Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RK73G1HTTC2701F is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Resistance value: 2.7 kOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 0.05W / 1/20W (exact match required)
• Temperature coefficient: ±50ppm/°C (exact match required)
• Operating temperature range: -55°C ~ 155°C (exact match required)

Mechanical Parameters:

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

Compliance & Certification:

• Automotive AEC-Q200 qualification (required for automotive applications)
• RoHS3 compliance (required for regulatory adherence)
• Moisture Sensitivity Level 1 (required for handling and storage compatibility)

Substitute parts must match all parameters listed above. Parts meeting these criteria are functionally and mechanically interchangeable within the original application circuit.

Parameter Comparison

Engineering Selection Recommendations

The RK73G1HTTCM2701F serves as the direct equivalent substitute for the RK73G1HTTC2701F. Both parts 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 original RK73G1HTTC2701F is designated "Not For New Designs," while the substitute RK73G1HTTCM2701F maintains "Active" status within the manufacturer's current product portfolio. This transition reflects standard manufacturer practices for component lifecycle management.

Both parts maintain full AEC-Q200 automotive qualification, ROHS3 compliance, and MSL 1 moisture sensitivity rating. Selection of the RK73G1HTTCM2701F ensures continued access to an actively supported component with identical performance characteristics and regulatory compliance for automotive applications operating across -55°C to 155°C.

Frequently Asked Questions (FAQ)

Q: Can the RK73G1HTTCM2701F be used as a direct replacement for RK73G1HTTC2701F in existing designs?

A: Yes. Both parts are electrically and mechanically identical with matching 2.7 kOhms resistance, ±1% tolerance, 0.05W power rating, 0201 package, and AEC-Q200 automotive qualification. The substitute part is functionally interchangeable in all circuit applications.

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

A: This designation indicates the RK73G1HTTC2701F has been superseded in the manufacturer's active product line. The RK73G1HTTCM2701F represents the current active equivalent. For new design work, the active substitute part is the appropriate selection.

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

A: No. Both parts share identical 0201 (0603 Metric) package dimensions, MSL 1 moisture sensitivity rating, and handling requirements. Packaging specifications, storage conditions, and assembly processes remain unchanged.

Q: Do both parts meet automotive compliance requirements?

A: Yes. Both the RK73G1HTTC2701F and RK73G1HTTCM2701F carry AEC-Q200 automotive qualification and ROHS3 compliance. REACH status is unaffected for both parts.

Q: What is the temperature coefficient specification, and does it differ between parts?

A: Both parts specify ±50ppm/°C temperature coefficient with operating range -55°C to 155°C. Temperature stability characteristics are identical.

Q: Are there any electrical performance differences between the two part numbers?

A: No. Resistance value, tolerance, power rating, and temperature coefficient are identical. Electrical performance in circuit applications is equivalent.
