RP164PJ123CS Equivalent & Substitute Parts Reference

Part Overview

The RP164PJ123CS is a 4-resistor network array manufactured by Samsung Electro-Mechanics, featuring 12kΩ ±5% isolated resistors in a 1206 (3216 Metric) surface mount package. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement continuity. The part delivers 62.5mW power per element with ±200ppm/°C temperature coefficient across an operating range of -55°C to 155°C. Substitutes must maintain electrical performance within the specified tolerance and thermal parameters while accommodating available packaging and inventory options.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RP164PJ123CS is determined by strict alignment with the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 12kΩ
• Number of resistors: 4
• Circuit type: Isolated
• Package / Case: 1206 (3216 Metric), Convex, Long Side Terminals
• Number of pins: 8
• Mounting type: Surface Mount
• Operating temperature range: -55°C to 155°C minimum
• Temperature coefficient: ±200ppm/°C

Allowable Variation Parameters:

• Tolerance: ±5% or tighter (±1% is acceptable as an upgrade)
• Power per element: 62.5mW or higher (100mW is acceptable as an upgrade)
• Packaging format: Tape & Reel acceptable for surface mount assembly
• Product status: Active preferred over obsolete for long-term availability

The two identified substitutes meet all mandatory parameters. YC164-JR-0712KL provides direct electrical equivalence with active product status. RAVF164DFT12K0 offers enhanced specifications (±1% tolerance, 100mW power rating) with automotive qualification.

Engineering Selection Recommendations

YC164-JR-0712KL (Direct Equivalent)

This YAGEO part provides electrical and mechanical equivalence to the RP164PJ123CS with active product status. Specifications are identical across all critical parameters: 12kΩ ±5% resistance, 62.5mW power per element, ±200ppm/°C temperature coefficient, and -55°C to 155°C operating range. The 1206 package dimensions and 8-pin isolated configuration ensure PCB footprint compatibility. ROHS3 compliance and MSL 1 rating match the original part. Current inventory of 20,782 units supports production continuity. This substitute is suitable for direct replacement in existing designs without circuit modification.

RAVF164DFT12K0 (Upgrade Substitute)

This Stackpole Electronics part meets all mandatory electrical and mechanical requirements while providing enhanced specifications. The ±1% tolerance offers improved resistance accuracy compared to the ±5% specification of the main part. The 100mW power per element rating exceeds the 62.5mW requirement, providing additional thermal margin. AEC-Q200 automotive qualification and active product status ensure long-term availability. The 0.024" (0.60mm) seated height matches the original part exactly. ROHS3 compliance and MSL 1 rating are maintained. This substitute is suitable for applications requiring tighter tolerance control or higher power dissipation capability.

Frequently Asked Questions (FAQ)

Q: Can YC164-JR-0712KL be used as a direct replacement for RP164PJ123CS without design changes?

A: Yes. The YC164-JR-0712KL maintains identical electrical specifications (12kΩ ±5%, 62.5mW, ±200ppm/°C) and mechanical compatibility (1206 package, 8-pin isolated configuration). No circuit modifications are required. The 0.004" (0.10mm) difference in seated height is within typical PCB assembly tolerances.

Q: What is the advantage of RAVF164DFT12K0 over the direct equivalent?

A: RAVF164DFT12K0 provides two specification improvements: ±1% tolerance versus ±5%, and 100mW power per element versus 62.5mW. These enhancements support applications requiring tighter resistance accuracy or higher thermal performance. The part maintains identical package dimensions and pin configuration.

Q: Are all three parts ROHS3 compliant?

A: Yes. RP164PJ123CS, YC164-JR-0712KL, and RAVF164DFT12K0 are all ROHS3 compliant with REACH Unaffected status, meeting current environmental regulations.

Q: Does the packaging format affect substitution compatibility?

A: Packaging format (Tape & Reel for substitutes versus unspecified for the main part) does not affect electrical or mechanical compatibility. Both formats are standard for surface mount assembly. Tape & Reel packaging is suitable for automated pick-and-place processes.

Q: What is the significance of the isolated circuit type?

A: Isolated circuit type indicates that each of the four resistors operates independently with separate pin connections. This configuration requires 8 pins total (2 per resistor). Substitutes must maintain this isolated topology to ensure pin-for-pin compatibility and proper circuit function.

Q: Can RAVF164DFT12K0 be used in applications originally designed for RP164PJ123CS?

A: Yes. RAVF164DFT12K0 meets or exceeds all electrical and thermal requirements of the original part. The tighter tolerance and higher power rating provide enhanced performance margins. No design changes are necessary.

Q: What is the moisture sensitivity level, and why does it matter?

A: MSL 1 (Unlimited) indicates that all three parts have no moisture sensitivity restrictions. These components can be stored and handled without special humidity controls or floor-life limitations, simplifying inventory management and assembly processes.

Q: Are there any temperature-related limitations when substituting these parts?

A: No. All three parts operate across the identical temperature range of -55°C to 155°C with ±200ppm/°C temperature coefficient. Thermal performance is equivalent across the specified operating envelope.
