Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RC6432F180CS are qualified based on the following critical parameters that determine functional interchangeability:

Electrical Parameters (Must Match):

• Resistance value: 18 Ohms
• Tolerance: ±1%
• Power rating: 1W
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C

Mechanical Parameters (Must Match):

• Package type: 2512 (6432 Metric)
• Number of terminations: 2
• Physical dimensions within tolerance band (length, width, height)

Environmental & Compliance Parameters (Must Match):

• Composition: Thick Film
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)
• REACH Status: REACH Unaffected

All identified substitute parts meet these criteria. Additional features such as Automotive AEC-Q200 certification present in some substitutes represent enhanced qualification levels and do not prevent substitution in non-automotive applications.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts are functionally equivalent to the RC6432F180CS based on matching electrical and mechanical specifications. Selection among these alternatives should be based on the following factors:

Direct Equivalence (No Additional Certifications): RC2512FK-0718RL from YAGEO provides direct substitution with identical electrical and thermal characteristics. This part is suitable for general industrial and commercial applications where moisture-resistant thick film construction is the primary requirement.

Enhanced Automotive Qualification: CRCW251218R0FKEG (Vishay Dale) and RMCF2512FT18R0 (Stackpole Electronics Inc) both carry Automotive AEC-Q200 certification. These parts meet additional automotive industry qualification standards and are suitable for both automotive and non-automotive applications. The AEC-Q200 rating does not restrict use in non-automotive circuits and represents an enhanced qualification level.

Availability and Packaging: All substitute parts are supplied in Tape & Reel (TR) packaging format. Inventory levels vary: RC2512FK-0718RL (3306 pcs), CRCW251218R0FKEG (79234 pcs), and RMCF2512FT18R0 (8360 pcs). Selection may be influenced by supply chain requirements and lead time considerations.

Dimensional Tolerance: Physical dimensions across all parts fall within acceptable tolerance bands for 2512 package specifications. Height variations (0.026" to 0.028") remain within standard PCB assembly clearance requirements.

Frequently Asked Questions (FAQ)

Q: Can RC2512FK-0718RL be used as a direct replacement for RC6432F180CS?

A: Yes. RC2512FK-0718RL matches all critical electrical parameters (18 Ohms, ±1%, 1W), thermal characteristics (±100ppm/°C, -55°C to 155°C), mechanical specifications (2512 package), and environmental compliance (ROHS3, MSL 1). Direct substitution is supported.

Q: What is the difference between the Samsung part and the Vishay Dale CRCW251218R0FKEG?

A: Both parts are electrically and mechanically equivalent. The primary difference is that CRCW251218R0FKEG carries Automotive AEC-Q200 certification, indicating qualification for automotive applications. This certification does not restrict use in non-automotive circuits. Physical dimensions are within tolerance band specifications for the 2512 package.

Q: Are the Stackpole RMCF2512FT18R0 and Vishay Dale CRCW251218R0FKEG interchangeable?

A: Yes. Both parts share identical electrical specifications, thermal performance, and package type. Both carry AEC-Q200 automotive certification. Minor dimensional variations (height 0.028" for both) fall within standard PCB assembly tolerances. Interchangeability is supported.

Q: Does the YAGEO RC2512FK-0718RL lack automotive qualification?

A: The RC2512FK-0718RL does not carry AEC-Q200 certification. However, it meets all electrical, thermal, and environmental specifications required for the 2512 package 18 Ohm 1W resistor. Selection should be based on application requirements. For non-automotive applications, this part is fully qualified.

Q: What is the significance of MSL 1 (Unlimited) rating?

A: MSL 1 indicates unlimited shelf life without moisture bake-out requirements. All substitute parts carry this rating, meaning they can be stored and handled without special moisture control procedures prior to assembly.

Q: Can these parts be used interchangeably in high-temperature applications?

A: Yes. All parts operate across the identical temperature range of -55°C to 155°C with matching temperature coefficient of ±100ppm/°C. Thermal performance is equivalent across all substitutes.

Q: Are there packaging format differences among the substitutes?

A: All substitute parts are supplied in Tape & Reel (TR) format. The main part (RC6432F180CS) is listed with "-" packaging designation. For production assembly requiring tape and reel format, all three substitutes are compatible.
