Substitute Part Grouping Explanation

Substitution eligibility for the RP104PJ473CS is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Requirements:

Resistance value: 47kΩ (exact match)
Tolerance: ±5% (exact match)
Circuit configuration: Isolated 4-resistor network (exact match)
Power per element: 62.5mW (exact match)
Temperature coefficient: ±200ppm/°C (exact match)
Operating temperature range: -55°C to 155°C (exact match)

Mechanical Equivalence Requirements:

Package designation: 0804 with convex, long side terminals (exact match)
Number of pins: 8 (exact match)
Mounting type: Surface Mount (exact match)

Compliance Requirements:

RoHS3 compliance (mandatory)
Moisture sensitivity level: 1 (Unlimited) (exact match)

The substitute part YC124-JR-0747KL meets all electrical and mechanical equivalence criteria. Variations in seated height (0.022" vs. 0.018" maximum) remain within acceptable PCB assembly tolerances for 0804 package specifications and do not affect functional compatibility.

Engineering Selection Recommendations

Primary Selection (RP104PJ473CS - Samsung Electro-Mechanics): The original Samsung part is recommended for applications where established supply chain relationships and Samsung-specific qualification documentation are required. Active product status ensures continued availability and manufacturing consistency.

Substitute Selection (YC124-JR-0747KL - YAGEO): The YAGEO YC124-JR-0747KL provides direct functional equivalence with additional automotive-grade qualification (AEC-Q200) and automotive applications support. This substitute is suitable for designs requiring automotive-qualified components or when YAGEO supply chain advantages apply. Both parts maintain identical electrical performance and RoHS3 compliance.

Compliance Verification: Both components satisfy ROHS3 requirements and maintain unlimited moisture sensitivity ratings (MSL 1), eliminating moisture-related handling constraints during assembly and storage. REACH compliance status is equivalent across both parts.

Frequently Asked Questions (FAQ)

Q: Can YC124-JR-0747KL directly replace RP104PJ473CS in existing designs?

A: Yes. Both components share identical electrical specifications (47kΩ, ±5% tolerance, 62.5mW per element, ±200ppm/°C), circuit configuration (isolated 4-resistor network), and mechanical package (0804 with 8 pins). Pin-to-pin compatibility is confirmed.

Q: What is the significance of the height difference (0.018" vs. 0.022")?

A: The 0.004" (0.10mm) height variation falls within standard PCB assembly tolerances for 0804 surface-mount packages and does not affect solder reflow profiles, component placement, or functional performance.

Q: Are there differences in temperature performance between these parts?

A: No. Both components operate across -55°C to 155°C with identical ±200ppm/°C temperature coefficients, ensuring equivalent thermal stability and performance across the full operating range.

Q: What does "Isolated" circuit type mean for this resistor array?

A: Isolated configuration means each of the four resistor elements operates independently with no internal connections between elements. This allows flexible circuit design where resistors can be configured for different applications without internal coupling effects.

Q: Is automotive qualification relevant for non-automotive applications?

A: The AEC-Q200 qualification on the YAGEO part indicates enhanced reliability testing and quality standards. This qualification does not restrict use in non-automotive applications; it confirms the part meets stringent reliability requirements applicable across multiple industries.

Q: What packaging options are available for these parts?

A: RP104PJ473CS is available in standard packaging. YC124-JR-0747KL is available in Cut Tape (CT) and Digi-Reel® packaging options, providing flexibility for different procurement and assembly workflows.

Q: Are there any moisture handling requirements?

A: No. Both parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity constraints. Standard storage conditions without desiccant requirements apply.
