Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the FP40-150 is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Requirements:

• Identical power rating: 6VA
• Matching primary voltage options: 115V and 230V
• Matching secondary voltage configurations: Parallel 20V and Series 40V
• Matching maximum output current specifications: Parallel 300mA and Series 150mA
• Dual primary and dual secondary winding configuration
• Isolation voltage rating of 1750Vrms or higher

Mechanical Compatibility Requirements:

• Through-hole mounting type
• PC pin termination style
• Physical dimensions compatible with standard PCB layouts

Regulatory Compliance Requirements:

• RoHS3 compliance
• REACH Unaffected status
• EAR99 classification

The Hammond Manufacturing 229A40 meets all electrical equivalence criteria, maintains mechanical compatibility, and satisfies all regulatory requirements, establishing it as a valid substitute part.

Engineering Selection Recommendations

FP40-150 (Triad Magnetics - Laminated Core):

• Primary selection for applications requiring 2000Vrms isolation voltage specification
• Laminated core construction provides established performance characteristics
• Active product status with continuous inventory availability (965 units in stock)
• Flat Pack™ series designation indicates optimized form factor

229A40 (Hammond Manufacturing - Semi-Toroidal):

• Valid substitute when 1750Vrms isolation voltage meets application requirements
• Semi-toroidal core construction offers alternative electromagnetic performance profile
• Active product status with established supply chain (791 units in stock)
• Bulk packaging option available
• Lighter weight (0.37 lb vs. 0.438 lb) may benefit space-constrained applications

Both parts maintain full RoHS3 compliance and REACH Unaffected status, satisfying regulatory requirements for industrial and commercial applications. Selection between these parts should be based on isolation voltage requirements, available board space, and core construction preference for the specific application.

Frequently Asked Questions (FAQ)

Q: Can the 229A40 directly replace the FP40-150 in existing designs?

A: The 229A40 provides electrical equivalence across all primary specifications: 6VA power rating, dual 115V/230V primary windings, dual 20V/40V secondary windings, and 300mA/150mA output current ratings. Physical dimensions differ slightly (39.62mm L x 47.75mm W vs. 47.63mm L x 39.67mm W), requiring PCB layout verification. The 1750Vrms isolation voltage of the 229A40 is lower than the FP40-150's 2000Vrms specification and must be confirmed as acceptable for the application.

Q: What is the difference between laminated and semi-toroidal core construction?

A: The FP40-150 uses laminated core construction, while the 229A40 uses semi-toroidal construction. Both are established transformer technologies. Core type differences do not affect the electrical parameters provided in this reference (voltage, current, power rating, isolation voltage). Selection between core types depends on application-specific requirements such as EMI characteristics, efficiency curves, or thermal performance not specified in this comparison.

Q: Are both parts suitable for the same mounting applications?

A: Both parts feature through-hole mounting with PC pin termination, establishing mechanical compatibility. However, physical dimensions differ: FP40-150 measures 47.63mm L x 39.67mm W x 22.23mm H, while 229A40 measures 39.62mm L x 47.75mm W x 21.59mm H. PCB layout and clearance requirements must be verified before substitution.

Q: Do both parts meet the same regulatory standards?

A: Both the FP40-150 and 229A40 are RoHS3 compliant and REACH Unaffected, satisfying equivalent regulatory requirements. Both carry EAR99 classification and share the same HTSUS code (8504.31.4035).

Q: What is the significance of the isolation voltage difference?

A: The FP40-150 specifies 2000Vrms isolation voltage, while the 229A40 specifies 1750Vrms. Both values represent the maximum voltage that can be safely applied between primary and secondary windings. The 229A40's lower specification must be confirmed as acceptable for the application's isolation requirements before substitution.
