Key Parameters

Substitute Part Grouping Explanation

Substitution of the RK73H1HTTC4700F is determined by strict equivalence across the following electrical and mechanical parameters:

Electrical Parameters:

• Resistance value: 470 Ohms (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)

Compliance & Certification:

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

Substitute parts must match all parameters listed above. Identified substitutes are grouped into two categories: manufacturer-recommended alternatives and direct cross-reference equivalents from alternative suppliers.

Engineering Selection Recommendations

RK73H1HTTCM4700F (KOA Speer Electronics, Inc. - MFR Recommended):

This part is the manufacturer-recommended successor to the RK73H1HTTC4700F. It carries Active product status, indicating ongoing manufacturing support and availability. Both parts are from the same manufacturer (KOA Speer Electronics, Inc.) and share identical electrical specifications. The primary distinction is that RK73H1HTTCM4700F does not explicitly specify moisture resistance in its feature set, whereas the original part does. For applications requiring moisture-resistant thick film construction, this difference should be evaluated against specific environmental requirements. RoHS3 compliance and MSL 1 rating are maintained.

AC0201FR-07470RL (YAGEO - Direct Equivalent):

This part provides a direct cross-manufacturer equivalent from YAGEO. It matches all electrical and mechanical parameters of the original part, including explicit moisture-resistant thick film construction. The AC0201FR-07470RL carries Active product status with confirmed inventory availability. It maintains AEC-Q200 automotive certification, RoHS3 compliance, and MSL 1 rating. This part is suitable for direct substitution in applications where supplier diversification or YAGEO component standardization is required.

Selection Basis:

• For continued use of KOA Speer Electronics components: RK73H1HTTCM4700F
• For supplier diversification or YAGEO standardization: AC0201FR-07470RL
• Both substitutes maintain full automotive compliance and regulatory conformance
• All three parts are electrically and mechanically interchangeable within the specified parameters

Frequently Asked Questions (FAQ)

Q: Can RK73H1HTTCM4700F be used as a direct replacement for RK73H1HTTC4700F?

A: Yes. Both parts share identical electrical specifications (470 Ohms ±1%, 0.05W, ±200ppm/°C, -55°C ~ 155°C) and mechanical package (0201). The primary difference is that moisture resistance is not explicitly specified for RK73H1HTTCM4700F. If moisture resistance is a critical requirement for your application, this should be confirmed with the manufacturer before substitution.

Q: Is AC0201FR-07470RL from YAGEO fully compatible with the original KOA part?

A: Yes. AC0201FR-07470RL matches all electrical and mechanical parameters of RK73H1HTTC4700F, including resistance, tolerance, power rating, package, temperature coefficient, operating temperature range, and AEC-Q200 automotive certification. Both parts include moisture-resistant thick film construction and maintain RoHS3 compliance and MSL 1 rating.

Q: Why is the original RK73H1HTTC4700F marked as "Not For New Designs"?

A: This designation indicates that KOA Speer Electronics has superseded this part in their product line. The manufacturer recommends using RK73H1HTTCM4700F for new designs. However, the original part remains available for existing production and field support applications.

Q: Are there any packaging differences between these parts?

A: RK73H1HTTC4700F and AC0201FR-07470RL are both supplied in Tape & Reel (TR) packaging. RK73H1HTTCM4700F packaging is not specified in available documentation. Confirm packaging requirements with your supplier before ordering.

Q: Do all three parts meet automotive AEC-Q200 requirements?

A: Yes. All three parts carry AEC-Q200 certification and are suitable for automotive applications requiring this qualification.

Q: What is the significance of MSL 1 (Unlimited) rating?

A: MSL 1 indicates the lowest moisture sensitivity level. These parts have unlimited shelf life when stored in normal conditions and do not require special moisture-controlled storage or baking procedures prior to soldering.
