Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RC1005F1542CS are classified based on strict electrical and mechanical parameter alignment. The primary substitution criteria are:

Critical Parameters (Must Match):

• Resistance value: 15.4 kOhms
• Tolerance: ±1%
• Package / Case: 0402 (1005 Metric)
• Composition: Thick Film
• Temperature Coefficient: ±100ppm/°C
• Operating Temperature Range: -55°C ~ 155°C
• Number of Terminations: 2
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Secondary Parameters (Allowable Variation):

• Power Rating: 0.063W (1/16W) is standard; 0.1W (1/10W) represents an upgrade with enhanced thermal capability
• Features: Moisture resistance is standard; automotive AEC-Q200 qualification is an enhancement
• Height - Seated (Max): Nominal 0.016" (0.40mm); minor variations (0.015" / 0.37mm) are acceptable within package specification

Substitution Categories:

Direct Equivalents: Parts with identical electrical specifications, packaging, and power rating (CR0402-FX-1542GLF, RC0402FR-0715K4L, CRCW040215K4FKED, AC0402FR-0715K4L, RMCF0402FT15K4)

Upgrade Substitute: Part with higher power rating (ERJ-2RKF1542X at 0.1W) providing enhanced thermal performance while maintaining all other critical parameters

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent Selection:

CR0402-FX-1542GLF (Bourns Inc.), RC0402FR-0715K4L (YAGEO), CRCW040215K4FKED (Vishay Dale), AC0402FR-0715K4L (YAGEO), and RMCF0402FT15K4 (Stackpole Electronics Inc) are functionally equivalent to the RC1005F1542CS. All maintain identical resistance, tolerance, power rating, package format, temperature coefficient, and operating temperature range. All are ROHS3 compliant with MSL 1 rating. These parts are suitable for direct substitution in applications where the original specification is maintained.

Upgrade Substitute Selection:

ERJ-2RKF1542X (Panasonic Electronic Components) provides enhanced thermal capability at 0.1W (1/10W) power rating compared to the standard 0.063W (1/16W). This upgrade maintains all critical electrical parameters including resistance, tolerance, temperature coefficient, and operating temperature range. The part includes automotive AEC-Q200 qualification. Selection of this upgrade is appropriate for applications requiring higher power dissipation margin or automotive-grade reliability.

Automotive Application Consideration:

For applications requiring automotive qualification, AC0402FR-0715K4L, CRCW040215K4FKED, and RMCF0402FT15K4 carry AEC-Q200 certification while maintaining the standard 0.063W power rating. ERJ-2RKF1542X also provides AEC-Q200 qualification with enhanced power rating.

Inventory and Availability:

RC0402FR-0715K4L (YAGEO) offers the highest inventory availability at 438,270 pieces. ERJ-2RKF1542X (Panasonic) provides 137,624 pieces. RMCF0402FT15K4 (Stackpole) stocks 227,795 pieces. CR0402-FX-1542GLF (Bourns) maintains 45,828 pieces. AC0402FR-0715K4L (YAGEO) has 13,527 pieces available.

Frequently Asked Questions (FAQ)

Q: Can CR0402-FX-1542GLF replace RC1005F1542CS in all applications?

A: CR0402-FX-1542GLF is a direct electrical and mechanical equivalent with identical resistance (15.4 kOhms), tolerance (±1%), power rating (0.063W), package (0402), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C ~ 155°C).
