Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RK73H1HTTC3002D is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Resistance value: 30 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 ~ 155°C (exact match required)

Mechanical Parameters:

• Package format: 0201 (0603 Metric) (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 & Certification:

• Automotive rating: AEC-Q200 (required for automotive applications)
• RoHS compliance: ROHS3 Compliant (required for regulatory compliance)
• Moisture sensitivity: MSL 1 (Unlimited) (required for reliability)

Substitute parts must match all electrical, mechanical, and compliance parameters without exception. Composition type (Thick Film) and manufacturer series (RK73H) serve as additional confirmation of functional equivalence.

Parameter Comparison

Engineering Selection Recommendations

The RK73H1HTTCM3002D is the direct equivalent substitute for the RK73H1HTTC3002D. Both components are manufactured by KOA Speer Electronics, Inc. within the RK73H series and share identical electrical specifications, mechanical dimensions, and compliance certifications.

The primary distinction between these parts is product lifecycle status: the RK73H1HTTC3002D is designated "Not For New Designs," while the RK73H1HTTCM3002D maintains "Active" status.
