Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RK73G1HTTC1502F is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Resistance value: 15 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 / Case: 0201 (0603 Metric) (exact match required)
• Composition: Thick Film (exact match required)

Compliance & Certification:

• Automotive AEC-Q200 qualification (required for automotive applications)
• RoHS3 compliance (required for regulatory conformance)
• Moisture Sensitivity Level 1 (required for storage and handling compatibility)

Substitute parts must match all electrical, mechanical, and compliance parameters without exception. The RK73G1HTTCM1502F meets all substitution criteria as a direct equivalent.

Parameter Comparison

Engineering Selection Recommendations

The RK73G1HTTCM1502F is the manufacturer-recommended substitute for the RK73G1HTTC1502F. Both parts are manufactured by KOA Speer Electronics, Inc., within the RK73G series, and provide identical electrical and mechanical specifications.

Selection Basis:

1. Product Status Alignment: The RK73G1HTTCM1502F carries an "Active" product status, indicating ongoing manufacturer support and availability. The main part RK73G1HTTC1502F is designated "Not For New Designs," making the substitute the appropriate choice for new production and long-term supply continuity.

2. Compliance Equivalence: Both parts maintain identical AEC-Q200 automotive qualification, ROHS3 compliance, and REACH unaffected status. No compliance gaps exist between the two parts.

3. Inventory Availability: The substitute part demonstrates higher current inventory (870 Pcs vs. 793 Pcs), supporting sustained procurement requirements.

4. Electrical and Mechanical Identity: All critical parameters—resistance, tolerance, power rating, temperature coefficient, operating range, package dimensions, and termination count—are identical between the main part and substitute.

For applications currently using RK73G1HTTC1502F, direct substitution with RK73G1HTTCM1502F requires no circuit redesign, PCB layout modification, or functional re-qualification. The parts are pin-compatible and functionally interchangeable.

Frequently Asked Questions (FAQ)

Q: Can RK73G1HTTCM1502F be used as a direct replacement for RK73G1HTTC1502F in existing designs?

A: Yes. The RK73G1HTTCM1502F is a direct functional equivalent. All electrical parameters (15 kOhms ±1%, 0.05W, ±50ppm/°C, -55°C ~ 155°C), mechanical specifications (0201 package, 0.60mm x 0.30mm), and compliance certifications (AEC-Q200, ROHS3) are identical. No circuit modifications or re-qualification are required.

Q: What is the difference between RK73G1HTTC1502F and RK73G1HTTCM1502F?

A: The parts are electrically and mechanically identical. The primary difference is product status: RK73G1HTTC1502F is "Not For New Designs," while RK73G1HTTCM1502F is "Active." The substitute part represents the current production equivalent within the RK73G series.

Q: Are both parts suitable for automotive applications?

A: Yes. Both the RK73G1HTTC1502F and RK73G1HTTCM1502F carry AEC-Q200 automotive qualification, confirming suitability for automotive-grade reliability requirements.

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

A: This designation indicates that while the RK73G1HTTC1502F remains available in inventory, the manufacturer has transitioned to the RK73G1HTTCM1502F as the active production part. For new designs and ongoing production, the substitute part should be specified to ensure long-term supply continuity and manufacturer support.

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

A: No. Both parts use the identical 0201 (0603 Metric) package 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 are identical.

Q: Do both parts have the same moisture sensitivity rating?

A: Yes. Both parts carry Moisture Sensitivity Level 1 (Unlimited), indicating no moisture-related storage or handling restrictions.

Q: Which part should be specified for new production orders?

A: The RK73G1HTTCM1502F should be specified for new production orders due to its "Active" product status and higher current inventory availability. This ensures sustained supply and manufacturer support.
