Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the FP16-150 are grouped into two categories based on substitution compatibility:

Direct Equivalent (Identical Electrical & Mechanical Parameters): The FP16-150-B is a direct equivalent differing only in packaging format (Bulk versus Box). All electrical specifications, mechanical dimensions, and performance characteristics are identical to the main part.

Functional Equivalents (Matching Electrical Parameters with Design Variations): The 229E16 (Hammond Manufacturing) and 3FL16-150 (Tamura) are functional equivalents that match all critical electrical parameters: primary voltage options (115V/230V), secondary voltage outputs (8V parallel, 16V series), output current ratings (300mA parallel, 150mA series), and power rating (2.5VA nominal). These parts utilize alternative core technologies (semi-toroidal and laminated respectively) and may differ in physical dimensions, weight, and isolation voltage ratings. Substitution is valid when electrical performance requirements are met and physical space constraints are accommodated.

Key Parameters Determining Substitution Validity:

• Primary voltage compatibility (115V, 230V dual input)
• Secondary voltage outputs (8V parallel, 16V series)
• Output current capacity (300mA parallel, 150mA series minimum)
• Through-hole mounting capability
• PC pin termination style
• Power handling capacity (2.5VA or greater)

Engineering Selection Recommendations

FP16-150-B Selection Criteria: Select the FP16-150-B when bulk packaging is preferred and identical electrical and mechanical specifications are required. This part maintains full compatibility with the FP16-150 and is suitable for high-volume production environments. Both parts carry ROHS3 compliance and REACH Unaffected status, ensuring regulatory alignment.

229E16 Selection Criteria: The 229E16 is suitable for applications where semi-toroidal core technology is acceptable and physical space permits a smaller footprint (39.62mm L × 47.75mm W). The 229E16 operates at 2VA nominal power rating, which is 0.5VA lower than the FP16-150. This part is appropriate for designs with reduced power demands or where the lower isolation voltage (1750Vrms versus 2000Vrms) meets application requirements. ROHS3 compliance and REACH Unaffected status are maintained.

3FL16-150 Selection Criteria: The 3FL16-150 is suitable for applications requiring laminated core technology with identical 2.5VA power rating. This part features increased physical dimensions (63.50mm L × 50.80mm W × 27.05mm H seated), which must be accommodated in the design layout. The 3FL16-150 operates at 1500Vrms isolation voltage, lower than the FP16-150. This part is appropriate when space constraints are not limiting and RoHS compliance (without specific ROHS3 designation) is acceptable.

Regulatory Compliance: All substitute parts maintain active product status and RoHS compliance. The FP16-150 and FP16-150-B carry ROHS3 and REACH Unaffected certifications. The 229E16 carries ROHS3 and REACH Unaffected certifications. The 3FL16-150 carries RoHS compliance designation. All parts are classified under ECCN EAR99 and HTSUS 8504.31.4035.

Frequently Asked Questions (FAQ)

Q: Can the FP16-150-B be used as a direct replacement for the FP16-150?

A: Yes. The FP16-150-B is a direct equivalent with identical electrical specifications, mechanical dimensions, and performance characteristics. The only difference is packaging format (Bulk versus Box). Both parts are ROHS3 compliant and REACH Unaffected.

Q: What are the key differences between the FP16-150 and the 229E16?

A: The 229E16 differs in three primary aspects: (1) core technology (semi-toroidal versus laminated), (2) power rating (2VA versus 2.5VA), and (3) isolation voltage (1750Vrms versus 2000Vrms). All electrical output parameters (primary voltage, secondary voltage, and output current) are identical. Physical dimensions differ slightly, with the 229E16 being more compact in length (39.62mm versus 47.63mm).

Q: Is the 3FL16-150 suitable for high-isolation applications?

A: The 3FL16-150 operates at 1500Vrms isolation voltage, which is lower than the FP16-150 (2000Vrms). Applications requiring 2000Vrms isolation should use the FP16-150 or FP16-150-B. The 3FL16-150 is suitable for applications with isolation requirements of 1500Vrms or lower.

Q: What physical space considerations apply when substituting the 3FL16-150?

A: The 3FL16-150 has larger dimensions than the FP16-150: length 63.50mm (versus 47.63mm), width 50.80mm (versus 39.67mm), and seated height 27.05mm (versus 16.51mm). Verify that the PCB layout and enclosure accommodate these increased dimensions before substitution.

Q: Are all substitute parts through-hole mounted with PC pin termination?

A: Yes. All substitute parts (FP16-150-B, 229E16, and 3FL16-150) feature through-hole mounting and PC pin termination style, ensuring compatibility with standard PCB assembly processes.

Q: What is the power handling difference between the FP16-150 and 229E16?

A: The FP16-150 is rated at 2.5VA maximum power, while the 229E16 is rated at 2VA maximum power. The 229E16 has a 0.5VA lower power capacity. Verify that application power requirements do not exceed 2VA before selecting the 229E16.

Q: Do all substitute parts meet the same regulatory standards?

A: All parts are ROHS3 compliant and REACH Unaffected, with the exception of the 3FL16-150, which carries RoHS compliance without specific ROHS3 designation. All parts are classified under ECCN EAR99 and HTSUS 8504.31.4035. Verify specific regulatory requirements for your application region.

Q: Can the FP16-150 be substituted with the 229E16 in a design requiring 2.5VA power output?

A: No. The 229E16 is rated at 2VA maximum power, which is insufficient for applications requiring 2.5VA output. Use the FP16-150, FP16-150-B, or 3FL16-150 for 2.5VA applications.
