RP104PJ7R5CS Equivalent & Substitute Parts

Part Overview

The RP104PJ7R5CS is a 4-resistor isolated network array manufactured by Samsung Electro-Mechanics. This surface-mount component features 7.5 Ohm resistors with ±5% tolerance and 62.5mW power per element in a 0804 package format. The part is currently in active production status with 867 pieces available in inventory. Substitute parts are identified when original stock becomes unavailable, when supply chain constraints occur, or when design requirements permit alternative qualified sources meeting equivalent electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RP104PJ7R5CS is determined by strict equivalence across the following critical parameters:

Electrical Parameters (Must Match):

• Resistance value: 7.5 Ohms
• Tolerance: ±5%
• Number of resistor elements: 4
• Power per element: 62.5mW
• Circuit configuration: Isolated
• Operating temperature range: -55°C ~ 155°C

Mechanical Parameters (Must Match):

• Package format: 0804, Convex, Long Side Terminals
• Number of pins: 8
• Mounting type: Surface Mount
• Physical dimensions: 0.079" L x 0.039" W (2.00mm x 1.00mm)

Compliance Parameters (Must Match):

• RoHS3 Compliance
• Moisture Sensitivity Level 1

The RAVF104DJT7R50 from Stackpole Electronics Inc meets all mandatory electrical and mechanical equivalence criteria. The temperature coefficient differs (±300ppm/°C versus ±200ppm/°C), which represents a relaxation of the original specification and does not prevent substitution. The maximum seated height increases from 0.018" to 0.020", remaining within typical PCB assembly tolerances for 0804 packages.

Parameter Comparison

Engineering Selection Recommendations

The RAVF104DJT7R50 is qualified as a direct substitute for the RP104PJ7R5CS based on electrical and mechanical equivalence. Both parts maintain active production status and ROHS3 compliance. The Stackpole part carries AEC-Q200 automotive qualification, which represents an additional quality assurance level beyond the base specification.

Selection between these parts should be based on:

1. Availability: The RAVF104DJT7R50 maintains higher inventory levels (20,903 pieces) compared to the RP104PJ7R5CS (867 pieces).

2. Supply Chain Requirements: The Stackpole part is supplied in Tape & Reel packaging, which is standard for high-volume automated assembly operations.

3. Temperature Coefficient Tolerance: Applications requiring temperature stability better than ±300ppm/°C must retain the Samsung part. Applications with ±300ppm/°C tolerance or less stringent requirements accept the Stackpole substitute.

4. Automotive Applications: The AEC-Q200 qualification of the RAVF104DJT7R50 is required for automotive-grade designs.

Both parts are suitable for general industrial and commercial applications within the specified operating temperature range.

Frequently Asked Questions (FAQ)

Q: Can the RAVF104DJT7R50 be used as a direct replacement on existing PCBs designed for the RP104PJ7R5CS?

A: Yes. Both parts use identical 0804 package geometry with 8-pin configurations and convex long-side terminals. The maximum seated height difference (0.002" / 0.05mm) is within standard PCB assembly tolerances and does not affect placement or reflow processes.

Q: What is the significance of the temperature coefficient difference between these parts?

A: The RP104PJ7R5CS specifies ±200ppm/°C while the RAVF104DJT7R50 specifies ±300ppm/°C. This means the Stackpole part exhibits greater resistance drift across temperature extremes. For applications operating across the full -55°C to 155°C range, the maximum resistance variation increases from ±1.5% to ±2.25% when combined with the ±5% tolerance. Applications requiring tighter temperature stability must use the Samsung part.

Q: Are there packaging differences between these substitutes?

A: The RP104PJ7R5CS is supplied in standard packaging format. The RAVF104DJT7R50 is supplied in Tape & Reel (TR) format, which is standard for automated pick-and-place assembly. Both formats are compatible with standard SMT assembly equipment.

Q: What compliance certifications apply to both parts?

A: Both parts are ROHS3 compliant and REACH unaffected. The RAVF104DJT7R50 carries additional AEC-Q200 automotive qualification. Both parts have Moisture Sensitivity Level 1 (unlimited shelf life under standard storage conditions).

Q: Can the RAVF104DJT7R50 be used in automotive applications where the RP104PJ7R5CS was originally specified?

A: Yes. The AEC-Q200 qualification of the Stackpole part exceeds the base specification and is suitable for automotive-grade designs. The electrical and mechanical parameters remain equivalent.

Q: What is the inventory status for these parts?

A: The RP104PJ7R5CS has 867 pieces in stock. The RAVF104DJT7R50 has 20,903 pieces in stock, providing significantly greater availability for high-volume requirements.
