Substitute Part Grouping Explanation

Substitution eligibility for the RK73H1HTTC2004F is determined by strict equivalence across the following critical parameters:

Electrical Parameters: Resistance value (2 MOhms), tolerance (±1%), power rating (0.05W), and temperature coefficient (±200ppm/°C) must match exactly.

Package Parameters: Physical package designation (0201 / 0603 Metric), footprint dimensions (0.024" L x 0.012" W), and termination count (2) must be identical.

Environmental & Compliance Parameters: Operating temperature range (-55°C to 155°C), AEC-Q200 automotive qualification, moisture sensitivity level (MSL 1), RoHS3 compliance, and REACH status must align.

Composition: Thick film construction is required for functional equivalence.

Substitute parts must satisfy all parameters simultaneously. Partial parameter matching does not establish substitution eligibility.

Frequently Asked Questions (FAQ)

Q: Can RK73H1HTTCM2004F be used as a direct replacement for RK73H1HTTC2004F in existing designs?

A: Yes. Both components are electrically and mechanically identical across all specified parameters: 2 MOhms resistance, ±1% tolerance, 0.05W power rating, 0201 package, ±200ppm/°C temperature coefficient, and -55°C to 155°C operating range. PCB layout and circuit design require no modification.

Q: What is the significance of the "Not For New Designs" status on RK73H1HTTC2004F?

A: This designation indicates the component is in end-of-life phase. Existing applications may continue using available inventory, but new design implementations should transition to RK73H1HTTCM2004F, which maintains active production status and manufacturer support.

Q: Are there any differences in moisture handling or storage between these two parts?

A: No. Both components carry MSL 1 (Unlimited) moisture sensitivity level, indicating no special moisture control requirements during storage, handling, or assembly.

Q: Do both parts meet automotive qualification standards?

A: Yes. Both RK73H1HTTC2004F and RK73H1HTTCM2004F are AEC-Q200 qualified, meeting automotive industry reliability and performance standards.

Q: Are there packaging differences between the main part and substitute?

A: No. Both components use identical 0201 (0603 Metric) package format with matching footprint dimensions (0.024" L x 0.012" W) and maximum seated height (0.010").
