Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RK73H1HTTC6802D is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Resistance value: 68 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 to 155°C (exact match required)

Mechanical Parameters:

• Package: 0201 (0603 Metric) (exact match required)
• Composition: Thick Film (exact match required)
• Number of terminations: 2 (exact match required)
• Physical dimensions: 0.024" L x 0.012" W / 0.60mm x 0.30mm (exact match required)
• Height seated maximum: 0.010" / 0.26mm (exact match required)

Compliance & Certification:

• Automotive AEC-Q200 qualification (required for automotive applications)
• RoHS3 compliance (required for regulatory conformance)
• Moisture Sensitivity Level 1 (required for reliability)

The RK73H1HTTCM6802D meets all substitution criteria and is classified as the manufacturer-recommended equivalent.

Parameter Comparison

Engineering Selection Recommendations

The RK73H1HTTCM6802D is the direct equivalent substitute for the RK73H1HTTC6802D. Both parts are manufactured by KOA Speer Electronics, Inc., within the RK73H series, and share identical electrical, mechanical, and compliance specifications.

Selection Basis:

The primary distinction between the main part and substitute is product lifecycle status. The RK73H1HTTC6802D carries "Not For New Designs" designation, indicating manufacturer discontinuation from active production. The RK73H1HTTCM6802D maintains "Active" status, confirming ongoing manufacturing support and supply availability.

All critical parameters are identical:

• Electrical specifications (68 kOhms ±0.5%, 0.05W, ±200ppm/°C, -55°C to 155°C)
• Mechanical form factor (0201 package, 0.60mm x 0.30mm, 0.26mm height)
• Automotive qualification (AEC-Q200)
• Regulatory compliance (ROHS3, REACH Unaffected)
• Reliability rating (MSL 1 - Unlimited)

For new designs and ongoing production, the RK73H1HTTCM6802D is the appropriate selection. For existing designs currently using the RK73H1HTTC6802D, direct substitution is electrically and mechanically compatible without circuit modification or re-qualification.

Frequently Asked Questions (FAQ)

Q: Can the RK73H1HTTCM6802D be used as a direct replacement for the RK73H1HTTC6802D in existing designs?

A: Yes. The RK73H1HTTCM6802D is electrically and mechanically identical to the RK73H1HTTC6802D. All electrical parameters (resistance, tolerance, power rating, temperature coefficient, operating range) and mechanical specifications (package, dimensions, terminations) are equivalent. Direct substitution requires no circuit changes or re-qualification.

Q: What is the difference between these two part numbers?

A: The primary difference is product lifecycle status. The RK73H1HTTC6802D is designated "Not For New Designs," indicating it has been superseded. The RK73H1HTTCM6802D carries "Active" status, confirming current manufacturing and supply availability. The "M" designation in the part number reflects the active product variant within the RK73H series.

Q: Are both parts AEC-Q200 qualified for automotive applications?

A: Yes. Both the RK73H1HTTC6802D and RK73H1HTTCM6802D carry AEC-Q200 automotive qualification and are suitable for automotive circuit applications requiring this certification.

Q: What is the moisture sensitivity level for these resistors?

A: Both parts have Moisture Sensitivity Level (MSL) 1, which indicates unlimited shelf life without moisture control requirements. These components do not require special moisture-barrier packaging or desiccant storage.

Q: Are these parts RoHS compliant?

A: Yes. Both parts are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic component manufacturing and use.

Q: Can I use a different resistance value or tolerance as a substitute?

A: No. Substitution is limited to parts with identical resistance (68 kOhms) and tolerance (±0.5%). Different resistance values or tolerances will alter circuit performance and are not acceptable substitutes.

Q: Is the 0201 package the same as 0603 metric?

A: Yes. The 0201 package designation and 0603 metric designation refer to the same physical form factor: 0.60mm length x 0.30mm width. Both designations are used interchangeably in industry documentation.

Q: What is the temperature coefficient specification, and why does it matter?

A: The temperature coefficient is ±200ppm/°C for both parts, meaning the resistance value changes by a maximum of 200 parts per million for each degree Celsius change in operating temperature. This specification is critical for precision circuits operating across wide temperature ranges, particularly in automotive applications with -55°C to 155°C operating range.
