Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RK73H1HTTC2671F is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Resistance value: 2.67 kOhms (exact match required)
• Tolerance: ±1% (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)
• Number of terminations: 2 (exact match required)

Compliance & Environmental Parameters:

• AEC-Q200 automotive qualification (required for automotive applications)
• RoHS3 compliance (required for regulatory conformance)
• Moisture Sensitivity Level: MSL 1 (required for storage and handling compatibility)

Substitute parts must satisfy all parameters listed above. Deviations in any parameter disqualify a part from direct substitution.

Parameter Comparison

Engineering Selection Recommendations

RK73H1HTTCM2671F (KOA Speer Electronics, Inc.)

This part is the manufacturer-recommended substitute from KOA Speer Electronics, Inc. It maintains identical electrical specifications and package configuration to the main part. The primary distinction is active product status, indicating ongoing manufacturer support and availability. This part is suitable for applications requiring continued supply from the original manufacturer. Note that moisture resistance is not explicitly specified for this variant, which may be a consideration for high-humidity or moisture-prone environments.

AC0201FR-072K67L (YAGEO)

This part is a direct cross-reference from YAGEO and provides an alternative sourcing option from a different manufacturer. It matches all critical electrical and mechanical parameters, including explicit moisture-resistant construction. The part maintains active product status and full AEC-Q200 automotive qualification. This option is suitable for applications requiring multi-source qualification or alternative supplier relationships while maintaining equivalent performance and compliance.

Both substitute parts satisfy the electrical, mechanical, and compliance requirements for direct substitution with the RK73H1HTTC2671F. Selection between them should be based on supply chain requirements, sourcing preferences, and specific application environmental conditions.

Frequently Asked Questions (FAQ)

Q: Can RK73H1HTTCM2671F be used as a direct replacement for RK73H1HTTC2671F?

A: Yes. Both parts share identical resistance (2.67 kOhms), tolerance (±1%), power rating (0.05W), package (0201), composition (thick film), temperature coefficient (±200ppm/°C), operating temperature range (-55°C ~ 155°C), AEC-Q200 rating, RoHS3 compliance, and MSL 1 rating. The primary difference is product status; RK73H1HTTCM2671F is active while the main part is not for new designs.

Q: Can AC0201FR-072K67L be used as a direct replacement for RK73H1HTTC2671F?

A: Yes. AC0201FR-072K67L meets all electrical and mechanical specifications required for substitution, including resistance, tolerance, power rating, package, composition, temperature coefficient, operating temperature range, AEC-Q200 rating, RoHS3 compliance, and MSL 1 rating. Additionally, moisture resistance is explicitly specified for this part.

Q: What are the critical parameters that determine substitution compatibility?

A: Substitution compatibility is determined by exact equivalence in resistance value (2.67 kOhms), tolerance (±1%), power rating (0.05W), package type (0201), composition (thick film), temperature coefficient (±200ppm/°C), operating temperature range (-55°C ~ 155°C), AEC-Q200 automotive qualification, RoHS3 compliance, and MSL 1 rating. Deviation in any of these parameters disqualifies a part from direct substitution.

Q: Are there differences in moisture resistance between the substitute parts?

A: Yes. The main part RK73H1HTTC2671F and AC0201FR-072K67L both explicitly specify moisture-resistant construction. RK73H1HTTCM2671F does not include moisture resistance in its specification. For applications in high-humidity or moisture-prone environments, AC0201FR-072K67L or the main part are preferred.

Q: What does "Not For New Designs" mean for the main part?

A: "Not For New Designs" indicates that KOA Speer Electronics, Inc. has superseded this part in their product line. While existing inventory may be available, the manufacturer recommends using active alternatives for new designs. RK73H1HTTCM2671F is the manufacturer's active equivalent.

Q: Are all substitute parts AEC-Q200 qualified?

A: Yes. Both RK73H1HTTCM2671F and AC0201FR-072K67L carry AEC-Q200 automotive qualification, matching the main part. This qualification is maintained across all substitute options.

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

A: Yes, provided the specific environmental and moisture requirements of the application are considered. All parts meet AEC-Q200 automotive qualification. For applications requiring moisture resistance, AC0201FR-072K67L or the main part are appropriate. For applications where moisture resistance is not specified, all three parts are suitable.
