RK73G1HTTC7502F Equivalent & Substitute Parts

Part Overview

The RK73G1HTTC7502F is a 75 kOhms ±1% thick film chip resistor manufactured by KOA Speer Electronics, Inc. in the 0201 (0603 Metric) package format. This component is rated for automotive applications under AEC-Q200 standards with a power rating of 0.05W (1/20W) and operates across the temperature range of -55°C to 155°C.

The RK73G1HTTC7502F carries a product status designation of "Not For New Designs," indicating that while the part remains available in inventory, it has been superseded in the manufacturer's active product line. Identifying equivalent substitute parts is necessary for design continuity, long-term supply chain planning, and transition to actively supported alternatives that maintain identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RK73G1HTTC7502F is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Resistance value: 75 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 format: 0201 (0603 Metric) (exact match required)
• Composition: Thick Film (exact match required)

Compliance & Certification:

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

Substitute parts must satisfy all parameters listed above without deviation. The primary distinction between the main part and its substitute is product status and availability, not electrical or mechanical performance.

Parameter Comparison

Engineering Selection Recommendations

The RK73G1HTTCM7502F is a direct functional equivalent to the RK73G1HTTC7502F. Both parts are manufactured by KOA Speer Electronics, Inc., belong to the RK73G series, and share identical electrical specifications, mechanical dimensions, and automotive compliance certifications.

The primary distinction is product lifecycle status: RK73G1HTTC7502F is designated "Not For New Designs," while RK73G1HTTCM7502F carries "Active" status. This indicates that RK73G1HTTCM7502F represents the current production standard within the KOA Speer Electronics product line for this specification.

For applications requiring long-term supply chain stability and manufacturer support, RK73G1HTTCM7502F is the appropriate selection. Both parts maintain ROHS3 compliance, AEC-Q200 automotive qualification, and identical performance characteristics across the full operating temperature range of -55°C to 155°C.

Frequently Asked Questions (FAQ)

Q: Can RK73G1HTTCM7502F be used as a direct replacement for RK73G1HTTC7502F in existing designs?

A: Yes. Both parts are electrically and mechanically identical. They share the same resistance value (75 kOhms), tolerance (±1%), power rating (0.05W), package format (0201), temperature coefficient (±50ppm/°C), operating range (-55°C to 155°C), and automotive AEC-Q200 certification. No circuit modifications or re-qualification are required.

Q: What is the significance of the "Not For New Designs" status on RK73G1HTTC7502F?

A: This designation indicates that the manufacturer has transitioned this part to end-of-life status and is no longer recommending it for new product development. However, existing inventory remains available. For new designs or long-term production commitments, RK73G1HTTCM7502F (Active status) is the recommended alternative.

Q: Are the physical dimensions identical between these two parts?

A: Yes. Both parts are packaged in the 0201 (0603 Metric) format with 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 footprint-compatible on PCB layouts.

Q: Do both parts meet automotive qualification requirements?

A: Yes. Both RK73G1HTTC7502F and RK73G1HTTCM7502F are AEC-Q200 rated for automotive applications and maintain ROHS3 compliance with MSL 1 (Unlimited) moisture sensitivity rating.

Q: Is there a difference in temperature performance between these parts?

A: No. Both parts operate across the identical temperature range of -55°C to 155°C with the same temperature coefficient of ±50ppm/°C, ensuring equivalent thermal stability and performance characteristics.
