Substitute Part Grouping Explanation

Substitution of the RK73B1HTTC162G is determined by strict equivalence across the following electrical and mechanical parameters:

• Resistance Value: 1.6 kOhms (exact match required)
• Tolerance: ±2% (exact match required)
• Power Rating: 0.05W / 1/20W (exact match required)
• Package: 0201 (0603 Metric) (exact match required)
• Composition: Thick Film (exact match required)
• Temperature Coefficient: ±200ppm/°C (exact match required)
• Operating Temperature Range: -55°C ~ 155°C (exact match required)
• Automotive Compliance: AEC-Q200 (exact match required)
• RoHS Compliance: ROHS3 Compliant (exact match required)

Substitute parts must match all parameters listed above. Variations in any parameter disqualify a part from direct substitution.

Engineering Selection Recommendations

The RK73B1HTTCM162G is the direct equivalent substitute for the RK73B1HTTC162G. Both parts are manufactured by KOA Speer Electronics, Inc., belong to the RK73B series, and share identical electrical and mechanical specifications.

The primary distinction between these parts is product status: the original RK73B1HTTC162G is classified as "Not For New Designs," while the RK73B1HTTCM162G maintains "Active" status. This status change reflects the manufacturer's product lifecycle management and indicates that the RK73B1HTTCM162G is the current production equivalent.

For applications currently using RK73B1HTTC162G, transition to RK73B1HTTCM162G is supported by:

• Identical electrical performance across all specified parameters
• Matching automotive AEC-Q200 qualification
• Equivalent RoHS3 compliance and environmental ratings
• Same physical package dimensions and termination configuration
• Maintained temperature coefficient and operating range specifications

Selection of RK73B1HTTCM162G ensures continued compliance with automotive standards and access to active production inventory.

Frequently Asked Questions (FAQ)

Q: Can RK73B1HTTCM162G be used as a direct replacement for RK73B1HTTC162G?

A: Yes. Both parts are electrically and mechanically identical. The RK73B1HTTCM162G is the active production equivalent and serves as the direct substitute.

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

A: The parts are functionally equivalent. The primary difference is product lifecycle status: RK73B1HTTC162G is "Not For New Designs," while RK73B1HTTCM162G is "Active." The suffix variation in the part number reflects the manufacturer's product line management.
