Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RK73H1HTTC2670D is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Resistance value: 267 Ohms (exact match required)
• Tolerance: ±0.5% (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 format: 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 conformance)
• Moisture Sensitivity Level MSL 1 (required for handling and storage compatibility)

Substitute parts must satisfy all electrical, mechanical, and compliance criteria without exception. Parts meeting these parameters are functionally and physically interchangeable within the specified operating conditions.

Parameter Comparison

Engineering Selection Recommendations

Key Differentiation:

The primary distinction between these parts is product lifecycle status. The RK73H1HTTC2670D is designated "Not For New Designs," indicating end-of-life phase management by the manufacturer. The RK73H1HTTCM2670D maintains "Active" product status, confirming ongoing manufacturing support and availability.

Compliance Basis:

Both parts maintain full AEC-Q200 automotive qualification, ROHS3 compliance, and MSL 1 moisture sensitivity rating. These certifications ensure compatibility with automotive supply chain requirements and regulatory frameworks applicable to both legacy and current production environments.

Supply Chain Consideration:

Current inventory data indicates 950 units of RK73H1HTTCM2670D available versus 784 units of RK73H1HTTC2670D. The substitute part's active status provides extended supply chain continuity for ongoing production requirements.

Frequently Asked Questions (FAQ)

Q: Can RK73H1HTTCM2670D be used as a direct replacement for RK73H1HTTC2670D in existing designs?

A: Yes. Both parts are electrically and mechanically identical across all specified parameters. The RK73H1HTTCM2670D is a direct substitute with no design modifications required. Physical footprint, electrical performance, and environmental ratings are equivalent.

Q: What is the significance of the "Not For New Designs" status on the RK73H1HTTC2670D?

A: This designation indicates that KOA Speer Electronics has transitioned the RK73H1HTTC2670D to end-of-life phase and is no longer recommending it for new product development. The RK73H1HTTCM2670D, with active status, is the manufacturer's current production equivalent and should be specified for new designs and ongoing production.

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

A: No. Both parts use identical 0201 (0603 Metric) package format with matching physical dimensions (0.024" L x 0.012" W / 0.60mm x 0.30mm) and height specifications (0.010" / 0.26mm maximum seated height). Both maintain MSL 1 moisture sensitivity rating, requiring identical storage and handling protocols.

Q: Do both parts meet automotive AEC-Q200 requirements?

A: Yes. Both RK73H1HTTC2670D and RK73H1HTTCM2670D carry AEC-Q200 automotive qualification. They are suitable for automotive applications requiring this certification standard.

Q: What is the tolerance specification for these resistors?

A: Both parts are specified at ±0.5% tolerance on the 267 Ohm resistance value. This tight tolerance is maintained across the full operating temperature range of -55°C to 155°C with a temperature coefficient of ±200ppm/°C.

Q: Are these parts RoHS compliant?

A: Yes. Both parts are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic component manufacturing and use.
