RC1210FR-07191RL Equivalent & Substitute Parts

Part Overview

The RC1210FR-07191RL is a 191 Ohm ±1% 0.5W chip resistor manufactured by YAGEO in the 1210 (3225 Metric) package. This thick film, moisture-resistant component is currently in active production status with 1008 pieces available in stock. Substitute parts are necessary when YAGEO supply is constrained, when design requirements mandate specific manufacturer certifications such as automotive qualification, or when alternative sourcing reduces procurement lead times and cost.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the RC1210FR-07191RL is determined by strict equivalence across the following parameters:

• Resistance value: 191 Ohms
• Tolerance: ±1%
• Power rating: 0.5W
• Package designation: 1210 (3225 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C to 155°C
• Moisture sensitivity level: 1 (Unlimited)
• RoHS compliance: ROHS3 Compliant

The ERJ-14NF1910U from Panasonic Electronic Components meets all electrical and mechanical parameters required for direct substitution. Physical dimensions vary slightly within acceptable tolerances for the 1210 package class. The primary distinction is the inclusion of AEC-Q200 automotive qualification in the Panasonic part, which provides additional reliability assurance for automotive applications.

Parameter Comparison

Engineering Selection Recommendations

The RC1210FR-07191RL remains the primary selection for new designs due to its active product status. The ERJ-14NF1910U serves as a qualified substitute when YAGEO supply is unavailable. The Panasonic part carries AEC-Q200 automotive qualification, making it suitable for automotive applications where this certification is required. However, the ERJ-14NF1910U is designated "Not For New Designs," indicating Panasonic's intent to phase out this part number. Selection should prioritize the active YAGEO part for long-term design stability unless automotive qualification is a mandatory requirement.

Frequently Asked Questions (FAQ)

Q: Can ERJ-14NF1910U be used as a direct replacement for RC1210FR-07191RL?

A: Yes. Both parts share identical electrical specifications (191 Ohms ±1%, 0.5W), composition (thick film), temperature characteristics (±100ppm/°C, -55°C to 155°C), and package designation (1210/3225 Metric). Physical dimensions vary slightly but remain within acceptable tolerances for the 1210 package class.

Q: What is the significance of the AEC-Q200 rating on the Panasonic part?

A: AEC-Q200 is an automotive qualification standard. The ERJ-14NF1910U meets this specification, making it suitable for automotive applications where this certification is contractually or functionally required. The RC1210FR-07191RL does not carry this designation.

Q: Why is the Panasonic part marked "Not For New Designs"?

A: This designation indicates the manufacturer is discontinuing the part number. While it remains available for existing designs, Panasonic does not recommend its use in new product development. The RC1210FR-07191RL should be the primary choice for new designs.

Q: Are there dimensional differences between these parts?

A: Minor dimensional variations exist. RC1210FR-07191RL: 0.122" L × 0.102" W × 0.024" H max. ERJ-14NF1910U: 0.126" L × 0.098" W × 0.028" H max. These differences fall within standard 1210 package tolerances and do not affect PCB layout or functionality.

Q: Do both parts meet RoHS compliance requirements?

A: Yes. Both the RC1210FR-07191RL and ERJ-14NF1910U are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards.
