Equivalent & Substitute Parts for 3FL88-130

Part Overview

The 3FL88-130 is a laminated core power transformer manufactured by Tamura, rated at 12VA with dual primary and secondary windings. This through-hole mounted component is designed for applications requiring 115V or 230V primary input with configurable secondary output of either 44V (parallel) or 88V (series) at maximum currents of 260mA or 130mA respectively.

The 3FL88-130 carries an Obsolete product status. Identifying equivalent substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production or repair requirements for systems utilizing this transformer specification.

Parameter Comparison

Engineering Selection Recommendations

The FP88-130 manufactured by Triad Magnetics is a direct functional equivalent to the obsolete 3FL88-130. All critical electrical parameters—power rating, primary and secondary voltages, output currents, and winding configurations—are identical. Physical dimensions and mounting characteristics are equivalent, enabling direct mechanical substitution in through-hole PCB applications.

The FP88-130 offers additional advantages in terms of product lifecycle status (Active versus Obsolete), providing improved long-term availability and supply chain stability. The enhanced isolation voltage rating of 2000Vrms exceeds the original 1500Vrms specification, providing additional safety margin in isolation-critical applications.

The FP88-130 carries ROHS3 compliance certification, supporting regulatory requirements for new designs and manufacturing environments subject to RoHS directives. The Flat Pack™ series designation indicates Triad Magnetics' product line positioning.

Selection of the FP88-130 as a substitute for the 3FL88-130 is supported by complete electrical and mechanical equivalence, superior product status, and enhanced compliance certifications.

Frequently Asked Questions (FAQ)

Q: Can the FP88-130 be used as a direct replacement for the 3FL88-130 in existing designs?

A: Yes. The FP88-130 meets all electrical and mechanical equivalence criteria. Identical power rating, voltage configurations, current ratings, winding arrangements, mounting type, termination style, and physical dimensions enable direct substitution in through-hole PCB applications without design modification.

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

A: Substitution eligibility is determined by equivalence in: 12VA power rating, dual 115V/230V primary winding, dual secondary winding with 44V parallel and 88V series output capability, 260mA parallel and 130mA series maximum output current, laminated core construction, through-hole mounting, PC pin termination, and 63.50mm x 50.80mm x 27.05mm maximum dimensions.

Q: How does the FP88-130 differ from the 3FL88-130?

A: The FP88-130 differs in three areas: (1) Product status is Active rather than Obsolete, improving supply chain availability; (2) Isolation voltage is rated at 2000Vrms compared to 1500Vrms, providing enhanced safety margin; (3) RoHS3 compliance certification is provided, supporting regulatory requirements.

Q: Are there packaging differences between these parts?

A: The 3FL88-130 packaging is specified as "-" (not detailed). The FP88-130 is packaged in Box format. Both components use identical PC pin termination and through-hole mounting, ensuring compatibility with standard PCB assembly processes.

Q: What is the height difference between these transformers?

A: The FP88-130 seated height is 26.97mm, compared to 27.05mm maximum for the 3FL88-130. This 0.08mm difference is within acceptable tolerance for through-hole PCB applications and does not affect mechanical fit or clearance considerations.

Q: Does the FP88-130 provide better isolation performance?

A: The FP88-130 isolation voltage rating of 2000Vrms exceeds the 3FL88-130 specification of 1500Vrms. This represents a 33% increase in isolation voltage capability, providing additional safety margin in applications requiring high isolation performance.

Q: Is the FP88-130 RoHS compliant?

A: Yes. The FP88-130 carries ROHS3 compliance certification. The 3FL88-130 RoHS status is not specified in available documentation.
