Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RK73G1HTTC1004F is determined by strict equivalence across the following critical parameters:

• Resistance Value: 1 MOhms (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: ±50ppm/°C (exact match required)
• Operating Temperature: -55°C ~ 155°C (exact match required)
• Automotive Compliance: AEC-Q200 (exact match required)
• RoHS Compliance: ROHS3 Compliant (exact match required)

Substitute parts must maintain identical electrical performance, thermal characteristics, and regulatory compliance. Deviations in any parameter disqualify a part from substitution consideration.

Parameter Comparison

Engineering Selection Recommendations

The RK73G1HTTCM1004F serves as the direct equivalent substitute for RK73G1HTTC1004F. Both components are manufactured by KOA Speer Electronics within the RK73G series and maintain identical electrical, thermal, and mechanical specifications. The primary distinction is product status: the original part is designated "Not For New Designs," while the substitute is classified as "Active," indicating current production and ongoing manufacturer support.

For applications currently using RK73G1HTTC1004F, transition to RK73G1HTTCM1004F is supported by:

• Identical resistance value, tolerance, and power rating
• Matching package dimensions and termination configuration
• Equivalent temperature coefficient and operating range
• Maintained AEC-Q200 automotive qualification
• Consistent RoHS3 compliance and MSL rating
• Same manufacturer and product series

No circuit redesign or board layout modification is required for this substitution.

Frequently Asked Questions (FAQ)

Q: Can RK73G1HTTCM1004F be used as a direct replacement for RK73G1HTTC1004F?

A: Yes. Both parts are electrically and mechanically identical. The substitute maintains the same 1 MOhm resistance, ±1% tolerance, 0.05W power rating, 0201 package, and AEC-Q200 automotive qualification. The primary difference is product lifecycle status.

Q: What does "Not For New Designs" mean for the original part?

A: This designation indicates the manufacturer has transitioned this part number out of active production. While existing inventory may be available, the manufacturer recommends using the active equivalent (RK73G1HTTCM1004F) for new designs and ongoing production.

Q: Are there any package or footprint differences between these parts?

A: No. Both components use the 0201 (0603 metric) package with identical dimensions: 0.024" L x 0.012" W (0.60mm x 0.30mm) and maximum seated height of 0.010" (0.26mm). PCB footprints are interchangeable.

Q: Do both parts meet automotive standards?

A: Yes. Both RK73G1HTTC1004F and RK73G1HTTCM1004F are AEC-Q200 qualified for automotive applications and operate across the -55°C to 155°C temperature range.

Q: Is RoHS compliance maintained in the substitute?

A: Yes. Both parts are ROHS3 compliant with MSL rating of 1 (Unlimited), ensuring equivalent environmental and regulatory compliance.
