Substitute Part Grouping Explanation

Substitute parts for the RK73H1HTTC1692F are qualified based on strict electrical and mechanical parameter matching:

Substitution Criteria:

• Resistance value: 16.9 kOhms (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: Yes (exact match required)
• RoHS compliance: ROHS3 Compliant (exact match required)
• MSL rating: 1 (Unlimited) (exact match required)

All identified substitute parts meet these criteria and are therefore electrically and mechanically interchangeable with the main part in applications requiring these specifications.

Parameter Comparison

Engineering Selection Recommendations

RK73H1HTTCM1692F (KOA Speer Electronics, Inc.): This part is the manufacturer-recommended substitute for the RK73H1HTTC1692F. Both are KOA products with identical electrical and mechanical specifications. The primary distinction is product status: RK73H1HTTCM1692F is classified as Active, whereas the original part is Not For New Designs. This substitute maintains full compatibility with existing designs and is suitable for ongoing production and procurement.

AC0201FR-0716K9L (YAGEO): This part provides cross-manufacturer substitution with identical electrical and mechanical parameters. YAGEO's AC series thick film resistor meets all specified requirements including AEC-Q200 automotive qualification, RoHS3 compliance, and MSL 1 rating. This substitute is classified as Active and is available in Tape & Reel packaging, supporting high-volume manufacturing requirements.

Both substitute parts are qualified for direct replacement in applications where the RK73H1HTTC1692F was originally specified, with no circuit redesign or validation required.

Frequently Asked Questions (FAQ)

Q: Can RK73H1HTTCM1692F be used as a direct replacement for RK73H1HTTC1692F?

A: Yes. Both parts are manufactured by KOA Speer Electronics and share identical electrical specifications (16.9 kOhms ±1%, 0.05W), mechanical dimensions (0201 package), temperature characteristics (±200ppm/°C, -55°C to 155°C), and automotive qualifications (AEC-Q200). The primary difference is product lifecycle status; RK73H1HTTCM1692F is Active while the original is Not For New Designs.

Q: Is AC0201FR-0716K9L from YAGEO compatible with the original KOA part?

A: Yes. AC0201FR-0716K9L meets all electrical and mechanical requirements: 16.9 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 packaging options are available for these substitutes?

A: RK73H1HTTC1692F and AC0201FR-0716K9L are both supplied in Tape & Reel (TR) packaging. RK73H1HTTCM1692F packaging type is not specified in available documentation. Confirm packaging requirements with your procurement department before finalizing part selection.

Q: Are all three parts suitable for automotive applications?

A: Yes. All three parts carry AEC-Q200 qualification, which certifies suitability for automotive applications including temperature cycling, moisture exposure, and reliability requirements specific to automotive environments.

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

A: MSL 1 (Unlimited) indicates the component has no moisture sensitivity limitations. These parts do not require special moisture-controlled storage or handling procedures and can be stored under standard industrial conditions indefinitely without degradation.

Q: Can these parts be used interchangeably in existing PCB designs?

A: Yes. All three parts are identical in physical dimensions (0.024" L x 0.012" W, 0.60mm x 0.30mm) and maximum seated height (0.010" / 0.26mm), with two terminations in 0201 package configuration. No PCB layout modifications are required for substitution.
