Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RK73H1HTTC16R2D is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Resistance value: 16.2 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 & Package Parameters:

• Package format: 0201 (0603 Metric) (exact match required)
• Composition: Thick Film (exact match required)
• Number of terminations: 2 (exact match required)

Compliance & Certification Parameters:

• Automotive rating: AEC-Q200 (exact match required)
• RoHS status: ROHS3 Compliant (exact match required)
• Moisture Sensitivity Level: 1 (Unlimited) (exact match required)

Substitute parts must maintain identical electrical performance, physical dimensions, and regulatory compliance. Differences in product status (Active vs. Not For New Designs) do not affect functional substitutability.

Parameter Comparison

Engineering Selection Recommendations

The RK73H1HTTCM16R2D is a direct functional equivalent to the RK73H1HTTC16R2D. Both parts are manufactured by KOA Speer Electronics, Inc. within the RK73H series and share identical electrical specifications, mechanical dimensions, and regulatory compliance certifications.

The primary distinction between these parts is product status: the main part (RK73H1HTTC16R2D) is classified as Not For New Designs, while the substitute (RK73H1HTTCM16R2D) maintains Active status. This status difference reflects the manufacturer's product lifecycle management and does not indicate any functional or performance divergence.

Both parts satisfy AEC-Q200 automotive qualification requirements, maintain ROHS3 compliance, and carry unlimited moisture sensitivity rating (MSL 1). The substitute part is suitable for direct replacement in applications currently using the main part number, including automotive and industrial systems operating across the -55°C to 155°C temperature range.

Frequently Asked Questions (FAQ)

Q: Can RK73H1HTTCM16R2D replace RK73H1HTTC16R2D in existing designs?

A: Yes. The substitute part is electrically and mechanically identical. All critical parameters including resistance, tolerance, power rating, package dimensions, temperature coefficient, and automotive certification match exactly. Direct substitution is supported.

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

A: This designation indicates the manufacturer has transitioned the part to end-of-life status and recommends using the Active substitute part (RK73H1HTTCM16R2D) for new applications. Existing inventory of the main part remains available for legacy system support and maintenance.

Q: Are there any differences in moisture handling between these parts?

A: No. Both parts carry identical Moisture Sensitivity Level 1 (Unlimited) rating, indicating no moisture sensitivity restrictions for either part.

Q: Do both parts meet automotive standards?

A: Yes. Both the RK73H1HTTC16R2D and RK73H1HTTCM16R2D are AEC-Q200 qualified for automotive applications and maintain identical operating temperature ranges of -55°C to 155°C.

Q: Can these parts be used interchangeably on PCBs?

A: Yes. Both parts use the 0201 (0603 Metric) package with identical physical dimensions (0.024" L x 0.012" W, 0.60mm x 0.30mm) and maximum seated height of 0.010" (0.26mm). PCB footprints and assembly processes require no modification.

Q: What is the difference in packaging between these parts?

A: The main part is supplied in Tape & Reel (TR) format. Packaging information for the substitute part was not provided in the available data. Confirm packaging requirements with the supplier before procurement.

Q: Are both parts RoHS compliant?

A: Yes. Both parts are ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory requirements.
