Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC6432F5900CS is determined by strict equivalence across the following critical parameters:

Primary Substitution Criteria:

• Resistance value: 590 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

Secondary Consideration:

• Power Rating: 1W minimum (higher ratings acceptable for direct substitution)

All identified substitute parts meet or exceed these parameters. Parts are grouped by manufacturer and product status to facilitate selection based on availability and certification requirements.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Active Status):

AC2512FK-07590RL (YAGEO) and RMCF2512FT590R (Stackpole Electronics Inc) are direct functional equivalents with active product status. Both parts maintain identical electrical specifications and thermal characteristics. AC2512FK-07590RL includes automotive AEC-Q200 certification. RMCF2512FT590R also carries AEC-Q200 qualification. Selection between these options depends on supply chain preference and packaging format requirements (Tape & Reel).

Enhanced Performance Option:

CRCW2512590RFKEGHP (Vishay Dale) provides 1.5W power rating while maintaining all other electrical parameters. This part is suitable for applications requiring additional thermal margin or pulse withstanding capability. AEC-Q200 certification is included.

Legacy Consideration:

ERJ-1TNF5900U (Panasonic Electronic Components) meets all electrical and thermal specifications but carries "Not For New Designs" status. This part remains available with substantial inventory (18,197 pieces) and is suitable only for legacy system maintenance or existing design continuity where new qualification is not required.

Frequently Asked Questions (FAQ)

Q: Can AC2512FK-07590RL replace RC6432F5900CS in all applications?

A: Yes. AC2512FK-07590RL meets all electrical, thermal, and compliance parameters of the RC6432F5900CS. The primary difference is packaging format (Tape & Reel versus Bulk) and the addition of automotive AEC-Q200 certification, which does not restrict use in non-automotive applications.

Q: What is the significance of the 1.5W rating on CRCW2512590RFKEGHP?

A: The 1.5W rating on CRCW2512590RFKEGHP exceeds the 1W requirement of RC6432F5900CS. This part can be substituted directly; the higher power rating provides additional thermal headroom and pulse withstanding capability without affecting electrical performance at 1W operation.

Q: Why is ERJ-1TNF5900U marked "Not For New Designs"?

A: "Not For New Designs" indicates the manufacturer has discontinued active development of this product line. While the part remains functionally equivalent and available in inventory, it is not recommended for new product development. Use this part only for legacy system support or existing design continuity.

Q: Are all substitute parts automotive-qualified?

A: AC2512FK-07590RL, CRCW2512590RFKEGHP, ERJ-1TNF5900U, and RMCF2512FT590R all carry AEC-Q200 automotive qualification. RC6432F5900CS does not list AEC-Q200 certification. For automotive applications, substitute parts provide additional qualification assurance.

Q: Does packaging format affect electrical performance?

A: No. Packaging format (Bulk versus Tape & Reel) affects handling, storage, and assembly processes but does not alter electrical characteristics, thermal performance, or reliability of the resistor element itself.

Q: Can these parts be used interchangeably in PCB assembly?

A: Yes, provided the PCB footprint accommodates the 2512 (6432 Metric) package. Dimensional variations between manufacturers are within tolerance for standard PCB design. Verify maximum height specifications if space constraints exist: RC6432F5900CS (0.66mm), AC2512FK-07590RL (0.65mm), CRCW2512590RFKEGHP (0.70mm), ERJ-1TNF5900U (0.70mm), RMCF2512FT590R (0.70mm).
