Key Parameters

Substitute Part Grouping Explanation

Substitution of the RP164PJ4R3CS is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 4.3 Ohm
• Tolerance: ±5%
• Number of resistors: 4
• Circuit type: Isolated
• Number of pins: 8
• Package / Case: 1206 (3216 Metric), Convex, Long Side Terminals
• Operating temperature range: -55°C ~ 155°C
• Mounting type: Surface Mount

Allowable Variation Parameters:

• Power per element: Substitute must equal or exceed 62.5mW
• Temperature coefficient: Substitute must equal or be superior (lower absolute value)
• Product status: Active substitutes are preferred for obsolete parts

The RAVF164DJT4R30 manufactured by Stackpole Electronics Inc meets all mandatory matching criteria and provides enhanced specifications in power rating (100mW vs. 62.5mW) and temperature coefficient stability (±200ppm/°C vs. ±300ppm/°C).

Frequently Asked Questions (FAQ)

Q: Can the RAVF164DJT4R30 be used as a direct replacement for the RP164PJ4R3CS?

A: Yes. Both components share identical resistance value (4.3 Ohm), tolerance (±5%), circuit type (isolated), pin count (8), and package configuration (1206 Convex, Long Side Terminals). The substitute meets or exceeds all electrical performance parameters of the original part.

Q: What are the key differences between these two parts?

A: The RAVF164DJT4R30 provides higher power dissipation per element (100mW vs. 62.5mW) and superior temperature coefficient stability (±200ppm/°C vs. ±300ppm/°C). The substitute part is active in production, whereas the RP164PJ4R3CS is obsolete.

Q: Are there any PCB layout modifications required when substituting the RAVF164DJT4R30?

A: No. Both components utilize identical 1206 (3216 Metric) package dimensions and pin configurations. Direct footprint compatibility is confirmed.

Q: Does the RAVF164DJT4R30 meet the same compliance standards?

A: Yes. Both parts are ROHS3 compliant and REACH unaffected. The substitute part additionally carries automotive AEC-Q200 qualification.

Q: What is the operating temperature range for the substitute part?
