Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RK73B1HTTC200G is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Resistance value: 20 Ohms (exact match required)
• Tolerance: ±2% (exact match required)
• Power rating: 0.05W / 1/20W (exact match required)
• Temperature coefficient: ±200ppm/°C (exact match required)
• Operating temperature range: -55°C ~ 155°C (exact match required)

Mechanical Parameters:

• Package type: 0201 (0603 Metric) (exact match required)
• Composition: Thick Film (exact match required)

Compliance Parameters:

• Automotive qualification: AEC-Q200 (exact match required)
• RoHS compliance: ROHS3 Compliant (exact match required)
• Moisture sensitivity: MSL 1 (exact match required)

Only components meeting all specified parameters are considered valid substitutes. The primary distinction between the main part and substitute candidates is product status and availability.

Parameter Comparison

Engineering Selection Recommendations

The RK73B1HTTCM200G is a direct functional equivalent to the RK73B1HTTC200G. Both components are manufactured by KOA Speer Electronics, Inc., within the RK73B series, and share identical electrical, mechanical, and compliance specifications.

The primary distinction is product lifecycle status: RK73B1HTTC200G is designated "Not For New Designs," while RK73B1HTTCM200G maintains "Active" status. For applications requiring ongoing component procurement, the RK73B1HTTCM200G is the appropriate selection. Both parts maintain equivalent AEC-Q200 automotive qualification, ROHS3 compliance, and MSL 1 moisture sensitivity rating, ensuring compatibility in automotive and industrial applications operating across the -55°C to 155°C temperature range.

Frequently Asked Questions (FAQ)

Q: Can RK73B1HTTCM200G be used as a direct replacement for RK73B1HTTC200G?

A: Yes. Both components are electrically and mechanically identical, with matching 20 Ohm resistance, ±2% tolerance, 0.05W power rating, 0201 package, and AEC-Q200 automotive qualification. The substitute part is the recommended selection for new procurement due to its active product status.

Q: Are there any differences in package dimensions between these parts?

A: No. Both parts use the 0201 (0603 Metric) package with identical dimensions: 0.024" L x 0.012" W (0.60mm x 0.30mm) and maximum seated height of 0.010" (0.26mm).

Q: Do both parts meet the same automotive and compliance standards?

A: Yes. Both RK73B1HTTC200G and RK73B1HTTCM200G are AEC-Q200 qualified, ROHS3 compliant, and carry MSL 1 (Unlimited) moisture sensitivity rating. They are suitable for identical automotive and industrial applications.

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

A: This designation indicates that RK73B1HTTC200G is in the mature or end-of-life phase of its product lifecycle. While existing inventory remains available, KOA Speer Electronics recommends using RK73B1HTTCM200G for new designs and ongoing production to ensure long-term supply continuity.

Q: Are the temperature coefficients identical?

A: Yes. Both parts have a temperature coefficient of ±200ppm/°C and operate across the identical temperature range of -55°C to 155°C.
