Engineering Selection Recommendations

The 741C083222JP from CTS Resistor Products is a direct functional equivalent to the obsolete RN104PJ222CS. Selection of the CTS substitute is supported by the following engineering factors:

Compliance & Certification Alignment: Both parts maintain ROHS3 compliance and REACH Unaffected status, ensuring regulatory continuity in manufacturing and supply chain operations.

Product Availability: The RN104PJ222CS is obsolete with limited remaining inventory (1130 pcs). The 741C083222JP is actively manufactured by CTS with substantial stock availability (18985 pcs), providing long-term supply security.

Electrical Performance: The CTS part exceeds the minimum power dissipation requirement (63mW vs. 62.5mW) and maintains identical temperature coefficient stability (±200ppm/°C). Both parts deliver equivalent electrical performance within specified tolerance bands.

Thermal Operating Range Consideration: The CTS part operates to -55°C ~ 125°C, which is 30°C narrower at the upper limit compared to the Samsung part (-55°C ~ 155°C). Selection of the CTS substitute is appropriate for applications with maximum operating temperatures at or below 125°C. Applications requiring sustained operation above 125°C require alternative sourcing strategies.

Physical & Mechanical Compatibility: Identical package geometry, pin count, and mounting footprint ensure direct PCB-level compatibility without layout or assembly modifications.

Frequently Asked Questions (FAQ)

Q: Can the 741C083222JP directly replace the RN104PJ222CS on existing PCBs?

A: Yes, for applications operating at or below 125°C. The parts share identical package geometry (0804, Concave, Long Side Terminals), pin count (8), and mounting footprint (2.00mm x 1.00mm). No PCB layout or assembly process changes are required. If your application requires sustained operation above 125°C, the CTS part is not suitable.

Q: What is the key difference between these two parts?

A: The primary difference is operating temperature range. The Samsung RN104PJ222CS operates to 155°C maximum, while the CTS 741C083222JP operates to 125°C maximum. All other electrical and mechanical parameters are equivalent or superior in the CTS part.

Q: Why is the Samsung part listed as obsolete?

A: The RN104PJ222CS is classified as obsolete by Samsung Electro-Mechanics, indicating discontinued manufacturing. The CTS 741C083222JP remains in active production, making it the recommended long-term supply source for this resistor network specification.

Q: Are there any compliance or certification differences?

A: No. Both parts are ROHS3 compliant, REACH Unaffected, and carry identical Moisture Sensitivity Level (MSL 1 - Unlimited). Regulatory and environmental compliance requirements are fully satisfied by either part.

Q: What packaging formats are available for the CTS substitute?

A: The 741C083222JP is supplied in Tape & Reel (TR) format, standard for high-volume surface mount assembly operations. The original Samsung part was supplied in standard packaging. Confirm tape & reel compatibility with your assembly process requirements.

Q: Can I use the CTS part in automotive applications?

A: The 741C083222JP carries AEC-Q200 automotive qualification and is specified for automotive, DDR SDRAM, DRAM, and MDDR applications. If your application requires automotive-grade components, the CTS part meets these requirements.

Q: What is the power dissipation difference, and does it matter?

A: The CTS part is rated at 63mW per element versus 62.5mW for the Samsung part. This 0.5mW difference is negligible and represents a margin increase. The CTS part can safely handle the same thermal loads as the original part.
