Key Parameters

Substitute Part Grouping Explanation

Substitution of the RK73H1HTTC1104F is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Resistance value: 1.1 MOhms (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 / Case: 0201 (0603 Metric) (exact match required)
• Composition: Thick Film (exact match required)

Compliance & Certification:

• AEC-Q200 automotive qualification (required for automotive applications)
• RoHS3 compliance (required for regulatory adherence)
• Moisture Sensitivity Level MSL 1 (required for unlimited shelf life)

Substitute parts must satisfy all parameters listed above. No deviations in electrical specifications, package dimensions, or compliance certifications are permitted for direct substitution.

Parameter Comparison

Engineering Selection Recommendations

The RK73H1HTTCM1104F is the direct equivalent substitute for the RK73H1HTTC1104F. Both components are manufactured by KOA Speer Electronics, Inc. within the RK73H series and share identical electrical specifications, mechanical dimensions, and compliance certifications.

The primary distinction between these parts is product lifecycle status: the RK73H1HTTC1104F is designated "Not For New Designs," while the RK73H1HTTCM1104F maintains "Active" status. This indicates that KOA Speer Electronics continues to manufacture and support the RK73H1HTTCM1104F for ongoing production requirements.

For applications requiring AEC-Q200 automotive qualification, RoHS3 compliance, and unlimited moisture sensitivity rating, the RK73H1HTTCM1104F provides full functional and mechanical compatibility with existing designs using the RK73H1HTTC1104F. The substitute part satisfies all electrical performance criteria, thermal operating range, and regulatory requirements without design modification.

Frequently Asked Questions (FAQ)

Q: Can the RK73H1HTTCM1104F be used as a direct replacement for the RK73H1HTTC1104F in existing designs?

A: Yes. The RK73H1HTTCM1104F is electrically and mechanically equivalent to the RK73H1HTTC1104F. Both components feature identical resistance (1.1 MOhms), tolerance (±1%), power rating (0.05W), package dimensions (0201 / 0603 metric), and compliance certifications (AEC-Q200, RoHS3, MSL 1). No circuit modifications or PCB layout changes are required.

Q: Why is the RK73H1HTTC1104F marked "Not For New Designs"?

A: This designation indicates that KOA Speer Electronics has transitioned the RK73H1HTTC1104F to end-of-life status and is no longer recommending it for new product development. The RK73H1HTTCM1104F represents the current active equivalent within the RK73H series portfolio.

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

A: The RK73H1HTTC1104F is specified as Tape & Reel (TR) packaging. The RK73H1HTTCM1104F packaging specification is not provided in the available data. Contact the manufacturer or authorized distributor to confirm packaging format compatibility with your assembly equipment and procurement requirements.

Q: Do both parts meet automotive qualification standards?

A: Yes. Both the RK73H1HTTC1104F and RK73H1HTTCM1104F carry AEC-Q200 automotive qualification ratings and are suitable for automotive applications requiring this certification level.

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

A: MSL 1 indicates that these components have unlimited shelf life and do not require special moisture-controlled storage or baking procedures prior to assembly. This simplifies inventory management and reduces handling complexity compared to higher MSL-rated components.

Q: Are both parts RoHS3 compliant?

A: Yes. Both the RK73H1HTTC1104F and RK73H1HTTCM1104F are ROHS3 compliant and meet current regulatory requirements for restricted substance elimination in electronic components.
