Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RK73H1HTTC5361F are qualified based on the following criteria:

Electrical Parameters: Resistance value (5.36 kOhms), tolerance (±1%), and power rating (0.05W) must be identical.

Mechanical Parameters: Package type (0201 / 0603 Metric), physical dimensions (0.024" L x 0.012" W / 0.60mm x 0.30mm), and seated height (0.010" / 0.26mm maximum) must match exactly.

Composition & Performance: Thick film construction, temperature coefficient (±200ppm/°C), and operating temperature range (-55°C ~ 155°C) must be equivalent.

Compliance & Ratings: AEC-Q200 automotive qualification, moisture resistance, RoHS3 compliance, and MSL 1 classification are required for substitution eligibility.

Packaging Format: Tape & Reel (TR) packaging is preferred for production environments but does not restrict substitution if electrical and mechanical specifications are identical.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection: RK73H1HTTC5361F remains the primary choice as the original specified part number with highest inventory availability (1833 units) and confirmed moisture-resistant construction.

Manufacturer-Recommended Substitute: RK73H1HTTCM5361F is the KOA Speer Electronics manufacturer-recommended alternative. This part shares identical electrical and mechanical specifications with the main part. However, moisture resistance is not explicitly listed in the provided specifications for this variant, which may be a consideration for moisture-critical applications. Inventory is available at 718 units.

Cross-Manufacturer Substitute: AC0201FR-075K36L from YAGEO meets all electrical, mechanical, and compliance requirements. This part includes moisture-resistant construction and maintains AEC-Q200 automotive qualification. Inventory availability is 1124 units. This substitute is suitable for applications where cross-manufacturer sourcing is acceptable and provides supply chain diversification.

All three parts maintain ROHS3 compliance, MSL 1 classification, and identical operating temperature ranges, making them functionally interchangeable within the specified parameters.

Frequently Asked Questions (FAQ)

Q: Can RK73H1HTTCM5361F be used as a direct replacement for RK73H1HTTC5361F?

A: RK73H1HTTCM5361F is the manufacturer-recommended substitute and shares identical electrical specifications (5.36 kOhms ±1%, 0.05W), mechanical dimensions (0201 package), temperature coefficient (±200ppm/°C), and AEC-Q200 rating. The primary difference is that moisture resistance is not specified for the HTTCM variant. For applications requiring moisture resistance, verify with KOA Speer Electronics or use AC0201FR-075K36L.

Q: Is AC0201FR-075K36L from YAGEO compatible with the original KOA part?

A: Yes. AC0201FR-075K36L meets all specified electrical parameters (5.36 kOhms ±1%, 0.05W), mechanical requirements (0201 package, identical dimensions), and compliance standards (AEC-Q200, RoHS3, MSL 1). Moisture-resistant construction is confirmed. This part is suitable for direct substitution in automotive applications.

Q: What are the critical parameters for substitution?

A: Substitution eligibility is determined by: (1) Resistance value and tolerance (5.36 kOhms ±1%), (2) Power rating (0.05W), (3) Package type and dimensions (0201 / 0603 Metric), (4) Composition (thick film), (5) Temperature coefficient (±200ppm/°C), (6) Operating temperature range (-55°C ~ 155°C), and (7) AEC-Q200 automotive qualification. All three listed parts meet these criteria.

Q: Does packaging format affect substitution?

A: Tape & Reel (TR) packaging is the standard format for production environments. All listed parts support TR packaging. Packaging format does not restrict electrical or mechanical substitution but may affect procurement logistics and handling procedures.

Q: Are there inventory considerations for part selection?

A: Current inventory levels are: RK73H1HTTC5361F (1833 units), AC0201FR-075K36L (1124 units), and RK73H1HTTCM5361F (718 units). For high-volume production, RK73H1HTTC5361F offers the highest availability. For supply chain resilience, AC0201FR-075K36L provides cross-manufacturer sourcing with adequate stock levels.

Q: What is the significance of MSL 1 classification?

A: MSL 1 (Moisture Sensitivity Level 1) indicates unlimited shelf life without moisture control requirements. All three parts carry MSL 1 classification, eliminating moisture-related storage constraints and simplifying inventory management.
