Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RK73H1HTTC7682D is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Resistance value: 76.8 kOhms (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 to 155°C (exact match required)

Mechanical & Package Parameters:

• Package type: 0201 (0603 Metric) (exact match required)
• Composition: Thick Film (exact match required)
• Number of terminations: 2 (exact match required)
• Physical dimensions: 0.024" L x 0.012" W / 0.60mm x 0.30mm (exact match required)
• Height seated maximum: 0.010" / 0.26mm (exact match required)

Compliance & Environmental Parameters:

• Automotive qualification: AEC-Q200 (exact match required)
• Moisture resistance: Yes (exact match required)
• RoHS compliance: ROHS3 Compliant (exact match required)
• Moisture Sensitivity Level: MSL 1 (exact match required)

Substitute parts must match all parameters listed above. Product status differences (active versus not for new designs) do not affect functional substitutability when all electrical, mechanical, and compliance parameters are identical.

Parameter Comparison

Engineering Selection Recommendations

The RK73H1HTTCM7682D qualifies as a direct functional equivalent to the RK73H1HTTC7682D based on complete parameter alignment across all electrical, mechanical, and compliance specifications.

Selection Basis:

The substitute part RK73H1HTTCM7682D maintains identical electrical performance characteristics: 76.8 kOhms resistance with ±0.5% tolerance, 0.05W power rating, and ±200ppm/°C temperature coefficient across the -55°C to 155°C operating range. Mechanical compatibility is confirmed through identical 0201 package dimensions and termination configuration.

Compliance certifications are equivalent: both parts carry AEC-Q200 automotive qualification, ROHS3 compliance, and MSL 1 moisture sensitivity rating. Both incorporate moisture-resistant thick film construction suitable for automotive and industrial applications.

The primary distinction is product status: RK73H1HTTCM7682D carries "Active" status, indicating current manufacturing and availability, whereas RK73H1HTTC7682D is marked "Not For New Designs." This status difference reflects manufacturing lifecycle positioning and does not affect functional interchangeability in existing circuit applications.

Frequently Asked Questions (FAQ)

Q: Can RK73H1HTTCM7682D be used as a direct replacement for RK73H1HTTC7682D in existing designs?

A: Yes. The RK73H1HTTCM7682D is electrically and mechanically equivalent to RK73H1HTTC7682D. All critical parameters including resistance value, tolerance, power rating, package dimensions, temperature characteristics, and automotive certifications are identical. Direct substitution is supported without circuit modification.

Q: What is the significance of the "Not For New Designs" status on RK73H1HTTC7682D?

A: "Not For New Designs" indicates the part has been superseded in the manufacturer's active product portfolio. This status applies to legacy components and does not affect performance in existing applications. The RK73H1HTTCM7682D, marked as "Active," represents the current production equivalent.

Q: Are the physical dimensions identical between these two parts?

A: Yes. Both parts are packaged in 0201 (0603 metric) format with identical dimensions of 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 are interchangeable.

Q: Do both parts meet the same automotive and compliance standards?

A: Yes. Both RK73H1HTTC7682D and RK73H1HTTCM7682D carry AEC-Q200 automotive qualification, ROHS3 compliance, and MSL 1 moisture sensitivity rating. Moisture-resistant thick film construction is identical in both parts.

Q: What is the difference between the part numbers RK73H1HTTC7682D and RK73H1HTTCM7682D?

A: The part numbers differ by a single character: "C" versus "CM" in the suffix. This designation reflects manufacturing code or revision level within the RK73H series. The electrical and mechanical specifications remain identical.

Q: Is there any performance difference in temperature coefficient or operating range?

A: No. Both parts specify ±200ppm/°C temperature coefficient and operate across the identical -55°C to 155°C temperature range. Thermal performance and stability characteristics are equivalent.

Q: Can these parts be mixed in the same production batch or assembly?

A: Yes. Since all electrical, mechanical, and compliance parameters are identical, both parts can be used interchangeably within the same design or production run without affecting circuit performance or reliability.
