Substitute Part Grouping Explanation

Substitute parts for the RK73G1HTTC2002F are identified based on strict electrical and mechanical parameter matching. The substitution logic is based on the following criteria:

Critical Parameters (Must Match Exactly):

• Resistance value: 20 kOhms
• Tolerance: ±1%
• Power rating: 0.05W (1/20W)
• Package format: 0201 (0.60mm x 0.30mm)
• Automotive qualification: AEC-Q200

Important Parameters (Must Match or Exceed):

• Composition: Thick Film
• Temperature coefficient: ±50ppm/°C
• Operating temperature range: -55°C ~ 155°C
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity: MSL 1

Substitution Basis: Parts are considered equivalent when they maintain identical electrical specifications (resistance, tolerance, power), identical physical package dimensions, and equivalent or superior environmental ratings. The RK73G series designation indicates parts within the same product family. Substitutes must retain AEC-Q200 automotive qualification to ensure reliability in automotive applications.

Parameter Comparison

Engineering Selection Recommendations

RK73G1HTTCM2002F is the direct equivalent substitute for RK73G1HTTC2002F. Both parts are manufactured by KOA Speer Electronics, Inc. within the RK73G series and maintain identical electrical and mechanical specifications across all critical parameters.

Key Selection Factors:

1. Product Status Transition: The main part RK73G1HTTC2002F is classified as "Not For New Designs," while the substitute RK73G1HTTCM2002F maintains "Active" status. This indicates the substitute represents the current production alternative within the same product family.

3. Electrical Performance: Resistance value, tolerance, power rating, temperature coefficient, and operating temperature range are identical. Direct functional substitution is supported.

4. Physical Compatibility: Both parts use the 0201 package format with identical dimensions (0.60mm x 0.30mm). PCB footprints and assembly processes require no modification.

5. Supply Continuity: The substitute part maintains active inventory status, supporting long-term supply chain reliability for ongoing production requirements.

Frequently Asked Questions (FAQ)

Q: Can RK73G1HTTCM2002F be used as a direct replacement for RK73G1HTTC2002F in existing designs?

A: Yes. Both parts are electrically and mechanically identical. All critical parameters—resistance value, tolerance, power rating, package format, and automotive qualification—match exactly. No circuit modifications or PCB redesign are required.

Q: What is the difference between these two part numbers?

A: The primary difference is product status. RK73G1HTTC2002F is classified as "Not For New Designs," indicating it has been superseded. RK73G1HTTCM2002F is the active equivalent that replaces it in the manufacturer's current product line. The "M" designation in the part number indicates the active variant.

Q: Are there any thermal or reliability differences between these parts?

A: No. Both parts share identical thermal specifications (temperature coefficient ±50ppm/°C, operating range -55°C ~ 155°C) and identical AEC-Q200 automotive qualification. Reliability performance is equivalent.

Q: Can these parts be mixed in the same production batch?

A: Yes. Since all electrical, mechanical, and compliance parameters are identical, both parts can be used interchangeably within the same assembly without affecting circuit performance or reliability.

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

A: The 0201 package (0.60mm x 0.30mm) is a miniature surface-mount format. Both parts use this identical package, ensuring compatibility with existing PCB layouts, pick-and-place equipment, and reflow soldering processes.

Q: Are both parts RoHS compliant?

A: Yes. Both RK73G1HTTC2002F and RK73G1HTTCM2002F are ROHS3 compliant, meeting environmental and regulatory requirements for automotive and industrial applications.

Q: What does MSL 1 (Unlimited) mean for storage?

A: MSL 1 indicates the lowest moisture sensitivity level. These parts have unlimited shelf life under normal storage conditions and do not require special moisture-controlled storage or baking procedures prior to assembly.
