Parameter Comparison

Engineering Selection Recommendations

Primary Substitute (Manufacturer Recommended): RK73H1HTTCM30R1F from KOA Speer Electronics, Inc. is the manufacturer-recommended upgrade path. This part maintains identical electrical and mechanical specifications while carrying an Active product status, ensuring long-term availability and supply chain continuity. Selection of this part is appropriate for new production runs and design revisions.

Alternative Substitute (Cross-Manufacturer): AC0201FR-0730R1L from YAGEO provides equivalent functionality with Active product status from an alternative qualified manufacturer. This part meets all electrical, mechanical, and compliance requirements (AEC-Q200, ROHS3, MSL 1) and is suitable for applications requiring multi-source qualification or where YAGEO supply chain advantages apply.

Legacy Part Retention: The RK73H1HTTC30R1F remains functionally valid for existing designs and ongoing production support of established products. However, transition to an Active substitute part is recommended for new design initiatives to ensure extended product lifecycle support.

Frequently Asked Questions (FAQ)

Q: Can RK73H1HTTCM30R1F directly replace RK73H1HTTC30R1F in existing designs?

A: Yes. Both parts share identical electrical specifications (30.1 Ohms ±1%, 0.05W), mechanical dimensions (0201 package), temperature characteristics (±200ppm/°C, -55°C ~ 155°C), and automotive qualifications (AEC-Q200). Direct substitution is functionally equivalent with no circuit modifications required.

Q: Is AC0201FR-0730R1L from YAGEO compatible with designs specified for KOA parts?

A: Yes. The AC0201FR-0730R1L meets all critical parameters: 30.1 Ohms ±1%, 0.05W power rating, 0201 package, ±200ppm/°C temperature coefficient, -55°C ~ 155°C operating range, AEC-Q200 automotive qualification, and ROHS3 compliance. Cross-manufacturer substitution is electrically and mechanically valid.

Q: What is the difference between RK73H1HTTC30R1F and RK73H1HTTCM30R1F?

A: The primary difference is product status. RK73H1HTTC30R1F is marked "Not For New Designs," while RK73H1HTTCM30R1F is Active. All electrical, mechanical, and compliance parameters are identical. The "M" designation in the part number indicates the active production variant.

Q: Are all three parts suitable for automotive applications?

A: Yes. All three parts carry AEC-Q200 qualification, moisture-resistant construction, and operate across the -55°C ~ 155°C automotive temperature range. All are compliant with ROHS3 and carry MSL 1 (Unlimited) moisture sensitivity ratings.

Q: What packaging options are available for these substitutes?

A: RK73H1HTTC30R1F and AC0201FR-0730R1L are supplied in Tape & Reel (TR) packaging. RK73H1HTTCM30R1F packaging specification is not provided in available documentation.

Q: Can these parts be used interchangeably in high-reliability applications?

A: Yes. All three parts meet AEC-Q200 automotive qualification standards and carry identical reliability ratings. Selection between them should be based on product status (Active vs. Not For New Designs) and supply chain requirements rather than reliability considerations.
