Key Parameters

Substitute Part Grouping Explanation

Substitution of the RK73B1HTTC682G is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Resistance value: 6.8 kOhms
• Tolerance: ±2%
• Power rating: 0.05W (1/20W)
• Temperature coefficient: ±200ppm/°C
• Operating temperature range: -55°C ~ 155°C

Mechanical Parameters:

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

Compliance & Certification:

• Automotive AEC-Q200 rating
• ROHS3 compliance
• Moisture Sensitivity Level 1

Substitute parts must match all electrical specifications, maintain identical package dimensions, and retain all automotive and environmental certifications. The composition (thick film) and series designation (RK73B) further define the substitution scope.

Parameter Comparison

Engineering Selection Recommendations

The RK73B1HTTCM682G is the direct equivalent substitute for the RK73B1HTTC682G. Both parts are manufactured by KOA Speer Electronics, Inc. and share identical electrical, mechanical, and compliance specifications.

The primary distinction between these parts is product status: the RK73B1HTTC682G is designated "Not For New Designs," while the RK73B1HTTCM682G carries an "Active" status. This status difference indicates that the RK73B1HTTCM682G represents the current production equivalent and is the recommended selection for ongoing applications.

Both parts maintain full AEC-Q200 automotive qualification, ROHS3 compliance, and identical performance characteristics across all operating conditions. The substitution is electrically and mechanically transparent, with no design modifications required.

Frequently Asked Questions (FAQ)

Q: Can the RK73B1HTTCM682G be used as a direct replacement for the RK73B1HTTC682G?

A: Yes. The RK73B1HTTCM682G is a direct equivalent substitute. All electrical parameters (resistance, tolerance, power rating, temperature coefficient), mechanical dimensions, package format, and automotive certifications are identical between the two parts.

Q: What is the significance of the "Not For New Designs" status on the RK73B1HTTC682G?

A: This designation indicates that the RK73B1HTTC682G is obsolete or being phased out by the manufacturer. The RK73B1HTTCM682G, with "Active" status, is the current production equivalent and should be used for new applications and ongoing procurement.

Q: Are there any differences in package or physical dimensions between these parts?

A: No. Both parts use the 0201 (0603 Metric) package format with identical dimensions of 0.024" L x 0.012" W (0.60mm x 0.30mm) and a maximum seated height of 0.010" (0.26mm). They are mechanically interchangeable.

Q: Do both parts meet automotive qualification requirements?

A: Yes. Both the RK73B1HTTC682G and RK73B1HTTCM682G are rated to the AEC-Q200 automotive standard and are suitable for automotive applications across the operating temperature range of -55°C to 155°C.

Q: What is the difference between the part numbers RK73B1HTTC682G and RK73B1HTTCM682G?

A: The difference is indicated by the "M" character in the RK73B1HTTCM682G designation. This character typically denotes a manufacturing or packaging variant within the same electrical specification family. Both parts are functionally equivalent with identical electrical and mechanical properties.

Q: Are both parts RoHS compliant?

A: Yes. Both parts are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic component manufacturing and use.
