Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RK73H1HTTC2053F is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 205 kOhms
• Tolerance: ±1%
• Power rating: 0.05W (1/20W)
• Package format: 0201 (0603 Metric)
• Composition: Thick Film
• Temperature coefficient: ±200ppm/°C
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity level: 1 (Unlimited)

Acceptable Variation Parameters:

• Manufacturer identity (KOA Speer Electronics, YAGEO, Panasonic)
• Operating temperature range (provided minimum -55°C is maintained)
• Automotive rating presence (AEC-Q200 certification)
• Moisture resistance feature availability

All substitute parts listed maintain identical electrical specifications and package dimensions, ensuring direct functional replacement without circuit redesign or board layout modification.

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: RK73H1HTTCM2053F

The RK73H1HTTCM2053F is the manufacturer-recommended successor from KOA Speer Electronics. This part maintains identical electrical and mechanical specifications to the main part while carrying Active product status. Selection of this part ensures continuity with the original manufacturer's design intent and provides access to current production inventory and supply chain support.

Secondary Recommendation: AC0201FR-07205KL

The AC0201FR-07205KL from YAGEO provides full electrical and mechanical equivalence with the addition of explicit moisture-resistant construction. This part carries Active status and AEC-Q200 automotive qualification, making it suitable for applications requiring automotive-grade reliability. YAGEO's established supply chain and high inventory levels support consistent availability.

Tertiary Recommendation: ERJ-1GNF2053C

The ERJ-1GNF2053C from Panasonic Electronic Components meets all mandatory electrical specifications and maintains the 0201 package format. This part carries Active status and demonstrates the highest inventory availability among all substitutes. The operating temperature range extends to -55°C minimum, though the upper limit is 125°C compared to 155°C for the main part. Selection of this part is appropriate for applications where the maximum operating temperature does not exceed 125°C.

Compliance Considerations:

All substitute parts maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating, ensuring compatibility with standard manufacturing and storage protocols. Parts carrying explicit AEC-Q200 certification (RK73H1HTTCM2053F and AC0201FR-07205KL) are preferred for automotive and mission-critical applications.

Frequently Asked Questions (FAQ)

Q: Can RK73H1HTTCM2053F be used as a direct replacement for RK73H1HTTC2053F?

A: Yes. The RK73H1HTTCM2053F is the manufacturer-recommended equivalent from KOA Speer Electronics. Both parts share identical resistance (205 kOhms), tolerance (±1%), power rating (0.05W), package format (0201), composition (thick film), temperature coefficient (±200ppm/°C), and operating temperature range (-55°C ~ 155°C). The primary difference is product status: the main part is "Not For New Designs" while the substitute is "Active."

Q: What is the difference between AC0201FR-07205KL and RK73H1HTTC2053F?

A: Both parts are electrically and mechanically identical with respect to resistance, tolerance, power rating, package, and temperature specifications. The AC0201FR-07205KL is manufactured by YAGEO rather than KOA Speer Electronics and explicitly specifies moisture-resistant construction. Both carry AEC-Q200 automotive qualification and ROHS3 compliance.

Q: Is ERJ-1GNF2053C suitable for all applications using RK73H1HTTC2053F?

A: The ERJ-1GNF2053C is suitable for applications where the maximum operating temperature does not exceed 125°C. The main part and other substitutes support operation to 155°C. For applications requiring the full -55°C to 155°C temperature range, ERJ-1GNF2053C is not appropriate. For applications with maximum operating temperatures at or below 125°C, ERJ-1GNF2053C provides full functional equivalence.

Q: Are all substitute parts available in Tape & Reel packaging?

A: AC0201FR-07205KL and ERJ-1GNF2053C are explicitly specified as Tape & Reel (TR) packaging. RK73H1HTTCM2053F packaging format is not specified in available documentation. Confirm packaging requirements with the supplier before procurement.

Q: Do all substitute parts carry automotive qualification?

A: RK73H1HTTCM2053F and AC0201FR-07205KL carry explicit AEC-Q200 automotive qualification. ERJ-1GNF2053C does not specify automotive rating in available documentation. For applications requiring automotive-grade components, select from RK73H1HTTCM2053F or AC0201FR-07205KL.

Q: What is the significance of "Moisture Resistant" specification?

A: Moisture-resistant construction provides enhanced protection against moisture ingress and corrosion in humid or high-moisture environments. RK73H1HTTC2053F and AC0201FR-07205KL explicitly specify moisture-resistant features. All parts maintain MSL 1 (Unlimited) rating, indicating minimal moisture sensitivity during standard handling and storage.

Q: Can these parts be used interchangeably on the same printed circuit board?

A: Yes. All substitute parts maintain identical 0201 (0603 metric) package dimensions: 0.024" L × 0.012" W (0.60mm × 0.30mm) with maximum seated height of 0.010" (0.26mm). No board layout or footprint modification is required for substitution.
