Key Parameters

Substitute Part Grouping Explanation

Substitution of the ERD-S1TJ751V is determined by strict equivalence across the following critical parameters:

• Resistance value: 750 Ohms (exact match required)
• Tolerance: ±5% (electrical accuracy specification)
• Power rating: 0.5W / 1/2W (thermal dissipation capability)
• Composition: Carbon Film (material specification)
• Package: Axial (mechanical form factor and PCB compatibility)
• Operating temperature range: -55°C to 155°C (environmental operating limits)
• Termination count: 2 (electrical connectivity)

The CFM12JT750R from Stackpole Electronics Inc meets all these criteria and qualifies as a direct functional equivalent. Both parts share identical electrical specifications and mechanical compatibility, enabling direct substitution in circuit designs.

Engineering Selection Recommendations

The CFM12JT750R is the qualified substitute for the obsolete ERD-S1TJ751V. Selection is based on the following factors:

• Electrical equivalence: Both parts deliver identical resistance, tolerance, and power dissipation characteristics across the specified operating temperature range.
• Mechanical compatibility: Axial package form factor and physical dimensions are compatible with existing PCB layouts. The CFM12JT750R length of 6.50mm versus the original 6.35mm represents a negligible difference within standard PCB design tolerances.
• Product availability: The CFM12JT750R is in active production status with substantial inventory availability (11,519 pcs), ensuring supply chain continuity.
• Regulatory compliance: The CFM12JT750R carries ROHS3 compliance and REACH unaffected status, meeting current environmental and regulatory requirements for new designs and production.

Frequently Asked Questions (FAQ)

Q: Can the CFM12JT750R be used as a direct replacement for the ERD-S1TJ751V?

A: Yes. Both parts are electrically and mechanically equivalent. They share identical resistance (750 Ohms), tolerance (±5%), power rating (0.5W), composition (carbon film), package type (axial), and operating temperature range (-55°C to 155°C). The minor dimensional difference (0.006" length variation) does not affect PCB compatibility.

Q: What is the reason for substitution?

A: The ERD-S1TJ751V is classified as obsolete. The CFM12JT750R provides functional continuity for designs requiring this resistance value and power rating while ensuring ongoing component availability and regulatory compliance.

Q: Are there any compliance differences between the two parts?

A: The CFM12JT750R carries ROHS3 compliance and REACH unaffected certification. The original part's compliance status is not specified. For applications subject to environmental regulations, the CFM12JT750R meets current standards.

Q: Will the CFM12JT750R fit in existing PCB layouts designed for the ERD-S1TJ751V?

A: Yes. The axial package form factor and physical dimensions are compatible. The CFM12JT750R is 0.006" longer (6.50mm vs 6.35mm), which is within standard PCB design tolerances and does not require layout modifications.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution is determined by matching resistance value, tolerance, power rating, composition, package type, operating temperature range, and termination count. All these parameters are identical between the ERD-S1TJ751V and CFM12JT750R.
