Substitute Part Grouping Explanation

Substitution eligibility for the RK73H1HTTC1200F is determined by strict equivalence across the following parameters:

Critical Matching Parameters:

• Resistance value: 120 Ohms
• 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 qualification: AEC-Q200
• Moisture resistance: Required
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity level: MSL 1

All identified substitute parts meet these criteria without exception. Substitution is based solely on electrical performance equivalence and mechanical compatibility within the specified package envelope.

Parameter Comparison

Engineering Selection Recommendations

RK73H1HTTCM1200F (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 Active product status. Selection of this part is appropriate for applications requiring continued supply from the original manufacturer. Compliance certifications (AEC-Q200, ROHS3, MSL 1) are fully maintained.

AC0201FR-07120RL (YAGEO): This part is a direct cross-reference from YAGEO and meets all electrical and mechanical equivalence criteria. It carries Active product status and maintains full compliance with AEC-Q200 automotive qualification and ROHS3 requirements. Selection of this part is appropriate when YAGEO supply chain access is preferred or when multi-source qualification is required.

Both substitute parts are electrically and mechanically interchangeable with the main part RK73H1HTTC1200F within the specified operating parameters.

Frequently Asked Questions (FAQ)

Q: Can RK73H1HTTCM1200F be used as a direct replacement for RK73H1HTTC1200F? A: Yes. Both parts are manufactured by KOA Speer Electronics, Inc., share identical electrical specifications (120 Ohms ±1%, 0.05W), and are packaged in the same 0201 format. The main difference is product status: RK73H1HTTCM1200F is Active, while RK73H1HTTC1200F is Not For New Designs.

Q: What is the difference between RK73H1HTTC1200F and AC0201FR-07120RL? A: The primary difference is manufacturer: RK73H1HTTC1200F is from KOA Speer Electronics, Inc., while AC0201FR-07120RL is from YAGEO. All electrical parameters (resistance, tolerance, power rating, temperature coefficient) and mechanical specifications (0201 package, dimensions, terminations) are identical. Both meet AEC-Q200 automotive qualification.

Q: Are all three parts suitable for automotive applications? A: Yes. All three parts carry AEC-Q200 qualification and are rated for the automotive temperature range of -55°C ~ 155°C with moisture-resistant thick film construction.

Q: What does "Not For New Designs" mean for RK73H1HTTC1200F? A: This designation indicates the part has been superseded. For new designs, KOA Speer Electronics, Inc. recommends using RK73H1HTTCM1200F instead. The main part remains available for legacy system support and existing inventory applications.

Q: Are there any packaging differences between these parts? A: RK73H1HTTC1200F is specified as Tape & Reel (TR) packaging. RK73H1HTTCM1200F packaging is not specified in the provided data. AC0201FR-07120RL is specified as Tape & Reel (TR) packaging. All three use the same 0201 (0603 Metric) package format.

Q: Do all parts meet RoHS compliance requirements? A: Yes. All three parts are ROHS3 Compliant and carry MSL 1 (Unlimited) moisture sensitivity rating, indicating no special moisture handling is required during storage or assembly.
