Key Parameters

Substitute Part Grouping Explanation

Substitution logic is based on the following criteria:

Direct Equivalents match all critical electrical parameters: 30 Ohm resistance, ±5% tolerance, 1W power rating, 2512 package, thick film composition, and identical temperature coefficient and operating range.

Upgrade Substitutes maintain the 30 Ohm resistance, 1W power rating, and 2512 package but feature improved tolerance (±1% instead of ±5%), providing enhanced precision while remaining mechanically and thermally compatible.

Similar Substitutes maintain the 30 Ohm resistance and 2512 package but vary in power rating (1.5W instead of 1W) or include additional automotive certifications (AEC-Q200). These parts are mechanically compatible and electrically superior in power handling capacity.

All substitute parts maintain the following parameters:

• Resistance value: 30 Ohms
• Package: 2512 (6432 Metric)
• Composition: Thick Film
• Temperature Coefficient: ±100ppm/°C
• Operating Temperature: -55°C ~ 155°C
• Moisture Sensitivity Level: 1 (Unlimited)
• RoHS Status: ROHS3 Compliant
• REACH Status: REACH Unaffected

Engineering Selection Recommendations

RC2512JK-0730RL (YAGEO) serves as the direct equivalent substitute. This part maintains identical electrical specifications (30 Ω, ±5%, 1W) and mechanical compatibility with the original RC6432J300CS. Both parts are in active production status and ROHS3 compliant. This substitute is suitable for direct replacement in existing designs.

AC2512FK-0730RL (YAGEO) and RC2512FK-0730RL (YAGEO) are upgrade substitutes offering improved tolerance (±1% versus ±5%) while maintaining 1W power rating and 2512 package compatibility. Both are in active production status. AC2512FK-0730RL includes automotive AEC-Q200 certification, providing additional qualification for automotive applications. These upgrades are suitable for applications requiring tighter tolerance specifications.

CRCW251230R0FKEGHP (Vishay Dale) is a similar substitute with increased power rating (1.5W versus 1W) and automotive AEC-Q200 certification. The enhanced power rating provides additional thermal margin in applications with higher power dissipation requirements. This part is in active production status and maintains 2512 package compatibility.

ERJ-1TNF30R0U (Panasonic Electronic Components) is a similar substitute with ±1% tolerance and automotive AEC-Q200 certification. However, this part carries a "Not For New Designs" product status designation. Use of this part is restricted to legacy design support and existing inventory management only.

Frequently Asked Questions (FAQ)

Q: Can RC2512JK-0730RL replace RC6432J300CS in all applications?

A: Yes. RC2512JK-0730RL is a direct equivalent with matching electrical specifications (30 Ω, ±5%, 1W) and identical package (2512). Both parts share the same temperature coefficient, operating temperature range, and moisture sensitivity level. Mechanical dimensions are within acceptable tolerance for PCB footprint compatibility.

Q: What is the advantage of using AC2512FK-0730RL or RC2512FK-0730RL over the original part?

A: Both upgrade substitutes provide ±1% tolerance compared to the original ±5% tolerance, enabling tighter resistance value control. This improved precision is beneficial in applications requiring accurate impedance matching or precise current limiting. Both maintain the 1W power rating and 2512 package compatibility.

Q: When should CRCW251230R0FKEGHP be selected instead of the original part?

A: CRCW251230R0FKEGHP is selected when applications require higher power dissipation capability. The 1.5W rating provides 50% additional power handling compared to the 1W original specification. This part also includes automotive AEC-Q200 certification and pulse withstanding capability for demanding automotive environments.

Q: Is ERJ-1TNF30R0U suitable for new product designs?

A: No. ERJ-1TNF30R0U carries a "Not For New Designs" product status. This part is restricted to legacy design support and existing inventory management. New designs should utilize AC2512FK-0730RL, RC2512FK-0730RL, or CRCW251230R0FKEGHP as alternatives.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity level, matching the environmental and regulatory status of the original RC6432J300CS.

Q: Do substitute parts require PCB layout modifications?

A: No. All substitute parts use the 2512 (6432 Metric) package with identical footprint specifications. Mechanical dimensions are within acceptable tolerance for direct PCB footprint compatibility without layout changes.

Q: What is the difference between automotive-rated and non-automotive-rated substitutes?

A: AC2512FK-0730RL, CRCW251230R0FKEGHP, and ERJ-1TNF30R0U include automotive AEC-Q200 certification, indicating qualification for automotive temperature cycling, vibration, and reliability requirements. RC2512JK-0730RL and RC2512FK-0730RL do not carry automotive certification but remain suitable for general industrial and consumer applications.
