Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC6432F1020CS is determined by the following critical parameters:

Electrical Equivalence Requirements:

• Resistance value: 102 Ohms (exact match required)
• Tolerance: ±1% (exact match required)
• Temperature Coefficient: ±100ppm/°C (exact match required)
• Operating Temperature Range: -55°C ~ 155°C (minimum requirement)

Mechanical Compatibility Requirements:

• Package / Case: 2512 (6432 Metric) (exact match required)
• Composition: Thick Film (exact match required)
• Number of Terminations: 2 (exact match required)

Compliance Requirements:

• RoHS Status: ROHS3 Compliant (minimum requirement)
• Moisture Sensitivity Level: 1 (Unlimited) (minimum requirement)

The CRCW2512102RFKEGHP by Vishay Dale qualifies as a substitute part because it maintains all critical electrical parameters, identical package specifications, and equivalent environmental ratings. The higher power rating (1.5W versus 1W) represents an uprated capability that does not compromise the original design requirements.

Parameter Comparison

Engineering Selection Recommendations

Primary Part Selection (RC6432F1020CS): The Samsung Electro-Mechanics RC6432F1020CS is suitable for applications requiring a 102 Ohm 1W thick film resistor in 2512 package format. This part maintains active production status and carries ROHS3 compliance with unlimited moisture sensitivity rating. Selection is appropriate for standard industrial and consumer applications within the specified temperature range.

Substitute Part Selection (CRCW2512102RFKEGHP): The Vishay Dale CRCW2512102RFKEGHP provides functional equivalence with identical electrical specifications and package compatibility. The uprated 1.5W power capability offers additional thermal margin without altering circuit behavior. This part includes AEC-Q200 automotive qualification and pulse withstanding capability, making it suitable for applications requiring enhanced reliability. Both parts maintain equivalent compliance certifications and environmental ratings.

Selection Criteria:

• Choose the primary part when Samsung Electro-Mechanics supply chain preference or existing qualification documentation exists
• Choose the substitute part when Vishay Dale supply availability is superior or when automotive-grade reliability is required
• Both parts are interchangeable from electrical and mechanical perspectives within the specified operating parameters

Frequently Asked Questions (FAQ)

Q: Can the CRCW2512102RFKEGHP directly replace the RC6432F1020CS in existing designs?

A: Yes. Both parts share identical resistance (102 Ohms), tolerance (±1%), temperature coefficient (±100ppm/°C), operating temperature range (-55°C ~ 155°C), and 2512 package dimensions. The substitute part's higher power rating (1.5W) does not create compatibility issues and provides additional thermal headroom.

Q: What is the significance of the 1.5W versus 1W power rating difference?

A: The CRCW2512102RFKEGHP is rated for 1.5W continuous power dissipation compared to the RC6432F1020CS at 1W. In applications where the original design dissipates less than 1W, the substitute part operates with additional thermal margin. No circuit redesign is required.

Q: Are the physical dimensions identical between these two parts?

A: Both parts use the 2512 (6432 Metric) package. The RC6432F1020CS measures 0.248" L x 0.126" W (6.30mm x 3.20mm) with 0.026" maximum seated height. The CRCW2512102RFKEGHP measures 0.248" L x 0.124" W (6.30mm x 3.15mm) with 0.028" maximum seated height. These dimensional variations are within standard PCB footprint tolerances and do not affect placement or soldering.

Q: Do both parts meet the same compliance requirements?

A: Yes. Both the RC6432F1020CS and CRCW2512102RFKEGHP are ROHS3 compliant, REACH unaffected, and carry MSL 1 (Unlimited) moisture sensitivity rating. Both are classified under ECCN EAR99 and HTSUS 8533.21.0030.

Q: What distinguishes the CRCW2512102RFKEGHP as an automotive-grade component?

A: The Vishay Dale part carries AEC-Q200 automotive qualification and pulse withstanding capability. These certifications indicate enhanced reliability testing and performance validation for automotive applications. The RC6432F1020CS does not carry these specific automotive certifications.

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

A: Both parts are suitable for high-reliability applications. The RC6432F1020CS provides standard industrial-grade performance. The CRCW2512102RFKEGHP offers automotive-grade qualification with pulse withstanding capability, making it the preferred choice when automotive or enhanced reliability standards are specified.
