Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RP104PJ100CS is determined by the following mandatory parameters:

Primary Matching Criteria:

• Resistance value: 10 Ohm
• Tolerance: ±5%
• Number of resistors: 4
• Circuit type: Isolated
• Package format: 0804 with convex, long side terminals
• Number of pins: 8
• Temperature coefficient: ±200ppm/°C
• Mounting type: Surface Mount

Secondary Compatibility Factors:

• Power per element rating (minimum 62.5mW)
• Operating temperature range (minimum -55°C to 125°C)
• RoHS3 compliance
• MSL rating of 1

Two substitute parts meet these criteria and are listed below.

Parameter Comparison

Engineering Selection Recommendations

741X083100JP (CTS Resistor Products) is the primary substitute for RP104PJ100CS. This part maintains full electrical equivalence across all critical parameters including resistance, tolerance, temperature coefficient, and power rating. The CTS part is currently in active production status with substantial inventory availability (46,967 units). The operating temperature range of -55°C to 125°C covers standard industrial applications, though it does not extend to the upper 155°C limit of the Samsung part. Height-seated dimension is 0.022" (0.55mm) compared to 0.018" (0.45mm) for the Samsung part, which may require PCB layout verification in space-constrained applications. Both parts carry ROHS3 compliance and MSL rating of 1.

MNR04MRAPJ100 (Rohm Semiconductor) provides an alternative substitute with identical electrical specifications and operating temperature range matching the Samsung part (-55°C to 155°C). However, this part is discontinued at DiGi Electronics, limiting long-term supply viability. Current inventory is limited to 1,148 units. This part should be considered only when the extended upper temperature rating is a critical requirement and supply chain continuity is not a concern.

For new designs and ongoing production, CTS 741X083100JP is the recommended substitute due to active production status and superior inventory levels.

Frequently Asked Questions (FAQ)

Q: Can 741X083100JP directly replace RP104PJ100CS in existing designs?

A: Yes, 741X083100JP is electrically and mechanically equivalent for all core specifications. Both parts feature 10 Ohm ±5% resistance, 4-element isolated configuration, 8-pin 0804 package, and ±200ppm/°C temperature coefficient. The primary consideration is the operating temperature range: CTS part is rated to 125°C maximum versus Samsung's 155°C. If your application operates below 125°C, substitution is direct. If sustained operation above 125°C is required, the Samsung part or Rohm MNR04MRAPJ100 should be retained.

Q: What is the height difference between these parts, and does it matter?

A: Samsung RP104PJ100CS has a seated height of 0.018" (0.45mm), while CTS 741X083100JP measures 0.022" (0.55mm), and Rohm MNR04MRAPJ100 measures 0.020" (0.50mm). The 0.004" to 0.007" difference is negligible for most PCB layouts. However, in applications with tight vertical clearance constraints or automated assembly with height-sensitive fixtures, this variation should be verified against your specific design requirements.

Q: Are all three parts RoHS3 compliant?

A: Yes. RP104PJ100CS, 741X083100JP, and MNR04MRAPJ100 are all ROHS3 compliant with MSL rating of 1 (unlimited moisture sensitivity). All parts are suitable for applications requiring environmental compliance certification.

Q: Why is MNR04MRAPJ100 marked as discontinued?

A: MNR04MRAPJ100 is discontinued at DiGi Electronics, indicating that this distributor no longer actively stocks or supports this part. However, limited inventory (1,148 units) remains available. For new production programs, this part should not be selected due to supply uncertainty. It may be considered only as a temporary solution when the extended temperature rating (-55°C to 155°C) is mandatory and alternative sources can be secured.

Q: What packaging formats are available for these substitutes?

A: RP104PJ100CS is available in standard packaging (format not specified in data). CTS 741X083100JP is supplied in Tape & Reel (TR) format. Rohm MNR04MRAPJ100 is available in Cut Tape (CT) and Digi-Reel® formats. Packaging selection should align with your assembly process requirements and volume commitments.

Q: Can I use these parts interchangeably in automotive applications?

A: CTS 741X083100JP is qualified for automotive AEC-Q200 applications, making it suitable for automotive designs. Samsung RP104PJ100CS and Rohm MNR04MRAPJ100 do not list automotive qualification in the provided specifications. If AEC-Q200 compliance is required, CTS 741X083100JP is the appropriate choice.
