Equivalent & Substitute Parts for RK73H1HTTC7153F

Part Overview

The RK73H1HTTC7153F is a 715 kOhm ±1% thick film chip resistor manufactured by KOA Speer Electronics, Inc., rated at 0.05W (1/20W) in a 0201 package (0.60mm x 0.30mm metric). This component is designed for automotive applications with AEC-Q200 qualification and moisture-resistant construction. The part is currently in active production status with 1132 units in stock.

Substitute parts are identified when equivalent electrical performance, mechanical compatibility, and regulatory compliance can be maintained across alternative manufacturers. Substitution becomes necessary due to supply chain constraints, lead time requirements, or design flexibility in multi-source component strategies.

Substitute Part Grouping Explanation

Substitution logic for the RK73H1HTTC7153F is based on strict electrical and mechanical parameter matching:

Primary Substitution Criteria:

• Resistance value: 715 kOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 0.05W minimum (equal or higher acceptable)
• Package: 0201 (0603 Metric) (exact match required for PCB assembly)
• Temperature coefficient: ±200ppm/°C or better
• Operating temperature range: -55°C to 155°C minimum
• Automotive qualification: AEC-Q200 (required)
• RoHS compliance: ROHS3 Compliant (required)

Identified Substitute Categories:

1. Manufacturer-Recommended Substitute (KOA Speer Electronics): RK73H1HTTCM7153F — Same manufacturer, same series, identical electrical specifications with alternative moisture-resistant formulation designation.

2. Direct Cross-Reference Substitute (YAGEO): AC0201FR-07715KL — Alternative manufacturer with equivalent electrical performance, automotive qualification, and moisture-resistant thick film construction.

All identified substitutes maintain identical key parameters across resistance, tolerance, power rating, package dimensions, temperature range, and automotive compliance ratings.

Parameter Comparison

Engineering Selection Recommendations

RK73H1HTTCM7153F (KOA Speer Electronics, Inc.)

This part is the manufacturer-recommended substitute within the KOA Speer RK73H series. It maintains identical electrical specifications and automotive AEC-Q200 qualification. Selection of this variant is appropriate when maintaining single-manufacturer sourcing is a design requirement or when supply from the original part number is constrained. Current inventory: 721 units.

AC0201FR-07715KL (YAGEO)

This part provides cross-manufacturer substitution with equivalent electrical performance and automotive compliance. YAGEO AC series thick film resistors meet all specified parameters including AEC-Q200 rating, ROHS3 compliance, and moisture-resistant construction. Selection of this part is appropriate for multi-source component strategies or when YAGEO supply chain access is preferred. Current inventory: 959 units.

All three parts are in active production status with ROHS3 compliance and AEC-Q200 automotive qualification. Selection between them is based on supply availability, procurement strategy, and manufacturing partnership preferences rather than electrical or mechanical performance differences.

Frequently Asked Questions (FAQ)

Q: Can RK73H1HTTCM7153F be used as a direct replacement for RK73H1HTTC7153F?

A: Yes. Both parts are manufactured by KOA Speer Electronics within the RK73H series and share identical electrical specifications (715 kOhms ±1%, 0.05W), package dimensions (0201), temperature range (-55°C to 155°C), and automotive AEC-Q200 qualification. The designation difference reflects internal KOA product line variations but does not affect functional compatibility.

Q: Can AC0201FR-07715KL from YAGEO be used in place of the KOA part?

A: Yes. AC0201FR-07715KL meets all critical substitution parameters: 715 kOhms ±1% resistance, 0.05W power rating, 0201 package, ±200ppm/°C temperature coefficient, -55°C to 155°C operating range, AEC-Q200 automotive rating, and ROHS3 compliance. Cross-manufacturer substitution is electrically and mechanically valid.

Q: Are there any differences in moisture resistance between these parts?

A: RK73H1HTTC7153F and AC0201FR-07715KL are both specified as moisture-resistant thick film resistors with MSL 1 (Unlimited) rating. RK73H1HTTCM7153F does not explicitly list moisture-resistant in its description, though it maintains the same MSL 1 rating. All three parts are suitable for applications requiring moisture protection.

Q: What is the significance of the 0201 package specification?

A: The 0201 package (0.60mm x 0.30mm metric, 0.024" x 0.012" imperial) is a miniature surface-mount form factor. All three substitute parts use identical package dimensions and termination configuration (2 terminations), ensuring direct PCB footprint compatibility without layout modifications.

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

A: Yes. RK73H1HTTC7153F, RK73H1HTTCM7153F, and AC0201FR-07715KL all carry AEC-Q200 automotive qualification. This certification is maintained across all identified substitutes and is a non-negotiable parameter for automotive circuit applications.

Q: What is the temperature coefficient specification and why does it matter?

A: All three parts specify ±200ppm/°C temperature coefficient. This parameter defines the resistance value change per degree Celsius across the operating temperature range. Matching or superior temperature coefficients ensure consistent circuit performance across the -55°C to 155°C automotive operating range.

Q: Are there inventory considerations when selecting between these parts?

A: Current inventory levels are: RK73H1HTTC7153F (1132 units), RK73H1HTTCM7153F (721 units), and AC0201FR-07715KL (959 units). Inventory status may influence procurement decisions for high-volume applications, though all parts are in active production with ongoing availability.
