RC1005F9312CS Equivalent & Substitute Parts Reference

Part Overview

The RC1005F9312CS is a 93.1 kOhms ±1% thick film chip resistor manufactured by Samsung Electro-Mechanics in 0402 (1005 Metric) package format. This surface mount device is rated for 0.063W (1/16W) power dissipation and operates across the temperature range of -55°C to 155°C. The component features moisture resistance and is ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating. The part is currently in active production status with 923 pieces available in inventory.

Equivalent and substitute parts are necessary when the primary manufacturer part becomes unavailable, when supply chain optimization is required, or when design specifications allow for alternative qualified sources meeting identical or enhanced electrical and mechanical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC1005F9312CS is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 93.1 kOhms
• Tolerance: ±1%
• Package / Case: 0402 (1005 Metric)
• Composition: Thick Film
• Temperature Coefficient: ±100ppm/°C
• Operating Temperature Range: -55°C ~ 155°C
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Allowable Variation:

• Power Rating: Substitute parts may equal or exceed the 0.063W (1/16W) specification
• Packaging Format: Both Tape & Reel (TR) and Cut Tape (CT) formats are acceptable for equivalent substitution
• Features: Additional features such as Automotive AEC-Q200 qualification or enhanced moisture resistance do not disqualify a part from substitution

All identified substitute parts meet or exceed the mandatory parameters of the RC1005F9312CS.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed are in active production status and maintain ROHS3 compliance with MSL 1 rating, ensuring compatibility with standard PCB assembly processes and environmental requirements.

Direct Equivalents (Identical Electrical and Mechanical Specifications):

• CR0402-FX-9312GLF (Bourns Inc.)
• RC0402FR-0793K1L (YAGEO)
• AC0402FR-0793K1L (YAGEO)
• CRCW040293K1FKED (Vishay Dale)
• RMCF0402FT93K1 (Stackpole Electronics Inc)

These parts match all critical parameters of the RC1005F9312CS and are suitable for direct substitution in applications where the original specification is maintained.

Upgraded Alternative (Enhanced Power Rating):

• ERJ-2RKF9312X (Panasonic Electronic Components)

This part exceeds the power rating specification at 0.1W (1/10W) versus the 0.063W (1/16W) of the primary part. The higher power rating provides additional thermal margin and is compatible with designs requiring the RC1005F9312CS specification. This part is available in Cut Tape (CT) & Digi-Reel® packaging format.

Frequently Asked Questions (FAQ)

Q: Can ERJ-2RKF9312X be used as a direct replacement for RC1005F9312CS?

A: Yes. The ERJ-2RKF9312X meets all mandatory electrical parameters (93.1 kOhms, ±1% tolerance, ±100ppm/°C temperature coefficient, -55°C to 155°C operating range) and mechanical specifications (0402 package). The higher power rating of 0.1W exceeds the 0.063W requirement and does not create compatibility issues. The primary difference is packaging format (Cut Tape vs. Tape & Reel), which affects handling and assembly processes but not electrical performance.

Q: What is the significance of the 0402 (1005 Metric) package designation?

A: The 0402 package designation refers to the physical dimensions of the chip resistor: 0.039" length × 0.020" width (1.00mm × 0.50mm). All listed substitute parts share this identical package footprint, ensuring mechanical compatibility with PCB layouts designed for the RC1005F9312CS. The metric designation (1005) is equivalent to the imperial designation (0402).

Q: Are there differences in moisture resistance between substitute parts?

A: The RC1005F9312CS and RC0402FR-0793K1L are explicitly specified as moisture resistant. Other substitute parts do not list moisture resistance as a feature specification. However, all parts maintain MSL 1 (Unlimited) moisture sensitivity rating, indicating they do not require special moisture control during storage or assembly. The absence of a moisture resistance feature designation does not indicate inferior performance in standard manufacturing environments.

Q: What is the difference between Tape & Reel (TR) and Cut Tape (CT) packaging?

A: Tape & Reel (TR) packaging supplies components on continuous carrier tape wound on reels, suitable for automated pick-and-place assembly equipment. Cut Tape (CT) packaging supplies components on cut segments of carrier tape, typically used for manual assembly or lower-volume production. Both formats contain identical components; the difference is in supply format and handling. The ERJ-2RKF9312X is available in Cut Tape (CT) & Digi-Reel® format, which may require different feeder compatibility on assembly equipment.

Q: Do all substitute parts have the same temperature coefficient?

A: Yes. All substitute parts, including the primary RC1005F9312CS, specify a temperature coefficient of ±100ppm/°C. This parameter is identical across all listed alternatives and is a mandatory matching criterion for substitution eligibility.

Q: What does ROHS3 compliance indicate?

A: ROHS3 compliance indicates conformance to the Restriction of Hazardous Substances Directive 3, which restricts the use of specific hazardous materials in electrical and electronic equipment. All listed parts are ROHS3 compliant, confirming they meet environmental and regulatory requirements for use in consumer and industrial applications.

Q: Can substitute parts be mixed within a single production run?

A: Yes. All substitute parts meet identical electrical specifications and mechanical package requirements. Mixing substitute parts from different manufacturers within a single PCB assembly is permissible from an engineering standpoint, provided assembly equipment is compatible with the packaging formats used (Tape & Reel vs. Cut Tape).
