Key Parameters

Substitute Part Grouping Explanation

Substitution of the RK73G1HTTC7500F is determined by strict equivalence across the following critical parameters:

Electrical Parameters: Resistance value (750 Ohms), 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 format (0201 / 0603 Metric), physical dimensions (0.024" L x 0.012" W / 0.60mm x 0.30mm), and number of terminations (2) must match exactly to ensure PCB footprint compatibility.

Compliance Parameters: Automotive AEC-Q200 qualification, RoHS3 compliance, and MSL 1 rating are mandatory for equivalent substitution in automotive and regulated applications.

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

Parts meeting all these criteria are classified as direct equivalents and may be substituted without circuit redesign or PCB layout modification.

Parameter Comparison

Engineering Selection Recommendations

The RK73G1HTTCM7500F is the direct equivalent substitute for the RK73G1HTTC7500F. All electrical, mechanical, and thermal parameters are identical. The substitute part carries Active product status, whereas the main part is designated Not For New Designs. This status difference reflects the manufacturer's product lifecycle management and indicates that RK73G1HTTCM7500F is the current production alternative.

Both parts maintain identical AEC-Q200 automotive qualification, ROHS3 compliance, and MSL 1 rating. No circuit redesign, PCB layout modification, or thermal analysis revision is required when substituting RK73G1HTTCM7500F for RK73G1HTTC7500F in existing designs.

The substitute part is available in higher inventory (940 Pcs vs. 723 Pcs), supporting improved supply chain continuity for ongoing production and new design initiatives.

Frequently Asked Questions (FAQ)

Q: Can RK73G1HTTCM7500F be used as a direct replacement for RK73G1HTTC7500F without PCB modification?

A: Yes. All electrical parameters (750 Ohms ±1%, 0.05W), mechanical dimensions (0201 package, 0.60mm x 0.30mm), and thermal specifications (-55°C ~ 155°C, ±50ppm/°C) are identical. No PCB layout changes are required.

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

A: The primary difference is product lifecycle status. RK73G1HTTC7500F is designated Not For New Designs, while RK73G1HTTCM7500F is Active. Both parts are manufactured by KOA Speer Electronics, Inc., belong to the RK73G series, and meet identical electrical and compliance specifications.

Q: Are both parts AEC-Q200 qualified?
