX-6801ELF is also supplied in Tape & Reel (TR) format. Bulk packaging availability should be confirmed with the respective manufacturer or authorized distributor for specific procurement requirements.

Q: Can CRM2512-FX-6801ELF be used in applications designed for 1W resistors?

A: Yes. CRM2512-FX-6801ELF is rated for 2W, which exceeds the 1W requirement of the original design. The part will operate safely at or below 1W dissipation. The higher power rating provides thermal margin and extended component life in the application. Verify PCB layout accommodates the 0.031" maximum seated height.

Q: What is the temperature coefficient specification and does it vary across substitutes?

A: All parts, including the main RC6432J682CS and all substitutes, specify ±100ppm/°C temperature coefficient. This parameter is identical across all options and does not vary based on tolerance grade or power rating.
