• Temperature coefficient: ±200ppm/°C
• Operating temperature range: -55°C ~ 155°C
• Automotive qualification: AEC-Q200
• Moisture resistance: Required
• RoHS compliance: ROHS3
• Moisture sensitivity: MSL 1

All identified substitute parts meet these criteria without exception. Substitutes are grouped by manufacturer and product status to facilitate sourcing decisions.

Parameter Comparison

Engineering Selection Recommendations

RK73H1HTTCM9103F (KOA Speer Electronics, Inc.): This part is the manufacturer-recommended substitute from KOA. It maintains identical electrical and mechanical specifications to the RK73H1HTTC9103F while carrying Active product status. Selection of this part ensures continuity with the original manufacturer's design intent and maintains supply chain consistency within the KOA RK73H series. Current inventory: 1,006 pieces.

AC0201FR-07910KL (YAGEO): This part provides cross-manufacturer equivalence with identical electrical and mechanical parameters. YAGEO AC series thick film resistors meet all automotive and compliance requirements specified for the original part. This option expands sourcing flexibility and may provide alternative lead times or pricing. Current inventory: 897 pieces.

Both substitute parts carry Active product status, ensuring long-term availability for new production and field service applications.

Frequently Asked Questions (FAQ)

Q: Can RK73H1HTTCM9103F be used as a direct replacement for RK73H1HTTC9103F? A: Yes. Both parts are identical in electrical specifications (910 kOhms ±1%, 0.05W), mechanical dimensions (0201 package), temperature performance (±200ppm/°C, -55°C to 155°C), and automotive qualifications (AEC-Q200). The primary difference is product status; RK73H1HTTCM9103F is Active while the original is Not For New Designs.

Q: Is AC0201FR-07910KL compatible with designs specified for RK73H1HTTC9103F? A: Yes. AC0201FR-07910KL meets all critical parameters: 910 kOhms ±1%, 0.05W power rating, 0201 package, thick film composition, ±200ppm/°C temperature coefficient, -55°C to 155°C operating range, AEC-Q200 automotive rating, and ROHS3 compliance. Cross-manufacturer substitution is valid based on parameter equivalence.

Q: What is the significance of "Not For New Designs" status? A: This designation indicates the RK73H1HTTC9103F has been superseded in the manufacturer's product line. It remains available for existing design support and field service but should not be selected for new development. Both substitute parts carry Active status, making them appropriate for ongoing and new applications.

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 automotive temperature range (-55°C to 155°C). All are ROHS3 compliant and carry MSL 1 rating.

Q: Does package size differ between these parts? A: No. All three parts use the 0201 package (0603 metric), with identical dimensions: 0.024" L x 0.012" W (0.60mm x 0.30mm) and maximum seated height of 0.010" (0.26mm).
