Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RK73H1HTTC2870F are qualified based on the following electrical and mechanical parameters:

Critical Matching Parameters:

• Resistance value: 287 Ohms (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)
• AEC-Q200 automotive qualification (exact match required)
• RoHS3 compliance (exact match required)
• MSL rating: 1 (Unlimited) (exact match required)

Substitutes are grouped into two categories:

Category 1: Manufacturer-Recommended Direct Equivalent Parts designated as manufacturer-recommended equivalents share identical electrical specifications and are produced by the original manufacturer as active-status replacements.

Category 2: Cross-Manufacturer Equivalents Parts from alternative manufacturers that meet all critical electrical and mechanical parameters, carry equivalent automotive and compliance certifications, and are currently in active production status.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: RK73H1HTTCM2870F

The RK73H1HTTCM2870F is the manufacturer-recommended equivalent from KOA Speer Electronics, Inc. This part carries active product status and maintains identical electrical specifications, package format, and automotive AEC-Q200 qualification. Selection of this part eliminates any cross-manufacturer compatibility considerations and ensures continuity with the original design intent. This part is the preferred choice for new procurement and system updates.

Secondary Substitute: AC0201FR-07287RL

The AC0201FR-07287RL from YAGEO meets all critical electrical and mechanical parameters specified for the RK73H1HTTC2870F. This part carries active product status, AEC-Q200 automotive qualification, ROHS3 compliance, and moisture-resistant construction. Cross-manufacturer substitution is electrically and mechanically valid based on parameter equivalence. Selection of this part is appropriate when supply chain considerations or cost factors necessitate cross-manufacturer sourcing.

Both substitute parts are currently in active production and carry equivalent compliance certifications. Selection between them should be based on supply availability, lead time requirements, and procurement preferences.

Frequently Asked Questions (FAQ)

Q: Can the RK73H1HTTCM2870F be used as a direct replacement for RK73H1HTTC2870F?

A: Yes. The RK73H1HTTCM2870F is the manufacturer-recommended equivalent. Both parts share identical resistance (287 Ohms), tolerance (±1%), power rating (0.05W), package format (0201), composition (thick film), temperature coefficient (±200ppm/°C), operating temperature range (-55°C ~ 155°C), AEC-Q200 qualification, and RoHS3 compliance. The primary difference is product status: RK73H1HTTCM2870F is active, while RK73H1HTTC2870F is not for new designs.

Q: Is the AC0201FR-07287RL from YAGEO compatible with designs specified for RK73H1HTTC2870F?

A: Yes. The AC0201FR-07287RL meets all critical electrical and mechanical parameters. Both parts are 287 Ohm ±1% thick film resistors rated at 0.05W in 0201 package format with ±200ppm/°C temperature coefficient, -55°C ~ 155°C operating range, 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 RK73H1HTTC2870F?

A: "Not For New Designs" indicates the part has been superseded in the manufacturer's product line. While existing inventory remains available, KOA Speer Electronics recommends using RK73H1HTTCM2870F for new applications. For legacy system maintenance and repair, RK73H1HTTC2870F remains functionally equivalent to its active-status substitute.

Q: Are there package format differences between these substitute parts?

A: All three parts use identical 0201 package format (0.60mm x 0.30mm metric, 0.024" L x 0.012" W). Physical dimensions, height when seated (0.010" maximum), and termination count (2) are identical across all parts. No PCB layout or assembly process modifications are required for substitution.

Q: Do all substitute parts carry AEC-Q200 automotive qualification?

A: Yes. RK73H1HTTC2870F, RK73H1HTTCM2870F, and AC0201FR-07287RL all carry AEC-Q200 automotive qualification. All parts are suitable for automotive applications requiring this certification level.

Q: What is the moisture sensitivity level (MSL) for these parts?

A: All three parts carry MSL 1 (Unlimited) rating. This indicates unlimited shelf life without moisture bake-out requirements. No special storage or handling procedures are necessary for moisture management.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. RK73H1HTTC2870F, RK73H1HTTCM2870F, and AC0201FR-07287RL are all ROHS3 compliant. All parts meet current environmental and hazardous substance restrictions.
