Substitute Part Grouping Explanation

Substitution eligibility for the RK73G1HTTC2002D is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

  • Resistance value: 20 kOhms
  • Tolerance: ±0.5%
  • Power rating: 0.05W (1/20W)
  • Temperature coefficient: ±50ppm/°C
  • Operating temperature range: -55°C to 155°C

Mechanical Parameters:

  • Package: 0201 (0603 Metric)
  • Number of terminations: 2
  • Physical dimensions: 0.024" L x 0.012" W (0.60mm x 0.30mm)
  • Maximum seated height: 0.010" (0.26mm)

Compliance & Quality Parameters:

  • Composition: Thick Film
  • Automotive qualification: AEC-Q200
  • RoHS status: ROHS3 Compliant

Frequently Asked Questions (FAQ)

Q: Can RK73G1HTTCM2002D replace RK73G1HTTC2002D in existing designs?

A: Yes. The RK73G1HTTCM2002D is electrically and mechanically identical to the RK73G1HTTC2002D. All electrical parameters (20 kOhms ±0.5%, 0.05W, ±50ppm/°C), package dimensions (0201/0603 Metric), and compliance certifications (AEC-Q200, ROHS3) are equivalent. Direct substitution is valid without circuit or layout modifications.

Q: Why is the main part marked "Not For New Designs"?

A: The RK73G1HTTC2002D designation indicates the part is in end-of-life phase. Manufacturers apply this status when transitioning products to successor models or discontinuing production. The RK73G1HTTCM2002D represents the active alternative for ongoing production and new design applications.

Q: Are there any packaging differences between these parts?

A: Both parts use identical 0201 (0603 Metric) packaging with 0.024" L x 0.012" W (0.60mm x 0.30mm) dimensions and 0.010" (0.26mm) maximum seated height. Tape & Reel (TR) packaging is standard for both. No PCB footprint or assembly process changes are required.

Q: Do both parts meet automotive qualification standards?

A: Yes. Both the RK73G1HTTC2002D and RK73G1HTTCM2002D carry AEC-Q200 qualification, confirming suitability for automotive applications across the -55°C to 155°C operating temperature range.

Q: What is the inventory status for the substitute part?

A: The RK73G1HTTCM2002D has 751 pieces in stock as new original inventory. The RK73G1HTTC2002D has 974 pieces available. Inventory levels should be verified directly with the supplier for current availability.

Q: Are there any tolerance or temperature coefficient differences?

A: No. Both parts maintain ±0.5% tolerance and ±50ppm/°C temperature coefficient. Electrical performance characteristics are identical across all operating conditions within the -55°C to 155°C range.
