Parameter Comparison

Engineering Selection Recommendations

The YC122-JR-074K7L from YAGEO is a direct electrical and mechanical equivalent to the RP102PJ472CS. Both components maintain identical specifications across resistance value, tolerance, power rating, temperature coefficient, and operating temperature range. Both parts are ROHS3 compliant and carry Moisture Sensitivity Level 1 classification.

The YC122-JR-074K7L carries AEC-Q200 automotive qualification and is specified for DDRAM and SDRAM applications. The substitute part exhibits a maximum seated height of 0.016" (0.40mm) compared to 0.018" (0.45mm) for the main part, representing a minor dimensional variation within acceptable tolerance for surface-mount assembly processes.

Selection between these parts is based on availability, supply chain requirements, and application-specific qualification needs. Both parts are Active status products suitable for new designs and production applications.

Frequently Asked Questions (FAQ)

Q: Can YC122-JR-074K7L be used as a direct replacement for RP102PJ472CS in existing designs?

A: Yes. The YC122-JR-074K7L meets all electrical specifications including 4.7k Ohm resistance, ±5% tolerance, 62.5mW power per element, ±200ppm/°C temperature coefficient, and -55°C ~ 155°C operating range. The package form factor, pin count, and mounting type are identical. Both components are ROHS3 compliant with MSL 1 rating.

Q: Are there dimensional differences between these parts?

A: Both parts share identical length and width dimensions of 0.039" x 0.039" (1.00mm x 1.00mm). The maximum seated height differs slightly: RP102PJ472CS is 0.018" (0.45mm) while YC122-JR-074K7L is 0.016" (0.40mm). This variation does not affect PCB assembly compatibility.

Q: What is the significance of the 0404 package designation?

A: The 0404 package, also referenced as 1010 Metric, is a surface-mount resistor array package with 4 pins in a convex configuration. This standardized package form ensures mechanical and electrical compatibility between equivalent parts from different manufacturers.

Q: Does the AEC-Q200 qualification of YC122-JR-074K7L affect substitution suitability?

A: AEC-Q200 qualification indicates automotive-grade reliability testing. This certification does not restrict use in non-automotive applications and does not create incompatibility with the non-qualified RP102PJ472CS. Both parts meet the same electrical and mechanical requirements.

Q: What compliance standards apply to both parts?

A: Both RP102PJ472CS and YC122-JR-074K7L are ROHS3 compliant, REACH unaffected, and classified as EAR99 for export control purposes. Both carry Moisture Sensitivity Level 1, indicating unlimited shelf life under standard storage conditions.
