Key Parameters

Substitute Part Grouping Explanation

Substitution of the RK73H1HTTC7151D is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 7.15 kOhms (exact match required)
• Tolerance: ±0.5% (precision class must be maintained)
• Power rating: 0.05W / 1/20W (thermal capacity must be equal or greater)
• Package format: 0201 (0603 Metric) (physical and electrical footprint compatibility)
• Composition: Thick Film (manufacturing process consistency)
• Temperature coefficient: ±200ppm/°C (temperature stability specification)
• Operating temperature range: -55°C to 155°C (environmental capability)
• Automotive rating: AEC-Q200 (quality and reliability standard)
• RoHS compliance: ROHS3 Compliant (regulatory conformance)

The substitute part RK73H1HTTCM7151D meets all mandatory parameters while offering improved product status (Active vs. Not For New Designs) and enhanced moisture resistance features.

Parameter Comparison

Engineering Selection Recommendations

Electrical Equivalence: Resistance value, tolerance, power rating, temperature coefficient, and operating temperature range are identical. Direct substitution in circuit designs requires no recalculation or revalidation of electrical performance.

Physical Compatibility: Package format, dimensions, and termination configuration are identical. PCB footprints and assembly processes require no modification.

Supply Chain Consideration: The substitute part shows higher inventory availability (1028 Pcs vs. 660 Pcs), supporting procurement reliability and lead time reduction.

Frequently Asked Questions (FAQ)

Q: Can RK73H1HTTCM7151D be used as a direct replacement for RK73H1HTTC7151D in existing designs?

A: Yes. All electrical parameters, mechanical dimensions, package format, and regulatory certifications are identical. Direct substitution is supported without design modification or revalidation.

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

A: This designation indicates the manufacturer has transitioned the product to end-of-life status and recommends using the substitute part for new design work. Existing inventory may remain available, but long-term supply cannot be guaranteed.

Q: Are there any differences in moisture resistance between the two parts?

A: Both parts are moisture resistant with MSL 1 (Unlimited) rating. Handling and storage requirements are identical.

Q: Does the substitute part maintain AEC-Q200 automotive qualification?

A: Yes. The substitute part carries identical AEC-Q200 qualification, maintaining automotive-grade reliability standards.

Q: Is there any difference in RoHS or REACH compliance?

A: No. Both parts are ROHS3 Compliant and REACH Unaffected. Regulatory status is identical.

Q: Can the 0201 package be used interchangeably with other package sizes?

A: No. The 0201 (0603 Metric) package is a specific form factor. PCB footprints and assembly equipment are designed for this package size. Substitution with different package sizes requires design and manufacturing process changes.

Q: What is the temperature coefficient specification, and why does it matter?

A: The ±200ppm/°C temperature coefficient specifies how the resistance value changes with temperature. Both parts maintain identical stability, ensuring consistent circuit performance across the -55°C to 155°C operating range.

Q: Is the substitute part available in the same packaging format (Tape & Reel)?

A: The substitute part packaging information is not specified in the provided data. Confirm packaging format with the supplier before procurement to ensure compatibility with automated assembly processes.
