Key Parameters

Substitute Part Grouping Explanation

Substitution of the RK73H1HTTC86R6D is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Resistance value: 86.6 Ohms (exact match required)
• Tolerance: ±0.5% (no deviation permitted)
• Power rating: 0.05W / 1/20W (minimum requirement)
• Temperature coefficient: ±200ppm/°C (maximum allowable drift)
• Operating temperature range: -55°C ~ 155°C (full range coverage)

Mechanical & Package Parameters:

• Package type: 0201 (0603 Metric) form factor
• Composition: Thick Film construction
• Number of terminations: 2 (standard chip resistor configuration)
• Physical dimensions: 0.024" L x 0.012" W (0.60mm x 0.30mm)
• Height seated maximum: 0.010" (0.26mm)

Compliance & Certification:

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

Substitute parts must match all electrical specifications, maintain identical package geometry, and retain full automotive and environmental compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The RK73H1HTTCM86R6D is the direct substitute for the RK73H1HTTC86R6D. Both components are manufactured by KOA Speer Electronics, Inc., within the RK73H series, and maintain identical electrical, mechanical, and compliance specifications.

Key Selection Criteria:

The primary distinction between the main part and substitute is product lifecycle status. The RK73H1HTTC86R6D is classified as "Not For New Designs," indicating manufacturer discontinuation or transition. The RK73H1HTTCM86R6D carries "Active" status, confirming ongoing production and long-term availability.

Both parts satisfy identical requirements for:

• Automotive applications requiring AEC-Q200 qualification
• Thick film resistor construction with ±200ppm/°C temperature stability
• Full temperature range operation from -55°C to 155°C
• ROHS3 compliance and unlimited moisture sensitivity rating
• 0201 package form factor with 0.05W power dissipation capability

For new designs and ongoing production, the RK73H1HTTCM86R6D is the appropriate selection due to active product status and assured supply continuity. Existing designs using the RK73H1HTTC86R6D may transition to the substitute without circuit modification or re-qualification, as all functional and mechanical parameters remain unchanged.

Frequently Asked Questions (FAQ)

Q: Can the RK73H1HTTCM86R6D be used as a direct replacement for the RK73H1HTTC86R6D in existing designs?

A: Yes. Both components are electrically and mechanically identical. The RK73H1HTTCM86R6D provides direct substitution with no circuit modifications required. The primary difference is product status: the substitute is actively manufactured, while the original is not recommended for new designs.

Q: Are there any differences in the 0201 package dimensions between these parts?

A: No. Both parts conform to identical 0201 (0603 Metric) package specifications: 0.024" L x 0.012" W (0.60mm x 0.30mm) with maximum seated height of 0.010" (0.26mm). PCB footprints and assembly processes remain unchanged.

Q: Do both parts maintain AEC-Q200 automotive qualification?

A: Yes. Both the RK73H1HTTC86R6D and RK73H1HTTCM86R6D carry full AEC-Q200 qualification, meeting automotive reliability and environmental stress testing requirements. Both are suitable for automotive and high-reliability industrial applications.

Q: What is the significance of the product status difference?

A: The RK73H1HTTC86R6D is marked "Not For New Designs," indicating the manufacturer has transitioned this part number. The RK73H1HTTCM86R6D is "Active," confirming ongoing production and supply availability. For new designs, the active substitute ensures long-term component availability and manufacturer support.

Q: Are the tolerance and temperature coefficient specifications identical?

A: Yes. Both parts specify ±0.5% tolerance and ±200ppm/°C temperature coefficient. Electrical performance and stability characteristics are equivalent across the full -55°C to 155°C operating range.

Q: Is there any difference in RoHS or REACH compliance?

A: No. Both parts are ROHS3 Compliant and REACH Unaffected. Environmental and regulatory compliance status is identical.
