RK73G1HTTC1502D Equivalent & Substitute Parts

Part Overview

The RK73G1HTTC1502D is a 15 kOhms ±0.5% thick film chip resistor manufactured by KOA Speer Electronics, Inc., designed for automotive applications with AEC-Q200 qualification. This 0201 package resistor delivers 0.05W (1/20W) power rating and operates across -55°C to 155°C temperature range.

The RK73G1HTTC1502D carries a "Not For New Designs" product status, indicating it has been superseded in the manufacturer's active product line. Identifying equivalent substitute parts ensures design continuity, maintains supply chain reliability, and provides access to actively supported alternatives with identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RK73G1HTTC1502D is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Resistance value: 15 kOhms (exact match required)
• Tolerance: ±0.5% (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 / Case: 0201 (0603 Metric) (exact match required)
• Composition: Thick Film (exact match required)

Compliance & Certification:

• Automotive AEC-Q200 qualification (exact match required)
• RoHS3 compliance (exact match required)
• Moisture Sensitivity Level 1 (exact match required)

Substitute parts must satisfy all parameters listed above. Parts differing in any electrical specification, package dimension, or automotive certification are not considered equivalent and cannot be used as direct replacements.

Parameter Comparison

Engineering Selection Recommendations

The RK73G1HTTCM1502D is the direct equivalent substitute for the RK73G1HTTC1502D. 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 lifecycle status: the RK73G1HTTC1502D is designated "Not For New Designs," while the RK73G1HTTCM1502D maintains "Active" status. This indicates the RK73G1HTTCM1502D represents the current production equivalent and is the recommended selection for ongoing designs and procurement.

Both parts satisfy AEC-Q200 automotive qualification, ROHS3 compliance, and REACH unaffected status. Substitution between these parts introduces no electrical, mechanical, or compliance risk. The RK73G1HTTCM1502D is suitable for direct replacement in existing designs using the RK73G1HTTC1502D.

Frequently Asked Questions (FAQ)

Q: Can the RK73G1HTTCM1502D replace the RK73G1HTTC1502D in existing designs?

A: Yes. The RK73G1HTTCM1502D is electrically and mechanically equivalent to the RK73G1HTTC1502D. Both parts deliver identical resistance (15 kOhms), tolerance (±0.5%), power rating (0.05W), temperature coefficient (±50ppm/°C), operating temperature range (-55°C ~ 155°C), and package dimensions (0201 / 0603 Metric). No circuit redesign or board layout modification is required.

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

A: "Not For New Designs" indicates the manufacturer has transitioned this part number to end-of-life status and recommends using the active equivalent for new applications. Existing inventory may remain available, but long-term supply cannot be guaranteed. The RK73G1HTTCM1502D is the active production equivalent.

Q: Are there any compliance differences between these parts?

A: No. Both parts are ROHS3 compliant, REACH unaffected, and carry AEC-Q200 automotive qualification. Moisture Sensitivity Level is 1 (Unlimited) for both parts. No compliance risk exists in substitution.

Q: Do these parts have identical physical dimensions?

A: Yes. Both parts use the 0201 package (0603 Metric), with dimensions of 0.024" L x 0.012" W (0.60mm x 0.30mm) and maximum seated height of 0.010" (0.26mm). PCB footprints and assembly processes are identical.

Q: What is the temperature coefficient specification, and does it differ between parts?

A: Both parts specify ±50ppm/°C temperature coefficient. This parameter is identical and ensures equivalent performance across the -55°C ~ 155°C operating range.
