Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 9T04021A64R9DAHF3 is determined by the following mandatory parameters:

• Resistance Value: 64.9 Ohms (exact match required)
• Tolerance: ±0.5% or better (tighter tolerance acceptable)
• Power Rating: 0.063W minimum (1/16W)
• Package: 0402 (1005 Metric) form factor
• Composition: Thin Film technology
• Termination Count: 2 terminations
• Moisture Sensitivity: MSL 1 or better

Substitute parts are categorized as direct replacements when all electrical and mechanical parameters align within these specifications. An upgrade classification applies when tolerance or temperature coefficient performance exceeds the original part's specifications while maintaining all other compatibility criteria.

Parameter Comparison

Engineering Selection Recommendations

RT0402DRD0764R9L (YAGEO) is the primary direct substitute. This part maintains identical electrical specifications and physical dimensions while offering active product status and ROHS3 compliance. The improved temperature coefficient (±25ppm/°C versus ±100ppm/°C) provides enhanced stability without compromising compatibility.

RR0510R-64R9-D (Susumu) serves as an alternative direct substitute with active status and ROHS3 compliance. Physical height increases to 0.016" (0.40mm) and operating temperature maximum reduces to 125°C. These parameters remain within acceptable substitution criteria for most applications.

TNPW040264R9BETD (Vishay Dale) functions as an upgrade option, delivering superior tolerance performance (±0.1% versus ±0.5%) and improved temperature coefficient (±25ppm/°C). This part carries military-grade specifications. Operating temperature maximum is 125°C, and RoHS compliance status differs from the main part. Selection of this upgrade is appropriate when enhanced precision is required.

Frequently Asked Questions (FAQ)

Q: Can RT0402DRD0764R9L replace 9T04021A64R9DAHF3 in all applications?

A: Yes. RT0402DRD0764R9L maintains all critical electrical parameters (64.9 Ohms ±0.5%, 0.063W) and physical dimensions (0402 package, 0.014" max height). The improved temperature coefficient provides additional performance margin.

Q: What is the difference between direct substitutes and the upgrade part?

A: Direct substitutes (RT0402DRD0764R9L and RR0510R-64R9-D) match the original tolerance specification of ±0.5%. The upgrade part (TNPW040264R9BETD) offers tighter tolerance (±0.1%) and improved temperature stability, suitable for precision applications requiring enhanced accuracy.

Q: Does the height difference between parts affect PCB layout?

A: The main part and RT0402DRD0764R9L both have 0.014" (0.35mm) maximum seated height. RR0510R-64R9-D and TNPW040264R9BETD increase to 0.016" (0.40mm). Verify clearance in your specific PCB design if height-constrained applications are present.

Q: Are all substitute parts RoHS compliant?

A: RT0402DRD0764R9L and RR0510R-64R9-D are ROHS3 compliant. TNPW040264R9BETD is RoHS non-compliant, matching the original part's status. Compliance requirements depend on your application and regional regulations.

Q: What is the operating temperature limitation for RR0510R-64R9-D?

A: RR0510R-64R9-D operates from -55°C to 125°C, compared to the original part's -55°C to 155°C range. Confirm your application does not require operation above 125°C before selection.

Q: Can TNPW040264R9BETD be used in cost-sensitive applications?

A: TNPW040264R9BETD is classified as an upgrade part with military-grade specifications and tighter tolerance. Use this part only when precision requirements justify the additional cost and performance characteristics.
