Substitute Part Grouping Explanation

Substitute parts for the RK73H1HTTC3303F are qualified based on strict electrical and mechanical parameter matching:

Substitution Criteria:

• Resistance value: 330 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)

Parts meeting all these criteria are classified as direct electrical and mechanical equivalents and may be substituted without circuit redesign or board layout modification.

Parameter Comparison

Engineering Selection Recommendations

RK73H1HTTCM3303F (KOA Speer Electronics, Inc.): This part is the manufacturer-recommended substitute from KOA Speer Electronics, Inc. It maintains identical electrical and mechanical specifications to the main part while carrying an Active product status. This option is preferred for applications requiring continuity within the same manufacturer's product line and for new production runs.

AC0201FR-07330KL (YAGEO): This part is a direct cross-reference from YAGEO and meets all electrical and mechanical requirements. It carries an Active product status and is suitable for applications where multi-source qualification is required or where YAGEO components are preferred. This option provides supply chain diversification.

Both substitute parts are ROHS3 compliant, AEC-Q200 qualified, and maintain the same MSL rating as the original component. Selection between substitutes should be based on supply availability, procurement agreements, and established qualification protocols within the design organization.

Frequently Asked Questions (FAQ)

Q: Can RK73H1HTTCM3303F be used as a direct replacement for RK73H1HTTC3303F?

A: Yes. Both parts share identical electrical specifications (330 kOhms ±1%, 0.05W), mechanical dimensions (0201 package), temperature characteristics (±200ppm/°C, -55°C ~ 155°C), and automotive qualifications (AEC-Q200). The primary difference is product status: RK73H1HTTCM3303F is Active, while RK73H1HTTC3303F is Not For New Designs.

Q: Can AC0201FR-07330KL be used as a direct replacement for RK73H1HTTC3303F?

A: Yes. AC0201FR-07330KL meets all electrical and mechanical requirements: 330 kOhms ±1%, 0.05W, 0201 package, ±200ppm/°C temperature coefficient, -55°C ~ 155°C operating range, AEC-Q200 qualification, and ROHS3 compliance. The manufacturer differs (YAGEO vs. KOA Speer), but specifications are equivalent.

Q: Are there any packaging differences between these parts?

A: All three parts use the 0201 (0603 Metric) package 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). No board layout or footprint modifications are required when substituting between these parts.

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

A: This designation indicates that RK73H1HTTC3303F is in mature or end-of-life phase and is not recommended for new product development. However, it remains suitable for production support, field repairs, and design transitions. The substitute parts with Active status are recommended for new designs.

Q: Do all three parts have the same moisture sensitivity level?

A: Yes. All three parts carry MSL rating 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling. Standard component storage practices apply.

Q: Are there compliance or certification differences?

A: No. All three parts are ROHS3 compliant, AEC-Q200 qualified, REACH unaffected, and carry ECCN EAR99 classification. Compliance profiles are identical.
