Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RC1005F3832CS are classified based on strict electrical and mechanical parameter alignment. The primary substitution criteria are:

Critical Parameters (Must Match Exactly):

• Resistance value: 38.3 kOhms
• Tolerance: ±1%
• Package: 0402 (1005 Metric)
• Composition: Thick Film
• Temperature Coefficient: ±100ppm/°C
• Operating Temperature Range: -55°C ~ 155°C
• Terminations: 2
• RoHS3 Compliance

Secondary Parameters (Allowable Variation):

• Power Rating: 0.063W (1/16W) baseline; 0.1W (1/10W) represents an upgrade
• Features: Moisture Resistant designation is optional; Automotive AEC-Q200 qualification is optional enhancement
• Height - Seated: Tolerance within 0.016" (0.40mm) maximum

All substitute parts listed maintain identical resistance, tolerance, package format, and temperature specifications. Variations in power rating and automotive qualification represent either direct equivalents or performance upgrades suitable for the same circuit applications.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalents (Identical Specifications):

CR0402-FX-3832GLF (Bourns Inc.) and RC0402FR-0738K3L (YAGEO) function as direct electrical and mechanical equivalents to the RC1005F3832CS. Both maintain identical resistance, tolerance, power rating, package dimensions, and temperature characteristics. Selection between these options depends on supply chain availability and inventory requirements.

Enhanced Specification Options:

ERJ-2RKF3832X (Panasonic Electronic Components) provides a power rating upgrade from 0.063W to 0.1W while maintaining all other critical parameters. This part is qualified to Automotive AEC-Q200 standard and is suitable for applications requiring higher thermal margin or automotive-grade reliability.

AC0402FR-0738K3L (YAGEO), CRCW040238K3FKED (Vishay Dale), and RMCF0402FT38K3 (Stackpole Electronics Inc) combine moisture resistant characteristics with Automotive AEC-Q200 qualification. These parts are appropriate for applications in automotive, industrial, or high-reliability environments where enhanced qualification standards are specified.

All substitute parts maintain RoHS3 compliance, MSL Level 1 rating, and identical operating temperature range (-55°C ~ 155°C). Selection should be based on application requirements, supply chain strategy, and any specific automotive or industrial qualification mandates.

Frequently Asked Questions (FAQ)

Q: Can CR0402-FX-3832GLF replace RC1005F3832CS in any circuit application?

A: Yes. CR0402-FX-3832GLF is a direct equivalent with identical electrical specifications (38.3 kOhms ±1%, 0.063W, ±100ppm/°C) and mechanical package (0402). Both parts are RoHS3 compliant with MSL Level 1 rating. The only difference is manufacturer and lack of explicit moisture resistant designation on the Bourns part, which does not affect functionality in standard applications.

Q: What is the difference between the 0.063W and 0.1W power-rated versions?

A: ERJ-2RKF3832X is rated at 0.1W (1/10W) compared to the 0.063W (1/16W) baseline. The higher power rating provides greater thermal dissipation capability and margin in high-current applications. All other electrical parameters remain identical. The 0.1W version is suitable as a direct replacement in any circuit designed for 0.063W, with the benefit of improved thermal performance.

Q: Are the automotive AEC-Q200 qualified parts interchangeable with non-automotive versions?

A: Yes. AC0402FR-0738K3L, CRCW040238K3FKED, and RMCF0402FT38K3 are automotive-qualified versions with identical electrical and mechanical specifications to the base RC1005F3832CS. Automotive qualification represents an additional quality and reliability standard and does not restrict use in non-automotive applications. These parts are direct substitutes with enhanced qualification credentials.

Q: Does the 0402 package dimension vary between manufacturers?

A: No. All listed substitute parts conform to the 0402 (1005 Metric) package standard with dimensions of 0.039" L x 0.020" W (1.00mm x 0.50mm). Height - Seated specifications are within 0.016" (0.40mm) maximum across all parts, with AC0402FR-0738K3L specified at 0.015" (0.37mm). These minor height variations are within standard PCB assembly tolerances and do not affect interchangeability.

Q: What does MSL Level 1 (Unlimited) mean for moisture sensitivity?

A: MSL Level 1 indicates the component has unlimited shelf life and requires no special moisture control during storage or handling. This classification applies to all listed parts and means they can be stored in standard warehouse conditions without desiccant packaging or time-limited exposure windows.

Q: Can I use RC0402FR-0738K3L as a substitute if moisture resistance is required?

A: Yes. RC0402FR-0738K3L is explicitly designated as moisture resistant, matching the moisture resistant feature of the RC1005F3832CS. This part is manufactured by YAGEO and maintains identical electrical specifications with 777,972 units in stock, providing excellent supply availability.
