Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RK73G1HTTC3301D is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 3.3 kOhms
• Tolerance: ±0.5%
• Power rating: 0.05W (1/20W)
• Package: 0201 (0603 Metric)
• Composition: Thick Film
• Temperature coefficient: ±50ppm/°C
• Operating temperature range: -55°C ~ 155°C
• Automotive qualification: AEC-Q200
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity: MSL 1

Substitute parts must satisfy all parameters listed above without deviation. Parts meeting these criteria are electrically and mechanically interchangeable within the original application context.

Parameter Comparison

Engineering Selection Recommendations

The RK73G1HTTCM3301D serves as the direct equivalent substitute for the RK73G1HTTC3301D. Both components are manufactured by KOA Speer Electronics, Inc., and maintain identical electrical and mechanical specifications across all critical parameters.

The primary distinction between these parts is product lifecycle status: the original RK73G1HTTC3301D is designated "Not For New Designs," while the substitute RK73G1HTTCM3301D maintains "Active" status within the manufacturer's current product portfolio. This status change reflects standard manufacturer practices for component lifecycle management and does not indicate functional or performance differences.

Both parts carry AEC-Q200 automotive qualification, ROHS3 compliance, and MSL 1 moisture sensitivity rating, confirming suitability for automotive and industrial applications requiring environmental robustness and regulatory adherence.

Selection of the RK73G1HTTCM3301D is appropriate for applications currently using the RK73G1HTTC3301D, as well as for new designs requiring a 3.3 kOhms ±0.5% 0.05W 0201 thick film chip resistor with automotive-grade specifications.

Frequently Asked Questions (FAQ)

Q: Can the RK73G1HTTCM3301D replace the RK73G1HTTC3301D in existing designs?

A: Yes. Both components are electrically and mechanically identical across all specified parameters, including resistance, tolerance, power rating, package dimensions, temperature range, and automotive qualification. Direct substitution is supported without circuit modification.

Q: What does "Not For New Designs" status mean for the original part?

A: This designation indicates the RK73G1HTTC3301D has been superseded in the manufacturer's active product line. The substitute RK73G1HTTCM3301D represents the current production equivalent. For ongoing production and new applications, the substitute part is the recommended selection.

Q: Are there any differences in reliability or performance between these parts?

A: No. Both components meet identical AEC-Q200 automotive qualification standards, carry the same temperature coefficient (±50ppm/°C), and operate across the same temperature range (-55°C ~ 155°C). Performance characteristics are equivalent.

Q: Do both parts meet the same compliance requirements?

A: Yes. Both the RK73G1HTTC3301D and RK73G1HTTCM3301D are ROHS3 compliant, REACH unaffected, and carry MSL 1 moisture sensitivity rating. Regulatory and environmental compliance is identical.

Q: Can these parts be used interchangeably in PCB assembly?

A: Yes. Identical package specifications (0201 / 0603 Metric), dimensions (0.024" L x 0.012" W), and termination count (2) ensure mechanical and assembly compatibility. No PCB layout or assembly process modifications are required.

Q: What is the tolerance specification, and how does it affect circuit performance?

A: Both parts carry ±0.5% tolerance on the 3.3 kOhms resistance value. This tolerance range is maintained across the full operating temperature range and represents the maximum deviation from the nominal resistance specification. Circuit designs must account for this tolerance in critical applications.

Q: Are there packaging differences between the original and substitute parts?

A: The original part is specified as Tape & Reel (TR) packaging. The substitute part packaging is not specified in the provided data. Confirm packaging requirements with the supplier to ensure compatibility with your procurement and assembly processes.
