RC1005F1023CS Equivalent & Substitute Parts Reference

Part Overview

The RC1005F1023CS is a 102 kOhms ±1% thick film chip resistor manufactured by Samsung Electro-Mechanics in 0402 (1005 Metric) package format. This component is rated at 0.063W (1/16W) power dissipation with moisture-resistant construction and operates across the temperature range of -55°C to 155°C. The part maintains Active product status with ROHS3 compliance and unlimited moisture sensitivity level (MSL 1).

Equivalent and substitute parts are identified based on matching electrical specifications (resistance value, tolerance, power rating, temperature coefficient), mechanical compatibility (package size, dimensions, termination count), and environmental ratings. Alternative sources provide design flexibility, supply chain redundancy, and application-specific feature enhancements such as automotive qualification.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict alignment with the following core parameters:

Electrical Equivalence Requirements:

• Resistance value: 102 kOhms (exact match)
• Tolerance: ±1% (exact match)
• Temperature coefficient: ±100ppm/°C (exact match)
• Operating temperature range: -55°C to 155°C (exact match or wider)

Mechanical Compatibility Requirements:

• Package / Case: 0402 (1005 Metric) (exact match)
• Size / Dimension: 0.039" L x 0.020" W (1.00mm x 0.50mm) (exact match)
• Number of Terminations: 2 (exact match)

Environmental & Compliance Requirements:

• RoHS Status: ROHS3 Compliant (for primary substitutes)
• Moisture Sensitivity Level: 1 (Unlimited) (exact match)
• REACH Status: REACH Unaffected (for primary substitutes)

Power Rating Consideration:

• Direct substitutes maintain 0.063W (1/16W) rating
• Upgrade substitutes may feature higher power ratings (0.1W / 1/10W) while maintaining all other parameters

Substitute parts are categorized as Direct (identical specifications), Upgrade (enhanced power rating), or Similar (additional certifications such as AEC-Q200 automotive qualification).

Parameter Comparison

Engineering Selection Recommendations

Direct Substitutes (Identical Specifications):

CR0402-FX-1023GLF (Bourns Inc.) and RC0402FR-07102KL (YAGEO) are direct electrical and mechanical equivalents to the RC1005F1023CS. Both maintain ROHS3 compliance, identical power ratings, and matching package dimensions. RC0402FR-07102KL includes moisture-resistant construction matching the original part specification. These substitutes are suitable for applications requiring no design modification.

Upgrade Substitute (Enhanced Power Rating):

ERJ-2RKF1023X (Panasonic Electronic Components) provides a higher power rating of 0.1W (1/10W) while maintaining all other electrical and mechanical parameters. This part carries AEC-Q200 automotive qualification. The upgrade is applicable in designs where increased thermal margin is beneficial or where automotive-grade components are required.

Similar Substitutes (Automotive Qualification):

AC0402FR-07102KL (YAGEO), CRCW0402102KFKED (Vishay Dale), and RMCF0402FT102K (Stackpole Electronics Inc) are functionally equivalent with the addition of AEC-Q200 automotive qualification. All three maintain ROHS3 compliance and identical electrical specifications. AC0402FR-07102KL includes moisture-resistant features. These parts are suitable for automotive applications or designs requiring automotive-grade component reliability.

Non-Compliant Substitute (Restricted Use):

CRCW0402102KFKTD (Vishay Dale) is electrically and mechanically equivalent but carries RoHS non-compliant status and REACH Affected designation. This part is not suitable for applications subject to RoHS3 or REACH regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can CR0402-FX-1023GLF replace RC1005F1023CS in any application?

A: CR0402-FX-1023GLF is a direct electrical and mechanical equivalent. Both parts share identical resistance (102 kOhms), tolerance (±1%), power rating (0.063W), temperature coefficient (±100ppm/°C), package size (0402), and compliance status (ROHS3). Direct substitution is valid without design modification.

Q: What is the difference between RC0402FR-07102KL and CR0402-FX-1023GLF?

A: Both are direct equivalents with identical electrical and mechanical specifications. The primary difference is manufacturer: RC0402FR-07102KL is manufactured by YAGEO and includes moisture-resistant construction, while CR0402-FX-1023GLF is manufactured by Bourns Inc. without specified moisture-resistant features. Selection depends on supply availability and moisture-resistant requirement.

Q: When should ERJ-2RKF1023X be selected instead of the original part?

A: ERJ-2RKF1023X provides a higher power rating (0.1W versus 0.063W) and includes AEC-Q200 automotive qualification. Select this part when the application requires automotive-grade reliability, higher thermal margin, or when operating conditions approach the power dissipation limits of the original 1/16W rating.

Q: Are AEC-Q200 qualified parts (AC0402FR-07102KL, CRCW0402102KFKED, RMCF0402FT102K) suitable for non-automotive applications?

A: Yes. AEC-Q200 qualification represents enhanced reliability testing and quality standards. These parts are fully compatible with non-automotive applications and may be selected for designs requiring higher reliability assurance or when automotive-qualified inventory is available.

Q: Why is CRCW0402102KFKTD listed as a substitute if it is RoHS non-compliant?

A: CRCW0402102KFKTD is electrically and mechanically equivalent but carries RoHS non-compliant and REACH Affected status. This part is included for reference only and is restricted to applications not subject to RoHS3 or REACH regulatory requirements. For new designs and regulated applications, CRCW0402102KFKED (ROHS3 compliant variant) is the appropriate selection.

Q: Can substitute parts be mixed in the same assembly?

A: All listed direct and upgrade substitutes are mechanically and electrically compatible for mixed use within the same assembly. However, design documentation and bill of materials should specify the selected part number to maintain traceability and ensure consistent procurement.

Q: What is the significance of moisture-resistant construction in RC1005F1023CS and RC0402FR-07102KL?

A: Moisture-resistant thick film construction provides enhanced reliability in humid environments and applications with exposure to moisture or condensation. This feature is specified in the original RC1005F1023CS and is matched in RC0402FR-07102KL. For applications in standard dry environments, non-moisture-resistant equivalents (CR0402-FX-1023GLF) are functionally equivalent.

Q: Are all substitute parts available in Tape & Reel (TR) packaging?

A: Most substitutes are available in Tape & Reel packaging. RC0402FR-07102KL is available in Cut Tape (CT) & Digi-Reel® packaging. Verify packaging format with supplier documentation to ensure compatibility with assembly equipment and procurement requirements.
