9T06031A3830BBHFT Equivalent & Substitute Parts

Part Overview

The 9T06031A3830BBHFT is a 383 Ohms ±0.1% thin film chip resistor manufactured by YAGEO in 0603 (1608 Metric) package format with 0.1W power rating. This part is classified as obsolete, making equivalent and substitute components necessary for ongoing production and maintenance applications. The thin film construction and tight tolerance specification support precision analog circuit applications requiring stable resistance values across temperature ranges from -55°C to 155°C.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 9T06031A3830BBHFT is determined by the following critical parameters:

• Resistance Value: Must be 383 Ohms
• Tolerance: Must be ±0.1% or tighter
• Power Rating: Must be 0.1W or greater
• Package Type: Must be 0603 (1608 Metric)
• Composition: Must be thin film construction
• Operating Temperature Range: Must support -55°C to 155°C minimum

The substitute parts listed below meet all these criteria and are therefore electrically and mechanically interchangeable with the main part number.

Parameter Comparison

Engineering Selection Recommendations

RT0603BRE07383RL is the primary direct substitute. This YAGEO part maintains identical electrical specifications while offering active product status and ROHS3 compliance. The lower temperature coefficient (±50ppm/°C versus ±100ppm/°C) provides improved stability across the operating temperature range. Tape & Reel packaging supports automated assembly processes.

TNPW0603383RBETA is an upgrade substitute manufactured by Vishay Dale. This military-grade thin film resistor features the lowest temperature coefficient (±25ppm/°C) and is suitable for applications requiring enhanced precision and stability. The operating temperature range is limited to -55°C ~ 125°C, which is acceptable for most applications but does not extend to the full 155°C upper limit of the original part. Tape & Reel packaging is standard.

Both substitute parts are electrically and mechanically compatible with the 9T06031A3830BBHFT and support direct board-level replacement without circuit modification.

Frequently Asked Questions (FAQ)

Q: Can RT0603BRE07383RL be used as a direct replacement for 9T06031A3830BBHFT?

A: Yes. Both parts share identical resistance (383 Ohms), tolerance (±0.1%), power rating (0.1W), and package format (0603). The RT0603BRE07383RL is electrically and mechanically interchangeable and offers the advantage of active product status.

Q: What is the difference between the temperature coefficients of these parts?

A: The 9T06031A3830BBHFT has a temperature coefficient of ±100ppm/°C, while RT0603BRE07383RL is ±50ppm/°C and TNPW0603383RBETA is ±25ppm/°C. Lower temperature coefficients indicate better resistance stability across temperature variations. For precision applications, the lower coefficient values provide improved performance.

Q: Is TNPW0603383RBETA suitable for applications requiring operation at 155°C?

A: No. The TNPW0603383RBETA is rated for -55°C ~ 125°C operation. If the application requires sustained operation at temperatures above 125°C, this part is not suitable. The RT0603BRE07383RL supports the full -55°C ~ 155°C range.

Q: What is the significance of RoHS compliance status?

A: RoHS compliance indicates the part meets restrictions on hazardous substances. The RT0603BRE07383RL is ROHS3 compliant, making it suitable for applications subject to RoHS regulations. The original part and TNPW0603383RBETA are RoHS non-compliant and may not be acceptable for regulated applications.

Q: Are the physical dimensions identical across all three parts?

A: The length and height are identical (0.063" L × 0.022" H). The TNPW0603383RBETA has a slightly wider dimension (0.033" W versus 0.031" W), but this remains within standard 0603 package specifications and does not affect PCB footprint compatibility.

Q: What packaging formats are available?

A: The original 9T06031A3830BBHFT is supplied in bulk packaging. Both substitute parts (RT0603BRE07383RL and TNPW0603383RBETA) are supplied in Tape & Reel (TR) format, which is standard for automated assembly operations.
