Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RK73H1HTTC3832F is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 38.3 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 rating: 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 grouped into two categories: manufacturer-recommended alternatives from KOA Speer Electronics and direct cross-reference parts from alternative manufacturers.

Parameter Comparison

Engineering Selection Recommendations

RK73H1HTTCM3832F (KOA Speer Electronics, Inc.)

This part is the manufacturer-recommended substitute from KOA Speer Electronics. It maintains identical electrical and mechanical specifications to the main part while carrying an "Active" product status. This option is preferred for applications requiring continuity within the KOA Speer product ecosystem. All compliance certifications (ROHS3, AEC-Q200, MSL 1) are maintained.

AC0201FR-0738K3L (YAGEO)

This part provides cross-manufacturer equivalence with full parameter matching. YAGEO's AC series thick film resistor meets all electrical specifications, package requirements, and automotive certifications. This option is suitable for applications where multi-source component qualification is required or where YAGEO supply chain availability is preferred. All compliance certifications are equivalent.

Both substitute parts are suitable for direct replacement in applications currently using RK73H1HTTC3832F, provided that component qualification procedures have been completed for the target application.

Frequently Asked Questions (FAQ)

Q: Can RK73H1HTTCM3832F be used as a direct replacement for RK73H1HTTC3832F?

A: Yes. RK73H1HTTCM3832F is the manufacturer-recommended substitute from KOA Speer Electronics. It matches all electrical parameters (38.3 kOhms ±1%, 0.05W), mechanical specifications (0201 package), and compliance ratings (AEC-Q200, ROHS3, MSL 1). The primary difference is product status: RK73H1HTTCM3832F is Active, while the original is Not For New Designs.

Q: What is the difference between RK73H1HTTC3832F and RK73H1HTTCM3832F?

A: Both parts are manufactured by KOA Speer Electronics with identical electrical and mechanical specifications. The suffix difference (C vs. CM) reflects internal product line designation. RK73H1HTTCM3832F represents the current active product line continuation.

Q: Can AC0201FR-0738K3L from YAGEO replace the KOA part?

A: Yes, provided component qualification has been completed. AC0201FR-0738K3L matches all critical parameters: 38.3 kOhms ±1%, 0.05W, 0201 package, ±200ppm/°C temperature coefficient, -55°C to 155°C operating range, AEC-Q200 automotive rating, and ROHS3 compliance. Cross-manufacturer substitution requires validation per your quality and design procedures.

Q: Are all substitute parts available in the same packaging format?

A: Yes. All listed substitutes are supplied in 0201 (0603 Metric) package format with identical physical dimensions: 0.024" L x 0.012" W (0.60mm x 0.30mm) and maximum seated height of 0.010" (0.26mm).

Q: Do the substitute parts maintain the same moisture resistance properties?

A: RK73H1HTTCM3832F and AC0201FR-0738K3L both carry MSL 1 (Unlimited) rating. AC0201FR-0738K3L explicitly specifies moisture-resistant construction. All parts are suitable for applications requiring moisture protection.

Q: What compliance certifications apply to all substitute parts?

A: All parts listed are ROHS3 Compliant, AEC-Q200 rated for automotive applications, and carry MSL 1 moisture sensitivity level. REACH status is Unaffected for all parts. ECCN classification is EAR99 for all parts.
