Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RK73H1HTTC4871F are qualified based on strict electrical and mechanical parameter matching:

Qualifying Parameters for Substitution:

• Resistance value: 4.87 kOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 0.05W / 1/20W (exact match required)
• Package format: 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 compliance: AEC-Q200 (exact match required)
• RoHS compliance: ROHS3 Compliant (exact match required)
• Moisture sensitivity: MSL 1 (exact match required)

All identified substitutes meet these criteria and are therefore electrically and mechanically interchangeable with the RK73H1HTTC4871F in applications requiring these specifications.

Engineering Selection Recommendations

RK73H1HTTCM4871F (KOA Speer Electronics, Inc. - Active Status)

This part is the manufacturer-recommended substitute from KOA Speer Electronics, Inc. It maintains active product status and carries identical electrical specifications to the RK73H1HTTC4871F. The primary distinction is product lifecycle status; RK73H1HTTCM4871F is actively supported for new and ongoing production. This part is suitable for all applications currently using RK73H1HTTC4871F and is recommended for new designs requiring this resistance value and specification set.

AC0201FR-074K87L (YAGEO - Active Status)

This part is a direct cross-reference from YAGEO and maintains active product status. It meets all electrical and mechanical parameters required for substitution, including AEC-Q200 automotive rating, moisture resistance, and ROHS3 compliance. The AC0201FR-074K87L is suitable for applications requiring interchangeability with RK73H1HTTC4871F and provides an alternative sourcing option from a different manufacturer.

Both substitute parts are qualified for direct replacement in automotive and industrial applications where the RK73H1HTTC4871F was originally specified.

Frequently Asked Questions (FAQ)

Q: Can RK73H1HTTCM4871F be used as a direct replacement for RK73H1HTTC4871F?

A: Yes. Both parts share identical electrical specifications (4.87 kOhms ±1%, 0.05W, ±200ppm/°C, -55°C to 155°C), package format (0201), composition (thick film), and automotive compliance (AEC-Q200). The primary difference is product status; RK73H1HTTCM4871F is actively manufactured while RK73H1HTTC4871F is not for new designs.

Q: Is AC0201FR-074K87L compatible with RK73H1HTTC4871F in automotive applications?

A: Yes. AC0201FR-074K87L meets all required specifications for automotive use, including AEC-Q200 rating, identical resistance and tolerance values, matching power rating, and equivalent temperature operating range. It is suitable for direct substitution in automotive circuits.

Q: What are the critical parameters that must match for substitution?

A: The following parameters must match exactly: resistance value (4.87 kOhms), tolerance (±1%), power rating (0.05W), package format (0201), composition (thick film), temperature coefficient (±200ppm/°C), operating temperature range (-55°C to 155°C), and AEC-Q200 automotive rating. All substitute parts listed meet these requirements.

Q: Are there packaging differences between the substitute parts?

A: All three parts use identical 0201 (0603 Metric) package format with matching physical dimensions (0.024" L x 0.012" W / 0.60mm x 0.30mm) and maximum seated height (0.010" / 0.26mm). Packaging is fully compatible across all substitutes.

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

A: MSL 1 indicates the component has unlimited shelf life and requires no special moisture control during storage or handling. All listed parts carry this rating, ensuring equivalent moisture sensitivity characteristics.

Q: Why is RK73H1HTTC4871F marked "Not For New Designs"?

A: This designation indicates the part has reached end-of-life status in the manufacturer's product portfolio. RK73H1HTTCM4871F represents the active replacement from the same manufacturer, while AC0201FR-074K87L provides an alternative from a different manufacturer. Both are suitable for new design implementations.
