Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RC1005F431CS are classified based on strict electrical and mechanical parameter matching. The primary substitution criteria are:

Core Matching Parameters:

• Resistance value: 430 Ohms
• Tolerance: ±1%
• Package: 0402 (1005 Metric)
• Composition: Thick Film
• Temperature Coefficient: ±100ppm/°C
• Operating Temperature: -55°C to 155°C
• Terminations: 2
• RoHS3 Compliance
• MSL Level: 1 (Unlimited)

Substitution Categories:

Direct Equivalents maintain identical electrical specifications and power rating (0.063W / 1/16W):

• CR0402-FX-4300GLF (Bourns Inc.)
• CRG0402F430R (TE Connectivity Passive Product)
• RC0402FR-07430RL (YAGEO)
• AC0402FR-07430RL (YAGEO)
• CRCW0402430RFKED (Vishay Dale)
• RMCF0402FT430R (Stackpole Electronics Inc)

Upgrade Substitute provides higher power rating while maintaining all other core parameters:

• ERJ-2RKF4300X (Panasonic Electronic Components) – 0.1W (1/10W) power rating

All substitute parts share identical physical dimensions, thermal characteristics, and compliance certifications with the main part, enabling direct functional replacement in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement Applications:

Parts CR0402-FX-4300GLF, CRG0402F430R, RC0402FR-07430RL, AC0402FR-07430RL, CRCW0402430RFKED, and RMCF0402FT430R are electrically and mechanically equivalent to RC1005F431CS. All maintain identical resistance, tolerance, power rating, package dimensions, and thermal characteristics. Selection among these direct equivalents may be based on packaging preference (Tape & Reel versus Cut Tape & Digi-Reel), manufacturer availability, or supply chain requirements. All direct equivalents carry ROHS3 compliance and MSL 1 rating.

For Applications Requiring Higher Power Margin:

ERJ-2RKF4300X from Panasonic Electronic Components provides an upgrade path with 0.1W (1/10W) power rating compared to the 0.063W (1/16W) rating of the main part. This higher power rating accommodates applications with greater thermal stress or design margin requirements. The ERJ-2RKF4300X maintains all other electrical parameters and compliance certifications identical to RC1005F431CS.

Automotive Applications:

AC0402FR-07430RL, CRCW0402430RFKED, RMCF0402FT430R, and ERJ-2RKF4300X carry AEC-Q200 automotive qualification. These parts are suitable for automotive-grade applications requiring enhanced reliability standards.

Packaging Considerations:

RC0402FR-07430RL and ERJ-2RKF4300X are supplied in Cut Tape & Digi-Reel packaging, while CR0402-FX-4300GLF, CRG0402F430R, AC0402FR-07430RL, CRCW0402430RFKED, and RMCF0402FT430R are supplied in Tape & Reel format. Packaging selection depends on assembly equipment compatibility and procurement volume requirements.

Frequently Asked Questions (FAQ)

Q: Can ERJ-2RKF4300X be used as a direct replacement for RC1005F431CS?

A: ERJ-2RKF4300X is functionally compatible with RC1005F431CS for all electrical parameters except power rating. The ERJ-2RKF4300X provides 0.1W (1/10W) power dissipation compared to RC1005F431CS at 0.063W (1/16W). This higher power rating is a superset capability and does not create incompatibility. The part is suitable for direct replacement in applications where the original power rating is adequate or where additional thermal margin is beneficial.

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

A: Tape & Reel packaging supplies components on continuous carrier tape wound on reels, optimized for high-volume automated assembly. Cut Tape & Digi-Reel packaging provides components on cut tape segments or alternative reel formats, suitable for lower-volume production or mixed-component assembly. Both packaging formats contain identical components with identical electrical specifications. Selection depends on assembly equipment capability and order quantity requirements.

Q: Are all substitute parts ROHS3 compliant?

A: All substitute parts listed carry ROHS3 compliance certification, matching the compliance status of RC1005F431CS. All parts are also REACH Unaffected and carry MSL 1 (Unlimited) moisture sensitivity level.

Q: Which substitute parts have automotive qualification?

A: AC0402FR-07430RL, CRCW0402430RFKED, RMCF0402FT430R, and ERJ-2RKF4300X carry AEC-Q200 automotive qualification. These parts are suitable for automotive applications requiring enhanced reliability standards. RC1005F431CS, CR0402-FX-4300GLF, CRG0402F430R, and RC0402FR-07430RL do not carry AEC-Q200 designation.

Q: Can substitute parts be mixed in the same production batch?

A: All substitute parts maintain identical electrical specifications, package dimensions, and thermal characteristics. Parts may be used interchangeably within the same circuit design. However, procurement and assembly documentation should specify the approved part number to maintain traceability and supply chain consistency.

Q: What are the physical dimensions of all substitute parts?

A: All substitute parts share identical 0402 (1005 Metric) package dimensions: 0.039" L × 0.020" W (1.00mm × 0.50mm) with maximum seated height of 0.016" (0.40mm), except AC0402FR-07430RL which has maximum seated height of 0.015" (0.37mm). These dimensions are compatible with standard 0402 PCB footprints.

Q: What is the temperature coefficient specification for all parts?

A: All substitute parts maintain ±100ppm/°C temperature coefficient, identical to RC1005F431CS. Operating temperature range is -55°C to 155°C across all parts.
