Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC6432F1620CS is determined by strict equivalence across the following parameters:

Mandatory Matching Criteria:

• Resistance value: 162 Ohms
• Tolerance: ±1%
• Power rating: 1W
• Package type: 2512 (6432 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C
• RoHS compliance: ROHS3
• Moisture sensitivity level: 1 (Unlimited)
• Termination count: 2

All identified substitute parts meet these criteria. Variations in packaging format (Tape & Reel vs. Cut Tape), physical dimensions within tolerance, and additional certifications (such as AEC-Q200 automotive qualification) do not disqualify substitution but may influence selection based on application requirements and inventory availability.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Active Product Status):

CRCW2512162RFKEG (Vishay Dale) and RMCF2512FT162R (Stackpole Electronics Inc) are recommended as primary substitutes. Both parts maintain active product status, ensuring long-term availability and supply chain stability. CRCW2512162RFKEG offers Tape & Reel packaging with AEC-Q200 automotive qualification. RMCF2512FT162R provides the highest inventory availability (17,902 pcs) in Cut Tape format with AEC-Q200 certification.

Secondary Substitute (Legacy Status):

ERJ-1TNF1620U (Panasonic Electronic Components) is electrically and mechanically equivalent but carries "Not For New Designs" product status. This part is suitable for replacement applications, legacy system maintenance, or repair scenarios where existing design validation exists. New design implementations should prioritize active-status alternatives.

Selection Criteria:

• For high-volume production: RMCF2512FT162R (highest inventory)
• For automotive applications: CRCW2512162RFKEG or RMCF2512FT162R (both AEC-Q200 qualified)
• For tape packaging requirements: CRCW2512162RFKEG or ERJ-1TNF1620U
• For cut tape requirements: RMCF2512FT162R

Frequently Asked Questions (FAQ)

Q: Can CRCW2512162RFKEG replace RC6432F1620CS directly?

A: Yes. Both parts share identical electrical specifications (162 Ohms ±1%, 1W, ±100ppm/°C) and mechanical compatibility (2512 package, -55°C to 155°C operating range). The primary difference is packaging format (Tape & Reel vs. bulk) and the addition of AEC-Q200 automotive certification on the Vishay part, which does not prevent substitution.

Q: Why is ERJ-1TNF1620U marked "Not For New Designs"?

A: This designation indicates Panasonic has discontinued active development and production planning for this part number. While electrically and mechanically equivalent, it should not be selected for new product designs. Existing designs using this part may continue with available inventory for maintenance and repair.

Q: Are there physical dimension differences between substitutes?

A: Minor variations exist within tolerance. RC6432F1620CS and RMCF2512FT162R both measure 0.248" L x 0.126" W (6.30mm x 3.20mm). CRCW2512162RFKEG measures 0.248" L x 0.124" W (6.30mm x 3.15mm). ERJ-1TNF1620U measures 0.252" L x 0.126" W (6.40mm x 3.20mm). All dimensions remain within 2512 package specification and do not affect PCB layout compatibility.

Q: What is the significance of AEC-Q200 certification on substitute parts?

A: AEC-Q200 is an automotive industry qualification standard. CRCW2512162RFKEG and RMCF2512FT162R carry this certification, indicating suitability for automotive applications. RC6432F1620CS does not list this certification. If automotive qualification is required, select AEC-Q200 certified substitutes.

Q: Can I use these parts interchangeably in existing assemblies?

A: Yes, provided the assembly design accommodates the packaging format. If the original design uses bulk packaging, verify that substitute tape or cut tape formats are compatible with your assembly equipment. All electrical and thermal characteristics are equivalent.

Q: Which substitute offers the best supply availability?

A: RMCF2512FT162R (Stackpole Electronics Inc) currently has the highest inventory at 17,902 pcs. CRCW2512162RFKEG (Vishay Dale) has 2,976 pcs available. Both ensure supply continuity for production requirements.
