Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RK73H1HTTC2612F is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 26.1 kOhms
• Tolerance: ±1%
• Power rating: 0.05W (1/20W)
• Package format: 0201 (0603 Metric)
• Composition: Thick Film
• Temperature coefficient: ±200ppm/°C
• Operating temperature range: -55°C ~ 155°C
• Automotive compliance: AEC-Q200
• Moisture resistance: Required
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity level: MSL 1

All identified substitute parts meet these parameters without exception. Substitutes are classified into two categories: manufacturer-recommended alternatives and direct cross-reference equivalents.

Engineering Selection Recommendations

RK73H1HTTCM2612F (KOA Speer Electronics, Inc.)

This part is the manufacturer-recommended successor to the RK73H1HTTC2612F. Both components are from the same manufacturer and share identical electrical and mechanical specifications. The RK73H1HTTCM2612F carries an "Active" product status, indicating ongoing manufacturing and supply availability. This part is the preferred selection for new production runs and design revisions requiring KOA Speer sourcing.

AC0201FR-0726K1L (YAGEO)

This part provides direct cross-reference equivalence with identical electrical parameters, mechanical dimensions, and automotive compliance ratings. Manufactured by YAGEO, the AC0201FR-0726K1L is classified as "Active" and offers an alternative supply source. This component is suitable for applications where multi-source qualification is required or when KOA Speer supply is constrained. Both parts meet AEC-Q200 automotive standards and ROHS3 compliance requirements.

Selection between these substitutes should be based on supply chain requirements, qualification status within your organization, and sourcing agreements with component distributors.

Frequently Asked Questions (FAQ)

Q: Can RK73H1HTTCM2612F directly replace RK73H1HTTC2612F in existing designs?

A: Yes. Both components share identical electrical specifications (26.1 kOhms ±1%, 0.05W), mechanical dimensions (0201 package), temperature characteristics (±200ppm/°C, -55°C ~ 155°C), and automotive certifications (AEC-Q200). The RK73H1HTTCM2612F is the active production equivalent from the same manufacturer.

Q: Is AC0201FR-0726K1L compatible with designs specified for RK73H1HTTC2612F?

A: Yes. The AC0201FR-0726K1L meets all critical electrical and mechanical parameters: 26.1 kOhms ±1%, 0.05W power rating, 0201 package format, ±200ppm/°C temperature coefficient, -55°C ~ 155°C operating range, AEC-Q200 automotive rating, and ROHS3 compliance. This part is suitable for direct substitution in automotive applications.

Q: What is the significance of "Not For New Designs" status on RK73H1HTTC2612F?

A: This designation indicates the part has been superseded by the manufacturer and is no longer recommended for new product development. Existing inventory remains available for legacy design support. For new designs, RK73H1HTTCM2612F or AC0201FR-0726K1L should be specified.

Q: Are there packaging differences between the substitute parts?

A: RK73H1HTTC2612F and AC0201FR-0726K1L are both supplied in Tape & Reel (TR) format. RK73H1HTTCM2612F packaging type is not specified in available documentation. Confirm packaging requirements with your distributor or manufacturer before procurement.

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

A: Yes. RK73H1HTTCM2612F and AC0201FR-0726K1L both carry AEC-Q200 ratings and are qualified for automotive applications. Moisture sensitivity level is MSL 1 (Unlimited) for all parts, indicating no special storage or handling requirements.

Q: What is the difference between RK73H series and AC series resistors?

A: Both series are thick film chip resistors with identical electrical and mechanical specifications for this 26.1 kOhms value. The primary difference is manufacturer: KOA Speer Electronics (RK73H) versus YAGEO (AC). Selection between manufacturers depends on supply chain strategy and qualification requirements.
