Parameter Comparison

Engineering Selection Recommendations

For Continued Production Support:

The RK73H1HTTCM8252F is the manufacturer-recommended substitute from KOA Speer Electronics, Inc. This part maintains identical electrical specifications and automotive AEC-Q200 certification while carrying an Active product status. Selection of this part ensures continuity within the same manufacturer's product line and supply chain stability.

For Cross-Manufacturer Substitution:

The AC0201FR-0782K5L from YAGEO provides a qualified alternative with Active product status. This part meets all critical electrical and mechanical parameters, including AEC-Q200 automotive rating, moisture resistance, and ROHS3 compliance. Cross-manufacturer substitution is appropriate when supply constraints or cost considerations require alternative sourcing while maintaining full electrical and environmental specification equivalence.

Compliance Considerations:

Both substitute parts maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating, ensuring compatibility with automotive assembly processes and long-term storage requirements. The operating temperature range of -55°C ~ 155°C is preserved across all options, supporting the full range of automotive thermal environments.

Frequently Asked Questions (FAQ)

Q: Can RK73H1HTTCM8252F be used as a direct replacement for RK73H1HTTC8252F?

A: Yes. The RK73H1HTTCM8252F is the manufacturer-recommended substitute from KOA Speer Electronics. It provides identical electrical specifications (82.5 kOhms ±1%, 0.05W), package format (0201), and automotive AEC-Q200 certification. The primary difference is product status: RK73H1HTTCM8252F is Active, while the original part is Not For New Designs.

Q: What is the difference between RK73H1HTTC8252F and RK73H1HTTCM8252F?

A: Both parts are manufactured by KOA Speer Electronics with identical electrical and mechanical specifications. The suffix variation indicates a product line update. RK73H1HTTCM8252F represents the current active production version, while RK73H1HTTC8252F has been transitioned to end-of-life status.

Q: Is AC0201FR-0782K5L from YAGEO fully compatible with the original KOA part?

A: Yes. The AC0201FR-0782K5L meets all critical parameters: 82.5 kOhms ±1% resistance, 0.05W power rating, 0201 package, thick film composition, ±200ppm/°C temperature coefficient, -55°C ~ 155°C operating range, AEC-Q200 automotive rating, moisture resistance, ROHS3 compliance, and MSL 1 rating. Electrical and mechanical compatibility is complete.

Q: Are there any packaging differences between these substitutes?

A: The RK73H1HTTC8252F and AC0201FR-0782K5L are both supplied in Tape & Reel (TR) format. The RK73H1HTTCM8252F packaging specification is not provided in available documentation. Confirm packaging requirements with your supplier before procurement.

Q: Can these parts be used interchangeably in automotive applications?

A: Yes. All three parts carry AEC-Q200 automotive qualification and are rated for the same operating temperature range (-55°C ~ 155°C). They are suitable for automotive circuit applications requiring 82.5 kOhms ±1% resistance with 0.05W power dissipation in 0201 package format.

Q: What is the significance of the "Not For New Designs" status?

A: This designation indicates that KOA Speer Electronics has discontinued active development and new design support for the RK73H1HTTC8252F. Existing inventory remains available for production support and field repairs. For new designs, KOA recommends transitioning to RK73H1HTTCM8252F or equivalent alternatives.

Q: Are moisture-resistant properties maintained across all substitutes?

A: The RK73H1HTTC8252F and AC0201FR-0782K5L explicitly specify moisture-resistant construction. The RK73H1HTTCM8252F does not include moisture resistance in its specification documentation. If moisture resistance is a critical requirement, confirm this specification with the supplier before selection.
