Substitute Part Grouping Explanation

Substitution eligibility for the CRCW0805430RFKTC is determined by strict equivalence across the following parameters:

Resistance value: 430 Ohms
Tolerance: ±1%
Power rating: 0.125W (1/8W)
Package: 0805 (2012 Metric)
Composition: Thick Film
Temperature coefficient: ±100ppm/°C
Operating temperature range: -55°C ~ 155°C
Number of terminations: 2

All substitute parts listed meet these core electrical and mechanical requirements. Variations in physical dimensions (height, length, width) within the 0805 package specification, RoHS compliance status, and packaging format (Tape & Reel vs. Cut Tape) do not affect functional substitutability but may impact procurement, assembly, and regulatory compliance considerations.

Engineering Selection Recommendations

CRCW0805430RFKEA (Vishay Dale) is the direct equivalent from the same manufacturer with identical electrical specifications and package dimensions. This part is ROHS3 compliant and maintains active production status, making it the primary substitute when supply of CRCW0805430RFKTC is constrained.

ERJ-6ENF4300V (Panasonic Electronic Components), RMCF0805FT430R (Stackpole Electronics Inc), and KTR10EZPF4300 (Rohm Semiconductor) are functionally equivalent alternatives from established automotive-qualified manufacturers. All three maintain active production status and ROHS3 compliance. Physical height variations (0.028", 0.026", and 0.026" respectively) remain within 0805 package tolerances and do not affect PCB assembly compatibility.

CR0805-FX-4300ELF (Bourns Inc.) is an active alternative with moisture-resistant composition. This part is ROHS3 compliant and suitable for applications requiring enhanced environmental protection.

MCR10ERTF4300 (Rohm Semiconductor) is discontinued at DiGi Electronics and should not be selected for new designs or long-term production applications.

Frequently Asked Questions (FAQ)

Q: Can CRCW0805430RFKEA replace CRCW0805430RFKTC directly?

A: Yes. CRCW0805430RFKEA is manufactured by Vishay Dale with identical electrical specifications (430 Ohms ±1%, 0.125W, ±100ppm/°C, -55°C to 155°C) and package dimensions. The primary difference is ROHS3 compliance status. Both parts are pin-compatible and functionally interchangeable.

Q: Are cross-manufacturer substitutes electrically equivalent?

A: Yes. ERJ-6ENF4300V, RMCF0805FT430R, KTR10EZPF4300, and CR0805-FX-4300ELF all meet the core electrical parameters: 430 Ohms ±1% resistance, 0.125W power rating, ±100ppm/°C temperature coefficient, and -55°C to 155°C operating range. All are qualified for 0805 (2012 Metric) package footprints.

Q: Do height differences between substitute parts affect PCB assembly?

A: Height variations (0.020" to 0.028") are within 0805 package specification tolerances. These differences do not affect solder reflow, component placement, or electrical performance. Standard pick-and-place equipment accommodates this range without adjustment.

Q: Which substitute part has the best availability?

A: ERJ-6ENF4300V (Panasonic) shows the highest inventory level at 104,811 pieces. CRCW0805430RFKEA (Vishay Dale) has 10,412 pieces available. Both maintain active production status and support long-term supply continuity.

Q: Is MCR10ERTF4300 suitable for new designs?

A: No. MCR10ERTF4300 is discontinued at DiGi Electronics and should not be specified for new product designs or ongoing production. Select from active alternatives: CRCW0805430RFKEA, ERJ-6ENF4300V, RMCF0805FT430R, KTR10EZPF4300, or CR0805-FX-4300ELF.

Q: What is the difference between Tape & Reel and Cut Tape packaging?

A: Tape & Reel (TR) packaging is supplied on continuous carrier tape suitable for automated assembly lines. Cut Tape (CT) is supplied in shorter tape segments. Both formats contain identical components. Selection depends on production volume and assembly equipment compatibility, not electrical performance.
