Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC1005F9761CS is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 9.76 kOhms
• Tolerance: ±1%
• Package / Case: 0402 (1005 Metric)
• Composition: Thick Film
• Temperature Coefficient: ±100ppm/°C
• Operating Temperature Range: -55°C ~ 155°C
• Moisture Sensitivity Level: 1 (Unlimited)
• RoHS Status: ROHS3 Compliant
• Number of Terminations: 2

Allowable Variation:

• Power rating: Substitute parts may equal or exceed the 0.063W (1/16W) rating
• Physical dimensions: Minor variations within package specification tolerance
• Packaging format: Tape & Reel (TR) or Cut Tape (CT) & Digi-Reel® formats are interchangeable for component selection
• Additional certifications: Automotive AEC-Q200 qualification is an enhancement and does not preclude substitution

Substitute parts are classified as Direct, Upgrade, or Similar based on exact parameter matching and additional feature sets.

Parameter Comparison

Engineering Selection Recommendations

Direct Substitutes (Functionally Equivalent):

CR0402-FX-9761GLF (Bourns Inc.) and RC0402FR-079K76L (YAGEO) are direct functional equivalents to the RC1005F9761CS. Both parts match all mandatory electrical parameters, package specifications, and compliance requirements. RC0402FR-079K76L includes moisture-resistant construction matching the original part specification. Selection between these options is based on packaging format preference (Cut Tape & Digi-Reel® versus Tape & Reel) and inventory availability.

Upgrade Substitute (Enhanced Performance):

ERJ-2RKF9761X (Panasonic Electronic Components) provides an upgrade path with increased power rating of 0.1W (1/10W) compared to the 0.063W (1/16W) rating of the original part. This component includes Automotive AEC-Q200 qualification, suitable for applications requiring automotive-grade reliability. The upgrade maintains all other electrical and thermal specifications.

Similar Substitutes (Enhanced Features):

AC0402FR-079K76L (YAGEO), CRCW04029K76FKED (Vishay Dale), and RMCF0402FT9K76 (Stackpole Electronics Inc) are functionally equivalent with the addition of Automotive AEC-Q200 certification. These parts maintain identical electrical performance and package specifications while providing automotive-grade qualification. AC0402FR-079K76L additionally includes moisture-resistant construction. Selection is appropriate for applications requiring automotive-grade components or where enhanced reliability certification is specified.

All substitute parts maintain RoHS3 compliance, MSL 1 (Unlimited) moisture sensitivity rating, and identical operating temperature ranges. Product status is Active for all listed alternatives, ensuring continued availability and supply chain support.

Frequently Asked Questions (FAQ)

Q: Can CR0402-FX-9761GLF be used as a direct replacement for RC1005F9761CS?

A: Yes. CR0402-FX-9761GLF is a direct functional equivalent. Both parts share identical resistance (9.76 kOhms), tolerance (±1%), power rating (0.063W), package (0402), temperature coefficient (±100ppm/°C), operating temperature range (-55°C ~ 155°C), and compliance specifications (RoHS3, MSL 1). The primary difference is packaging format: CR0402-FX-9761GLF is supplied in Cut Tape & Digi-Reel® format while RC1005F9761CS is supplied in Tape & Reel format.

Q: What is the difference between the RC1005F9761CS and ERJ-2RKF9761X?

A: The primary difference is power rating. ERJ-2RKF9761X is rated for 0.1W (1/10W) compared to RC1005F9761CS at 0.063W (1/16W). All other electrical parameters are identical. ERJ-2RKF9761X includes Automotive AEC-Q200 certification, which RC1005F9761CS does not specify. ERJ-2RKF9761X is suitable for applications requiring higher power dissipation capability or automotive-grade qualification.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts are RoHS3 compliant, matching the compliance status of RC1005F9761CS. All parts also maintain MSL 1 (Unlimited) moisture sensitivity rating and REACH Unaffected status.

Q: Does moisture-resistant construction affect substitution eligibility?

A: Moisture-resistant construction is a feature enhancement and does not preclude substitution. RC0402FR-079K76L and AC0402FR-079K76L include moisture-resistant construction matching the original part. CR0402-FX-9761GLF does not specify this feature but remains functionally equivalent for applications not requiring explicit moisture resistance specification.

Q: Can I use CRCW04029K76FKED in place of RC1005F9761CS in non-automotive applications?

A: Yes. CRCW04029K76FKED is functionally equivalent to RC1005F9761CS across all electrical and thermal parameters. The Automotive AEC-Q200 certification is an additional qualification that does not restrict use in non-automotive applications. Selection is based on electrical performance requirements, not certification level.

Q: What is the significance of the 0402 package designation?

A: The 0402 package (1005 Metric) is the physical form factor specifying component dimensions of 0.039" L x 0.020" W (1.00mm x 0.50mm). All listed substitute parts use identical 0402 packaging, ensuring mechanical compatibility with printed circuit board layouts and assembly equipment. Packaging format (Tape & Reel versus Cut Tape & Digi-Reel®) refers to supply method and does not affect component performance or board-level compatibility.

Q: Are there inventory considerations when selecting substitute parts?

A: Inventory availability varies by manufacturer and supplier. RC0402FR-079K76L (YAGEO) shows the highest inventory level at 107,158 pieces. RMCF0402FT9K76 (Stackpole Electronics Inc) shows 364,265 pieces available. Inventory levels should be verified with current suppliers as availability changes over time.

Q: What temperature coefficient specification applies to all parts?

A: All listed parts, including RC1005F9761CS and all substitutes, specify a temperature coefficient of ±100ppm/°C. This parameter is identical across all alternatives and does not differentiate substitution eligibility.
