Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RK73B1HTTC130G is determined by strict equivalence across the following critical parameters:

Electrical Specifications: Resistance value (13 Ohms), tolerance (±2%), and power rating (0.05W) must be identical. Temperature coefficient (±200ppm/°C) and operating temperature range (-55°C ~ 155°C) establish thermal performance boundaries.

Mechanical Specifications: 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.

Composition & Construction: Thick film technology and composition type must be consistent.

Compliance & Ratings: AEC-Q200 automotive qualification, RoHS3 compliance, and MSL 1 rating are mandatory for substitution in automotive applications.

Product Status Consideration: While the main part is classified as Not For New Designs, active equivalent parts with identical specifications provide continuity for existing designs and production support.

Parameter Comparison

Engineering Selection Recommendations

The RK73B1HTTCM130G serves as the direct active equivalent to the RK73B1HTTC130G. Both parts are manufactured by KOA Speer Electronics within the RK73B series and maintain identical electrical, mechanical, and thermal specifications. The substitute part differs only in product status classification, with RK73B1HTTCM130G designated as Active while the main part is Not For New Designs.

For applications requiring AEC-Q200 automotive qualification, RoHS3 compliance, and the specified 13 Ohm ±2% 0.05W thick film resistor in 0201 package, the RK73B1HTTCM130G provides full functional and physical compatibility. The active status of the substitute part ensures continued availability and manufacturing support for production requirements.

Both parts maintain identical compliance certifications (REACH Unaffected, EAR99 ECCN classification) and moisture sensitivity ratings (MSL 1 - Unlimited), confirming suitability for automotive and industrial applications without additional environmental controls.

Frequently Asked Questions (FAQ)

Q: Can RK73B1HTTCM130G be used as a direct replacement for RK73B1HTTC130G in existing designs?

A: Yes. The RK73B1HTTCM130G is electrically and mechanically identical to the RK73B1HTTC130G. Both parts share the same 13 Ohm resistance, ±2% tolerance, 0.05W power rating, 0201 package dimensions, and AEC-Q200 automotive qualification. Direct substitution is valid for all applications.

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

A: This classification indicates that the RK73B1HTTC130G is in mature or end-of-life phase and should not be selected for new product development. The RK73B1HTTCM130G, designated as Active, is the recommended choice for new designs while providing equivalent performance for existing applications.

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

A: Both parts are supplied in 0201 package format with identical physical dimensions (0.024" L x 0.012" W / 0.60mm x 0.30mm) and maximum seated height (0.010" / 0.26mm). Both maintain MSL 1 rating, requiring no special moisture control during storage or handling.

Q: Do both parts meet automotive qualification requirements?

A: Yes. Both RK73B1HTTC130G and RK73B1HTTCM130G carry AEC-Q200 qualification, confirming suitability for automotive applications. Both are ROHS3 compliant and REACH unaffected.

Q: What is the difference between the part numbers RK73B1HTTC130G and RK73B1HTTCM130G?

A: The difference is indicated by the "M" character in the middle of the part number (HTTC vs HTTCM). This designation reflects the product status change from Not For New Designs to Active, while all electrical and mechanical specifications remain identical.
