Key Parameters

Substitute Part Grouping Explanation

Substitution for the 9T12062A25R5BAHFT is determined by the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 25.5 Ohms
• Tolerance: ±0.1%
• Package / Case: 1206 (3216 Metric)
• Composition: Thin Film
• Number of Terminations: 2

Allowable Variations:

• Power rating may be equal or higher (0.125W minimum required)
• Operating temperature range may be equal or narrower
• Temperature coefficient may be equal or lower (tighter tolerance acceptable)
• Product status may transition from obsolete to active
• RoHS compliance may improve

Two substitute parts meet these criteria with enhanced specifications and active product status.

Engineering Selection Recommendations

RT1206BRD0725R5L (Direct Substitute): This YAGEO part is the primary direct substitute. It maintains the same manufacturer lineage, identical resistance and tolerance specifications, and identical package dimensions. The power rating increase from 0.125W to 0.25W provides design margin without affecting electrical performance. The improved temperature coefficient (±25ppm/°C vs. ±100ppm/°C) enhances stability. Active product status ensures long-term availability. ROHS3 compliance satisfies modern regulatory requirements. This part is suitable for direct replacement in existing designs.

TNPW120625R5BETA (Upgrade Substitute): This Vishay Dale military-grade thin film resistor offers the same resistance, tolerance, and package specifications with identical power rating upgrade to 0.25W. The military classification and ±25ppm/°C temperature coefficient provide enhanced performance characteristics. Operating temperature range is limited to -55°C ~ 125°C compared to the original -55°C ~ 155°C specification. Active product status ensures availability. This part is suitable for applications requiring military-grade component specifications and enhanced reliability.

Frequently Asked Questions (FAQ)

Q: Can RT1206BRD0725R5L be used as a direct replacement for 9T12062A25R5BAHFT?

A: Yes. Both parts share identical resistance (25.5 Ohms), tolerance (±0.1%), package (1206), and physical dimensions. The higher power rating (0.25W vs. 0.125W) is compatible with the original design and provides additional thermal margin.

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

A: RT1206BRD0725R5L is manufactured by YAGEO (same as the original) and is ROHS3 compliant. TNPW120625R5BETA is manufactured by Vishay Dale with military-grade specifications. Both offer identical electrical performance for the 25.5 Ohm resistance value. The primary difference is manufacturer, military classification, and regulatory compliance status.

Q: Is the operating temperature range difference between the main part and TNPW120625R5BETA significant?

A: The TNPW120625R5BETA operates from -55°C to 125°C, while the original operates to 155°C. This 30°C reduction at the upper limit should be evaluated against your specific application requirements. If your design requires operation above 125°C, RT1206BRD0725R5L is the appropriate choice.

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

A: Yes. All three parts use the 1206 (3216 Metric) package with identical footprint dimensions (0.122" L x 0.063" W / 3.10mm x 1.60mm). Physical board layout compatibility is maintained.

Q: What does the improved temperature coefficient mean?

A: The substitute parts feature ±25ppm/°C compared to the original ±100ppm/°C. This means the resistance value changes less with temperature variations, providing improved stability and accuracy in temperature-sensitive applications.

Q: Can I use these substitutes in new designs?

A: Yes. Both substitute parts have active product status and are suitable for new designs. RT1206BRD0725R5L is recommended for standard applications. TNPW120625R5BETA is recommended for military or high-reliability applications.
