Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RK73H1HTTC6981D is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 6.98 kOhms
• Tolerance: ±0.5%
• Power rating: 0.05W (1/20W)
• Package format: 0201 (0603 Metric)
• Composition: Thick Film
• Temperature coefficient: ±200ppm/°C
• Operating temperature range: -55°C ~ 155°C
• Automotive qualification: AEC-Q200
• Moisture sensitivity level: 1 (Unlimited)
• RoHS compliance: ROHS3 Compliant

Parts meeting all these parameters are classified as direct electrical and mechanical equivalents. The primary distinction between the main part and substitute alternatives is product status and manufacturing continuity.

Parameter Comparison

Engineering Selection Recommendations

The RK73H1HTTCM6981D is the direct equivalent substitute for the RK73H1HTTC6981D. Both components are manufactured by KOA Speer Electronics, Inc. and share identical electrical and mechanical specifications across all critical parameters including resistance value, tolerance, power rating, package format, temperature coefficient, and operating temperature range.

The primary distinction is product lifecycle status. The RK73H1HTTC6981D is designated Not For New Designs, indicating end-of-life or transition status. The RK73H1HTTCM6981D maintains Active product status, ensuring continued manufacturing support and supply chain availability.

Both parts satisfy automotive AEC-Q200 qualification requirements and ROHS3 compliance mandates. Selection between these parts should be based on design phase and supply chain requirements: existing designs may continue using available inventory of the RK73H1HTTC6981D, while new designs should transition to the RK73H1HTTCM6981D for long-term production continuity.
