Key Parameters

Substitute Part Grouping Explanation

Substitution of the RK73G1HTTC6802F is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

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

Mechanical Parameters:

• Package type: 0201 (0603 Metric) (exact match required)
• Composition: Thick Film (exact match required)

Compliance & Certification:

• Automotive qualification: AEC-Q200 (exact match required)
• RoHS compliance: ROHS3 Compliant (exact match required)
• Moisture sensitivity: MSL 1 (exact match required)

Substitute parts must match all parameters listed above. Deviations in any electrical, mechanical, or compliance parameter disqualify a part from substitution eligibility.

Parameter Comparison

Engineering Selection Recommendations

The RK73G1HTTCM6802F is the direct equivalent substitute for the RK73G1HTTC6802F. Both parts are manufactured by KOA Speer Electronics, Inc., within the RK73G series, and share identical electrical specifications, mechanical dimensions, and automotive compliance certifications.

The primary distinction is product status: the original part (RK73G1HTTC6802F) is classified as "Not For New Designs," while the substitute (RK73G1HTTCM6802F) maintains "Active" status. This indicates the substitute represents the current production alternative within the manufacturer's portfolio.

For applications currently using RK73G1HTTC6802F, transition to RK73G1HTTCM6802F is supported by:

• Identical electrical performance across all specified parameters
• Matching mechanical package and footprint compatibility
• Equivalent AEC-Q200 automotive qualification
• Maintained ROHS3 compliance and MSL 1 rating
• Continued availability through active production status

No design modifications, circuit re-evaluation, or additional testing protocols are required when substituting between these two part numbers, as all functional and compliance parameters remain unchanged.

Frequently Asked Questions (FAQ)

Q: Can RK73G1HTTCM6802F be used as a direct replacement for RK73G1HTTC6802F in existing designs?

A: Yes. Both parts are electrically and mechanically identical. The substitute part carries active product status, making it the recommended choice for procurement and new production runs.

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

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

Q: Do both parts meet automotive qualification requirements?

A: Yes. Both RK73G1HTTC6802F and RK73G1HTTCM6802F carry AEC-Q200 qualification, confirming suitability for automotive applications across the specified operating temperature range of -55°C to 155°C.

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

A: This designation indicates the manufacturer has transitioned the part to end-of-life status and recommends using the active substitute (RK73G1HTTCM6802F) for new designs. Existing inventory of the original part may still be available but should not be specified for new development.

Q: Are the RoHS and REACH compliance statuses identical?

A: Yes. Both parts are ROHS3 Compliant and REACH Unaffected, maintaining equivalent environmental compliance across all regulatory frameworks.

Q: Is there any difference in moisture sensitivity or handling requirements?

A: No. Both parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions and identical storage and handling requirements.
