Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC1005J305CS is determined by the following critical parameters:

Primary Substitution Criteria:

• Resistance value: 3 MOhms (exact match required)
• Package / Case: 0402 (1005 Metric) (exact match required)
• Power rating: 0.063W minimum (1/16W)
• Tolerance: ±5% or better (±1% is acceptable as upgrade)
• Operating temperature range: -55°C to 155°C minimum
• Composition: Thick Film
• Moisture Sensitivity Level: 1 (Unlimited)
• RoHS3 Compliance: Required

Secondary Considerations:

• Temperature coefficient variation (±100ppm/°C to ±200ppm/°C acceptable)
• Packaging format (Tape & Reel or Cut Tape both acceptable)
• Manufacturer availability and inventory levels
• Product status (Active preferred; Discontinued acceptable if in stock)

All substitute parts listed meet or exceed the primary substitution criteria. Parts with improved tolerance (±1%) or automotive qualification (AEC-Q200) are classified as upgrades while maintaining full compatibility.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent (Same Specifications):

RC0402JR-073ML (YAGEO) is the primary direct equivalent to RC1005J305CS. Both parts share identical electrical specifications including 3 MOhms resistance, ±5% tolerance, ±100ppm/°C temperature coefficient, and 0.063W power rating. YAGEO maintains significantly higher inventory (368,941 pieces) with Active product status, making this the preferred substitute for standard applications requiring immediate availability.

Specification-Compatible Alternatives:

MCR01MRTJ305 (Rohm Semiconductor) meets all substitution criteria with identical resistance, tolerance, and power rating. However, this part is Discontinued at DiGi Electronics with limited inventory (7,756 pieces) and exhibits a higher temperature coefficient of ±200ppm/°C. Selection of this part is appropriate only when existing inventory must be cleared or when Rohm-specific supply chain requirements apply.

Upgraded Specifications (Higher Tolerance Precision):

RMCF0402FT3M00 (Stackpole Electronics Inc) provides enhanced tolerance of ±1% compared to the ±5% specification of RC1005J305CS, while maintaining all other electrical and mechanical parameters. This part carries AEC-Q200 automotive qualification and is suitable for applications requiring tighter resistance tolerance. Temperature coefficient is ±200ppm/°C. Inventory availability is excellent (387,609 pieces) with Active product status.

Upgraded Specifications (Automotive Grade, Standard Tolerance):

RMCF0402JT3M00 (Stackpole Electronics Inc) maintains the ±5% tolerance of the original part while adding AEC-Q200 automotive qualification. Temperature coefficient is ±200ppm/°C. This part is appropriate for automotive or industrial applications requiring AEC-Q200 compliance. Inventory is available (20,783 pieces) with Active product status.

All substitute parts are ROHS3 Compliant, REACH Unaffected, and maintain MSL 1 (Unlimited) moisture sensitivity rating, ensuring regulatory and environmental compliance equivalent to the original part.

Frequently Asked Questions (FAQ)

Q: Can RC0402JR-073ML (YAGEO) be used as a direct replacement for RC1005J305CS (Samsung)?

A: Yes. RC0402JR-073ML is a direct equivalent. Both parts share identical electrical specifications: 3 MOhms ±5%, 0.063W power rating, ±100ppm/°C temperature coefficient, and -55°C to 155°C operating range. Both are packaged in 0402 (1005 Metric) format with MSL 1 rating and ROHS3 compliance. The parts are mechanically and electrically interchangeable.

Q: What is the difference between the Stackpole RMCF0402FT3M00 and RMCF0402JT3M00 parts?

A: The primary difference is tolerance specification. RMCF0402FT3M00 provides ±1% tolerance (tighter precision), while RMCF0402JT3M00 provides ±5% tolerance (matching the original RC1005J305CS). Both parts share identical power rating (0.063W), temperature coefficient (±200ppm/°C), operating range (-55°C to 155°C), package format (0402), and AEC-Q200 automotive qualification. Selection depends on tolerance requirements of the specific application.

Q: Why does MCR01MRTJ305 show "Discontinued at DiGi Electronics" status?

A: MCR01MRTJ305 is marked as Discontinued at DiGi Electronics, indicating this distributor no longer actively stocks or supports this part. However, 7,756 pieces remain in inventory. This part remains functionally equivalent to RC1005J305CS and may be selected if existing stock must be utilized or if alternative supply channels are available. For new designs, RC0402JR-073ML or Stackpole alternatives are preferred due to Active status.

Q: Are the Stackpole RMCF series parts suitable for automotive applications?

A: Yes. Both RMCF0402FT3M00 and RMCF0402JT3M00 carry AEC-Q200 automotive qualification, making them suitable for automotive and industrial applications requiring this certification. The original RC1005J305CS does not carry automotive qualification. Selection of Stackpole parts is appropriate when AEC-Q200 compliance is a design requirement.

Q: What is the significance of the temperature coefficient difference (±100ppm/°C vs ±200ppm/°C)?

A: Temperature coefficient indicates how much the resistance value changes per degree Celsius of temperature change. RC1005J305CS and RC0402JR-073ML both specify ±100ppm/°C, while MCR01MRTJ305 and both Stackpole parts specify ±200ppm/°C. The lower coefficient (±100ppm/°C) indicates better temperature stability. For applications with strict temperature stability requirements, RC0402JR-073ML is preferred. For general applications, ±200ppm/°C is acceptable within the -55°C to 155°C operating range.

Q: Can packaging format (Tape & Reel vs Cut Tape) affect substitution decisions?

A: Packaging format does not affect electrical or mechanical compatibility. RC1005J305CS and Stackpole parts are supplied in Tape & Reel (TR) format, while RC0402JR-073ML and MCR01MRTJ305 are supplied in Cut Tape (CT) & Digi-Reel® format. Selection between formats depends on assembly equipment compatibility and procurement preferences, not component functionality.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts (RC0402JR-073ML, MCR01MRTJ305, RMCF0402FT3M00, RMCF0402JT3M00) are ROHS3 Compliant and REACH Unaffected, matching the compliance status of RC1005J305CS. All parts maintain MSL 1 (Unlimited) moisture sensitivity rating.
