Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RC1005F2552CS are classified based on strict electrical and mechanical parameter matching. All identified substitutes maintain the following core specifications: 25.5 kOhms resistance value, ±1% tolerance, 0402 (1005 Metric) package dimensions, thick film composition, ±100ppm/°C temperature coefficient, and -55°C to 155°C operating temperature range. Substitutes are grouped into three categories:

Direct Equivalents share identical power ratings (0.063W), packaging format (Tape & Reel), and moisture-resistant or standard thick film construction without automotive qualification.

Upgrade Substitutes provide enhanced power rating (0.1W instead of 0.063W) while maintaining all other electrical parameters, suitable for applications requiring higher thermal margin.

Similar Substitutes include automotive-grade (AEC-Q200) variants with identical or equivalent electrical specifications, offering enhanced reliability for automotive and industrial applications.

All substitutes are ROHS3 compliant, feature MSL 1 rating, and operate within the specified temperature range. Substitution compatibility is determined exclusively by these provided parameters.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement in ROHS3-Compliant Applications: CR0402-FX-2552GLF (Bourns Inc.) and RC0402FR-0725K5L (YAGEO) are direct functional equivalents with identical electrical and mechanical specifications. RC0402FR-0725K5L includes moisture-resistant construction matching the original part. Both maintain ROHS3 compliance and standard Tape & Reel packaging.

For Enhanced Thermal Performance: ERJ-2RKF2552X (Panasonic Electronic Components) provides upgraded 0.1W power rating while maintaining all other electrical parameters. This part is suitable for applications requiring higher power dissipation margin and includes Automotive AEC-Q200 qualification with ROHS3 compliance.

For Automotive and Industrial Applications: AC0402FR-0725L (YAGEO), CRCW040225K5FKED (Vishay Dale), and RMCF0402FT25K5 (Stackpole Electronics Inc) are AEC-Q200 qualified alternatives with ROHS3 compliance. AC0402FR-0725K5L additionally includes moisture-resistant construction. These parts are suitable for automotive-grade circuit designs requiring enhanced reliability certification.

Not Recommended for New Designs: CRCW040225K5FKTD (Vishay Dale) is RoHS non-compliant and REACH-affected, making it unsuitable for applications requiring regulatory compliance with current environmental standards.

Frequently Asked Questions (FAQ)

Q: Can CR0402-FX-2552GLF replace RC1005F2552CS directly in production? A: Yes. CR0402-FX-2552GLF is a direct equivalent with matching 25.5 kOhms resistance, ±1% tolerance, 0.063W power rating, 0402 package, and ROHS3 compliance. The only difference is standard (non-moisture-resistant) thick film construction versus moisture-resistant construction in the original part.

Q: What is the difference between the main part and ERJ-2RKF2552X? A: ERJ-2RKF2552X provides higher power rating (0.1W versus 0.063W) while maintaining identical resistance, tolerance, package, and temperature specifications. This upgrade is suitable for applications requiring additional thermal margin. Both parts are ROHS3 compliant and operate within -55°C to 155°C.

Q: Are automotive-grade substitutes (AEC-Q200) compatible with consumer electronics applications? A: Yes. AEC-Q200 qualified parts such as AC0402FR-0725K5L, CRCW040225K5FKED, and RMCF0402FT25K5 meet or exceed the electrical and environmental specifications of the original RC1005F2552CS. These parts are suitable for any application within the specified operating temperature and power rating ranges.

Q: Why is CRCW040225K5FKTD not recommended? A: CRCW040225K5FKTD is RoHS non-compliant and REACH-affected, failing to meet current environmental and regulatory requirements. Applications requiring ROHS3 compliance should use alternative substitutes.

Q: Does packaging format (Tape & Reel versus Cut Tape) affect electrical performance? A: No. Packaging format affects only handling, storage, and assembly processes. RC0402FR-0725K5L is supplied in Cut Tape & Digi-Reel format while maintaining identical electrical specifications and performance characteristics to Tape & Reel packaged alternatives.

Q: Can I use RMCF0402FT25K5 in moisture-sensitive applications? A: RMCF0402FT25K5 has MSL 1 (Unlimited) rating, identical to the original part. However, it does not include moisture-resistant construction features. For applications requiring moisture-resistant thick film construction, use RC0402FR-0725K5L or AC0402FR-0725K5L.

Q: What is the height difference between AC0402FR-0725K5L and other substitutes? A: AC0402FR-0725K5L has maximum seated height of 0.015" (0.37mm) compared to 0.016" (0.40mm) for most other substitutes. This 0.01mm difference is within standard PCB assembly tolerances and does not affect functional compatibility.
