Qualifying Parameters for Substitution:

• Resistance value: 33 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)
• MSL rating: 1 (Unlimited) (exact match required)

All identified substitute parts meet these criteria without exception. Substitutes are grouped by manufacturer and product status to facilitate procurement decisions.

Engineering Selection Recommendations

RK73H1HTTCM3302F (KOA Speer Electronics, Inc.)

This part is the manufacturer-recommended substitute. It is electrically and mechanically identical to the RK73H1HTTC3302F across all specified parameters. The RK73H1HTTCM3302F carries Active product status, ensuring continued manufacturer support and availability for future procurement. This part is the preferred choice for applications requiring KOA Speer sourcing continuity and long-term supply assurance.

AC0201FR-0733KL (YAGEO)

This part is a direct cross-reference substitute from YAGEO. It meets all electrical and mechanical specifications of the RK73H1HTTC3302F, including AEC-Q200 automotive qualification, thick film composition, and identical package dimensions. The AC0201FR-0733KL carries Active product status and maintains higher inventory availability (12,759 Pcs). This part is suitable for applications where multi-source qualification is acceptable and where YAGEO supply chain access is preferred.

Both substitute parts are ROHS3 compliant, MSL 1 rated, and operate across the full -55°C to 155°C temperature range with ±200ppm/°C temperature coefficient performance.

Frequently Asked Questions (FAQ)

Q: Can RK73H1HTTCM3302F be used as a direct replacement for RK73H1HTTC3302F?

A: Yes. The RK73H1HTTCM3302F is electrically and mechanically identical to the RK73H1HTTC3302F. Both components share the same resistance value (33 kOhms), tolerance (±1%), power rating (0.05W), package (0201), composition (thick film), temperature coefficient (±200ppm/°C), operating range (-55°C ~ 155°C), and AEC-Q200 automotive qualification. The primary difference is product status: RK73H1HTTCM3302F is Active, while RK73H1HTTC3302F is Not For New Designs.

Q: Is AC0201FR-0733KL compatible with RK73H1HTTC3302F applications?

A: Yes. The AC0201FR-0733KL meets all electrical and mechanical parameters of the RK73H1HTTC3302F. Both components are 33 kOhms ±1%, 0.05W, 0201 package, thick film, AEC-Q200 rated, moisture resistant, ROHS3 compliant, and MSL 1 rated. The AC0201FR-0733KL is manufactured by YAGEO and carries Active product status.

Q: What are the key parameters that determine substitutability?

A: Substitutability is determined by exact matching of: resistance value (33 kOhms), tolerance (±1%), power rating (0.05W), package type (0201), composition (thick film), temperature coefficient (±200ppm/°C), operating temperature range (-55°C ~ 155°C), automotive qualification (AEC-Q200), moisture resistance, RoHS compliance (ROHS3), and MSL rating (1). All three parts match these parameters without deviation.

Q: Are there any packaging differences between these parts?

A: All three parts use the 0201 package (0603 Metric) with identical physical dimensions: 0.024" L x 0.012" W (0.60mm x 0.30mm) and maximum seated height of 0.010" (0.26mm). Packaging format differences exist only in tape & reel configuration, which does not affect component performance or PCB assembly compatibility.

Q: Which substitute part should be selected for new production?

A: For new production, select either RK73H1HTTCM3302F (KOA Speer) or AC0201FR-0733KL (YAGEO), as both carry Active product status. The RK73H1HTTCM3302F maintains manufacturer continuity with the original part source. The AC0201FR-0733KL offers higher inventory availability and multi-source qualification benefits.

Q: Are all three parts AEC-Q200 qualified?

A: Yes. The RK73H1HTTC3302F, RK73H1HTTCM3302F, and AC0201FR-0733KL all carry AEC-Q200 automotive qualification ratings, making them suitable for automotive and high-reliability applications.

Q: What is the MSL rating for these components?

A: All three parts are rated MSL 1 (Unlimited), indicating unlimited shelf life without moisture bake-out requirements prior to soldering.
