RP104PJ750CS Equivalent & Substitute Parts

Part Overview

The RP104PJ750CS is a 75 Ohm isolated 4-resistor network array manufactured by Samsung Electro-Mechanics. This surface-mount component features ±5% tolerance, 62.5mW power per element, and operates across -55°C to 155°C. The part is Active status and RoHS3 compliant, designed for applications requiring precision resistor networks in compact 0804 package form factors. Substitute parts are identified when equivalent electrical specifications and mechanical compatibility are maintained across the same package and performance parameters.

Substitute Part Grouping Explanation

Substitution of the RP104PJ750CS is determined by strict equivalence across the following critical parameters:

Resistance Value: 75 Ohm (exact match required)
Tolerance: ±5% (exact match required)
Circuit Configuration: Isolated 4-resistor network (exact match required)
Power Per Element: 62.5mW (exact match required)
Temperature Coefficient: ±200ppm/°C (exact match required)
Operating Temperature Range: -55°C ~ 155°C (exact match required)
Package Form Factor: 0804, Convex, Long Side Terminals (exact match required)
Pin Count: 8 pins (exact match required)
Mounting Technology: Surface Mount (exact match required)

The substitute part YC124-JR-0775RL meets all these criteria. Both parts maintain identical electrical performance specifications and mechanical compatibility within the 0804 package envelope. Compliance certifications (RoHS3, REACH Unaffected) are equivalent across both manufacturers.

Engineering Selection Recommendations

Both RP104PJ750CS and YC124-JR-0775RL are Active status components with full RoHS3 compliance and REACH Unaffected designation. Selection between these parts is based on availability, supply chain requirements, and packaging format preference.

The RP104PJ750CS is supplied in standard packaging format. The YC124-JR-0775RL is supplied in Tape & Reel (TR) format and carries AEC-Q200 automotive qualification, making it suitable for automotive-grade applications requiring documented quality assurance. The YC124-JR-0775RL also includes documented applications for DDRAM and SDRAM systems.

Height difference of 0.004" (0.10mm) between seated maximums (0.018" vs 0.022") is within typical PCB assembly tolerances and does not affect functional compatibility in standard surface-mount applications.

Frequently Asked Questions (FAQ)

Q: Can YC124-JR-0775RL directly replace RP104PJ750CS in existing designs?

A: Yes. Both parts maintain identical electrical specifications (75 Ohm, ±5%, 62.5mW per element, ±200ppm/°C) and mechanical compatibility within the 0804 package. Pin count, terminal configuration, and mounting technology are equivalent.

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

A: The RP104PJ750CS has a maximum seated height of 0.018" (0.45mm), while YC124-JR-0775RL is 0.022" (0.55mm). This 0.004" (0.10mm) difference is within standard PCB assembly clearance specifications and does not impact board-level compatibility for typical applications.

Q: Does the AEC-Q200 qualification on YC124-JR-0775RL affect its use in non-automotive applications?

A: No. AEC-Q200 qualification indicates additional quality and reliability testing. Parts meeting automotive standards are fully compatible with industrial and commercial applications. The qualification does not restrict use in non-automotive designs.

Q: Are the packaging formats interchangeable?

A: RP104PJ750CS uses standard packaging, while YC124-JR-0775RL is supplied in Tape & Reel (TR) format. Both formats contain identical components. Selection depends on assembly process requirements and inventory management preferences.

Q: What parameters must remain identical for substitution?

A: Resistance value (75 Ohm), tolerance (±5%), circuit type (Isolated), power per element (62.5mW), temperature coefficient (±200ppm/°C), operating range (-55°C ~ 155°C), package form (0804), pin count (8), and mounting type (Surface Mount) must all match exactly.
