Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC1005J155CS is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 1.5 MOhms (exact match required)
• Package / Case: 0402 (1005 Metric) (exact match required)
• Power rating: 0.063W minimum (equal or higher acceptable)
• Composition: Thick Film
• Operating temperature range: -55°C ~ 155°C minimum (equal or wider acceptable)
• RoHS compliance: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Allowable Variation Parameters:

• Tolerance: ±5% or tighter (±1% acceptable as upgrade)
• Temperature coefficient: ±100ppm/°C or ±200ppm/°C (both acceptable)
• Packaging format: Tape & Reel (TR) or Cut Tape (CT) & Digi-Reel® (both acceptable)
• Features: Moisture Resistant or Automotive AEC-Q200 (both acceptable)

Substitute parts are grouped into Direct Equivalents and Upgrade options based on tolerance specification and automotive qualification status.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent Selection:

RC0402JR-071M5L (YAGEO) is the primary direct equivalent to RC1005J155CS. This part matches all mandatory electrical and mechanical parameters with identical tolerance (±5%), temperature coefficient (±100ppm/°C), and operating range. Both components are Active in product status with ROHS3 compliance and MSL 1 rating. YAGEO RC0402JR-071M5L offers significantly higher inventory availability (119,179 pieces) compared to the Samsung part, making it suitable for high-volume production requirements.

Upgrade Selection for Enhanced Tolerance:

RMCF0402FT1M50 (Stackpole Electronics Inc) provides an upgrade path with tighter tolerance specification (±1% versus ±5%). This part maintains all other critical parameters while adding Automotive AEC-Q200 qualification. The temperature coefficient increases to ±200ppm/°C, which remains within acceptable operational limits for most applications. This component is Active in product status with robust inventory (72,326 pieces) and is suitable for applications requiring improved accuracy or automotive-grade reliability.

Upgrade Selection for Automotive Applications:

RMCF0402JT1M50 (Stackpole Electronics Inc) maintains the original ±5% tolerance while providing Automotive AEC-Q200 qualification and ±200ppm/°C temperature coefficient. This part is appropriate for automotive or industrial applications requiring AEC-Q200 compliance without tolerance tightening. Product status is Active with 8,487 pieces in inventory.

Discontinued Part Consideration:

MCR01MRTJ155 (Rohm Semiconductor) is marked as Discontinued at DiGi Electronics and should not be selected for new designs or long-term production commitments despite current inventory availability.

Frequently Asked Questions (FAQ)

Q: Can RC0402JR-071M5L be used as a direct replacement for RC1005J155CS?

A: Yes. RC0402JR-071M5L is a direct equivalent. Both parts share identical resistance (1.5 MOhms), tolerance (±5%), power rating (0.063W), package (0402), composition (Thick Film), temperature range (-55°C ~ 155°C), and compliance certifications (ROHS3, MSL 1). The primary difference is manufacturer (YAGEO versus Samsung) and significantly higher inventory availability.

Q: What is the difference between RMCF0402FT1M50 and RMCF0402JT1M50?

A: Both parts are manufactured by Stackpole Electronics Inc in 0402 package with Automotive AEC-Q200 qualification. The primary difference is tolerance: RMCF0402FT1M50 specifies ±1% tolerance while RMCF0402JT1M50 specifies ±5% tolerance. Both have identical temperature coefficient (±200ppm/°C) and operating range (-55°C ~ 155°C). Selection depends on circuit accuracy requirements.

Q: Is the ±200ppm/°C temperature coefficient of Stackpole parts acceptable as a substitute?

A: Yes. The RC1005J155CS specifies ±100ppm/°C while Stackpole RMCF series parts specify ±200ppm/°C. Both values are within acceptable operational limits for thick film chip resistor applications. The higher temperature coefficient of Stackpole parts represents a measurable but acceptable variation for most circuit designs. Verify compatibility with specific circuit requirements if temperature stability is critical.

Q: Can I use Cut Tape (CT) & Digi-Reel® packaging instead of Tape & Reel (TR)?

A: Yes. Both packaging formats are acceptable for component substitution. Cut Tape and Digi-Reel® packaging is suitable for lower-volume applications or manual assembly processes, while Tape & Reel is standard for automated pick-and-place assembly. Packaging selection depends on manufacturing process requirements rather than electrical compatibility.

Q: Why should MCR01MRTJ155 be avoided despite inventory availability?

A: MCR01MRTJ155 is marked as Discontinued at DiGi Electronics. Using discontinued parts in new designs creates supply chain risk and limits future procurement options. Active parts such as RC0402JR-071M5L, RMCF0402FT1M50, and RMCF0402JT1M50 are recommended for new designs and production commitments.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts (RC0402JR-071M5L, MCR01MRTJ155, RMCF0402FT1M50, RMCF0402JT1M50) are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating, matching the compliance profile of RC1005J155CS.

Q: What inventory considerations should guide part selection?

A: RC0402JR-071M5L (YAGEO) offers the highest inventory availability at 119,179 pieces, followed by RMCF0402FT1M50 (Stackpole) at 72,326 pieces. For high-volume production, YAGEO RC0402JR-071M5L provides supply security. For automotive applications requiring AEC-Q200 qualification, Stackpole parts offer adequate inventory with enhanced reliability ratings.
