Substitute Part Grouping Explanation

Substitution for the 9T04021A30R9DAHF3 is determined by the following critical parameters:

• Resistance value: 30.9 Ohms
• Tolerance: ±0.5%
• Power rating: 0.063W (1/16W)
• Package: 0402 (1005 Metric)
• Composition: Thin Film
• Operating temperature range: -55°C ~ 155°C
• Moisture sensitivity level: 1 (Unlimited)

The identified substitute parts maintain these core electrical and mechanical specifications, ensuring functional equivalence in circuit applications. Variations in temperature coefficient and product status are noted but do not affect substitutability for standard applications.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts maintain full electrical and mechanical compatibility with the original 9T04021A30R9DAHF3 specification.

RT0402DRD0730R9L (YAGEO) is an active product with ROHS3 compliance and improved temperature coefficient performance (±25ppm/°C versus ±100ppm/°C). This part is suitable for applications requiring enhanced temperature stability and regulatory compliance.

RG1005R-30R9-D-T10 (Susumu) is an active product with ROHS3 compliance, anti-sulfur properties, and AEC-Q200 automotive qualification. This part is suitable for automotive and harsh environment applications where extended reliability and corrosion resistance are required.

Selection between substitute parts should be based on application requirements, regulatory compliance mandates, and environmental operating conditions.

Frequently Asked Questions (FAQ)

Q: Can RT0402DRD0730R9L directly replace 9T04021A30R9DAHF3?

A: Yes. Both parts share identical resistance (30.9 Ohms), tolerance (±0.5%), power rating (0.063W), and package (0402). The RT0402DRD0730R9L is an active product with improved specifications and ROHS3 compliance.

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

A: RT0402DRD0730R9L (YAGEO) offers a lower temperature coefficient (±25ppm/°C) and standard thin film construction. RG1005R-30R9-D-T10 (Susumu) includes anti-sulfur properties and AEC-Q200 automotive qualification, making it suitable for automotive and corrosive environments.

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

A: Yes. Both substitute parts are supplied in Tape & Reel (TR) packaging, identical to the original part.

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

A: The height difference is minimal (0.35mm for 9T04021A30R9DAHF3 and RT0402DRD0730R9L versus 0.40mm for RG1005R-30R9-D-T10). This variation is within standard PCB assembly tolerances and does not affect placement or soldering processes.

Q: Are both substitute parts RoHS compliant?

A: Yes. Both RT0402DRD0730R9L and RG1005R-30R9-D-T10 are ROHS3 compliant, whereas the original 9T04021A30R9DAHF3 is RoHS non-compliant.
