Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: RK73H1HTTCM1963F (KOA Speer Electronics)

This part is the manufacturer-recommended substitute from KOA Speer Electronics. It maintains all electrical and mechanical specifications identical to the original RK73H1HTTC1963F. The primary distinction is active product status versus the original's "Not For New Designs" classification. This part is suitable for direct replacement in legacy applications and new designs requiring the same electrical performance. Note: This variant does not specify moisture-resistant construction in the provided data, though it retains AEC-Q200 automotive qualification and MSL 1 rating.

Secondary Substitute: AC0201FR-07196KL (YAGEO)

This YAGEO part provides cross-manufacturer equivalence with identical electrical specifications and explicit moisture-resistant construction. It carries active product status and full AEC-Q200 automotive qualification. This option is suitable where multi-source component strategy or YAGEO supply chain preference is required. The part maintains all critical parameters for direct functional substitution.

Selection Basis:

• All substitutes match the 196 kOhms ±1% resistance specification
• All maintain 0.05W power rating and 0201 package dimensions
• All comply with AEC-Q200 automotive standards
• All achieve ROHS3 compliance and MSL 1 moisture sensitivity rating
• All operate across the -55°C ~ 155°C temperature range
• All feature ±200ppm/°C temperature coefficient

Selection between substitutes should be based on supply availability, manufacturing source preference, and specific moisture-resistant construction requirements for the application.

Frequently Asked Questions (FAQ)

Q: Can RK73H1HTTCM1963F directly replace RK73H1HTTC1963F?

A: Yes. Both parts are manufactured by KOA Speer Electronics with identical electrical specifications (196 kOhms ±1%, 0.05W, ±200ppm/°C) and physical dimensions (0201 package). The primary difference is product status: the original is "Not For New Designs" while the substitute is "Active." All compliance ratings (AEC-Q200, ROHS3, MSL 1) are maintained.

Q: Is AC0201FR-07196KL from YAGEO compatible with the original KOA part?

A: Yes. The YAGEO AC0201FR-07196KL meets all electrical and mechanical specifications of the RK73H1HTTC1963F. Both parts are 196 kOhms ±1%, 0.05W, 0201 package, AEC-Q200 qualified, and ROHS3 compliant. This represents a cross-manufacturer equivalent suitable for applications where YAGEO sourcing is preferred or required.

Q: What are the critical parameters for substitution?

A: Substitution validity depends on matching: resistance value (196 kOhms), tolerance (±1%), power rating (0.05W), package type (0201), composition (thick film), temperature coefficient (±200ppm/°C), operating range (-55°C ~ 155°C), and automotive qualification (AEC-Q200). All listed substitutes maintain these parameters.

Q: Does the absence of "moisture resistant" notation on RK73H1HTTCM1963F affect compatibility?

A: The RK73H1HTTCM1963F maintains MSL 1 (Unlimited) rating and AEC-Q200 qualification identical to the original. While moisture-resistant construction is not explicitly stated in the provided data for this variant, the MSL 1 classification indicates suitability for unlimited shelf life without baking requirements. For applications requiring explicit moisture-resistant construction, AC0201FR-07196KL specifies this feature.

Q: Are all substitutes suitable for automotive applications?

A: Yes. All listed substitutes carry AEC-Q200 automotive qualification, matching the original part's automotive-grade specification. This rating applies to RK73H1HTTCM1963F and AC0201FR-07196KL.

Q: What is the difference between the two KOA variants?

A: RK73H1HTTC1963F (original) and RK73H1HTTCM1963F (substitute) differ in product status and packaging specification. The original is "Not For New Designs" with Tape & Reel packaging noted; the substitute is "Active" with packaging not specified in the provided data. Electrical specifications and compliance ratings are identical.
