Substitute Part Grouping Explanation

Substitute parts for the RK73H1HTTC4873F are qualified based on the following electrical and mechanical parameters:

Substitution Criteria:

• Resistance value: 487 kOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 0.05W / 1/20W (exact match required)
• Package: 0201 (0603 Metric) (exact match required)
• Composition: Thick Film (exact match required)
• Temperature coefficient: ±200ppm/°C (exact match required)
• Operating temperature range: -55°C ~ 155°C (exact match required)
• Automotive qualification: AEC-Q200 (exact match required)
• RoHS compliance: ROHS3 Compliant (exact match required)
• Moisture sensitivity: MSL 1 (exact match required)

All identified substitute parts meet these criteria and are therefore electrically and mechanically interchangeable with the main part in applications requiring these specifications.

Engineering Selection Recommendations

RK73H1HTTCM4873F (KOA Speer Electronics, Inc.) - Primary Equivalent:

This part is the direct successor within the KOA product line. It maintains identical electrical specifications and package configuration while carrying an Active product status. This part is recommended for new designs and ongoing production requiring continuity with the original KOA manufacturer. The component is ROHS3 compliant and carries MSL 1 rating, ensuring compatibility with standard manufacturing processes.

AC0201FR-07487KL (YAGEO) - Cross-Manufacturer Substitute:

This YAGEO component provides full electrical and mechanical equivalence with the original part. It is currently in Active production status with confirmed inventory availability. The AC0201FR-07487KL includes moisture-resistant construction and meets all automotive AEC-Q200 requirements. This part is suitable for applications where multi-source qualification is required or where YAGEO supply chain access is preferred.

Both substitute parts are qualified for direct replacement in automotive and industrial applications requiring 487 kOhm ±1% resistors with AEC-Q200 certification in 0201 package format.

Frequently Asked Questions (FAQ)

Q: Can RK73H1HTTCM4873F be used as a direct replacement for RK73H1HTTC4873F?

A: Yes. Both parts are manufactured by KOA Speer Electronics, Inc., and share identical electrical parameters (487 kOhms ±1%, 0.05W, ±200ppm/°C, -55°C ~ 155°C operating range) and package specifications (0201 / 0603 Metric). The primary difference is product status: RK73H1HTTCM4873F is Active, while the original is Not For New Designs. Both are ROHS3 compliant with MSL 1 rating.

Q: What is the difference between RK73H1HTTC4873F and RK73H1HTTCM4873F?

A: The suffix "M" in RK73H1HTTCM4873F indicates a manufacturing revision or product line update within KOA's RK73H series. Electrical and mechanical specifications remain identical. The main practical difference is availability and production status: RK73H1HTTCM4873F is in active production with higher inventory levels (1048 Pcs vs. 792 Pcs).

Q: Is AC0201FR-07487KL compatible with designs originally specified for RK73H1HTTC4873F?

A: Yes. AC0201FR-07487KL meets all critical substitution parameters: 487 kOhms ±1% resistance, 0.05W power rating, 0201 package, thick film composition, ±200ppm/°C temperature coefficient, -55°C ~ 155°C operating range, AEC-Q200 automotive qualification, ROHS3 compliance, and MSL 1 rating. This YAGEO part is suitable for direct replacement in automotive and industrial applications.

Q: Are there any packaging differences between these substitute parts?

A: RK73H1HTTC4873F and AC0201FR-07487KL are both supplied in Tape & Reel (TR) packaging. RK73H1HTTCM4873F packaging type is not specified in available documentation. All three parts use identical 0201 (0603 Metric) case format with dimensions of 0.024" L x 0.012" W (0.60mm x 0.30mm) and maximum seated height of 0.010" (0.26mm).

Q: Do all substitute parts include moisture-resistant construction?

A: RK73H1HTTC4873F and AC0201FR-07487KL both specify moisture-resistant thick film construction. RK73H1HTTCM4873F does not explicitly list moisture resistance in its specification, though it maintains the same AEC-Q200 automotive qualification and MSL 1 rating. For applications requiring confirmed moisture resistance, AC0201FR-07487KL or the original RK73H1HTTC4873F are preferred.

Q: What compliance certifications apply to all substitute parts?

A: All three parts are ROHS3 compliant, REACH unaffected, and carry ECCN EAR99 classification. All maintain MSL 1 (Unlimited) moisture sensitivity level, indicating no special moisture control requirements during storage or handling. All are rated for AEC-Q200 automotive applications with operating temperature range of -55°C ~ 155°C.
