Engineering Selection Recommendations

For Direct Replacement (Pin-Compatible, Specification-Matched):

Select YC164-JR-0782RL when procurement of the original RP164PJ820CS is no longer feasible. This YAGEO part maintains identical electrical specifications (82 Ohm ±5%, 62.5mW per element, ±200ppm/°C) and mechanical configuration (1206 package, 8-pin isolated array). Both parts are ROHS3 compliant with MSL 1 rating. The YC164-JR-0782RL is currently in active production with confirmed inventory availability.

For Performance Upgrade (Enhanced Specifications):

Select RAVF164DFT82R0 when design margins or reliability improvements are acceptable. This Stackpole part provides tighter tolerance (±1% vs ±5%) and higher power dissipation capability (100mW vs 62.5mW per element) while maintaining identical package footprint and pin configuration. The upgrade is suitable for applications requiring improved accuracy or thermal headroom. RAVF164DFT82R0 is ROHS3 compliant, MSL 1 rated, and actively manufactured.

Compliance Verification:

All three parts (original, direct substitute, and upgrade) meet ROHS3 compliance and carry MSL 1 (unlimited moisture sensitivity) classification. No additional environmental or regulatory constraints apply to substitution decisions based on provided certifications.

Frequently Asked Questions (FAQ)

Q: Can YC164-JR-0782RL be used as a direct replacement for RP164PJ820CS without PCB modification?

A: Yes. The YC164-JR-0782RL maintains identical package designation (1206 with convex, long side terminals), 8-pin configuration, and footprint dimensions (0.126" L x 0.063" W). No PCB layout changes are required. The maximum seated height difference (0.028" vs 0.024") does not affect assembly compatibility.

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

A: YC164-JR-0782RL provides specification parity with the original part (±5% tolerance, 62.5mW per element). RAVF164DFT82R0 offers improved tolerance (±1%) and higher power rating (100mW per element) while maintaining identical package and pin configuration. Selection depends on whether enhanced accuracy or thermal performance is required for the application.

Q: Are there any height clearance concerns when substituting with YC164-JR-0782RL?

A: The YC164-JR-0782RL seated height is 0.028" (0.70mm) compared to 0.024" (0.60mm) for the original RP164PJ820CS. This 0.004" (0.10mm) difference is within typical PCB assembly tolerances and does not create clearance issues in standard surface mount applications. Verify clearance only if the design has height-critical constraints below 0.030".

Q: Do all three parts support automotive applications?

A: The original RP164PJ820CS does not list automotive applications. YC164-JR-0782RL and RAVF164DFT82R0 both specify Automotive AEC-Q200 compliance. If automotive qualification is required, use YC164-JR-0782RL or RAVF164DFT82R0.

Q: What is the significance of the isolated circuit type for substitution?

A: Isolated configuration means each of the four resistor elements operates independently with no electrical connection between them. This is a critical parameter—substitutes must maintain isolated topology. All identified substitutes preserve this configuration.

Q: Can RAVF164DFT82R0 be used in applications originally designed for RP164PJ820CS?

A: Yes. RAVF164DFT82R0 meets or exceeds all electrical and mechanical requirements of the original part. The ±1% tolerance is tighter than the ±5% specification, and 100mW per element exceeds the 62.5mW requirement. The part is backward-compatible with identical package and pin assignment.

Q: What packaging formats are available for these substitutes?

A: YC164-JR-0782RL is supplied in Tape & Reel (TR) format. RAVF164DFT82R0 is supplied in Tape & Reel (TR) format. The original RP164PJ820CS packaging format is not specified in available data. Confirm packaging requirements with procurement specifications.

Q: Are there any temperature or environmental limitations that would prevent substitution?

A: No. All three parts operate across -55°C to 155°C with ±200ppm/°C temperature coefficient. All are ROHS3 compliant and carry MSL 1 (unlimited) moisture sensitivity rating. No additional environmental constraints apply.
