Substitute Part Grouping Explanation

Substitution for the RP164PJ182CS is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

Resistance value: 1.8k Ohm
Tolerance: ±5%
Number of resistors: 4
Circuit type: Isolated
Temperature coefficient: ±200ppm/°C
Operating temperature range: -55°C ~ 155°C
Package type: 1206 (3216 Metric), Convex, Long Side Terminals

Engineering Selection Recommendations

The RAVF164DJT1K80 from Stackpole Electronics Inc is a qualified substitute for the RP164PJ182CS based on the following engineering criteria:

Electrical Equivalence: All critical electrical parameters match exactly, including resistance value, tolerance, temperature coefficient, and operating temperature range. The substitute component's higher power rating per element (100mW vs. 62.5mW) provides additional thermal margin and does not compromise circuit performance.

Mechanical Compatibility: Package dimensions, pin configuration, and mounting type are identical. The component is suitable for direct PCB footprint replacement without layout modifications.

Compliance Status: Both components are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity ratings. The substitute maintains equivalent environmental and regulatory compliance.

Product Availability: The RAVF164DJT1K80 is classified as active product status, ensuring long-term availability and supply chain continuity compared to the obsolete RP164PJ182CS.

Automotive Qualification: The substitute component carries AEC-Q200 automotive qualification, providing additional reliability assurance for applications requiring automotive-grade components.

Frequently Asked Questions (FAQ)

Q: Can the RAVF164DJT1K80 be used as a direct replacement for the RP164PJ182CS in existing designs?

A: Yes. The RAVF164DJT1K80 meets all mandatory electrical and mechanical parameters. No circuit redesign or PCB layout modification is required. The component is pin-compatible and footprint-compatible.

Q: What is the significance of the higher power rating (100mW vs. 62.5mW) in the substitute part?

A: The higher power rating indicates greater thermal capacity per resistor element. This provides additional design margin and does not negatively impact circuit performance. Applications operating within the original 62.5mW specification will operate with improved thermal headroom.

Q: Are there any temperature or environmental differences between the two parts?

A: No. Both components operate across the identical temperature range (-55°C ~ 155°C) and carry the same temperature coefficient (±200ppm/°C). Environmental compliance ratings are equivalent.

Q: Does the packaging format difference (bulk vs. tape & reel) affect electrical performance?

A: No. Packaging format affects only procurement and assembly logistics. Electrical and mechanical specifications remain identical regardless of packaging format.

Q: Is the RAVF164DJT1K80 suitable for automotive applications?

A: Yes. The substitute component carries AEC-Q200 automotive qualification, making it suitable for automotive-grade applications. The original RP164PJ182CS does not specify automotive qualification.

Q: What is the practical difference in height between the two components (0.61mm vs. 0.60mm)?

A: The 0.01mm difference is within normal manufacturing tolerance and does not affect PCB assembly, clearance, or performance. Both components are mechanically equivalent for practical applications.
