Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ERD-S2TJ2R2V are qualified based on the following electrical and mechanical parameters:

• Resistance value: 2.2 Ohms (exact match required)
• Tolerance: ±5% (exact match required)
• Power rating: 0.25W / 1/4W (exact match required)
• Composition: Carbon Film (exact match required)
• Package: Axial through-hole (exact match required)
• Operating temperature range: -55°C to 155°C (minimum requirement)
• Number of terminations: 2 (exact match required)

All substitute parts listed meet these core electrical and mechanical criteria. Physical dimensions may vary within acceptable assembly tolerances for axial component insertion and soldering.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts are active products with current manufacturing status, providing supply chain continuity for the obsolete ERD-S2TJ2R2V.

CFM14JT2R20 (Stackpole Electronics Inc) offers the highest inventory availability at 43,724 pieces and includes flame retardant coating with safety features. This part is ROHS3 compliant and REACH unaffected, making it suitable for applications requiring enhanced safety certifications.

CFR16J2R2 (TE Connectivity Passive Product) maintains identical temperature coefficient specifications (±350ppm/°C) to the original part and provides 1,084 pieces in stock. ROHS3 compliance is confirmed with REACH status vendor-defined.

CFR-25JR-52-2R2 (YAGEO) is available in the highest quantity at 5,722 pieces with ROHS3 compliance and REACH unaffected status. This part features asymmetrical temperature coefficient (-500/+350ppm/°C) and larger physical dimensions compared to the original specification.

Selection should prioritize product status (all active), compliance certifications (all ROHS3 compliant), and inventory availability based on production volume requirements.

Frequently Asked Questions (FAQ)

Q: Can CFM14JT2R20 be used as a direct replacement for ERD-S2TJ2R2V?

A: Yes. Both parts share identical electrical specifications: 2.2 Ohms ±5% at 0.25W power rating with carbon film composition. Operating temperature ranges and termination counts are equivalent. Physical dimensions differ slightly (3.30mm vs 3.20mm length), but both are within acceptable axial component assembly tolerances.

Q: What is the difference between CFR16J2R2 and CFR-25JR-52-2R2?

A: Both are functionally equivalent 2.2 Ohm ±5% 1/4W axial carbon film resistors. CFR16J2R2 maintains the original temperature coefficient of ±350ppm/°C, while CFR-25JR-52-2R2 specifies -500/+350ppm/°C. CFR-25JR-52-2R2 has larger physical dimensions (6.30mm length vs 4.60mm), which may affect board layout considerations.

Q: Are all substitute parts RoHS compliant?

A: Yes. CFM14JT2R20, CFR16J2R2, and CFR-25JR-52-2R2 are all ROHS3 compliant, meeting current environmental and safety regulations.

Q: Does the flame retardant coating on CFM14JT2R20 affect electrical performance?

A: No. The flame retardant coating is a safety feature that does not alter the core electrical parameters. Resistance, tolerance, power rating, and temperature coefficient remain unchanged.

Q: Which substitute part has the best inventory availability?

A: CFM14JT2R20 has the highest stock level at 43,724 pieces, followed by CFR-25JR-52-2R2 at 5,722 pieces and CFR16J2R2 at 1,084 pieces.

Q: Can physical dimension differences affect circuit board assembly?

A: Axial resistor dimensions may vary within standard assembly tolerances. CFR-25JR-52-2R2 has notably larger dimensions (2.40mm diameter x 6.30mm length) compared to the original (1.70mm diameter x 3.20mm length). Board layout verification is necessary if space constraints are critical.
