9T12062A64R9DAHFT Equivalent & Substitute Parts

Part Overview

The 9T12062A64R9DAHFT is a 64.9 Ohm ±0.5% thin film chip resistor in 1206 (3216 Metric) package rated at 0.125W (1/8W) power dissipation. Manufactured by YAGEO under the RT series, this component is classified as obsolete. Due to its obsolete status and limited availability for new designs, equivalent and substitute parts from active product lines are necessary for ongoing production, maintenance, and new application development.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the 9T12062A64R9DAHFT is determined by the following critical parameters:

• Resistance Value: Must be 64.9 Ohms
• Tolerance: Must be ±0.5% or tighter
• Package: Must be 1206 (3216 Metric)
• Composition: Must be Thin Film
• Power Rating: Must be equal to or greater than 0.125W

The substitute parts identified meet these core electrical and mechanical requirements. Differences in power rating (upgrade to 0.25W), temperature coefficient, and product status are noted but do not prevent functional substitution in applications where the original part is used.

Parameter Comparison

Engineering Selection Recommendations

RT1206DRD0764R9L is the direct equivalent from YAGEO's active RT series. It maintains the same resistance and tolerance specifications while offering higher power rating (0.25W vs. 0.125W) and improved temperature coefficient (±25ppm/°C vs. ±100ppm/°C). This part is ROHS3 compliant and actively manufactured, making it suitable for new designs and production continuity.

TNPW120664R9BETA is an upgrade option from Vishay Dale's military-grade TNPW series. It provides tighter tolerance (±0.1% vs. ±0.5%), higher power rating (0.25W), and superior temperature coefficient (±25ppm/°C). This part is actively produced and suitable for applications requiring enhanced precision and reliability. Operating temperature range is limited to -55°C ~ 125°C compared to the original -55°C ~ 155°C specification.

Frequently Asked Questions (FAQ)

Q: Can RT1206DRD0764R9L directly replace 9T12062A64R9DAHFT?

A: Yes. Both parts share identical resistance (64.9 Ohms), tolerance (±0.5%), package (1206), and composition (thin film). The higher power rating (0.25W vs. 0.125W) and improved temperature coefficient of the RT1206DRD0764R9L provide enhanced performance margins without affecting circuit compatibility.

Q: What is the difference between the two substitute parts?

A: RT1206DRD0764R9L is a direct equivalent from YAGEO with matching tolerance. TNPW120664R9BETA is a military-grade upgrade from Vishay Dale with tighter tolerance (±0.1%), lower temperature coefficient, and active production status. TNPW120664R9BETA has a reduced upper operating temperature limit of 125°C versus 155°C.

Q: Are the substitute parts available in the same packaging?

A: Both substitute parts are supplied in Tape & Reel (TR) packaging, suitable for automated assembly. The original part packaging information was not specified in available data.

Q: Which substitute part should be selected for new designs?

A: RT1206DRD0764R9L is recommended for direct replacement in existing applications. TNPW120664R9BETA is recommended when enhanced precision (±0.1% tolerance) and superior temperature stability are required, provided the operating temperature range does not exceed 125°C.

Q: Are there RoHS compliance considerations?

A: RT1206DRD0764R9L is ROHS3 compliant. TNPW120664R9BETA is RoHS non-compliant. Application requirements for RoHS compliance should determine part selection.
