Parameter Comparison

Engineering Selection Recommendations

RK73H1HTTCM6981F (KOA Speer Electronics, Inc.)

This part is the manufacturer-recommended substitute from KOA Speer Electronics. It maintains identical electrical specifications and package format as the main part. The primary distinction is active product status versus the obsolete designation of RK73H1HTTC6981F. However, this variant does not include moisture-resistant construction, which is present in the original part. Selection of this substitute should account for moisture exposure requirements in the target application.

AC0201FR-076K98L (YAGEO)

This part is a direct cross-reference substitute from YAGEO, an alternative manufacturer. It provides complete electrical and mechanical equivalence with the main part, including moisture-resistant thick film construction and AEC-Q200 automotive rating. The AC0201FR-076K98L carries active product status and is suitable for new production and field replacement applications. All compliance certifications (ROHS3, REACH Unaffected, MSL 1) align with the original specification.

Both substitute parts satisfy the core substitution criteria: identical resistance, tolerance, power rating, package format, temperature coefficient, operating temperature range, and automotive certification. Selection between them depends on moisture-resistant construction requirements and supply chain considerations.

Frequently Asked Questions (FAQ)

Q: Can RK73H1HTTCM6981F be used as a direct replacement for RK73H1HTTC6981F?

A: RK73H1HTTCM6981F provides electrical and mechanical equivalence with identical resistance (6.98 kOhms ±1%), power rating (0.05W), package format (0201), temperature coefficient (±200ppm/°C), and AEC-Q200 automotive rating. The key difference is the absence of moisture-resistant construction in the substitute. Applications requiring moisture resistance should use AC0201FR-076K98L instead.

Q: What is the difference between RK73H1HTTC6981F and AC0201FR-076K98L?

A: Both parts are electrically and mechanically equivalent with identical specifications across all critical parameters: 6.98 kOhms ±1%, 0.05W power rating, 0201 package, ±200ppm/°C temperature coefficient, -55°C to 155°C operating range, and AEC-Q200 rating. The primary difference is manufacturer: KOA Speer Electronics versus YAGEO. Both include moisture-resistant construction and carry active product status. Selection may be based on supply availability and procurement preferences.

Q: Are these substitutes suitable for automotive applications?

A: Yes. All substitute parts carry AEC-Q200 automotive qualification, matching the original part specification. They are rated for automotive-grade reliability and environmental stress screening requirements.

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

A: This designation indicates the RK73H1HTTC6981F is obsolete or in end-of-life phase. Substitute parts with active product status (RK73H1HTTCM6981F and AC0201FR-076K98L) are recommended for new designs and ongoing production to ensure long-term supply continuity.

Q: Do all substitute parts meet RoHS and REACH compliance?

A: Yes. All substitute parts are ROHS3 Compliant and REACH Unaffected, matching the environmental compliance profile of the original part.

Q: What does MSL 1 (Unlimited) mean for moisture sensitivity?

A: MSL 1 indicates the component has unlimited shelf life under standard storage conditions without requiring special moisture-control packaging or baking procedures prior to assembly. All listed parts maintain this MSL 1 rating.
