Substitute Part Grouping Explanation

Substitution eligibility for the RG2012P-66R5-B-T5 is determined by the following critical parameters:

Primary Substitution Criteria:

• Resistance value: 66.5 Ohms (exact match required)
• Tolerance: ±0.1% (exact match required)
• Package: 0805 (2012 Metric) (exact match required)
• Composition: Thin Film (exact match required)
• Temperature Coefficient: ±25ppm/°C (exact match required)
• Operating Temperature Range: -55°C ~ 155°C (exact match required)
• RoHS Compliance: ROHS3 Compliant (exact match required)

Secondary Substitution Criteria:

• Power Rating: 0.125W minimum (equal or higher power rating acceptable)
• Moisture Sensitivity Level: 1 (Unlimited) (equal or lower MSL acceptable)

All substitute parts listed meet or exceed the primary criteria. The TE Connectivity part (2176091-7) provides higher power rating (0.25W) while maintaining all other specifications. All substitute parts are active products with current manufacturing status and full RoHS3 compliance.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts are active products with current manufacturing status and full ROHS3 compliance, ensuring long-term availability and regulatory conformance.

ERA-6AEB66R5V (Panasonic) provides direct equivalence to the RG2012P-66R5-B-T5 with identical power rating (0.125W) and automotive AEC-Q200 qualification. This part is suitable for applications requiring automotive-grade reliability and anti-sulfur performance characteristics.

RT0805BRD0766R5L (YAGEO) offers direct equivalence with identical power rating (0.125W) and all electrical specifications. This part is suitable for general industrial and commercial applications requiring 0.1% tolerance precision.

2176091-7 (TE Connectivity) provides higher power rating capability (0.25W) while maintaining all other electrical and mechanical specifications. This part is suitable for applications where thermal margin or higher power dissipation capacity is beneficial, though the increased height (0.026" vs. 0.020") must be verified for PCB layout compatibility.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 2176091-7 be used as a direct replacement for the RG2012P-66R5-B-T5?

A: The TE Connectivity part is electrically and mechanically compatible with identical resistance, tolerance, package, and operating temperature specifications. The higher power rating (0.25W vs. 0.125W) is a non-limiting advantage. However, the increased seated height (0.026" vs. 0.020") must be verified against PCB layout constraints and clearance requirements.

Q: What is the significance of the ±0.1% tolerance specification?

A: The ±0.1% tolerance indicates precision thin film resistor construction. All substitute parts maintain this tolerance specification, ensuring equivalent accuracy for applications requiring high-precision resistance values.

Q: Are all substitute parts suitable for automotive applications?

A: The ERA-6AEB66R5V (Panasonic) carries automotive AEC-Q200 qualification matching the original RG2012P-66R5-B-T5. The RT0805BRD0766R5L (YAGEO) and 2176091-7 (TE Connectivity) do not carry explicit AEC-Q200 ratings. For automotive applications requiring AEC-Q200 compliance, the Panasonic ERA-6AEB66R5V is the appropriate selection.

Q: What does Moisture Sensitivity Level 1 (Unlimited) mean?

A: MSL 1 (Unlimited) indicates the component has no moisture sensitivity restrictions and requires no special moisture control during storage, handling, or assembly. All substitute parts share this specification.

Q: Are all parts available in Tape & Reel packaging?

A: All listed parts are supplied in Tape & Reel (TR) packaging format, suitable for automated assembly processes.

Q: What is the temperature coefficient significance?

A: The ±25ppm/°C temperature coefficient indicates the resistor's resistance change per degree Celsius across the operating temperature range. All substitute parts maintain identical temperature coefficient specifications, ensuring equivalent thermal stability.

Q: Can these parts be used interchangeably in existing designs?

A: All substitute parts share identical electrical specifications (resistance, tolerance, temperature coefficient, operating temperature range) and package dimensions. Physical height variations must be evaluated for specific PCB layout constraints. Automotive applications must use the AEC-Q200 qualified part (Panasonic ERA-6AEB66R5V) if compliance is required.
