Key Parameters

Substitute Part Grouping Explanation

Substitution of the RK73H1HTTC6041F is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 6.04 kOhms
• Tolerance: ±1%
• Power rating: 0.05W (1/20W)
• Package: 0201 (0603 Metric)
• Composition: Thick Film
• Temperature coefficient: ±200ppm/°C
• RoHS compliance: ROHS3 Compliant
• MSL rating: 1 (Unlimited)

Acceptable Variation Parameters:

• Manufacturer identity (different suppliers)
• Product status (Active vs. Not For New Designs)
• Operating temperature range (provided minimum -55°C is maintained)
• Automotive certification presence (AEC-Q200 preferred but not mandatory for all substitutes)

The substitute parts identified below meet all mandatory parameters and are therefore electrically and mechanically interchangeable with the RK73H1HTTC6041F in standard PCB assembly processes.

Engineering Selection Recommendations

Primary Recommendation: RK73H1HTTCM6041F (KOA Speer Electronics)

The RK73H1HTTCM6041F is the manufacturer-recommended successor to the RK73H1HTTC6041F. Both parts are produced by KOA Speer Electronics and share identical electrical and mechanical specifications. The primary distinction is product status: RK73H1HTTCM6041F is Active, while the original part is marked Not For New Designs. This part maintains full AEC-Q200 automotive qualification and moisture-resistant construction. Selection of this part ensures design continuity with minimal supply chain transition risk.

Secondary Recommendation: AC0201FR-076K04L (YAGEO)

The AC0201FR-076K04L from YAGEO is a direct electrical and mechanical equivalent with Active product status. It maintains all critical parameters including AEC-Q200 automotive qualification, moisture resistance, and identical package dimensions. YAGEO is an established supplier with broad market availability. This part is suitable for applications requiring multi-source qualification.

Tertiary Recommendation: ERJ-1GNF6041C (Panasonic Electronic Components)

The ERJ-1GNF6041C from Panasonic Electronic Components meets all mandatory electrical and mechanical parameters. The operating temperature range extends to -55°C ~ 125°C, which is acceptable for most applications but does not reach the 155°C maximum of the original part. Automotive certification details are not specified in the provided data. This part offers the highest inventory availability (91,664 Pcs) and is suitable for applications not requiring the extended upper temperature range or explicit AEC-Q200 marking.

Selection Criteria:

• For automotive applications requiring AEC-Q200 certification and extended temperature range (-55°C to 155°C): Select RK73H1HTTCM6041F or AC0201FR-076K04L
• For general-purpose applications with standard automotive temperature range (-55°C to 125°C): ERJ-1GNF6041C is acceptable
• For supply chain redundancy: Qualify multiple suppliers from the three options above

Frequently Asked Questions (FAQ)

Q1: Can I use ERJ-1GNF6041C as a direct replacement for RK73H1HTTC6041F in automotive applications?

A: The ERJ-1GNF6041C is electrically and mechanically equivalent for resistance, tolerance, power rating, and package specifications. However, the operating temperature range differs: ERJ-1GNF6041C operates to 125°C maximum, while RK73H1HTTC6041F operates to 155°C. If your application requires operation above 125°C, use RK73H1HTTCM6041F or AC0201FR-076K04L instead. Additionally, automotive certification details for the Panasonic part are not specified; verify AEC-Q200 compliance with the supplier if required.

Q2: What is the difference between RK73H1HTTC6041F and RK73H1HTTCM6041F?

A: Both parts are manufactured by KOA Speer Electronics and are electrically and mechanically identical. The primary difference is product status: RK73H1HTTC6041F is marked "Not For New Designs," indicating it has been superseded. RK73H1HTTCM6041F is the Active replacement with identical specifications. For new designs or ongoing production, RK73H1HTTCM6041F is the recommended choice.

Q3: Are all substitute parts ROHS3 compliant and MSL 1 rated?

A: Yes. All substitute parts listed (RK73H1HTTCM6041F, AC0201FR-076K04L, and ERJ-1GNF6041C) are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity ratings, matching the original RK73H1HTTC6041F specification.

Q4: Can I mix suppliers in the same PCB assembly?

A: Yes. All substitute parts meet identical electrical and mechanical specifications and are suitable for mixed-supplier assembly. However, verify with your quality and procurement departments that multi-source qualification is approved for your application, particularly in automotive or regulated environments.

Q5: What does "Not For New Designs" mean for the RK73H1HTTC6041F?

A: "Not For New Designs" indicates that the manufacturer has superseded this part number and recommends using the newer equivalent (RK73H1HTTCM6041F) for new product development. Existing inventory of RK73H1HTTC6041F may still be available for legacy system support or maintenance, but new designs should transition to the Active replacement part.

Q6: Are there any package or footprint differences between these parts?

A: No. All substitute parts use the 0201 (0603 Metric) package with identical dimensions: 0.024" L × 0.012" W (0.60mm × 0.30mm) and maximum seated height of 0.010" (0.26mm). PCB footprints and assembly processes are interchangeable.

Q7: Which substitute part has the best inventory availability?

A: ERJ-1GNF6041C (Panasonic) has the highest inventory availability at 91,664 Pcs. RK73H1HTTC6041F (original) has 62,586 Pcs, AC0201FR-076K04L (YAGEO) has 803 Pcs, and RK73H1HTTCM6041F (KOA replacement) has 1,016 Pcs. Inventory levels are subject to change; verify current availability with your supplier.
