Substitute Part Grouping Explanation

Substitute parts for the RK73H1HTTC13R0F are qualified based on strict electrical and mechanical parameter matching:

Substitution Criteria:

• Resistance value: 13 Ohms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 0.05W / 1/20W (exact match required)
• Package: 0201 (0603 Metric) (exact match required)
• Composition: Thick Film (exact match required)
• Temperature coefficient: ±200ppm/°C (exact match required)
• Operating temperature range: -55°C ~ 155°C (exact match required)
• Automotive qualification: AEC-Q200 (exact match required)
• Moisture resistance: Present (exact match required)
• RoHS compliance: ROHS3 Compliant (exact match required)

Substitute parts are grouped into two categories:

Category 1: Manufacturer Recommended Substitute (KOA Speer Electronics)

• RK73H1HTTCM13R0F: Active product status, same manufacturer, identical electrical and mechanical specifications, represents the current production equivalent.

Category 2: Direct Cross-Reference Substitute (Alternative Manufacturer)

• AC0201FR-0713RL: YAGEO manufacturer, active product status, meets all electrical and mechanical parameter requirements, provides alternative sourcing.

Parameter Comparison

Engineering Selection Recommendations

For Legacy System Support and Replacement:

RK73H1HTTCM13R0F is the primary substitute. As the manufacturer-recommended equivalent from KOA Speer Electronics, it maintains design continuity with the original part while offering active product status. This part is suitable for direct replacement in existing designs and provides ongoing supply chain availability.

For Alternative Sourcing:

AC0201FR-0713RL from YAGEO provides a qualified cross-reference option. This part meets all electrical and mechanical specifications, maintains AEC-Q200 automotive qualification, and offers supply diversification. The part is actively produced and available in Tape & Reel packaging.

Compliance Considerations:

Both substitute parts maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity ratings, ensuring compatibility with existing assembly and storage protocols. Both are suitable for automotive applications requiring AEC-Q200 qualification.

Frequently Asked Questions (FAQ)

Q: Can RK73H1HTTCM13R0F be used as a direct replacement for RK73H1HTTC13R0F?

A: Yes. RK73H1HTTCM13R0F is the manufacturer-recommended substitute from KOA Speer Electronics. It matches all electrical parameters (13 Ohms ±1%, 0.05W, ±200ppm/°C, -55°C ~ 155°C) and mechanical specifications (0201 package, AEC-Q200, ROHS3 compliant, MSL 1). The primary difference is active product status versus the obsolete status of the original part.

Q: What is the difference between RK73H1HTTC13R0F and RK73H1HTTCM13R0F?

A: Both parts are 13 Ohm ±1% thick film resistors in 0201 packages from KOA Speer Electronics with identical electrical specifications. The main distinction is product lifecycle status: RK73H1HTTC13R0F is "Not For New Designs," while RK73H1HTTCM13R0F is "Active." The original part specifies moisture resistance; this specification is not provided for the recommended substitute.

Q: Is AC0201FR-0713RL compatible with designs using RK73H1HTTC13R0F?

A: Yes. AC0201FR-0713RL from YAGEO meets all electrical and mechanical requirements: 13 Ohms ±1%, 0.05W power rating, 0201 package, ±200ppm/°C temperature coefficient, -55°C ~ 155°C operating range, AEC-Q200 automotive qualification, ROHS3 compliance, and MSL 1 rating. It is actively produced and available in Tape & Reel packaging.

Q: Are there packaging differences between these substitutes?

A: RK73H1HTTC13R0F and AC0201FR-0713RL are both supplied in Tape & Reel (TR) packaging. RK73H1HTTCM13R0F packaging is not specified in available data. For applications requiring specific packaging formats, confirm packaging availability with the supplier.

Q: Do all three parts meet automotive standards?

A: Yes. All three parts carry AEC-Q200 automotive qualification and are suitable for automotive applications. All maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity ratings.

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

A: This designation indicates the part has been superseded in the manufacturer's product line. RK73H1HTTCM13R0F represents the current production equivalent. For new designs, use the active substitute. For legacy system support, either substitute is acceptable based on availability and sourcing requirements.
