Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC6432F9310CS is determined by the following critical parameters:

Electrical Compatibility Requirements:

• Resistance value must equal 931 Ohms
• Tolerance must be ±1% or tighter
• Temperature coefficient must be ±100ppm/°C or better
• Operating temperature range must encompass -55°C ~ 155°C

Mechanical Compatibility Requirements:

• Package format must be 2512 (6432 Metric)
• Thick film composition required
• Number of terminations must be 2

Compliance Requirements:

• RoHS3 compliance mandatory
• MSL rating must be 1 (Unlimited) or equivalent
• REACH Unaffected status required

Power Rating Consideration: Substitute parts may have equal or higher power ratings (1W or greater) provided all other parameters remain within specification. Higher power ratings do not disqualify a part from substitution when electrical and mechanical parameters are identical.

Parameter Comparison

Engineering Selection Recommendations

Primary Part: RC6432F9310CS (Samsung Electro-Mechanics)

Selection criteria: Use as primary component when Samsung supply chain is established and 1W power rating is sufficient for circuit requirements. Active product status ensures continued availability. ROHS3 compliance and MSL 1 rating support unrestricted storage and handling.

Substitute Part: CRM2512-FX-9310ELF (Bourns Inc.)

Selection criteria: Acceptable as direct substitute when Samsung part availability is constrained. The 2W power rating provides additional thermal margin without affecting circuit performance. Identical electrical specifications (931 Ohms ±1%, ±100ppm/°C, -55°C ~ 155°C) ensure functional equivalence. Mechanical compatibility confirmed within 2512 package envelope. ROHS3 compliance and MSL 1 rating maintain regulatory and environmental handling requirements. Bourns CRM2512 series availability (4951 pcs in stock) supports production continuity.

Both parts satisfy all compliance requirements: ROHS3 Compliant, REACH Unaffected, EAR99 classification, and HTSUS code 8533.21.0030.

Frequently Asked Questions (FAQ)

Q: Can CRM2512-FX-9310ELF replace RC6432F9310CS in existing designs?

A: Yes. Both parts share identical resistance value (931 Ohms), tolerance (±1%), temperature coefficient (±100ppm/°C), and operating range (-55°C ~ 155°C). The 2512 package format is mechanically compatible. The substitute part's 2W rating exceeds the original 1W specification, providing additional thermal capacity without circuit modification.

Q: Are there dimensional differences between these parts?

A: Minor dimensional variations exist. Length is identical (0.248" / 6.30mm). Width differs by 0.004" (0.10mm): RC6432F9310CS is 0.126" (3.20mm), CRM2512-FX-9310ELF is 0.122" (3.10mm). Height differs by 0.005" (0.14mm): RC6432F9310CS is 0.026" (0.66mm), CRM2512-FX-9310ELF is 0.031" (0.80mm). These variations remain within standard PCB layout tolerances for 2512 package footprints.

Q: Do both parts meet the same compliance standards?

A: Yes. Both parts are ROHS3 Compliant, REACH Unaffected, classified as EAR99, and share HTSUS code 8533.21.0030. Moisture sensitivity level is MSL 1 (Unlimited) for both, permitting unrestricted storage without desiccant requirements.

Q: What is the difference between the "Moisture Resistant" feature of Samsung and "Current Sense" feature of Bourns?

A: These are distinct feature classifications. Samsung's RC6432F9310CS emphasizes moisture resistance in the thick film construction. Bourns' CRM2512-FX-9310ELF is specified for current sensing applications. Both parts maintain identical electrical and environmental specifications. Feature designation reflects intended application context but does not affect substitution eligibility when core parameters match.

Q: Can the substitute part be used in high-temperature applications?

A: Yes. Both parts operate across -55°C ~ 155°C with ±100ppm/°C temperature coefficient. The substitute part's 2W rating provides improved thermal stability at elevated temperatures compared to the 1W original specification.

Q: Is packaging format different between these parts?

A: The main part (RC6432F9310CS) is supplied in standard packaging. The substitute part (CRM2512-FX-9310ELF) is supplied in Tape & Reel (TR) format. Both use identical 2512 (6432 Metric) component package. Tape & Reel format is standard for automated assembly processes and does not affect component performance or compatibility.
