Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RNCF0805BKE412R is determined by the following critical parameters:

Primary Matching Criteria:

• Resistance value: 412 Ohms
• Tolerance: ±0.1%
• Package: 0805 (2012 Metric)
• Composition: Thin Film
• Temperature Coefficient: ±25ppm/°C
• Operating Temperature Range: -55°C ~ 155°C
• RoHS Compliance: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Secondary Consideration:

• Power Rating: Substitute parts must meet or exceed the 0.25W requirement for direct replacement in identical circuit applications

The substitute parts listed below satisfy the primary matching criteria. The ERA-6AEB4120V features a reduced power rating of 0.125W (1/8W), which represents a functional limitation in applications requiring full 0.25W dissipation capacity. The 8-2176091-1 maintains full electrical and mechanical equivalence with identical power rating and all specified parameters.

Parameter Comparison

Engineering Selection Recommendations

Full Equivalence (8-2176091-1): The TE Connectivity 8-2176091-1 provides complete electrical and mechanical equivalence to the RNCF0805BKE412R. Both components share identical resistance, tolerance, power rating, package dimensions, temperature coefficient, and operating temperature range. Both maintain ROHS3 compliance and MSL 1 rating. This part is suitable for direct substitution in all applications where the original part is specified.

Conditional Substitution (ERA-6AEB4120V): The Panasonic ERA-6AEB4120V matches all electrical parameters and package specifications but features a reduced power rating of 0.125W versus the original 0.25W. This part maintains AEC-Q200 automotive qualification and ROHS3 compliance. Substitution is appropriate only in applications where the circuit power dissipation does not exceed 0.125W at the 412 Ohm resistance value. Applications requiring the full 0.25W capacity must use either the original RNCF0805BKE412R or the equivalent 8-2176091-1.

Frequently Asked Questions (FAQ)

Q: Can the ERA-6AEB4120V be used as a direct replacement for the RNCF0805BKE412R?

A: The ERA-6AEB4120V is electrically compatible in terms of resistance, tolerance, and temperature characteristics. However, the reduced power rating (0.125W versus 0.25W) limits its application scope. Direct replacement is only valid if circuit analysis confirms power dissipation remains below 0.125W. For applications requiring full 0.25W capacity, use the 8-2176091-1 or original RNCF0805BKE412R.

Q: Are all substitute parts automotive-qualified?

A: The RNCF0805BKE412R and ERA-6AEB4120V both carry AEC-Q200 automotive qualification. The TE Connectivity 8-2176091-1 does not list AEC-Q200 certification in the provided specifications. For automotive applications requiring AEC-Q200 compliance, the Stackpole or Panasonic parts are the appropriate selections.

Q: What is the physical difference between these parts?

A: All three parts use the 0805 (2012 Metric) package with identical length and width (0.079" L x 0.049" W / 2.00mm x 1.25mm). Maximum seated heights are 0.026" (0.65mm) for both the RNCF0805BKE412R and 8-2176091-1, and 0.024" (0.60mm) for the ERA-6AEB4120V. These dimensional variations are negligible for standard PCB assembly.

Q: Does packaging format affect substitution eligibility?

A: Packaging format (Tape & Reel versus Cut Tape) does not affect electrical or mechanical compatibility. The RNCF0805BKE412R and 8-2176091-1 are supplied in Tape & Reel format, while the ERA-6AEB4120V is available in Cut Tape and Digi-Reel formats. Selection should be based on procurement and assembly process requirements rather than component performance.

Q: Are all parts RoHS compliant?

A: All three parts are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating, indicating no special storage or handling requirements beyond standard component practices.
