RP104PJ680CS 68 Ohm Isolated 4 Resistor Network Array Equivalent & Substitute Parts

Part Overview

The RP104PJ680CS is a surface-mount resistor network array manufactured by Samsung Electro-Mechanics. This component is a 4-resistor isolated network with 68 Ohm resistance per element, rated at 62.5mW power dissipation per element, and packaged in a 0804 form factor with convex, long-side terminals. The part is currently active in production and maintains full RoHS3 compliance with unlimited moisture sensitivity rating (MSL 1). Substitute parts are necessary when Samsung Electro-Mechanics inventory is unavailable, when alternative packaging formats are required, or when automotive-grade qualification is mandated for specific applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RP104PJ680CS is determined by strict electrical and mechanical parameter matching. All substitute parts must satisfy the following criteria:

Electrical Parameters (Non-Negotiable):

• Resistance value: 68 Ohm
• Tolerance: ±5%
• Circuit configuration: Isolated 4-resistor network
• Power rating per element: 62.5mW minimum
• Temperature coefficient: ±200ppm/°C
• Operating temperature range: -55°C to 155°C minimum

Mechanical Parameters (Non-Negotiable):

• Package type: 0804 form factor
• Terminal configuration: Convex, long-side terminals
• Pin count: 8 pins
• Mounting: Surface mount

Compliance Parameters:

• RoHS3 compliance required
• MSL 1 rating required

All three substitute parts listed (MNR04MRAPJ680, RAVF104DJT68R0, YC124-JR-0768RL) meet these exact specifications and are therefore direct functional equivalents.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection (Active Status): RAVF104DJT68R0 (Stackpole Electronics Inc) and YC124-JR-0768RL (YAGEO) are both active products with full production support. Both parts carry AEC-Q200 automotive qualification, providing additional reliability assurance for applications requiring automotive-grade components. RAVF104DJT68R0 offers the lowest seated height at 0.020" (0.50mm), while YC124-JR-0768RL provides the highest inventory availability at 49,402 pieces.

Secondary Selection (Discontinued Status): MNR04MRAPJ680 (Rohm Semiconductor) is discontinued at DiGi Electronics but maintains 5,028 pieces in current inventory. This part is electrically and mechanically identical to the primary options and remains a valid substitute for applications where existing stock is available.

Compliance Considerations: All substitute parts maintain ROHS3 compliance and MSL 1 rating, matching the regulatory requirements of the RP104PJ680CS. No additional compliance verification is required for direct substitution.

Physical Fit Verification: The RP104PJ680CS has a maximum seated height of 0.018" (0.45mm), which is lower than all substitute parts (0.020" to 0.022"). In space-constrained PCB layouts, this height differential must be evaluated against design clearance specifications. All parts maintain identical footprint dimensions (2.00mm x 1.00mm).

Frequently Asked Questions (FAQ)

Q: Can RAVF104DJT68R0 be used as a direct replacement for RP104PJ680CS in non-automotive applications?

A: Yes. RAVF104DJT68R0 meets all electrical and mechanical specifications of RP104PJ680CS. The AEC-Q200 automotive qualification is an additional feature that does not restrict use in non-automotive circuits. All critical parameters—resistance value, tolerance, power rating, temperature coefficient, operating range, and package configuration—are identical.

Q: What is the significance of the height difference between RP104PJ680CS (0.45mm) and substitute parts (0.50mm to 0.55mm)?

A: The height differential ranges from 0.002" to 0.004" (0.05mm to 0.10mm). This difference is negligible for most applications but must be considered in designs with tight vertical clearance constraints, such as stacked component layouts or confined enclosures. PCB design files should be reviewed to confirm adequate clearance before substitution.

Q: Is MNR04MRAPJ680 suitable for new designs despite being discontinued at DiGi Electronics?

A: MNR04MRAPJ680 is not recommended for new designs. Although 5,028 pieces are currently in inventory, the discontinued status indicates no future production support. RAVF104DJT68R0 or YC124-JR-0768RL are preferred for new designs to ensure long-term supply chain stability.

Q: Are all substitute parts suitable for DDRAM and SDRAM applications?

A: YC124-JR-0768RL is explicitly qualified for DDRAM and SDRAM applications. RAVF104DJT68R0 and MNR04MRAPJ680 do not list specific applications but meet all electrical and mechanical requirements for memory circuit termination networks. Application suitability should be confirmed against circuit design specifications.

Q: What packaging formats are available for these substitute parts?

A: RP104PJ680CS is supplied in standard packaging format. RAVF104DJT68R0 is available in Tape & Reel (TR) format. YC124-JR-0768RL is available in Tape & Reel (TR) format. MNR04MRAPJ680 is available in Cut Tape (CT) and Digi-Reel® formats. Packaging selection depends on production volume and assembly equipment compatibility.

Q: Do all parts comply with REACH regulations?

A: Yes. All parts listed—RP104PJ680CS, MNR04MRAPJ680, RAVF104DJT68R0, and YC124-JR-0768RL—are REACH Unaffected, indicating full compliance with REACH regulatory requirements.
