Substitute Part Grouping Explanation

Substitute parts for the RK73H1HTTC16R2F are qualified based on strict electrical and mechanical parameter matching:

Substitution Criteria:

• Resistance value: 16.2 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 compliance: AEC-Q200 (exact match required)
• Moisture resistance: Present (exact match required)
• RoHS compliance: ROHS3 Compliant (exact match required)
• MSL rating: 1 (Unlimited) (exact match required)

Substitute parts are grouped into two categories:

Category 1: Manufacturer-Recommended Equivalent RK73H1HTTCM16R2F from KOA Speer Electronics, Inc. — Active product status, same series, identical electrical and mechanical specifications, direct replacement within the same manufacturer line.

Category 2: Cross-Manufacturer Substitute AC0201FR-0716R2L from YAGEO — Active product status, identical electrical and mechanical specifications, different manufacturer, suitable for applications requiring supply chain diversification or alternative sourcing.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Preferred): RK73H1HTTCM16R2F is the manufacturer-recommended equivalent. It maintains the same KOA Speer Electronics product line, carries Active product status, and provides identical electrical and mechanical specifications. This part is suitable for new production runs and design updates requiring the RK73H1HTTC16R2F.

For Cross-Manufacturer Substitution: AC0201FR-0716R2L from YAGEO provides a functionally equivalent alternative with Active product status. All critical electrical parameters, package dimensions, temperature performance, and automotive compliance certifications are identical. This part is suitable for applications requiring supply chain redundancy or alternative sourcing strategies.

Compliance Considerations: Both substitute parts maintain ROHS3 compliance and AEC-Q200 automotive qualification, ensuring compatibility with regulated applications and automotive supply chain requirements. MSL rating of 1 (Unlimited) on all parts eliminates moisture sensitivity constraints during storage and handling.

Frequently Asked Questions (FAQ)

Q: Can RK73H1HTTCM16R2F be used as a direct replacement for RK73H1HTTC16R2F? A: Yes. RK73H1HTTCM16R2F is the manufacturer-recommended equivalent with identical electrical specifications (16.2 Ohms ±1%, 0.05W), package format (0201), temperature performance (-55°C ~ 155°C), and automotive AEC-Q200 rating. The primary difference is Active product status versus Not For New Designs status.

Q: What is the difference between RK73H1HTTC16R2F and RK73H1HTTCM16R2F? A: Both parts share identical resistance, tolerance, power rating, package, composition, temperature coefficient, operating temperature range, and AEC-Q200 compliance. The main distinction is product lifecycle status: RK73H1HTTC16R2F is Not For New Designs, while RK73H1HTTCM16R2F is Active. The "M" designation in the part number indicates the active variant.

Q: Is AC0201FR-0716R2L from YAGEO compatible with designs using RK73H1HTTC16R2F? A: Yes. AC0201FR-0716R2L meets all electrical and mechanical requirements: 16.2 Ohms ±1%, 0.05W power rating, 0201 package, ±200ppm/°C temperature coefficient, -55°C ~ 155°C operating range, AEC-Q200 automotive rating, and ROHS3 compliance. It is suitable for applications requiring cross-manufacturer sourcing.

Q: Are there any differences in moisture resistance between the substitute parts? A: RK73H1HTTC16R2F and AC0201FR-0716R2L both specify moisture-resistant construction. RK73H1HTTCM16R2F does not explicitly specify moisture resistance in the provided data. All three parts carry MSL rating 1 (Unlimited), indicating no moisture sensitivity constraints during standard handling and storage.

Q: Can these parts be used interchangeably in automotive applications? A: Yes. All three parts carry AEC-Q200 automotive qualification and ROHS3 compliance, meeting automotive supply chain and regulatory requirements. Electrical and thermal specifications are identical across all parts.
