Key Parameters

Substitute Part Grouping Explanation

Substitution of the RK73G1HTTC9100F is determined by strict equivalence across the following critical parameters:

Electrical Specifications: Resistance value (910 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 Specifications: Package type (0201 / 0603 Metric), physical dimensions (0.024" L x 0.012" W / 0.60mm x 0.30mm), and seated height (0.010" / 0.26mm maximum) ensure physical compatibility with PCB layouts and assembly processes.

Compliance & Ratings: AEC-Q200 automotive qualification, ROHS3 compliance, and Moisture Sensitivity Level 1 are mandatory for applications requiring automotive-grade reliability and regulatory adherence.

Composition: Thick film construction maintains consistent performance characteristics across the specified temperature range.

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

Parameter Comparison

Engineering Selection Recommendations

The RK73G1HTTCM9100F is a direct equivalent substitute for the RK73G1HTTC9100F. Both components are manufactured by KOA Speer Electronics, Inc., within the RK73G series, and share identical electrical, mechanical, and thermal specifications.

The primary distinction is product lifecycle status: the main part (RK73G1HTTC9100F) is designated Not For New Designs, while the substitute (RK73G1HTTCM9100F) maintains Active status. This transition reflects standard component lifecycle management and does not indicate any change in performance, reliability, or compliance characteristics.

Both parts maintain full AEC-Q200 automotive qualification, ROHS3 compliance, and unlimited moisture sensitivity rating (MSL 1). Selection of the substitute part is appropriate for new production, redesigns, and long-term supply chain continuity while maintaining identical circuit performance and regulatory compliance.

Frequently Asked Questions (FAQ)

Q: Can RK73G1HTTCM9100F be used as a direct replacement for RK73G1HTTC9100F in existing designs?

A: Yes. Both parts are electrically and mechanically identical. The substitute part maintains the same 910 Ohms resistance, ±1% tolerance, 0.05W power rating, 0201 package, and AEC-Q200 automotive qualification. No circuit modifications or re-validation are required.

Q: What is the significance of the product status change from "Not For New Designs" to "Active"?

A: Product status reflects component lifecycle management by the manufacturer. The Active status of the substitute part indicates continued manufacturing support and availability for new production applications. The change does not affect electrical performance, reliability, or compliance.

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

A: Both parts share 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 Moisture Sensitivity Level 1 (Unlimited), requiring no special storage or handling precautions beyond standard component practices.

Q: Do both parts meet automotive qualification requirements?

A: Yes. Both RK73G1HTTC9100F and RK73G1HTTCM9100F are AEC-Q200 qualified and suitable for automotive applications requiring this certification standard.

Q: Is the substitute part ROHS3 compliant?

A: Yes. The RK73G1HTTCM9100F is ROHS3 compliant and REACH unaffected, matching the compliance profile of the main part.
