Electrical Parameters:

• Resistance value: 68 kOhms
• Tolerance: ±0.5%
• Power rating: 0.05W (1/20W)
• Temperature coefficient: ±50ppm/°C
• Operating temperature range: -55°C ~ 155°C

Mechanical Parameters:

• Package format: 0201 (0603 Metric)
• Number of terminations: 2
• Physical dimensions: 0.024" L x 0.012" W (0.60mm x 0.30mm)
• Maximum seated height: 0.010" (0.26mm)

Compliance & Certification:

• Automotive AEC-Q200 rating

Substitute parts must match all electrical specifications, maintain identical package dimensions, and retain automotive-grade certification. The RK73G series designation confirms manufacturer lineage and design compatibility.

Parameter Comparison

Engineering Selection Recommendations

The RK73G1HTTCM6802D is the direct substitute for the RK73G1HTTC6802D. Both components are manufactured by KOA Speer Electronics, Inc. within the RK73G series and share identical electrical and mechanical specifications.

The primary distinction is product status: the original part number (RK73G1HTTC6802D) is designated "Not For New Designs," while the substitute (RK73G1HTTCM6802D) maintains "Active" status. This transition ensures access to current manufacturing inventory and ongoing supplier support.

Both parts maintain full AEC-Q200 automotive qualification, ROHS3 compliance, and unlimited moisture sensitivity rating (MSL 1). The electrical performance, package dimensions, and thermal characteristics are equivalent across all specified parameters.

For applications currently using RK73G1HTTC6802D, transition to RK73G1HTTCM6802D is supported without circuit redesign or performance degradation.

Frequently Asked Questions (FAQ)

Q: Can RK73G1HTTCM6802D be used as a direct replacement for RK73G1HTTC6802D?

A: Yes. Both parts are electrically and mechanically identical. They share the same resistance value (68 kOhms), tolerance (±0.5%), power rating (0.05W), package format (0201), temperature coefficient (±50ppm/°C), and operating range (-55°C ~ 155°C). Both carry AEC-Q200 automotive certification.

Q: What is the difference between these two part numbers?

A: The RK73G1HTTC6802D is designated "Not For New Designs," indicating end-of-life status. The RK73G1HTTCM6802D is the active equivalent with current manufacturing support. The "M" designation in the part number reflects the current production variant.

Q: Are there any compliance or certification differences?

A: No. Both parts are ROHS3 compliant, carry AEC-Q200 automotive ratings, and maintain Moisture Sensitivity Level 1 (unlimited). Regulatory and compliance status is identical.

Q: Will the substitute part fit existing PCB layouts?

A: Yes. Both components 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 are interchangeable.

Q: Is the temperature coefficient the same?

A: Yes. Both parts specify ±50ppm/°C temperature coefficient and operate across -55°C to 155°C. Thermal performance is equivalent.

Q: Can I use these parts interchangeably in automotive applications?

A: Yes. Both parts meet AEC-Q200 automotive standards. The substitute part maintains all automotive qualification requirements of the original part number.
