Substitute Part Grouping Explanation

Substitute parts for the RC6432F7152CS are qualified based on the following criteria:

Electrical Parameters (Mandatory Match):

• Resistance value: 71.5 kOhms
• Tolerance: ±1%
• Power rating: 1W
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C to 155°C

Mechanical Parameters (Mandatory Match):

• Package / Case: 2512 (6432 Metric)
• Number of terminations: 2
• Composition: Thick Film

Compliance Parameters (Mandatory Match):

• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)
• REACH Status: REACH Unaffected

Allowable Variations:

• Manufacturer identity (different suppliers)
• Packaging format (Tape & Reel vs. bulk)
• Physical dimensions within tolerance (length, width, height within ±0.002" to ±0.004")
• Additional certifications (AEC-Q200 automotive qualification is additive, not restrictive)

Two substitute parts meet these criteria: AC2512FK-0771K5L (YAGEO) and CRCW251271K5FKEG (Vishay Dale). Both are functionally equivalent with identical electrical specifications and package compatibility.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection (RC6432F7152CS - Samsung Electro-Mechanics): Use when Samsung-specific supply chain requirements, existing qualification documentation, or preferred vendor agreements mandate this manufacturer. Active production status and ROHS3 compliance support standard applications.

Upgrade Selection (AC2512FK-0771K5L - YAGEO): Select this substitute when automotive AEC-Q200 qualification is required or preferred. Identical electrical and mechanical specifications with added automotive certification. Tape & Reel packaging supports automated assembly processes. Higher inventory availability (4902 units) improves procurement lead times.

Alternative Selection (CRCW251271K5FKEG - Vishay Dale): Choose this substitute for automotive applications requiring AEC-Q200 qualification with Vishay Dale supply chain preference. Highest inventory availability (6712 units) supports rapid procurement. Tape & Reel packaging enables automated placement. Dimensions remain within 2512 package tolerance stack.

All three parts maintain identical electrical performance, temperature stability, and regulatory compliance. Selection should be based on supply chain strategy, packaging requirements, and automotive qualification necessity rather than technical performance differences.

Frequently Asked Questions (FAQ)

Q: Can AC2512FK-0771K5L replace RC6432F7152CS in non-automotive applications?

A: Yes. AC2512FK-0771K5L meets all electrical, mechanical, and compliance requirements of RC6432F7152CS. AEC-Q200 automotive qualification is an additional feature that does not restrict use in non-automotive circuits. Electrical performance is identical.

Q: Are there dimensional compatibility concerns when substituting between these three parts?

A: Dimensional variations are within acceptable tolerance for 2512 package footprints. Length ranges from 0.248" to 0.250" (6.30mm to 6.35mm), width from 0.122" to 0.126" (3.10mm to 3.20mm), and height from 0.026" to 0.028" (0.65mm to 0.70mm). These variations fall within standard PCB pad design tolerances for 2512 components and do not require layout modification.

Q: What is the difference between bulk and Tape & Reel packaging for these resistors?

A: RC6432F7152CS packaging format is not specified in available data. AC2512FK-0771K5L and CRCW251271K5FKEG are supplied in Tape & Reel format, which supports automated pick-and-place assembly. Tape & Reel packaging typically offers cost advantages for high-volume production and improves assembly efficiency. Bulk packaging may be available upon request from manufacturers.

Q: Do all three parts have identical moisture sensitivity requirements?

A: Yes. All three parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions. Standard handling procedures apply without special drying or baking requirements prior to soldering.

Q: Which substitute offers the best supply chain availability?

A: CRCW251271K5FKEG (Vishay Dale) provides the highest inventory availability at 6712 units in stock, followed by AC2512FK-0771K5L (YAGEO) at 4902 units. RC6432F7152CS (Samsung) has 818 units available. Inventory levels support procurement planning and lead time management.

Q: Are there performance differences in temperature coefficient between these parts?

A: No. All three parts specify ±100ppm/°C temperature coefficient across the -55°C to 155°C operating range. Resistance stability over temperature is identical across all substitutes.

Q: Can these parts be used interchangeably in existing designs without re-qualification?

A: Electrical and mechanical interchangeability is confirmed. Design re-qualification depends on your organization's change control procedures and whether the design was originally qualified to specific manufacturer part numbers. Consult your quality and engineering documentation requirements.
