• Moisture sensitivity level: MSL 1

All identified substitute parts meet these parameters without exception. Substitution is valid across manufacturers when all electrical characteristics, package dimensions, and compliance certifications align with the main part specification.

Parameter Comparison

Engineering Selection Recommendations

RK73H1HTTCM1403F (KOA Speer Electronics, Inc.)

This part is a direct KOA manufacturer variant of the main part number. It maintains identical electrical specifications, package dimensions, and AEC-Q200 automotive qualification. The primary difference is the absence of moisture-resistant designation in the provided specification. Both parts are in active production status. Selection of this variant is appropriate when moisture resistance is not a circuit requirement.

AC0201FR-07140KL (YAGEO)

This YAGEO component provides full electrical and mechanical equivalence to the RK73H1HTTC1403F, including moisture-resistant thick film construction and AEC-Q200 automotive qualification. All critical parameters align without deviation. The AC0201FR-07140KL is in active production with significantly higher inventory availability (4900 units). This part is suitable for direct substitution in applications requiring automotive-grade, moisture-resistant 140 kOhms ±1% resistors in the 0201 package format.

Both substitute parts maintain compliance with ROHS3 and MSL 1 specifications. Selection between alternatives is determined by manufacturer preference, supply chain strategy, and inventory requirements rather than electrical or mechanical constraints.

Frequently Asked Questions (FAQ)

Q: Can the RK73H1HTTCM1403F be used as a direct replacement for the RK73H1HTTC1403F?

A: The RK73H1HTTCM1403F matches all electrical parameters and package specifications. The documented difference is the absence of moisture-resistant designation in the provided specification data. Substitution is valid when moisture resistance is not a design requirement. Verify circuit moisture exposure conditions before selection.

Q: What is the difference between the KOA and YAGEO variants?

A: Both the RK73H1HTTC1403F (KOA) and AC0201FR-07140KL (YAGEO) meet identical electrical specifications: 140 kOhms ±1%, 0.05W power rating, ±200ppm/°C temperature coefficient, -55°C to 155°C operating range, and AEC-Q200 automotive qualification. Both include moisture-resistant construction. The primary distinction is manufacturer origin and inventory availability.

Q: Are all substitute parts AEC-Q200 qualified?

A: Yes. All identified substitute parts carry AEC-Q200 automotive qualification, meeting the same reliability and qualification standards as the main part.

Q: Do all substitute parts have the same physical dimensions?

A: Yes. All parts conform to the 0201 (0603 Metric) package format with identical dimensions: 0.024" L x 0.012" W (0.60mm x 0.30mm) and maximum seated height of 0.010" (0.26mm).

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All identified substitute parts are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity level.

Q: Can these parts be used interchangeably in automotive applications?

A: Yes. All substitute parts carry AEC-Q200 automotive qualification and operate across the identical temperature range (-55°C ~ 155°C), enabling direct substitution in automotive circuit designs.

Q: What is the tolerance specification for all parts?

A: All parts maintain ±1% tolerance on the 140 kOhms resistance value, ensuring consistent performance across the substitution group.
