RT1206DRD0791RL Equivalent & Substitute Parts

Part Overview

The RT1206DRD0791RL is a 91 Ohm ±0.5% thin film chip resistor in 1206 (3216 Metric) package rated for 0.25W (1/4W) power dissipation. Manufactured by YAGEO, this component is actively produced and widely used in general-purpose electronic applications. Substitute parts are identified based on matching electrical specifications (resistance value, power rating, package size) and mechanical compatibility, with tolerance and temperature coefficient as primary selection criteria.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RT1206DRD0791RL are qualified based on the following criteria:

Mandatory Matching Parameters:

• Resistance value: 91 Ohms
• Power rating: 0.25W (1/4W) minimum
• Package: 1206 (3216 Metric)
• Composition: Thin Film
• Temperature coefficient: ±25ppm/°C
• Operating temperature range: -55°C ~ 155°C minimum
• RoHS3 compliance

Allowable Variations:

• Tolerance: May be equal to or tighter than ±0.5%
• Physical dimensions: Minor variations within package specification are acceptable
• Additional certifications (AEC-Q200, anti-sulfur features) do not disqualify substitution

Two substitute parts meet these criteria: ERA-8AEB910V (Panasonic) and RG3216P-91R0-B-T1 (Susumu). Both offer improved tolerance (±0.1%) and automotive-grade qualification, making them suitable direct replacements.

Parameter Comparison

Engineering Selection Recommendations

RT1206DRD0791RL (YAGEO): Primary choice for general-purpose applications where standard tolerance and non-automotive qualification are acceptable. Active product status with 656 units in stock.

ERA-8AEB910V (Panasonic): Upgrade option offering tighter tolerance (±0.1%) and AEC-Q200 automotive qualification. Suitable for applications requiring enhanced precision and automotive-grade reliability. 5985 units in stock.

RG3216P-91R0-B-T1 (Susumu): Manufacturer-recommended substitute combining AEC-Q200 automotive qualification with anti-sulfur protection. Tighter tolerance (±0.1%) and lowest seated height (0.020" vs. 0.026"-0.028"). 2511 units in stock.

Selection between substitute parts depends on application requirements: standard applications use the original YAGEO part; automotive or high-precision applications benefit from either Panasonic or Susumu alternatives.

Frequently Asked Questions (FAQ)

Q: Can ERA-8AEB910V replace RT1206DRD0791RL directly? A: Yes. Both parts share identical resistance (91 Ohms), power rating (0.25W), package (1206), and operating temperature range (-55°C ~ 155°C). ERA-8AEB910V offers superior tolerance (±0.1% vs. ±0.5%) and AEC-Q200 certification, making it a direct upgrade.

Q: What is the difference between the two substitute parts? A: Both ERA-8AEB910V and RG3216P-91R0-B-T1 provide ±0.1% tolerance and AEC-Q200 qualification. RG3216P-91R0-B-T1 includes anti-sulfur protection and has a lower seated height (0.020" vs. 0.028"), which may be advantageous in space-constrained designs.

Q: Are there any mechanical compatibility issues when substituting? A: All three parts use the 1206 (3216 Metric) package with identical footprints. Minor dimensional variations (length 3.10mm vs. 3.20mm, height 0.65mm vs. 0.70mm vs. 0.50mm) are within standard PCB design tolerances and do not affect placement or soldering.

Q: Which substitute part is recommended for automotive applications? A: Both ERA-8AEB910V and RG3216P-91R0-B-T1 carry AEC-Q200 certification. RG3216P-91R0-B-T1 is designated as the manufacturer-recommended option and includes anti-sulfur protection for enhanced reliability in harsh automotive environments.

Q: Does tolerance affect circuit performance? A: Tolerance determines the maximum deviation from the nominal 91 Ohm value. The original part allows ±0.455 Ohms (±0.5%), while substitutes allow ±0.091 Ohms (±0.1%). Applications requiring tighter resistance control benefit from the substitute parts' superior tolerance.

Q: Are all parts RoHS3 compliant? A: Yes. RT1206DRD0791RL, ERA-8AEB910V, and RG3216P-91R0-B-T1 are all ROHS3 compliant with MSL rating 1 (Unlimited), suitable for standard manufacturing and storage conditions.
