Key Parameters

Substitute Part Grouping Explanation

Substitution of the RK73H1HTTC6983D is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Resistance value: 698 kOhms (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 / Case: 0201 (0603 Metric) (exact match required)
• Composition: Thick Film (exact match required)

Compliance & Certification:

• Automotive AEC-Q200 qualification (exact match required)
• RoHS3 compliance (exact match required)
• Moisture Sensitivity Level MSL 1 (exact match required)

Substitute parts must maintain identical electrical performance, physical dimensions, and automotive qualification standards. The RK73H series designation indicates parts within the same product family and manufacturing process.

Parameter Comparison

Engineering Selection Recommendations

The RK73H1HTTCM6983D is the direct equivalent substitute for the RK73H1HTTC6983D. Both parts are manufactured by KOA Speer Electronics, Inc., within the RK73H series and share identical electrical specifications, mechanical dimensions, and automotive compliance certifications.

The primary distinction is product status: the original RK73H1HTTC6983D is designated "Not For New Designs," while the RK73H1HTTCM6983D maintains "Active" status in the manufacturer's current product portfolio. This status change reflects the manufacturer's ongoing product line management and does not indicate any functional or performance difference between the two parts.

Both parts satisfy AEC-Q200 automotive qualification requirements, maintain ROHS3 compliance, and carry MSL 1 moisture sensitivity rating. The substitute part is suitable for direct replacement in existing designs and for new applications requiring 698 kOhms ±0.5% 0.05W 0201 chip resistors with automotive-grade specifications.

Frequently Asked Questions (FAQ)

Q: Can the RK73H1HTTCM6983D be used as a direct replacement for the RK73H1HTTC6983D?

A: Yes. The RK73H1HTTCM6983D is electrically and mechanically identical to the RK73H1HTTC6983D. Both parts have the same resistance value (698 kOhms), tolerance (±0.5%), power rating (0.05W), package (0201), temperature coefficient (±200ppm/°C), operating temperature range (-55°C ~ 155°C), and AEC-Q200 automotive qualification. Direct substitution is valid.

Q: Why is the original part marked "Not For New Designs"?

A: The "Not For New Designs" status indicates the manufacturer has transitioned this part to end-of-life management. The RK73H1HTTCM6983D represents the active equivalent in the current product line. This is a standard lifecycle management practice and does not reflect any technical deficiency in the original part.

Q: Are there any differences in moisture resistance between these parts?

A: No. Both parts feature moisture-resistant thick film construction and carry identical MSL 1 (Unlimited) moisture sensitivity ratings. Moisture handling and storage requirements are identical.

Q: Can these parts be used interchangeably in automotive applications?

A: Yes. Both parts meet AEC-Q200 automotive qualification standards and are suitable for automotive circuit applications. The electrical and mechanical specifications required for automotive reliability are identical between the two parts.

Q: What is the significance of the "M" in the substitute part number?

A: The "M" designation in RK73H1HTTCM6983D indicates a variant within the RK73H series. This designation reflects the manufacturer's internal product coding but does not alter the functional equivalence or performance characteristics of the component.

Q: Are there any compliance or certification differences?

A: No. Both parts are ROHS3 compliant, REACH unaffected, and carry identical regulatory certifications. Compliance status is equivalent for both parts.
