Substitute Part Grouping Explanation

Substitute parts for the RC1005F112CS are classified into three categories based on electrical and mechanical compatibility:

Direct Equivalents share identical electrical specifications (1.1 kOhms ±1%, 0.063W, ±100ppm/°C) and mechanical dimensions (0402 package, 1.00mm x 0.50mm). These parts are interchangeable without circuit redesign:

• CR0402-FX-1101GLF (Bourns Inc.)
• CRG0402F1K1 (TE Connectivity Passive Product)
• RC0402FR-071K1L (YAGEO)

Upgrade Option maintains electrical specifications but increases power rating to 0.1W (1/10W) and adds automotive AEC-Q200 qualification:

• ERJ-2RKF1101X (Panasonic Electronic Components)

Similar Parts match all electrical and mechanical specifications but include additional automotive AEC-Q200 qualification or alternative packaging:

• AC0402FR-071K1L (YAGEO)
• CRCW04021K10FKED (Vishay Dale)
• RMCF0402FT1K10 (Stackpole Electronics Inc)

Substitution is determined by matching: resistance value, tolerance, power rating, package dimensions, temperature coefficient, and operating temperature range.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement: CR0402-FX-1101GLF, CRG0402F1K1, and RC0402FR-071K1L provide full electrical and mechanical equivalence to RC1005F112CS. All three maintain identical resistance, tolerance, power rating, and temperature specifications. RC0402FR-071K1L from YAGEO offers the highest inventory availability (570,100 pcs) and includes moisture resistant construction matching the original part.

For Automotive Applications: AC0402FR-071K1L, CRCW04021K10FKED, and RMCF0402FT1K10 are qualified to AEC-Q200 automotive standards while maintaining full electrical compatibility. These parts are suitable for automotive-grade circuit designs requiring enhanced reliability qualification.

For Increased Power Margin: ERJ-2RKF1101X from Panasonic provides upgraded 0.1W (1/10W) power rating with AEC-Q200 qualification. This option is applicable when circuit design permits higher power dissipation capacity or when automotive qualification is required.

All substitute parts are ROHS3 compliant, MSL 1 rated, and operate across the full -55°C to 155°C temperature range. Selection should be based on packaging format requirements (Tape & Reel vs. Cut Tape), inventory availability, and application-specific certifications.

Frequently Asked Questions (FAQ)

Q: Can CR0402-FX-1101GLF replace RC1005F112CS directly in production?

A: Yes. CR0402-FX-1101GLF is a direct equivalent with identical electrical specifications (1.1 kOhms ±1%, 0.063W) and 0402 package dimensions. No circuit redesign is required.

Q: What is the difference between the direct equivalents and the AEC-Q200 qualified parts?

A: Direct equivalents (CR0402-FX-1101GLF, CRG0402F1K1, RC0402FR-071K1L) match all electrical and mechanical specifications. AEC-Q200 qualified parts (AC0402FR-071K1L, CRCW04021K10FKED, RMCF0402FT1K10) add automotive reliability qualification but maintain identical electrical performance. Selection depends on application requirements.

Q: Is ERJ-2RKF1101X compatible with circuits designed for RC1005F112CS?

A: ERJ-2RKF1101X is electrically compatible with identical resistance, tolerance, and temperature coefficient. The increased power rating (0.1W vs. 0.063W) is a design upgrade that does not affect compatibility. Physical dimensions remain identical at 0402 package.

Q: Does packaging format (Tape & Reel vs. Cut Tape) affect electrical performance?

A: No. Packaging format affects only handling and assembly processes. Electrical specifications and performance are identical regardless of packaging type. Selection should be based on manufacturing equipment compatibility and supply chain requirements.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating, matching the original RC1005F112CS specifications.

Q: Which substitute part has the highest inventory availability?

A: RC0402FR-071K1L from YAGEO has 570,100 pcs in stock, significantly higher than other alternatives. This part also includes moisture resistant construction matching the original specification.
