Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RP164PJ330CS is determined by the following critical parameters:

Primary Substitution Criteria:

• Resistance value: 33 Ohm (exact match required)
• Number of resistors: 4 elements
• Circuit configuration: Isolated topology
• Package type: 1206 (3216 Metric) with convex, long side terminals
• Pin count: 8 pins
• Mounting: Surface mount

Secondary Compatibility Parameters:

• Tolerance: ±5% or tighter (±1% acceptable as upgrade)
• Temperature coefficient: ±200ppm/°C
• Operating temperature range: Must support -55°C minimum and 155°C maximum
• Power per element: 62.5mW minimum (higher ratings acceptable)
• Regulatory compliance: ROHS3 compliant, REACH unaffected

Substitution Classification:

Direct Equivalents maintain all primary and secondary parameters within specification:

• 742X083330JP (CTS Resistor Products)
• YC164-JR-0733RL (YAGEO)

Upgrade Substitute exceeds performance specifications while maintaining compatibility:

• RAVF164DFT33R0 (Stackpole Electronics Inc) - Enhanced tolerance (±1%) and power rating (100mW)

Engineering Selection Recommendations

For Direct Replacement (Equivalent Performance):

Select either 742X083330JP or YC164-JR-0733RL when the design requires functional equivalence to the RP164PJ330CS. Both parts maintain identical electrical specifications and package dimensions. YC164-JR-0733RL is preferred for applications requiring the full -55°C to 155°C operating range without thermal derating. The 742X083330JP operates to 125°C maximum and is suitable for applications with reduced upper temperature requirements.

For Performance Enhancement (Upgrade Substitute):

The RAVF164DFT33R0 provides improved tolerance (±1% versus ±5%) and increased power dissipation capability (100mW versus 62.5mW per element). This upgrade substitute is applicable when design margins require tighter resistance matching or higher thermal headroom. The RAVF164DFT33R0 maintains full compatibility across the -55°C to 155°C operating range and includes AEC-Q200 automotive qualification.

Regulatory and Compliance Considerations:

All substitute parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory continuity. Moisture sensitivity level remains at MSL 1 (unlimited) across all options, eliminating moisture management constraints during procurement and assembly.

Product Status Impact:

The obsolete status of RP164PJ330CS necessitates transition to active parts. YC164-JR-0733RL offers the highest inventory availability (55,200 pcs in stock) and represents the optimal choice for volume procurement and long-term supply chain stability.

Frequently Asked Questions (FAQ)

Q: Can the 742X083330JP replace the RP164PJ330CS in all applications?

A: The 742X083330JP is electrically equivalent for applications operating within -55°C to 125°C. Applications requiring operation above 125°C must use YC164-JR-0733RL or RAVF164DFT33R0, which support the full -55°C to 155°C range.

Q: What is the difference between direct equivalents and the upgrade substitute?

A: Direct equivalents (742X083330JP and YC164-JR-0733RL) maintain the original ±5% tolerance and 62.5mW power rating. The upgrade substitute RAVF164DFT33R0 provides ±1% tolerance and 100mW power per element, enabling designs with tighter resistance matching and higher thermal margins.

Q: Are all substitute parts pin-compatible with the RP164PJ330CS?

A: Yes. All substitute parts feature 8 pins in isolated 4-resistor configuration with identical pin assignments and terminal positioning for direct PCB footprint compatibility.

Q: Does package height variation affect PCB assembly?

A: The RP164PJ330CS and RAVF164DFT33R0 have seated height of 0.024" (0.60mm), while 742X083330JP and YC164-JR-0733RL have 0.028" (0.70mm). This 0.004" (0.10mm) difference is within standard PCB assembly tolerances and does not require design modification.

Q: Which substitute part offers the best long-term availability?

A: YC164-JR-0733RL from YAGEO provides the highest inventory level (55,200 pcs) and active product status, ensuring sustained availability for ongoing production and future procurement cycles.

Q: Can RAVF164DFT33R0 be used as a direct drop-in replacement without circuit redesign?

A: Yes. The RAVF164DFT33R0 is fully compatible as a direct substitute. The improved tolerance and power rating represent performance enhancements that do not require circuit modification and are backward-compatible with designs specified for the original part.

Q: Are there any thermal management differences between substitute parts?

A: All parts operate across -55°C to 155°C (except 742X083330JP limited to 125°C) with identical ±200ppm/°C temperature coefficient. The RAVF164DFT33R0 provides higher power dissipation capacity (100mW versus 62.5mW), reducing thermal stress in high-current applications.
