RC6432F8871CS Equivalent & Substitute Parts Reference

Part Overview

The RC6432F8871CS is an 8.87 kOhms ±1% 1W chip resistor manufactured by Samsung Electro-Mechanics in the 2512 (6432 Metric) package. This thick film, moisture-resistant component operates across -55°C to 155°C and is ROHS3 compliant with MSL 1 rating. The part is currently in active production status with 1072 units available in inventory.

Substitute parts become necessary when the primary part experiences supply constraints, extended lead times, or when design requirements permit alternative qualified sources. The ERJ-1TNF8871U from Panasonic Electronic Components provides electrical and mechanical equivalence, though it carries a "Not For New Designs" status and includes automotive AEC-Q200 qualification.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC6432F8871CS is determined by strict equivalence across the following parameters:

Electrical Parameters (Non-negotiable):

• Resistance value: 8.87 kOhms
• Tolerance: ±1%
• Power rating: 1W
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C to 155°C

Mechanical Parameters (Non-negotiable):

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

Compliance Parameters (Required):

• RoHS3 compliance
• MSL 1 rating
• REACH unaffected status

The ERJ-1TNF8871U meets all electrical and mechanical equivalence criteria. Physical dimensions show minor variation (0.252" L vs 0.248" L; 0.028" H vs 0.026" H maximum seated height), which remains within standard PCB design tolerances for 2512 package footprints. Both parts maintain identical resistance, tolerance, power rating, temperature coefficient, and operating temperature specifications.

Parameter Comparison

Engineering Selection Recommendations

For Active Production Designs: The RC6432F8871CS is the primary selection. It maintains active product status with established supply availability (1072 units in stock) and is suitable for new design implementations. All regulatory requirements (ROHS3, REACH unaffected) are met.

For Existing Designs Requiring Substitution: The ERJ-1TNF8871U from Panasonic Electronic Components provides full electrical and mechanical equivalence. Although designated "Not For New Designs," it remains a valid substitute for existing production or maintenance applications. The part carries AEC-Q200 automotive qualification, which exceeds the baseline requirements of the primary part and may provide additional reliability assurance in demanding environments.

Packaging Consideration: The RC6432F8871CS is supplied in standard packaging format. The ERJ-1TNF8871U is supplied in Tape & Reel (TR) format, which may require adjustment to assembly processes if transitioning between suppliers.

Compliance Status: Both parts satisfy ROHS3 compliance and MSL 1 requirements. No regulatory barriers exist to substitution in either direction for applications within the specified operating temperature range.

Frequently Asked Questions (FAQ)

Q: Can ERJ-1TNF8871U be used as a direct replacement for RC6432F8871CS in new designs?

A: Electrically and mechanically, yes. However, the ERJ-1TNF8871U carries "Not For New Designs" status from the manufacturer. For new production designs, the RC6432F8871CS is the recommended selection. The Panasonic part is appropriate for sustaining production of existing designs or as a secondary source when primary supply is unavailable.

Q: Are there dimensional differences that affect PCB layout?

A: Minor dimensional variations exist. The ERJ-1TNF8871U is 0.004" (0.10mm) longer and 0.002" (0.04mm) taller than the RC6432F8871CS. These differences fall within standard PCB design tolerances for 2512 package footprints and do not require layout modification.

Q: Does the AEC-Q200 rating on the Panasonic part affect compatibility?

A: No. AEC-Q200 is an additional automotive qualification that does not conflict with standard industrial applications. It indicates enhanced reliability testing and is compatible with any application accepting the base specifications.

Q: What is the impact of different packaging formats?

A: The RC6432F8871CS uses standard packaging; the ERJ-1TNF8871U uses Tape & Reel (TR) format. This affects receiving, storage, and assembly processes but does not impact the component's electrical or mechanical performance. Assembly equipment must be compatible with the respective packaging format.

Q: Are both parts suitable for the full -55°C to 155°C operating range?

A: Yes. Both parts are rated for identical operating temperature ranges and maintain ±100ppm/°C temperature coefficient across this span.

Q: What is MSL 1 rating and why is it important?

A: MSL 1 (Moisture Sensitivity Level 1) indicates unlimited shelf life without special moisture control requirements. Both parts carry this rating, meaning standard storage conditions are acceptable without desiccant or controlled humidity environments.
