Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ERD-S2TJ1R1V is determined by the following mandatory parameters:

• Resistance value: 1.1 Ohms
• Tolerance: ±5%
• Power rating: 0.25W (1/4W)
• Composition: Carbon Film
• Package: Axial through-hole
• Operating temperature range: -55°C to 155°C minimum
• Termination count: 2

The substitute parts listed below meet all these core electrical and mechanical requirements. Variations in physical dimensions, temperature coefficient, and product status are noted but do not disqualify substitution eligibility when the primary parameters align.

Engineering Selection Recommendations

CFM14JT1R10 (Stackpole Electronics Inc) is the primary substitute option. This part maintains identical electrical specifications and the closest physical dimensions to the original ERD-S2TJ1R1V. The CFM14JT1R10 is actively manufactured, ROHS3 compliant, and includes flame retardant coating with safety features. The marginal difference in temperature coefficient (±400ppm/°C versus ±350ppm/°C) and physical length (3.30mm versus 3.20mm) remains within acceptable tolerances for most applications.

CFR-25JB-52-1R1 (YAGEO) is a secondary substitute option. This part meets all core electrical requirements and is actively manufactured with ROHS3 compliance. However, the larger physical dimensions (0.094" Dia x 0.248" L) may require PCB layout verification to ensure mechanical fit in existing designs. The asymmetric temperature coefficient (-500/+350ppm/°C) should be evaluated for temperature-sensitive applications.

Frequently Asked Questions (FAQ)

Q: Can CFM14JT1R10 be used as a direct replacement for ERD-S2TJ1R1V?

A: Yes. Both parts share identical resistance (1.1 Ohms), tolerance (±5%), power rating (0.25W), composition (carbon film), and operating temperature range (-55°C to 155°C). Physical dimensions are nearly identical, with only 0.10mm difference in length.

Q: What is the primary difference between CFM14JT1R10 and CFR-25JB-52-1R1?

A: The CFM14JT1R10 maintains closer physical dimensions to the original part (1.70mm x 3.30mm) and includes flame retardant coating. The CFR-25JB-52-1R1 has larger dimensions (2.40mm x 6.30mm) and an asymmetric temperature coefficient. Both are electrically equivalent.

Q: Does physical size matter when substituting these resistors?

A: Physical dimensions must be verified against PCB layout constraints. The CFM14JT1R10 is nearly identical to the original. The CFR-25JB-52-1R1 is significantly larger and may require layout modifications.

Q: Are both substitute parts RoHS compliant?

A: Yes. Both CFM14JT1R10 and CFR-25JB-52-1R1 are ROHS3 compliant. The original ERD-S2TJ1R1V RoHS status is not specified.

Q: Which substitute has better long-term availability?

A: Both CFM14JT1R10 and CFR-25JB-52-1R1 are actively manufactured. The CFM14JT1R10 is recommended for new designs due to superior dimensional compatibility and active product status with flame retardant features.
