Substitute Part Grouping Explanation

Substitute parts for the RK73H1HTTC6802F are qualified based on strict electrical and mechanical parameter matching:

Qualifying Parameters for Substitution:

• Resistance value: 68 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)
• AEC-Q200 automotive qualification (required for automotive applications)
• Moisture resistance: Yes (required for reliability)
• RoHS3 compliance (required for regulatory conformance)
• MSL rating: 1 (Unlimited) (exact match required)

All identified substitute parts meet these criteria and are therefore electrically and mechanically interchangeable with the RK73H1HTTC6802F in applications requiring these specifications.

Frequently Asked Questions (FAQ)

Q: Can RK73H1HTTCM6802F be used as a direct replacement for RK73H1HTTC6802F?

A: Yes. The RK73H1HTTCM6802F is the manufacturer-recommended equivalent from KOA Speer Electronics, Inc. Both parts share identical resistance (68 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, and all compliance certifications. Physical dimensions and termination count are identical.

Q: Can AC0201FR-0768KL from YAGEO be used in place of the KOA RK73H1HTTC6802F?

A: Yes. The AC0201FR-0768KL meets all electrical and mechanical specifications of the RK73H1HTTC6802F. Both parts are 68 kOhms ±1%, 0.05W, 0201 package, thick film composition, with ±200ppm/°C temperature coefficient and -55°C ~ 155°C operating range. Both carry AEC-Q200 automotive qualification, ROHS3 compliance, and MSL 1 rating. Cross-manufacturer substitution is electrically and mechanically valid.

Q: What is the significance of the "Not For New Designs" status on RK73H1HTTC6802F?

A: "Not For New Designs" indicates that KOA Speer Electronics, Inc. has discontinued this specific part number for new design applications. Existing designs using this part number should transition to the active equivalent RK73H1HTTCM6802F for continued support and supply assurance. Both substitute parts listed carry Active status.

Q: Are all three parts suitable for automotive applications?

A: Yes. All three parts—RK73H1HTTC6802F, RK73H1HTTCM6802F, and AC0201FR-0768KL—carry AEC-Q200 automotive qualification and are rated for automotive operating conditions across -55°C to 155°C. All are moisture-resistant thick film resistors suitable for automotive and industrial environments.

Q: What is the difference between RK73H1HTTC6802F and RK73H1HTTCM6802F?

A: Both parts are manufactured by KOA Speer Electronics, Inc. and share identical electrical and mechanical specifications. The primary difference is product status: RK73H1HTTC6802F is "Not For New Designs," while RK73H1HTTCM6802F is Active. The RK73H1HTTCM6802F is the current production equivalent and is recommended for new designs and ongoing supply.

Q: Are there any packaging differences between these substitute parts?

A: All three parts use identical 0201 (0603 Metric) packaging with dimensions of 0.024" L x 0.012" W (0.60mm x 0.30mm) and maximum seated height of 0.010" (0.26mm). Both terminations are identical. No PCB layout or assembly modifications are required when substituting between these parts.

Q: What is MSL 1 (Unlimited) rating?

A: MSL 1 (Unlimited) indicates the component has unlimited shelf life and does not require special moisture-controlled storage or handling. All three parts carry this rating, eliminating moisture sensitivity concerns during storage and assembly.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All three parts—RK73H1HTTC6802F, RK73H1HTTCM6802F, and AC0201FR-0768KL—are ROHS3 compliant and meet regulatory requirements for restricted substance elimination.
