Key Parameters

Substitute Part Grouping Explanation

Substitution of the RK73H1HTTC2153F is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Resistance value: 215 kOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 0.05W / 1/20W (exact match required)
• Temperature coefficient: ±200ppm/°C (exact match required)
• Operating temperature range: -55°C ~ 155°C (exact match required)

Mechanical Parameters:

• Package type: 0201 (0603 Metric) (exact match required)
• Physical dimensions: 0.024" L x 0.012" W (0.60mm x 0.30mm) (exact match required)
• Height seated (max): 0.010" (0.26mm) (exact match required)

Compliance & Certification:

• Automotive qualification: AEC-Q200 (required for automotive applications)
• RoHS compliance: ROHS3 Compliant (required)
• Moisture sensitivity: MSL 1 (Unlimited) (required)

Substitute parts must match all electrical and mechanical parameters without exception. Composition (thick film) and moisture resistance are functional requirements that must be maintained.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: RK73H1HTTCM2153F (KOA Speer Electronics)

The RK73H1HTTCM2153F is the manufacturer-recommended equivalent from KOA Speer Electronics. This part maintains active product status and provides direct electrical and mechanical compatibility with the original RK73H1HTTC2153F. Both parts share identical resistance, tolerance, power rating, temperature coefficient, and operating temperature range. The primary distinction is that the substitute part is currently in active production, whereas the original part is designated "Not For New Designs." The RK73H1HTTCM2153F carries full AEC-Q200 automotive qualification and ROHS3 compliance. Note that moisture resistance is not explicitly specified for this variant, though both parts maintain MSL 1 (Unlimited) rating.

Secondary Substitute: AC0201FR-07215KL (YAGEO)

The AC0201FR-07215KL from YAGEO provides cross-manufacturer equivalence with identical electrical specifications and package dimensions. This part is actively produced and carries AEC-Q200 automotive qualification with explicit moisture-resistant construction. All critical parameters—resistance, tolerance, power rating, temperature coefficient, and operating temperature range—match the original part exactly. The AC0201FR-07215KL is supplied in Tape & Reel packaging and maintains ROHS3 compliance and MSL 1 (Unlimited) rating.

Selection Basis:

Both substitute parts satisfy all mandatory electrical, mechanical, and compliance requirements. Selection between them should be based on:

• Supplier availability and lead time
• Packaging requirements (both available in Tape & Reel format)
• Existing supply chain relationships
• Cost considerations
• Moisture resistance criticality in the application (AC0201FR-07215KL explicitly specifies this feature)

Frequently Asked Questions (FAQ)

Q: Can RK73H1HTTCM2153F be used as a direct replacement for RK73H1HTTC2153F?

A: Yes. The RK73H1HTTCM2153F is the manufacturer-recommended equivalent. Both parts share identical electrical parameters (215 kOhms ±1%, 0.05W, ±200ppm/°C, -55°C ~ 155°C), mechanical specifications (0201 package, 0.60mm x 0.30mm), and compliance ratings (AEC-Q200, ROHS3, MSL 1). The primary difference is product status: the substitute is actively produced while the original is not recommended for new designs.

Q: What is the difference between RK73H1HTTC2153F and RK73H1HTTCM2153F?

A: The primary difference is the inclusion of "M" in the part number designation (RK73H1HTTCM2153F), which indicates an active production variant. Both parts are electrically and mechanically identical. The original part is classified as "Not For New Designs," while the substitute is in active production status. Moisture resistance is explicitly specified for the original part but not stated for the substitute variant.

Q: Can AC0201FR-07215KL from YAGEO replace the KOA part?

A: Yes. The AC0201FR-07215KL meets all electrical and mechanical requirements. It provides identical resistance (215 kOhms ±1%), power rating (0.05W), temperature coefficient (±200ppm/°C), operating range (-55°C ~ 155°C), and package specifications (0201, 0.60mm x 0.30mm). Both parts carry AEC-Q200 automotive qualification and ROHS3 compliance. The YAGEO part explicitly specifies moisture-resistant construction.

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

A: The RK73H1HTTC2153F and AC0201FR-07215KL are both supplied in Tape & Reel (TR) format. The RK73H1HTTCM2153F packaging format is not specified in available documentation. Confirm packaging requirements with your supplier before procurement.

Q: Do all substitute parts maintain AEC-Q200 automotive qualification?

A: Yes. Both RK73H1HTTCM2153F and AC0201FR-07215KL carry full AEC-Q200 automotive qualification, matching the original part's certification level.

Q: What is the significance of MSL 1 (Unlimited) rating?

A: MSL 1 (Unlimited) indicates the component has unlimited shelf life and does not require special moisture-controlled storage or handling. All three parts—the original and both substitutes—carry this rating, eliminating moisture sensitivity as a constraint in component storage and assembly processes.

Q: Can these parts be used interchangeably in production?

A: Yes, provided all electrical, mechanical, and compliance requirements are met. Both substitute parts satisfy these criteria. However, confirm with your quality and procurement departments regarding any internal part qualification requirements or supply chain preferences before implementing substitution in production.
