Critical Matching Parameters:

• Resistance value: 59 kOhms
• Tolerance: ±1%
• Power rating: 0.05W (1/20W)
• Package: 0201 (0603 Metric)
• Composition: Thick Film
• 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 substitute parts listed meet these parameters without exception. Substitutes are grouped by manufacturer and product status to facilitate selection based on availability and design phase requirements.

Parameter Comparison

Engineering Selection Recommendations

For Legacy System Support: The RK73H1HTTCM5902F (KOA Speer Electronics) is the manufacturer-recommended substitute. This part maintains full electrical and mechanical equivalence to the original RK73H1HTTC5902F while holding Active product status, ensuring continued availability and manufacturing support. Both parts are from the same manufacturer and series (RK73H), providing design continuity.

For Cross-Manufacturer Substitution: The AC0201FR-0759KL (YAGEO) provides a direct equivalent alternative with Active product status. This part meets all electrical specifications, AEC-Q200 automotive qualification, moisture resistance, and RoHS compliance requirements. Cross-manufacturer substitution is electrically and mechanically valid when supply chain diversification is required.

Compliance Considerations: All three parts are ROHS3 compliant, AEC-Q200 qualified, and rated MSL 1 (Unlimited moisture sensitivity level). Selection between parts should be based on availability, supply chain strategy, and packaging requirements rather than technical performance differences.

Frequently Asked Questions (FAQ)

Q: Can RK73H1HTTCM5902F directly replace RK73H1HTTC5902F?

A: Yes. The RK73H1HTTCM5902F is the manufacturer-recommended substitute with identical electrical specifications (59 kOhms ±1%, 0.05W), package (0201), temperature range (-55°C ~ 155°C), and AEC-Q200 automotive qualification. The primary difference is product status: the original is "Not For New Designs" while the substitute is Active.

Q: Is AC0201FR-0759KL from YAGEO compatible with the original KOA part?

A: Yes. The AC0201FR-0759KL meets all critical parameters: 59 kOhms ±1%, 0.05W power rating, 0201 package, ±200ppm/°C temperature coefficient, -55°C ~ 155°C operating range, AEC-Q200 qualification, moisture resistance, and ROHS3 compliance. Cross-manufacturer substitution is valid for this application.

Q: What is the difference between RK73H1HTTC5902F and RK73H1HTTCM5902F?

A: Both parts are electrically and mechanically identical 59 kOhm ±1% 0.05W 0201 resistors from KOA Speer Electronics. The primary distinction is product lifecycle status: RK73H1HTTC5902F is classified "Not For New Designs," while RK73H1HTTCM5902F is Active. The "M" designation in the part number indicates the active variant.

Q: Are all substitute parts moisture-resistant?

A: The RK73H1HTTC5902F and AC0201FR-0759KL are both specified as moisture-resistant. The RK73H1HTTCM5902F does not list moisture resistance in its detailed description, though it maintains MSL 1 rating. For applications requiring explicit moisture resistance, verify with the manufacturer or select RK73H1HTTC5902F or AC0201FR-0759KL.

Q: Do all parts support the same temperature range?

A: Yes. All three substitute parts operate across the identical temperature range of -55°C ~ 155°C with ±200ppm/°C temperature coefficient, ensuring thermal performance equivalence.

Q: What packaging formats are available?

A: RK73H1HTTC5902F and AC0201FR-0759KL are supplied in Tape & Reel (TR) format. RK73H1HTTCM5902F packaging type is not specified in available data. Confirm packaging requirements with the supplier before ordering.
