Mandatory Matching Parameters:

• Resistance value: 1.1k Ohm
• Number of resistors: 4
• Circuit type: Isolated
• Number of pins: 8
• Package / Case: 1206 (3216 Metric), Convex, Long Side Terminals
• Mounting type: Surface Mount
• Operating temperature range: -55°C ~ 155°C minimum
• Temperature coefficient: ±200ppm/°C
• RoHS3 compliance

Allowable Variation Parameters:

• Tolerance: May be equal or tighter (±5% or better)
• Power per element: May be equal or higher (62.5mW or greater)
• Product status: Active status preferred for obsolete parts

Both identified substitute parts meet all mandatory parameters and represent valid alternatives for the obsolete RP164PJ112CS.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent: YC164-JR-071K1L (YAGEO)

The YC164-JR-071K1L provides direct functional equivalence to the RP164PJ112CS. Both parts share identical electrical specifications: 1.1k Ohm resistance, ±5% tolerance, 62.5mW power per element, and ±200ppm/°C temperature coefficient. The YAGEO part maintains the same 1206 package footprint and pin configuration. As an active product with ROHS3 compliance and REACH unaffected status, this substitute ensures procurement continuity for the obsolete Samsung component. The YC164-JR-071K1L is qualified for automotive AEC-Q200 applications, expanding potential use cases.

Enhanced Upgrade: RAVF164DFT1K10 (Stackpole Electronics Inc)

The RAVF164DFT1K10 functions as an enhanced substitute with improved electrical performance. This part maintains all mandatory parameters while offering tighter tolerance (±1% versus ±5%) and higher power dissipation capability (100mW per element versus 62.5mW). The enhanced specifications provide additional design margin for applications requiring higher power handling or tighter resistance matching. The Stackpole component is also automotive AEC-Q200 qualified and ROHS3 compliant. Height-seated specification matches the original RP164PJ112CS at 0.024" (0.60mm), ensuring identical PCB assembly compatibility.

Both substitutes are active products with established supply chains, eliminating obsolescence risk associated with the original Samsung part.

Frequently Asked Questions (FAQ)

Q: Can YC164-JR-071K1L directly replace RP164PJ112CS without circuit modification?

A: Yes. The YC164-JR-071K1L is a direct equivalent with identical electrical and mechanical specifications. No circuit modifications are required. Both parts feature 1.1k Ohm ±5% resistance, 62.5mW power per element, and identical 1206 package dimensions with 8-pin isolated configuration.

Q: What is the advantage of using RAVF164DFT1K10 over YC164-JR-071K1L?

A: The RAVF164DFT1K10 offers two performance enhancements: tighter tolerance (±1% versus ±5%) and higher power dissipation (100mW versus 62.5mW per element). These improvements provide additional design margin for applications requiring higher precision or greater thermal headroom. Circuit functionality remains identical; the upgrade is optional based on application requirements.

Q: Are all three parts compatible with the same PCB footprint?

A: Yes. All three parts use the 1206 (3216 Metric) package with identical length and width dimensions (0.126" L x 0.063" W / 3.20mm x 1.60mm). Height-seated specifications are 0.024" (0.60mm) for RP164PJ112CS and RAVF164DFT1K10, and 0.028" (0.70mm) for YC164-JR-071K1L. These minimal height variations do not affect PCB assembly compatibility.

Q: Do the substitute parts meet automotive qualification requirements?

A: Both YC164-JR-071K1L and RAVF164DFT1K10 are qualified to automotive AEC-Q200 standard. The original RP164PJ112CS does not list automotive qualification. If automotive qualification is required, either substitute part is suitable.

Q: What is the moisture sensitivity level for these parts?

A: All three parts carry Moisture Sensitivity Level (MSL) 1, indicating unlimited shelf life without moisture control requirements. Standard handling and storage practices are sufficient.

Q: Are these parts RoHS compliant?

A: Yes. All three parts are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic component manufacturing and distribution.

Q: What is the temperature coefficient specification, and why is it important?

A: All three parts specify ±200ppm/°C temperature coefficient across the -55°C to 155°C operating range. This parameter defines resistance value drift relative to temperature changes. Identical specifications ensure equivalent thermal performance in temperature-sensitive applications.
