Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC6432F300CS is determined by strict alignment of the following parameters:

Critical Matching Parameters:

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

Substitution Categories:

Direct Equivalent: RC2512FK-0730RL (YAGEO) matches all critical parameters with identical electrical and thermal specifications. Dimensions vary minimally (0.250" L x 0.122" W vs. 0.248" L x 0.126" W), remaining within 2512 package tolerance.

Upgrade Equivalent: AC2512FK-0730RL (YAGEO) maintains all critical parameters while adding AEC-Q200 automotive qualification. Identical power rating (1W), resistance, tolerance, and temperature range enable direct substitution with enhanced reliability certification.

Similar Substitutes: CRCW251230R0FKEGHP (Vishay Dale) and ERJ-1TNF30R0U (Panasonic) share all critical electrical parameters but differ in power rating (1.5W vs. 1W) and automotive qualification levels. These parts are compatible for applications where higher power dissipation capability or automotive-grade reliability is acceptable.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Equivalent Status): RC2512FK-0730RL (YAGEO) provides full electrical and mechanical equivalence to RC6432F300CS. Both parts maintain identical specifications across all critical parameters with active product status. Selection between these parts depends on supply chain availability and procurement preferences.

For Enhanced Reliability (Upgrade Status): AC2512FK-0730RL (YAGEO) is recommended when automotive-grade reliability is required. This part maintains all electrical specifications of the original while adding AEC-Q200 qualification. Active product status ensures long-term availability.

For Higher Power Dissipation Applications: CRCW251230R0FKEGHP (Vishay Dale) offers 1.5W power rating within the same 2512 package footprint. This part is suitable for applications requiring additional thermal margin while maintaining all other critical specifications. AEC-Q200 qualification provides automotive-grade reliability.

For Legacy System Maintenance: ERJ-1TNF30R0U (Panasonic) is listed as "Not For New Designs" and should be used only for repair and maintenance of existing systems. This part maintains full electrical compatibility but is not recommended for new product development.

Frequently Asked Questions (FAQ)

Q: Can RC2512FK-0730RL directly replace RC6432F300CS without circuit modification?

A: Yes. RC2512FK-0730RL matches all critical electrical parameters (30 Ohms ±1%, 1W, ±100ppm/°C, -55°C to 155°C) and package specifications (2512 / 6432 Metric). Dimensional variations (0.250" L x 0.122" W vs. 0.248" L x 0.126" W) remain within 2512 package tolerance and do not require PCB layout changes.

Q: What is the difference between RC2512FK-0730RL and AC2512FK-0730RL?

A: Both parts are manufactured by YAGEO with identical electrical specifications. AC2512FK-0730RL includes AEC-Q200 automotive qualification, making it suitable for automotive applications requiring enhanced reliability standards. RC2512FK-0730RL is the standard industrial-grade equivalent.

Q: Why is CRCW251230R0FKEGHP rated at 1.5W instead of 1W?

A: CRCW251230R0FKEGHP is a higher power variant within the same 2512 package. The 1.5W rating provides additional thermal dissipation capability. This part is compatible with RC6432F300CS in applications where higher power margin is beneficial, though the 1W specification of the original is maintained.

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

A: No. ERJ-1TNF30R0U is marked "Not For New Designs" by Panasonic. This part should be used only for repair and maintenance of existing systems. For new designs, select RC2512FK-0730RL, AC2512FK-0730RL, or CRCW251230R0FKEGHP.

Q: Do all substitute parts have the same moisture sensitivity rating?

A: Yes. All listed substitute parts maintain MSL 1 (Unlimited) rating, identical to RC6432F300CS. This ensures equivalent moisture handling and storage requirements across all alternatives.

Q: Are there dimensional differences that affect PCB assembly?

A: Dimensional variations exist within acceptable 2512 package tolerances. RC6432F300CS measures 0.248" L x 0.126" W; RC2512FK-0730RL measures 0.250" L x 0.122" W; CRCW251230R0FKEGHP measures 0.248" L x 0.124" W. All variations remain within standard 2512 specifications and do not require PCB redesign.
