Substitute Part Grouping Explanation

Substitution of the RK73H1HTTC6980D is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Resistance value: 698 Ohms (exact match required)
• Tolerance: ±0.5% (exact match required)
• Power rating: 0.05W / 1/20W (exact match required)
• Temperature coefficient: ±200ppm/°C (exact match required)
• Operating temperature range: -55°C ~ 155°C (exact match required)

Mechanical Parameters:

• Package type: 0201 (0603 Metric) (exact match required)
• Composition: Thick Film (exact match required)

Compliance & Certification:

• Automotive qualification: AEC-Q200 (exact match required)
• RoHS compliance: ROHS3 (exact match required)
• Moisture sensitivity: MSL 1 (exact match required)

The RK73H1HTTCM6980D qualifies as a direct substitute based on identical electrical specifications, mechanical dimensions, and automotive certifications. The primary distinction is product status: the original part is obsolete for new designs, while the substitute is active.

Parameter Comparison

Engineering Selection Recommendations

The RK73H1HTTCM6980D is the direct equivalent for the RK73H1HTTC6980D. Both parts are manufactured by KOA Speer Electronics, Inc., and share identical electrical, mechanical, and thermal specifications. The substitute part maintains full AEC-Q200 automotive qualification and ROHS3 compliance.

The primary advantage of selecting RK73H1HTTCM6980D is its active product status, ensuring long-term availability and supply chain continuity. The original part's "Not For New Designs" classification indicates end-of-life status, making the substitute the appropriate choice for new production, field replacements, and ongoing inventory management.

Both parts are functionally interchangeable in all circuit applications requiring a 698 Ohm ±0.5% resistor with automotive-grade reliability in a 0201 package.

Frequently Asked Questions (FAQ)

Q: Can RK73H1HTTCM6980D be used as a direct replacement for RK73H1HTTC6980D?

A: Yes. Both parts are electrically and mechanically identical with matching resistance values (698 Ohms ±0.5%), power ratings (0.05W), package dimensions (0201), temperature coefficients (±200ppm/°C), and AEC-Q200 automotive certifications.
