Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RC1005F2373CS are classified based on strict electrical and mechanical parameter alignment. All substitute candidates maintain identical resistance value (237 kOhms), tolerance (±1%), package format (0402 / 1005 Metric), composition (thick film), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C ~ 155°C). The primary substitution criteria are:

Direct Equivalents maintain all specifications including power rating (0.063W), moisture resistance features, and packaging format (Cut Tape or Tape & Reel).

Upgrade Substitutes feature enhanced power rating (0.1W instead of 0.063W) or automotive-grade certifications (AEC-Q200) while maintaining all other core electrical parameters.

Similar Substitutes include automotive-qualified variants or alternative packaging options that preserve electrical performance and mechanical compatibility.

All substitute parts are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with HTSUS code 8533.21.0030, matching the regulatory profile of the main part.

Parameter Comparison

Engineering Selection Recommendations

Direct Substitution (Identical Specifications): CR0402-FX-2373GLF (Bourns Inc.) and RC0402FR-07237KL (YAGEO) are direct electrical equivalents with matching 237 kOhms resistance, ±1% tolerance, 0.063W power rating, and 0402 package format. Both maintain ROHS3 compliance and MSL 1 rating. Selection between these and the main part depends on packaging preference (Cut Tape versus Tape & Reel) and supplier availability. RC0402FR-07237KL includes moisture resistant features matching the original specification.

Upgrade Substitution (Enhanced Power Rating): ERJ-2RKF2373X (Panasonic Electronic Components) provides increased power dissipation capability at 0.1W (1/10W) while maintaining all other electrical parameters. This upgrade is suitable for applications requiring thermal margin or higher power handling without circuit redesign. The part includes automotive AEC-Q200 qualification.

Automotive-Grade Substitution (AEC-Q200 Certified): AC0402FR-07237KL (YAGEO), CRCW0402237KFKED (Vishay Dale), and RMCF0402FT237K (Stackpole Electronics Inc) are automotive-qualified alternatives with AEC-Q200 certification. These parts are suitable for automotive and industrial applications requiring enhanced reliability standards. AC0402FR-07237KL additionally includes moisture resistant construction. All three maintain 0.063W power rating and 0402 package compatibility.

All substitute parts are Active status products with ROHS3 compliance, REACH unaffected status, and identical regulatory classification (ECCN EAR99, HTSUS 8533.21.0030).

Frequently Asked Questions (FAQ)

Q: Can CR0402-FX-2373GLF replace RC1005F2373CS in existing designs? A: Yes. CR0402-FX-2373GLF is a direct electrical equivalent with identical 237 kOhms resistance, ±1% tolerance, 0.063W power rating, and 0402 package dimensions. The primary difference is packaging format (Tape & Reel versus Cut Tape). Mechanical fit and electrical performance are equivalent.

Q: What is the difference between the main part and ERJ-2RKF2373X? A: ERJ-2RKF2373X features a higher power rating of 0.1W (1/10W) compared to the 0.063W (1/16W) rating of RC1005F2373CS. All other electrical parameters—resistance, tolerance, temperature coefficient, and operating range—are identical. The upgrade provides thermal margin for applications with higher power dissipation requirements. Both use 0402 package format.

Q: Are automotive-grade substitutes compatible with non-automotive applications? A: Yes. Automotive-grade parts (AC0402FR-07237KL, CRCW0402237KFKED, RMCF0402FT237K) with AEC-Q200 certification meet or exceed commercial-grade specifications. These parts are fully compatible with non-automotive applications and provide enhanced reliability margins.

Q: Does moisture resistance affect substitution compatibility? A: Moisture resistance is a feature enhancement. RC0402FR-07237KL and AC0402FR-07237KL include moisture resistant construction matching the original RC1005F2373CS specification. Parts without this feature (CR0402-FX-2373GLF) are still electrically equivalent but lack this environmental protection. Selection depends on application moisture exposure requirements.

Q: What packaging options are available for substitutes? A: The main part RC1005F2373CS is supplied in Cut Tape (CT) format. Substitute parts are available in Tape & Reel (TR) format (CR0402-FX-2373GLF, ERJ-2RKF2373X, AC0402FR-07237KL, CRCW0402237KFKED, RMCF0402FT237K) or Cut Tape & Digi-Reel® format (RC0402FR-07237KL). Packaging format does not affect electrical or mechanical compatibility; selection is based on assembly process requirements.

Q: Are all substitute parts ROHS3 compliant? A: Yes. All listed substitute parts maintain ROHS3 compliance, REACH unaffected status, and identical regulatory classification (ECCN EAR99, HTSUS 8533.21.0030) as the main part RC1005F2373CS.

Q: Can I use RMCF0402FT237K as a direct replacement? A: Yes. RMCF0402FT237K (Stackpole Electronics Inc) is a direct electrical equivalent with 237 kOhms resistance, ±1% tolerance, 0.063W power rating, and 0402 package format. It includes automotive AEC-Q200 qualification and is supplied in Tape & Reel format. Electrical performance and mechanical fit are equivalent to the original part.
