RK73H1HTTC2323F Equivalent & Substitute Parts

Part Overview

The RK73H1HTTC2323F is a 232 kOhms ±1% thick film chip resistor manufactured by KOA Speer Electronics, Inc., rated at 0.05W (1/20W) in a 0201 (0603 Metric) package. This component is designed for automotive applications and meets AEC-Q200 qualification standards with moisture-resistant construction.

The RK73H1HTTC2323F carries a "Not For New Designs" product status, indicating it has been superseded in the manufacturer's active product line. Identifying equivalent and substitute parts is necessary to ensure design continuity, maintain supply chain flexibility, and transition to actively supported alternatives where applicable.

Substitute Part Grouping Explanation

Substitute parts for the RK73H1HTTC2323F are qualified based on the following electrical and mechanical parameters:

Substitution Criteria:

• Resistance value: 232 kOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 0.05W / 1/20W (exact match required)
• Package: 0201 (0603 Metric) (exact match required)
• Composition: Thick Film (exact match required)
• Temperature coefficient: ±200ppm/°C (exact match required)
• Operating temperature range: -55°C ~ 155°C (exact match required)
• Automotive qualification: AEC-Q200 (exact match required)
• Moisture resistance: Present (exact match required)
• RoHS compliance: ROHS3 Compliant (exact match required)
• Moisture sensitivity: MSL 1 (exact match required)

Substitute parts must match all parameters listed above. Variations in manufacturer, series designation, or packaging format (Tape & Reel vs. bulk) do not affect electrical or mechanical compatibility when all core parameters are identical.

Engineering Selection Recommendations

RK73H1HTTCM2323F (KOA Speer Electronics, Inc.):

This part is the manufacturer-recommended successor within the KOA product line. It carries Active product status and maintains all electrical and mechanical specifications identical to the RK73H1HTTC2323F. The primary distinction is the absence of moisture-resistant construction in the detailed description. This part is suitable for applications where the original moisture-resistant feature is not a critical requirement and where continuity with the KOA manufacturer ecosystem is preferred.

AC0201FR-07232KL (YAGEO):

This part is a direct cross-reference alternative from YAGEO, maintaining all electrical and mechanical parameters including moisture-resistant construction. It carries Active product status and meets all AEC-Q200 automotive qualifications. This part is suitable for applications requiring an alternative manufacturer source while preserving the complete feature set of the original component, including moisture resistance.

Both substitute parts are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity ratings, ensuring compatibility with standard handling and storage protocols.

Frequently Asked Questions (FAQ)

Q: Can RK73H1HTTCM2323F be used as a direct replacement for RK73H1HTTC2323F?

A: RK73H1HTTCM2323F matches all electrical and mechanical parameters of the RK73H1HTTC2323F. However, the detailed description indicates the absence of moisture-resistant construction in the substitute. If moisture resistance is a design requirement, this part may not be suitable. If moisture resistance is not critical to the application, this part provides full electrical compatibility.

Q: What is the difference between RK73H1HTTC2323F and AC0201FR-07232KL?

A: Both parts are electrically and mechanically identical, with matching resistance, tolerance, power rating, package, temperature coefficient, operating range, and AEC-Q200 automotive qualification. Both include moisture-resistant construction. The primary difference is the manufacturer: KOA Speer Electronics, Inc. versus YAGEO. Both parts carry Active product status.

Q: Are all substitute parts available in the same packaging format?

A: RK73H1HTTC2323F and AC0201FR-07232KL are both supplied in Tape & Reel (TR) packaging. RK73H1HTTCM2323F packaging format is not specified in the provided data. Packaging format does not affect electrical or mechanical compatibility when all core parameters are identical.

Q: Do all substitute parts meet automotive AEC-Q200 standards?

A: Yes. RK73H1HTTCM2323F and AC0201FR-07232KL both carry AEC-Q200 automotive qualification ratings, matching the original RK73H1HTTC2323F specification.

Q: What is the significance of the "Not For New Designs" status on the original part?

A: This status indicates the RK73H1HTTC2323F has been superseded in the manufacturer's active product line. For new designs, RK73H1HTTCM2323F (KOA) or AC0201FR-07232KL (YAGEO) are the recommended alternatives, both carrying Active product status.

Q: Are all parts ROHS3 compliant?

A: Yes. RK73H1HTTC2323F, RK73H1HTTCM2323F, and AC0201FR-07232KL are all ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity ratings.
