RP104PJ270CS Equivalent & Substitute Parts Reference

Part Overview

The RP104PJ270CS is a 27 Ohm isolated 4-resistor network array manufactured by Samsung Electro-Mechanics. This surface-mount component features 62.5mW power per element with ±5% tolerance and ±200ppm/°C temperature coefficient. The part is classified as Active status with full RoHS3 compliance and unlimited moisture sensitivity rating. Substitute parts are necessary when Samsung Electro-Mechanics inventory becomes unavailable or when alternative manufacturers offer equivalent electrical and mechanical specifications for the 0804 package configuration.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RP104PJ270CS is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 27 Ohm
• Tolerance: ±5%
• Number of resistors: 4
• Circuit type: Isolated
• Power per element: 62.5mW
• Number of pins: 8
• Package / Case: 0804, Convex, Long Side Terminals
• Mounting type: Surface Mount
• RoHS3 compliance
• MSL rating: 1 (Unlimited)

Allowable Variation Parameters:

• Temperature coefficient: ±200ppm/°C to ±300ppm/°C (within acceptable drift range)
• Operating temperature range: -55°C ~ 125°C to -55°C ~ 155°C (lower maximum acceptable if application does not require full range)
• Height - Seated (Max): 0.018" to 0.022" (within 0804 package tolerance)
• Product status: Active or Discontinued (both acceptable for substitution purposes)

All substitute parts listed meet these criteria and are electrically and mechanically interchangeable with the RP104PJ270CS in standard applications.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection (Preferred): RAVF104DJT27R0 (Stackpole Electronics Inc) and YC124-JR-0727RL (YAGEO) are the recommended substitutes. Both parts maintain Active product status, match the RP104PJ270CS temperature coefficient specification (±200ppm/°C), and support the full operating temperature range (-55°C ~ 155°C). RAVF104DJT27R0 carries AEC-Q200 automotive qualification, and YC124-JR-0727RL includes AEC-Q200 qualification with documented applications in DDRAM and SDRAM environments. Both are available in high inventory quantities.

Secondary Selection (Conditional): MNR04M0ABJ270 (Rohm Semiconductor) is electrically equivalent but carries Discontinued status at DiGi Electronics and operates to a maximum temperature of 125°C (versus 155°C for the primary part). This substitute is acceptable only for applications where the operating temperature does not exceed 125°C. The temperature coefficient specification is ±300ppm/°C, which represents a 50% increase in drift compared to the RP104PJ270CS. Use this part only when primary substitutes are unavailable and application thermal requirements permit the reduced temperature range.

All substitute parts comply with RoHS3 regulations, maintain MSL rating 1 (Unlimited), and are mechanically compatible with the 0804 package footprint.

Frequently Asked Questions (FAQ)

Q: Can YC124-JR-0727RL replace RP104PJ270CS in automotive applications? A: Yes. YC124-JR-0727RL carries AEC-Q200 qualification and matches all critical electrical parameters of the RP104PJ270CS, including 27 Ohm resistance, ±5% tolerance, 62.5mW power per element, and ±200ppm/°C temperature coefficient. Both parts support -55°C ~ 155°C operating range.

Q: What is the difference between the temperature coefficients of RP104PJ270CS and MNR04M0ABJ270? A: RP104PJ270CS specifies ±200ppm/°C while MNR04M0ABJ270 specifies ±300ppm/°C. This means the Rohm part exhibits 50% greater resistance drift over temperature. For precision applications requiring tight tolerance maintenance across temperature extremes, the Samsung or Stackpole parts are preferred.

Q: Is MNR04M0ABJ270 still available for new designs? A: MNR04M0ABJ270 is marked as Discontinued at DiGi Electronics. While inventory may exist through alternative distributors, new designs should specify RAVF104DJT27R0 or YC124-JR-0727RL to ensure long-term supply continuity.

Q: Are all substitute parts compatible with the same PCB footprint? A: Yes. All parts use the 0804 package with Convex, Long Side Terminals configuration. Height variations (0.018" to 0.022" seated maximum) fall within standard 0804 package tolerances and do not affect PCB layout or assembly processes.

Q: Which substitute has the highest inventory availability? A: YC124-JR-0727RL (YAGEO) has 262,391 pieces in stock, significantly exceeding inventory levels of other substitutes. RAVF104DJT27R0 (Stackpole) has 10,943 pieces available.

Q: Can I use RAVF104DJT27R0 in non-automotive applications? A: Yes. RAVF104DJT27R0 meets all electrical and mechanical specifications for the RP104PJ270CS and functions in any application within the specified operating parameters. AEC-Q200 qualification indicates automotive-grade reliability but does not restrict use in other applications.

Q: What is the significance of MSL rating 1 (Unlimited)? A: MSL 1 (Unlimited) indicates the component has no moisture sensitivity limitations. These parts do not require special moisture-controlled storage or handling procedures and can be stored under standard warehouse conditions indefinitely without moisture bake-out requirements.
