Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RP104PJ333CS is determined by strict equivalence across the following critical parameters:

Electrical Parameters (Non-Negotiable):

• Resistance value: 33kΩ
• Tolerance: ±5%
• Circuit type: Isolated (4 independent resistor elements)
• Power per element: 62.5mW minimum
• Temperature coefficient: ±200ppm/°C
• Operating temperature range: -55°C to 155°C minimum

Mechanical Parameters (Non-Negotiable):

• Package type: 0804 with convex, long side terminals
• Number of pins: 8
• Mounting type: Surface mount
• Physical dimensions: 0.079" L × 0.039" W (2.00mm × 1.00mm)

Compliance Parameters:

• RoHS3 compliance required
• MSL 1 (Unlimited) moisture sensitivity level
• REACH unaffected status

All substitute parts listed meet these criteria without exception. Substitution is valid only when all parameters align with the specifications above.

Engineering Selection Recommendations

Primary Selection: RP104PJ333CS (Samsung Electro-Mechanics)

The RP104PJ333CS is the specified part with active production status and adequate inventory (1188 units). This part should be the first choice for new designs and production orders.

First Substitute: YC124-JR-0733KL (YAGEO)

The YC124-JR-0733KL is recommended as the primary substitute option. This part maintains active production status with the highest inventory availability (10300 units), ensuring supply continuity. All electrical and mechanical parameters are identical to the primary part. The component is qualified for automotive applications under AEC-Q200 standard and is suitable for DDRAM and SDRAM applications. The maximum seated height of 0.022" (0.55mm) is within acceptable tolerance for standard PCB assembly processes.

Secondary Substitute: MNR04MRAPJ333 (Rohm Semiconductor)

The MNR04MRAPJ333 is functionally equivalent but carries discontinued status at DiGi Electronics, indicating reduced long-term availability. This part should be considered only when the primary and first substitute options are unavailable. Inventory is limited to 749 units. The maximum seated height of 0.020" (0.50mm) is compatible with standard assembly processes.

Selection Criteria Summary:

All three parts are electrically and mechanically interchangeable. Selection should prioritize:

1. Product status (active vs. discontinued)
2. Inventory availability and lead time
3. Packaging format compatibility with assembly processes
4. Long-term supply chain stability

Frequently Asked Questions (FAQ)

Q: Can the YC124-JR-0733KL be used as a direct replacement for the RP104PJ333CS?

A: Yes. The YC124-JR-0733KL is a direct functional equivalent. All electrical parameters (resistance, tolerance, temperature coefficient, power rating, operating temperature range) are identical. The package type, pin configuration, and physical footprint are identical. No circuit modifications or PCB layout changes are required.

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

A: The seated heights are: RP104PJ333CS (0.45mm), MNR04MRAPJ333 (0.50mm), and YC124-JR-0733KL (0.55mm). These differences are within standard PCB assembly tolerances and do not affect functionality or compatibility. Height variation is not a limiting factor for substitution in standard surface-mount applications.

Q: Why is the MNR04MRAPJ333 marked as discontinued?

A: The MNR04MRAPJ333 is discontinued at DiGi Electronics, indicating reduced availability through this distribution channel. However, the part may remain available through other suppliers. Discontinued status does not affect electrical or mechanical compatibility; it reflects supply chain availability only.

Q: Are all three parts RoHS3 compliant?

A: Yes. All three parts (RP104PJ333CS, MNR04MRAPJ333, and YC124-JR-0733KL) are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: What is the significance of the isolated circuit type?

A: The isolated circuit type means each of the four resistor elements operates independently with no electrical connection between them. This configuration is essential for applications requiring separate resistor functions within a single package. All substitute parts maintain this isolated topology.

Q: Can I mix different manufacturers' parts in the same production batch?

A: Yes. All three parts are functionally equivalent and can be used interchangeably within the same circuit design. However, for traceability and quality control purposes, many manufacturers prefer to maintain consistent sourcing within a single production run.

Q: What packaging formats are available?

A: The RP104PJ333CS is supplied in standard packaging (format not specified). The MNR04MRAPJ333 is available in Cut Tape (CT) and Digi-Reel® formats. The YC124-JR-0733KL is supplied in Tape & Reel (TR) format. Packaging selection should align with your assembly process requirements.

Q: Is the YC124-JR-0733KL suitable for automotive applications?

A: Yes. The YC124-JR-0733KL is qualified for automotive applications under the AEC-Q200 standard and is specified for DDRAM and SDRAM applications. This qualification extends its applicability beyond general-purpose circuits.

Q: What is the MSL 1 (Unlimited) moisture sensitivity rating?

A: MSL 1 (Unlimited) indicates the component has no moisture sensitivity limitations. The part can be stored indefinitely without special moisture control measures and does not require baking before reflow soldering. This is the least restrictive moisture sensitivity classification.
