Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RC6432F64R9CS are qualified based on the following electrical and mechanical parameters:

Electrical Equivalence Criteria:

• Resistance value: 64.9 Ohms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 1W (exact match required)
• Temperature coefficient: ±100ppm/°C (exact match required)
• Operating temperature range: -55°C ~ 155°C (exact match required)

Mechanical Equivalence Criteria:

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

Compliance Criteria:

• RoHS Status: ROHS3 Compliant (minimum requirement)
• MSL Rating: 1 (Unlimited) (minimum requirement)
• REACH Status: REACH Unaffected (minimum requirement)

All identified substitute parts meet these criteria. The AC2512FK-0764R9L and CRCW251264R9FKEG additionally carry AEC-Q200 automotive qualification, which represents an enhancement to the base specification rather than a deviation.

Parameter Comparison

Engineering Selection Recommendations

Primary Part: RC6432F64R9CS Select this Samsung Electro-Mechanics component when the original specification is required and inventory availability is sufficient. The part maintains active production status with ROHS3 compliance and MSL 1 rating.

Upgrade Option: AC2512FK-0764R9L This YAGEO substitute provides identical electrical and mechanical specifications with the addition of AEC-Q200 automotive qualification. Select this part when automotive-grade reliability is required or when higher inventory levels are needed. Packaging is supplied as Tape & Reel (TR).

Alternative Option: CRCW251264R9FKEG This Vishay Dale substitute meets all electrical and mechanical requirements with AEC-Q200 automotive qualification. This part offers the highest inventory availability (20942 pieces) and is suitable for applications requiring automotive-grade components. Packaging is supplied as Tape & Reel (TR).

All three parts are ROHS3 compliant, REACH unaffected, and carry MSL 1 (Unlimited) ratings, ensuring compatibility across standard industrial and automotive applications.

Frequently Asked Questions (FAQ)

Q: Can AC2512FK-0764R9L be used as a direct replacement for RC6432F64R9CS? A: Yes. Both parts share identical electrical specifications (64.9 Ohms ±1%, 1W, ±100ppm/°C, -55°C to 155°C) and mechanical package (2512/6432 Metric). The YAGEO part includes AEC-Q200 automotive qualification as an enhancement. Tape & Reel packaging differs from the original specification but does not affect functional compatibility.

Q: What is the difference between the three substitute options? A: All three parts meet the core electrical and mechanical requirements. RC6432F64R9CS (Samsung) is the original specification. AC2512FK-0764R9L (YAGEO) and CRCW251264R9FKEG (Vishay Dale) both add AEC-Q200 automotive qualification. The primary differences are manufacturer, packaging format (Tape & Reel for substitutes), and inventory availability.

Q: Is moisture resistance a critical factor in selecting a substitute? A: The RC6432F64R9CS and AC2512FK-0764R9L both specify moisture resistance. The CRCW251264R9FKEG does not list this feature in the provided specifications. If moisture resistance is a design requirement, AC2512FK-0764R9L is the preferred substitute.

Q: Can I use CRCW251264R9FKEG in place of RC6432F64R9CS? A: Yes, from an electrical and mechanical standpoint. Both parts are 64.9 Ohms ±1%, 1W, 2512 package, with identical temperature coefficients and operating ranges. However, moisture resistance is not specified for the Vishay Dale part. Verify moisture resistance requirements before selection.

Q: What does AEC-Q200 qualification mean? A: AEC-Q200 is an automotive industry standard for passive components. Parts carrying this qualification have undergone additional reliability testing and are suitable for automotive applications. This is an enhancement to the base specification and does not restrict use in non-automotive applications.

Q: Are there packaging differences between these parts? A: Yes. The original RC6432F64R9CS packaging format is not specified in the provided data. Both substitute parts (AC2512FK-0764R9L and CRCW251264R9FKEG) are supplied in Tape & Reel (TR) format. Verify that your assembly process accommodates Tape & Reel packaging if switching from the original part.

Q: Which substitute has the best inventory availability? A: CRCW251264R9FKEG (Vishay Dale) has the highest inventory with 20942 pieces available, followed by AC2512FK-0764R9L (YAGEO) with 12688 pieces. The original RC6432F64R9CS has 713 pieces in stock.
