Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RP164PJ684CS is determined by strict alignment with the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 680k Ohm
• Tolerance: ±5%
• Number of resistors: 4
• Circuit type: Isolated
• Number of pins: 8
• Package type: 1206 (3216 Metric), Convex, Long Side Terminals
• Temperature coefficient: ±200ppm/°C
• Operating temperature range: -55°C ~ 155°C
• Mounting type: Surface Mount
• RoHS3 compliance

Allowable Variation Parameters:

• Power per element: Substitute must equal or exceed 62.5mW
• Physical dimensions and height: Must remain within specified tolerances for the 1206 package
• Packaging format: May differ (Tape & Reel acceptable for surface mount assembly)
• Product status: Active status preferred for long-term availability

The RAVF164DJT680K from Stackpole Electronics Inc qualifies as a direct substitute based on full alignment with all mandatory parameters and superior power rating (100mW vs. 62.5mW).

Engineering Selection Recommendations

Primary Substitute: RAVF164DJT680K

The RAVF164DJT680K from Stackpole Electronics Inc is the qualified substitute for the obsolete RP164PJ684CS. Selection rationale:

1. Electrical Equivalence: All critical electrical parameters match exactly, including resistance value, tolerance, temperature coefficient, and operating temperature range.

2. Package Compatibility: Identical 1206 (3216 Metric) package with convex, long side terminals ensures direct PCB footprint compatibility without layout modifications.

3. Power Rating Enhancement: The 100mW power per element rating exceeds the original 62.5mW specification, providing improved thermal margin in applications.

4. Compliance Status: Both components maintain ROHS3 compliance and MSL 1 rating, ensuring environmental and regulatory alignment.

5. Active Product Status: RAVF164DJT680K is actively manufactured and stocked, eliminating obsolescence risk associated with the original part.

6. Automotive Qualification: The substitute carries AEC-Q200 qualification, indicating suitability for automotive and high-reliability applications.

7. Inventory Availability: 843 pieces in stock provide immediate procurement capability.

Frequently Asked Questions (FAQ)

Q: Can RAVF164DJT680K be used as a direct replacement for RP164PJ684CS without PCB modifications?

A: Yes. Both components share identical package geometry (1206 with convex, long side terminals), pin count (8), and physical dimensions (0.126" L x 0.063" W, 0.024" max height). No PCB layout changes are required.

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

A: The higher power rating indicates greater thermal capacity per resistor element. This provides additional safety margin in applications operating near the original power specification and does not create incompatibility.

Q: Are there electrical performance differences between the two parts?

A: No. Both parts specify identical resistance (680k Ohm), tolerance (±5%), temperature coefficient (±200ppm/°C), and operating temperature range (-55°C ~ 155°C). Electrical performance is equivalent.

Q: Why is the substitute part qualified for automotive applications?

A: The RAVF164DJT680K carries AEC-Q200 qualification, a standard for automotive-grade discrete semiconductors and passive components. This qualification indicates compliance with automotive reliability and testing requirements.

Q: Does the packaging format difference (Tape & Reel vs. standard packaging) affect compatibility?

A: No. Tape & Reel is a standard surface mount assembly format. The component itself is identical; only the delivery and handling format differs. This is standard practice in modern electronics manufacturing.

Q: What compliance certifications apply to both parts?

A: Both components are ROHS3 compliant and REACH unaffected. Both maintain Moisture Sensitivity Level 1 (unlimited shelf life under standard conditions).

Q: Is the substitute part suitable for high-temperature applications?

A: Yes. Both parts operate across the identical temperature range of -55°C to 155°C with ±200ppm/°C temperature coefficient, making them suitable for extended temperature applications.
