Key Parameters

Substitute Part Grouping Explanation

Substitution for the 9T04021A16R9DAHF3 is determined by the following critical parameters:

• Resistance value: 16.9 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)

All identified substitute parts match these core electrical and mechanical specifications. Variations in temperature coefficient and product status are noted but do not affect functional interchangeability within the specified operating parameters.

Parameter Comparison

Engineering Selection Recommendations

RT0402DRD0716R9L (YAGEO): This substitute maintains YAGEO series continuity with active product status. It offers improved temperature coefficient performance (±25ppm/°C versus ±100ppm/°C) and achieves ROHS3 compliance. Tape & Reel packaging supports automated assembly processes. This part is suitable for applications requiring enhanced regulatory compliance and tighter temperature stability.

RG1005R-16R9-D-T10 (Susumu): This substitute provides AEC-Q200 automotive qualification and anti-sulfur composition, making it suitable for automotive and harsh environment applications. It maintains the original temperature coefficient specification (±100ppm/°C) and achieves ROHS3 compliance. Maximum seated height is 0.016" (0.40mm), which is 0.001" higher than the main part; verify PCB layout clearance before selection. Tape & Reel packaging supports automated assembly.

Both substitutes are functionally equivalent within the specified electrical and mechanical parameters. Selection depends on application requirements regarding regulatory compliance, environmental conditions, and assembly methodology.

Frequently Asked Questions (FAQ)

Q: Can RT0402DRD0716R9L directly replace 9T04021A16R9DAHF3 in existing designs?

A: Yes. Both parts share identical resistance (16.9 Ohms), tolerance (±0.5%), power rating (0.063W), package (0402), and operating temperature range (-55°C ~ 155°C). The improved temperature coefficient (±25ppm/°C) of RT0402DRD0716R9L provides enhanced stability without affecting interchangeability.

Q: What is the difference between RG1005R-16R9-D-T10 and the other substitutes?

A: RG1005R-16R9-D-T10 is manufactured by Susumu and includes AEC-Q200 automotive qualification with anti-sulfur composition. Its maximum seated height is 0.016" (0.40mm) compared to 0.014" (0.35mm) for YAGEO parts. Verify PCB layout clearance for height compatibility. Temperature coefficient matches the original part at ±100ppm/°C.

Q: Are all substitutes RoHS compliant?

A: RT0402DRD0716R9L and RG1005R-16R9-D-T10 are both ROHS3 compliant. The original 9T04021A16R9DAHF3 is RoHS non-compliant. If RoHS compliance is required, use either substitute.

Q: What packaging formats are available?

A: The original 9T04021A16R9DAHF3 is supplied in bulk packaging. Both substitutes (RT0402DRD0716R9L and RG1005R-16R9-D-T10) are available in Tape & Reel (TR) format, which is standard for automated assembly processes.

Q: Can I use RG1005R-16R9-D-T10 in non-automotive applications?

A: Yes. RG1005R-16R9-D-T10 meets all electrical and mechanical requirements for general-purpose applications. AEC-Q200 qualification indicates enhanced reliability and is not restrictive to automotive use.
