Substitute Part Grouping Explanation

Substitution eligibility for the RK73H2HTTE1101F is determined by strict equivalence across the following parameters:

  • Resistance value: 1.1 kOhms
  • Tolerance: ±1%
  • Power rating: 0.75W
  • Package: 2010 (5025 Metric)
  • Composition: Thick Film
  • Temperature coefficient: ±100ppm/°C
  • Operating temperature range: -55°C ~ 155°C
  • Automotive rating: AEC-Q200
  • Moisture sensitivity level: MSL 1
  • RoHS compliance: ROHS3

All identified substitute parts meet these criteria without exception. Substitution is valid only when all parameters remain within the specified tolerances and ratings.

Engineering Selection Recommendations

All substitute parts listed are parametrically equivalent to the RK73H2HTTE1101F and are suitable for direct replacement within the specified electrical and mechanical constraints.

CRCW20101K10FKEF (Vishay Dale) and RMCF2010FT1K10 (Stackpole Electronics Inc) maintain Active product status, ensuring long-term availability and continued manufacturer support for new designs.

ERJ-12SF1101U (Panasonic Electronic Components) carries a "Not For New Designs" status. While electrically and mechanically equivalent, this part is suitable only for legacy system maintenance, repair, or continuation of existing production runs where design changes are not feasible.

Selection between active alternatives should be based on supply chain logistics, lead time requirements, and established vendor relationships, as all active options provide identical electrical performance and compliance certifications.

Frequently Asked Questions (FAQ)

Q: Can ERJ-12SF1101U be used in new product designs? A: ERJ-12SF1101U carries a "Not For New Designs" status from Panasonic. While electrically and mechanically equivalent, it is intended for legacy applications only. CRCW20101K10FKEF or RMCF2010FT1K10 are recommended for new designs.

Q: Are all substitute parts automotive-qualified? A: Yes. All listed substitutes carry AEC-Q200 automotive qualification and operate across the identical temperature range of -55°C to 155°C.

Q: Do substitute parts require PCB layout modifications? A: No. All substitute parts use the identical 2010 (5025 Metric) package with matching footprint dimensions (0.197" L x 0.098" W, 0.028" maximum seated height). Direct PCB substitution is possible without layout changes.

Q: What is the significance of MSL 1 rating? A: MSL 1 (Moisture Sensitivity Level 1) indicates unlimited shelf life without moisture bake requirements. All listed parts share this rating, eliminating moisture management concerns during storage and handling.

Q: Are all substitutes RoHS3 compliant? A: Yes. All listed parts maintain ROHS3 compliance, meeting current environmental and regulatory requirements for electronic component manufacturing and use.
