Key Parameters

Substitute Part Grouping Explanation

Substitution of the RK73G1HTTC3302F is determined by strict equivalence across the following critical parameters:

Electrical Parameters: Resistance value (33 kOhms), tolerance (±1%), and power rating (0.05W) must be identical. Temperature coefficient (±50ppm/°C) and operating temperature range (-55°C ~ 155°C) establish thermal performance boundaries.

Mechanical Parameters: Package designation (0201 / 0603 Metric) and physical dimensions (0.024" L × 0.012" W, height 0.010" max) ensure PCB compatibility and assembly process alignment.

Compliance Parameters: AEC-Q200 automotive qualification, ROHS3 compliance, and MSL 1 rating are mandatory for applications requiring automotive-grade reliability and environmental standards adherence.

Composition: Thick film construction must be maintained to preserve electrical characteristics and thermal behavior.

Only parts meeting all these criteria across electrical, mechanical, and compliance domains qualify as true substitutes.

Parameter Comparison

Engineering Selection Recommendations

The RK73G1HTTCM3302F serves as the direct substitute for RK73G1HTTC3302F. Both components are manufactured by KOA Speer Electronics within the RK73G series and maintain identical electrical, mechanical, and thermal specifications. The primary distinction is product lifecycle status: the original part is designated "Not For New Designs," while the substitute maintains "Active" status within the manufacturer's current portfolio.

For applications currently using RK73G1HTTC3302F, transition to RK73G1HTTCM3302F ensures continued supply availability and manufacturer support. Both parts satisfy AEC-Q200 automotive qualification requirements and ROHS3 environmental compliance, making them suitable for automotive-grade circuit implementations requiring 33 kOhms resistance in 0201 package form factor.

The substitute part carries higher inventory availability (1044 pieces versus 775 pieces), supporting production continuity and reducing procurement lead time risk.

Frequently Asked Questions (FAQ)

Q: Can RK73G1HTTCM3302F be used as a direct replacement for RK73G1HTTC3302F in existing designs?

A: Yes. Both parts are electrically and mechanically identical across all specified parameters: 33 kOhms ±1% resistance, 0.05W power rating, 0201 package, ±50ppm/°C temperature coefficient, and -55°C ~ 155°C operating range. AEC-Q200 and ROHS3 compliance are maintained. No circuit redesign or PCB layout modification is required.

Q: Why is RK73G1HTTC3302F marked "Not For New Designs"?

A: This designation indicates the part has been superseded in the manufacturer's active product line. KOA Speer Electronics recommends RK73G1HTTCM3302F for new design implementations. Existing applications may continue using either part interchangeably based on supply availability.

Q: Are there any packaging differences between these parts?

A: Both parts use identical 0201 (0603 Metric) package specifications with matching physical dimensions (0.024" L × 0.012" W, 0.010" max height). Tape & Reel packaging format is standard for both. No assembly process modifications are necessary.

Q: What compliance certifications apply to both parts?

A: Both RK73G1HTTC3302F and RK73G1HTTCM3302F carry AEC-Q200 automotive qualification, ROHS3 compliance, MSL 1 (Unlimited) moisture sensitivity rating, and REACH Unaffected status. These certifications ensure suitability for automotive and industrial applications with stringent environmental and reliability requirements.

Q: Can these 0201 resistors be used in high-temperature automotive applications?

A: Yes. Both parts operate across -55°C ~ 155°C temperature range with ±50ppm/°C temperature coefficient, meeting automotive thermal specifications. AEC-Q200 qualification confirms reliability under automotive environmental stress conditions.
