Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RCS3216F431CS are qualified based on strict equivalence of the following parameters:

Electrical Equivalence Criteria:

• Resistance value: 430 Ohms
• Tolerance: ±1%
• Power rating: 0.25W (1/4W)
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C

Mechanical Equivalence Criteria:

• Package type: 1206 (3216 Metric)
• Number of terminations: 2
• Physical dimensions compatible with 1206 footprint

Compliance Criteria:

• RoHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)
• REACH Unaffected status

All identified substitute parts meet these criteria. Variations in physical dimensions (length, width, height) within the 1206 package specification, packaging format (Cut Tape, Tape & Reel), and additional certifications (such as AEC-Q200 automotive qualification) do not affect functional substitutability for general applications.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Active Product Status):

AC1206FR-07430RL, CR1206-FX-4300ELF, CRCW1206430RFKEA, and RC1206FR-07430RL are all qualified substitutes with Active product status. These parts maintain full electrical and mechanical equivalence to the RCS3216F431CS and are suitable for new designs and ongoing production.

Secondary Substitute (Legacy Status):

ERJ-8ENF4300V is electrically and mechanically equivalent but carries "Not For New Designs" product status. This part is available in high inventory (56,464 pieces) and remains suitable for replacement in existing applications or legacy system maintenance. Use of this part in new designs is not recommended.

Compliance Alignment:

All substitute parts are ROHS3 compliant, REACH unaffected, and carry MSL Level 1 (unlimited moisture sensitivity). No additional environmental or regulatory considerations differentiate the substitute options.

Packaging Considerations:

Substitute parts are available in different packaging formats (Cut Tape, Tape & Reel). Selection should align with procurement and assembly process requirements. Packaging format does not affect electrical or mechanical performance.

Frequently Asked Questions (FAQ)

Q: Can AC1206FR-07430RL replace RCS3216F431CS in existing circuits?

A: Yes. AC1206FR-07430RL meets all electrical specifications (430 Ω ±1%, 0.25W, ±100ppm/°C, -55°C ~ 155°C) and mechanical requirements (1206 package, 2 terminations). Both parts are ROHS3 compliant with MSL Level 1. Direct substitution is functionally equivalent.

Q: What is the difference between CR1206-FX-4300ELF and CRCW1206430RFKEA?

A: Both parts are electrically identical (430 Ω ±1%, 0.25W, ±100ppm/°C, -55°C ~ 155°C) and mechanically compatible (1206 package). The primary differences are manufacturer (Bourns vs. Vishay Dale), packaging format (Tape & Reel for both), and minor physical dimension variations within 1206 specification tolerances. CRCW1206430RFKEA includes AEC-Q200 automotive qualification; CR1206-FX-4300ELF does not. For non-automotive applications, both are interchangeable.

Q: Why is ERJ-8ENF4300V marked "Not For New Designs"?

A: ERJ-8ENF4300V carries legacy product status from Panasonic Electronic Components. This designation indicates the manufacturer is not actively promoting this part for new circuit designs. However, the part remains electrically and mechanically equivalent to RCS3216F431CS and is suitable for replacement in existing applications. New designs should prioritize parts with Active status.

Q: Are there any temperature or environmental performance differences between substitute parts?

A: No. All substitute parts share identical operating temperature range (-55°C ~ 155°C) and temperature coefficient (±100ppm/°C). Moisture resistance features vary slightly by manufacturer (anti-sulfur and moisture resistant for RCS3216F431CS; moisture resistant for most substitutes), but all parts maintain MSL Level 1 rating, indicating unlimited moisture sensitivity protection.

Q: Does package size variation affect substitutability?

A: No. All parts conform to 1206 (3216 Metric) package specification. Minor dimensional variations (length 0.122" to 0.126", height 0.024" to 0.030") fall within standard 1206 tolerances and do not affect PCB footprint compatibility or circuit performance.

Q: Which substitute part offers the best availability?

A: RC1206FR-07430RL (YAGEO) offers the highest inventory at 42,804 pieces, followed by ERJ-8ENF4300V (Panasonic) at 56,464 pieces. For Active product status with high availability, RC1206FR-07430RL is the optimal choice.
